Safe type anti-explosion self-sealing rotary compensator

Abstract

The invention discloses a safety type anti-explosion self-sealing rotary compensator, and relates to the technical field of self-sealing rotary compensators. The safety type anti-explosion self-sealing rotary compensator comprises a rotary cylinder body, the surface of the rotary cylinder body is slidably connected with a reducing pipe, and the surface of the rotary cylinder body is fixedly connected with a sealing gland and a sealing seat; and threaded grooves are formed in the surfaces of the sealing gland and the sealing seat, the inner walls of the threaded grooves are in threaded connection with compression bolts, and the surface of the rotating cylinder body is fixedly sleeved with a sealing material, a buffer ring, a filler and a rubber ring respectively. By arranging the sealing material, the sealing ring, the filler and the rubber ring, during use, when the rotary cylinder body buffers a pipeline, the sealing material and the buffer ring seal the rotary cylinder body, the rubber ring buffers the sealing seat, the sealing gland and the rotary cylinder body, meanwhile, the stability of the rotary cylinder body is improved, and the effect of good safety is achieved.

Description

technical field [0001] The invention relates to the technical field of self-sealing rotary compensators, in particular to a safe explosion-proof self-sealing rotary compensator. Background technique [0002] Self-sealing compensator, also known as expansion joint or telescopic joint, is composed of bellows (an elastic element) and end pipes, brackets, flanges, conduits and other accessories that constitute the main body of its work. It belongs to a compensation element. Utilize the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. due to thermal expansion and contraction, or to compensate for the axial, lateral and angular displacement of pipelines, conduits, containers, etc., In heat supply, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe heats up, to compensate for the thermal elongatio...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a safe explosion-proof self-sealing rotary compensator, which has the advantages of good safety and explosion-proof, so as to solve the problem that in the prior art, when the current common self-sealing rotary compensator is in use, only packing and gaskets are used to slow down The impact of thermal expansion and cold contraction on the compensator is less safe. At the same time, the expansion and contraction of the compensator is low, which easily increases the risk of compensator bursting and poses a dangerous problem to the personal safety of the staff.
