A new high pressure pipeline rotary compensator

Abstract

The invention discloses a novel high-pressure pipeline rotating compensator, and belongs to the technical field of pipeline supporting piping, in particular structures applied to heat pipeline compensating devices. The novel high-pressure pipeline rotating compensator comprises an outer connecting pipe B and an outer connecting pipe A which are inserted in each other; an outer convex ring is arranged on the outer connecting pipe A; an inner bearing platform and a gap bridge are arranged on the outer connecting pipe B; an inner boss is arranged on the gap bridge; a sealing component B, a sealing component A and a sealing seat are sequentially arranged outside along the outer connecting pipe A. According to the technical scheme, the novel high-pressure pipeline rotating compensator has the advantages of being high in precision, small in damage due to pressing, high in bending resistance and bearing capacity, free of limitation from medium flowing direction, outstanding in sealing performance, safe and reliable in long-term running of pipelines, and convenient to maintain.

Description

technical field [0001] The invention relates to a new type of high-pressure pipeline rotary compensator, which belongs to the technical field of pipeline supporting pipe fittings, especially for the structure of thermal pipeline compensation devices, and specifically belongs to the thermal pipeline used in petroleum, chemical industry, light industry, heat power, metallurgy and other industries Technical field of compensating device structures. Background technique [0002] Due to the temperature change of the transmission medium, the thermal pipeline will inevitably cause thermal expansion and contraction of the pipeline, and the expansion and contraction deformation of the pipeline will appear in the form of axial thrust or axial displacement that is not conducive to the safe operation of the pipeline. Under normal circumstances, pipeline compensation devices are installed in thermal pipelines to absorb or compensate pipeline deformation. Pipeline compensators in the prio...
