Compensator is also known as expansion joint, or expansion joint. The utility model is composed of a bellows (an elastic element) constituting the main body of the bellows and accessories such as an end pipe, a bracket, a flange, a conduit, etc. The utility model belongs to a compensation element. The effective expansion deformation of bellows is used to absorb the size changes of pipelines, conduits and containers caused by thermal expansion and cold contraction, or to compensate the axial, transverse and angular displacements of pipelines, conduits and containers. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. In heating, in order to prevent pipeline deformation or damage caused by thermal elongation or thermal stress during heating, compensators need to be installed on the pipeline to compensate the thermal elongation of the pipeline, thereby reducing the stress of the pipe wall and the force acting on the valve or support structure. Axial type is mainly used to compensate the axial displacement, but it can also compensate the lateral displacement or the combined axial and transverse displacement. It has the ability to compensate the angular displacement. However, the general type of compensator should not be used to compensate the angular displacement. The transverse type mainly absorbs transverse displacement and a small amount of axial displacement. The angular type consists of a nozzle, a bellows and a pair of hinges connected to the nozzle. It can only absorb the angular displacement of a single plane. Two or three angular compensators should be combined to absorb displacement, and the hinges have the ability to withstand internal pressure and thrust. Effect: 1. Compensation for the axial, transverse and angular cold and hot deformation of absorption pipeline. 2. The expansion of the corrugated compensator facilitates the installation and disassembly of the valve pipeline. 3. Absorbing equipment vibration, reducing the impact of equipment vibration on pipelines. 4. Absorbing the deformation of pipeline caused by earthquake and subsidence.
