I-Weld Ball Valve Egcwele
Iyini i-Full Weld Ball Valve?
I-valve yebhola ingenye yama-valve athandwa kakhulu emikhakheni eyahlukahlukene. NgalokhuiziciNjengokumelana okuncane koketshezi, isiteshi sokugeleza esibushelelezi, ukuvulwa nokuvalwa okusheshayo, kanye nokulawula okuzenzakalelayo okulula, ivalvu yebhola isetshenziswe kabanzi. Kodwa isihlalo noma amavalvu ebhola ajwayelekile ngokuvamile enziwe nge-PTFE nezinye izinto ezingezona ezensimbi. Inqunyelwe yizinto zokuvala isihlalo, amavalvu ajwayelekile awakwazi ukusetshenziswa ngaphansi kwesimo sesevisi sokushisa okuphezulu noma ukumelana nokuguguleka.
Ngakho-ke, uchungechunge lwezindlela ezintsha zokusebenzisa isitayelal amavalvu ebhola ahleli ngensimbibabeithuthukiswe, futhiKusetshenziswe kabanzi embonini kaphethiloli, embonini yamakhemikhali, kumandla kagesi, ensimbi, embonini yokukhanya njll.
I-valve yebhola yesihlalo sensimbi kuya kwensimbi ayinazo nje izinzuzo ezahlukahlukene zama-valve ebhola ezimboni avamile, kodwa futhi inezici ezikhethekile nezivelele ekuqineni kokushisa, ikakhulukazi lapho uphawu oluthambile lungasetshenziswa, njengokulethwa kwamapayipi kwe-medium enothuli oluphezulu lokungqubuzana, i-slurry, kanye nengxube yezinto zangaphandle eziqinile.
Izici eziyinhloko ze-Full Weld Ball Valve?
1. Ubuchwepheshe Bokuqinisa Ibhola Nesihlalo Esithuthukisiwe
Ukuvalwa kwenziwa ngensimbi ukuze kudliwe phakathi kwebhola nesihlalo sensimbi sama-valve ebhola. Ngokwezimo zesevisi ezahlukene kanye nezidingo zabasebenzisi, ubuchwepheshe obuhlukahlukene obuthuthukisiwe bokuqinisa ibhola nezihlalo bungasetshenziswa, kufaka phakathi i-HVOF coating, i-nickel-base alloy spray welding, i-nickel alloy spray welding ephezulu, i-cobalt case hard alloy spray welding, njll. Ngokuvamile ubulukhuni bebhola nesihlalo bungafinyelela ku-HRC55-60 ngenani eliphezulu le-HRC70. futhi ngokuvamile, ukumelana nokushisa kwezinto zobuso zokuvala kungaba ngu-540°C, ngenani eliphezulu le-980°C. Izinto zobuso zokuvala nazo zinamandla okumelana nokuguguleka kanye nokumelana nokuthinteka.
2. Ukuvulwa Nokuvalwa Kwevalvu Eguquguqukayo
Ngaphansi kwesimo sesevisi sokushisa okuphezulu, ibhola nesihlalo kuzokhula kakhulu ngenxa yokwanda kokushisa, futhi i-torque izokwanda futhi i-valve ayikwazi ukuvulwa, I-valve yebhola isebenzisa isakhiwo sokuvala i-disk spring noma i-spring ukuze ukwanda kokushisa kwezingxenye ezingaphansi kokushisa okuphezulu kungene yi-disk spring noma i-spring. Futhi kuqinisekiswa ukuthi i-valve izovulwa futhi ivalwe kalula ngaphansi kokushisa okuphezulu ngaphandle kokukhula kakhulu.
3. Umklamo Wesakhiwo Ongashiswa Ngumlilo
Esakhiweni se-valve kusukela kwensimbi kuya kwensimbi, i-gasket iyi-graphite engagqwali + eguquguqukayo futhi ukupakisha kuyi-graphite eguquguqukayo. Ngakho-ke, ukuvalwa okuthembekile kwe-valve kungaqinisekiswa ngisho noma kwenzeka umlilo.
4. I-Double Block kanye ne-Ophed (I-Metal Seated Trunnion Ball Valve)
Ivalvu yebhola ye-trunnion ehlezi ngensimbi ivame ukusebenzisa isakhiwo sokuvala ngaphambi kwebhola. Lapho ivalvu ivaliwe futhi umgodi ophakathi ukhishwa, ivalvu yokukhipha, izihlalo ezingenhla nezingezansi zizovimba uketshezi ngokuzimela endaweni yokungena kanye neyokuphuma ukuze kufezwe umsebenzi wamabhulokhi amabili.
I-valve yebhola entantayo ehlezi ngensimbi ivame ukusebenzisa isakhiwo sokuvala ngemuva kwebhola. Isiqondiso sokugeleza sizomakwa emzimbeni wokuvala i-valve yebhola ngendlela eyodwa. Uma kuchazwe ngabasebenzisi bokugcina, ukuvala i-bidirectional kungenziwa.
5. Ukusebenza Kokuvala Okuthembekile
Ubuchwepheshe bokugaya amabhola obuhlukile buyasetshenziswa, ngokujikeleza kwebhola kanye nomshini wokugaya ezindaweni ezahlukene. Ubuso bebhola buzofinyelela ukujiya okuphezulu kanye nobukhulu. Ukuvalwa kwesihlalo se-valve ngengcindezi ephansi kuqashelwa ngokuqina kwentwasahlobo. Ngaphezu kwalokho, umphumela we-piston wesihlalo se-valve waklanywa ngendlela efanele, okwenza ukuvalwa kwengcindezi ephezulu kube uketshezi uqobo, ukuqina kwama-valve ebhola ahleli ensimbi kuhlangabezana nezidingo zezinga IV le-ANSI B16.104.

Umbukiso Womkhiqizo:
Ukusetshenziswa kwe-Full Weld Ball Valve
I-Metal Seated Ball Valve isetshenziselwa ini?
Iivalvu yebhola ehleli ngensimbiisetshenziswa kabanzi ukusika noma ukuxhumanisa imidiya emipayipini ehlukahlukene, i-petroleum, imboni yamakhemikhali, amandla kagesi, i-metallurgy, imboni yokukhanya. Ifaneleka ezimweni ezinzima zesevisi eziqukethe ama-granules aqinile, i-slurry, i-coal powder, i-cinder njll.
