Kodi ma check valve amagwira ntchito bwanji?

Onani ma valveZitha kugwiritsidwanso ntchito pamizere yopereka makina othandizira pomwe kupanikizika kumatha kukwera kuposa kukakamiza kwadongosolo. Ma valve owunikira amatha kugawidwa makamaka kukhala ma valve oyendera (ozungulira molingana ndi pakati pa mphamvu yokoka) ndikukweza ma cheke (akuyenda mozungulira).
Cholinga cha valavu yamtunduwu ndikulola kuti sing'angayo iziyenda njira imodzi yokha ndikuletsa kuyenda mosiyana. Nthawi zambiri valavu yamtunduwu imagwira ntchito yokha. Pansi pa mphamvu yamadzimadzi yomwe ikuyenda mbali imodzi, valavu ya valve imatsegulidwa; pamene madzi amadzimadzi akuyenda kumbali ina, kuthamanga kwamadzimadzi ndi kutsekemera kwapadera kwa valve ya valve kumapanga pampando wa valve, motero kumadula kutuluka.
Pakati pawo, valavu ya cheke ndi ya mtundu uwu wa valve, womwe umaphatikizapovalavu yoyenderandi kukweza valve cheke. Ma valve a swing check ali ndi makina a hinge ndi chimbale chokhala ngati chitseko chomwe chimakhazikika momasuka pampando wotsetsereka. Pofuna kuonetsetsa kuti diski ya valve imatha kufika pamalo oyenera a mpando wa valve nthawi zonse, diski ya valve imapangidwa mu makina a hinge, kotero kuti diski ya valve ikhale ndi malo okwanira osambira ndipo imapangitsa kuti diski ya valve ikhale yeniyeni komanso yogwirizana ndi mpando wa valve. Diski ikhoza kupangidwa ndi chitsulo chonse, kapena yokutidwa ndi chikopa, mphira, kapena zokutira zopangira, malingana ndi zofunikira za ntchito. Pamalo otseguka a valavu ya swing check, kuthamanga kwamadzimadzi kumakhala kosalephereka, kotero kutsika kwapakati pa valve kumakhala kochepa. Diski ya valavu yokweza yokwera ili pamtunda wosindikizira wa mpando wa valve pa thupi la valve. Kupatula kuti valavu ya valve imatha kuwuka ndikugwa momasuka, valavu yotsalayo imakhala ngati valavu ya globe. Kuthamanga kwamadzimadzi kumakweza diski ya valve kuchokera kumalo osindikizira a mpando wa valve, ndipo kubwerera kumbuyo kwa sing'anga kumapangitsa kuti diski ya valve ibwerere ku mpando wa valve ndikudula kutuluka. Malinga ndi momwe amagwiritsidwira ntchito, chimbalecho chikhoza kukhala chazitsulo zonse, kapena chikhoza kukhala ngati mphira wa rabara kapena mphete ya mphira yomwe ili pa chotengera cha disc. Mofanana ndi valavu yapadziko lonse lapansi, kutuluka kwa madzi kudzera muzitsulo zoyendetsa galimoto kumakhalanso kochepa, kotero kuti kuthamanga kutsika kupyolera muzitsulo zoyendetsa galimoto ndi zazikulu kuposa za valve yoyang'ana swing, ndipo kutuluka kwa valve check check valve kumakhala kochepa.
