Elastic ball pneumatic pneumatic ball valve The ball of pneumatic pneumatic ball valve is elastic. The ball and valve seat seal ring are made of metal materials, and the sealing pressure is very high. The pressure of the medium itself cannot meet the sealing requirements, so external force must be applied. This valve is suitable for high temperature and high pressure media. An elastic sphere obtains elasticity by opening an elastic groove at the lower end of the inner wall of the sphere. When closing the channel, use the wedge head of the valve rod to expand the ball and compress the valve seat to seal. Loosen the wedge head before rotating the ball, and the ball will return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface. Pneumatic pneumatic ball valves can be divided into straight, three-way and right angle types according to their channel positions. The last two pneumatic ball valves are used to distribute media and change the flow direction of media.

In order to better grasp the characteristics of the device in the process of work, people can understand that the device has a very good effect in the realization of media flow switching, of course, the specific adjustment method is also very simple. In addition to this function, three pipelines are interconnected, and any two pipelines can be closed, so that each part of the whole can achieve a more ideal effect.
