Mfundo zofunika kuziganizira

Mfundo yogwirira ntchito ndi ntchito ya valve yothandizira

1, valavu yopumira nthawi zonse imasefukira: mu kachulukidwe kapope kachulukidwe kachitidwe, pampu yochulukira imapereka kuyenda kosalekeza. Pamene kupanikizika kwa dongosolo kumawonjezeka, kufunikira kothamanga kudzachepa. Panthawiyi, valve yothandizira imatsegulidwa, kotero kuti kutuluka kwakukulu kumabwereranso ku thanki, kuonetsetsa kuti mpweya wotsekemera wa valve, ndiko kuti, kuthamanga kwa mpweya wa pampu kumakhala kosalekeza (doko la valve nthawi zambiri limatsegulidwa ndi kusinthasintha kwa kuthamanga) .

2, chitetezo cha chitetezo: Pamene dongosolo likugwira ntchito bwino, valve imatsekedwa. Pokhapokha pamene katunduyo adutsa malire omwe atchulidwa (kupanikizika kwa dongosolo kumadutsa kupanikizika kokhazikitsidwa), kusefukira kumatsegulidwa kuti atetezedwe mochulukira, kotero kuti kupanikizika kwa dongosolo sikulinso kuwonjezeka (kawirikawiri kupanikizika kwa valve yothandizira ndi 10% mpaka 20% apamwamba kuposa kupanikizika kwakukulu kwa ntchito ya dongosolo).

3, ngati valavu yotsitsa yomwe imagwiritsidwa ntchito ngati chowongolera chakutali:

Valve yapamwamba komanso yotsika kwambiri yowongolera ma multistage imagwiritsidwa ntchito ngati valavu yotsatizana kuti ipangitse kukakamiza kumbuyo (chingwe pamayendedwe obwerera mafuta).

Valavu yothandizira woyendetsa ili ndi magawo awiri: valavu yayikulu ndi valavu yoyendetsa. Mavavu oyendetsa ndege amafanana ndi ma valve oyendetsa mwachindunji, koma nthawi zambiri amakhala mipando yokhala ngati ma cone (kapena valavu ya mpira). Valavu yayikulu imatha kugawidwa m'magulu amodzi, awiri okhazikika komanso atatu okhazikika.

Pa valve yaikulu, pali kusiyana koonekeratu kuchokera ku ma valve ena othandizira. Valavu yayikulu yothandizira chofufutira ndi ntchito yolimbikitsa idzakhala ndi chitoliro chopitilira chimodzi. Vuto la valavu yayikulu yoperekera chithandizo nthawi zambiri ndikuti kasupe wamkati wathyoka kapena kulephera, nsonga ya valve yavala, ndipo ntchito yonseyo ndi yofooka ndipo kupanikizika sikungakhazikitsidwe.
