Description
Technical Field
The utility model relates to an expansion joint technical field especially relates to a compound ceramic expansion joint.
Background
The expansion joint is a flexible structure provided on the vessel shell or pipe to compensate for additional stresses due to temperature differences and mechanical shocks. As an elastic compensation element capable of freely stretching, the elastic compensation element has the advantages of reliable work, good performance, compact structure and the like, and is widely applied to chemical, metallurgical, nuclear and other departments. Expansion joints are also conventionally called compensators or expansion joints. It is composed of bellows, end pipe, support, flange and pipe.
The expansion joint is a flexible structure provided on the vessel shell or pipe in order to compensate for additional stresses due to temperature differences and mechanical shocks. The effective telescopic deformation of the working body corrugated pipe is utilized to absorb the dimensional change of pipelines, conduits, containers and the like caused by expansion and contraction due to heat and the like or compensate the axial, transverse and angular displacement of the pipelines, conduits, containers and the like. The compensator is arranged on the pipeline to compensate the thermal extension of the pipeline, so that the stress of the pipeline wall and the acting force acting on the valve member or the bracket structure are reduced.
As the expansion joint is an elastic compensation element capable of freely stretching, the expansion joint has the advantages of reliable work, good performance, compact structure and the like, and is widely applied to chemical, metallurgical, nuclear and other departments.
When the existing composite ceramic expansion joint is not used, dust is easily accumulated in the existing composite ceramic expansion joint, so that the expansion joint cannot be normally used, and the existing composite ceramic expansion joint is inconvenient to carry and install due to the material of the existing composite ceramic expansion joint, so that the composite ceramic expansion joint is provided.
