The correct way to open the installation sequence of bendable rubber joints

Flexible rubber joints are mainly used to connect valve pipes. It plays the role of vibration damping and noise reduction as well as preventing pipeline displacement. The main role of bendable flexible rubber joints is: an important skill that cannot be replaced by metal joints. The bendable flexible rubber joint can not only apply the axial and radial deflection displacement of both ends of the pipeline. The adaptability of the pipeline system to thermal expansion and contraction, and the ability to install. It can absorb the noise and vibration generated by the operation of pumps, fans, compressors and other equipment in the pipeline system.
 
Both sides of the bendable rubber joint are connected by a flange and can be moved. Therefore, rubber joints are very suitable for the connection of valves and pipes. The installation is convenient, and the bendable rubber joint is often installed at the front of the flange, which can effectively protect the valve from damage and indirectly extend the life cycle of the valve, so the bendable rubber joint is often seen in the pipeline valve.
Bendable rubber joints so and valves for the correct installation sequence: rubber soft joints -- check valve -- gate valve.
 
1. When installing the bendable rubber joint, the bolt in the bolt should reach to the outside of the joint, the bolt at one end of the flange needs to be tightened diagonally for this method repeatedly to avoid pressure deviation, the bendable rubber joint should use a wrench for uniform force tightening, never use a force bar to make the live joint become slippery, fracture and so on, so be sure to check more often to avoid loosening and so on. Even water seepage may occur.
 
2. Flexural rubber joints have an interval of displacement, so in the process of installation must not exceed the displacement limit, if so installed out of the flexural rubber joint will not play its original displacement role.
 
3.Therefore, the rubber joint must be installed in a natural state during installation. Just tighten it diagonally against the pipe flange connection. Adjustment can be made slightly. In the process of later use, regular maintenance should be carried out from time to time.
