Description

Technical Field

[0001] The invention relates to the technical field of equipment engineering, and in particular to an improved expansion joint structure. Background Art

[0002] An expansion joint is a flexible structure installed on a container shell or a pipe. Traditional rectangular metal expansion joints are generally composed of one or two groups of bellows. As a core component, the bellows absorbs and compensates for the dimensional changes or displacements of the pipe or equipment caused by temperature changes or mechanical vibrations through its elastic deformation ability. When the parameters of each group of bellows remain unchanged except for the number of waves, the more waves there are, the greater the circumferential membrane stress, circumferential bending stress, and deflection of the bellows. When large displacements need to be compensated, rectangular expansion joints will not be able to meet the displacement requirements due to the limited number of waves. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an improved expansion joint structure to solve one or more problems in the prior art.

[0004] To achieve the above object, the technical solution of the present invention is as follows: An improved expansion joint structure comprises a pipe body, wherein the pipe body is composed of at least one group of corrugated segments, wherein the corrugated segments are composed of a straight segment, a first arc segment and a second arc segment, and reinforcing components are evenly arranged between the corrugated segments.

[0005] Furthermore, the reinforcement assembly includes a reinforcement member, which is a T-shaped structure and is symmetrically arranged at both ends of the tube body.

[0006] Furthermore, the reinforcement comprises a first part and a second part, the first part is arranged to intersect the second part, and the second part is symmetrical with respect to the first part.

[0007] Furthermore, the first portion is arranged parallel to the straight section.

[0008] Furthermore, a portion of the first part is located outside the tube body, and a portion of the first part is located inside the tube body.

[0009] Furthermore, the second part is arranged inside the tube body.

[0010] Furthermore, the length of the first portion outside the tube body is greater than the length of the corrugated section protruding from the surface of the tube body.

[0011] Furthermore, the reinforcement assembly also includes a support member, which intersects the second part and is symmetrical with respect to the first part.

[0012] Furthermore, both ends of the support member are connected to the second part.

[0013] Furthermore, the support member is located inside the tube body.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The present invention provides a reinforcement assembly consisting of a reinforcement member and a support member, and separates a multi-wave corrugated pipe body with the reinforcement member to form a corrugated section composed of multiple single waves, and the number of corrugated sections of the expansion joint is not limited. At this time, the straight section of the corrugated section has a support that can fully withstand the pressure, and the circumferential membrane stress, circumferential bending stress and deflection are all zero. In addition, the setting of the support member also supports the reinforcement member, thereby further improving the strength. BRIEF DESCRIPTION OF THE DRAWINGS

In the present embodiment, a group of the corrugated segments is composed of one first arc segment 102, two straight segments 101 and two second arc segments 103. Reinforcement components 2 are evenly arranged between the corrugated segments. Preferably, the reinforcement components 2 and the corrugated segments are arranged at intervals in the present embodiment.

[0020] Further, the reinforcing assembly 2 includes a reinforcing member 201, which is a T-shaped structure and is symmetrically arranged at both ends of the tube body 1.
