Pneumatic ball valve is an important equipment to protect the pipeline during pipeline connection. During the use of the pipeline, the pneumatic ball valve will inevitably encounter thermal expansion and cold contraction. Of course, the thermal expansion and cold contraction of the pipeline will not be as obvious as the valve products, but when the pipeline is suddenly heated or cooled, it is very likely that the pipeline will suddenly become longer or shorter, This situation is harmful to the pipeline. Therefore, pneumatic ball valves are produced to prevent the pipeline from being damaged due to thermal expansion and cold contraction.
Pneumatic ball valve is a pipe joint with a certain expansion amount. What is the expansion amount? It means that there can be a certain distance between the two ends of the joint, which can be extended or shortened freely within the allowable range of the distance. Of course, the expansion amount is relatively limited. When the expansion amount is too large, the limiting device will work and eventually reach the maximum expansion displacement. The protection of the pneumatic ball valve to the pipeline is also perfectly reflected from the expansion and contraction. What does this mean? Pneumatic ball valve is specially used to protect the expansion and contraction of pipes. When the pipe is heated or cooled, the length of the pipe will be slightly extended or shortened. This length is very small, but if each connected pipe is extended or shortened at the same time, the expansion amount is relatively large, which may lead to the pipe being squeezed or the pipe joint being pulled off.
However, if the pneumatic ball valve is used for connection, this problem can be avoided. Each pneumatic ball valve can be lengthened or shortened freely. When the pipeline is heated and expanded, the pneumatic ball valve will be shortened. When the pipeline is cooled and shortened, the pneumatic ball valve will be lengthened to compensate for the expansion. Therefore, whether the pipeline becomes longer or shorter, it is assumed by the pneumatic ball valve, and the pipeline will not be affected, which can protect the pipeline. Pneumatic ball valve is an important equipment to protect the pipeline during pipeline connection. Through a lot of experience analysis, the service life of the pipeline with pneumatic ball valve is about twice as long as that of the pipeline without pneumatic ball valve. Therefore, in addition to connecting the pipeline, pneumatic ball valve is also an important feature of pipeline protection.
