Chongani mavavu ndi magulu awo

Chongani valavu imatanthauza kuti gawo lomwe latsegulidwa ndi kutseka ndi disc yozungulira, yomwe imachita ndi kulemera kwake komanso kupanikizika pang'ono kuti muchepetse njira ya sing'anga. Ndi valavu yokha, yomwe imadziwikanso kuti cheke valavu, valavu imodzi, imabwezeretsa valavu kapena valavu. Makina oyenda oyenda amagawidwa kuti akweze mtundu wa mtundu ndi mtundu. Valavu yokweza ndiyofanana ndi zojambula zapadziko lonse lapansi, kupatula kuti zilibetsetsetsetse disc. Ma sing'anga amatuluka kuchokera ku doko la inles (mbali yotsika) ndikutuluka padoko lotuluka (kumtunda). Kukakamizidwa kwa itlet kuli kwakukulu kuposa kuchuluka kwa kuchuluka kwa disc ndi madzi ake kukana, valavu imatsegulidwa. Mosachedwa, valavu imatsekedwa pomwe sing'anga imayenda mmbuyo. Vesive Check Valive ali ndi disc yomwe imatha kuzungulira mozungulira axis, ndipo mfundo yake yogwira ntchito ndi yofanana ndi valavu yokweza. Valani valavu imagwiritsidwa ntchito ngati valavu yopumulira yopondaponda madzi. Kuphatikiza kwa valavu ya cheke ndi valavu imatha kusewera gawo la kudzipatula. Chongani mavalves ali m'gulu la ma valve a zokha, ndipo amagwiritsidwa ntchito makamaka pamapaipelines okhala ndi sing'anga imodzi, ndikungolola kuti sing'anga kuti muchepetse ngozi.

Matavala amagwiritsidwanso ntchito pamizere yomwe imapereka makina othandiza pomwe kupanikizika kumatha kuwonongeka kwa dongosolo. Chongani mavavu atha kukhala ogawika mavu a swing (kuzungulira malinga ndi likulu la mphamvu yokoka) ndikukweza mavamu (akuyenda motsatira axis).

Ntchito ya cheke cheke ndikungolola kuti sing'anga kuti mulowe mbali imodzi ndikuletsa kuyenda kwina. Nthawi zambiri nyama yamtunduwu imagwira ntchito zokha. Pansi pa ntchito yamadzimadzi ikuyenda mbali imodzi, valavu ya valavu imatsegulira; Mafuta akamayenda mbali inayo, Mpando wa Valve umangokhala ndi kupanikizika kwamadzi ndi kudzikuza kwa valavu yodula.

Chongani ma valves amaphatikiza ma valve a Swing Check ndi Maval Okweza. Vesive Check Vative ali ndi makina a Hinge, ndipo chitseko cha khomo ngati chimangodumphadumpha pampando. Kuti muwonetsetse kuti gulu la valavu imatha kufikira malo oyenera pampando nthawi iliyonse, Clack Clack idapangidwa mu chinyezi cha Hinge, kuti apangitse kuti akhale ndi zida zokwanira, ndipo amalumikizana ndi mpando wa Valve. Chipikacho chitha kupangidwa mwa chitsulo, kapena chitha kuvomerezedwa ndi zikopa, mphira, kapena chojambulachi pazitsulo, kutengera zofunikira za magwiridwe antchito. Vesive Cheveve Wosachedwa, kupanikizika kwamadzi komwe sikungachitike, kotero kukakamizidwa kumapangitsa valavu ndi yaying'ono. Valodi ya vundikiro yokweza imapezeka pampando wa valavu pa thupi la valavu. Kupatula kuti valavu imatha kugwa ndikugwa momasuka, valavu yonse ili ngati valavu yadziko lapansi. Kupanikizika kwamadzi kumapangitsa kuti khungu lisakweze pamwamba pa mpando wa valavu, ndipo msana wa sing'anga umapangitsa kuti valavu ibwerere ku mpando wa valavu ndikudula. Malinga ndi momwe mungagwiritsire ntchito, disc itha kukhala ya kapangidwe kazachitsulo konse, kapena mu mawonekedwe a bokosi la mphira kapena mphete ya mphira wokhazikika pa disc. Monga valavu yoyimilira, kudutsa kwa madzi otumphuka ndikuwunika bwino, kotero kukakamizidwa kutsika ndi valavu ya Swing Check ndiyabwino. osowa.
Gulu la Maval

Malinga ndi kapangidwe kake, mawonekedwe a cheke amatha kugawidwa mu valavu yokweza ma valve, Swing Tengani valavu ya valavu. Mitundu yolumikizira ya cheke iyi ikhoza kugawidwa m'mayinso anayi: kulumikizidwa kolumikizidwa, kulumikiza kwa kuyamwa, kulumikizana ndi kulumikizana ndi kugwirizanitsa kolumikizana ndi kulumikizana.

Malinga ndi zomwe zidachitikazo, valawa imagawidwa mu valavu ya valve, Brass Check Vative, Chepetsa chitsulo, kaboni pazisiyiro ndikusiyidwa.

Malinga ndi ntchito, valavu ya cheke imatha kulowa mu valavu ya Drvz chete, rvr chete cheke, sfcv bulve disvi ndi ddcv disc Check Vendve.
