The invention relates to the technical field of bellows compensators, and discloses a bellows compensator with a built-in elastic connection structure, including a lower flange, the top of the lower flange is fixedly connected with a first connecting pipe, and the top of the first connecting pipe The top is fixedly connected with a first powerful magnet, and the top of the first powerful magnet is provided with a second powerful magnet, and the top of the second powerful magnet is fixedly connected with a first fixing tube. In the present invention, by adding the first connecting pipe, the first powerful magnet, the second connecting pipe and the limit seat, when the corrugated pipe is subjected to compression and stretching forces, a horizontal direction will be generated inside the first fixed pipe through the first powerful magnet. At the same time, the guide rod drives the limit seat to move laterally inside the second fixed seat, so as to achieve the purpose of compensating the length of the bellows and avoid the axial force causing damage to the butt joint when the bellows is compressed or stretched If the situation occurs, the service life of the butt joint is extended.
Description
technical field [0001] The invention relates to the technical field of bellows compensators, in particular to a bellows compensator with a built-in elastic connection structure. Background technique [0002] The bellows compensator is the most used safety device in the industrial pipeline network. In the project, the elastic deformation characteristics of the bellows are used to absorb or compensate the axial displacement caused by the physical changes of the distributed pipeline network, which mainly plays a role in ensuring the pipeline network. For the function of safe operation, the main component in the bellows compensator is the bellows, and the bellows of the thin-walled parts are sleeved with the relatively thicker wall thickness and directly fixedly connected. [0003] But in practical application, because the bellows moves frequently with the temperature or pressure of the conveying medium, it will inevitably involve the joints connecting the bellows and the connec...
