I-American Non Rising Stem yeSango elithambileyo lokutywina iValve

Izinto eziluncedo kwiValve yethu yeSango eNgaphumiyo

I-1) Isitywina esiphezulu sevalve sitywinwe ngamakhonkco okutywina erabha amathathu amile okwe-"O", kwaye amakhonkco amabini aphezulu "O" anokutshintshwa ngaphandle kokumisa amanzi.
2) Umzimba wevalve kunye nebhonethi ithatha "O" uhlobo lwerabha yokutywina isakhiwo seringi, esinokuqonda ukuzitywina.
3) Xa ivalve ivuleke ngokupheleleyo, ipleyiti yevalve iphezulu kunobubanzi bevalve, umzantsi womzimba wevalve ugudileyo ngaphandle kwesango, kwaye i-coefficient yokumelana nokuhamba incinci, ethintela into yokuba ipleyiti yevalve ilungile. ayivalwanga ngokuqinileyo ngenxa yenkunkuma evalela i-gasket.
I-4) I-valve stem nut kunye ne-plate yesango idibaniswe yi-T-slot, enegunya eliphezulu, kunye ne-radial friction force phakathi kweplate ye-valve kunye nomzimba we-valve uncinci kakhulu, kwaye ubomi benkonzo bude.
I-5) I-Anti-rust kunye ne-anti-corrosion unyango ithatha ukutshiza kwe-electrostatic ye-non-toxic epoxy resin hot-melt solidification powder.Umgubo unesiqinisekiso se-WRAS kunye ne-NSF, esusa ukungcoliseka kwesibini kumgangatho wamanzi kwaye yenza unikezelo lwamanzi lucoceke ngakumbi.
