PVC Standard Classification: Kunzwisisa Mhando Dzakasiyana dzePVC Valve Fittings

PVC, kana polyvinyl chloride, chinhu chinogoneka uye chinoshandiswa zvakanyanya mukugadzira zvigadzirwa zvakasiyana, kusanganisira mavharuvhu ekuisa. Kana zvasvika kune PVC valve fittings, zvakakosha kuti unzwisise iyo yakajairwa yemhando sisitimu inoshandiswa kuisa mumapoka emhando dzakasiyana dzekushongedza dziripo mumusika. Iyi yemhando system inobatsira vashandisi kuona chaiwo zvivakwa uye mashandisirwo ega ega ega PVC valve fitting, zvichiita kuti zvive nyore kusarudza yakakodzera kune imwe purojekiti kana application.

Iyo yakajairwa kupatsanurwa kwePVC valve fittings yakavakirwa pane akasiyana zvinhu, kusanganisira kuumbwa kwezvinhu, saizi, uye chinangwa chekushandiswa. Imwe yemhando dzakajairika dzePVC valve fittings inobva pamhando yezvinhu, iyo inosanganisira UPVC (unplasticized polyvinyl chloride) uye CPVC (chlorinated polyvinyl chloride). UPVC mavharuvhu mafittings anozivikanwa nekunaka kwawo kwemakemikari kuramba uye anowanzo shandiswa mumashandisirwo uko kushorwa kwekuora kwakakosha, senge zvidyarwa zvekuchenesa mvura, zvigadziriso zvemakemikari, uye masisitimu ekudiridza. Kune rumwe rutivi, CPVC valve fittings yakagadzirirwa kumira kutonhora kwepamusoro uye inowanzoshandiswa mumagadzirirwo emvura inopisa uye kushandiswa kwemaindasitiri.

Chimwe chinhu chakakosha cheiyo yakajairwa classification system yePVC valve fittings ndiyo saizi zviyero. PVC fittings inowanikwa muhukuru hwakasiyana, uye yakajairwa kupatsanura sisitimu inobatsira vashandisi kuona saizi chaiyo uye kuenderana nezvimwe zvikamu zvepombi. Yakajairwa saizi zviyero zvePVC valve fittings inosanganisira yezita pombi saizi (NPS) uye hurongwa, iyo inoratidza ukobvu hwemadziro ekukodzera.

Pamusoro pezvo, iyo yakajairwa dhizaini sisitimu inotarisawo kudzvanywa chiyero chePVC valve fittings. Kutsikirira ratings inoratidza iyo yakanyanya kudzvanywa iyo inokwana inogona kumira, uye iyo yakakosha pakuona kuchengetedzwa uye kuvimbika kwepombi system. PVC mavharuvhu mafittings anowanzo kuyererwa kune yakatarwa kudzvanywa mazinga, uye yakajairwa kupatsanurwa system inopa chiratidzo chakajeka chekudzvanywa kwemhando yega yega yekukodzera.

Mukupedzisa, iyo yakajairwa kupatsanurwa sisitimu yePVC mavharuvhu ekuisa inoita basa rakakosha mukubatsira vashandisi kunzwisisa zvivakwa, mashandisirwo, uye kuenderana kwemhando dzakasiyana dzemafirita. Kunyangwe iri UPVC kana CPVC, kunzwisisa iyo yakajairwa dhizaini sisitimu kwakakosha pakusarudza yakakodzera PVC vharafu inokodzera chimwe chirongwa kana application. Nekufunga zvinhu zvakaita serudzi rwezvinhu, saizi, uye chiyero chekumanikidza, vashandisi vanogona kuita sarudzo dzine ruzivo kana zvasvika pakusarudza PVC valve fittings kune avo pombi masisitimu.
