Umkhiqizi/Umhlinzeki waseShayina i-valve yebhola eqinisekisiwe ye-ATEX
Iyini ivalvu yebhola ye-ATEX?
I-valve yebhola ingenye yama-valve athandwa kakhulu emikhakheni eyahlukahlukene. NgalokhuiziciNjengokumelana noketshezi okuncane, isiteshi sokugeleza esibushelelezi, ukuvulwa nokuvalwa okusheshayo, kanye nokulawula okuzenzakalelayo okulula, ivalvu yebhola isetshenziswe kabanzi.
Ngakho-ke, uchungechunge lwezindlela ezintsha zokusebenzisa isitayelaAma-valve ebhola le-ATEX babeithuthukiswe, 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 zevalvu yebhola ye-ATEX?
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.
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.
I-valve yebhola ye-trunnion ehleli ngensimbi
I-valve yebhola entantayo ehleli ngensimbi
Imininingwane yobuchwepheshe yevalvu yebhola ye-ATEX?
Amavalvu ebhola ahleli ngensimbi, umklamo ohlukile webhola elintantayo nebhola le-trunnion.
Umbukiso Womkhiqizo: I-valve yebhola ye-ATEX
Ukusetshenziswa kwe-valve yebhola ye-ATEX
I-valve yebhola ye-ATEX isetshenziselwa ini?
I-valve yebhola ye-ATEX isetshenziswa kabanzi ukusika noma ukuxhuma imidiya emipayipini ehlukahlukene, imboni kaphethiloli, imboni yamakhemikhali, amandla kagesi, imboni yensimbi, imboni yokukhanya. Ifaneleka ezimweni ezinzima zesevisi eziqukethe ama-granules aqinile, i-slurry, i-coal powder, i-cinder njll.
