300X Ivalve yokujonga ukuvala kancinane

Iimpawu zeMveliso I-valve yokutshekisha yenziwe yi-valve ephambili kunye ne-valve yokulawula yangaphandle. Kukho amagumbi amabini amanzi kwivalve ephambili, kwaye igumbi lamanzi le-diaphragm ligumbi lokulawula uxinzelelo. Xa impompo yamanzi iyeka ukusebenza, ngenxa yobunzima bobuqu bediski yevalve, amandla omthombo wevalve engundoqo kunye namandla omahluko woxinzelelo phakathi kwegumbi eliphezulu kunye negumbi elisezantsi (xa impompo yamanzi iyeka ukusebenza, uxinzelelo kwindawo esezantsi. igumbi liyancipha ngokukhawuleza, kodwa uxinzelelo olukwigumbi eliphezulu luyancipha ngokukhawuleza), i-valve plate ivalwe ngokukhawuleza i-90%, kwaye i-10% eseleyo idluliselwa kwigumbi eliphezulu ngombhobho wesikhokelo. Ngokunyuka koxinzelelo kwigumbi eliphezulu, i-valve flap ithathwa ukuvala i-port yokuvala I-10% eseleyo yokuvula idlala indima yokunciphisa ingxolo kunye nokunciphisa isando samanzi. 1. Kufuneka ifakwe ngokuthe tye 2. Ngaphambi kofakelo, i-sundries ngaphakathi kwinethiwekhi yombhobho iya kucocwa ukuze kuqinisekiswe ukuhamba okuguquguqukayo kwe-valve core 3. Ivalve yokumisa enobubanzi obuhambelanayo iya kufakwa kwindawo apho umthombo wamanzi unokuba khona. ukunqunyulwa xa i-valve yokutshekisha ingagcinwa 4. Ivalve yokukhangela iya kugcinwa icocekile ngaphakathi ngaphambi nangexesha lokuthunyelwa kombhobho wombhobho, kwaye ayiyi kungena kwiindawo ezihlukeneyo ngenxa yokwakhiwa okungafanelekanga 5. Ukugunyaziswa: xa i-valve ishiya umzi-mveliso, ivalve yenaliti kunye nevalve yebhola zonke zivaliwe. Sebenzisa ivalve ukujikelezisa izangqa ezi-2 kunye nesiqingatha ngokunxamnye newotshi, kwaye ivalve yebhola ivuleke ngokupheleleyo. Ukuba ihamile yamanzi ifunyenwe, ivalve encinci yebhola inokuvaleka kancinane, kwaye ivalve yesitofu inokuvulwa kancinane ngokuchasene newotshi ukuphelisa ihamile yamanzi.
