Kuyamba kwa PVC Ball Valves

Zomwe zimagwiritsidwa ntchito poyang'ana malo, ma valve a mpira a PVC amakulolani kuti mutsegule ndi kuzimitsa kutuluka kwa zakumwa mwamsanga, pamene mukupanga chisindikizo chopanda madzi.Ma valves awa amagwira ntchito bwino pamadziwe, ma laboratories, mafakitale a zakudya ndi zakumwa, mankhwala a madzi, ntchito za sayansi ya moyo ndi ntchito za mankhwala.Mavavuwa ali ndi mpira mkati mwake womwe umazungulira pamadigiri 90.Bowo lodutsa pakati pa mpira limalola madzi kuyenda momasuka pamene valavu ili pa "pa" malo, ndikuyimitsa kutuluka kwathunthu pamene valavu ili "pa" malo.

Mavavu a mpira amatha kupangidwa kuchokera kuzinthu zosiyanasiyana, koma PVC ndiyomwe imasankhidwa nthawi zambiri.Chomwe chimapangitsa izi kukhala zotchuka kwambiri ndikukhalitsa kwawo.Zomwe zili ndi dzimbiri sizikhala ndi dzimbiri komanso sizisamalidwa bwino, kotero zimatha kugwiritsidwa ntchito panja pomwe sizikufunika nthawi zambiri, koma zikafunika ndizofunikira kuti zizigwira ntchito moyenera.Atha kugwiritsidwanso ntchito posakaniza mankhwala, pomwe dzimbiri lingakhale vuto lalikulu.Kuthamanga kwamphamvu kwa PVC kumapangitsanso kuti ikhale yotchuka kwa ntchito zomwe madzi amayenda pamagetsi.Vavu ikatsegulidwa, kutsika kwapang'onopang'ono kumakhala kochepa chifukwa doko la mpirawo limakhala lofanana kukula kwa doko la chitoliro.

Mavavu a mpira a PVC amabwera mumitundu yosiyanasiyana.Timanyamula mavavu kuyambira 1/2 inchi mpaka 6 mainchesi, koma zosankha zazikulu zitha kupezeka ngati pakufunika.Timanyamula mgwirizano weniweni, mgwirizano weniweni ndi ma valve opangidwa ndi mpira kuti tikwaniritse zosowa zosiyanasiyana.Ma valve ogwirizana enieni ndi otchuka kwambiri chifukwa amalola kuchotsa gawo la chonyamulira cha valve, popanda kuchotsa valavu yonse kunja kwa dongosolo, kotero kukonzanso ndi kukonza kumakhala kosavuta.Zonse zimakhala ndi kulimba kwa PVC kuti zikupatseni zaka zambiri zogwiritsa ntchito.
