Improvement of Ball Valves Sealing Performance

June 13, 2017 , 12:00 am - June 11, 2027 , 12:00 am EST

Present Situation and Analysis of Ball Valve Sealing

Cast stone ball valve is an ideal disc for ash pipeline and its back seal will directly affect the quality and service life of itself. In the past, it adopted an O-shaped rubber seal structure in which an O-shaped sealing ring was placed in an annular groove machined on the shaft and then fitted it into a hole formed in a sleeve-like part to form the seal of the shaft and the hole. The sealing performance of this structure depends on the amount of interference at the time of design, that is, the compression of the O-shaped seal ring and the machining accuracy of the hole and shaft parts. If interference is too small, the seal performance will be poor; too large, the assembly will be easy to squeeze the O-shaped seal ring, causing sealing failure.
