PVC Standard Classification: Nkag siab txog qhov sib txawv ntawm PVC Valve Fittings

PVC, lossis polyvinyl chloride, yog cov khoom siv ntau yam thiab siv dav hauv kev tsim khoom ntawm ntau yam khoom, nrog rau cov khoom siv valve. Thaum nws los txog rau PVC valve fittings, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem kev faib tawm uas siv los txheeb xyuas ntau hom fittings muaj nyob hauv khw. Qhov kev faib tawm no pab cov neeg siv txheeb xyuas cov khoom tshwj xeeb thiab kev siv ntawm txhua hom PVC valve haum, ua kom yooj yim rau xaiv qhov haum rau ib qhov project lossis daim ntawv thov.

Cov txheej txheem kev faib tawm ntawm PVC valve fittings yog nyob ntawm ntau yam, nrog rau cov khoom muaj pes tsawg leeg, qhov loj me, thiab kev npaj siv. Ib qho kev faib tawm ntau tshaj plaws rau PVC valve fittings yog raws li cov khoom siv, uas suav nrog UPVC (unplasticized polyvinyl chloride) thiab CPVC (chlorinated polyvinyl chloride). UPVC valve fittings paub txog lawv cov tshuaj tiv thaiv zoo heev thiab feem ntau siv rau hauv cov ntawv thov uas muaj kev tiv thaiv corrosion yog qhov tseem ceeb, xws li cov chaw kho dej, cov chaw ua tshuaj, thiab cov kav dej. Ntawm qhov tod tes, CPVC valve fittings yog tsim los tiv taus qhov kub thiab txias thiab feem ntau siv rau hauv cov dej kub faib tshuab thiab cov ntawv thov kev lag luam.

Lwm qhov tseem ceeb ntawm cov txheej txheem kev faib tawm rau PVC valve fittings yog cov qauv sizing. PVC fittings muaj nyob rau hauv ntau qhov ntau thiab tsawg, thiab cov txheej txheem kev faib tawm pab cov neeg siv txheeb xyuas qhov loj thiab sib haum nrog lwm cov kav dej. Cov qauv sizing ntau rau PVC valve fittings suav nrog cov yeeb nkab nominal loj (NPS) thiab lub sijhawm, uas qhia txog phab ntsa tuab ntawm qhov haum.

Tsis tas li ntawd, cov txheej txheem kev faib tawm kuj suav nrog kev ntsuas siab ntawm PVC valve fittings. Kev ntsuas siab qhia qhov siab tshaj plaws uas qhov haum tuaj yeem tiv taus, thiab lawv yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kav dej. PVC valve fittings feem ntau yog ntsuas rau qhov tshwj xeeb siab ntau yam, thiab cov txheej txheem kev faib tawm muab qhov qhia meej ntawm qhov ntsuas siab rau txhua hom kev haum.

Hauv kev xaus, cov txheej txheem kev faib tawm rau PVC valve fittings plays lub luag haujlwm tseem ceeb hauv kev pab cov neeg siv nkag siab txog cov khoom, kev siv, thiab kev sib raug zoo ntawm ntau hom fittings. Txawm hais tias nws yog UPVC lossis CPVC, kev nkag siab txog cov txheej txheem kev faib tawm yog qhov tseem ceeb rau kev xaiv txoj cai PVC valve haum rau ib qhov project lossis daim ntawv thov. Los ntawm kev xav txog yam xws li cov khoom siv, qhov loj me, thiab kev ntsuas siab, cov neeg siv tuaj yeem txiav txim siab paub thaum nws los xaiv PVC valve fittings rau lawv cov kav dej.
