Valavu ya mpira wa PVC

Valavu ya mpira wa PVC imapangidwa ndi vinyl chloride polymer, yomwe ndi pulasitiki yogwira ntchito zambiri m'makampani, m'malonda ndi m'nyumba. Valavu ya mpira wa PVC kwenikweni ndi chogwirira, cholumikizidwa ku mpira womwe umayikidwa mu valavu, zomwe zimapangitsa kuti ntchito ikhale yodalirika komanso yotseka bwino m'mafakitale osiyanasiyana.

Kapangidwe ka valavu ya mpira wa PVC

Mu ma valve a mpira a PVC, mpira uli ndi dzenje lomwe madzi amatha kudutsamo ngati mpirawo walumikizidwa bwino ndi valavu. Mpirawo uli ndi dzenje, kapena doko, pakati, kotero kuti doko likalumikizidwa ndi malekezero onse awiri a valavu, madzi amatha kuyenda kudzera m'thupi la valavu. Vavu ya mpira ikatsekedwa, dzenjelo limakhala lolunjika kumapeto kwa valavu ndipo palibe madzi omwe amaloledwa kudutsa. Chogwirira paValavu ya mpira wa PVCKawirikawiri zimakhala zosavuta kupeza ndi kugwiritsa ntchito. Chogwiriracho chimapereka ulamuliro pa malo a valavu. Ma valavu a mpira wa PVC amagwiritsidwa ntchito m'mapaipi, mapaipi, kuyeretsa madzi otayidwa ndi mafakitale ena. Mwachidule, makampani onse amagwiritsa ntchito mapaipi kunyamula gasi, madzi ndi zinthu zolimba zomwe zimapachikidwa.Ma valve a mpiraZingasiyanenso kukula, kuyambira ma valavu ang'onoang'ono a mpira mpaka ma valavu a m'mimba mwake wa phazi.

Ma valve a mpira wa PVC amapangidwa ndi membala wa banja la vinyl resin. PVC imayimira polyvinyl chloride, yomwe ndi thermoplastic polymer material, zomwe zikutanthauza kuti imasintha mawonekedwe ake akatenthedwa kapena kuzizira. Ma thermoplastic, monga PVC, ndi abwino kwa chilengedwe chifukwa amatha kusungunuka ndikusintha mawonekedwe ake nthawi zambiri, zomwe zikutanthauza kuti sadzaza malo otayira zinyalala. PVC ili ndi kukana bwino madzi, kukana mankhwala komanso kukana asidi kwambiri. Chifukwa cha kudalirika kwake komanso kulimba kwake, PVC ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, mabizinesi komanso nyumba.

Kugwiritsa ntchito mapulasitiki a PVC

Pulasitiki ya PVC nthawi zambiri imagwiritsidwa ntchito popanga mapaipi, makadi ozindikiritsa, ma coat a mvula ndi matailosi apansi. Chifukwa cha izi, ma valve a mpira wa PVC amapereka magwiridwe antchito okhazikika komanso odalirika komanso moyo wautali wazinthu, zomwe zimapangitsa kuti azigwiritsidwa ntchito motsika mtengo kwambiri. Kuphatikiza apo, ma valve a mpira wa PVC ndi osavuta kuyeretsa ndi kusamalira.
