Mafotokozedwe Akatundu
Valavu yoyang'ana chete imapangidwa ndi thupi la valve, mpando wa valve, kalozera wamayendedwe, ma disc a valve, masika ndi zina.Njira yolowera mkati imatengera kapangidwe kamene kamakhala ndi kutayika kochepa.Kutsegula ndi kutseka kwa disc valve ndi kochepa kwambiri.Ikhoza kutsekedwa mwamsanga pamene pampu yayimitsidwa, kuteteza nyundo yaikulu ya madzi ndikupangitsa kuti phokoso likhale lopanda phokoso.Vavu iyi imagwiritsidwa ntchito makamaka popereka madzi, ngalande, chitetezo chamoto, ndi machitidwe a HVAC.Ikhoza kukhazikitsidwa potuluka pampopi yamadzi kuti muteteze kubweza kwapakati komanso kuwonongeka kwa nyundo yamadzi pampopi.
Zogulitsa Zamankhwala
1. Njira yamkati yamkati ya valve yotsekera mwakachetechete imatenga kamangidwe kamene kamakhala kosavuta, kamene kamakhala ndi kukana kwazing'ono komanso kupulumutsa mphamvu.Imatsekedwa ndi mphamvu yake ya kasupe kuti iteteze nyundo yamadzi.
2. Pamene mpope imayimitsidwa, diski ya valve imakhala ndi nthawi yochepa yotseka ndi akasupe angapo ndipo ikhoza kutsekedwa mwamsanga kuti ipewe nyundo ya madzi ndi phokoso lalikulu la nyundo yamadzi, ndikupanga zotsatira zopanda pake.
3. Valavu iyi iyenera kukhazikitsidwa molunjika (mzere wa thupi la valve ndi wowongoka).
