[0002] Water supply pipes can be used to transport and distribute water, which is equivalent to a transfer interface, responsible for connecting the starting end and the end end. Flexible rubber joints are set on the inlet and outlet sides of the water supply pipe to reduce the vibration and noise of the pipeline system.

[0003] When the pipeline system is running, the water flow in the pipeline will generate thrust to expand the flexible rubber joint, which may push the pipeline to produce a certain sliding deviation; when the water pressure is high, a large thrust will be generated along the axial direction of the pipeline. When the actual working axial displacement pressure of the rubber joint is less than the supporting force of the pipeline, the pipeline or equipment may be deviated at the least, and the connection may be damaged at the worst, causing the water supply system to fail to work normally. Therefore, it is necessary to design a flexible joint for water supply pipelines to solve the above problems.
