A compound universal hinged expansion joint comprises two universal expansion joint bodies, a middle connection tube and a middle connection plate. Each universal expansion joint body comprises an end tube, a corrugated tube, a vertical plate, a hinge plate, a pin shaft, a universal ring and a connection plate supporting base. The two ends of the middle connection plate are connected with the universal rings through connection plate pin shafts. Each connection plate supporting base is composed of a connection support, a support plate and a clamping plate. Each connection support is fixedly connected with the middle of the outer wall of the middle connection tube, each support plate is fixedly connected with the outer end face of the corresponding connection support, each clamping plate is fixedly connected with the corresponding support plate, and the middle connection plate axially penetrates through holes in the clamping plates and is in clearance fit with the through holes in the clamping plates to form a floating connection structure. The expansion joint is characterized in that the side edges of the clamping plates on the connection plate supporting base are further provided with limiting blocks, and the middle connection plate is clamped into open grooves in the limiting blocks and is in clearance fit with the open grooves. The expansion joint can absorb displacement of pipelines, prevent vibration and equally divide displacement of the corrugated tube.
Description
technical field [0001] The invention relates to a pipeline compensator, in particular to a composite expansion joint. Background technique [0002] Hinge-type expansion joints are widely used in the new compensation elements of thermal pipe networks because of their better compensation for lateral and angular displacements and the ability to withstand the thrust of blind plates. At present, the intermediate connecting plate of the compound hinge expansion joint is usually fixedly connected to the intermediate connecting pipe by welding. This connecting method cannot evenly distribute the displacement of the bellows, and the anti-vibration effect is poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the utility model proposes a compound universal hinge expansion joint which can absorb the displacement of the pipeline, prevent vibration and evenly distribute the displacement of the bellows. [0004] The present invention achieves technical...
