Hat type pneumatic valve ball profile, 2)

with pneumatic ball valve is widely used in oil and gas pipelines and oil production, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food, paper and other equipment. In jacking pipe removal is simple, quick, maintenance is convenient, fast and pneumatic ball valve. When pneumatic valve in the pipeline failure needs to be repaired, do not have to keep it from the pipe pneumatic valve, only removing the flange, bolts and nuts pneumatic valve cover, pneumatic valve stem and body assembly took down, take out the ball and pneumatic seat components. Sphere and pneumatic seat, can online repair. This service can save time and minimize lost production. Set into the pneumatic valve, floating ball ball pneumatic valve pneumatic valve. Coat float pneumatic valve nominal size or less DN. Is suitable for the compression spring, compression spring pre-tightening force is on the ball, make the pneumatic valve seat seal in any case, sealed performance is good close contact. And pneumatic valve seat of the wedge Angle of ° interface, the seat can be self-locking, the pipeline, when the pressure pneumatic valve seat, the seat will not produce any direction of displacement. Therefore, whether it be a pneumatic ball valve pneumatic valve pneumatic valve gate structure have an advantage. Maintenance checks found leakage of pneumatic valve and pneumatic valve seat is easy, if you increase the spring pre-tightening force, will inevitably increase pneumatic valve closing time. In order not to increase the pneumatic valve is closed, to add rubber o-ring seal face, time, solved the pneumatic valve pneumatic seat sealing surface leakage problem. With pneumatic ball valve fixed spring pre-tightening force is insufficient, can't adjust and control, large compression spring components, assembly difficulty. In order to solve, not this problem, the choice of spring material ANSI. ANSI spring stiffness, corrosion resistance and closed. In addition, the spring seat increase and adjusting nut, cylindrical pneumatic valve pneumatic seat and spring seat is turning the screw, the spring seat of adjustment and compression spring nut, the pneumatic valve seat assembly. Due to prior to installation, the ball has been compressed spring, easy to install. When the ball assembly, it can adjust the spring nut, this time, the ball spring pre-tightening force. If you want to increase the preloading adjusting nut to adjust.
