Vharuvhu yeGedhi reWedge yemafuta En1984 China fekitori
Chii chinonzi Gate valve yemafuta?
Semavharuvhu egedhi re wedge akajairika, zvikamu zvekuvhura nekuvhara zvevharuvhu regedhi remafuta igedhi, rakaita se wedge, ndicho chikonzero nei zvichinzi vharuvhu regedhi re wedge. Vharuvhu regedhi re wedge rinogona kuvhurwa zvizere uye kuvharwa zvizere uye harigone kugadziriswa nekupwanywa. Vharuvhu regedhi rakagadzirwa kuti rishandiswe kuvhura zvizere kana kuvharwa zvizere, nekuti nekuda kwechimiro chema obturators ayo ane chimiro che wedge, dai raizoshandiswa rakavhurika zvishoma, paizova nekurasikirwa kukuru kwekumanikidzwa uye nzvimbo yekuvharira ichakuvadzwa kana mvura yarova.Chinhu chikuru chevharuvhu yeDIN-EN wedge gate ndechekuti nzvimbo yayo yekuvharira iri pakati pe "gate" nechigaro chayo yakati sandara, izvo zvinoguma nekurasikirwa kudiki kwekumanikidzwa.
