Description

Technical Field

[0001] This utility model mainly relates to the field of corrugated pipe compensator technology, specifically to a corrugated pipe compensator with waterproof and heat-insulating functions. Background Technology

[0002] Bellows compensators are a type of compensating element that utilizes the effective expansion and contraction deformation of its working body, the bellows, to absorb dimensional changes in pipes, conduits, containers, etc., caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements of pipes, conduits, containers, etc. Bellows compensators have a wide range of applications in modern industry.

[0003] Because bellows compensators are commonly used for pipeline compensation, the waterproofing and insulation effects of currently available bellows compensators are not ideal. Bellows compensators use a central bellows section to compensate for internal deformation and displacement, and connect to the pipeline via flanges at both ends. A connecting pipe is installed between the bellows and the flanges to facilitate the connection. The bellows and connecting pipe are typically fixed by welding. However, because the bellows needs to adapt to the deformation inside the pipeline, frequent deformation can easily lead to loosening or cracking at the connection between the connecting pipe and the bellows. Once cracks appear, rainwater can easily seep in, affecting the safety of the internal wiring. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a corrugated pipe compensator with waterproof and heat-insulating functions to solve the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a corrugated pipe compensator with waterproof and heat-insulating functions, comprising a corrugated pipe compensator body, a first sleeve and a second sleeve correspondingly installed between the flanges on both sides of the corrugated pipe compensator body, the first sleeve and the second sleeve respectively being connected to the flanges on both sides, the first sleeve being slidably fitted onto the outside of the second sleeve, the corrugated pipe and connecting pipe of the corrugated pipe compensator body being located on the inside of the first sleeve and the second sleeve respectively; annular sleeves are also detachably installed around the outer periphery of the flanges on both sides of the corrugated pipe compensator body, and when the corrugated pipe compensator body is installed with the outer pipe, the annular sleeves are fitted around the outer flange at the end of the outer pipe.

[0009] Furthermore, the bellows compensator body includes a bellows, a connecting pipe, a flange, and multiple threaded tie rods. The bellows is connected to the flanges on both sides via the connecting pipes. Multiple ear plates are evenly arranged in a ring around the inner side of the flanges. The ear plates are provided with through holes for the threaded tie rods to pass through. The two ends of the threaded tie rods pass through the through holes on the ear plates on both sides of the flanges. Two nuts are threadedly installed on both sides of the threaded tie rods, and the two nuts are located on both sides of the ear plates.

[0010] Furthermore, the outer arc surfaces of the flanges on both sides of the bellows compensator body are machined with external threads, and the inner wall of one side of the annular sleeve is machined with internal threads that match the external threads. One side of the annular sleeve is threaded onto the flange, and the other side of the annular sleeve is fitted onto the outer side of the external flange at the end of the outer pipe.

[0011] Furthermore, the inner walls of both the first and second sleeves are fitted with annular heat insulation pads. The heat insulation pad on the inner side of the first sleeve is slidably fitted together with the outer wall of the second sleeve, and the first and second sleeves can slide and extend.

[0012] Furthermore, an annular heat insulation pad is fitted to the inner wall of the second sleeve, and an annular heat insulation pad is fitted to the outer wall of the first sleeve. The inner wall of the first sleeve and the outer wall of the second sleeve are fitted together and can slide and extend.

[0013] Furthermore, multiple first mounting holes are correspondingly opened on the flanges on both sides of the bellows compensator body, and multiple second mounting holes are correspondingly opened on the external flange at the end of the outer pipe. The number and position of the second mounting holes match those of the first mounting holes. The flange on the side of the bellows compensator body and the external flange at the end of the outer pipe are connected by bolts, and an annular sealing ring is also correspondingly installed between the flange on the side of the bellows compensator body and the external flange at the end of the outer pipe.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This utility model is reasonably designed. By installing sliding and telescopic first and second sleeves on the outside of the corrugated pipe and connecting pipe, and connecting and fixing them to the flanges respectively, it can effectively waterproof and dustproof the corrugated pipe and connecting pipe, and better avoid the problem of rainwater seepage due to loosening or cracks at the connection between the connecting pipe and the corrugated pipe. In addition, the heat insulation pads installed on the first and second sleeves can also effectively insulate the corrugated pipe and connecting pipe, preventing cracks at the connection due to extreme weather temperatures and extending their service life. Furthermore, the flanges on both sides of the corrugated pipe compensator are threaded with annular sleeves, which can shield the connection between the flange and the external flange on the outer pipe, further improving the waterproof effect.

[0017] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description
