API 594 Dual plate check valve imagwiritsidwa ntchito popanga mapaipi angwiro ndi mafakitale, kuteteza chilengedwe, kuyeretsa madzi, madzi ndi ngalande zamapaipi m'nyumba zazitali kuti ateteze kusuntha kwa media. Valavu ya cheke imatenga mtundu wawafe, mbale yagulugufe imakhala ndi semicircles ziwiri, ndipo imatenga kasupe kuti ikakamize kukonzanso, malo osindikizira amatha kukhala ndi thupi lomwe likuyang'anizana ndi zowotcherera zosagwira ntchito kapena mphira, kugwiritsa ntchito kwake kuli kwakukulu, ndi kusindikiza. ndi odalirika.

Magawo otsegula ndi otseka a API 594 check valve amadalira kuthamanga ndi mphamvu ya sing'anga kuti atsegule kapena kutseka okha kuti ateteze sing'anga kubwereranso. Valve imatchedwa cheki valve. Ma valve owunikira ali m'gulu la ma valve odzichitira okha, omwe amagwiritsidwa ntchito kwambiri m'mapaipi pomwe sing'anga imayenda mbali imodzi, ndipo amangolola sing'anga kuyenda mbali imodzi kuti apewe ngozi.

Malinga ndi kapangidwe ka valavu cheke, akhoza kugawidwa mu mitundu itatu: valavu yowunikira, valavu yoyendera ndi valve yoyang'ana pansi. Ma valve okwera amatha kugawidwa m'mitundu iwiri: ofukula ndi yopingasa. Mavavu oyendera ma swing amagawidwa m'mitundu itatu: valavu imodzi, valavu iwiri ndi valavu yambiri. Valve yoyang'ana wafer ndi mtundu wowongoka. Valve yoyendera ndi valavu yomwe imatha kuteteza madzi kuti asabwererenso. Chovala cha valve cha valve chotsegula chimatseguka pansi pa mphamvu yamadzimadzi, ndipo madzi amadzimadzi amayenda kuchokera kumbali yolowera kupita ku mbali yotulukira. Pamene kupanikizika kumbali yolowera kumakhala kotsika kusiyana ndi komwe kumatuluka, valavu ya valve imatsekedwa pokhapokha pansi pa kusiyana kwa kuthamanga kwa madzi, mphamvu yokoka ndi zinthu zina kuti madzi asabwererenso.

Ngati mukufuna zambiri za mavavu chonde lemberani dipatimenti yogulitsa ya NSW(newsway valve).
