Vavu yoyang'ana imatanthawuza valavu yomwe imatsegula ndi kutseka valavu ya valve kutengera kuthamanga kwa sing'angayo kuti sing'angayo isabwererenso.Imatchedwanso valavu yoyendera, valavu yanjira imodzi, valavu yobwerera kumbuyo, ndi valavu yakumbuyo.Ntchito ya cheki valve ndi
Valve yowunikira ndi mtundu wa valve yodziwikiratu, ntchito yake yayikulu ndikuletsa kutuluka kwapakati kwa sing'anga, kuteteza mpope ndi mota yoyendetsa kuti zisabwerere, komanso kutulutsa kwapakati pa chidebe.Chekecho chingagwiritsidwenso ntchito popereka mapaipi a machitidwe othandizira pomwe kupanikizika kumatha kukwera pamwamba pa kukakamiza kwa dongosolo.
Kugawika kwa ma cheki ma valve
Malinga ndi kapangidwe kake ndi njira yoyika, valavu yoyang'anira ingagawidwe kukhala:

1. Valavu yoyang'ana swing
Diski ya valavu yoyang'ana swing imakhala yofanana ndi disc ndipo imazungulira mozungulira tsinde la mpando wa valve.Chifukwa ndimeyi mu valavu imayendetsedwa bwino, kukana koyenda kumakhala kochepa kuposa kwa valve yokweza.Ndizoyenera kutsika kochepa komanso ma valve osabwerera.Nthawi zazikuluzikulu zokhala ndi zosintha pafupipafupi, koma sizoyenera kutulutsa, komanso kusindikiza kwake sikuli bwino ngati mtundu wonyamulira.Mavavu oyendera ma swing amagawidwa m'mitundu itatu: valavu imodzi, valavu iwiri ndi theka valavu.Mitundu itatuyi imayikidwa makamaka molingana ndi ma valve awiri.Cholinga chake ndikuletsa sing'anga kuti isayime kapena kuyenderera chammbuyo ndikufooketsa ma hydraulic shock.

2. Kwezani valavu yowunika
Valve yowunika yomwe chimbale chake chimayenda pakatikati pakatikati pa thupi la valve.Valve yowunikira imatha kukhazikitsidwa papaipi yopingasa, ndipo mpira wozungulira ungagwiritsidwe ntchito pa diski yayikulu pa valavu yoyang'ana yaing'ono yaing'ono.Maonekedwe a thupi la valve ya valve yokweza ndi yofanana ndi valve yoyimitsa (yomwe ingagwiritsidwe ntchito mofanana ndi valavu yoyimitsa), kotero kuti mphamvu yake yamadzimadzi imakhala yaikulu.Mapangidwe ake ndi ofanana ndi valve yoyimitsa, ndipo thupi la valve ndi disc ndilofanana ndi valve yoyimitsa.Kumtunda kwa diski ya valve ndi kumunsi kwa chivundikiro cha valve kumakonzedwa ndi manja otsogolera.Manja owongolera ma disc amatha kuwuka ndikugwa momasuka m'manja owongolera a valve.Pamene sing'anga imayenda kunsi kwa mtsinje, ma valve discs amatsegulidwa ndi kukankhira kwa sing'anga.Sing'anga ikasiya, ma disc a valve amadalira okha Iwo amagwera pampando wa valve kuti ateteze sing'angayo kuti isabwerere chammbuyo.Chitsogozo cha njira yolowera pakati ndi njira yotulutsira ya valve yowongoka-kudutsa ndi yolunjika kumayendedwe a mpando wa valve;valavu yoyang'ana yokwera imakhala ndi njira yofanana ndi njira yolowera ndi yotuluka ngati njira ya mpando wa valve, ndipo kukana kwake kothamanga kumakhala kochepa kusiyana ndi mtundu wowongoka.

3. Valve yowunikira ma disc
Valve ndi valavu yoyang'ana yomwe imazungulira kuzungulira shaft ya pini pampando wa valve.Valve yoyang'ana ma disc ili ndi mawonekedwe osavuta ndipo imatha kukhazikitsidwa paipi yopingasa, osasindikiza bwino.

4. Vavu yoyang'ana pamzere
Valavu ndi valve yomwe imayendayenda pakati pa thupi la valve.Valavu yoyang'ana pamzere ndi mtundu watsopano wa valve.Ndi yaying'ono kukula kwake, yopepuka kulemera, komanso yabwino pakukonza ukadaulo.Ndi imodzi mwa njira zachitukuko za ma valve cheke.Komabe, coefficient of fluid resistance ndi yaikulu pang'ono kuposa ya swing check valve.
5. Valavu yowunikira kupanikizika
Valavu yamtunduwu imagwiritsidwa ntchito ngati madzi opangira boiler ndi valavu yotsekera nthunzi, imakhala ndi ntchito yokwanira yowunikira valavu ndi valavu yoyimitsa kapena valavu.
