Vavu yoyang'ana imatanthawuza valavu yomwe gawo lake lotsegula ndi lotseka ndi valavu yozungulira, yomwe imagwira ntchito molingana ndi kulemera kwake ndi kupanikizika kwapakati kuti atseke kumbuyo kwapakati.Ndi valve yodziwikiratu, yomwe imadziwikanso kuti valavu yoyendera, valavu yanjira imodzi, valavu yobwerera kapena valavu yodzipatula.Mayendedwe a disc amagawidwa kukhala mtundu wokweza ndi mtundu wa swing.Valve yowunikira ndi yofanana ndi valavu yapadziko lonse lapansi, kupatula kuti ilibe tsinde la valve kuti liyendetse diski.Sing'anga imayenda kuchokera ku doko lolowera (mbali yakumunsi) ndikutuluka kuchokera padoko (mbali yakumtunda).Pamene kulowetsedwa kolowera kuli kwakukulu kuposa kuchuluka kwa kulemera kwa disc ndi kukana kwake, valve imatsegulidwa.Mosiyana ndi zimenezi, valve imatsekedwa pamene sing'anga imayenda chammbuyo.Chovala choyang'ana cha swing chili ndi diski ya oblique yomwe imatha kuzungulira mozungulira, ndipo mfundo yake yogwira ntchito ndi yofanana ndi ya valve yokweza.Valve yowunikira nthawi zambiri imagwiritsidwa ntchito ngati valavu pansi pa chipangizo chopopera kuti madzi asabwererenso.Kuphatikiza kwa valavu ya cheki ndi valavu yapadziko lonse lapansi kumatha kutenga gawo lodzipatula.Ma valve owunika ali m'gulu la ma valve odzichitira okha, ndipo amagwiritsidwa ntchito makamaka pamapaipi omwe ali ndi njira imodzi yokha, ndipo amangolola sing'anga kuyenda mbali imodzi kuti apewe ngozi.
Ma valve owunika amagwiritsidwanso ntchito pamizere yomwe imapereka machitidwe othandizira pomwe kupanikizika kumatha kukwera pamwamba pa kukakamiza kwa dongosolo.Ma valve owunikira amatha kugawidwa makamaka kukhala ma valve cheke (ozungulira molingana ndi pakati pa mphamvu yokoka) ndi ma valve okweza (akuyenda mozungulira).
Ntchito ya valve yowunika ndikungolola kuti sing'angayo iziyenda mbali imodzi ndikuletsa kuyenda kosiyana.Nthawi zambiri valavu yamtunduwu imagwira ntchito yokha.Pansi pa mphamvu yamadzimadzi yomwe ikuyenda mbali imodzi, chimbale cha valve chimatsegulidwa;pamene madzi akuyenda mosiyana, mpando wa valve umagwiritsidwa ntchito ndi kuthamanga kwa madzi ndi kudzilemera kwa diski ya valve kuti athetse kutuluka.
Ma valve owunikira amaphatikizanso ma valve oyendera ndi ma valve okweza.Valavu yoyang'ana pa swing ili ndi makina a hinge, ndipo diski yonga chitseko imatsamira momasuka pampando wokhazikika.Pofuna kuonetsetsa kuti valavu ya valve imatha kufika pamalo abwino a mpando nthawi zonse, valavu ya valve imapangidwira mu hinge mechanism, kotero kuti valavu ya valve imakhala ndi malo okwanira osambira, ndipo imapangitsa kuti valavu ikhale yogwirizana komanso yogwirizana kwambiri. mpando wa valve.Chimbalecho chikhoza kupangidwa ndi chitsulo chonse, kapena chikhoza kuikidwa ndi chikopa, mphira, kapena chophimba chopangira pazitsulo, malingana ndi zofunikira za ntchito.Pamene valavu yotsegula yotsegula imatsegulidwa kwathunthu, kuthamanga kwamadzimadzi kumakhala kosalekeza, kotero kuti kuthamanga kutsika kudzera mu 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 ili ngati valavu ya globe.Kuthamanga kwamadzimadzi kumapangitsa kuti diski ya valve ikwezedwe kuchokera pamwamba pa chisindikizo cha 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 mawonekedwe a mphira kapena mphete ya mphira yomwe imayikidwa pa disk frame.Mofanana ndi valavu yoyimitsa, njira yamadzimadzi kudzera muzitsulo zoyendetsa galimoto imakhalanso yopapatiza, kotero kuti kuthamanga kutsika kupyolera muzitsulo zoyendetsa galimoto ndi zazikulu kuposa za valve check valve, ndipo kuthamanga kwa valve check valve ndi kochepa.osowa.
Gulu la Check Valves
Malinga ndi kapangidwe kake, valavu yoyang'ana imatha kugawidwa kukhala valavu yokweza, valavu yoyendera ndi valavu yagulugufe.Mitundu yolumikizira ya ma cheke awa imatha kugawidwa m'mitundu inayi: kulumikizana kwa ulusi, kulumikiza kwa flange, kulumikizidwa kowotcherera ndi kulumikiza kopindika.
Malinga ndi nkhaniyi, valavu yowunikira imatha kugawidwa kukhala valavu yoyang'ana chitsulo, valavu yamkuwa, valavu yachitsulo chosapanga dzimbiri, valavu yoyang'ana zitsulo za carbon ndi valve yopangira zitsulo.
Malingana ndi ntchitoyi, valve yowunikira ikhoza kugawidwa mu DRVZ silent check valve, DRVG silent check valve, NRVR silent check valve, SFCV rubber disc check valve ndi DDCV double disc check valve.
