Cause Analysis of Ball Valve Leakage

Ball valves are also widely used in the gasification field of coal chemical plants, because they contain special media such as solid particles  sulfur under working conditions,  at the same time have good sealing, but leakage occurs during our use. Pneumatic regulating ball valve can realize proportional adjustment. It can be used together with two-position five-way solenoid valve  control box to realize on-off control. V-shaped ball valve core is designed with a V-shaped notch with a special shape, which has accurate interception properties  control functions. , suitable for various control occasions. Reliability of the upper limit of the pneumatic cut-off valve: the valve body is an integral structure, which is sturdy  durable, the operation is  affected by the pipeline pressure,  the leakage of the valve body can be avoided. The electric explosion-proof butterfly valve is composed of a V-type valve body, a ZSQ-type pneumatic actuator  other accessories. It is a control valve with a quarter-turn structure. The V-type ball valve does  require repairs for a long time  has a long service life.

There may be unreasonable design of the stem packing ball, the concentricity tolerance of the ball stem  the unreasonable selection of materials caused during the valve stem switching. Reduce the stem diameter  then stem along the leakage axis of the flow valve medium.
