Insimbi Ehlanganisiwe Umzimba Ohlanganisiwe Ogcwele Insimbi Engagqwali Ibhola Eliyinsimbi Engagqwali Umshini Wokushisela Obekwe Emuva Umkhiqizi we-valve yebhola le-ATEX
Iyini i-Ball valve ATEX?
I-valve yebhola i-ATEX 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.
Izici eziyinhloko ze-Ball valve 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.
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.

Ukusetshenziswa kwe-Ball valve ATEX
I-Ball valve ATEX isetshenziselwani?
II-valve yebhola i-ATEXisetshenziswa 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.
