VSSJAFC detachable double flange transmission joint
The double flange transmission joint is composed of valve body, sealing ring, gland, telescopic short pipe and other main components. The joint is applicable to the pipe uniformly connected with flanges on both sides. During installation, adjust the installation length between the two ends of the joint and the flange, tighten the gland bolts diagonally and evenly to make them a whole with a certain displacement for installation. When repairing the transmission joint, it shall be adjusted according to the field dimensions. The double flange drive joint can transmit the reverse axial thrust to the entire pipeline in operation.
Performance of double flange transmission joint
1. It shall have high compression capacity to ensure the operation of the pipeline during crustal movement. It has high corrosion resistance. The expansion joints are buried underground all the year round, so it has high requirements for corrosion resistance.
2. It can move axially to eliminate the thermal expansion and cold contraction stress caused by seasonal changes or different media. The steel expansion joint is made of steel, and the rubber joint has strong corrosion resistance and flange connection.
3. It is easy to install and maintain, avoiding unnecessary trouble in the welding process. Special design process is adopted to strengthen the limit bolt to make the pipeline operation more reliable.

Double flange transmission joint application
In the installation process of double flange drive joint, when the temperature changes or the pipeline vibrates, it can play the role of expansion compensation. When the foundation settles, the displacement can be compensated to a certain extent to ensure no leakage of the seal. Secondly, the installation and disassembly of the double flange transmission joint is very convenient, which makes it connected with the water supply and drainage pipeline and the water tower, providing great convenience for the installation and disassembly of the pump water meter.
