Umlawuli wokunciphisa ingcindezi uyivalvu enciphisa ingcindezi yokungena iye kungcindezi ethile yokukhipha edingekayo ngokuyilungisa, futhi ithembele emandleni e-medium ngokwayo ukugcina ingcindezi yokukhipha izinzile ngokuzenzakalelayo.
Ukuguquguquka kwengcindezi yokungena kwevalvu yokunciphisa ingcindezi kufanele kulawulwe ngaphakathi kuka-80% - 105% wenani elinikeziwe lengcindezi yokungena. Uma idlula leli banga, ukusebenza kwe-ivalvu yokunciphisa ingcindezikuzothinteka.
1. Ngokuvamile, ingcindezi engezansi ngemva kokunciphisa akufanele ibe ngaphezu kwezikhathi ezingu-0.5 zengcindezi engenhla
2. Intwasahlobo yegiya ngalinye levalvu yokunciphisa ingcindezi isebenza kuphela ngaphakathi kobubanzi obuthile bengcindezi yokuphuma, futhi intwasahlobo kufanele ishintshwe uma ingaphezu kobubanzi.
3. Uma izinga lokushisa lemidiya liphezulu, i-valve yokusiza umshayeli noma i-valve evaliwe ngombhobho kufanele ikhethwe ngokujwayelekile.
4. Uma i-medium ingumoya noma amanzi, kufanele kukhethwe i-diaphragm valve noma i-pilot relief valve.
5. Uma i-medium ingumusi, kufanele kukhethwe i-valve yokusiza umshayeli noma i-valve evaliwe nge-bellows.
6. Ivalvu yokusiza ukucindezeleka kufanele ifakwe emapayipini avundlile ukuze kube lula ukusebenza, ukulungiswa kanye nokugcinwa kwayo.
Ngokwezidingo zokusebenzisa, kukhethwa uhlobo kanye nokunemba kwevalvu yokulawula ingcindezi, kanti ububanzi bevalvu bukhethwa ngokuya ngokugeleza okuphezulu kokukhipha. Lapho kunqunywa ingcindezi yokunikezwa komoya yevalvu, kufanele ibe nkulu kunokucindezela okuphezulu kokukhipha okungu-0.1MPa. Ivalvu yokunciphisa ingcindezi ngokuvamile ifakwa ngemuva kwesihlukanisi samanzi, ngaphambi kwenkungu kawoyela noma idivayisi yokusetha, futhi unake ukuthi ungaxhumani ukungena kanye nokukhipha kwevalvu ngokuphambene; lapho ivalvu ingasetshenziswa, ifindo kufanele likhululwe ukuze kugwenywe ukuthi i-diaphragm ivame ukuba ngaphansi kokuguquguquka kwengcindezi futhi ithinte ukusebenza kwayo.
