Ukukhetha i-coupling ye-hose yomlilo efanelekile yisinqumo esibalulekile esithinta ngqo ukusebenza kahle nokuphepha kwesistimu yanoma yiluphi uhlelo lokucisha umlilo. Noma ngabe uhlinzeka umnyango womlilo kamasipala, uhlinzeka isitshalo sezimboni, noma ugcina umkhumbi wasolwandle, i-coupling oyikhethayo kufanele ilethe ukuxhumana okuthembekile, okungavuqi ngaphansi kwezimo ezinzima. Ezinye zezindinganiso ezaziwa kakhulu emakethe yomhlaba wonke yemishini yokucisha umlilo yi-GOST coupling ne-Rotta coupling, ngayinye inezimiso ezihlukile zokuklama kanye nezindawo ezithile ezithandwa kakhulu esifundeni. Ukuqonda imininingwane yezobuchwepheshe phakathi kwale mikhaya emibili ye-coupling, ikakhulukazi ngobukhulu obuvame ukucaciswa be-DN50, DN70, ​​ne-DN150, kungaba umehluko phakathi kokusebenza okungenazinkinga nokuhluleka okubizayo kokuhambisana. Lo mhlahlandlela ophelele uhlinzeka ochwepheshe bezokuphepha komlilo, abaphathi bokuthenga, kanye nonjiniyela ngolwazi oluningiliziwe oludingekayo ukuze bahlole zombili izinketho futhi benze isinqumo sokuthenga esinolwazi. Sizohlola ukwakhiwa, izici zokusebenza, nezigameko zokusebenzisa zazo zonke izindinganiso, futhi sinikeze ukuqhathanisa okusebenzayo ngobukhulu ukuze senze lula inqubo yakho yokukhetha.

Ama-coupling amapayipi omlilo we-GOST enzelwe ngokuhambisana namazinga ombuso waseRussia (GOST) futhi asetshenziswa kakhulu e-Eastern Europe, e-Central Asia, nakwezinye izifunda ezihambisana namazinga ezimboni zesikhathi seSoviet. Lawa ma-coupling anohlelo olukhethekile lokuxhuma olusekelwe ekuhlanganisweni kwentambo yomuntu wesilisa nowesifazane ukudala ukuxhumana okuvikelekile, okungangeni manzi. Izintambo ngokuvamile zinkulu futhi ziqine, zivumela ukuqinisa okusheshayo ngesandla noma ngisho noma abacimi bomlilo begqoke amagilavu ​​aqinile, okuyinzuzo enkulu ezimweni eziphuthumayo ezinengcindezi enkulu. Ama-coupling e-GOST enziwa ngezinto ezifana ne-aluminum alloy esezingeni eliphezulu, i-brass, noma i-stainless steel, i-aluminum iyona ekhethwa kakhulu ngenxa yesilinganiso sayo esihle kakhulu samandla kuya esisindo kanye nokumelana nokugqwala kwemvelo. I-DN50 GOST coupling ikhethwa kakhulu emgqeni wokuhlasela nasemapayipini amancane okulethwa, ihlinzeka ngokugeleza okwanele kwemigqa yezandla kanye nama-monitor aphathwayo. Usayizi we-DN70 usebenza njengenketho ephakathi ephakathi yemigqa yokuhlinzeka kanye nokuxhumana kwe-hydrant yezimboni, kulinganisela amandla okugeleza ngesisindo esilawulekayo. Ezingeni eliphezulu, i-DN150 GOST coupling isetshenziselwa ukulethwa kwamanzi okukhulu, njengokuhlinzeka ngemikhumbi yomlilo, izinhlelo ezinkulu ze-hydrant, noma izinhlelo zokudiliza ezindaweni zikagesi. Enye yezici ezichazayo zemiklamo ye-GOST amandla ayo amakhulu emishini, okwenza ibe efanele kakhulu ezindaweni ezidinga kakhulu ezifaka imisebenzi yokumba, izimboni ezisindayo, kanye nokucima umlilo ezindaweni ezibandayo lapho ukuqoqeka kweqhwa ezintanjeni kungaba yinkinga. Iphethini yokuxhuma eyenziwe ngendlela efanayo iqinisekisa ukusebenzisana phakathi kwemishini evela kubakhiqizi abahlukahlukene ngaphakathi kwe-GOST ecosystem, kodwa futhi idala umkhawulo ocacile ohlelweni lokuxhuma olungenawo intambo olusetshenziswa kwezinye izingxenye zomhlaba.

Ama-coupling ombhobho womlilo we-Rotta, owaziwa futhi kwezinye izimakethe ngokuthi "Rotta" noma ama-coupling "waseJalimane", amele indlela ehlukile yobunjiniyela eyasuka e-Central Europe futhi yathola ukwamukelwa kabanzi e-Western Europe, eMiddle East, nasezingxenyeni zase-Afrika nase-Asia. Ngokungafani nesistimu ye-GOST enezintambo, ama-coupling e-Rotta asebenzisa indlela yokukhiya yohlobo lwe-bayonet evumela ukuxhuma nokukhipha ngokushesha kakhulu ngaphandle kokudinga amathuluzi. Umklamo uhlanganisa izimbambo ezimbili ezilinganayo ohlangothini olulodwa lwe-coupling ezibandakanya nezindawo ezihambisanayo ohlangothini oluhlangene, futhi ukujikeleza okukodwa okulula kukhiya umhlangano endaweni ngokuchofoza okuzwakala. Lejubane lokusebenza liyinzuzo enkulu yamasu ekucimeni umlilo, lapho imizuzwana ngayinye ibalulekile, futhi futhi kunciphisa umthwalo womzimba kubasebenzi okufanele benze ukuxhumana okuningi ngesikhathi senhlekelele enkulu. Ama-coupling e-Rotta atholakala ngobukhulu obufanayo obujwayelekile—i-DN50, i-DN70, ne-DN150—futhi avame ukwenziwa kusuka kuma-aluminium alloys alula, ithusi, noma insimbi engagqwali, kuye ngokumelana nokugqwala okudingekayo nesilinganiso sokucindezela. I-DN50 Rotta coupling isetshenziswa kabanzi kumaloli we-foam, imilomo yezandla, nemigqa yokuhlasela emfushane ekucimeni umlilo ezakhiweni. Usayizi we-DN70 ungase ube ububanzi obuphakathi obudume kakhulu ekucimeni umlilo emadolobheni, okunikeza isivumelwano esihle phakathi kokulawuleka nokugeleza kwevolumetric kokubili imisebenzi yokuhlinzeka nokuhlasela. I-DN150 Rotta coupling isetshenziswa ezinhlelweni ezinokugeleza okuphezulu njengezithuthuthu zokushisa ezindizeni, ama-monitor amakhulu, nezinhlelo zokucisha umlilo ezakhiweni ezinkulu noma ezindaweni zokugcina izimpahla. Enye yezici ezivelele zesistimu ye-Rotta umklamo wayo ojwayelekile we-gasket, ohlanganisa ngokuphumelelayo ngaphansi kwezinhlobonhlobo ezibanzi zokucindezela futhi uhlala usebenza noma ngabe izindawo ezihlangene zincane kancane noma zinokungcola. Indlela ye-bayonet iphinde imelane nokukhipha ngengozi ngenxa yokudlidliza, okwenza ama-coupling e-Rotta abe ukukhetha okuqinile kokuxhumana kwamaphampu kanye nezinto zokusebenza lapho kukhona ukushaqeka komshini.

Umehluko obaluleke kakhulu phakathi kwezixhumi zomlilo ze-GOST neze-Rotta ungukuthi zixhunywa kanjani—ezinye zisebenzisa intambo kanti ezinye zisebenzisa indlela yokujikijela—lokhu kuthinta isivinini sokusebenzisa, ukuthembeka komshini, kanye nokuhambisana nezinto ezikhona. Izixhumi ze-GOST zidinga umsebenzisi ukuthi ajike intambo yesilisa esikhwameni sowesifazane, inqubo ethatha amasekhondi ambalwa isikhathi eside ukuxhuma ngalunye kodwa enikeza ukuxhumana okuqinile, okumelana nokudlidliza okungenzeka kungaphumi lapho kunesivinini. Izixhumi ze-Rotta, ngokuphambene, zingaxhunywa ngaphansi kwamasekhondi amabili ngokujikijela okulula, okuzenza zibe ngcono ezimeni zokuthunyelwa ngokushesha lapho izindebe eziningi zomlilo kumele zixhunywe ngokushesha. Izindinganiso zentambo nazo ziyahlukahluka kakhulu: i-GOST isebenzisa iphrofayili yentambo ebanzi, enomumo othambekayo eyenzelwe indinganiso yaseRussia i-GOST, kanti izixhumi ze-Rotta zisebenzisa ukuxhumana okubushelelezi, okusekelwe kumalokhi ngaphandle kwezintambo nhlobo, okusho ukuthi lezi zinhlelo ezimbili azihambisani ngomshini ngaphandle kwama-adaptha akhethekile. Izilinganiso zengcindezi ngokuvamile ziyalinganiswa kuzo zombili izinhlobo ezithile zezinto ezisetshenzisiwe nosayizi, nezingcindezi ezijwayelekile zokusebenza ezisukela ku-10 kuye ku-25 bar ezinguqulweni ezijwayelekile ze-aluminium kanye nokuba phezulu kwezinguqulo zethusi noma zensimbi engagqwali. Ukukhetha izifunda kuthinta kakhulu ukwamukelwa kwemakethe: i-GOST ibusa eRussia, Ukraine, Kazakhstan, kanye namanye amazwe e-CIS lapho izindinganiso zikazwelonke zidinga ukusetshenziswa kwayo, kanti i-Rotta iyindlela ekhethwayo eJalimane, Austria, Netherlands, kanye namazwe amaningi aseMiddle East alandela imithetho yaseYurophu. Ngokuqondene nokugcinwa, izintambo ze-GOST zingaba sengcupheni yokuguguleka uma ziqiniswa kakhulu noma uma udoti uqoqana ezintanjeni, zidinga ukuhlanjululwa nokugcotshwa njalo ukuze kuqinisekiswe ukusebenza okubushelelezi. Amalokhi e-bayonet e-Rotta ancishwe amathuba okuguga komshini kodwa indlela yokukhiya ingavinjelwa ukungcola noma ukubanda, ngakho-ke ukuhlola njalo iziteshi zamalokhi nendawo ye-gasket kubalulekile. Izindleko zokwakha ziyefana, izintengo ziholwa ikakhulukazi ukukhethwa kwezinto zokusetshenziswa kanye nokubekezelelana kokukhiqiza kunokuthi uhlobo lwesixhumi uqobo. Lapho kuhlolwa izindleko zokuba nazo isikhathi eside, izinhlangano kumele zicabangele ukutholakala kwezingxenye zokushintsha kanye nabasebenzi abaqeqeshiwe—izinhlelo ze-GOST zingaba nzima ukuzithola ngaphandle kwe-Eastern Europe, kanti izingxenye ze-Rotta zitholakala kabanzi kubahlinzeki bezixhumi zezimboni zomhlaba wonke.

Ukukhetha ububanzi obufanele benayiphu ye-coupling yomlilo kuyindaba yokufanisa usayizi we-coupling nombhobho we-hose, izinga lokugeleza elidingekayo, kanye nomfutho wesistimu, futhi lesi sinqumo asihlobene nokuthi ukhetha imiklamo ye-GOST noma ye-Rotta. I-DN50 coupling, kungakhathaliseki ukuthi iyiphi indinganiso, ihambisana nama-hose anobubanzi bangaphakathi obungaba amamilimitha angu-50 futhi ngokuvamile ilinganiselwe ukugeleza kufika kumalitha angu-400 ngomzuzu kumishini emaphakathi, okuyenza ilungele izintambo zezandla, ama-reel okubuyisela emuva, nama-hose amancane wehlathi. Kokubili izilungiselelo ze-GOST neze-Rotta, usayizi we-DN50 awusindi futhi kulula ukuphatha, nge-aluminum coupling enesisindo esingaba amagremu angu-300 kuye ku-400 ingxenye ngayinye. I-DN70 coupling, efakwa kuma-hose obubanzi obungamamitha angu-70, ububanzi bomsebenzi wokulwa nomlilo ezakhiweni kanye nokuvikelwa komlilo ezimbonini, isekela amazinga okugeleza kusuka kumalitha angu-800 kuye ku-1,200 ngomzuzu kuye ngomshini nobude be-hose. I-DN70 GOST coupling inobubanzi bangaphandle bokuxhuma obungaba amamilimitha angu-85 kanye ne-pitch yokuxhuma eyenzelwe ukuxhuma ngokushesha, kanti i-DN70 Rotta coupling isebenzisa ama-lugs ahlukaniswe ngo-90 degrees anomgwaqo wangaphakathi ocacile ongamamilimitha angu-65 ukuze kuncishiswe ukukhawulwa kokugeleza. Usayizi we-DN150 umele isiphetho esinzima kakhulu, esenzelwe ama-hose amakhulu-bhore noma ukuxhumana okuqondile kwe-hydrant okumele kube ngaphezu kwamalitha angu-3,000 ngomzuzu ezinhlelweni ezinkulu zokucisha umlilo. I-DN150 GOST couplings ifaka izilinganiso ezinkulu zokuxhuma—ezivame ukudlula amamilimitha angu-170 ebubanzi bangaphandle—futhi ngokuvamile yenziwa ngobhedu noma insimbi engagqwali ukuze imelane nezingcindezi zemishini zezindawo ezinokugeleza okuphezulu, ezinezingcindezi eziphakeme. I-DN150 Rotta couplings nayo isebenzisa ama-bayonet lugs amakhulu kanye namabhande angemuva aqiniswe ukuze abambe amandla akhishwe ama-hose amakhulu-ububanzi kanye nama-monitor nozzles. Lapho kuqhathaniswa izilinganiso phakathi kwe-GOST ne-Rotta ngosayizi ofanayo, kubalulekile ukuqaphela ukuthi ububanzi bangaphandle obuphelele kanye nobude bokuxhuma bungahluka ngamamitha ambalwa, okungadala ukuphazamiseka nama-hose clamps akhona, ama-bracket okugcina, noma ama-adapters. Umthamo wokugeleza unqunywa kakhulu ububanzi bangaphakathi kunohlobo lwe-coupling, ngakho-ke i-DN70 GOST ne-DN70 Rotta coupling izohlinzeka ngokusebenza okufanayo kwe-hydraulic ku-hose efanayo nobude nomshini. Kodwa-ke, ukwehla komshini ku-coupling ngokwayo kungahluka kancane ngenxa yomehluko wezinto zangaphakathi—imiklamo ye-Rotta ngokuvamile inenguquko ye-bore ebushelelayo, kanti izixhumi ze-GOST zingadala ukuhlukumezeka okuncane lapho kuxhunywa khona. Ngalesi sizathu, onjiniyela abaklaya izinhlelo ezinokugeleza okuphezulu ezinezibhajethi eziqinile zomshini kufanele bacela idatha enemininingwane ye-flow coefficient kumkhiqizi kunokuthembela kuphela osayizi.

Ukukhetha phakathi kwezixhumi zamapayipi omlilo i-GOST ne-Rotta kuhlelo oluthile kufuna ukuhlola okuhlelekile kwezimfuno zengcindezi yesistimu, ukuhambisana nohlobo lwephayipi, ingqalasizinda ekhona yezinto zokusebenza, kanye namazinga omthetho alawula isifunda sokusebenza. Into yokuqala nesibaluleke kakhulu yingcindezi yokusebenza yesistimu yakho yokucisha umlilo—zombili izixhumi ze-GOST ne-Rotta zitholakala ngezinhlobonhlobo ezilinganiselwe ingcindezi, kodwa kufanele uqinisekise ukuthi ingcindezi eqhumayo elinganiselwe yesixhumi idlula ingcindezi ephezulu yesistimu ngesici sokuphepha esivame ukuba yi-3:1 noma ngaphezulu ngokwendlela yakho yendawo. Okulandelayo, hlola iphayipi ohlose ukulisebenzisa: isixhumi kufanele sihambisane ngokunembayo nodimitha wangaphakathi wephayipi (DN50, DN70, noma DN150) futhi sihambisane nobunzima bodonga lwephayipi kanye nezinto ezisetshenzisiwe, njengoba amanye amapayipi enziwe ngemishini adinga izixhumi ezine-shank ende noma iphrofayili ehlukile ye-barb ukuze kufezeke ukuxhunywa okuqinile okuboshiwe noma okuboshwe. Ukuhambisana nezinto zokusebenza ezikhona kuvame ukuba yisici esinqumayo—uma isiteshi sakho somlilo, isitshalo sezimboni, noma umkhumbi wakho wasolwandle usunengxenye enkulu yamapayipi, ama-nozzle, ama-valve e-hydrant, nama-adapter enye indinganiso, ukushintshela kwenye indinganiso kuzodinga ukuthengwa kwama-adapter noma ukufakwa esikhundleni ngokuphelele isitokwe esikhona, okungaba kubiza kakhulu. Izinga lendawo kanye nezinqubomgomo zokuthenga azikwazi ukunganakwa: imisebenzi eminingi yomlilo kazwelonke imisa uhlobo oluthile lwesixhumi kuyo yonke imishini kamasipala ukuze kuqinisekiswe ukusebenza ndawonye phakathi nezimpendulo zosizo oluhlangene, futhi ukwephula lezi zingqikithi kungadala izinkinga zokubopha. Izimo zemvelo ezifana neqhwa elibi kakhulu, ukuchayeka emanzini anosawoti, noma uthuli oluklabayo kufanele kuthinte ukukhethwa kwezinto ezisetshenzisiwe—i-aluminium ilula futhi iyonga kakhulu ezinhlelweni eziningi zasendlini nasemadolobheni, kanti i-brass noma i-stainless steel iyatuswa ezindaweni zasolwandle, zamakhemikhali, noma ezishisa kakhulu lapho ukumelana nokugqwala kubaluleke kakhulu. Ukulula kokuqeqesha nakho kubalulekile: abacimi bomlilo namaqembu ezokuphepha ezimbonini kufanele akwazi ukusebenzisa izixhumi ngokuzenzekelayo lapho kunesimo esicindezelayo, ngakho-ke uma abasebenzi bakho sebeqeqeshiwe ngohlelo lwe-bayonet lwe-Rotta, ukushintshela ku-GOST enezintambo kungadala ukudideka nokubambezeleka ezikhathini ezibalulekile. Ekugcineni, cabanga ngesiteshi sokuhlinzekwa esesikhathini eside—uma inhlangano yakho isebenza emhlabeni wonke noma ithenga izinto ezivela kubahlinzeki abaningi, ukutholakala kwezixhumi ezishintshwayo, ama-gaskets, nezingxenye zokulungisa kufanele kuthinte ukukhetha kwakho. I-Varicpand International inikeza uhla olubanzi lwezixhumi ze-GOST ne-Rotta kuzo zonke izinhlobo ezintathu ezibalulekile, kanye nesiqondiso sobuchwepheshe ukukusiza ukhethe umkhiqizo ofanele kumongo wakho wokusebenza.

I-Varicpand International izibeke njengomphakeli omethembayo wezinto zokucisha umlilo ezisezingeni eliphezulu, okuhlanganisa neqoqo eligcwele lama-coupling ombhobho womlilo we-GOST ne-Rotta ngosayizi be-DN50, DN70, ​​ne-DN150. Izinqubo zethu zokukhiqiza zilandela amazinga aqinile okulawula ikhwalithi, ziqinisekisa ukuthi yonke i-coupling ihlangabezana noma idlula izidingo zemishini nezingcindezi zemigomo yamazwe omhlaba efanele. Siyakuqonda ukuthi ochwepheshe bokuphepha komlilo badinga izingxenye abangazithembela ezimeni zokuphila nokufa, yingakho sisebenzisa kuphela izinto zokusetshenziswa ezisezingeni eliphezulu—ama-aluminum alloys acindezelweyo anokuqina okufakazelwe, ithusi elingenalo i-lead-free ezicelo zamanzi okuphuza, namabanga ensimbi engagqwali ayimelana nokugqwala ezindaweni ezidinga kakhulu.
