I-Metal Seated Ball Valve
Ithini ivalve yebhola ehlezi yensimbi?
I-valve yebhola ingenye yamavalvu athandwa kakhulu ezimbonini ezihlukahlukeneizicinjengokumelana noketshezi oluncane, ishaneli yokugeleza ebushelelezi, ukuvulwa nokuvala ngokushesha, nokulawula okuzenzakalelayo okulula, i-valve yebhola iye yasetshenziswa kabanzi.Kodwa isihlalo noma ama-valve amabhola avamile ngokuvamile enziwa nge-PTFE nezinye izinto ezingezona ezensimbi.Inqunyelwe uphawu lwesihlalo izinto zokwakha, ama-valve ajwayelekile awakwazi ukusetshenziswa ngaphansi kwesimo sesevisi sokushisa okuphezulu noma ukumelana nokugqoka.
Ngakho-ke, uchungechunge lwesitayela esisha practical ama-valve ebhola ahlezi ensimbibabeithuthukisiwe, futhizisetshenziswe kabanzi ku-petroleum, embonini yamakhemikhali, amandla kagesi, i-metallurgy, imboni yokukhanya njll
I-valve yebhola yensimbi iye kweyensimbi ayinayo nje kuphela izinzuzo ezihlukahlukene zamavalvu amabhola avamile asezimbonini, kodwa futhi izici ezithile nezivelele ekuqineni kokushisa, ikakhulukazi lapho uphawu oluthambile lungasetshenziswa, njengalapho ukulethwa kwamapayipi okuphakathi anothuli olukhuhlana phezulu, i-slurry. , kanye nengxube yezindaba zangaphandle eziqinile.
Izici eziyinhloko ze-valve yebhola ehlezi yensimbi?
1.Ibhola Elithuthukisiwe kanye Nobuchwepheshe Bokuqina Kwezihlalo
Ukubekwa uphawu kusetshenziswa insimbi ukuze kudliwe phakathi kwebhola nesihlalo sensimbi samavalvu ebhola. Ngokuvumelana nezimo ezihlukene zesevisi nezimfuneko zabasebenzisi, kungase kusetshenziswe ubuchwepheshe obuhlukahlukene bokuqina bebhola nokuqinisa izihlalo, okuhlanganisa i-HVOF coating, i-nickel-base alloy spray welding, i-high nickel alloy spray welding, i-cobalt case hard alloy spray welding, njll. Ngokuvamile ibhola nobulukhuni besihlalo bungafinyelela ku-HRC55-60 ngenani eliphakeme le-HRC70. futhi ngokuvamile, ukumelana nokushisa kwempahla yobuso obuvaliwe kungaba ngu-540°C. , ngenani eliphakeme elingu-980°C.Izinto ezisetshenziswayo zobuso bokuzilibazisa nazo zinokusebenza okuhle ukumelana nokuguga kanye nokumelana nomthelela.
2.Flexible Valve Ukuvula kanye Ukuvala
Ngaphansi kwesimo sesevisi yokushisa okuphezulu, ibhola nesihlalo kuzokhula kakhulu ngenxa yokwanda okushisayo, futhi i-torque izokhula futhi i-valve ayikwazi ukuvulwa, I-valve yebhola ithatha i-disc spring noma isakhiwo sokuvala i-spring egcwele ukuze ukwandiswa okushisayo kwezingxenye. ngaphansi kokushisa okuphezulu kungamuncwa yi-disc spring noma entwasahlobo.Futhi kuqinisekiswa ukuthi i-valve izovulwa ngokuguquguqukayo futhi ivalwe ngaphansi kokushisa okuphezulu ngaphandle kokwandisa kakhulu.
3. Idizayini Yesakhiwo Sokuvikela Umlilo
Esakhiweni sensimbi kuye kwesensimbi sevalvu, i-gasket iyinsimbi engagqwali+i-graphite eguquguqukayo futhi ukupakishwa kuyi-graphite eguquguqukayo.Ngakho-ke, ukuvalwa okuthembekile kwe-valve kungaqinisekiswa ngisho noma kunomlilo.
4. I-Double Block and Bleed(I-Metal Seated Trunnion Ball Valve)
I-valve yebhola ye-trunnion ehlezi yensimbi ngokuvamile ithatha isakhiwo sokuvala ngaphambi kwebhola.Lapho i-valve ivaliwe futhi i-valve ephakathi ithululwa i-valve yokukhipha, izihlalo ezikhuphuka nomfula zizovimba ngokuzimela uketshezi endaweni yokungena nokuphuma ukuze kubonakale umsebenzi webhulokhi ephindwe kabili.
Ivalvu yebhola entantayo ehlezi eyinsimbi ngokuvamile ithatha isakhiwo sokuvala ngemva kwebhola.Indlela yokugeleza izomakwa emzimbeni ukuze i-valve yebhola ivalwe unidirectional unidirectional sealing.
5. Ukusebenza Okuthembekile Kokuvala
Kusetshenziswa ubuchwepheshe obuyingqayizivele bokugaya ibhola, ngokuzungezisa ibhola kanye ne-grind er ezindaweni ezihlukene. indawo yebhola izofinyelela ukujikeleza nokucoleka okuphezulu. Ukuvalwa kokucindezela okuphansi kwesihlalo se-valve kwenziwa ngo-spring pre-tighted. I-piston effect yesihlalo se-valve iklanywe ngendlela enengqondo, eqaphela ukuvaleka kwengcindezi ephezulu ngoketshezi ngokwalo, Ukuqina kwamavalvu ebhola ehlezi kuhlangabezana nezidingo zeleveli IV ye-ANSI B16.104.

I-valve yebhola entantayo ehlezi ngensimbi
Imininingwane yobuchwepheshe yevalve yebhola ehlezi yensimbi?
Ama-valve ebhola ahlezi ensimbi, umklamo ohlukile webhola elintantayo nebhola le-trunnion.
Amavalvu ebhola antantayo ahlezi ensimbi
I-valve yebhola ye-metal ehlezi
Umbukiso Womkhiqizo:
Ukusetshenziswa kwensimbi ehlezi ama-valve ebhola
Isetshenziselwa ini i-Metal Seated Ball Valve?
Ii-valve yebhola ehlezi yensimbiisetshenziswa kabanzi ukusika noma ukuxhuma abezindaba kumapayipi ahlukahlukene, i-petroleum, imboni yamakhemikhali, amandla kagesi, i-metallurgy, imboni yokukhanya.Ilungele izimo zesevisi ezinzima eziqukethe ama-granules aqinile, i-slurry, impushana yamalahle, i-cinder njll.
