Valve ya mpira wa PVC

Vavu ya mpira wa PVC imapangidwa ndi vinyl chloride polima, yomwe ndi pulasitiki yogwira ntchito zambiri zamafakitale, malonda ndi nyumba. Valavu ya mpira wa PVC kwenikweni ndi chogwirira, cholumikizidwa ndi mpira woyikidwa mu valavu, kupereka magwiridwe antchito odalirika komanso kutsekedwa koyenera m'mafakitale osiyanasiyana.

Kupanga valavu ya mpira wa PVC

Mu mavavu a mpira wa PVC, mpirawo uli ndi dzenje lomwe madzi amatha kuyenda pamene mpirawo umagwirizana bwino ndi valavu. Mpira uli ndi dzenje, kapena doko, pakati, kotero kuti pamene doko likugwirizana ndi mapeto onse a valavu, madzi amatha kudutsa mu thupi la valve. Pamene valavu ya mpira yatsekedwa, dzenje limakhala lokhazikika kumapeto kwa valve ndipo palibe madzi omwe amaloledwa kudutsa. Chogwirizira paValve ya mpira wa PVCnthawi zambiri ndi yosavuta kupeza ndi kugwiritsa ntchito. Chogwiririra chimapereka ulamuliro wa malo a valve. PVC mavavu mpira ntchito mapaipi, mapaipi, mankhwala madzi oipa ndi mafakitale ena. Kwenikweni, bizinesi iliyonse imagwiritsa ntchito mapaipi kunyamula gasi, zamadzimadzi komanso zolimba zoyimitsidwa.Ma valve a mpiraimathanso kukhala yosiyana kukula, kuchokera ku mavavu ang'onoang'ono a mpira mpaka ma valve awiri a phazi.

PVC ili ndi kukana kwambiri kwamadzi, kukana kwa mankhwala komanso kukana kwamphamvu kwa asidi. Chifukwa chodalirika komanso kulimba, PVC ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, malonda ndi nyumba.

Kugwiritsa ntchito mapulasitiki a PVC

Pulasitiki ya PVC nthawi zambiri imagwiritsidwa ntchito popanga mapaipi, ma ID, malaya amvula ndi matailosi apansi. Chifukwa cha izi, ma valve a mpira a PVC amapereka ntchito zokhazikika, zodalirika komanso moyo wautali wazinthu, zomwe zimawapangitsa kukhala okwera mtengo kwambiri.
