Melemo ea Valve ea Rona e sa Rising Stem Soft Ho Tial Gate
1) Tiiso e ka holimo ea valve e tiisitsoe ka mehele e meraro ea "O" -e entsoeng ka rabara, 'me mehele e ka holimo ea "O" e nang le sebōpeho sa rabara e ka nkeloa sebaka ntle le ho emisa metsi.
2) 'Mele oa li-valve le bonnet li amohela sebopeho sa "O" sa mofuta oa rabara se tiisang, se ka khonang ho itiisa.
3) Ha valve e bulehile ka ho feletseng, poleiti ea valve e phahame ho feta bophara ba valve, karolo e ka tlaase ea 'mele oa valve e boreleli ntle le groove ea heke,' me coefficient ea ho hanyetsa phallo e nyenyane, e thibelang ketsahalo ea hore poleiti ea valve ke e sa tiisitsoeng ka thata ka lebaka la litšila tse thibelang gasket.
4) Letlapa la li-valve le letlapa la heke li kopantsoe ke T-slot, e nang le matla a phahameng, 'me matla a ho ferekanngoa ha radial pakeng tsa plate ea valve le' mele oa valve o monyenyane haholo, 'me bophelo ba tšebeletso bo bolelele.
5) Kalafo e khahlanong le mafome le anti-corrosion e amohela ho fafatsa ka electrostatic ea epoxy resin e se nang chefo e chesang e qhibilihisang phofo e tiileng.Phofo e na le setifikeiti sa WRAS le NSF, se felisang tšilafalo ea bobeli ho boleng ba metsi mme se etsa hore phepelo ea metsi e hloeke haholoanyane.
