Ifektri enomlando weminyaka engaphezu kwengu-20 we-ductile iron halar coating ene-double flange concentric butterfly valve CF8/CF8M disc esezingeni eliphezulu eyenziwe eShayina

I-valve ye-Butterfly ehlanganisiwe kabili: amavalvu ebhabhathane acwebezelayo anendawo ebalulekile ngenxa yokuguquguquka kwawo nokusebenza kahle kwawo. Lesi sihloko sihlose ukukhanyisa ukubaluleka nezici zale valve engavamile, ikakhulukazi emkhakheni wokwelashwa kwamanzi. Ngaphezu kwalokho, sizoxoxa ngendlela ukuthengiswa okuqondile kwefektri kwamavalvu ebhabhathane amakhulu acwebezelayo acwebezelayo anikeza ngayo izinzuzo ezingenakuqhathaniswa ngezindleko nangekhwalithi. Eyaziwa ngomklamo wayo olula kodwa ophumelelayo, le valve iqukethe idiski ebekwe phakathi kweziphetho ezimbili zeflange. Ukuvalwa okuqinile phakathi kwediski nomzimba kuqinisekisa ukuvuza okuncane, okwenza kube kuhle kakhulu ekusetshenzisweni okudinga ukuvalwa okuphelele. Ngaphezu kwalokho, ukwakheka kwayo okufushane kanye nesisindo esincane kwenza kube lula ukufaka nokulungisa.

Uma kukhulunywa ngokwelashwa kwamanzi, amavalvu ebhabhathane acwebezelayo abonakala eyimpahla ebalulekile embonini. Njengoba isidingo sokuphathwa kwamanzi okuphumelelayo siqhubeka nokukhula, leli valve seliyisisombululo esithembekile. Lisetshenziswa kabanzi ekuhlinzekweni kwamanzi, ekuhlinzekweni kwamanzi angcolile, ezitshalweni zokukhipha usawoti kanye neminye imikhakha. Amandla alo okulawula ngokunembile ukugeleza kwamanzi ngenkathi liqinisekisa ukwehla kwengcindezi ephansi lenza libe yingxenye ebalulekile ezindaweni zokwelashwa kwamanzi.
