Hydraulic njira imodzi yolumikizira pulagi-mu cheke valavu CCV10-20

Check valve (yomwe imadziwikanso kuti check valve) imatanthawuza valavu yomwe imatsegula ndi kutseka diski malingana ndi kutuluka kwa sing'anga yokha kuti ateteze sing'angayo kuti isabwerere kumbuyo, yomwe imadziwikanso kuti check valve, valve ya njira imodzi, reverse flow valve. ndi valavu yothamanga kumbuyo.Chongani valve ndi valavu yokhayokha, ntchito yake yaikulu ndikuletsa sing'anga kuti isabwerere kumbuyo, kuteteza mpope ndi galimoto yoyendetsa galimoto kuti isabwerere, ndikumasula sing'anga mu chidebecho.Ma valve owunika atha kugwiritsidwanso ntchito m'mapaipi omwe amapereka machitidwe othandizira momwe kupanikizika kumatha kukwera pamwamba pa kuthamanga 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).

1. Valavu yosabwerera: valve yoyang'ana yomwe disc yake imazungulira kuzungulira pini pampando wa valve.Vavu yoyang'ana ma disc ndiyosavuta kupanga ndipo imatha kuyikidwa paipi yopingasa, chifukwa chake imakhala ndi ntchito yabwino yosindikiza.

2. Chidutswa cha valavu choyang'ana chimakhala chofanana ndi disc ndipo chimazungulira kuzungulira shaft yozungulira ya mpando wa valve.Chifukwa njira mu valavu ndi streamlined, kukana kuyenda ndi yaying'ono kuposa agulugufe cheke valavu.Ndi yoyenera pazochitika zazikuluzikulu zomwe zimakhala ndi kutsika kochepa komanso kusintha kosasinthasintha, koma sikoyenera kugwedeza, ndipo kusindikiza kwake sikuli bwino mofanana ndi mtundu wokweza.Ma valve oyang'ana agulugufe amagawidwa m'mitundu itatu: single-flap, double-flap ndi multi-flap.Mitundu itatuyi imagawidwa makamaka molingana ndi kavalo wa valve, pofuna kuteteza sing'anga kuti isayime kuyenda kapena kubwerera kumbuyo ndikufooketsa mphamvu ya hydraulic.
