V-ball leaks common problems and solutions (1) V-ball gland leak causes: AO-ring damage. Solution: Replace the O-ring. (2) V-type valve flange leak causes: AV-type valve flange gasket loses its elasticity; Solution: Replace the flange gasket. B. flange gasket dislocation; solution, re-placed in the flange gasket sealing surface position. (3) the outer V-ball method causes the seal seat leakage test: AO-ring or graphite ring damage; Solution: Replace the O-ring or a graphite ring. Fixed Ball Ball: The ball valve is fixed, no movement after compression. All with a floating ball valve fixed valve seat, by medium pressure, the valve seat to move, so that the ball seals pressed on, in order to ensure the seal. Usually with the ball, the lower shaft with bearings Weifang valve operating torque small, suitable for high pressure and large diameter valves. To reduce the valve operating torque and increase the reliability of the seals, valve seals has emerged in recent years, both in Shandong special lubricant pressure injection valve sealing surface to form a layer of film V-ball manufacturers, namely enhanced sealing , but also reduce operating torque, more suitable for large diameter high pressure valve.
