I-PVC (i-polyvinyl chloride) ne-UPVC (i-polyvin chloride engafakwanga ipulasitiki) yizinto ezisetshenziswa kakhulu ekwenzeni izinsimbi zamavalvu.

Lezi zinto ziyaziwa ngokuqina kwazo, ukumelana namakhemikhali, kanye nokuthengeka kwazo, okuzenza zibe ukukhetha okudumile kwezicelo ezahlukahlukene zezimboni nezindawo zokuhlala. Amavalvu e-diaphragm, ikakhulukazi, ayizingxenye ezibalulekile ezinhlelweni eziningi zokulawula uketshezi, futhi ukuqonda izimiso ezingemuva kwamavalvu e-diaphragm e-PVC kunganikeza imininingwane ebalulekile ekusebenzeni kwawo nasekusetshenzisweni kwawo.

Umgomo we-valve ye-PVC diaphragm ilele ekwakhiweni kwayo, okuhlanganisa i-diaphragm eguquguqukayo ebekwe ukuze ilawule ukugeleza koketshezi ngaphakathi kwevalvu. Lapho i-valve isendaweni evaliwe, i-diaphragm ivala umzimba we-valve, ivimbele ukugeleza koketshezi. Lapho i-valve ivuliwe, i-diaphragm iguquguquka isuke emzimbeni we-valve, ivumele uketshezi ukuba ludlule. Lo mshini olula kodwa osebenzayo wenza amavalvu e-PVC e-diaphragm afanele ukulawula ukugeleza koketshezi oluhlukahlukene, okuhlanganisa izinto ezibolayo nezilimazayo.

Ukusetshenziswa kwe-PVC ne-UPVC ekufakweni kwamavalvu e-diaphragm kunikeza izinzuzo ezimbalwa. Lezi zinto azikwazi ukumelana nokugqwala, okuzenza zilungele ukuphatha amakhemikhali nama-asidi anolaka. Ukwengeza, amavalvu e-PVC kanye ne-UPVC alula futhi kulula ukuwafaka, ehlisa izindleko zabasebenzi nezokulungisa. Ingaphakathi lawo elibushelelezi liphinde linciphise ukungqubuzana koketshezi, okuholela ekulawuleni ukugeleza okuphumelelayo nokunciphisa ukusetshenziswa kwamandla.

Ngaphezu kwalokho, ukufakwa kwamavalvu e-PVC kanye ne-UPVC kuyatholakala ngosayizi nokuhlelwa okuhlukahlukene, okuwenza afanelekele ukusetshenziswa okuhlukahlukene ezimbonini ezinjengokuhlanza amanzi, ukucutshungulwa kwamakhemikhali, nezinhlelo zokunisela. Ukuguquguquka kwazo kanye nokusebenza kahle kwezindleko kube nomthelela ekuthathweni kwazo okusabalele kuzo zombili izimo zezimboni nezindawo zokuhlala.

Sengiphetha, isimiso se-PVC diaphragm valves, esihlanganiswe nokusetshenziswa kwezinto ze-PVC ne-UPVC, sigcizelela ukubaluleka kwalezi zingxenye ezinhlelweni zokulawula uketshezi. Ukusebenza kwabo okuthembekile, ukumelana namakhemikhali, kanye nokusebenza kahle kwezindleko kubenza babaluleke kakhulu ezinhlelweni ezihlukene, futhi ukuqhubeka kwabo nokuthuthuka nokuqamba okusha kuzothuthukisa amakhono abo esikhathini esizayo.
