Chii Chinosiyana Pakati Pekusadzoka neValve Yekutarisa

Paunenge uchishanda nemapombi, unogona kazhinji kunzwa zvese zviri zvivirivharuvhu isingadzore (NRV)uyevharuvhu yekutarisakushandiswa. Pakutanga, zvinganzwika semavharuvhu maviri akasiyana. Asi akafanana zvechokwadi here? Kana kuti pane musiyano wakakodzera kucherechedzwa here? Ngatizvitsanangure nemashoko akareruka.

Chii chinonzi Non Return Valve (NRV)?

Vharuvhu isingadzokeri imhando yevharuvhu inobvumira mvura—ingava mvura kana gasi—kuyerera nenzira imwe chete. Kana mvura yamira kana kuedza kudzokera shure, vharuvhu inovhara yega. Basa iri rinodzivirira kudzokera shure, izvo zvinogona kukuvadza michina kana kusvibisa nzvimbo yakachena.

MaNRV anoshandiswa zvakanyanya mu:Masisitimu emvura ekudzivirira kusvibiswa.Mapombi ekumisa kufamba kwemvura kana pombi yadzimwa.Mapaipi emaindasitiri uko kuchengetedza kufamba kwemvura nenzira imwe chete kwakakosha.

Chinhu chikuru chiri nyore: NRV inoita kuti mvura iende mberi uye isadzoke shure.

Chii chinonzi Check Valve

Vharuvhu yekuchekesa inoshanda nepfungwa imwecheteyo. Inomisawo kuyerera kwemvura uye inoita kuti mvura ifambe nenzira imwe chete. Vharuvhu yekuchekesa inowanikwa muindasitiri dzese, kubva pakuchenesa mvura kusvika kumafuta negasi.

Kune mhando dzakasiyana dzemavharuvhu ekuongorora, dzakadai se:Mavharuvhu ekuongorora kutenderera (ane dhisiki ine hinged inotenderera ichivhurika kana kuvharika).Mavharuvhu ekuongorora kusimudza (dhisiki inosimudzwa kumusoro kana pasi nekuyerera).Mavharuvhu ekuongorora bhora (bhora rinoshanda senzira yekuvhara).Mavharuvhu ekuongorora mawafer (dhizaini diki yenzvimbo dzakamanikana).

Saka, Musiyano Chii?

Apa ndipo panotanga kunakidza zvinhu. Chokwadi ndechekuti: vharuvhu isingadzoreri nevharuvhu yekutarisa zvinhu zvakafanana. Musiyano mukuru uri mumashoko anoshandiswa.

• Vharuvhu isingadzore (NRV) izwi rinowanzo shandiswa kana kuti rinotsanangura, rinowanzoshandiswa muChirungu cheBritish uye mumaindasitiri ane chekuita nemvura.

• Izwi rekuti Check valve ndiro rinoshandiswa zvakanyanya, kunyanya muChirungu chekuAmerica uye mumamiriro ezvinhu eindasitiri kana emakanika.

Saka, kana mumwe munhu achiti NRV, anenge achitaura nezvechinhu chimwe chete icho mumwe munhu angati check valve. Zvese zvine chinangwa chimwe chete: kudzivirira kudzokera shure kwemvura.
