Butterfly valve, eo hape e tsejoang e le flap valve, ke sebopeho se bonolo sa valve ea taolo, empa hape e ka sebelisoa bakeng sa taolo e tlase ea khatello ea liphaephe tse mahareng. Butterfly valve e bua ka mofuta oa valve eo karolo ea eona ea ho koala (disc kapa disc) e leng disc, e potolohang ho potoloha shaft ho bula le ho koala. Haholo-holo e bapala karolo ea ho khaola le ho phunya lipeipi. Karolo e bulang le e koalang ea valve ea serurubele ke poleiti ea serurubele e bōpehileng joaloka disc, e potolohang ho pota-pota axis ea eona 'meleng oa valve, e le ho finyella morero oa ho bula le ho koala kapa ho lokisa. Butterfly valve e sebetsa pompong e fetisang liphaephe tse fapaneng tse senyang le tse sa cheng ka jenereithara, khase, khase ea tlhaho, khase ea peterole, khase ea toropo, moea o batang le o chesang, ho qhibilihisa lik'hemik'hale le ho fehla matla le lits'ebetso tsa boenjiniere ba ts'ireletso ea tikoloho, tse sebelisetsoang laola le ho kgaola phallo ya seaplane.
Tšebeliso ea valve ea serurubele
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 makhetlo a ka bang mararo ho feta ea valve ea heke, tšusumetso ea tahlehelo ea khatello tsamaisong ea lipeipi e lokela ho nahanoa ka botlalo ha ho khethoa valve ea serurubele, 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 thepa ea setulo se tsitsitseng mocheso o phahameng o tlameha ho nkoa.
Bolelele ba sebopeho le bolelele ba kakaretso ba valve ea serurubele bo 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 haholo ho etsa valve e kholo ea bophara. Ha valve ea serurubele e hlokeha ho sebelisoa bakeng sa taolo ea phallo, ntho ea bohlokoa ka ho fetisisa ke ho khetha ka nepo boholo le mofuta oa serurubele, e le hore e ka sebetsa hantle le ka katleho.
Ka kakaretso, ho throttling, taolo ea taolo le bohareng ba seretse, bolelele ba sebopeho se khuts'oane le lebelo la ho bula le ho koala kapele (1 / 4R) lia hlokahala. Ho fokotsa khatello e tlase (phapang e nyane ea khatello), valve ea serurubele e khothaletsoa.
Li-valve tsa serurubele li ka sebelisoa ha ho etsoa phetoho ea maemo a mabeli, mocha oa contraction, lerata le tlase, cavitation le phenomenon ea gasification, palo e nyane ea ho lutla sepakapakeng, le mahareng a abrasive.
Ha valve ea serurubele e sebelisoa tlas'a maemo a khethehileng a ho sebetsa, joalo ka taolo ea throttling, ho tiisa ka thata, ho roala ho matla le mocheso o tlase (ho pholile ho tebileng), valve e khethehileng ea serurubele e nang le moralo o khethehileng oa tšepe ea ho tiisa lebanta le laolang sesebelisoa se tla sebelisoa.
Belofo ea serurubele e bohareng e loketse metsi a hloekileng, likhoerekhoere, metsi a leoatle, metsi a letsoai, mouoane, khase ea tlhaho, lijo, meriana, oli le liphaephe tse fapaneng tsa acid-base le liphaephe tse ling tse hlokang ho tiisoa ka botlalo, ho lutla ha tlhahlobo ea khase ea zero, litlhoko tse phahameng tsa bophelo. , le mocheso o sebetsang oa - 10 ~ 150 ℃.
E sebelisoa haholo ho metallurgy, indasteri ea leseli, matla a motlakase, petrochemical system pipeline ea khase le mocha oa metsi.
Metal ho tšepe terata e tiisitsoeng habeli eccentric serurubele belofo e loketse bakeng sa phepelo ea mocheso litoropong, phepelo ea mouoane, phepelo ea metsi le khase, oli, acid le liphaephe tsa alkali joalo ka lisebelisoa tse laolang le ho thibela.
Metal to metal seal triple eccentric butterfly valve ha e sebelisoe feela e le belofo ea taolo ea sesebelisoa se seholo sa khatello ea khatello ea adsorption (PSA), empa hape e sebelisoa haholo ho petroleum, petrochemical, lik'hemik'hale, metallurgy, matla a motlakase le masimo a mang. Ke sebaka se setle sa valve ea heke le valve ea ho emisa.
Molao-motheo oa khetho ea valve ea serurubele
1. Ha ho bapisoa le valve ea heke, tahlehelo ea khatello ea valve ea serurubele e kholoanyane, kahoo e loketse tsamaiso ea lipeipi e nang le litlhoko tse fokolang tsa tahlehelo ea khatello.
2. Kaha valve ea serurubele e ka fetoloa ka ho phalla, e loketse ho khethoa ka pipeline e hlokang taolo ea phallo.
3. Ka lebaka la moeli oa sebopeho le thepa ea ho tiisa ea valve ea serurubele, ha e loketse mocheso o phahameng le tsamaiso ea lipeipi tsa khatello e phahameng. Mocheso o akaretsang oa ho sebetsa o ka tlase ho 300 ℃ mme khatello ea lebitso e ka tlase ho PN40.
4. Kaha bolelele ba sebopeho sa valve ea serurubele bo batla bo le bokhutšoanyane, 'me bo ka etsoa ka bophara bo boholo, kahoo tabeng ea bolelele ba mohaho o khutšoanyane kapa valve e kholo ea bophara (e kang ho feta DN 1000), valve ea serurubele e lokela ho khethoa.
5. Kaha valve ea serurubele e ka buloa kapa ea koaloa feela ka ho potoloha ha 90 °, ho loketse ho khetha valve ea serurubele tšimong ka litlhoko tsa ho bula le ho koala ka potlako.
