When connecting with a socket joint, a flexible rubber ring is inserted between the socket joints. Utilizing the excellent elasticity of the rubber ring, it fits with the special sealing groove of the socket, fixing the gap between the socket joints to ensure an even annular gap, preventing debris from entering the pipeline and preventing medium leakage. Product features: simple operation, convenient construction, fast speed, low labor intensity, belongs to elastic joints, can withstand a certain displacement and vibration caused by external forces, has seismic performance, but has strict requirements on joint materials, suitable for areas with poor foundation and easy vibration.
