What should be paid attention to when installing dismantling joint

2021.03.24

Dismantling joints are generally used with gate valves and check valves, but this requirement is not enough. When designing the telescopic limit joint program, in addition to considering all normal actual operating procedures, regular inspection and maintenance requirements should also be considered. Especially in the case of maintenance of mechanical equipment and gate valves, there is still working pressure in the pipeline behind the gate valve.

At this time: According to the design plan, install the dismantling joint after the gate valve according to the feed amount. In addition, from the perspective of integrity and economic development, a gate valve should be installed on the pipeline behind the telescopic limit joint for regular inspection and maintenance. The dismantling joint can be modified, and limit switch equipment can be installed. For example, if two gate valves are installed on the pipeline, a telescopic limit joint can be installed between the two gate valves.


The dismantling joint is suitable for both sides and loose flanges. When installing, adjust the connection length on both sides of the product, tighten the base bolts of the screw cover in a symmetrical manner, and then adjust the limit switch nut. In this way, the pipeline can be expanded and contracted freely, and the amount of expansion and contraction can be locked to ensure the safe operation of the pipeline. The dismantling joint is suitable for both sides of the pipe connection, no welding, reasonable configuration, sealing, quick and convenient installation
