Umgaqo we-valve yokujonga i-PVC kunye nokubaluleka kwayo ekufakeni ivalve yeplastiki

I-PVC (i-polyvinyl chloride) kunye ne-UPVC (ipolyvin engafakwanga iplastiki) zisetyenziswa ngokubanzi ekwenzeni izifakelo zevalvu zeplastiki ngenxa yokuqina kwazo, ukuxhathisa kweekhemikhali, kunye nokufikeleleka kwazo. Ezi zinto zisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo, kubandakanywa ukunyanga kwamanzi, ukunkcenkceshela, kunye nemibhobho yamanzi. Elinye icandelo elibalulekileyo lokufakelwa kwevalvu yeplastiki yivalve yokujonga i-PVC, edlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi kunye nokuthintela ukubuya umva.

Umgaqo wevalve yePVC yokujonga usekwe kwindlela elula kodwa esebenzayo. Iqukethe i-hinged flap okanye i-swinging disc evumela ukuba ulwelo luhambe kwicala elinye ngelixa likhusela ukuhamba okubuyela umva. Xa ulwelo luhamba ngendlela efunwayo, uxinzelelo lwamanzi luphakamisa i-flap, luvumela ukuba ludlule kwivalve. Nangona kunjalo, xa ukuhamba kuyeka okanye ukubuyisela umva, i-flap ivala phantsi kobunzima bayo, ukukhusela nayiphi na i-backflow. Lo matshini uqinisekisa ukuba i-fluid ihamba kuphela kwicala elijoliswe kuyo, igcina ukusebenza kakuhle kunye nokhuseleko lwenkqubo.

Ukubaluleka kweevalvu ze-PVC zokujonga kwi-valve yeplastiki yokufakelwa kweevalvu ayikwazi ukugqithiswa. Banceda ekuthinteleni ukungcoliseka kwamanzi acocekileyo kunye nokubuyela umva kwamanzi angcolileyo, ukuqinisekisa ukucoceka kokunikezelwa kwamanzi. Kwiinkqubo zokunkcenkceshela, ii-valve ze-PVC zokuhlola zinceda ukugcina uxinzelelo kunye nokuhamba kwamanzi, ukukhusela umonakalo kwinkqubo kunye nokuqinisekisa ukuhanjiswa kwamanzi ngokufanelekileyo. Kwiinkqubo zemibhobho, ezi zivalo zithintela ukuguqulwa kwamanzi amdaka okanye amanzi amdaka, ukunciphisa umngcipheko wokuvala kunye nokugcina ucoceko lwenkqubo.

Ngaphaya koko, iivalvu ze-PVC zokujonga kulula ukuzifaka kwaye zifuna ukugcinwa okuncinci, kuzenze zibe sisisombululo esinexabiso eliphezulu kwizicelo ezahlukeneyo. Ukuhambelana kwabo kunye ne-PVC kunye ne-UPVC izinto kubenza babe lolona khetho lufanelekileyo lofakelo lwevalvu yeplastiki, ukuqinisekisa ukuba inkqubo yokulawula ukuhambahamba ingenamthungo nethembekileyo.

Ukuqukumbela, umgaqo we-valve yokujonga i-PVC ngumba osisiseko wokufakelwa kwevalvu yeplastiki, edlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi kunye nokuthintela ukubuya umva. Ngokusetyenziswa ngokubanzi kwezinto zePVC kunye ne-UPVC kumashishini ahlukeneyo, ukubaluleka kweevalve zokujonga i-PVC akunakuhoywa. Umatshini wabo olula kodwa osebenzayo, udityaniswa nokuqina kunye neemfuneko zogcino oluphantsi, zibenza babe yinxalenye eyimfuneko kwizifakelo zevalvu yeplastiki.
