Ukufakwa kwe-Check Valve
Ivalve yokuhlola kufanele ifakwe lapho kuphuma khona iphampu nangaphambi kwevalvu yokulawula ukuphuma ukuze ilungiswe.Ngokuvamile, i-outlet yokuqala yepompo ukuxhumana okuthambile (i-shock absorber), kulandelwa i-valve yokuhlola, bese kuba i-valve yokuvimba (njenge-butterfly valve, i-valve yesango, i-valve yokumisa, njll.).
1. Faka ivalve yokuhlola kuqala bese emva kwalokho ufake ivalve yesango noma uvemvane
Izinzuzo: ingavikela i-valve yokuhlola, ikakhulukazi kumaphampu ahambisanayo.Lapho iphampu eyodwa ingaqali futhi enye ipompo iqala, amandla okuthinta athwalwa yi-valve yesango noma i-valve uvemvane.
Ukungalungi: ngubani ozovikela i-valve yesango noma i-valve yokuhlola?Kube necala lokuthi ipuleti le-valve le-valve uvemvane liphukile.
2. Faka i-valve yesango noma i-butterfly valve ngaphambi kokuhlola i-valve
Izinzuzo: ingavikela i-valve ye-butterfly noma i-valve yesango, futhi amandla omthelela athwalwa yi-valve yokuhlola
Ukungalungi: ngubani ozovikela i-valve yokuhlola?I-valve yokuhlola ivuliwe futhi ivalwe umehluko wengcindezi.Uma ukucindezela kwekhanda kuphezulu, izovalwa futhi ukucindezela kwepompo kuzovulwa.Uma ukugeleza okusetshenzisiwe kungazinzile, i-valve yokuhlola izovulwa futhi ivalwe ngokuphindaphindiwe, okuzothinta impilo yesevisi ye-valve yokuhlola.
