CHV150-300
Monga momwe mayina amasonyezera, valavuyi imakhala ndi chipata chogwedezeka chomwe chimakhala pamwamba pake ndipo chimatseguka pamene madzi akudutsa. Ndime yoyenda bwino imaperekedwa ndi swing check valve pamene diski ya valve ili pamalo otseguka. Mkati mwa valavu, njira yosalala iyi imatulutsa chipwirikiti chochepa komanso kuchepa kwamphamvu. Kuti valavu igwire bwino ntchito, payenera kukhala nthawi zonse kupanikizika kochepa kuti mutsegule diski. Pamene kutuluka kwamadzimadzi kumabwereranso, kupanikizika ndi kulemera kwa sing'anga motsutsana ndi diski kumakankhira diski pampando, motero kulepheretsa kubwereranso konse. Ma valve owunika amawonedwa ngati zida zotetezera kapena zoteteza.
Kalasi 150-300 Cast Steel Check Valve ndi valavu ya cheke yopangidwa ndi zitsulo zotayidwa. Imagawidwa m'kalasi 150 ndi kalasi 300 molingana ndi gulu lopanikizika. Zomwe zimapangidwira zimaphatikizira kapangidwe kake, kakulidwe kakang'ono, kulemera kopepuka, ntchito yabwino yosindikiza, komanso ntchito yosavuta. Valavu iyi ndi yoyenera m'malo othamanga kwambiri komanso kutentha kwambiri kuti mupewe kubweza kwamadzimadzi m'mapaipi. Nthawi zambiri amagwiritsidwa ntchito pamapaipi amagetsi m'mafakitale monga petroleum, makampani opanga mankhwala, ndi mphamvu zamagetsi.
Ndi valve yomwe imagwiritsa ntchito rotary kuti iwononge kutuluka kwa madzi. Nthawi zambiri imakhala ndi thupi la valve, chivundikiro cha valve, chivundikiro cha valve, tsinde la valve, ndi chipangizo chogwiritsira ntchito. Valavu yamtunduwu imakwaniritsa kutuluka kwa sing'anga kuti mutsegule kapena kutseka pozungulira diski ya valve, ndipo imakhala ndi ntchito yabwino yosindikiza, yomwe ingalepheretse kutulutsa kwapakati.
