PVC (polyvinyl chloride) thiab UPVC (unplasticized polyvinyl chloride) yog cov khoom siv dav siv hauv kev tsim khoom ntawm ntau yam valve fittings.

Cov ntaub ntawv no paub txog lawv cov kav ntev, tiv thaiv corrosion, thiab pheej yig, ua rau lawv nyiam xaiv rau ntau yam kev siv. Ib hom valve haum uas feem ntau ua los ntawm PVC lossis UPVC yog npauj npaim valve.

Lub hauv paus ntsiab lus ntawm PVC npauj npaim valve yog ua raws li kev tsim qauv yooj yim thiab siv tau zoo. Lub valve muaj ib tug disc, uas yog mounted rau ib tug rotating ncej. Thaum lub valve nyob rau hauv txoj hauj lwm kaw, lub disc yog perpendicular rau cov dej ntws, zoo thaiv nws. Thaum lub valve qhib, lub disc tig mus rau qhov sib npaug ntawm qhov ntws, tso cai rau cov kua dej dhau los.

Kev siv PVC lossis UPVC hauv kev tsim cov npauj npaim li qub muaj ntau yam zoo. Cov ntaub ntawv no yog lub teeb yuag, ua rau cov li qub yooj yim los tuav thiab nruab. Lawv kuj tiv taus corrosion, ua rau lawv haum rau siv nyob rau hauv ntau qhov chaw, nrog rau cov uas raug cov tshuaj los yog hnyav huab cua puag. Tsis tas li ntawd, PVC thiab UPVC tsis muaj tshuaj lom thiab muaj kev nyab xeeb rau kev siv hauv cov ntawv thov uas muaj dej haus lossis ua zaub mov.

Lub sab hauv du ntawm PVC thiab UPVC npauj npaim li qub txo qis kev ua haujlwm tsis zoo, txo qis kev poob siab thiab kev siv zog. Qhov no ua rau lawv muaj kev xaiv zoo rau kev tswj cov dej ntws hauv lub cev. Tsis tas li ntawd, cov ntaub ntawv no muaj kev saib xyuas tsawg, yuav tsum tau saib xyuas tsawg kawg ntawm lawv lub neej.

PVC thiab UPVC npauj npaim li qub feem ntau siv rau hauv kev lag luam xws li kev kho dej, dej, kev ua tshuaj, thiab HVAC systems. Lawv versatility thiab nqi-zoo ua rau lawv ib tug nrov xaiv rau kev tswj cov dej ntws, huab cua, thiab lwm yam kua nyob rau hauv ib tug ntau yam ntawm kev siv.

Hauv kev xaus, lub hauv paus ntsiab lus ntawm PVC npauj npaim valve yog raws li kev sib hloov ntawm lub disc los tswj cov dej ntws. Kev siv cov khoom siv PVC thiab UPVC hauv kev tsim kho cov li qub no muaj ntau yam txiaj ntsig, suav nrog kev ua haujlwm ntev, kev tiv thaiv corrosion, thiab kev ua haujlwm zoo. Cov kev ua tau zoo no ua rau PVC thiab UPVC npauj npaim li qub yog ib qho kev txhim khu kev qha thiab raug nqi zoo rau kev tswj dej hauv ntau qhov chaw lag luam thiab kev lag luam.
