I-valve yokuphepha iyisisetshenziswa sokuphepha esizenzakalelayo esingakhulula isitimu ngokushesha lapho umfutho uphezulu kakhulu ukuvimbela izingozi zokuqhuma.Iwumugqa wokugcina wokuzivikela ezingozini zokuphehla isitimu futhi iyingxenye ebalulekile yesisetshenziswa sokuqinisekisa ukuphepha kwempilo kanye nobuqotho bemishini.Ngokuvamile, ijeneretha yesitimu idinga ukufakwa okungenani ngamavalvu okuphepha amabili.Ngokuvamile, ukukhishwa okulinganiselwe kwe-valve yokuphepha kufanele kube ngaphansi komthamo omkhulu wokucubungula we-generator ye-steam ukuze kuqinisekiswe ukusebenza okuvamile ekulayisheni okuphezulu.
Ukugcinwa nokugcinwa kwama-valve okuphepha nakho kubaluleke kakhulu.Ngesikhathi sokusetshenziswa, ukunemba nokuzwela kwe-valve yokuphepha kudingeka kuhlolwe njalo, futhi ukugcinwa kufanele kwenziwe ngokuhambisana ngokuqinile nemiyalelo yokusetshenziswa nokugcinwa kwebhukwana.Uma izimpawu zokwehluleka noma ukungasebenzi zitholakala ku-valve yokuphepha, kufanele ishintshwe noma ilungiswe ngesikhathi ukuze kuqinisekiswe ukusebenza okuphephile kwejeneretha ye-steam.
Ngakho-ke, i-valve yokuphepha kujeneretha yesitimu iwucezu lwesisetshenziswa esibalulekile.Akuyona nje indlela yokugcina yokuvikela ukuqinisekisa ukuphepha kwabasebenzi, kodwa futhi isinyathelo esibalulekile sokuvikela ubuqotho nokuzinza kokusebenza kwempahla.Ukuze siqinisekise ukusebenza okuphephile kwejeneretha ye-steam, kufanele sinake izici eziningi ezifana nokukhetha, ukufakwa, ukugcinwa nokugcinwa kwe-valve yokuphepha.
