Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically to a pipe connection anti-wear structure. Background Technology

[0002] In industrial production, piping systems often use flexible joints (such as rubber flexible joints) to compensate for displacement and reduce vibration and noise. In pipelines transporting abrasive materials, the material continuously impacts and rubs against the inner wall of the flexible joint as it flows through it. Because flexible joint materials are usually softer and less wear-resistant than metal pipes, they are easily worn through or torn, leading to media leakage. This requires frequent shutdowns for replacement, increasing maintenance costs and affecting the continuity of production.

[0003] Therefore, there is an urgent need for a pipe connection structure that can effectively protect flexible connections and extend their service life. Utility Model Content

[0004] The purpose of this utility model is to provide a wear-resistant structure for pipe connections, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connection anti-wear structure, including a discharge component and a receiving component used in conjunction. The discharge component includes an integrally connected main pipe and a sleeve. The sleeve gradually decreases in size from one end to the other, forming a trumpet shape, and the small end of the sleeve is fitted onto the outer circumference of the main pipe. The receiving component is fitted onto the discharge component.

[0006] Preferably, the large end of the sleeve extends outward to form a sleeve portion.

[0007] Preferably, the receiving component includes a second socket portion, a transition portion, and a third socket portion that are integrally connected in sequence, wherein the transition portion gradually decreases in size from one end closer to the second socket portion to one end closer to the third socket portion.

[0008] Preferably, the inner diameter of the third socket part is adapted to the outer diameter of the main pipe.

[0009] Preferably, the discharge component and the receiving component are made of any one of plastic, rubber or stainless steel.

[0010] Preferably, an annular cavity is formed between the first sleeve portion and the second sleeve portion to accommodate and protect the flexible pipe connection.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting up a trumpet-shaped sleeve and receiving component, ensures that when the material flows through the connection, it always comes into contact with the inner walls of the discharge and receiving components. The flexible pipe connection, protected in the outer annular cavity, completely avoids direct contact with the material, fundamentally solving the wear problem of the flexible connection and greatly extending its service life.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Please see Figures 1 to 3 One embodiment of this utility model is a pipe connection anti-wear structure, which includes a discharge part 1 and a receiving part 2.

[0017] The discharge component 1 is integrally formed from the main pipe 11 and the sleeve 12. The sleeve 12 is trumpet-shaped, with its small end fixedly sleeved on the outer periphery of the outlet end of the main pipe 11, and the large end of the sleeve 12 extends outward horizontally to form a sleeve part 13.

[0018] The receiving part 2 is integrally formed from the second socket part 21, the transition part 22 and the third socket part 23. The transition part 22 is also flared and is connected between the second socket part 21 and the third socket part 23. The inner diameter of the third socket part 23 matches the outer diameter of the main pipe 11, and the main pipe 11 can be inserted into the socket part 23.

[0019] During installation, firstly, sleeve part 13 and sleeve part 21 are fitted together to form a flexible pipe connection. Then, sleeve part 3 23 of receiving part 2 is connected and fixed to the discharge pipe. At this time, sleeve part 13 of discharge part 1 and sleeve part 21 of receiving part 2 are positioned opposite each other, forming an annular cavity 4 between them, and the flexible pipe connection is protected within this cavity.

[0020] Furthermore, both the sleeve 12 and the transition section 22 are funnel-shaped structures, and the annular cavity 4 formed by them has the ability to rebound and withstand impact, which can protect the main flow channel 11 inside from the outside to the inside.

[0021] In this embodiment, the discharge part 1 and the receiving part 2 are made of PTFE plastic material. PTFE plastic material has the advantages of strong corrosion resistance and high purity. At the same time, its excellent elastic deformation ability makes it easier to connect the first fitting part 13 and the second fitting part 21.

[0022] In this embodiment, the outer circumferential surface of the second sleeve 21 is elastically deformed and embedded into the inner wall of the first sleeve 13, and the second sleeve 21 and the first sleeve 13 are interference-fitted.

[0023] In other embodiments, a connecting pipe may be added, with the first sleeve 13 and the second sleeve 21 respectively sleeved to both ends of the connecting pipe, and the main pipe 11 passing through the inside of the connecting pipe.

[0024] In other embodiments, the discharge component 1 and the receiving component 2 may be made of rubber or stainless steel; the discharge component 1 and the receiving component 2 may also be made of other metal materials.

[0025] Working principle: First, the first sleeve 13 and the second sleeve 21 are fitted together. The material flows into the discharge part 1, then flows through the main pipe 11, then through the inner wall of the transition part 22 of the discharge part 2, and finally flows out from the third sleeve 23 to the discharge pipe. Throughout the process, the flow path of the material is restricted within the continuous and smooth channel formed by the inner walls of the receiving part 2 and the discharge part 1. The flexible pipe connection, protected in the annular cavity 4, is completely isolated from the material flow, thus avoiding any form of erosion and wear. The flexible pipe connection only needs to withstand the pressure, displacement, and vibration of the pipeline system, and its sealing and compensation functions can be performed normally.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
