PVC Diaphragm Valve Mfundo ndi Zopangira

PVC (polyvinyl chloride) ndi UPVC (unplasticized polyvinyl chloride) amagwiritsidwa ntchito kwambiri popanga mavavu ndi zolumikizira chifukwa cha kukana kwawo kwamankhwala komanso kulimba kwawo. Pankhani ya ma valve a diaphragm, mfundo za ma valve a PVC diaphragm zimagwira ntchito yofunika kwambiri pakugwira ntchito kwawo.

Mavavu a diaphragm ndi mtundu wa valavu yomwe imagwiritsa ntchito diaphragm yosinthasintha kuwongolera kutuluka kwa madzi. Mfundo ya mavavu a PVC diaphragm imachokera pa kayendedwe ka diaphragm kuti azitha kuyendetsa madzi. Vavu ikatsegula, diaphragm imakwezedwa, kuti madziwo adutse. Mosiyana ndi zimenezi, valavu ikatsekedwa, diaphragm imakanikizidwa pampando wa valve, kulepheretsa kutuluka kwa madzi.

Kusankhidwa kwa PVC kapena UPVC kwa zida za diaphragm valve ndizofunikira chifukwa cha kukana kwawo kwa mankhwala komanso kusawononga. Zidazi ndizoyenera kunyamula madzi ambiri, kuphatikiza ma acid, alkalis, ndi zinthu zina zowononga, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mafakitale osiyanasiyana.

Mapangidwe a ma valve a PVC diaphragm ndi zoyikira ndizofunikira kuti azigwira bwino ntchito. Thupi la valve nthawi zambiri limapangidwa ndi PVC kapena UPVC, kupereka nyumba yolimba komanso yolimba ya diaphragm ndi zina zamkati. Diaphragm palokha imapangidwa ndi zinthu zosinthika, monga mphira kapena thermoplastic elastomers, zomwe zimalola kuti zisunthike m'mwamba ndi pansi kuti zisamayendetse madzi.

Kugwiritsiridwa ntchito kwa PVC ndi UPVC muzitsulo za valve diaphragm zimatsimikizira kuti ma valve ndi opepuka, osavuta kukhazikitsa, ndipo amafuna kukonzanso pang'ono. Kuphatikiza apo, zidazi ndizotsika mtengo, zomwe zimapangitsa kukhala chisankho chodziwika bwino m'mafakitale osiyanasiyana, kuphatikiza kuthirira madzi, kukonza mankhwala, ndi kupanga mankhwala.

Pomaliza, mfundo za ma valve a PVC diaphragm, kuphatikizapo kugwiritsa ntchito zipangizo za PVC ndi UPVC zopangira zida, zimapangitsa kuti ma valve awa akhale abwino kwambiri poyendetsa kutuluka kwa madzi m'mafakitale osiyanasiyana. Kukana kwawo kwamankhwala, kukhazikika, komanso kapangidwe kake koyenera kumawapangitsa kukhala yankho lodalirika la zosowa zamadzimadzi.
