I-valve ye-butterfly ye-centerline inesakhiwo esilula futhi kulula ukuyikhiqiza, kodwa ngenxa yesakhiwo sayo nokulinganiselwa kwezinto ezibonakalayo, izimo zokufaka isicelo zilinganiselwe.Ukuze kuhlangatshezwane nezidingo zezimo zangempela zohlelo lokusebenza, kuye kwenziwa ukuthuthukiswa okuqhubekayo ngalesi sisekelo, kwase kuvela amavalvu ovemvane ane-eccentric eyodwa, ama-valve evemvane ane-eccentric kabili, kanye namavalvu ovemvane ane-eccentric kathathu.Isici esikhulu salokhu kugqama kwesithathu ukuthi sishintsha ngokuyisisekelo ukwakheka kokuvala.Akuseyona uphawu lwe-positional, kodwa uphawu lwe-torsion, okungukuthi, alunciki ekuguquguqukeni okunwebekayo kwesihlalo se-valve, kodwa kuncike ngokuphelele ekucindezelweni kwendawo yokuxhumana yesihlalo se-valve.Umthelela wokuvala, ngakho-ke, uxazulula inkinga yokuvuza okunguziro kwesihlalo se-valve yensimbi endaweni eyodwa, futhi ngenxa yokuthi ingcindezi yendawo yokuxhumana ilingana nengcindezi ephakathi nendawo, ingcindezi ephezulu kanye nokumelana nokushisa okuphezulu nakho kuxazululeka kalula.

Izinzuzo ze-triple eccentric design

1. Umklamo oyingqayizivele we-conical seal uqinisekisa ukuthi i-disc ayithinti indawo yokuvala kuze kube yilapho i-valve ivaliwe-lokhu kuholela esicini esiphindaphindiwe futhi kwandisa kakhulu impilo yesevisi ye-valve.

2. Ukuma kwepuleti ye-valve ye-valve ye-butterfly eccentric kathathu i-elliptical cone, futhi ubuso bayo buhlanganiswe ne-alloy eqinile, enokumelana okuhle kakhulu kokugqoka.Isihlalo sensimbi engagqwali esintantayo esimise oku-U sinomsebenzi wokuzilungisa ngokuzenzakalelayo isikhungo.Lapho i-valve ivulwa, i-elliptical cone sealing surface valve disc iqala ukuhlukaniswa nesihlalo sevalve esimise okwe-U, bese ijikeleza;uma ivaliwe, i-disc ye-valve ijikeleza, futhi i-valve disc ilungisa ngokuzenzakalelayo isikhungo esihlalweni se-valve elastic ngaphansi kwesenzo se-eccentric shaft.Isihlalo sisebenzisa ingcindezi yokuguqula isihlalo se-valve kuze kube yilapho isihlalo se-valve kanye ne-elliptical conical seal surface ye-valve disc kufanelana eduze.Lapho i-valve ivuliwe futhi ivaliwe, i-butterfly disc ayikhuzi isihlalo se-valve, futhi i-torque yesiqu se-valve idluliselwa ngokuqondile endaweni yokuvala ngepuleti levemvane, futhi i-torque yokuvula incane, ngaleyo ndlela isuse into evamile yokugxuma. lapho uvula i-valve.

3. Ukuvalwa kwensimbi-kuya-kwensimbi kuqinisekisa ukuthi amabhamuza omoya avaliwe ngokuqinile ukuze kuzuzwe ukusebenza kokuvuza okuyiziro

4. Ifanele imithombo yezindaba enokhahlo-isakhiwo sensimbi yonke sinikeza ukugqwala nokumelana nokushisa amanye amadizayini ovemvane ovamvane anezimpawu zokunwebeka angenawo.

5. Idizayini yejiyomethri yezingxenye zokuvala inganikeza ukuhamba okungenantambo kuyo yonke i-valve.Lokhu kwandisa impilo ye-valve futhi kuvumela ukufakwa kwama-actuator e-torque aphansi.

6. Akukho umgodi phakathi kwezingxenye zokuvala, okungeke kubangele ukuvinjelwa, ukunciphisa izindleko zokunakekelwa nokwandisa impilo ye-valve.

7. Ukuklanywa kwesihlalo se-valve kungavimbela i-valve ekushayeni ngokweqile
