E le ho finyella litlhoko tsa lits'ebetso tsa indasteri tse kang mocheso o phahameng le o tlaase, khoholeho e matla, le bophelo bo bolelele, li-valve tsa serurubele tse tiisitsoeng ka tšepe li entsoe haholo.Ka ts'ebeliso ea ho hanyetsa mocheso o phahameng, ho hanyetsa mocheso o tlase, ho hanyetsa kutu ho matla, ho hanyetsa khoholeho e matla, le lisebelisoa tse matla tsa alloy ka li-valve tsa serurubele, li-valve tsa serurubele tse tiisitsoeng ka tšepe li 'nile tsa sebelisoa haholo libakeng tsa indasteri tse kang mocheso o phahameng le o tlaase, o matla. khoholeho ea mobu, le bophelo bo bolelele.Li-valve tsa butterfly tse nang le bophara bo boholo (9 ~ 750 mm), khatello e phahameng (42.0 MPa), le mocheso o pharaletseng (-196 - 606 ° C) li hlahile.
Ha valve ea serurubele e butsoe ka botlalo, e na le khanyetso e nyane ea phallo.Ha ho buloa ho pakeng tsa hoo e ka bang 15 ° ~ 70 °, ho ka boela ha etsa taolo ea phallo e hlokolosi, kahoo tšimong ea taolo ea bophara bo boholo, ho sebelisoa ha li-valve tsa serurubele ho tloaelehile haholo.
Kaha ho sisinyeha ha poleiti ea serurubele ho hlakola, li-valve tse ngata tsa serurubele li ka sebelisoa bakeng sa mecha ea litaba e nang le likaroloana tse tiileng tse emisitsoeng.Ho itšetlehile ka matla a tiiso, e ka boela ea sebelisoa bakeng sa mecha ea litaba ea powdery le granular.
Li-valve tsa butterfly li loketse ho laola phallo.Kaha tahlehelo ea khatello ea valve ea serurubele phala e batla e le khōlō, hoo e ka bang makhetlo a mararo ho feta a valve ea heke, ha u khetha serurubele, tšusumetso ea tahlehelo ea khatello tsamaisong ea liphaephe e lokela ho nkoa ka botlalo, 'me matla a Letlapa la serurubele ho mamella khatello ea sephaephe sa phaephe ha le koetsoe le lona le lokela ho nkoa..Ho phaella moo, moeli oa mocheso oa ts'ebetso oa lisebelisoa tsa setulo sa elastic ka mocheso o phahameng o tlameha ho nkoa hape.
Bolelele ba sebopeho le bophahamo ka kakaretso ba valve ea serurubele li nyane, lebelo la ho bula le ho koala le potlakile, 'me le na 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 sebelisoa bakeng sa taolo ea phallo, ntho ea bohlokoa ka ho fetisisa ke ho khetha ka nepo tlhaloso le mofuta oa serurubele e le hore e ka sebetsa hantle le ka katleho.
Ka kakaretso, li-valve tsa serurubele li buelloa bakeng sa ho thothomela, taolo ea taolo le mecha ea litaba ea seretse moo bolelele bo khutšoanyane ba sebopeho, lebelo la ho bula le ho koala ka potlako, le ho khaola khatello e tlaase (phapang e nyenyane ea khatello) e hlokahalang.Li-valve tsa butterfly li ka khethoa bakeng sa phetoho ea maemo a mabeli, liteishene tse fokotsehileng tsa bophara, lerata le tlaase, cavitation le vaporization, palo e nyenyane ea ho lutla sepakapakeng, le mecha ea litaba e senyang.Ho lokisoa ha throttle tlas'a maemo a khethehileng a ho sebetsa, kapa maemo a sebetsang a hlokang ho tiisoa ka thata, ho apara ka matla, mocheso o tlaase (cryogenic) joalo-joalo.
