Introduction: Many people would like to say that although the expansion joint and flexible waterproof sleeve belong to gate valve pipe fittings, their full play and application in the natural environment are not the same. What is the relationship between them? Here I am for you

Many people want to say that although Expansion joint And flexibility Waterproof casing Both of them belong to gate valve pipe fittings, but their full play and application in natural environment are not the same, so what is the relationship between them? Here I would like to make a brief description of the relationship between the two.
As we all know, the key application of expansion joint is mechanical equipment offset and thermal displacement of pipeline system software to absorb vibration and reduce noise. It is an indispensable part of gate valve installation, and provides great convenience for the disassembly and repair of gate valve in the middle and later stage Flexible waterproof casing A large pipe, also known as a guard pipe, is classified as normal operation. The expansion joint has large expansion offset, long service life, high bearing capacity and temperature. The flexible waterproof sleeve is suitable for buildings with vibration or strict moisture-proof requirements where it passes through the wall. The manufacturing technical standards of the two are close, and the working principle is similar. The general pipeline has no vibration under the maintenance of flexible waterproof sleeve, and the expansion joint is not in operation It is easy to cause pipe imbalance over a long period of time, so I think there is still a subtle relationship between the expansion joint and the flexible waterproof sleeve.

At present, the manufacturers of expansion joint and flexible waterproof casing are all over the western region and North China region of China, because the manufacturers usually manufacture both at the same time, which is more convenient for shop buyers.
