I-PVC (i-polyvinyl chloride) ne-UPVC (i-polyvinyl chloride engafakwanga ipulasitiki) yizinto ezisetshenziswa kakhulu ekwenzeni ama-valve ahlukahlukene.

I-PVC (i-polyvinyl chloride) ne-UPVC (i-polyvinyl chloride engafakwanga ipulasitiki) yizinto ezisetshenziswa kakhulu ekwenzeni ama-valve ahlukahlukene. Lezi zinto ziyaziwa ngokuqina kwazo, ukumelana nokugqwala, kanye nokuthengeka kwazo, okuzenza zibe ukukhetha okudumile ezinhlobonhlobo zezinhlelo zokusebenza. Enye yezinto ezivame ukusetshenziswa kakhulu zokufakwa kwamavalvu ezenziwe nge-PVC ne-UPVC ivalve uvemvane.

Umgomo wokusebenza we-valve uvemvane lwe-PVC usekelwe ekwakhiweni okulula kodwa okuphumelelayo. Lolu hlobo lwevalvu luqukethe idiski, eyaziwa nangokuthi "uvemvane," ebekwe phakathi nendawo yepayipi. I-disc ixhunywe ku-rod noma ku-shaft efinyelela ngaphandle kwe-valve, okuvumela ukusebenza okwenziwa ngesandla noma okuzenzakalelayo.

Lapho i-valve isendaweni evaliwe, i-disc i-perpendicular ekugelezeni kwamanzi, ivimbela ngokuphumelelayo ukudlula kwabezindaba. Ngakolunye uhlangothi, lapho i-valve isendaweni evulekile, i-disc ihambisana nokugeleza, okuvumela ukudlula okungavinjelwe koketshezi. Lo mshini olula uvumela ukulawula okusheshayo nokunembayo kokugeleza, okwenza ama-valve evemvane e-PVC afanele uhla olubanzi lwezinhlelo zokusebenza.

Ukusetshenziswa kwezinto ze-PVC ne-UPVC ekwakhiweni kwamavalve ovemvane kunikeza izinzuzo eziningana. Lezi zinto azikwazi ukugqwala, zizenze zilungele ukusetshenziswa lapho i-valve ihlangana nemithombo yezindaba enolaka noma edlayo. Ukwengeza, i-PVC ne-UPVC ayisindi futhi kulula ukuyifaka, okwenza kube yisixazululo esingabizi kakhulu sezinhlelo zokusebenza ezihlukene zezimboni nezentengiso.

Ngaphezu kwalokho, amavalvu evemvane e-PVC kanye ne-UPVC aziwa ngezidingo zawo eziphansi zokunakekela kanye nempilo ende yesevisi, okuwenza abe ukukhetha okuthembekile kwezinhlelo zokulawula uketshezi. Lawa ma-valve ayatholakala futhi ngobukhulu obuhlukahlukene kanye nokucushwa ukuze avumelane nezidingo zokugeleza ezahlukene kanye nezidingo zokufakwa.

Sengiphetha, amavalvu evemvane e-PVC kanye ne-UPVC ayizingxenye ezibalulekile ezinhlelweni zokulawula uketshezi, anikeza ukulawula okuthembekile nokusebenzayo kokugeleza. Isimiso sabo esilula kodwa esisebenzayo sokusebenza, sihlanganiswe nezinzuzo zezinto zokwakha ze-PVC ne-UPVC, sibenza babe ukukhetha okuthandwayo ezinhlobonhlobo zezicelo ezimbonini ezinjengokuhlanza amanzi, ukucutshungulwa kwamakhemikhali, nezinhlelo ze-HVAC.
