Ivalve yokulawula iHydraulic yivalve elawulwa ngoxinzelelo lwamanzi, eyenziwe yivalve engundoqo kunye ne-conduit yayo eqhotyoshelweyo, ivalve yokulinga, ivalve yenaliti, ivalve yebhola kunye negeyiji yoxinzelelo.Ngokweenjongo ezahlukeneyo, imisebenzi kunye neendawo, inokuphuhliswa ibe yi-valve yokulawula ukude, ivalve yokunciphisa uxinzelelo, ivalve yokuvala ngokukhawuleza, ivalve yokulawula ukuhamba, ivalve yokunciphisa uxinzelelo, ivalve yokulawula umbane, njl.
Iivalvu zokulawula i-hydraulic zahlulwe ngohlobo lwe-diaphragm kunye nohlobo lwepiston.Imigaqo yabo yokusebenza iyafana.Banikwa amandla ngumahluko woxinzelelo phakathi kweendawo eziphezulu kunye nezisezantsi kwaye zilawulwa yivalve yokulinga, ukwenzela ukuba i-diaphragm (piston) i-hydraulic differential operation ingalungiswa ngokuzenzekelayo ngoxinzelelo lwe-hydraulic, ukwenzela ukuba i-disc ye-valve engundoqo inokuvulwa ngokupheleleyo. okanye ivalwe ngokupheleleyo okanye ikwimeko yohlengahlengiso.Xa ukunyanzeliswa kwamanzi angena kwigumbi lokulawula ngaphezu kwe-diaphragm (piston) ikhutshwe kwi-atmosphere okanye kwindawo ephantsi yoxinzelelo oluphantsi, ixabiso loxinzelelo elisebenza phantsi kwe-disc ye-valve kwaye ngaphantsi kwe-diaphragm inkulu kunexabiso loxinzelelo olungentla, ke ngoko tyhala idiski yevalve engundoqo kwindawo evuleke ngokupheleleyo;Xa amanzi oxinzelelo angena kwigumbi lokulawula ngaphezu kwe-diaphragm (piston) ayikwazi ukukhutshwa emoyeni okanye kwindawo ephantsi yoxinzelelo oluphantsi, ixabiso loxinzelelo ngaphezu kwe-diaphragm (piston) likhulu kunexabiso loxinzelelo olungezantsi, ngoko ke i-disc ye-valve engundoqo. iya kucinezelwa kwindawo evaliweyo ngokupheleleyo;Xa ixabiso loxinzelelo kwigumbi lokulawula ngaphezu kwe-diaphragm (piston) liphakathi koxinzelelo lwe-inlet kunye noxinzelelo lwe-outlet, i-disc ye-valve engundoqo ikwimeko yokulawula, kwaye indawo yayo yokulawula ixhomekeke kumsebenzi odibeneyo wokulawula i-valve yenaliti ivelufa yokulinga ehlengahlengiswayo kwisixokelelwano sombhobho.Ivalve yokuqhuba ehlengahlengiswayo inokuvula okanye ivale izibuko layo elincinci levalve ngoxinzelelo lokuphuma ezantsi kunye notshintsho lwayo, ukuze utshintshe ixabiso loxinzelelo lwegumbi lokulawula ngaphezulu kwediaphragm (piston) kunye nokulawula indawo yohlengahlengiso lwediski yesikwele sevalve. .
