Butterfly valveibhekisela ohlotsheni lwevalvu ingxenye yalo yokuvala (idiski noma ipuleti uvemvane) iyidiski, ezungeza i-valve shaft ukuze ifinyelele ukuvuleka nokuvala.Isetshenziselwa ikakhulukazi ukusika nokudonsa epayipini.
I-valve uvemvane evula futhi evala ingxenye iyipuleti uvemvane okumise okwediski, elizungeza i-eksisi yalo emzimbeni wevalvu ukufeza injongo yokuvula nokuvala noma ukulungisa.I-valve uvemvane ivamise ukuba ngaphansi kuka-90″ ukusuka ekuvulekeni kuya ekuvaleni ngokugcwele,
I-valve uvemvane nesiqu sovemvane azinawo amandla okuzivalela.Ukuze kumiswe ipuleti lovemvane, isinciphisi segiya lezikelemu kufanele sifakwe esiqwini sevalvu.Ukusetshenziswa kwe-worm gear reducer akukwazi nje ukwenza ipuleti le-butterfly lizikhiyele futhi limise ipuleti levemvane kunoma yisiphi isikhundla, kodwa futhi lithuthukise ukusebenza kwe-valve.
I-valve ye-butterfly yezimboni ibonakala ngokumelana nokushisa okuphezulu, uhla lwengcindezi ephezulu esebenzayo, ububanzi obukhulu begama, futhi umzimba we-valve wenziwe nge-carbon steel.
Iringi yokuvala ye-valve plate isebenzisa indandatho yensimbi esikhundleni sendandatho yerabha.I-valve ye-butterfly enkulu yokushisa okuphezulu yenziwe nge-steel plate welding, futhi isetshenziselwa ikakhulukazi amapayipi e-flue namapayipi egesi wemidiya ephezulu yokushisa.
Ukufakwa nokugcinwa kwe-valve ye-butterfly kufanele kunake izinto ezilandelayo: Ngesikhathi sokufakwa, i-valve disc kumele imiswe endaweni evaliwe.Isikhundla sokuvula kufanele sinqunywe ngokuvumelana ne-angle yokujikeleza yepuleti levemvane.
Kuma-butterfly valve ane-bypass valve, i-valve yokudlula kufanele ivulwe ngaphambi kokuvula
Ukufakwa kufanele kwenziwe ngokuvumelana nemiyalelo yokufaka yomkhiqizi, futhi i-valve ye-butterfly esindayo kufanele ifakwe ngesisekelo esiqinile.
Izinzuzo zama-butterfly valves zimi kanje: ukuvulwa nokuvala okulula futhi okusheshayo, ukonga umsebenzi, ukumelana noketshezi oluphansi, futhi kungasetshenziswa njalo.
Isakhiwo esilula, usayizi omncane kanye nesisindo esincane.
Udaka lungathuthwa, ngokunqwabelana okuncane koketshezi emlonyeni wepayipi.
Ngaphansi kwengcindezi ephansi, ukuvala uphawu okuhle kungafinyelelwa.
Ukusebenza okuhle kokulungisa.
Ukungalungi kwama-valve e-butterfly kanje: ububanzi bengcindezi yokusebenza kanye nokushisa okusebenzayo kuncane.
Ukuqina kubi.
Ama-valve e-Butterflyingahlukaniswa ngohlobo lwepuleti ye-offset, uhlobo lwepuleti eqondile, uhlobo lwepuleti ethambekele kanye nohlobo lwe-lever ngokusho kwesakhiwo.Ngokwefomu lokufaka uphawu, lingahlukaniswa ngezinhlobo ezimbili: uhlobo oluvalwe ngokuqhathaniswa nohlobo oluvalwe kanzima.Uhlobo lophawu oluthambile ngokuvamile lusebenzisa indandatho yerabha, futhi uhlobo lophawu oluqinile luvamise ukusebenzisa indandatho yensimbi.
Ngokusho kohlobo lokuxhuma, ingahlukaniswa ibe uxhumano lwe-flange nokuxhumeka kwe-wafer;ngokuya ngemodi yokudlulisa, ingahlukaniswa ngemanuwali, ukuhanjiswa kwegiya, i-pneumatic, i-hydraulic kanye nogesi.
