Ukukhetha i-coupling efanele yempahla yomlilo akuyona nje indaba yokulula; kuyisinqumo esibalulekile esithinta ngqo ukuphepha, ukusebenza kahle, nokwethenjwa kwemisebenzi yokucisha umlilo. Ama-coupling wezinyoka zomlilo asebenza njengezindawo zokuxhuma ezibalulekile phakathi kwezinyoka, amaphampu, ama-hydrant, nama-nozzle, nanoma yikuphi ukungafani noma ukwehluleka kulezi zindawo kungaholela ukuvuza, ukwehla kwengcindezi, noma ukuphuka okubulalayo ngesikhathi esiphuthumayo. Njengoba imboni yomhlaba wonke yokuphepha umlilo ithembele ezindinganisweni eziningana ezihlukene zama-coupling, ukuqonda umehluko phakathi kwezinhlelo ezimbili ezivame kakhulu—i-GOST ne-Rotta (evame ukubizwa nge-Storz)—kuba kubalulekile kubaphathi bokuthenga, abaphathi bomlilo, nabasabalalisi bemishini ngokufanayo. Lo mhlahlandlela ophelele uzohlola izici ezichazayo zama-coupling we-GOST ne-Rotta, uqhathanise izici zawo zemishini nezinto ezibonakalayo, futhi unikeze izindlela ezicacile zokukhetha ezisekelwe ohlotsheni lwemishini, izidingo zengcindezi, kanye nendawo yokusebenza. Ekupheleni kwalesi sihloko, uzoba nolwazi oludingekayo ukuze wenze izinqumo ezinolwazi, ezizobhekana nekusasa, zezidingo zakho zokuxhuma izinyoka zomlilo, uqinisekise ukuthi yonke i-coupling oyisebenzisayo yenza kahle kakhulu ngaphansi kwezimo ezinzima kakhulu. Ochwepheshe bokucisha umlilo bayakuqonda ukuthi ukuxhunywa okunamandla kwezinyoka zomlilo kuyisisekelo somzamo wokucisha noma yimuphi umlilo, futhi ukukhetha phakathi kwama-coupling anezintambo kanye nalawo asebenzisa i-bayonet kungachaza isivinini nempumelelo yokuphazamisa.

I-GOST couplings ibizwa ngegama lesikhungo se-Russian (Gosudarstvennyy Standart) elilawula ukuklama kwazo, usayizi, nezidingo zokusebenza, futhi imele uhlobo oluphambili lwe-coupling e-Russia, e-Commonwealth of Independent States, nasezimakethe eziningi zaseMpumalanga Europe. Lezi zixhumi zisebenzisa indlela yokuxhuma enezintambo, edinga ukuthi izingxenye zamadoda nezabesifazane zixhunywe ndawonye ngesandla noma ngosizo lwe-spanner, kudala ukuvalwa okuqinile nokuphephile okungavumeli ukuhoxiswa okungafanele. Ukuklama okunezintambo kwe-GOST fire hose couplings kuqinisekisa ukuvalwa kwemishini okungamelana nengcindezi ephezulu, okujwayelekile okulinganiselwa emgqeni wokusebenza phakathi kuka-1.0 MPa no-1.6 MPa kuye ngestandadi ye-GOST ethile kanye nekhwalithi yezinto, okwenza kube kufanelekile kokubili izinhlelo zokulwa nomlilo eziphansi neziphakeme. Lezi zixhumi ngokuvamile zenziwa ngensimbi ye-aluminium, brass, noma insimbi engagqwali, lapho okuguquguqukayo kwe-aluminium kunikeza ubudlelwano obuhle bokuphakama-kokuphakama obunciphisa ukukhathala kwababheki bomlilo abadinga ukuthwala nokuxhuma ama-hoses ngokushesha endaweni. Ngokuphathelene nezicelo, i-GOST couplings isetshenziswa kabanzi ezimotweni zomlilo zedolobha, ezinhlelweni zokunciphisa umlilo zezimboni, ezixhunywe kumahydrant, nasezinhlelweni ezinkulu zokulethwa kwamanzi lapho ukwethembeka ngaphansi kwengcindezi ephezulu okuqhubekayo kungavumelani. I-pitch ye-thread ne-diameter eyakhiwe yi-GOST iqinisekisa ukufaniswa okuphelele phakathi kwezithako ezikhiqizwe abakhiqizi abahlukene, okwenza kube lula ukuhamba kwezimpahla nokuthengwa kwezinto ezithathelwana ezindaweni zomlilo ezindaweni ezinkulu. Ngaphezu kwalokho, ubunjalo obuqinile bezixhumi ezinezinhlamvu zenze kube kuhle ezindaweni lapho ama-hoses angase abhekane nokuphathwa okungafanele, izinga lokushisa eliphakeme, noma ukuvezwa kumakhemikhali, njengoba izintambo zensimbi zingakwazi ukumelana nokuhlukumezeka okukhulu ngaphandle kokulahlekelwa amandla azo okuvalwa.

Ngaphandle kwezinzuzo zazo eziningi, izixhumi ze-GOST zidinga ukulungiswa ngokucophelela lapho zixhunywa ukuze kugwenywe ukuxhuma okungalungile, futhi inqubo yokuzikhiya ingase ibe kancane kancane uma iqhathaniswa nezinhlelo zokujika okwesikhashana, okuyinto ekhuthaze ukuthuthukiswa kwezindinganiso ezihlukahlukene zezixhumi. Amaqembu ezicishamlilo asebenza ezindaweni ezibandayo kakhulu avame ukukhetha izixhumi ze-GOST ngoba imishini enezintambo ayinakho ukuvaleka kalula lapho iqhwa noma udoti uqoqana ezindaweni ezihlangana, inqobo nje uma izintambo zigcinwa zihlanzekile futhi zigcotshwe kancane. Izinga le-GOST lihlanganisa osayizi abaningi, ngobubanzi obuvame kakhulu obungu-50 mm, 65 mm, 70 mm, 80 mm, kanye no-100 mm, okuvumela iminyango yomlilo ukuthi ilingane usayizi wesixhumi ngokunembayo nobubanzi bepayipi nezidingo zokugeleza. Lapho uthenga izixhumi ze-GOST, abathengi kumele banake ispecification yempahla ngoba izixhumi ze-aluminium, nakuba zilula, zingase zibonise ukugqwala kwe-galvanic lapho zixhunywa nezinsimbi ezihlukahlukene emanzini; izinhlobo zobhedu ne-stainless steel ziqeda le nkinga. Izindinganiso eziningi zomlilo zase-Eastern Europe zisadinga ukusetshenziswa kwezixhumi ze-GOST ezinamathambo azo zonke izinto zikagesi zomlilo kamasipala, okudala imakethe enkulu yesibili yalezi zingxenye njengoba imikhumbi endala ibuyekezwa noma yandiswa. Sekukonke, izixhumi ze-GOST zinikeza ubuqotho obukhulu bokubopha kanye namandla omshini, okwenza zibe isixazululo esihloliwe sesikhathi sokuxhuma amapayipi omlilo ezifundeni lapho izindinganiso ezinamathambo sezilokhu zikhona amashumi eminyaka.

Ama-coupling akwa-Rotta, aziwa kabanzi emhlabeni wonke njengama-coupling akwa-Storz, asebenzisa ukuxhumana okufanayo kwesitayela sebhayonethi okwenza ukuthi axhumane futhi ahlukane ngokushesha ngokunyakaza okukodwa kwesigamu sokujikeleza, okuqeda isidingo sezintambo ngokuphelele. Lo mklamo unezinhlangothi ezimbili ezifanayo—ngalinye lihlome ngezimbambo nezingxenye ezihlangana lapho lijikeleza—ngakho-ke akukho ukuhlukaniswa kwendoda noma owesifazane, okusho ukuthi noma yimaphi ama-coupling amabili akwa-Rotta angahlanganiswa ngaphandle kokufuna okufanayo. Uhlelo lwe-Storz lwaqala eJalimane futhi selwamukelwe njengendlela ejwayelekile yokuxhuma imibhobho yomlilo ezingxenyeni eziningi zaseNtshonalanga Yurophu, eNyakatho Melika, e-Australia, nasezingxenyeni eziningi zase-Asia naseMiddle East, ikakhulukazi ngenxa yobuchwepheshe bayo bokuxhuma nokusebenza kwayo okulula. Lawa ma-coupling avame ukulinganiswa ngamapayipi okusebenza kusuka ku-1.0 MPa kuya ku-2.5 MPa, nezinguqulo eziphakeme ezikwazi ukubhekana nemithwalo emikhulu, ngenxa ye-geometry yezimbambo eqinile kanye ne-gasket yokubopha evame ukucindezela nxazonke. Ama-coupling akwa-Rotta enziwa ngohlu olufanayo lwezinto ezifana nama-coupling akwa-GOST—i-aluminium, i-brass, ne-stainless steel—kodwa indlela yebhayonethi ibeka ingcindezi ehlukile ezimbambeni, idinga ukusakazwa okunembayo noma ukucubungula ukuze kuqinisekiswe ukukhiya okungaguquguquki nokuvimbela ukuguguleka ngokusebenzisa kaningana. Isicelo esiyinhloko sama-coupling emibhobho yomlilo akwa-Rotta sisezigamekweni lapho yonke imizuzwana ibalulekile, njengokulwa nomlilo ezakhiweni, ukucisha imililo yasendle, kanye nezenzo zokuhlasela ezisheshayo, ngoba ukuxhumana kwesigamu sokujikeleza kungonga isikhathi esibalulekile phakathi nemijikelezo yokufaka nokukhipha imibhobho. Ngaphezu kwezibopho ezijwayelekile zokulwa nomlilo, ama-coupling akwa-Rotta asebenzisa kabanzi ezinhlelweni zokuvikela umlilo zezimboni, imibhobho yomlilo yasolwandle, amaloli okucisha umlilo ezindizeni, kanye nezinguqulo eziphakeme lapho izici zokuxhuma/ukukhipha ezisheshayo zithuthukisa ukuguquguquka kwezinto.

Ukwakheka okufanayo kwezixhumi zeRotta kwenza lula ukuphathwa kwezinto zesitokwe ngoba izicishamlilo azidingi ukugcina izinhlangothi zazo zesilisa nezowesifazane ngokwehlukana, futhi ukungabi khona kwezintambo kusho ukuthi akukho mng risk wokuxhuma izintambo ngokungalungile noma ukulimaza izintambo ezingenza isixhumi singasebenzi. Izixhumi zeRotta zisekelwe ku-gasket engashintshwa—evame ukwenziwa nge-EPDM, i-NBR, noma irabha ye-silicone—enikeza isitembu esingangeni manzi, futhi le gasket ingashintshwa ngokushesha lapho iguga noma ingcola, okwandisa impilo yesevisi yomzimba wesixhumi. Okubalulekile okukodwa okufanele kucatshangelwe ngezi xhumi zeRotta ukuthi ama-bayonet lugs angaguga ngokuhamba kwesikhathi, ikakhulukazi uma izixhumi zixhunywa njalo ngaphansi kokungahlangani okuphezulu noma uma udoti uqoqana ezindaweni zama-lug, okuholela ekulinganeni okuxegayo nokuphuma kwamanzi okungenzeka. Ukubhekana nalokhu, izixhumi zeRotta ezisezingeni eliphezulu zihlanganisa ama-lug inserts aqinisiwe noma imicengezi yokuguga yensimbi engagqwali eyandisa kakhulu impilo yesekhondi futhi igcina amandla okukhiya avamile ngisho nangemva kwezinkulungwane zokuxhuma. Ezicishamlilo ezisebenza ezindaweni eziningi noma ezihlala zisebenzisana nezinkampani eziseduze, ukwamukelwa kwezi xhumi zeRotta emhlabeni wonke kuqinisekisa ukusebenza okungenamihlangano ngaphandle kwesidingo sama-adapters noma ukuqeqeshwa okukhethekile. Umkhuba womhlaba wonke wokumisa iphrofayela yeStorz uye wanda eminyakeni yamuva nje, ngezwezizwe eziningi ezazisebenzisa izinhlelo zezintambo manje sezivuma noma ngisho ziphoqa iRotta ezintweni ezintsha zikagesi zomlilo njengengxenye yemizamo ebanzi yokwenza kube sesimanje.

Umehluko obaluleke kakhulu phakathi kwezixhumi ze-GOST neze-Rotta usemekanisimeni yazo yokuxhuma: i-GOST isebenzisa isixhumi esiyisikrufu (uhlobo lwesikrufu) esidinga ukuhambisana ngokujikeleza namajikajika amaningi ukuze kufezeke uphawu oluqinile, kanti i-Rotta yona isebenzisa uhlelo lwe-bayonet (ikota yokujikeleza) olukhiya ngokushesha ngokujikeleza okulula okungu-90 degrees. Ngokombono wezinto ezisetshenzisiwe, zombili izinhlobo zezixhumi zitholakala nge-aluminium, ithusi, ne-stainless steel, kodwa i-geometry yomklamo isho ukuthi izixhumi ze-Rotta ze-aluminium zingase zibone ukuguga okusheshayo kwezinduku kunezikrufu ze-GOST ze-aluminium ngaphansi kwezimo ezifanayo zokusebenzisa, ngoba izinduku ze-bayonet zigxilisa ingcindezi ezindaweni ezincane zokuxhumana. Izilinganiso zengcindezi zihambisana kakhulu—izixhumi eziningi ze-GOST neze-Rotta zilinganiswe ingcindezi yokusebenza kusuka ku-1.0 MPa kuya ku-1.6 MPa—kodwa izinhlobo eziphezulu ze-Rotta zingadlula ku-2.5 MPa, okwenza zibe yisinqumo esikhethwayo ezinhlelweni zomlilo eziphezulu njengezisekelwa ezakhiweni eziphakeme noma ezinhlelweni zokuhlanganisa i-foam ezimbonini. Ukuhambisana kuyinto ebalulekile esebenza kakhulu: izixhumi ze-GOST neze-Rotta azihambisani ngomshini ngaphandle komshini wokuxhuma, ngakho-ke iminyango yomlilo esebenza ezindaweni lapho kukhona khona zombili izindinganiso kufanele iphathe imishini yokuxhuma enikezelwe noma igcine imigqa yamapayipi ehlukene yohlelo ngalunye. Izixhumi eziyisikrufu njenge-GOST zinikeza ukuxhumana okumelana nokudlidliza okungase kungalokothi kuxegxe ngokuhamba kwesikhathi ezinhlelweni ezinokugeleza okuphezulu noma ingcindezi ephazamisayo, kanti izixhumi ze-bayonet njenge-Rotta ngezinye izikhathi zingakwazi ukuhoxa kancane uma umekanismu wokukhiya ungahlali kahle noma uma i-gasket icindezela ngokungalingani. Ukusebenza kwezinga lokushisa nakho kuyahluka: ezindaweni ezingaphansi kweqhwa, umswakama ezikrufweni ze-GOST ungaba yiqhwa futhi wenze kube nzima ukukhipha, kanti izixhumi ze-Rotta, ezinezindawo zazo zangaphandle ezibushelelezi kanye nezindawo ezimbalwa ezincane, kulula kancane ukuzikhipha ngemuva kokuchayeka ebandeni, yize ukuqoqeka kweqhwa emaphaketheni ezinduku kusengabeka izinselele.

Umehluko omunye obalulekile uhilela isimiso sokubopha: izixhumi ze-GOST ngokuvamile zibopha ngoxhumana naye wensimbi-kuya-ensimbi noma inhlanganisela ye-gasket yerabha nokucindezelwa kwentambo, kanti izixhumi ze-Rotta zisebenzisa kuphela i-gasket ecindezelwe ehlezi emgqeni ebusweni bohlangothi ngalunye. Lokhu kusho ukuthi izixhumi ze-Rotta zidinga ukuhlolwa nokushintshwa kwe-gasket ngezikhathi ezithile—umsebenzi olula wokugcinwa—kanti izixhumi ze-GOST zingadinga ukuhlanjululwa kwentambo nokwelashwa kwe-anti-seize ukugcina ukusebenza kwazo kokubopha emashumini eminyaka. Ngokuya ngezici zokugeleza, izinhlobo zombili zezixhumi, lapho zilinganiswe kahle, zethula ukulahleka komfutho okuncane, kodwa i-geometry yangaphakathi ingahluka kancane, nezinye izinhlobo ze-GOST ezine-reduction ephawulekayo endaweni yentambo engandisa ukudideka ezingeni eliphezulu kakhulu lokugeleza. Ngokombono wezindleko, izixhumi ezijwayelekile ze-GOST ne-Rotta ze-aluminium zinezindleko ezifanayo, kodwa izinto ezikhethekile (ithusi, insimbi engagqwali) noma izilinganiso zokucindezela ezenziwe ngokwezifiso zingabangela ukuthi amanani ahlukane ngokusekelwe ebunzini bokukhiqiza kanye nevolumu. Imicengezi yomlilo egxila ekusebenzeni ndawonye nezinye izinhlangano eziseduze nabahlinzeki bamazwe ngamazwe izodonselwa ku-Rotta, kanti lezo ezisebenza ezimakethe ezibusa nge-GOST zizokhetha ngokwemvelo izixhumi ezintambo ukuze zigcine ukuhambisana nama-hydrant nemishini ekhona. Ukuqonda lemihluko eyisisekelo—intambo ngokumelene ne-bayonet, ukukhethwa kwezinto, isikhundla sokucindezela, kanye nendlela yokubopha—kungukuqala kokwenza isinqumo sokuthenga esinolwazi esilinganisa isivinini, ukuphepha, nokugcinwa kwesikhathi eside kunoma yisiphi isicelo sokuxhuma komlilo.

Ukukhetha phakathi kwezixhumi ze-GOST neze-Rotta zemishini yomlilo kuqala ngokuhlola ngokucophelela imvelo yokusebenza, okuhlanganisa izinga lokushisa elivamile endaweni, ukuchayeka kumakhemikhali noma emanzini olwandle, kanye nezingcindezi zemishini izobhekana nazo izivunguvungu zombili ekuqeqeshweni nasezimo ezingalindelekile zangempela. Emalungwini omlilo omkhandlu asebenza ikakhulukazi ezindaweni zasemadolobheni anezindawo ezijwayelekile zokuxhuma amanzi, ingqalasizinda yendawo ekhona izothonya kakhulu isinqumo: uma isifunda sisebenzise izixhumi zokubopha ze-GOST emlandweni, ukwamukela i-Rotta kungadinga uhlelo lokuguqula olubizayo oluhlanganisa ama-adaptha noma ukuguqulwa kwezindawo zokuxhuma amanzi. Izidingo zengcindezi zimelela isici sesibili esibalulekile sokukhetha: ukulwa nomlilo ezakhiweni eziphakeme kanye nezinzuzo zezimboni ezidinga ingcindezi yokusebenza engaphezu kuka-1.6 MPa kufanele zibheke ezixhuni ze-Rotta eziklanyelwe ngokukhethekile insizakalo yengcindezi ephezulu, njengoba umklamo we-bayonet ungabhekana nemithwalo ephakeme ngokufanele ngento efanele nokucaciswa kwe-gasket. Ukuphindaphinda kokuxhuma nokukhipha izivunguvungu kungenye into ebalulekile; iminyango eyenza imidlalo yokuhlasela esheshayo noma imisebenzi yomlilo wehlathi lapho izivunguvungu zixhunywa futhi zikhiwa njalo izozuza kakhulu ngejubane lesekhondi elilodwa lezixhumi ze-Rotta, kanti iziteshi ezinokubeka izivunguvungu ezizinzile zingathola izindleko eziphansi nokwethembeka okufakazelwe kwezixhumi ze-GOST ngokwanele. Ukuhambisana nezimpahla ezikhona zemikhumbi, okuhlanganisa amaphampu, imilomo, abaqaphi, nezivunguvungu zokudonsa, kufanele kuhlolwe ngokucophelela ngoba ukuxuba izinhlobo zezixhumi kuwo wonke umugqa owodwa wezivunguvungu kudala amaphuzu abuthakathaka futhi kudinga ama-adaptha angeziwe engeza isisindo kanye nezindawo ezingase zivuze. Izimo zemvelo ezifana nokuchayeka otshanini, udaka, noma ukudlula kwamakhemikhali kungasheshisa ukuguga kumalugu e-bayonet nama-gasket, okubonisa ukuthi izixhumi zokubopha ze-GOST zingase zinikeze ukuqina okukhulu ezindaweni ezingcolile kakhulu noma ezihlikihlayo lapho imfucumfucu ingavala izindawo zamalugu futhi ivimbele ukukhiya okufanele.

Iminyango yomlilo esebenza ezindaweni eziningi noma evame ukubambisana ngokuzenzakalelayo kufanele icabange kakhulu ngokusebenzisa izixhumi ze-Rotta, njengoba lolu hlelo lwamukelwa cishe yonke indawo ezimakethe ezithuthukile zomlilo ngaphandle kwezindawo ezaziyingxenye yeSoviet Union. Izindleko zezimali zidlula intengo yokuqala yokuthenga: ukuhlaziywa kwezindleko zokusebenza kufanele kufake izikhathi zokushintsha izimpawu, izinto zokugcina izintambo, izinto zokuhlanganisa, kanye nesikhathi somsebenzi esidingekayo sokuxhuma nokunqamula phakathi kwemikhuba nezehlakalo. Kwamaqembu okuvikela umlilo ezimbonini okufanele ahambisane nezinhlelo zamanzi ezikhona esitshalweni, isinqumo singase sinqunywe ngohlobo lwesixhumi esivele sifakiwe kuma-hydrants, kuma-standpipes, naku-monitors angashintshi; ukubuyekeza isikhungo sonke kwisistimu ehlukile kungaba yindleko kakhulu. Izidingo zokuqeqesha nazo ziyahlukahluka: ngenkathi izinhlobo zombili zezixhumi kulula ukuzifundisa, inkumbulo yemisipha yokusebenza kwe-quarter-turn bayonet ivame ukutholwa ngokushesha kunokulungiswa ngokucophelela nokulawulwa kwamandla adingekayo ezixhumanisweni ezintambo, kunciphisa amathuba amaphutha okuxhuma ngaphansi kwengcindezi. Ngokuhlola ngendlela eyihle lezi zindlela zokukhetha—izindinganiso zendawo, isigaba sokucindezela, imvamisa yokuxhuma, imvelo, ukusebenza ndawonye, izindleko zokusebenza, kanye nokulula kokuqeqesha—abathengi bezinto zomlilo bangakhetha ngokuzethemba uhlelo lwezixhumi oluletha ukuxhunywa komlilo okuphephe kakhulu, okunempumelelo kakhulu, futhi okonga kakhulu ngokuya ngezindleko kumphumela wabo wokusebenza.

I-Varicpand International izibeke njengomkhiqizi ohamba phambili kanye nomphakeli womhlaba wonke wama-coupling ombhobho womlilo we-GOST ne-Rotta, enikeza uhla olubanzi lomkhiqizo oluhlanganisa izinhlobo ze-aluminium, ubhedu, ne-stainless steel ukuze kuhlangatshezwane nezidingo ezahlukahlukene zeminyango yomlilo, izindawo zezimboni, nabasabalalisi emhlabeni wonke.
