Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compensating thermal pipelines, in particular to a translational and rotational comprehensive compensating thermal pipeline. Background Art
[0002] The translational and rotational comprehensive compensation thermal pipeline is a device used to compensate for the thermal expansion, contraction and deformation of the thermal pipeline caused by temperature changes or external loads. The function of the translational and rotational comprehensive compensation thermal pipeline is to absorb the thermal expansion, contraction and deformation of the pipeline through the deformation of the elastic element, thereby reducing the impact of the force and deformation of the pipeline system on the equipment and structure, and ensuring the safe operation of the pipeline system. Specifically, the translational compensation device can achieve longitudinal compensation of the pipeline through telescopic joints or expansion joints, so that the pipeline can freely expand and contract when the temperature changes. The rotational compensation device achieves lateral compensation of the pipeline through bending joints or corner joints, so that the pipeline can rotate or bend when subjected to external loads, thereby reducing the impact on the supporting structure. Translational and rotational comprehensive compensation thermal pipelines are usually used in thermal pipeline systems, such as chemical plants, power plants, petrochemicals, metallurgy and other industrial fields.
[0003] However, when some existing rotary compensators are used, most of them are connected to the pipeline by welding. Since the welding method is relatively complicated, a lot of time is consumed in the welding process, which affects the commissioning of the pipeline. Therefore, this problem needs to be solved.
