Uyini umehluko phakathi kwevalve uvemvane oluyisilutshwana kanye nevalve uvemvane we-flange?

Ama-valve e-butterflyfuthiflange butterfly valveskukhona izinhlobo ezimbili ezivamile uvemvane valve.Zombili izinhlobo zamavalvu ovemvane zinezinhlelo eziningi ezihlukene, kodwa abangani abaningi abakwazi ukuhlukanisa phakathi kwamavalve ovemvane oluyiluphale namavalve ovemvane abaphendukile, futhi abawazi umehluko phakathi kwakho kokubili.

I-wafer ye-butterfly valve kanye ne-flange izindlela ezimbili zokuxhuma.Ngokwentengo, uhlobo lwe-wafer lushibhile, intengo icishe ibe ngu-2/3 we-flange.Uma ufuna ukukhetha ama-valve angenisiwe, sebenzisa uhlobo lwe-wafer ngangokunokwenzeka, olushibhile futhi olulula ngesisindo.

Ama-valve ohlobo lwe-wafer anamabhawodi amade futhi adinga ukunemba okuphezulu kokwakhiwa.Uma ama-flange ezinhlangothini zombili engaqondani, amabhawodi azofakwa ngaphansi kwamandla amakhulu okugunda, futhi i-valve ijwayele ukuvuza.

Amabhawudi ohlobo lwe-butterfly ohlobo lwe-wafer avamise ukuba made.Ngaphansi kwezimo zokushisa eziphakeme, ukunwetshwa kwe-bolt kungase kubangele ukuvuza, ngakho-ke akufanelekile ama-diameters amapayipi amakhulu ngaphansi kwezimo eziphakeme zokushisa.Ukwengeza, ama-valve emvemvane eyi-wafer ngokuvamile awakwazi ukusetshenziswa ekugcineni kwepayipi nangezansi komfula lapho edinga ukuhlakazwa khona, ngoba uma i-flange engezansi yomfula ihlakazwa, ivalve ye-wafer izowa.Kulokhu, isigaba esifushane kufanele senziwe ngokwehlukana.Ukuze uhlakaze, futhi i-valve ye-butterfly yohlobo lwe-flange ayinayo izinkinga ezingenhla, kodwa izindleko zizoba phezulu.

I-valve ye-butterfly eyi-wafer ayinawo ama-flange kuzo zombili iziphetho zomzimba we-valve, izimbobo ezimbalwa kuphela zamabhawudo, futhi i-valve ixhunywe nama-flange emikhawulweni yomibili ngesethi yamabhawudi/amantongomane.Ngokuphambene, ukuqaqa kulula kakhulu, futhi izindleko zevalvu ziphansi, kodwa okubi ukuthi indawo eyodwa yokuvala inenkinga, futhi zombili izindawo zokuvala kufanele zihlakazwe.

I-valve ye-butterfly yohlobo lwe-flange inama-flange kuzo zombili iziphetho zomzimba we-valve, exhunywe ne-flange yepayipi, futhi ukuvala uphawu kunokwethenjelwa kakhulu, kodwa izindleko zokukhiqiza ama-valve ziphakeme kakhulu.
