Furthermore, the screw hole runs through the injecting glue passageway, the screw thread diameter of screw hole is greater than the injecting glue passageway diameter.
Compared with the prior art, a novel screw injection joint have following advantage:
(1) multilayer annular seal ring gear and flange surface closely laminate on the valve body, form the line seal, can atress warp the laminating to the unevenness flange face seal ring gear that corrosion and japanning caused for a long time in a year, sealed effect is strengthened greatly, reduces to leak, guarantees the fail safe nature of valve body injecting glue.
(2) Valve body one side be the plane, reduced the raw and other materials loss of machine tooling, simplify manufacturing procedure to increase one deck screw thread shutoff before taking off the injecting glue rifle many, strengthen the shutoff effect.
