Description

Technical Field

[0001] The utility model relates to the field of compensators, and more specifically, to a jacketed metal compensator. Background Art

[0002] The compensator is also called an expansion joint or telescopic joint. It is composed of a bellows and end pipes, brackets, flanges, conduits and other accessories that constitute its working body. It is a compensating element that mainly acts on the connection between pipelines.

[0003] After searching, the existing patent (publication number: CN214405119U) discloses a jacketed metal bellows compensator with an alarm interface, which includes a left flange, an outer compensator, an inner compensator, a right flange and an alarm interface. The alarm interface is a valve-controlled interface, which is sealed and connected to the outer wall of the pipe with an outlet of the outer compensator. The alarm interface and the outlet that are radially connected to the inner wall of the outer compensator are on the same circumference, and the positions of the two differ by 160° to 200°. The utility model pre-sets an alarm interface on the outer compensator and uses the interface to insert necessary sensors into the jacket. In addition to facilitating remote monitoring of the real-time temperature, pressure and flow rate of the heating medium in the jacket, this technical measure can obtain the operating quality information of the inner compensator in the first time. Since internal leakage can be discovered in time, users can greatly reduce process losses.

[0004] During the use of existing compensators, when the two ends of the compensator are connected to the pipeline, the connection is mostly fixed by flanges and bolts. After long-term use, the bolts are prone to rust inside the flange, causing the connecting threads between the bolts and the flange to get stuck, making it difficult for users to disassemble the compensator and the pipeline.

[0005] Therefore, a jacketed metal compensator is proposed to address the above-mentioned problem. Meanwhile, the above-cited patent document does not propose a relevant solution to solve the problem of difficulty in disassembling the compensator and the pipeline. Utility Model Content
