Li-valve tsa butterfly li loketse ho laola phallo. Kaha khatello ea khatello ea valve ea serurubele phapeng e batla e le khōlō, e leng hoo e ka bang ka makhetlo a mararo ho feta ea valve ea heke, ha u khetha valafo ea serurubele, tšusumetso ea tahlehelo ea khatello tsamaisong ea lipeipi e lokela ho nahanoa ka botlalo, le ho tiea ha phaephe e nang le poleiti ea serurubele. khatello e mahareng ha ho koaloa le eona e lokela ho nahanoa. Ho phaella moo, moeli oa mocheso o sebetsang oa lisebelisoa tsa setulo sa elastic ka mocheso o phahameng o tlameha ho nkoa.

Belofo ea serurubele e na le bolelele bo bonyenyane ba sebopeho le bophahamo ka kakaretso, lebelo la ho bula le ho koala kapele, le litšobotsi tse ntle tsa taolo ea mokelikeli. Molao-motheo oa sebopeho sa valve ea serurubele o loketse ka ho fetisisa bakeng sa ho etsa li-valve tsa bophara bo boholo. Ha valve ea serurubele e hlokeha ho laola phallo, ntho ea bohlokoa ka ho fetisisa ke ho khetha ka nepo boholo le mofuta oa valve ea serurubele e le hore e ka sebetsa hantle le ka katleho.

Ka kakaretso, taolong le taolong le bohareng ba seretse, bolelele bo khuts'oane ba sebopeho le lebelo la ho bula le ho koala kapele (1 / 4 turn) lia hlokahala. Khatello e fokolang ea khatello e tlaase (khatello e nyenyane ea phapang), valve ea serurubele e khothalletsoa.

Li-valve tsa butterfly li ka khethoa haeba ho na le taolo ea maemo a mabeli, mocha oa fatše o nang le molala, lerata le tlaase, cavitation le gasification, ho lutla ho honyenyane ho ea sepakapakeng le bohareng ba abrasive.

Ha valve ea serurubele e sebelisoa tlas'a maemo a khethehileng a ho sebetsa, joalo ka taolo ea throttling, litlhoko tse tiileng tsa ho tiisa, kapa ho apara ka matla, mocheso o tlase (cryogenic) le maemo a mang a ho sebetsa, hoa hlokahala ho sebelisa li-valve tse khethehileng tse tharo kapa tse peli tse nang le serurubele se khethehileng. e etselitsoeng tiiso ea tšepe le sesebelisoa sa ho laola.

Sesepa sa serurubele se bohareng se sebetsa ho metsi a hloekileng, likhoerekhoere, metsi a leoatle, brine, mouoane, khase ea tlhaho, lijo, meriana, lihlahisoa tsa oli, acid e fapaneng le alkali le liphaephe tse ling tse hlokang ho tiisoa ka ho feletseng, ho lutla ha tlhahlobo ea khase ea zero, bophelo ba tšebeletso e phahameng le mocheso o sebetsang. ea – 10 ℃ ~ 150 ℃.

Soft seal eccentric butterfly valve e loketse ho buloa ka litsela tse peli, ho koala le ho lokisa moea le phaephe ea ho tlosa lerōle. E sebelisoa haholo liphaepheng tsa khase le mocha oa metsi oa metallurgy, indasteri e khanyang, matla a motlakase le tsamaiso ea petrochemical.

Metal to metal e tiisitsoeng habeli eccentric butterfly valve e loketse ho futhumala ha litoropo, phepelo ea khase, phepelo ea metsi le khase e 'ngoe, oli, acid-base le liphaephe tse ling e le sesebelisoa sa taolo le se otlang.
