Electric ball valve is an important equipment to protect the pipeline during pipeline connection. During the use of the pipeline, the electric ball valve will inevitably encounter thermal expansion and cold contraction. Of course, the thermal expansion and cold contraction of the pipeline will not be so obvious as the valve products, but when the pipeline is suddenly heated or cooled, it is likely that the pipeline will suddenly become longer or shorter, This situation is harmful to the pipeline. Therefore, people have produced electric ball valves to prevent the pipeline from being damaged due to thermal expansion and cold contraction.
The electric 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. And the protection of the electric ball valve to the pipeline is also perfectly reflected from the expansion and contraction. What does this mean? The electric ball valve is special for protecting 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 electric ball valve is used for connection, this problem can be avoided. Each electric ball valve can be lengthened or shortened freely. When the pipeline is heated and expanded, the electric ball valve will be shortened. When the pipeline is cooled and shortened, the electric ball valve will be lengthened to compensate for the expansion. Therefore, whether the pipeline becomes longer or shorter, it is assumed by the electric ball valve, and the pipeline will not be affected in any way, which can protect the pipeline. The electric ball valve is an important equipment to protect the pipeline during the pipeline connection process. Through a lot of experience analysis, the life of the pipeline with the electric ball valve is about one time longer than the pipeline without the electric ball valve. Therefore, in addition to connecting the pipeline, the electric ball valve is also an important feature of protecting the pipeline.
