Floating pneumatic ball pneumatic ball valve The ball of the pneumatic pneumatic ball valve is floating. Under the action of the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface at the outlet end to ensure that the outlet end is sealed. The floating pneumatic ball valve has simple structure and good sealing performance, but the load of the working medium borne by the ball is all transferred to the outlet seal ring, so it is necessary to consider whether the seal ring material can withstand the working load of the ball medium. This structure is widely used for middle and low pressure pneumatic ball valves.

Performance of non-metallic compensator and sleeve compensator
When we think of non-metallic compensator, we don't know what will come to our mind. Maybe we don't know the function of this product. The non-metallic compensator may be seen in many areas. Because of the consumption advantage of this product, people begin to pay more and more attention to this equipment.
The whole non-metallic compensator is made of rubber materials, with relatively high elasticity, air tightness, corrosion resistance and radiation resistance. The density inside the non-metallic compensator is relatively high, and there is also a high compressive capacity. Non metal compensators can be used in many areas where metal compensators cannot be used, such as those with complex geological conditions and large settlement amplitude. Non metal compensators can be used in these places.
Now we should all have a better understanding of this non-metallic compensator. If we can go to the relevant factory to see what we don't understand, we may fall in love with this kind of equipment from now on.
The two-way sleeve compensator has a telescopic core tube in both directions of the ordinary type outer sleeve, which compensates twice as much as the ordinary type grain, and is used for two-way compensation, reducing the length and cost of using two ordinary types.
Synthesis diagram and synthesis description of two-way sleeve compensator:
A two-way sleeve compensator is composed of a left end sleeve 2, a left end core tube 5, a right end sleeve 25, a right end core tube 23, a left end inner seal ring 4, a left end outer seal ring 8, a right end inner seal ring 26, a right end outer seal ring 24 and a connecting fastener, which is characterized in that there is a circular wedge conical space between the inner circle of the left end sleeve 2 and the two sides of the convex outer wall of the left end core tube 5, There is also a ring shaped tapered wedge space between the two sides of the inner bulge of the right end sleeve 25 and the outer circle of the right end core tube 23, and their respective ring shaped tapered wedge spaces are respectively equipped with the matching ring shaped tapered inner seal ring 4 at the left end, outer seal ring 8 at the left end, inner seal ring 26 at the right end, and outer seal ring 24 at the right end. 2. The bidirectional sleeve compensator according to claim 1, which is also characterized in that the inner and outer sealing rings at the left and right ends for sealing can be solid or virtual, that is, a V-shaped circular ring shaped groove is opened in the middle of the circular wedge cone of the sealing ring, the groove can be one or multiple, and the inner and outer sealing rings can use solid cores at the same time, The virtual core can also be used at the same time or mixed.
