Petroleum & Petrochemical Check Valve
Mawonekedwe
Ntchito ya swing check valve iyi ndiyo kulola sing'anga kuyenda njira imodzi yokha, ndikuyimitsa kutuluka kumbali ina.Kawirikawiri, valve imagwira ntchito yokha.Pansi pa mphamvu yamadzimadzi yomwe ikuyenda mbali imodzi, valve clack imatsegulidwa.Madzi amadzimadzi akamadutsa mbali ina, tanki yosinthira imagwira pampando wosinthira ndi kuthamanga kwamadzimadzi komanso kulemera kwa chowongolera chowongolera kuti achepetse kutuluka.
Chovala choyang'ana cha swing chimakhala ndi makina a hinge, ndipo valavu ngati chitseko imakhala momasuka pampando wokhazikika wa valve.Pofuna kuonetsetsa kuti phokoso la valve likhoza kufika pamalo oyenera pampando wa ukonde nthawi zonse, phokoso la valve limapangidwira pamakina a hinge, kuti phokoso laulere likhale ndi malo okwanira osambira, ndipo chowongolera chosinthika chimagwirizanitsa bwino mpando wa valve. .Valavu ikhoza kukhala yopangidwa ndi chitsulo, kapena yophimbidwa ndi chikopa, mphira kapena chophimba chopangira pazitsulo, malingana ndi zofunikira za ntchito.Pamene swing check valve yatsegulidwa kwathunthu, kuthamanga kwamadzimadzi kumakhala kosalekeza, kotero kuti kuthamanga kutsika kudzera mu valve kumakhala kochepa.

Ntchito ya valve yokweza iyi ndikulola kuti sing'angayo iziyenda mbali imodzi yokha, ndikuyimitsa kuyenda kwina.Kawirikawiri, valve imagwira ntchito yokha.Pansi pa mphamvu yamadzimadzi yomwe ikuyenda mbali imodzi, valve clack imatsegulidwa.Madzi amadzimadzi akamadutsa mbali ina, tanki yosinthira imagwira pampando wosinthira ndi kuthamanga kwamadzimadzi komanso kulemera kwa chowongolera chowongolera kuti achepetse kutuluka.
Kupatula kuti valavu ikhoza kutsegulidwa ndi kutsika momasuka, valavu yotsalayo ndi yofanana ndi valavu ya globe.Kuthamanga kwamadzimadzi kumakweza valavu ya valve kuchokera pamalo osindikizira a mpando wa valve, ndipo chizindikiro chobwerera chapakati chimapangitsa kuti pini yoyang'anira igwere kumpando wa valve ndikudula kutuluka.Malinga ndi momwe amagwiritsidwira ntchito, kutchingira kumatha kukhala chitsulo chonse, kapena kutha kukhala ngati zopangira mphira kapena mphete za mphira pamawu otumizirana mawu.Monga valavu yapadziko lonse lapansi, njira yamadzimadzi kudzera mu valavu yonyamulira ndi yopapatiza, kotero kukakamiza kwa valavu yonyamulira ndi yayikulu kuposa ya valavu yosinthira.
