Do you know the advantages of multi-ball rubber expansion joint?

Double sphere rubber expansion joint is composed of inner and outer rubber, cord fabric layer and steel wire ring, which is vulcanized and then loosely combined with metal flange or parallel joint. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems.
The working condition of the clamp is equivalent to a pressurized container, the axial force of the medium is completely borne by the clamp, and the bolt only bears the radial force of the clamp. Due to the limited width of the seal, the radial force is much smaller than the axial force. When the rubber expansion joint flange is connected, the bolt, however, bears all the axial force and the compression force of the gasket.
Double sphere rubber expansion joint good self-sealing role, sealing role by the medium in the pipe on the compression force of the rubber ring, the greater the pressure, the better the sealing performance. In order to prevent the leakage of media when the double sphere rubber expansion joint no pressure, the inner diameter of the rubber ring to be smaller than the outer diameter of the pipe end interface, the rubber ring in the end of the pipe interface with preload, can prevent the leakage of media in the absence of pressure. Compared with the flange, the larger the pipe diameter, the higher the pressure, the more prominent the advantages.
Double sphere rubber expansion joint pipe connection at the flexible state, there is a gap between the clamp and the end of the pipe, the pipe can have a small amount of activity in the clamp. Therefore, the double sphere rubber expansion joint adjacent to the two end pipes are allowed to have a specific turning angle. After the steel pipe is connected, there is a gap between the two steel pipe ends, allowing the pipeline to move axially, which can adapt to the expansion and contraction of the pipe The rubber ring connection between the pipes can effectively reduce the mechanical vibration of more than 0.7.
Double sphere rubber expansion joint good self-sealing role, sealing role by the medium in the pipe on the compression force of the rubber ring, the greater the pressure, the better the sealing performance.
