Tarisa vharafuinonziwonzira imwe vharafukana cheki vharafu, basa rayo nderekudzivirira svikiro riri mupombi kuti rirege kuyerera richidzoka.Ivhavha inovhura kana kuvhara yega nekuyerera uye simba repakati kudzivirira pakati kubva kuyerera kumashure inonzi cheki valve.Cheki mavharuvhu ndeechikamu cheotomatiki mavharuvhu.Cheki mavharuvhu anonyanya kushandiswa mumapaipi apo svikiro inoyerera munzira imwe, uye inongobvumira svikiro kuti riyerere munzira imwe kudzivirira tsaona.
Zvinoenderana nechimiro chevhavhavha yekutarisa, inogona kukamurwa kuva marudzi matatu:simudza cheki valve, swing check valveuyebutterfly cheki vharafu.Simudza cheki mavharuvhu anogona kukamurwa kuva marudzi maviri:vertical cheki mavharuvhuuyehorizontal cheki mavharuvhu.Iyo swing cheki valve yakakamurwa kuva marudzi matatu:single plate check valve, kaviri ndiro cheki vharafuuye multi-plate check valve.
Zvinhu zvinotevera zvinofanirwa kutariswa kana uchiisa cheki valve:
1.Usabvumira kuti cheki valve itakure uremu mupombi.Mavharuvhu makuru ekutarisa anofanirwa kutsigirwa akazvimirira kuitira kuti arege kukanganiswa nekumanikidzwa kunoitwa nepiping system.
2.Paunenge uchiisa, teerera kune kutungamira kwekuyerera kwepakati kunofanirwa kuenderana nekutungamira kwemuseve wakanyorwa pamutumbi wevharuvhu.
3.Kusimudza vertical flap cheki vharafuinofanira kuiswa papombi yakatwasuka.
4.Thesimudza mhando horizontal flap cheki vharafuinofanira kuiswa pahorizontal pipeline.
Kufunga nezvekuisa:
1.Paunenge uchiisa pombi, teerera kuti uite nzira yekupfuura ye wafer check valveinopindirana negwara rekuyerera kwemvura, Yakaiswa mupombi yakatwasuka;Pamapaipi akachinjika, isa wafer cheki vharuvhu yakatwasuka.
2.Shandisa telescopic tube pakati pewafer check valve uye butterfly valve, usambozvibatanidza zvakananga kune mamwe mavharuvhu.
3.Dzivisa kuwedzera majoini epombi uye zvipingamupinyi mukati mehutano hwekushanda kweplate yevhavha.
4.Usaisa reducer pamberi kana shure kwewafer check valve.
5.Paunenge uchiisa cheki chekivhavha yakatenderedza pagokora, teerera pakusiya nzvimbo yakakwana.
6.Paunenge uchiisa cheki chekivhavha panzvimbo yepombi, siya nzvimbo inokwana katanhatu dhayamita yevharuvhu kuti uone kuti butterfly plate inopedzisira yakanganiswa nemvura.
