Description

Technical Field

[0001] The utility model belongs to the field of pipe compensators, and in particular relates to a rubber composite flexible compensator. Background Art

[0002] A compensator is a flexible structure installed on a container shell or pipeline to compensate for the additional stress caused by temperature difference and mechanical vibration. It absorbs the dimensional changes of pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or compensates for the axial, lateral and angular displacement of pipelines, ducts, containers, etc. It has the advantages of reliable operation, good performance and compact structure, and has been widely used in chemical industry, metallurgy, nuclear power plants and other departments.

[0003] The existing flexible rubber used at the inlet and outlet of the power plant furnace slurry circulation pump has insufficient axial compensation, insufficient rubber ball thickness, and low expansion and contraction rate. Long-term contact with the slurry will increase the hardness of the rubber, cause aging, corrosion, and severe wear, resulting in frequent leakage, increasing the workload of maintenance personnel, not only causing environmental pollution but also reducing the level of safe and civilized production on site. Summary of the Invention

[0004] The purpose of this utility model is to provide a rubber composite flexible compensator with large compensation amount, sufficient rubber ball thickness, and resistance to aging, corrosion and wear.

[0007] The compensator body comprises a butyl rubber inner layer, a fluororubber middle layer and a chloroprene rubber outer layer.

[0008] The compensator body further comprises an inner fiber layer arranged on the inner layer of butyl rubber, and an outer fiber layer arranged on the outer layer of chloroprene rubber, and the fiber strands of the inner fiber layer and the outer fiber layer are no less than 18 layers.

[0018] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] See Figure 1 The present application provides a rubber composite flexible compensator with a large compensation capacity, a rubber sphere of sufficient thickness, and resistance to aging, corrosion, and wear. The compensator comprises a compensator body 1, lugs 2, a tie rod 3, a backplate flange 4, and a rubber sphere 5. A backplate flange 4 is provided at each end of the compensator body 1. The lugs 2 and the outer sides of the backplate flange 4 are fixedly connected. The tie rod 3 is fixedly connected to the two lugs 2 via nuts. A set of through holes is provided on each of the compensator body 1 and the backplate flange 4, and the two sets of through holes are arranged in correspondence. After flanging, the compensator body 1 is connected to the backplate flange 4 via bolts and the two sets of through holes, and is finally fixedly mounted on a pipeline or container.

[0020] The material of the back plate flange 4 is 2205 stainless steel, which can further improve the service life of the rubber composite flexible compensator.

[0021] The thickness of the flange of the compensator body 1 is not less than 35 mm, and the thickness of the rubber ball 5 is not less than 35 mm. A polytetrafluoroethylene inner sleeve is also provided inside the compensator body 1.

[0022] The compensator body 1 comprises a butyl rubber inner layer, a fluororubber middle layer, and a chloroprene rubber outer layer. The fluororubber middle layer and butyl rubber inner layer offer strong wear resistance, corrosion resistance, and acid and alkali resistance. The chloroprene rubber outer layer offers strong UV protection and an abrasion resistance rating of 230 or higher. Fluororubber, butyl rubber, and chloroprene rubber account for no less than 56% of the compensator body 1.

[0023] The compensator body 1 also includes an inner fiber layer arranged on the inner layer of butyl rubber, and an outer fiber layer arranged on the outer layer of chloroprene rubber. The inner fiber layer and the outer fiber layer have no less than 18 layers of fiber hair to enhance the pressure resistance of the compensator body 1.

[0024] In summary, the utility model enhances the wear resistance, corrosion resistance, and aging resistance of the rubber body and increases the axial compensation amount to 30 mm by using a multi-layer composite rubber and increasing the thickness, thereby greatly improving the reliability of the operating system, reducing the workload of maintenance personnel, and avoiding environmental pollution.
