1.Moo valve ea serurubele e sebetsang teng
Li-valve tsa butterflyli loketse taolo ea phallo.Kaha khatello ea belofo ea serurubele e pompong e batla e le khōlō, e imena ka makhetlo a mararo ho feta ea belofo ea heke.Ka hona, ha u khetha valve ea serurubele, tšusumetso ea tahlehelo ea khatello ea tsamaiso ea liphaephe e lokela ho nkoa ka botlalo, 'me matla a serurubele a mamelle khatello ea mochine oa liphaephe le oona o lokela ho nkoa ha o koetsoe.thobalano.Ntle le moo, hoa hlokahala ho nahana ka moeli oa mocheso o sebetsang oo lisebelisoa tsa setulo sa valve ea elastic li ka mamellang mocheso o phahameng.
Bolelele ba sebopeho le bophahamo ba kakaretso ea 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 laola phallo, ntho ea bohlokoa ka ho fetisisa ke ho khetha ka nepo boholo le mofuta oa valve ea serurubele ho etsa hore e sebetse hantle le ka katleho.
Ka kakaretso, ha ho lla, ho laola taolo le seretse, bolelele ba sebopeho bo hlokeha hore bo be bokhutšoanyane 'me lebelo la ho bula le ho koala le potlakile (1/4r).Ho fokotsa khatello e tlase (phapang e nyane ea khatello), valve ea serurubele e khothaletsoa.
Tabeng ea ho fetoha ha maemo a mabeli, tsela e fokolang, lerata le tlaase, cavitation le vaporization, palo e nyenyane ea ho lutla sepakapakeng, le mecha ea litaba e senyang, li-valve tsa serurubele li ka sebelisoa.
Ha u sebelisa li-valve tsa serurubele tlas'a maemo a khethehileng a kang taolo ea throttling, litlhoko tse tiileng tsa ho tiisa, ho roala ka matla, mocheso o tlaase (cryogenic) le maemo a mang a ts'ebetso, ho hlokahala moralo o khethehileng bakeng sa eccentric kapa habeli eccentricity e nang le tiiso ea tšepe e entsoeng ka ho khetheha e nang le sesebelisoa sa ho fetola. belofo.
Setsi sa serurubele se bohareng se loketse metsi a hloekileng, likhoerekhoere, metsi a leoatle, metsi a letsoai, mouoane, khase ea tlhaho, lijo, meriana, oli le lihlahisoa tse fapaneng tse hlokang ho tiisoa ka ho feletseng, ho lutla ha tlhahlobo ea khase ea zero, litlhoko tse phahameng tsa bophelo, le mocheso oa ho sebetsa. -10 ~ 150 ℃.Acid-base le liphaephe tse ling.
Belofo ea serurubele e tiisitsoeng ka bonolo e loketse ho bula le ho koala ka litsela tse peli le ho lokisa lipeipi tsa moea le tsa ho tlosa lerole.E sebelisoa haholo liphaepheng tsa khase le litselaneng tsa metsi ho metallurgy, indasteri e bobebe, matla a motlakase le lits'ebetso tsa petrochemical.
Thepa ea tšepe-to-metal e tiisang serurubele se nang le serurubele se habeli se loketse ho futhumatsa litoropong, mouoane, metsi le khase, oli, acid le liphaephe tsa alkali, e le sesebelisoa se laolang le ho thibela.
Ntle le ho sebelisoa e le sekhahla se seholo sa khatello ea khatello ea motlakase (PSA) ea ho arola lisebelisoa tsa khase, sesebelisoa sa tšepe-to-metal seal seal triple eccentric butterfly valve se ka sebelisoa haholo ho petroleum, petrochemical, chemical, metallurgical, motlakase. matla le masimo a mang.Ke valve ea heke, valve ea ho emisa, joalo-joalo Sehlahisoa se setle sa mefuta e meng.
2.Molao-motheo oa khetho ea valve ea serurubele
1. Kaha valve ea serurubele e na le tahlehelo e batlang e le khōlō ea khatello ha e bapisoa le valve ea heke, e loketse lisebelisoa tsa liphaephe tse nang le litlhoko tse fokolang tsa khatello ea khatello ea kelello.
2. Kaha valve ea serurubele e ka sebelisoa ho fetola phallo, e loketse ho sebelisoa liphaepheng tse hlokang ho fetoloa ha phallo.
3. Ka lebaka la moeli oa sebopeho sa valve ea serurubele le thepa ea ho tiisa, ha e tšoanelehe bakeng sa mocheso o phahameng le tsamaiso e phahameng ea liphaephe.Ka kakaretso, mocheso o sebetsang o ka tlase ho 300 ℃, 'me khatello ea lebitso e ka tlase ho PN40.
4. Kaha bolelele ba sebopeho sa valve ea serurubele se batla se le khutšoanyane 'me se ka etsoa ka bophara bo boholo, valve ea serurubele e lokela ho sebelisoa maemong ao bolelele ba mohaho bo hlokahalang hore bo be bokhutšoane kapa valve e kholo ea bophara (e kang DN1000). kapa ho feta).
5. Kaha valve ea serurubele e ka buloa kapa ea koaloa ka ho potoloha 90 ° feela, ho molemo ho khetha valve ea serurubele liketsahalong tse hlokang ho bula le ho koala ka potlako.
