Momwe Ma Valves a Mpira Amagwiritsidwira Ntchito Zogwiritsa Ntchito M'madzi

Ma valve a mpiraamagwiritsidwa ntchito kwambiri m'machitidwe a m'madzi chifukwa cha kapangidwe kake kosavuta, kutseka mwamphamvu, komanso kugwira ntchito mwachangu. M'zombo, nthawi zambiri zimapezeka m'machitidwe a bilge, machitidwe a ballast, ndi mizere yotumizira mafuta, komwe kutseka kodalirika ndikofunikira.

Kuti zigwirizane ndi nyengo yovuta ya m'nyanja, ma valve a mpira wa m'nyanja amapangidwa ndi zinthu zosagwira dzimbiri monga mkuwa, bronze, kapena chitsulo chosapanga dzimbiri (316). Zipangizozi zimateteza ku dzimbiri la m'nyanja ndipo zimawonjezera nthawi yogwira ntchito. Zambiri zimakutidwa kapena kuphimbidwa ndi epoxy kapena nickel plating kuti zipereke chitetezo chowonjezera.

Chinthu china chofunikira kwambiri ndi kapangidwe kakang'ono. Malo ndi ochepa pa zombo, kotero ma valve a mpira wa m'madzi amapangidwa ndi kutalika kwa thupi kochepa pamene akusunga mphamvu zonse zoyendera. Kuphatikiza apo, mapangidwe oyandama kapena okhala ndi trunnion amatsimikizira kuti ntchito ikuyenda bwino ngakhale pansi pa kupanikizika kosinthasintha.

Poganizira za kukonza, kumasula mosavuta ndi mipando ndi zisindikizo zomwe zingathe kusinthidwa zimathandiza kukonza mwachangu panyanja. Kuphatikiza ndi kutsatira muyezo wa ISO kapena DIN, zinthuzi zimapangitsa mavavu a mpira wa m'madzi kukhala chisankho chodalirika kwa omanga zombo ndi ogwiritsa ntchito padziko lonse lapansi.
