Mvura yekuongorora valve, inozivikanwawo secheki valve, check valve, counterflow valve, ivhavha inovhura uye inovhara zvichienderana nekuyerera kwepakati pachayo. Basa guru revhavha yecheki nderokudzivirira kudzoka shure kwepakati, kudzivirira kutendeuka kwepombi uye motokari yemotokari, pamwe chete nekudonhedzwa kwemidziyo yemidziyo, uye kuchengetedza kuchengetedzwa kwepombi system nemidziyo.

Diki cheki mavharuvhuinogona kunyanya kukamurwa kuita swing cheki mavharuvhu (inotenderera zvichienderana nepakati pegiravhiti) uye simudza cheki mavharuvhu (achifamba achitevedza axis). Cheki mavharuvhu anogona kuiswa kune mapaipi eakasiyana midhiya zvichienderana nezvinhu. Chimiro chekushanda chevhavhavha yecheki ndechokuti mutoro unoshanduka zvikuru, kuzarura nekuvhara nguva yakawanda, uye kutenderera kwekushandiswa kwakareba kwazvo kana kuchiiswa munzvimbo yakavharwa kana yakazaruka, uye zvikamu zvinofamba hazvidiwi kufamba.

Sezvo iyo mbiri yeplate cheki chevhavha inoshandiswa pakuvhara nekukurumidza mukushandiswa kwakanyanya, uye nguva iyo yevhavha yekuvhara yakavharwa, iyo yepakati iri kuyerera munzira, nevhavha yakavharwa, yepakati inokurumidza kudonha kubva pahupamhi hwekudzokera kumashure kusvika zero, uye kudzvinyirirwa kunokurumidza kusimuka, ndiko kuti, "nyundo yemvura" chiitiko chinogona kuva nemigumisiro inoparadza pane pipeline system. Kune yakakwirira yekumanikidza pombi masisitimu ane akawanda mapombi akafanana, dambudziko resando yemvura yecheki mavharuvhu rinonyanya kuoneka.

Sando yemvura imhando yekumanikidza kwemafungu mukuyerera kwenguva pfupi mupombi yekumanikidza. I hydraulic shock phenomenon yekusvetukira kusvetuka kana kudonha kunokonzerwa nekushanduka kweiyo fluid velocity mupombi yekumanikidza. Chikonzero chemuviri chigumisiro chechiitiko chakabatanidzwa chekusagadzikana kwemvura, inertia yekufamba kwemvura uye elasticity yepombi. Kuti udzivise njodzi yakavanzika yenyundo yemvura mupombi, nekufamba kwemakore, mainjiniya vakashandisa zvimwe zvivakwa zvitsva uye zvinhu zvitsva mukugadzira dhizaini.Stainless simbi cheki vharafukuderedza kukanganiswa kwesando yemvura paunenge uchiona kushanda kunoshanda kwevhavha yekuongorora.

Jinbin valve ine makore makumi maviri ehunyanzvi hwekugadzira mavharuvhu, vagadziri veinjiniya vakanakisa uye vashandi vekugadzira, mavharuvhu emhando inorumbidzwa zvakanyanya. Isu ticharamba tichipa yakanyatsokodzera chirongwa chekutenga mavharuvhu kune vatengi vanoshaya, uye tinotarisira kubatirana kwakawanda!
