Ivalve yokhuseleko ifakwe kwisixhobo, isitya okanye umbhobho ukukhusela uxinzelelo olugqithisileyo.Xa uxinzelelo kwisitya okanye umbhobho udlula ixabiso elivumelekileyo, i-valve iya kuvula ngokuzenzekelayo ukukhupha i-medium;Xa uxinzelelo lwehla kwixabiso elichaziweyo, i-valve iya kuvala ngokuzenzekelayo.
Ivalve yokhuseleko inokwahlulwa ibe luhlobo olusebenza ngokuthe ngqo kunye nohlobo oluqhutywa ngumqhubi ngokweendlela ezahlukeneyo zokuqhuba.Uhlobo oluthe ngqo luqhutywa ngokuthe ngqo yinkqubo yoxinzelelo kwi-valve inlet.Ngeli xesha, inqoba uxinzelelo oluphakathi phantsi kwe-disc ye-valve ngumthwalo womatshini onikezelwe yintwasahlobo okanye isando esinzima.Uhlobo lokulinga luqhutywa sisakhiwo, esisebenzisa indlela yokukhulula okanye ukusebenzisa amandla okuvala ukuvula okanye ukuvala ivalve yokhuseleko.
Iivalvu zokhuseleko zinokwahlulwa zibe:
1. Ivalve yokhuseleko lohlobo lwasentwasahlobo
Sebenzisa amandla entwasahlobo yoxinzelelo ukulinganisa uxinzelelo lwediski yevalve, ukuze ivalve yokhuseleko ivalwe.I-valve yokhuseleko ineenzuzo zokuvalelwa okuphezulu, ukuphatheka kunye nendawo yokufakela okungenamkhawulo.Olu hlobo lwevalve yokhuseleko lusetyenziswa ngokuqhelekileyo.Ukungalungi kukuba ukunyanzeliswa kwamandla entwasahlobo kuyatshintsha kunye nokuguqulwa kwentwasahlobo.Xa iqondo lobushushu liphezulu, intwasahlobo ine-insulation yobushushu kunye neengxaki zokutshatyalaliswa kobushushu.
2. I-Lever kunye ne-valve yokhuseleko lwehamile enzima
Amandla ehamile enzima akhuliswa yi-lever kwaye alayishwe kwi-disc valve.Inzuzo kukuba amandla alayishwe kwi-disc ye-valve ahlala engatshintshi ngexesha lokuvula nokuvalwa kwe-valve.Ububi kukuba inovakalelo kwi-vibration kwaye inokusebenza kakubi kwakhona.Ngokuqhelekileyo isetyenziswe kwizixhobo ezisisigxina.
3. Ivalve yokhuseleko lohlobo lwePulse
Ivalve engundoqo kunye nevalve encedisayo ziyilelwe kunye ukuze ziqhube ivalve ephambili ngentshukumo ye-pulse yevalve encedisayo.Isetyenziswa ngokuqhelekileyo kububanzi obukhulu, ukufuduka okukhulu kunye neenkqubo zoxinzelelo oluphezulu.
