Inkcazo eneenkcukacha yevalve yokukhangela:
Iivalve zokukhangela zizivalo ezizenzekelayo, ezikwabizwa ngokuba ziivalve zokutshekisha, iivalve zendlela enye, iivalve zokubuya okanye iivalve zokuzahlula.Ukuhamba kwediski kwahlulwe ngohlobo lokuphakamisa kunye nohlobo lwe-swing.Ivalve yokukhangela i-lift ifana nesakhiwo kwi-valve yokuvala, kodwa ayinayo i-valve stem eqhuba i-disc.Indawo ephakathi ingena ukusuka kwindawo yokungena (icala elisezantsi) kwaye iphuma kwindawo yokuphuma (icala eliphezulu).Xa uxinzelelo lwe-inlet lukhulu kunobunzima bobunzima bediski kunye nokuchasana nokuhamba kwayo, i-valve ivuliwe.Ngokuchasene noko, i-valve ivaliwe xa i-medium flowing back.I-valve yokukhangela i-swing ine-disc ethambekele kwaye inokujikeleza kwi-axis, kwaye umgaqo osebenzayo ufana ne-valve yokukhangela i-lift.Ivalve yokukhangela isoloko isetyenziswa njengevalve esezantsi yesixhobo sokumpompa ukuthintela ukuphuma ngasemva kwamanzi.Ukudibanisa i-valve yokukhangela kunye ne-valve yokumisa inokudlala indima yokhuseleko lodwa.Ukungalungi kukuba ukuchasana kukhulu kwaye ukusebenza kokutywinwa kubi xa kuvaliwe.
