Usayizi ojwayelekile we-Storz coupling ubaluleke kakhulu ukuqinisekisa ukusebenzisana, ukuphepha, nokusetshenziswa ngokushesha ezinhlelweni zesimanje zokuvikela umlilo emhlabeni wonke. Ngaphandle kolimi olujwayelekile lwezilinganiso, abacimi bomlilo nabanjiniyela babeyohlale bexakekile ukufanisa amapayipi, ama-hydrant, nokuxhumana kwe-standpipe phakathi kwezimo eziphuthumayo lapho isekhondi ngayinye ibalulekile. Uhlelo lwe-metric DN (Diameter Nominal) lunikeza uhlaka olungaguquguquki lokucacisa ububanzi obuqondile be-bore bezingxenye ze-Storz, luqeda ukuqagela futhi lunciphise ingozi yezinto ezingahambisani endaweni yomlilo. Lo mhlahlandlela ophelele wezilinganiso ugxila ikakhulukazi kumayunithi amahlanu avame kakhulu we-metric Storz — DN40, DN50, DN65, DN80, kanye ne-DN100 — futhi uhlinzeka ngobubanzi bangaphandle obuqondile, amaphethini ezimbobo zamabhawodi, izilinganiso zamagasketi, kanye namazinga ajwayelekile okucindezela abadinga ochwepheshe ukucacisa, ukuthenga, nokufaka izingxenye ezifanele. Noma ngabe ungunjiniyela wokuvikela umlilo uklama uhlelo olusha lwe-sprinkler yezentengiselwano, igunya lamanzi kamasipala elibuyekeza ukuxhumana kwe-hydrant, noma uchwepheshe wokuthenga osakha izingxenye ezishintshayo ze-Storz esikhungweni sezimboni, ukuba nomthombo onokwethenjelwa wezilinganiso ze-Storz kubalulekile ukuze kufezeke ukuxhumana okungavuqi, okudlulisela kakhulu njalo. Ngaphezu kwalokho, ukuqonda ubudlelwano phakathi kosayizi ojwayelekile nezilinganiso zangempela kusiza ukugwema amaphutha abiza kakhulu lapho kufakwa izixhumi ze-Storz nezixhumi ezine-thread, izingxenye zokunweba, noma imicengezi yokunciphisa evela kubakhiqizi abahlukene.

Ngesikhathi sokuphela kwalo mhlahlandlela, uzoba nemodeli ecacile yengqondo yokuthi ubukhulu be-DN busebenza kanjani, yiziphi izilinganiso okufanele uzihlole ngaphambi kokuthenga, nokuthi ungakhetha kanjani izinto ezifanele ze-Storz coupling kanye nezinga lokucindezela lesicelo sakho esithile. Ul

I-Storz coupling, eyasungulwa eJalimane ekupheleni kwekhulu le-19 nguCarl August Guillemin, yashintsha kakhulu ukuxhunywa kwamapayipi omlilo ngokwethula umklamo ofanayo, ongahlukanisi ubulili, owasusa isidingo sezinhlangothi zikayise nezikayise ezingxenyeni ezihlukene zepayipi. Ngaphambi kwalokhu kuthuthukiswa, abacimi bomlilo babedinge ukubambana namapayipi anezintambo ayedinga ukuhlelwa ngokucophelela futhi ayengadideka kalula ngaphansi kwengcindezi yesimo esiphuthumayo, okubambezele ukulethwa kwamanzi futhi kwandise ingozi yokwehluleka kokuxhumana. Umklamo we-Storz usebenzisa izinhlangothi ezifanayo zokuxhuma kuzo zombili iziphetho zepayipi ngalinye, ngezingxenye ezihlangene ezishelela ezindaweni ezihambelanayo kanye nomshini wokukhiya wekota ojikelezayo owakha uxhumano oluphephile, olungavuzi ngaphandle kwamathuluzi nhlobo. Le ndlela yokungahlukanisi ubulili yenza kube lula kakhulu ukuhlanganisa amapayipi ensimini ngoba ipayipi elinye eline-Storz lingaxhunywa kunoma iyiphi enye ipayipi noma insiza ye-Storz kungakhathalekile ukuthi libhekephi, kunciphisa izidingo zokuqeqeshwa futhi kusheshe izikhathi zokuphendula phakathi nezingozi eziyinkimbinkimbi. Ama-Storz couplings amanje enziwa ngezinto ezahlukahlukene ezifaka i-aluminum eqinisiwe, ithusi, insimbi engagqwali, nama-polymers alula, ngalinye linikeza izivumelwano ezihlukene phakathi kwesisindo, ukumelana nokugqwala, izindleko, nesilinganiso sokucindezela kwezimo ezithile zokusetshenziswa. Le coupling isetshenziswa kabanzi hhayi kuphela kumapayipi omlilo kodwa futhi nasezindaweni zokukhipha amanzi zomlilo, ukuxhumana kwezicishamlilo (FDCs), izinhlelo ze-standpipe, ama-monitor aphathwayo, nemigqa yokuhlinzeka enobubanzi obukhulu lapho ukuxhumana nokukhipha okusheshayo kuyizinto ezibalulekile ekusebenzeni.

E-Nyakatho Melika, izixhumi ze-Storz sezikhula zithandwa kakhulu emashumini amabili eminyaka adlule njengoba iminyango yomlilo kamasipala yamukela ulayini omkhulu (LDH) wokusebenza kokuhlinzekwa ngamanzi futhi njengoba izindinganiso ze-NFPA zikhuthaze ukuhambisana kule ndlela yokuxhuma eqinisekisiwe. Isixhumi se-Storz siyindlela yokuxhuma ebusayo emazweni amaningi aseYurophu, izingxenye ze-Asia, i-Middle East, ne-Australia, okwenza sibe yindinganiso yomhlaba wonke yokulwa nomlilo nokusingatha uketshezi lwezimboni. Ukuqonda ukwakheka okuyisisekelo kwesixhumi se-Storz — okuhlanganisa nezimbambo eziphakemayo, imbobo yangaphakathi ye-gasket, izindlebe zokukhiya, kanye nesici sokujikeleza kumiklamo ethile — yisinyathelo sokuqala sokuqonda ukuthi kungani ukulawulwa okucacile kobukhulu kubaluleke kangaka ekusebenzeni okuthembekile. Ngisho nokuhlukahluka okuncane ekuphakameni kwezimbambo noma ububanzi be-groove kungadala ukuthi isixhumi sishaye, sivuze, noma sihluleke ngaphansi kwengcindezi, yingakho abakhiqizi abahlonishwayo njengalabo esizoxoxa ngabo kamuva banamathela kumikhawulo eqinile yobukhulu kuwo wonke usayizi we-DN. Uma uvakashelaAma-Storz Coupling ekhasini lomkhiqizo kwaVaricpand International, uzothola ububanzi bezosayizi nezinto ezihambisana nalezi zindinganiso eziqine kakhulu, uqinisekisa ukuthi uhlelo lwakho lokuvikela umlilo luhlala luthembekile futhi luhambisana nekhodi iminyaka eminingi. Manje njengoba sesibekile ukubaluleka okuyisisekelo kwezixhumi ze-Storz emililweni yesimanje, ake singene sijule ohlelweni lokulinganisa lwe-DN olusekelayo lonke umhlahlandlela wepharamitha yobukhulu.

I-DN, okusho ukuthi i-Diameter Nominal, iyindlela eyaziwa umhlaba wonke yokukala ububanzi bangaphakathi obuqondile bezishimula, amapayipi, nezingxenye zawo, futhi ihlinzeka ngereferensi eyenziwe yaba eyodwa ehamba phambili emingceleni kazwelonke nezinhlelo zokulinganisa. Ngokubhekisela kuma-Storz couplings, inombolo ye-DN ibhekisa kububanzi obuqondile bokungena kweshimula noma ipayipi lapho i-coupling yakhelwe ukuba ilingane khona, iboniswe ngamamitha, ngakho-ke i-DN65 Storz coupling ihloselwe ukusetshenziswa neshimula noma ipayipi elinomubanzi wangaphakathi onemitha angu-65. Kubalulekile ukuqonda ukuthi inani le-DN liyisilinganiso esiqondile, hhayi isilinganiso esiqondile sobubanzi bangaphandle be-coupling noma ububanzi obungena ku-fitting uqobo; ububanzi bangaphandle bangempela buyahlukahluka ngomkhiqizi ngaphakathi kwemingcele echaziwe, kanti usayizi oqondile usebenza njengendlela elula yokubeka amagama ukuze kuhambisane izingxenye. Ngokwesibonelo, i-DN100 Storz coupling ihambelana cishe noxhumano lwamayintshi angu-4 ohlelweni lwamayintshi, okwenza kube ukufakwa esikhundleni esiqondile ezindaweni eziningi lapho imishini yakudala esekelwe emayintshini isikhutshazwa noma ivunyelaniswa nezindinganiso zamamitha. Ubuhlobo phakathi kobukhulu be-DN namayintshi akuhlale kuyikuguquko oluqondile lwezibalo, kodwa izilinganiso ezilandelayo eziyisilinganiso zamukelwa kabanzi embonini yezokuvikela umlilo: i-DN40 iyalingana namayintshi angu-1½, i-DN50 iyalingana namayintshi angu-2, i-DN65 iyalingana namayintshi angu-2½, i-DN80 iyalingana namayintshi angu-3, kanye ne-DN100 iyalingana namayintshi angu-4. Lezi zilinganiso zivumela onjiniyela nabathengi ukuthi babheke phakathi kwezincwadi zamamitha nezamathuluzi, nakuba kuhlale kudingeka ukuqinisekisa isilinganiso sangempela sobuso be-coupling nendawo ye-gasket ngaphambi kokucabanga ngokuhambisana phakathi kwemikhiqizo noma izifunda zokukhiqiza.

Uma ukhetha isixhumi esifanayo se-Storz sosayizi othile we-DN, kufanele ucabangele hhayi kuphela ububanzi obuqokiwe kodwa futhi nesilinganiso sokucindezela, ububanzi bokushisa, izinto ze-gasket, kanye nohlobo lwendlela yokukhiya (i-lug e fixed noma uhlobo olujikelezayo) olufaneleka kakhulu imvelo yakho yokusebenza. Ipharamitha zobukhulu ezibaluleke kakhulu ngokuhambisana zihlanganisa ububanzi bangaphandle bomzimba wesixhumi, ububanzi bomjikelezo we-pitch wezikhala ze-lug, inani kanye nesimo sama-lug, ukujula komsele we-gasket, kanye nobubanzi bangaphakathi obuhlangana ne-hose shank noma i-threaded adapter. Ukungahambisani kunoma yimaphi kula makhulu kungaholela ekuvuza, ukuhlukana kwesixhumi, noma ukulimala kwe-gasket ngesikhathi sokuqinisa, yingakho abahlinzeki abahlonishwayo banikeza amashidi emininingwane yobuchwepheshe kuwo wonke usayizi we-DN nenketho yezinto abazinikezayo. Uma uhlanganisa izixhumi ze-Storz ohlelweni olukhona olusebenzisa izintambo ze-NPT (National Pipe Taper) noma izintambo ze-BSP (British Standard Pipe), uzodinga ukusebenzisa ama-threaded adapters aguqula ifomu lentambo esibonakalweni se-Storz ngenkathi ugcina amandla okudonsa we-DN. Abakhiqizi abaningi, okubandakanya labo abavezwe kuI-Aluminum Storz CouplingkanyeI-Brass Storz Coupling amakhasi, sinikeza la ma-adapter njengezinto ezijwayelekile, okwenza kube lula ukuguqukela kusuka ezinhlelweni ezindala ezinezintambo kuya kuxhumano lwesimanje olusekelwe ku-Storz. Esigabeni esilandelayo esikhulu, sizochaza imingcele eqondile yobukhulu bayo yonke imibhangiso emihlanu ye-DN, sinikeze idatha yenombolo abayidingayo onjiniyela nabachwepheshe ukuze benze izinqumo ezinekhono.

I-DN40 Storz coupling, efana cishe noxhumano lwe-1½-inch, ngokuvamile isetshenziselwa imigqa yokuhlasela enobubanzi obuncane, imibhobho ye-booster, nezinye izicelo zokudlulisa uketshezi lwezimboni lapho ukugeleza okumaphakathi nesisindo esilula kuyizinto ezibalulekile. Ububanzi bangaphandle obuqanjwe ngegama lomzimba we-DN40 Storz coupling cishe bungama-76 mm, nobungqimba bomgodi obungama-40 mm ukuze buhambisane nobubanzi bangaphakathi bohose, futhi i-coupling ngokuvamile inezimbambo ezine ezihlelwe kububanzi bomjikelezo we-pitch obungama-62 mm. Ububanzi besihlalo segasket se-DN40 Storz coupling ngokuvamile bungama-54 mm, futhi ububanzi begasket obujwayelekile bungama-4 kuye ku-5 mm, eyenziwe nge-EPDM noma irabha ye-nitrile kuye ngezidingo zokuhambisana noketshezi. Ngenxa yesayizi layo elincane, i-DN40 Storz coupling iyathandwa ukusetshenziswa kumahose omlilo wehlathi, iziteshi zamahose ezakhiweni, kanye nezindawo ezincane zobubanzi zamapayipi amanzi emizileni kamasipala lapho isikhala sikhawulelwe futhi ukuxhumana okusheshayo kuyaziswa. Isilinganiso sokucindezela se-DN40 Storz coupling ejwayelekile ye-aluminium ngokuvamile singama-200 psi (14 bar), kanti izinguqulo zethusi ezihlotshelwe zingakwazi ukubhekana no-300 psi (21 bar) wezicelo zezimboni noma zasolwandle ezinokucindezela okuphezulu. Lapho ukhetha i-DN40 Storz coupling, qinisekisa ukuthi ubukhulu bezimbambo nokujula komgodi kuhambisana nengxenye ehambisanayo oyihlose ukuyixhuma, njengoba amanye ama-coupling aseYurophu amadala asebenzisa amaprofayili ahlukile kancane kunenguqulo yesimanje ehambisana ne-NFPA.Izesekeli ze-Storz ikhasi lihlinzeka ngama-caps, ama-plugs, namagasket alinganiswe ngokukhethekile ukuxhumana kwe-DN40 ukuqinisekisa ubuqotho obuphelele bohlelo.

I-DN50 Storz coupling, ehambelana noxhumano olungu-2-intshi, ingenye yobukhulu obusetshenziswa kakhulu ezicishamlilo nasezimbonini ngoba inikeza ibhalansi enhle yokugeleza kwamanzi, isisindo, nokulula ukuphatha izivunguvungu eziphakathi. Ububanzi bangaphandle bomzimba ojwayelekile we-DN50 Storz coupling bungaba ngu-90 mm, bububanzi obungama-50 mm obudlula kuyo ukuze kuhambisane nobubanzi bangaphakathi besivunguvungu, futhi izimbambo ezine zibekwe kububanzi bomjikelezo ongaba ngu-75 mm. Indawo yokubeka igasket ku-DN50 coupling inobubanzi obungaba ngu-67 mm, enobujula besikhala esingu-5 mm ukuze kube khona i-O-ring ejwayelekile noma igasket eyisicaba eyakha isitembu esithembekile ngaphansi kwengcindezi. Izicelo ezijwayelekile ze-DN50 Storz zihlanganisa izicishamlilo ezihlaselayo, izivunguvungu zokuhlasela ezixhunyiwe, izivunguvungu zokuhlinzeka ngamanzi ezimbonini, kanye nezindawo zokukhipha amanzi ezinhlelweni zokuvikela ezicishamlilo zikamasipala nezizimele lapho kudingeka ukugeleza kusuka ku-250 kuye ku-500 GPM. Imicengezi eminingi yezicishamlilo ijwayele ukusebenzisa i-DN50 (2-intshi) Storz ezivunguvungwini zayo ezisetshenziswa kakhulu ngoba i-coupling ilula ngokwanele ukuze iphathwe yisicishamlilo esisodwa kodwa inkulu ngokwanele ukuletha umthamo omkhulu wamanzi ezicishamlilo zezakhiwo kanye nemisebenzi yasemadolobheni yasendaweni. Lapho usebenzisa i-DN50 Storz coupling nezivunguvungu ezenziwe ngamazinga ahlukene, njengezivunguvungu zamamitha ezibhalwe njenge-52 mm ID, umehluko omncane wobukhulu ungavunyelwa yi-clamp yesivunguvungu kodwa kufanele kuqinisekiswe nomkhiqizi ukuze kugwenywe ukushelela noma ukuvuza. Ezicishamlilo eziphakeme njengezinhlelo zokujova i-foam noma izindawo zokuhlola ingcindezi, ubukhulu be-DN50 buyatholakala kuzo zombili izinhlobo ezijwayelekile nezisindayo ezinemibambo eqiniswe ngamandla nezindonga zomzimba ezishubile.Ama-Storz Coupling Ensini Yensimbi inketho inikeza ukumelana okungcono kakhulu nokugqwala kwezicelo ze-DN50 ezindaweni zasolwandle, zamakhemikhali, noma zamanzi amdaka lapho i-aluminium noma ithusi kungase konakale ngokuhamba kwesikhathi.

I-DN65 Storz coupling ilingana ne-metric ye-2½-inch connection, okungenzeka ukuthi iyona enkulu kunazo zonke ezisetshenziswa emlilweni eNyakatho Melika ngoba ihambelana nomugqa wokuhlasela omkhulu ojwayelekile osetshenziswa ezinkampanini eziningi zemishini kanye namaphakethe e-hose. Ububanzi bangaphandle be-DN65 Storz coupling cishe bungama-108 mm, nenombolo engu-65 mm ehambelana nobubanzi bangaphakathi be-2½-inch fire hose, kanti ama-lugs ahlelwe ebubanzi bomjikelezo we-pitch obungaba ngu-90 mm. Ububanzi besihlalo segasket osayizi we-DN65 ngokuvamile bungama-80 mm, nenobubanzi begroove obungama-6 mm obuhlinzeka ngendawo eyanele yokubeka uphawu ukuze i-elastomeric gasket icindezeleke futhi yakhe umhlangano ongenavuza kumazinga okucindezela okusebenzayo afinyelela ku-200 psi. Enye yemibuzo ejwayelekile kakhulu mayelana nokuhambisana kwe-DN65 Storz couplings iphathelene nokuthi ingashintshwa yini nezixhumanisi eziyi-2½-inch threaded (NST noma NH threads), ezisatholakala kabanzi kuma-hydrants amadala, izindawo zokuphuma ze-standpipe, kanye nezi-fire department connections. Ukuze uxhumane phakathi kwe-DN65 Storz ne-2½-inch NPT noma i-NH thread, udinga i-adapter eyakhelwe injongo eshintsha ifomu le-thread kanye nobulili esikhombimsebenzini se-Storz ngenkathi igcina indawo efanayo yokugeleza kanye nesilinganiso sokucindezela. Lezi zixhumanisi ziyatholakala ku-aluminum, i-brass, ne-stainless steel ezivela kubakhiqizi abanjengoVaricpand futhi zifakwa ohlwini ku-Ama-Storz Couplingikhasi lomkhiqizo kanye nama-gaskets ahambelanayo namaphini okubamba. Imicengezi yomlilo ehamba kusuka ku-threaded kuya ku-Storz connections ngokuvamile ikhetha i-DN65 njengosayizi ojwayelekile wezintambo zokuhlasela ngoba inikeza isici sokugeleza esijwayelekile ngenkathi iqeda izinkinga zokuxhuma okungalungile nokuhambisana kwe-gasket ezixhunywa nge-threaded phakathi nokusetshenziswa okucindezelwe kakhulu. Ngaphezu kwalokho, imicengezi eminingi yomlilo yesimanje manje iza neziphumo ze-DN65 Storz njengemishini ejwayelekile, ikakhulukazi ezindaweni ezamukele i-NFPA 1963 noma izindinganiso ezifanayo zaseYurophu zamalungu ombiza womlilo.

I-DN80 Storz coupling, ehambelana cishe noxhumo lwe-intshi engu-3, ihlala endaweni ebalulekile ezinhlelweni zokuvikela umlilo ezidinga ukugeleza okuphezulu kunezinganikezwa yi-DN65 kodwa lapho i-DN100 coupling egcwele engu-4-inch ingaba nkulu futhi ingasindi kakhulu. Ububanzi bangaphandle bomzimba we-DN80 Storz coupling bungaba ngu-124 mm, no-bore ngokusebenzisa okufanelekayo okungu-80 mm okusekela ukugeleza kusuka ku-500 kuye ku-800 GPM kuncike kubude be-hose nomfutho wokusebenza. Ama-lugs ku-DN80 coupling avame ukuhlelwa ku-pitch circle diameter engaba ngu-105 mm, futhi ububanzi besihlalo segasket bungaba ngu-96 mm no-groove ejulile ukuze kuhlaliswe ama-O-rings ajwayelekile namagasket ayisicaba ezindebeni ezahlukene. I-DN80 Storz couplings ivame ukutholakala ezinhlelweni ze-standpipe ezakhiweni eziphakeme, lapho isebenza njengoxhumo lwe-hose ku-valve ngayinye yezitebhisi, inikeza abacimi bomlilo isixhumi esithembekile, esisheshayo sokudlulisela imigqa yokuhlasela phezulu ezitebhisini nasemazindeni anomlilo. Ziphinde zisetshenziswe njengoxhumo lomugqa wesipho sabaqaphi abasheshayo, abaqaphi bomhlaba, kanye ne-large-diameter hose relays lapho kudingeka ukugeleza okumaphakathi ukuhlasela okude noma izimo zokushushumbisa amanzi. Ngenxa yokuthi i-DN80 ihlukanisa umngcele phakathi kwe-medium ne-large-diameter hosing, ngezinye izikhathi isetshenziswa njengosayizi wokunciphisa phakathi komugqa wesipho we-DN100 nomugqa wokuhlasela we-DN65, okuvumela abacimi bomlilo ukuthi banciphise ukugeleza kancane ngaphandle kokudideka okweqile noma ukulahleka komfutho. Lapho ucacisa i-DN80 Storz coupling yohlelo lwe-standpipe, kubalulekile ukuqinisekisa ukuthi isilinganiso somfutho sihambelana nokuphuma kwe-fire pump yesakhiwo, okungadlula u-200 psi kwezinye izindawo eziphakeme, ukuze kuqinisekiswe ukuthi i-coupling ayiyona ingxenye ebuthakathaka ohlelweni.

I-DN100 Storz coupling yilona enkulu kunazo zonke kulo mhlahlandlela, ilingana noxhumano lwe-intshi engu-4, futhi yakhelwe ngokukhethekile imisebenzi yokuhlinzeka nge-high-flow lapho amanzi kufanele athuthwe ngokushesha nangempumelelo kude noma ukuhlinzeka ngezinto ezinkulu ezifana ne-aerial master streams nama-portable deluge sets. Ububanzi bangaphandle bomzimba ojwayelekile we-DN100 Storz coupling cishe bungama-152 mm, no-bore ongu-100 mm ovumela amanzi ukuthi agele ngaphezu kwe-1000 GPM emicindezelweni emaphakathi, okulinganiselwe ikakhulukazi ububanzi behose kanye nomthamo womthombo wokuhlinzekwa ngamanzi. Ama-lugs ku-DN100 coupling ahlelwe ngobubanzi bomjikelezo we-pitch cishe bungama-130 mm, futhi ububanzi besihlalo segasket bungama-120 mm, okudinga igasket eqinile enesigaba esiphambanayo esingu-6 kuye ku-7 mm ukuze kugcinwe uphawu ngaphansi kwamanzi aphezulu kanye nemicindezelo evamile emisebenzini ye-large-diameter hose. Izinto ze-DN100 Storz yisona sixhumanisi esijwayelekile kuma-fire department pumpers amaningi we-large-diameter supply hose (LDH) intakes and discharges, okuvumela ukuxhumana okusheshayo nama-hydrants, ama-water tenders, nama-relay pumping setups ngaphandle kwesidingo sama-threaded adapters noma ama-wrenches amaningi. Futhi yisona sikhulu esiphambili sama-fire department connections (FDCs) ezakhiweni zezentengiselwano, lapho izinhlelo ze-sprinkler ne-standpipe zidinga ukuhlinzekwa ngamanzi amaningi kusuka kuma-fire apparatus ukuze kuxhaswe ukuhlinzekwa ngamanzi kwangaphakathi kwesakhiwo ngesikhathi somlilo. Ngenxa yamandla amakhulu abandakanyeka ekusingatheni i-hose engu-4-inch kumazinga aphezulu okugeleza, ama-DN100 Storz couplings avame ukwenziwa nge-forged aluminum noma ama-lightweight alloys ukuze kuncishiswe umthwalo ongokwenyama kubacimi bomlilo ngenkathi kugcinwa amandla adingekayo ukuze kusebenze ngokuthembekile emicindezelweni efika ku-200 psi. Ezigabeni zezimboni ezibandakanya ama-slurries anokuklebhula, amakhemikhali anokugqwala, noma izinga lokushisa elidlulele, ama-stainless steel DN100 Storz couplings ahlinzeka ngokuqina okuthuthukisiwe futhi atholakala ngokusebenzisa i-Ama-Storz Coupling Ensini Yensimbi uhla lomkhiqizo kwa-Varicpand, siqinisekisa isikhathi eside sokuphila ngisho nasezindaweni ezinzima kakhulu.

Enye yezinselelo ezivame ukuhlangatshezwana nazo lapho kuhlanganiswa izixhumi ze-Storz ohlelweni olukhona lokuvikela umlilo ukuthola ukuhambisana phakathi kobukhulu obuhlukahlukene be-DN, kanye naphakathi kwezixhumi ze-Storz nezixhumi ezindala ezine-thread njenge-NPT, i-BSP, noma i-NH (National Hose) threads. Umklamo we-Storz ngokwemvelo unobukhulu bawo, okusho ukuthi uhhafu wesixhumi se-DN65 ngeke ukwazi ukuxhuma kuhhafu wesixhumi se-DN80 ngoba izikhundla zamalugu nobubanzi bomzimba behlukile, okudinga ukusetshenziswa kwe-adapter ezinciphisa noma ezandisayo lapho kudluliselwa phakathi kobukhulu ekuhleleni kombhobho. I-adapter yokunciphisa, isibonelo, ingaba nesixhumi sowesifazane se-DN100 Storz kwenye iphela kanye nesixhumi sowesilisa se-DN65 Storz kwenye iphela, okuvumela umbhobho wokuhambisa omkhulu ukuthi uhambise umbhobho wokuhlasela omncane ngaphandle kokudinga imiqulu yombhobho ehlukene yobukhulu obuhlukahlukene. Ngokufanayo, ama-adapter okwandisa enza okuphambene, aqala ku-DN encane aye ku-DN enkulu, okungaba usizo lapho okuphuma ku-hydrant kungu-DN65 kodwa umbhobho wokuhambisa ungama-DN100 futhi udinga ukwandisa amandla okugeleza kude kakhulu. Lapho uguqula phakathi kwezinhlelo ze-Storz nezine-thread, i-adapter akumele ihambisane nesimo se-thread nobukhulu kuphela kodwa futhi ivumele isilinganiso sokucindezela kanye nohlobo lwegasket lwecala le-Storz, yingakho kubalulekile ukusebenzisa ama-adapter enzelwe ngokukhethekile insizakalo yokuvikela umlilo kunokuba izixhumi ezijwayelekile zokufakwa kwamanzi. Amanye ala ma-adapter afaka indawo yokubamba eyi-hexagonal noma eyi-knurled ukuze iqine ngesandla, kanti amanye afaka izikhonkwane zokukhiya noma izikrufu zokubeka ukuze kuvinjelwe ukungaxhunywa ngephutha ngaphansi kokudlidliza nokunyakaza kokubamba umbhobho ngesikhathi semisebenzi yokulwa nomlilo.Izesekeli ze-StorzLesi sigaba sihlinzeka ngohlu oluphelele lwama-reducer, ama-cap, ama-plug, nama-gasket emboza zonke izinguquko ezivamile zamasayizi nokuguqulwa kwezintambo, okwenza kube yinsiza ebalulekile kubaklami besistimu kanye nabasebenzi bokulungisa abadinga ukuqinisekisa ukuhambisana okuphelele kuzo zonke izinto zabo zamapayipi namadivayisi. Lapho ukhetha i-adapter, hlola njalo isilinganiso sokucindezela, ububanzi bokushisa, nokuhambisana kwezinto nezinto ezibandakanyekayo, ikakhulukazi ezinhlelweni ezibandakanya ukugxilisa ukhwekhwe, amanzi olwandle, noma ama-ejenti amakhemikhali angasekhulise ukugqwala kwezinhlanganisela ezithile. Ngokwakha isitokwe sama-adapter nama-reducer esicabangelwe kahle, umnyango womlilo noma indawo yezimboni ingakwazi ukukhulisa ukuguquguquka kwesistimu yayo esekwe yi-Storz ngenkathi inciphisa inani lamalungu ahlukene okufanele agcinwe ukuze kusebenzwe nsuku zonke.

I-Varicpand International inikeza uhla olubanzi lwezixhumanisi ze-Storz kuzo zonke izinhlobo ezinhlanu ze-DN ezixoxwe kulo mhlahlandlela, ngezinketho eziningi zezinto kanye namabanga okucindezela ukuze uvumelane cishe nanoma yisiphi isidingo sokuvikela umlilo noma ukuphatha uketshezi lwezimboni. Kuzicelo ze-DN40 ne-DN50 lapho isisindo siyisici esibalulekile, njengezikhwama zokugawula izihlahla noma imigqa yokuhlasela esele ixhumeke kumadivayisi alula, izixhumanisi ze-Storz ze-aluminium zinikeza ibhalansi enhle yamandla, ukumelana nokugqwala, nokulula kokuphatha ngaphandle kokudela ukunemba kobukhulu okudingekayo ukuze kube nokuvalwa okuthembekile. Ezindaweni lapho kulindeleke ukuhlukunyezwa komshini, izinga lokushisa eliphezulu, noma ukuphinda ukuxhunywa, izixhumanisi ze-Storz zethusi zinikeza ukuqina okungcono kakhulu nempilo yesevisi ende, okwenza zibe ukukhetha okuncanyelwayo ezinhlelweni ze-standpipe, izindawo zokuqeqesha, kanye nezindawo zokukhipha amanzi ezisetshenziswa kakhulu lapho isixhumanisi singaxhunywa futhi sixhunywe izikhathi eziningi ngeviki. Kwezicelo ezidinga kakhulu ezihilela amanzi olwandle, ukucubungula amakhemikhali, noma ukudluliswa koketshezi oludliwayo, izixhumanisi ze-Storz zensimbi engagqwali zinikeza ukumelana nokugqwala okungafani nokuqeda okuphezulu okuhlangabezana namazinga aqinile omthetho ngenkathi kugcinwa ukuhambisana okuphelele kobukhulu neziqondiso ze-NFPA ne-EN. Inketho ngayinye yezinto iyatholakala kuzo zonke izinhlobo ezinhlanu ze-DN kusuka ku-DN40 kuya ku-DN100, ngokufana okungaguquki kwe-lug geometry, ubukhulu begroove ye-gasket, namabanga okucindezela acaciswe kahle kumashidi emininingwane yomkhiqizo atholakala ngeIzixhumi ze-StorzIkhasi lokubuka konke. Lapho ukhetha i-coupling efanele yesistimu yakho, qala ngokunquma usayizi we-DN odingekayo ngokusekelwe ku-diameter ye-hose yakho kanye ne-flow rate oyihlosile, bese ukhetha izinto ezihambisana kahle nezimo zemvelo yakho, isabelomali, kanye nokuvama kokusetshenziswa okulindelekile. Okulandelayo, hlolela isilinganiso sokucindezela ngokumelene nokucindezela okuphezulu kwesistimu yakho, engeza umkhawulo wokuphepha okungenani okungu-25% ukuze ubale ukwanda kokucindezela, ukushaywa kwamanzi, nemiphumela yokuguga phakathi nempilo yesevisi ye-coupling. Ekugcineni, cabanga ngezinto ze-gasket — ngokuvamile i-EPDM yesevisi yamanzi ejwayelekile, i-nitrile yezicelo ezimelana namafutha, noma i-silicone yezikhathi zokushisa eziphakeme kakhulu — futhi uqinisekise ukuthi i-gasket ihambisana nemidiya yoketshezi kanye nezinto zokuhlanza ezisetshenziswa emisebenzini yakho.

I-Varicpand iphinde ihlinzeke ngomugqa ophelele wezinsiza ze-Storz okubandakanya ama-gaskets, izivalo zothuli, iziphetho zamapulaki, nezinqamuzana zokukhiya zawo wonke usayizi we-DN, ukuze ukwazi ukuqedela uhlelo lwakho ngezingxenye eziqinisekisiwe ukuthi ziyahambisana nokucaciswa kobukhulu nokusebenza kwama-couplings ngokwawo. Ukuze uthole ama-oda wangokwezifiso afaka ukuguqulwa kwentambo okungajwayelekile, izilinganiso zokucindezela ezikhethekile, noma ukuhlanganiswa kwezinto ezihlukile, iqembu lobunjiniyela le-Varicpand lisebenza eduze namakhasimende ukuthuthukisa izixazululo ezenziwe ngendlela efanele ezihlangabezana nezidingo ezithile zezinhlelo zabo zokuvikela umlilo noma zokuphatha uketshezi lwezimboni. Ngokuhlanganisa ukuthengwa kwezingxenye zakho ze-Storz kumkhiqizi oyedwa ohlinzeka ngekhwalithi ehambisanayo kuwo wonke ububanzi be-DN, unciphisa ubungozi bokungahambisani kobukhulu, wenze lula ukuphathwa kwesitoko, futhi uthole ukwesekwa kwezobuchwepheshe kusuka kochwepheshe abaqonda imininingwane yobukhulu be-metric Storz nokusetshenziswa kwawo ezimeni zangempela zokulwa nomlilo. Noma ngabe uhlinzeka ngomshini omusha womlilo, ubuyekeza uhlelo lwe-hydrant kamasipala, noma uklama i-standpipe yomlilo ophakeme kusukela ekuqaleni, umhlahlandlela wokukhetha ohlinzekwe lapha — uhlanganiswe nemingcele enemininingwane yobukhulu sayo yonke usayizi we-DN — uzokusiza wenze izinqumo ezinolwazi ezithuthukisa ukuphepha, ukwethembeka, nokusebenza kahle kwezinhlelo zakho zokuvikela umlilo. Uma udinga usizo olwengeziwe ekukhetheni i-Storz coupling efanelekayo usayizi we-DN othile noma uhlelo lokusebenza, iqembu elinolwazi e-Varicpand liyatholakala ukuhlinzeka ngesiqondiso nezincomo ezisekelwe emashumini eminyaka yesipiliyoni embonini yokuvikela umlilo kanye neyokuhlanganisa izimboni.

Ngokufingqiwe, ukuqonda imingcele yobukhulu bezi-DN40, DN50, DN65, DN80, kanye nezi-DN100 Storz couplings kubalulekile kunoma ngubani ohilelekile ekucacisweni, ukuthengwa, ukufakwa, noma ukugcinwa kwemishini yokuvikela umlilo ethembele kulezi zixhumanisi ezamukelwe umhlaba wonke. Ububanzi obuqondile be-bore, ububanzi bangaphandle bomzimba, ububanzi bomjikelezo wezimbambo, ububanzi besihlalo segasket, kanye nesilinganiso sokucindezela yimiphetho emihlanu eyinhloko echaza usayizi ngamunye we-DN, futhi ukuqinisekisa lezi zilinganiso ngokumelene nezidingo zesistimu yakho yisinyathelo sokuqala sokuqinisekisa ukufakwa okuphephile nokusebenzayo. Khumbula ukuthi i-DN iyisibonelo esiqondile, hhayi isilinganiso esiqondile, ngakho-ke hlala ubheka idatha yobuchwepheshe yomkhiqizi ukuze uthole imininingwane eqondile yobukhulu kanye nokubekezelelana okusebenza kumodeli ethile ye-coupling kanye nezinto ezisetshenzisiwe ozicabangayo. Ukuhambisana phakathi kwezinhlobo ezahlukene ze-DN, kanye phakathi kwezixhumanisi ze-Storz neze-threaded, kungafinyelelwa ngokusebenzisa ama-adapter namareducer afanele, atholakala kwa-Varicpand ngezinto ezifanayo namazinga okucindezela njengezixhumanisi eziyisisekelo. Kunoma yiziphi izidingo ezenziwe ngokwezifiso noma izicelo ezikhethekile ezingaphandle kwezinto ezijwayelekile ezikhathalogini, ukuxhumana ne-Varicpand International ngqo kuyindlela ephumelela kakhulu yokuthola isixazululo esihlangabezana nezidingo zakho eziqondile zobukhulu, izinto, kanye nokusebenza ngaphandle kokudela ikhwalithi noma ukuhambisana namakhodi. Imininingwane enikeziwe kulo mhlahlandlela ihloselwe izinjongo zemfundo nokubhekisela, futhi yize kwenziwe konke okusemandleni ukuqinisekisa ukunemba, akufanele isetshenziswe njengesikhundla sokwahlulela kobunjiniyela obuchwepheshe noma ukubonisana nomklami ohlangene wesistimu yokuvikela umlilo. Sicela uvakasheleIkhaya ikhasi noma i-Xhumana Nathi ikhasi ukuze uxhumane nethimba le-Varicpand ukuze uthole usizo olwenziwe ngendlela oyifisayo ngezidingo zakho ze-Storz coupling, okuhlanganisa usayizi wangokwezifiso, ukukhethwa kwezinto, kanye nezinketho zoku-oda eziningi zemiklamo emikhulu.

Lesi sihloko sabhalwa yiqembu lezobuchwepheshe le-Varicpand International ukuze sibe yinsiza yezemfundo esebenzayo kochwepheshe bezokuvikela umlilo, onjiniyela, kanye nabathengi abasebenza ngama-Storz couplings emisebenzini yabo yansuku zonke. Imininingwane yobukhulu kanye nesiqondiso sokusetshenziswa esethulwe lapha kusekelwe ezingeni lomkhakha elamukelwe kabanzi okubandakanya i-NFPA 1963, i-EN 14420, kanye ne-ISO 7241, kodwa amakhodi endawo kanye nezimo zesayithi zingase zidinge izidingo ezengeziwe okufanele ziqinisekiswe unjiniyela wezokuvikela umlilo onelayisensi. I-Varicpand International noma abalobi bayo abathwali cala ngeziphambeko, ukushiywa, noma ukulimala okuvela ekusetshenzisweni kolwazi oluqukethwe kulo mhlahlandlela, futhi kuhlala kungumthwalo womfundi ukuqinisekisa ukuthi noma yiluphi uhlobo lwe-Storz coupling, i-adapter, noma insiza ekhethwe kuhlelo oluthile ihlangabezana nazo zonke izimiso ezisebenzayo zokuphepha, ukusebenza, kanye nemithetho. Sikhuthaza ukuthifunda kabanzi nge-Varicpand Internationalkanye nokuzibophezela kwethu ekukhiqizeni okuseqophelweni eliphezulu, ukuthuthukiswa okuqhubekayo, kanye nenkonzo yamakhasimende emakethe yezokuvikela umlilo kanye neyokuhlanganisa izimboni. Siyabonga ngokuthatha isikhathi sokufunda leli bhukwana eliphelele lemidwebo yamapharamitha, futhi sikufisela impumelelo kuyo yonke imizamo yakho yokuvikela umlilo kanye nokuphatha uketshezi.
