Umgaqo weValve ye-PVC ye-Diaphragm kunye neZifakelo
I-PVC (i-polyvinyl chloride) kunye ne-UPVC (i-polyvinyl chloride engaxutywanga) zisetyenziswa ngokubanzi ekwenzeni iivalvu kunye nokufakelwa ngenxa yokuxhathisa kwazo iikhemikhali kunye nokuqina. Xa kuziwa kwiivalvu ze-diaphragm, imigaqo ye-PVC ye-diaphragm valves idlala indima ebalulekileyo ekusebenzeni kwazo.
Izivalo ze-diaphragm luhlobo lwesivalo esisebenzisa i-diaphragm eguquguqukayo ukulawula ukuhamba kwamanzi. Umgaqo emva kwe-PVC diaphragm valves isekelwe kwintshukumo ye-diaphragm ukulawula ukuhamba kolwelo. Xa ivalve ivuliwe, i-diaphragm iyaphakanyiswa, ukuvumela ulwelo ukuba ludlule. Ngokuchasene noko, xa ivalve ivaliwe, i-diaphragm icinezelwe kwisitulo sevalve, ithintela ukuhamba kolwelo.
Ukukhethwa kwe-PVC okanye i-UPVC yokufakelwa kwe-valve ye-diaphragm ibalulekile ngenxa yokuchasana kweekhemikhali kunye neempawu ezingabonakaliyo. Ezi zixhobo zilungele ukuphatha uluhlu olubanzi lwamanzi, kuquka i-acids, i-alkalis, kunye nezinye izinto ezidliwayo, ezizenza zilungele ukusetyenziswa kwezoshishino ezahlukeneyo.
Uyilo lweevalvu ze-PVC ze-diaphragm kunye nezixhobo zibalulekile ekusebenzeni kwazo ngokufanelekileyo. Umzimba wevalvu wenziwa nge-PVC okanye i-UPVC, ebonelela ngendlu eyomeleleyo neyomeleleyo ye-diaphragm kunye nezinye izinto zangaphakathi. I-diaphragm ngokwayo yenziwe ngezinto eziguquguqukayo, ezifana nerabha okanye i-elastomers ye-thermoplastic, evumela ukuba inyuke kwaye ihle ukulawula ukuhamba kolwelo.
Ukusetyenziswa kwe-PVC kunye ne-UPVC kwi-valve ye-diaphragm iqinisekisa ukuba iivalve zilula, zilula ukuzifaka, kwaye zifuna ukugcinwa okuncinci. Ukongeza, ezi zixhobo azibizi kakhulu, zizenza zibe lukhetho oludumileyo kumashishini ahlukeneyo, kubandakanya nokucocwa kwamanzi, ukusetyenzwa kweekhemikhali, kunye nokuveliswa kwamayeza.
Ukuqukumbela, imigaqo ye-PVC ye-diaphragm valves, idibaniswe nokusetyenziswa kwe-PVC kunye ne-UPVC yezinto zokufakelwa, yenza ezi zivalo zibe yinto ekhethekileyo yokulawula ukuhamba kwamanzi kuluhlu olubanzi lwezicelo zoshishino. Ukuxhathisa kwabo kweekhemikhali, ukuqina, kunye noyilo olusebenzayo lubenza babe sisisombululo esithembekileyo kwiimfuno zokuphatha ulwelo.
