Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline compensators, and particularly relates to a corrugated rotary compensator. Background Art

[0002] Pressure pipelines with fixing devices at both ends will deform due to thermal expansion and contraction, and compensators need to be installed to prevent deformation and damage of the pipeline. In recent years, there are more and more pipelines under high temperature and high pressure conditions, which requires the installation of a compensator element in the pipeline that can provide a large amount of compensation. The rotational compensation method can provide a large amount of compensation. A typical structure of this compensator is: the rotational compensator is installed on two vertical rotating arms with a certain spacing. When the straight pipelines on both sides expand thermally, the two compensators will be pushed to rotate, thereby achieving the purpose of compensating for the thermal expansion and displacement of the pipeline.

[0003] At present, there is a rotary compensator that uses sealing filler to fill between the outer rotating sleeve and the inner rotating sleeve. From the perspective of usage effect, this rotary compensator is more prone to leakage under high temperature conditions. There is a large friction resistance between the sealing filler and the outer rotating sleeve and the inner rotating sleeve. The design of its rotating structure also has the defect of poor operation. In addition, affected by the installation construction and pipeline deformation, the compensator is prone to misalignment and leakage. Utility Model Content

The tightness between the correction springs can be adjusted during expansion and contraction, thereby continuing to maintain the working state, solving the problem of existing use effects that this type of rotary compensator is prone to leakage under high temperature conditions, there is a large friction resistance between the sealing packing and the outer rotating sleeve and the inner rotating sleeve, and the design of its rotating structure also has the defect of poor operation.
