2.2 Valve seat
(1) The floating design is adopted for the valve seat to reduce the processing difficulty and ensure that the center line of the valve seat coincides with the center point of the spherical surface of the hemisphere, thus improving the sealing performance. There is a gap between the valve seat and the valve body. During assembly, the use of hemispherical positioning can automatically align the center line, ensuring full contact between the sealing surface of the valve seat and the spherical surface of the hemispherical body, solving the leakage caused by machining accuracy errors, and improving the service performance and life of the pneumatic ball valve.

Although the pneumatic ball valve industry has a good prospect, it still needs our continuous efforts. At this time, it is better to continue scientific research, so that we can really take advantage of this aspect. This is not only to promote the development of the company, but also to promote the better progress of the entire industry. It is really clear about the prospect, the future of the industry, and the perspective of development. These aspects can not be underestimated to promote the whole industry. Only when everyone in the industry is constantly working hard, constantly uniting and competing, can we finally better promote the progress of the industry.
