Ndiyenera kuchita chiyani ngati valavu ya cheki singayimitse madzi?

Sindingathechekeni valavukuletsa madzi? Njirazi zidzakuthandizani kuthetsa

Ma valve owunikira akuyenera kukhala "oteteza okhulupirika" kuti ateteze kubweza kwa madzi, koma akalephera kuyimitsa madzi, zitha kuyambitsa mavuto ambiri. Komabe, musadandaule, titha kufufuza ndikuthetsa vutoli kuchokera kuzinthu zingapo.

Ndondomeko yoyika iyenera kufufuzidwa kaye.Onani mavavukhalani ndi zizindikiro zomveka bwino za kayendedwe ka madzi. Ngati aikidwa m'njira yolakwika, zimakhala ngati kuloza "njira yobwerera" kumayendedwe amadzi, ndipo madziwo amabwereranso. Panthawiyi, ingoyang'anani mosamala mivi yomwe ili pa valve ndikuyiyikanso m'njira yoyenera. Kuonjezera apo, malo oyika valavu ya cheke amafunikanso chidwi. Ngati itayikidwa pamphepete mwa payipi kapena pafupi ndi potulutsira madzi, kayendedwe ka madzi kamakhala kovuta ndipo mphamvu yake idzakhala yaikulu, zomwe zidzakhudza kugwira ntchito kwake. Iyenera kuyikidwa paipi yopingasa komanso yosasunthika yoyenda madzi, kutali ndi mapindikira ndi popopa, kuti ipange malo abwino ogwirira ntchito.

Kuwonongeka kwa chigawo chimodzi ndi chifukwa chofala. Mpando wa valve ndi ma valve ndi mbali zofunika kwambiri kuti mukwaniritse kusindikiza mu ma valve. Ngati valavu ya valavu yavala kwambiri ndipo sichingagwirizane bwino ndi mpando wa valve, madzi amadutsa pamtunda. Mofananamo, kusinthika kwa mpando wa valve kungakhudzenso kusindikiza. Pazovuta zotere, ngati kuchuluka kwa kuvala kapena kusinthika kuli kopepuka, zida zogaya zitha kugwiritsidwa ntchito pogaya bwino malo osindikizira kuti abwezeretse kusalala kwake ndi kusalala; Ngati kuwonongeka kuli kwakukulu, disiki yatsopano ya valve kapena mpando uyenera kusinthidwa. Kulephera kwa masika sikunganyalanyazidwe. Ili ndi udindo wokoka diski ya valve nthawi yake pamalo otsekedwa pamene madzi akusiya. Ngati masika kutopa, dzimbiri, ndi kutaya elasticity, valavu chimbale sangathe kutsekedwa mu nthawi. Panthawiyi, kasupe watsopano wokhala ndi zizindikiro zofanana ndi kasupe woyambirira ayenera kusinthidwa.

The sing'anga chinthu angayambitsenso kulephera kwachekeni valavu. Ngati madziwo ali ndi zonyansa zambiri monga matope, dzimbiri, ndi zina zotero, zonyansazi zidzakakamira pakati pa diski ya valve ndi mpando wa valve, kulepheretsa diski ya valve kutseka. Chosefera chikhoza kuikidwa kutsogolo kwa valve yowunikira, ndipo chophimba cha fyuluta chiyenera kutsukidwa nthawi zonse kuti muchepetse zonyansa zomwe zimalowa mu valve. Kuonjezera apo, kutentha ndi kupanikizika kwa madzi kungakhudzenso ntchito ya ma check valves. Ngati ipitilira kuchuluka kwake, njira zofananira ziyenera kuchitidwa, monga kuyika ma valve ochepetsa mphamvu kapena zida zozizirira.
