Introduce of transmission expansion joint
The single-flange force transmission expansion joint is composed of loose sleeve expansion joint, short pipe flange, force transmission screw and other components
It can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, but cannot absorb the axial displacement.
It is mainly used for loose connection of pump, valve, pipeline and other accessories. During operation, the axial thrust can be transmitted back to the whole pipeline. This will not only improve the working efficiency, but also protect the pump, valve and other equipment.
