Embodiment approach

[0025]As an embodiment of the present invention, the bellows 2 are corrugated structural design at the first ring groove and the second annular groove; UV glue is coated in the first ring groove and the second annular groove; When working, an arc-shaped expansion structure is formed during the expansion of the first expansion ring 35 and the second expansion ring 41, and the arcuate expansion structure and the corrugated structure corresponding to the bellows 2 match each other, and the first expansion ring 35 is increased. The second expansion ring 41 and the bellows area of ​​the bellows 2 improve the sealing effect, and the fixed effect is more secure, and the sealing property can be further improved by disposing in the first ring groove and the second annular groove.

[0026]As an embodiment of the present invention, the first rubber ring 34 and the second rubber ring 42 are provided with uniformly arranged projections 31 on the side side; when the fluid is passed through the press...

Abstract

The invention belongs to the technical field of compensators, in particular to a pressure compensator, which includes a housing, a bellows, a first connecting pipe and a second connecting pipe; the opposite sides of the first connecting pipe and the second connecting pipe A first annular groove and a second annular groove are opened respectively, and the positions of the first annular groove and the second annular groove are set corresponding to each other; the first annular groove and the second annular groove are jointly fixed with the same bellows; the The outer surfaces of the first connecting pipe and the second connecting pipe are sleeved together with the same shell; the present invention not only meets the compensation requirements for the axial deformation of the pipeline in the prior art, but also realizes the compensation requirement for local deformation of the pipeline. And it solves the problem that the compensation effect is weak when the lateral and angular displacement of the pipeline occurs, the structure is simple, and the practicability is high.

Description

Technical field[0001]The present invention belongs to the technical field of compensator, and is specifically a pressure compensator.Background technique[0002]Compensator habits are also called expansion festivals, or telescopic festivals. Composed of bellows, end tubes, brackets, flanges, and catheters constituting their working body. It belongs to a compensation element. The effective telescoping deformation of its working body bellows is used to absorb the size of the pipeline, the catheter, the container, or the like, or the axial, lateral and angular displacement of the pipeline, catheter, container, etc. Can also be used for noise reduction and vibration. It is widely used in modern industries. In order to prevent the heating pipe temperature from warming, the tubular deformation or damage is required due to thermal elongation or temperature stress, it is necessary to set the compensator on the pipe to compensate for the heat eluate of the pipe, thereby reducing the stress of ...
