Explosion-proof high-pressure-resistant self-sealing rotary compensator

Abstract

The invention relates to the technical field of rotary compensators, and particularly discloses an anti-explosion high-pressure-resistant self-sealing rotary compensator which comprises an outer pipe and an inner pipe arranged in the outer pipe in a sleeved mode, a baffle is arranged on the end face of the outer pipe, and a first bearing is arranged between one side of the surface of the inner pipe and one side of the inner wall of the outer pipe. A connecting pipe is arranged on the end face of the inner pipe, a second bearing is arranged between the baffle and the connecting pipe, and a limiting assembly is arranged between the surface of the inner pipe and the inner wall of the outer pipe. The baffle is arranged on the surface of the outer pipe, the inner pipe is limited and fixed in cooperation with the first bearing and the second bearing, meanwhile, it is guaranteed that the inner pipe can rotate, the limiting assembly arranged between the inner pipe and the outer pipe is used, and the outer wall of the inner pipe can be supported through cooperation of a spring and an upper limiting rod; and after the inner pipe is thermally expanded, the anti-pressure capability of the inner pipe can be enhanced by utilizing the elastic force of the spring.

Description

technical field [0001] The invention relates to the technical field of rotary compensators, in particular to an explosion-proof and high-pressure resistant self-sealing rotary compensator. Background technique [0002] The rotary compensator is mainly used in pipeline compensation, and has a rotating function, which is suitable for pipelines that are prone to torsion. The pipeline compensator is also called an expansion joint or an expansion joint and an expansion joint. It is mainly used to compensate for the temperature change of the pipeline. However, when the existing rotary compensator is used in practice, it is not ideal to simply rely on the thickness of its own material to improve the anti-compression and explosion-proof ability. Moreover, the sealing performance between the inner tube and the outer tube of the existing compensator is also insufficient, and leakage often occurs, which affects the normal transportation of the pipeline.
