Chii chinonzi Ball Check valve?
Cheki vharafu imhando yevharuvhu kune uni-directional chinangwa, zvakare seasingadzoke mavharuvhu.
ABhora Cheka Valveivharuvhu iri nyore uye yakavimbika ine bhora rakatenderera sechikamu chega chinofamba chinovhara kuyerera kwereverse.Nekuda kwekuyerera kwayo kuri nyore uye kunenge kusingatarisike-isina dhizaini inowanzotsanangurwa uye inoshandiswa munzvimbo dzepasi pemvura yetsvina.Kune vacuum kana anti-flooding valve application, bhora "rinoyerera" pane "kunyura" rinoshandiswa.
Bhora cheki mavharuvhuine bhora rinogara pachigaro, rine buri rimwe chete.Inoshanda ichishandisa bhora rinokwira nekudzika mukati mevharuvhu.Chigaro chinogadzirwa kuti chikwane bhora, uye chamber yacho yakanyatsoumbwa kuti itungamirire bhora pachigaro kuti rivhare uye kumisa reverse flow.Bhora rine dhayamita yakati kurei kupfuura yeburi reburi (seat).Kana dzvinyiriro iri kuseri kwechigaro ichipfuura iyo iri pamusoro pebhora, mvura inotenderwa kuyerera nemuvharuvhu.Asi kana kudzvanywa kuri pamusoro pebhora kuchinge kwapfuura kudzvanya kuri pasi pechigaro, bhora rinodzokera kuzozorora pachigaro, richigadzira chisimbiso chinodzivirira kuyerera.Bhora rinofamba richikwira nekudzika mukati mevharuvhu zvichienderana nekuyerera uye zvisimbiso zvichitarisana nechigaro chakagadzirwa kana pasina kuyerera kana kutenderera kunoitika uye kuvharira chigaro kuti kumisa kuyerera kwemashure.cheki mavharuvhu ane Buna-N mutsara bhora seyakajairwa uye ine corrosion-resistant phenolic balls for abrasive media.Bhora cheki mavharuvhu anowanzo kusarudzwa kuti ashandiswe mukupomba zviteshi sezvo ari kuzvichenesa sezvo bhora rinotenderera panguva yekuvhiya uye rakamira rakamira-risina.Kana cheki yebhora ichiita ruzha inowanzokonzerwa nekusakwana kwepombi kana nyaya dzesando dzemvura.
