Description

Technical Field

[0001] The utility model relates to a pipeline compensator technology, in particular to a detachable non-metallic compensator. Background Art

[0002] At present, in order to achieve the effects of corrosion resistance, high temperature resistance and wear resistance, the existing non-metallic compensators mainly set structural components such as flanges and transportation tie rod assemblies and insulation components on the pipeline. The setting of the above structures makes the on-site installation difficult. Therefore, a non-metallic compensator that is convenient for on-site assembly and replacement is needed. Content of the Utility Model

[0003] In order to solve the deficiencies of the above technologies, the utility model provides a detachable non-metallic compensator, which is arranged on a pipe body and includes a compensator main body sleeved on the pipe body and clamp assemblies arranged at both ends of the compensator main body. The clamp assemblies fix the compensator main body on the pipe body. The compensator main body includes heat preservation cotton, heat preservation blanket and loop belt. The heat preservation blanket is arranged close to the pipe body. The loop belt and the heat preservation blanket are connected end to end to form a heat preservation cavity, and the heat preservation cotton is filled in the heat preservation cavity.

[0004] In a further technical solution, the loop belt and the heat preservation blanket wrap the heat preservation cotton from above and below respectively. After the end of the heat preservation blanket is turned up, it covers the end of the loop belt and is fixedly connected with the loop belt.

[0005] In a further technical solution, a wire mesh is wrapped around the outer circle of the heat preservation cotton.

[0006] In a further technical solution, the shape of the clamp assembly is circular or rectangular.

[0007] In a further technical solution, the clamp assembly includes a plurality of clamps connected end to end. A connecting part is arranged at the end of the clamp assembly, and the connecting parts between adjacent clamps are locked by bolts and nuts.

[0008] Advantages of the Utility Model

[0009] 1. The heat preservation structure formed by the heat preservation blanket, heat preservation cotton and loop belt of the utility model has the characteristic of high temperature resistance and is suitable for the installation environment with small installation space;

[0010] 2. Since the non-metallic compensator is only used for low-pressure pipelines and the blind plate force between pipelines it bears is small, therefore, in the utility model, fasteners avoid the flanges, railing assemblies, etc. which are difficult to install in the prior art. The fastening assembly is replaced by a clamp assembly, and the fastening can fully meet the strength requirements. At the same time, the utility model requires fewer metal parts for installation and fixation, can effectively save costs, and can meet some occasions where only on-site assembly of non-metallic compensators is possible.

[0015] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0016] The present utility model provides a detachable non-metallic compensator, including a compensator main body as shown in Figure 1 the figure, and two groups of clamp assemblies 7. The compensator main body is sleeved on the pipe body and is arranged closely against the pipe body. The clamp assemblies 7 are arranged at both ends of the compensator main body to fix the compensator main body on the pipe body. The compensator main body includes heat preservation cotton 4, heat preservation blanket 1, and loop belt 2. The clamp assembly 7 includes a plurality of clamps 71 connected end to end. A connection part 6 is arranged at the end of the clamp assembly 7, and the connection parts 6 between adjacent clamps 71 are locked by bolts 72 and nuts 73.

[0017] Among them, the loop belt 2 and the heat preservation blanket 1 are connected end to end to form a heat preservation cavity 3, and the heat preservation cotton 4 is filled in the heat preservation cavity 3. The loop belt 2 and the heat preservation blanket 1 respectively wrap the heat preservation cotton 4 from above and below. The end of the heat preservation blanket 1 is turned up and covers the end of the loop belt 2 and is fixedly connected to the loop belt 2. The outer circle of the heat preservation cotton 4 is wrapped with a steel wire mesh 5.

[0018] During on-site installation, the compensator main body is sleeved into the pipe fitting. After finding the positions at both ends, the clamp assembly 7 is used to tighten along the track of the connection part 6 to complete the installation. For circular pipes, the circular clamp assembly 7 as shown in Figure 2 the figure is used, and for rectangular pipes, the rectangular clamp assembly 7 as shown in Figure 3 the figure is used.

[0019] The above implementation manners are not limitations on the present utility model, and the present utility model is not limited to the above examples either. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model also fall within the protection scope of the present utility model.
