Tsanangudzo yakadzama yevhavhavha yecheki:
Cheki mavharuvhu ndiwo otomatiki mavharuvhu, anonziwo cheki mavharuvhu, imwe-nzira mavharuvhu, kudzoka mavharuvhu kana kuzviparadzanisa mavharuvhu.Kufamba kwe disc kunokamurwa kuva lift type uye swing type.Iyo yekusimudza cheki vharafu yakafanana muchimiro kune yekuvhara-vharavhavha, asi inoshaya tsinga yevharuvhu inotyaira disc.Iyo yepakati inoyerera ichibva kumagumo ekupinza (yezasi side) uye inoyerera ichibuda kubva kunobuda kunogumira (kumusoro divi).Kana iyo inlet pressure yakakura kudarika kuwanda kwehuremu hwe disc uye kuyerera kwayo kupikisa, valve inovhurwa.Pane zvinopesana, valve yakavharwa kana iyo yepakati inoyerera ichidzoka.Iyo swing cheki valve ine dhisiki yakarerekera uye inogona kutenderera yakatenderedza axis, uye iyo nheyo yekushanda yakafanana neyekusimudza cheki valve.Ivhavhavha yekuongorora inowanzoshandiswa sevhavha yepasi yemudziyo wekupomba kudzivirira kuyerera kwemvura.Iko kusanganiswa kwevhavhavha yekutarisa uye yekumisa valve inogona kutamba basa rekuchengetedza kuparadzaniswa.Izvo zvisingabatsiri ndezvokuti kushorwa kwakakura uye kushanda kwechisimbiso kwakashata kana kwakavharwa.
