Izinto kunye neenketho zokutywina
Ukukhethwa kwezinto zokuvala kunye nee-O-rings kudlala indima ebalulekileyo ekusebenzeni kwevalvu. Umzekelo, ndihlala ndikhetha i-EPDM yokusetyenziswa kwamanzi ngenxa yokumelana kwayo kakuhle nobushushu kunye neekhemikhali. Kwizinto ezishushu ngakumbi, ndikhetha i-PTFE okanye i-FPM, ezibonelela ngokumelana okuphezulu kweekhemikhali. Ezi ndlela zindivumela ukuba ndenze ngokwezifiso ivalvu kwiintlobo ezithile zolwelo kunye neemeko zokusebenza.
Ingcebiso:Soloko unxibelelana nomenzi ukuqinisekisa ukuba izinto ezikhethiweyo ziyahambelana nesicelo esicetywayo.

Ndiyibonile indlela ukusebenza kwazo ngokutyibilikayo kunye neemfuno ezincinci zolondolozo ezinciphisa ngayo ixesha lokungasebenzi kunye neendleko zokusebenza. Ezi valve zikwahambelana neenjongo zozinzo ngokuba ziphinde zisetyenziswe kwaye zibe nobuhlobo nokusingqongileyo.
Ukusebenzisana nabavelisi beevalvu zebhola ze-upvc abathembekileyo kuqinisekisa ukufikelela kwiimveliso ezikumgangatho ophezulu ezihlangabezana nemigangatho yoshishino. Aba bavelisi bazisa ubuchule bobuchwephesha kwaye banamathela kwiziqinisekiso ezingqongqo, beqinisekisa iivalvu eziqinileyo nezihlala ixesha elide. Ngokukhetha umthengisi ofanelekileyo, ndingakwazi ukuhlangabezana neemfuno zayo nayiphi na iprojekthi yoshishino ngelixa ndiqinisekisa ukusebenza kakuhle nokuthembeka.
FAQ
1. Yintoni eyenza iivalvu zebhola ze-UPVC zahluke kwiivalvu zesinyithi?
Iivalvu zebhola ze-UPVC ziyamelana nokugqwala kunye nomonakalo weekhemikhali, ngokungafaniyo neevalvu zesinyithi. Uyilo lwazo olukhaphukhaphu lwenza kube lula ukufakela kwaye lunciphisa iindleko zokuthumela. Ndizifumana zingabizi kakhulu kwaye kulula ukuzigcina, nto leyo ezenza zilungele iiprojekthi zoshishino ezifuna ukuqina nokusebenza kakuhle.
