Iwo matatu marudzi echeki mavharuvhu -wafer check valve, flange pinza cheki vharafu, uye swing cheki vharafu flanged - zvese zvinopa mabhenefiti akasiyana maererano nekushanda uye kushandiswa.
Iyo wafer cheki vharafu inomira kunze kune yayo compact dhizaini uye lightweight kuvaka. Iyi ficha inoita kuti ive sarudzo yakanakira maapplication uko nzvimbo ishoma kana uremu kunetseka. Zvakare, iyo wafer dhizaini inogonesa kuisirwa nyore pakati peflanges, zvichikonzera kudzikiswa kwekuisa nguva uye mutengo.
Theflange isa cheki vharafu inozivikanwa nekuita kwayo kwekuisa chisimbiso. Iyo flange inopinza inoita segaskets pakati pevharuvhu uye flange, kuve nechokwadi chekuchengetedza chisimbiso chinodzivirira chero kuvuza. Hunhu uhu hunoita kuti flange isa cheki vharafu ive yakakwana kune yakakwira-kudzvanya maapplication uko kuchengetedza chisimbiso kuperera kwakakosha.
Pakupedzisira, theswing cheki vharafuinosarudzwa nekuda kwekusiyana kwayo uye kuvimbika. Iyo swinging disc mukati mevharuvhu inobvumira optimal flow control. Iri rudzi rwevhavhavha yekuongorora inonyanya kukodzera kune zvikumbiro apo kudzivirira kwekudzoka shure kwakakosha, sezvo nzira yekushandura inonyatsogadzirisa reverse flow.
