Ntchito yanga yaposachedwa kwambiri inali yodziwa kuti valavu ya mpira iti yomwe iyenera kugwiritsidwa ntchito m'malo mwa valavu yakale ya mpira m'nkhokwe. Nditayang'ana pazosankha zosiyanasiyana zakuthupi ndikudziwa kuti zitha kulumikizana ndi chitoliro cha PVC, mosakayikira ndimayang'ana aValve ya mpira wa PVC.

Pali mitundu itatu yosiyana ya mavavu a mpira a PVC, iliyonse ili ndi ubwino wake. Mitundu itatuyi ndi yaying'ono, yophatikizidwa ndi CPVC. Mu blog iyi, tiwona zomwe zimapangitsa mtundu uliwonse wamtunduwu kukhala wapadera komanso mapindu omwe aliyense ali nawo.

Valve ya Mpira wa PVC Yophatikizika
Valavu yampira ya PVC yophatikizika imapangidwa pogwiritsa ntchito njira ya nkhungu yofotokozedwa mu blog yathu Njira Zomangamanga. Kugwiritsa ntchito njira yapaderayi yopangira pulasitiki kuzungulira mpira ndi tsinde kumapereka mapindu angapo. Mpira wathunthu umagwiritsidwa ntchito, koma palibe msoko mu valavu chifukwa uyenera kuwonjezeredwa kuchokera kumapeto. Izi zimapangitsa valavu kukhala yolimba komanso yophatikizika popanda kulepheretsa kuyenda. Vavu ya mpira ya PVC yophatikizika imapezeka mu IPS (Kukula kwa Chitoliro cha Iron) ndi zolumikizira zolumikizira za Pulogalamu 40 ndi chitoliro cha 80.

Monga valavu yolimba komanso yolimba, ndi yabwino kwa mitundu yosiyanasiyana ya madzi. Mukafuna valavu yachuma, valavu ya mpira ya PVC yophatikizika ndi yabwino kwambiri.

Alliance PVC Ball Valve
Mapangidwe a Union amaphatikizira mgwirizano pa cholumikizira chimodzi kapena zonse ziwiri kuti alole kukonzanso kwapaintaneti kwa valavu popanda kuyichotsa papaipi. Palibe zida zapadera zokonzekera zomwe zimafunikira, chifukwa chogwiriracho chili ndi zingwe ziwiri zazikulu zomwe zimalola chogwiriracho kuti chigwiritsidwe ntchito ngati wrench yosinthika. Pamene kukonza ma valve kumafunika, mphete yosungiramo ulusi ikhoza kusinthidwa kapena kuchotsedwa pogwiritsa ntchito chogwirira kuti chisindikize chisindikizo kapena m'malo mwa O-ring.

Dongosolo likamapanikizika, mgwirizano ukangotha, mgwirizano wotsekedwa udzalepheretsa mpirawo kukankhidwira kunja, ndipo mgwirizano wa zachuma sudzakhala ndi chilichonse choletsa mpirawo kukankhidwira kunja.

Kodi mumadziwa? Mavavu ophatikizika ndi ophatikizika a PVC a mpira akupezeka pamakina a Ndandanda 40 ndi Schedule 80 popeza mavotiwa amatanthawuza makulidwe a khoma la chitoliro.PVC valavu mpiraamavoteredwa pa kukakamizidwa osati makulidwe a khoma, kuwalola kukhala oyenera Ndandanda 40 ndi Ndandanda 80 mapaipi. Kuzungulira kwakunja kwa machubu awiri kumakhalabe komweko, ndipo m'mimba mwake m'kati mwake umachepa pamene makulidwe a khoma akuwonjezeka. Nthawi zambiri, chitoliro cha 40 ndi choyera ndipo chitoliro cha 80 ndi chotuwa, koma valavu yamtundu uliwonse ingagwiritsidwe ntchito panjira iliyonse.

CPVC valavu ya mpira
Ma valve a mpira a CPVC (chlorinated polyvinyl chloride) amapangidwa mofanana ndi ma valve ophatikizana, omwe ali ndi kusiyana kwakukulu kuwiri; mawerengero a kutentha ndi kugwirizana.Mavavu a mpira a CPVCamapangidwa kuchokera ku PVC ya chlorine, yomwe imawathandiza kupirira kutentha kwambiri. Ma valve awa adapangidwa kuti azipaka madzi otentha mpaka 180 ° F.

Kulumikizana kwa valavu ya mpira wa CPVC ndi CTS (kukula kwa chubu chamkuwa), komwe kumakhala ndi kukula kwapaipi kakang'ono kwambiri kuposa IPS. CTS idapangidwira machitidwe amadzi otentha ndi ozizira, ngakhale kuti amagwiritsidwa ntchito makamaka pamizere yamadzi otentha.

Mavavu a mpira a CPVC ali ndi mtundu wa beige kuti athandize kuwasiyanitsa ndi mavavu a mpira ozungulira oyera. Ma valve awa ali ndi kutentha kwakukulu ndipo ndi abwino kwa ntchito zotenthetsera monga zotenthetsera madzi.

Mavavu a mpira wa PVC ndi njira yabwino kwambiri yopangira ma plumbing osiyanasiyana, ndikukonza kosiyanasiyana komanso kutentha kwakukulu. Ma valve a mpira amapezekanso mkuwa ndi zitsulo zosapanga dzimbiri, kotero pali valavu ya mpira pa ntchito iliyonse yomwe imayenera kuyendetsa madzi.
