The working principle is as follows:
when the expansion joint works, the first connecting pipe and the second connecting pipe are connected to the pipeline and used for absorbing axial or radial displacement of the pipeline caused by expansion with heat and contraction with cold, installation deviation, vibration and the like.
The expansion joint absorbs the pressure thrust generated by the expansion joint due to the internal pressure through the force bearing assemblies fixed on the first support plate and the second support plate, wherein the pressure in the inner cavity of the expansion joint is the same as that of the pipeline system when the expansion joint works normally; because the corrugated pipe in the expansion joint has certain flexibility, in the process of bearing pressure in the inner cavity of the expansion joint, the expansion joint expands towards two ends, and the internal pressure thrust generated by expansion is transmitted to a pipeline system, so that the pipeline is damaged. The first support plate is welded on the first connecting pipe, the second support plate is welded on the second connecting pipe, the first support plate and the second support plate are connected through the force bearing assembly, the axial movement capacity of the first support plate and the second support plate is limited, and the expansion joint cannot expand due to internal pressure thrust generated by the expansion joint, so that a pipeline system is protected.
