A serurubele belofoke mofuta oa valve o lokisang phallo ea sehare ka ho o bula kapa ho o koala ka ho retelehela pele le morao hoo e ka bang likhato tse 90. Ntle le moralo oa eona o otlolohileng, boholo bo nyane, boima bo bobebe, tšebeliso e tlase ea thepa, ho kenya habonolo, torque e tlase ea ho khanna, le ts'ebetso e potlakileng.serurubele belofoe boetse e sebetsa hantle mabapi le taolo ea phallo ha e ntse e e-na le litšobotsi tse ntle tsa ho koala le ho tiisa. e 'ngoe ea mefuta e potlakileng ea li-valve. Tšebeliso eali-valve tsa serurubelee tloaelehile.

Tšebeliso ea eona e ntse e tsoela pele ho fapana le ho eketseha, 'me e ntse e fetohela mocheso o phahameng, khatello e phahameng, bophara bo boholo, tiiso e phahameng, bophelo bo bolelele, litšoaneleho tse ikhethang tsa phetoho, le mesebetsi e mengata ea valve. Hona joale e na le boemo bo phahameng ba ho tšepahala le litšobotsi tse ling tsa tshebetso.

Ts'ebetso ea li-valve tsa serurubele e ntlafetse ka lebaka la ts'ebeliso ea rabara ea maiketsetso e hanyetsanang le lik'hemik'hale. Kaha rabara ea maiketsetso e na le litšoaneleho tsa ho hanyetsa kutu, ho hanyetsa khoholeho ea mobu, boholo bo tsitsitseng, matla a matle, bonolo ba ho theha, le theko e tlaase, rabara ea maiketsetso e nang le thepa e sa tšoaneng e ka khethoa ho latela litlhoko tse fapaneng tsa kopo ho khotsofatsa maemo a sebetsang a li-valve tsa serurubele.

Kaha polytetrafluoroethylene (PTFE) e na le khanyetso e matla ea ho senya, ts'ebetso e tsitsitseng, ho hanyetsa botsofali, coefficient e tlase ea likhohlano, boiketlo ba ho bōptjoa, le botsitso ba boholo, ts'ebetso ea eona ka kakaretso e ka ntlafatsoa ka ho tlatsa le ho eketsa lisebelisoa tse loketseng ho fumana matla le matla a molemo. khohlano. Rabara ea maiketsetso e na le mathata a itseng, empa lisebelisoa tsa ho tiisa valve ea serurubele tse nang le coefficient e tlase lia li potoloha. E le ho ntlafatsa ts'ebetso ea li-valve tsa serurubele, lisebelisoa tse phahameng tsa polymer ea molek'hule, tse kang polytetrafluoroethylene, le lisebelisoa tsa bona tse fetotsoeng tsa ho tlatsa li 'nile tsa sebelisoa haholo. Hona joale e se e ntlafalitsoe, 'me valve ea serurubele e hlahisitsoe ka mocheso o moholoanyane le khatello ea khatello, ts'ebetso e ka tšeptjoang ea ho tiisa, le bophelo bo bolelele bo sebetsang.

Li-valve tsa serurubele tse tiisitsoeng ka tšepe li tsoetse pele haholo molemong oa ho phethahatsa litlhoko tsa lits'ebetso tsa indasteri joalo ka mocheso o phahameng le o tlase, khoholeho e matla le bophelo bo atolositsoeng. Li-valve tsa serurubele tse tiisitsoeng ka tšepe li 'nile tsa sebelisoa haholo masimong a indasteri a kang mocheso o phahameng le o tlaase, khoholeho e matla, le bophelo bo bolelele ka lebaka la ho sebelisoa ha mocheso o phahameng oa mocheso, ho hanyetsa mocheso o tlase, ho hanyetsa kutu ho matla, ho hanyetsa khoholeho e matla, le matla a phahameng. lisebelisoa tsa motsoako. E le ho ntšetsa pele theknoloji ea valve ea serurubele, bophara bo boholo (9-750mm), khatello e phahameng (42.0MPa), le mefuta e mengata ea mocheso (-196-606 ° C) li-valve tsa serurubele li ile tsa qala ho hlaha.

Belofo ea serurubele e na le khanyetso e nyane ea ho phalla ha e butsoe ka botlalo. Li-valve tsa serurubele li sebelisoa khafetsa lefapheng la taolo ea bophara bo boholo hobane li khona ho laola phallo e bobebe libakeng tse lipakeng tsa 15 ° le 70 °.

Bongata ba li-valve tsa serurubele li ka sebelisoa mecheng ea litaba e nang le likaroloana tse tiileng tse emisitsoeng kaha poleiti ea serurubele e tsamaea e ntse e phumula. E ka boela ea sebelisoa bakeng sa mecha ea litaba ea granular le powdery, ho itšetlehile ka matla a tiiso.

Li-valve tsa butterfly li bohlokoa bakeng sa ho laola phallo. Ha u khetha valve ea serurubele, ho bohlokoa ho nahana ka botlalo phello ea tahlehelo ea khatello tsamaisong ea liphaephe hammoho le matla a serurubele ho mamella khatello ea serurubele ha se koetsoe ka lebaka la tahlehelo ea khatello ea serurubele. belofo e phalang e batla e le khōlō, hoo e ka bang makhetlo a mararo ho feta ea valve ea heke. Thempereichara ea ts'ebetso ea lisebelisoa tsa setulo sa elastic ka mocheso o phahameng le eona e tlameha ho nkoa.

Belofo ea serurubele e na le sebopeho se sekhutšoane le bolelele bo tlase ka kakaretso. E bula le ho koala kapele mme e na le thepa e ntle ea ho laola mokelikeli. Ho etsa li-valve tsa bophara bo boholo ho loketse ka ho fetisisa moetsong oa sebopeho sa valve ea serurubele. Mohato oa bohlokoa ka ho fetisisa oa ho khetha valve ea serurubele e tla sebetsa hantle le ka katleho ha e sebelisoa ho laola phallo ke ho khetha mofuta o nepahetseng le litlhaloso.

Li-valve tsa serurubele hangata li eletsoa hore li sebelisoe ho thethefatsa, ho laola taolo, le mecha ea litaba ea seretse moo bolelele bo khuts'oane ba sebopeho, lebelo le potlakileng la ho bula le ho koala, le ho fokotsa khatello e tlase (phapang e nyane ea khatello) e hlokahalang. Li-valve tsa serurubele li ka sebelisoa ka mecha ea litaba e senyang, likanale tse fokotsehileng, lerata le tlase, cavitation le vaporization, ho lutla ha sepakapaka, le phetoho ea maemo a mabeli. Tokiso ea throttle ha u sebetsa tlas'a maemo a sa tloaelehang, joalo ka ha ho tiisoa ka thata, ho roala ho feteletseng, mocheso o tlase haholo, joalo-joalo.
