Mfundo yogwira ntchito ya valve yotulutsa mpweya
Nthawi zambiri ndimamva tikulankhula za mavavu osiyanasiyana. Lero, nditidziwitsa za mfundo yogwirira ntchito ya valve yotulutsa mpweya.
Pamene mpweya uli m'dongosolo, mpweya umachulukana kumtunda wa valve yotulutsa mpweya, mpweya umachulukana mu valve, ndipo kuthamanga kumakwera. Kuthamanga kwa gasi kukakhala kwakukulu kuposa kuthamanga kwa dongosolo, mpweya udzagwetsa mulingo wamadzi m'chipindamo, ndipo choyandamacho chidzatsika ndi madzi. Yatsani utsi Mukatha gasi, mlingo wa madzi umakwera, ndipo kuyandama kumakwera moyenerera. Kuti mutseke khomo lotulutsa mpweya, monga kulimbitsa kapu ya valve pa thupi la valve, valve yotulutsa mpweya imasiya kutopa. Kawirikawiri, kapu ya valve iyenera kukhala pamalo otseguka, ndipo imathanso kulumikizidwa ndi Valavu yodzipatula imagwiritsidwa ntchito pamodzi kuti athandize kukonza valavu yotulutsa mpweya.
1. Kuyandama kwa valve yotulutsa mpweya kumapangidwa ndi PPR yochepa kwambiri ndi zipangizo zophatikizika, zomwe sizidzasokoneza ngakhale zitamizidwa m'madzi otentha kwa nthawi yaitali. Sizidzabweretsa zovuta pakuyenda kwa pontoon.
2. Chombo cha buoy chimapangidwa ndi pulasitiki yolimba, ndipo kugwirizana pakati pa lever ndi buoy ndi kuthandizira kumatenga kugwirizana kosunthika, kotero sikudzakhala ndi dzimbiri panthawi yogwira ntchito kwa nthawi yayitali ndikupangitsa kuti dongosololi lisagwire ntchito ndikuyambitsa madzi.
3. Chisindikizo chakumapeto kwa lever chimathandizidwa ndi kasupe wovuta, womwe ukhoza kukhala wosakanikirana ndi kayendetsedwe ka lever kuti zitsimikizire kuti kusindikiza kumagwira ntchito popanda kutha.
4. Pamene valve yotulutsa mpweya imayikidwa, ndi bwino kuyiyika pamodzi ndi valve yotsekera, kotero kuti pamene valve yotulutsa mpweya iyenera kuchotsedwa kuti ikonzedwe, dongosololi likhoza kusindikizidwa ndipo madzi sangatuluke. Zinthu zotsika kwambiri za PP, izi sizidzapunthwa ngakhale zitamizidwa m'madzi otentha kwa nthawi yayitali.
