PVC Diaphragm Valve Txoj Cai thiab Fittings
PVC (polyvinyl chloride) thiab UPVC (unplasticized polyvinyl chloride) yog siv dav hauv kev tsim cov li qub thiab fittings vim lawv cov tshuaj tiv thaiv zoo heev thiab ua haujlwm ntev. Thaum nws los txog rau diaphragm li qub, cov ntsiab lus ntawm PVC diaphragm li qub ua lub luag haujlwm tseem ceeb hauv lawv txoj haujlwm.
Diaphragm li qub yog ib hom valve uas siv lub diaphragm hloov tau los tswj cov dej ntws. Lub hauv paus ntsiab lus tom qab PVC diaphragm li qub yog ua raws li kev txav ntawm lub diaphragm los tswj cov dej ntws. Thaum lub valve qhib, lub diaphragm yog nqa tawm, tso cai rau cov kua dej hla dhau. Hloov pauv, thaum lub valve raug kaw, lub diaphragm yog nias tawm tsam lub rooj zaum valve, tiv thaiv cov dej ntws.
Kev xaiv ntawm PVC lossis UPVC rau diaphragm valve fittings yog qhov tseem ceeb vim lawv cov tshuaj tsis haum thiab tsis muaj corrosive. Cov ntaub ntawv no zoo tagnrho rau kev tuav cov kua dej ntau, nrog rau cov kua qaub, alkalis, thiab lwm yam corrosive, ua rau lawv haum rau ntau yam kev siv.
Kev tsim ntawm PVC diaphragm li qub thiab fittings yog qhov tseem ceeb rau lawv txoj haujlwm zoo. Lub cev lub cev feem ntau yog ua los ntawm PVC lossis UPVC, muab lub tsev muaj zog thiab ruaj khov rau lub diaphragm thiab lwm yam khoom siv sab hauv. Lub diaphragm nws tus kheej yog ua los ntawm cov khoom siv hloov tau yooj yim, xws li roj hmab lossis cov thermoplastic elastomers, uas tso cai rau nws txav mus los thiab nqis los tswj cov dej ntws.
Kev siv PVC thiab UPVC nyob rau hauv diaphragm valve fittings xyuas kom meej tias cov li qub yog lub teeb yuag, yooj yim rau nruab, thiab yuav tsum tau saib xyuas tsawg. Tsis tas li ntawd, cov ntaub ntawv no tau txais txiaj ntsig zoo, ua rau lawv xaiv ntau yam kev lag luam, suav nrog kev kho dej, kev ua tshuaj, thiab kev tsim tshuaj.
Hauv kev xaus, cov hauv paus ntsiab lus ntawm PVC diaphragm li qub, ua ke nrog kev siv PVC thiab UPVC cov ntaub ntawv rau fittings, ua rau cov li qub no yog ib qho kev xaiv zoo heev rau kev tswj cov dej ntws hauv ntau hom kev lag luam. Lawv cov tshuaj tiv thaiv, ua haujlwm ntev, thiab tsim kom muaj txiaj ntsig ua rau lawv muaj kev txhim khu kev qha rau cov dej tuav cov kev xav tau.
