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

PVC (polyvinyl chloride) thiab UPVC (unplasticized polyvinyl chloride) yog cov khoom siv dav siv hauv kev tsim cov khoom siv valve. Cov ntaub ntawv yas no paub txog lawv cov kav ntev, kev tiv thaiv corrosion, thiab pheej yig, ua rau lawv muaj kev xaiv nrov rau ntau yam kev siv, nrog rau cov kav dej, dej, thiab kev lag luam.

Ib hom valve haum ua los ntawm PVC lossis UPVC yog PVC hauv qab valve, uas yog tsim los tswj cov dej ntws thiab tiv thaiv rov qab. Lub hauv paus ntsiab lus ua haujlwm ntawm PVC hauv qab valve yog ua raws li qhov yooj yim tab sis siv tau zoo. Thaum cov kua dej ntws mus rau qhov xav tau, lub valve qhib kom tso cai rau cov dej nkag mus. Txawm li cas los xij, thaum muaj kev thim rov qab hauv qhov ntws, lub valve tau kaw cia kom tsis txhob rov qab los ntawm cov kua dej.

Cov khoom tseem ceeb ntawm PVC hauv qab valve suav nrog lub cev lub cev, uas feem ntau yog ua los ntawm PVC lossis UPVC, thiab cov txheej txheem sib khi xws li roj hmab lossis silicone gasket. Thaum cov kua dej siab siab dua nyob rau sab inlet ntawm lub valve, nws thawb tawm tsam lub sealing mechanism, ua rau lub valve qhib thiab tso cai rau cov kua nkag mus. Piv txwv li, thaum lub siab ntawm lub qhov hluav taws xob sab yuav siab dua, lub sealing mechanism yog nias tawm tsam lub rooj zaum valve, zoo sealing tawm ntawm qhov txaus.

Kev siv PVC los yog UPVC hauv kev tsim kho hauv qab 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. Tsis tas li ntawd, PVC thiab UPVC yog resistant rau corrosion, tshuaj degradation, thiab kev loj hlob ntawm lom, ua rau lawv haum rau siv nyob rau hauv ib tug ntau yam ntawm ib puag ncig, nrog rau corrosive thiab abrasive tej yam kev mob.

Tsis tas li ntawd, PVC thiab UPVC hauv qab li qub yog cov txiaj ntsig zoo rau cov khoom siv hlau qub, muab kev sib piv ntawm tus nqi qis. Lawv cov npoo sab hauv du kuj txo qis kev poob siab thiab turbulence, pab ua kom cov kua dej txaus.

Hauv kev xaus, PVC thiab UPVC yog ntau yam khoom siv rau kev tsim cov khoom siv valve, suav nrog hauv qab li qub. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm PVC hauv qab valve yog ua raws li cov txheej txheem txhim khu kev qha ntawm cov kua dej kom tswj tau qhov ntws thiab tiv thaiv rov qab. Nrog rau lawv cov durability, corrosion kuj, thiab nqi-zoo, PVC thiab UPVC hauv qab li qub yog cov khoom tseem ceeb hauv ntau lub tshuab tswj dej.
