Kutsengisa lokuhle kwensimbi ye-Ductile halar lenelizinga leliphakeme le-flang lephindvwe kabili lesemkhatsini we-valve yevivane

Ivalvu yeluvivane lecondzene ne-flanges lephindvwe kabili: emavalvu e-flanged concentric butterfly atsatsa sikhundla lesibalulekile ngenca yekusebenta kwawo ngetindlela letinyenti kanye nekusebenta kahle. Lesihloko sihlose kukhanyisela kubaluleka kanye netimphawu talevalve lemangalisako, ikakhulukati emkhakheni wekuhlantwa kwemanti. Ngetulu kwaloko, sitawucoca ngekutsi kutsengisa lokucondzile kwefekthri kwemavalvu lamakhulu e-flanged concentric butterfly aniketa njani tinzuzo letingenakulinganiswa etindlekweni nasekhwalithi. Eyatiwa ngendlela lelula kodvwa lephumelelako, le valve ine disc lefakwe emkhatsini wemaphetselo lamabili e flange. Lesivalo lesicinile emkhatsini we disc nemtimba sicinisekisa kuvuza lokuncane, kwenta kutsi kube kuhle kakhulu ekusebentiseni lokudzinga kuvalwa ngalokuphelele. Ngetulu kwaloko, umklamo wayo lomncane kanye nesisindvo sayo lesilula kwenta kutsi kube melula kufakwa nekunakekelwa.

Uma kukhulunywa ngekuhlantwa kwemanti, emavalvu e-flanged concentric butterfly afakazela kutsi ayintfo lebalulekile kulemboni. Njengoba sidzingo sekulawula emanti ngendlela lefanele siyachubeka nekukhula, le valve seyibe sisombululo lesetsembekile. Isetjentiswa kakhulu ekuphakeleni emanti, kuhlanta imfucuza, titjalo tekususa luswayi kanye naletinye tindzawo. Likhono layo lekulawula kahle kuhamba kwemanti ngesikhatsi icinisekisa kwehla kwemfutfo lophansi kwenta kutsi kube yincenye lebalulekile etindzaweni tekuhlanta emanti.
