Kodi valavu ya mpira wa PVC imatenga nthawi yayitali bwanji?

Mukuyika makina ndipo muyenera kudalira zida zake kwa zaka zambiri. Kungoyamba kung'amba ndikusintha ma valve omwe alephera nthawi zonse ndi vuto lalikulu komanso ndalama zomwe muyenera kupewa.

Valavu ya mpira ya PVC yopangidwa bwino imatha kukhala zaka 10 mpaka 20 mosavuta, kapena kupitirira apo m'malo abwino.

Zinthu Zomwe Zimakhudza Moyo wa Valve ya PVC

Ndi ma valve ati abwino a mkuwa kapena PVC?

Mukuona valavu yamkuwa ndi valavu ya PVC zili pambali. Kusiyana kwa mitengo ndi kwakukulu, koma ndi iti yomwe ili yabwino kwambiri pa ntchito yanu? Chisankho cholakwika chingakhale chokwera mtengo.

Palibe chilichonse mwa zinthuzi chomwe chili chabwino kuposa china chilichonse; chisankho chabwino kwambiri chimadalira momwe chingagwiritsidwire ntchito. PVC imagwira ntchito bwino m'malo owononga ndipo ndi yotsika mtengo. Mkuwa ndi wabwino kwambiri pa kutentha kwambiri, kupsinjika kwambiri, komanso zochitika zomwe zimafuna mphamvu zambiri.

Ili ndi limodzi mwa mafunso omwe gulu la Kapil Motwani limafunsa kawirikawiri. Yankho lake nthawi zambiri limapezeka pofunsa za fomu yofunsira.Ma PVCMphamvu yaikulu ndi kusakhala kwake ndi mankhwala. Sichikhudzidwa ndi dzimbiri konse. Pa makina okhala ndi madzi a m'chitsime, feteleza, madzi amchere, kapena ma asidi ofatsa, PVC imatha kupirira kwambiri kuposa mkuwa. Mkuwa ukhoza kuvutika ndi chinthu chotchedwakuchotsedwa kwa zinki, komwe madzi ena amachotsa zinc mu alloy, zomwe zimapangitsa kuti ikhale ndi mabowo komanso yofooka. PVC nayonso ndi yopepuka kwambiri komanso yotsika mtengo kwambiri. Komabe,mkuwandiye wopambana bwino pankhani ya kulimba. Imatha kupirira kutentha kwambiri ndi kupsinjika kuposa PVC, ndipo imapirira kwambiri kukhudzidwa ndi thupi. Ngati mukufuna valavu ya chingwe cha madzi otentha, chingwe cha mpweya wothamanga kwambiri, kapena pamalo omwe ingawonongeke, mkuwa ndiye chisankho chotetezeka. Pazinthu zambiri zogwiritsidwa ntchito m'madzi ozizira, PVC imapereka phindu labwino kwa nthawi yayitali.
