??Application of the rubber valve seals?

??Ball knows what is it? A ball is under different environmental conditions, can be manually driven, pneumatic or electric drive means driving means to achieve the opening and closing of the valve. As a rubber ring sealing element, which static sealing and dynamic sealing play an important role in various types of ball valves in sealing performance. . Rubber seal on the end face of the valve stem and can effectively prevent the leakage of all types of media, to ensure the normal operation of the valve system. Rubber seal is mounted on both ends of the surface of it belongs to the static sealing effect, is mounted on the valve body and valve stem hole genus dynamic sealing effect. Two types of sealing effect fully meet the design requirements of the ball.

??For the gas valve, in order to prevent leakage of gas medium through various channels, causing explosive, O embedded in the rubber seal at the leak, can effectively prevent the leakage of the valve clearance is less than 0.001μm, in order to achieve zero leakage, so it is particularly suitable for special occasions conditions need gas, dust and other media.

??Two-piece ball left and right body for the metal to metal contact is a static seal structure, in order to reduce or eliminate the sealing surface of the gap between them and choose the O-rubber seals for the sealing element in the design, when compared with medium pressure hour in a motionless state, the required sealing force is small, this time by the preload during assembly seals in resilient O-under, it can ensure that the left and right ends of the seal body; when the medium pressure rising, sealing with pressure also increases, sudden expansion, then the O-rubber seals effectively prevent leakage point gap between the two ends, the valve sealing performance is thus guaranteed.

??However, due to low friction O-shaped rubber seal and good self-lubricating, they complement each other play a good sealing effect. In order to ensure the valve seat and the valve body to form a good seal pair, the same machining a groove in the seat, the O-shaped rubber seal is mounted wherein the valve chamber when the medium pressure increases, driven by spring force to the valve seat spool displacement, high energy seal elastic rubber O-down, to ensure that the pipe-line seal case enable dynamic sealing effect in the pipeline, the first type of construction, the O shaped rubber seals belong to the same dynamic sealing structure.
