Kodi pali kusiyana kotani pakati pa valavu ya mpira yoyandama ndi yokhazikika

Mtundu woyandama ndi mtundu wokhazikika wa valavu ya mpira umasiyana kwambiri ndi mawonekedwe, mfundo zogwirira ntchito komanso kugwiritsa ntchito ntchito.

1. Maonekedwe

1. Vavu yoyandama ya mpira ndi valavu yokhazikika ya mpira imakhala yosavuta kusiyanitsa mawonekedwe.Ngati thupi la valavu lili ndi shaft yotsika yokhazikika, iyenera kukhala valavu yokhazikika.
2. Ngati pali valavu yamafuta pampando wa valavu ya mpira, ndiye valavu yokhazikika ya mpira.Koma osati mwanjira ina, sikuli koyenera kukhala ndi valavu yoyandama popanda valavu yokhala ndi mafuta, chifukwa kukula kochepa monga 1 "300LB valve yokhazikika ya mpira nthawi zambiri ilibe valavu yokhala ndi mafuta.

2. Mfundo yogwira ntchito

1. Mpira wa valavu yoyandama imakhala ndi tsinde lapamwamba lokha, ndipo mpirawo ukhoza kusamutsidwa pang'ono, choncho umatchedwa valavu yoyandama.Palinso shaft yokhazikika pansi pa valve yokhazikika ya mpira, yomwe imakonza malo a mpirawo, choncho sungathe kuchotsedwa, choncho imatchedwa valve yokhazikika.
2. Mpira wa valve yoyandama umasunthidwa chifukwa cha kupanikizika kwapakati, ndipo umamangirizidwa mwamphamvu ku mpando wa valve kuti ukwaniritse kusindikiza.Ndikoyenera kuganizira ngati zinthu za mpando wa valve zingathe kupirira kupanikizika kwa ntchito.Chigawo cha valve yokhazikika ya mpira chimakhazikitsidwa, ndipo mpando wa valve umasunthidwa ndi kukakamizidwa kwa sing'anga, ndipo umamangirizidwa mwamphamvu ku gawolo kuti akwaniritse kusindikiza.

3. Ntchito ndi ntchito

1. Vavu yoyandama ya mpira ndi yoyenera kupanikizika kwapakatikati ndi kochepa, ndipo m'mimba mwake ndi yaying'ono;valve yokhazikika imatha kupirira mpaka 2500LB, ndipo kukula kwake kumatha kufika mainchesi 60.Mwachitsanzo, valavu yayikulu kwambiri komanso yothamanga kwambiri ya VTON ku United States imagwiritsa ntchito valve yokhazikika ya mpira.
2. Vavu yokhazikika ya mpira imatha kuzindikira ntchito ya kukana kawiri ndi mizere iwiri, pomwe valavu yoyandama imakhala yosindikizira njira imodzi.Valavu yokhazikika ya mpira imatha kutsekereza sing'anga pamapeto onse a kumtunda ndi kumunsi kwamtsinje nthawi yomweyo.Pamene kupsyinjika kwa mphuno ya thupi la valve kuli kwakukulu kuposa mphamvu yomangirira ya kasupe wa mpando wa valve, mpando wa valve udzakankhidwa kuti utulutse kupanikizika muzitsulo, ndipo phukusi liri lotetezeka.
3. Mavavu a mpira okhazikika nthawi zambiri amakhala ndi moyo wautali kuposa ma valve oyandama.
4. Mphamvu ya valve yokhazikika ya mpira ndi yaying'ono kusiyana ndi ya valve yoyandama ya mpira, choncho ntchitoyo ndi yopulumutsa ntchito.
5. Valovu yokhazikika pamwamba pa mainchesi 4 ili ndi valavu ya jekeseni ya mafuta, koma valavu ya mpira woyandama sichitha.
6. Kusindikiza kwa valve yokhazikika ndi yodalirika kwambiri: mphete ya PTFE imodzi yosindikizira yamtengo wapatali imayikidwa mu mpando wa valve zitsulo zosapanga dzimbiri, ndipo mapeto a mchira wa mpando wa valve wachitsulo amaperekedwa ndi kasupe kuti atsimikizire mphamvu yokwanira yolimba. wa mphete yosindikizira.Valve ikupitiriza kuonetsetsa kuti ntchito yabwino yosindikiza ikugwira ntchito pansi pa kasupe.
