Description
Technical Field
The utility model belongs to the technical field of the compensator technique and specifically relates to a set up pipeline compensator of damping ring.
Background
The pipeline compensator is also called an expansion joint, is generally installed in a heat supply pipeline or a gas transmission pipeline in a segmented mode and is used for compensating the telescopic displacement of the pipeline, particularly a long-distance heat supply pipeline for transmitting high-temperature and high-pressure media, the wall thickness of the compensator is large, the strength of the compensator is high, and the axial displacement of the pipeline is absorbed more. The reliability requirements for the pipe compensator are therefore high.
At present, most of the common corrugated pipe compensators work in an internal pressure type mode. After the medium is introduced into the pipeline, the medium can enter the inner cavity of the corrugated pipe, namely the inner wall of the corrugated pipe is subjected to the pressure of the medium. When the pipeline extends or contracts because of thermal expansion and cold contraction, the corrugated pipe receives compressive or tensile acting force, and the trough department of corrugated pipe often can form stress concentration, and the pressure that the corrugated pipe inner wall bore in addition, the trough department of corrugated pipe appears leaking because of fatigue easily in the long-term use, and internal pressure formula corrugated pipe in case leak can make whole compensator inefficacy. Therefore, the pipeline compensator needs to be maintained or replaced regularly, so that the service life of the compensator is short, the workload of maintenance and replacement is large, and the cost is high.

The utility model aims at providing a set up pipeline compensator of damping ring. Through set up flexible damping ring in the trough of bellows, can effectively reduce the stress that bellows trough department formed to prolong pipeline compensator's life.
The purpose of the utility model is realized by adopting the following technical scheme:
the utility model provides a set up pipeline compensator of damping ring, includes bellows and honeycomb duct, and the honeycomb duct is established in the bellows, and the both ends of bellows are taken over respectively with a left side and are connected with the right side, and the outer end that takes over and the right side is equipped with left flange and right flange respectively, the one end of honeycomb duct is connected with the inner wall of taking over on a left side and is fixed, be equipped with flexible damping ring in the trough of bellows.
As the utility model discloses an optimized technical scheme, all the cover is equipped with flexible damping ring in all troughs of bellows.
As the preferred technical scheme of the utility model, flexible damping ring is the rubber circle.
As the preferred technical scheme of the utility model, the rubber circle includes fluorine rubber circle and silicon rubber circle.
As the utility model discloses a preferred technical scheme, the surface that left side was taken over and was taken over with the right side is equipped with the otic placode respectively, is connected through screw rod and nut component between the otic placode that the left side was taken over and the otic placode that the right side was taken over.
