Problems solved by technology
[0003] Aiming at the deficiencies of the prior art, the present invention proposes an enhanced corrugated compound compensator that can solve the problem of poor welding processability of the diversion tube. The connection between the connecting pipe and the intermediate connecting pipe avoids the impact of instantaneous medium pressure and significantly prolongs the service life of the compensator

The invention discloses an intensified-type double corrugated compensator. The intensified-type double corrugated compensator comprises a left-end connecting pipe, a right-end connecting pipe and a middle connecting pipe, and corrugated pipes are connected to the left end and the right end of the middle connecting pipe respectively; the corrugated pipes at the left end and the right end of the middle connecting pipe are connected with the left-end connecting pipe and the right-end connecting pipe respectively; a left guide cylinder and a right guide cylinder are arranged on the inner sides of the corrugated pipes at the left end and the right end of the middle connecting pipe respectively; the left guide cylinder and the right guide cylinder are oppositely arranged, the left end of the left guide cylinder is fixedly connected to the inner wall of the left-end connecting pipe, and the right end of the right guide cylinder is fixedly connected to the inner wall of the right-end connecting pipe. The intensified-type double corrugated compensator is further characterized in that the right end of the left guide cylinder and the left end of the right guide cylinder are sleeved in a gap mode; annular rings are coaxially arranged on the outer walls of the straight sections of the corrugated pipes respectively in a sleeving mode, and intensifying connectors are formed in a fixedly-welded mode. According to the intensified-type double corrugated compensator, the welding manufacturability is good, impact resistance is achieved, it can be avoided that granular substances in media enter inner cavities of the corrugated pipes, and the service life is long.
Description
technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to a corrugated compound compensator. Background technique [0002] The bellows compensator is a commonly used pipeline compensator. In order to meet the relatively large axial compensation needs in the actual use of the pipeline network, the bellows compound compensator is often used. The bellows compound compensator is generally equipped with two bellows. The inner side of the bellows is respectively provided with guide tubes. The existing corrugated compound compensator has the following defects: the two guide tubes are arranged along the direction of the pipeline medium. Although they can guide the flow of the medium, one of the two guide tubes is welded to the inner wall of the intermediate connecting pipe. For a long distance, the manufacturability of welding is poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present ...
