Description

Technical Field

[0001] This utility model relates to the field of pipe technology, and in particular to a multi-angle electrofusion elbow structure. Background Technology

[0002] Multi-angle electrofusion elbows are widely used in piping systems as pipe fittings. They are connectors manufactured using electrofusion technology that can change the direction of pipes. Electrofusion technology heats the pipe material using an electric heating element until it reaches a molten state, and then connects the pipes under external force. Traditional electrofusion elbows are typically designed and manufactured according to specific angle requirements, such as 45 degrees or 90 degrees. This fixed-angle design limits their flexible application in complex piping systems. Therefore, developing a multi-angle electrofusion elbow structure is of great significance. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-angle electrofusion elbow structure to overcome the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a multi-angle electrofusion elbow structure, including a bend, both ends of which are provided with connection ports. The connection mechanism includes a connecting pipe provided at one end of the bend. The connection pipe and the connection port of the bend are connected by a limiting mechanism. The connecting pipe and the bend are fixed together by a clamp.

[0006] Furthermore, the inside of the bent tube is provided with a resistance wire heating element, which is arranged along the inner wall of the bent tube and connected to an external power source through a wire.

[0007] Furthermore, the bending angle of both the bend and the connecting pipe is 60°.

[0008] Furthermore, the limiting mechanism includes a limiting groove disposed on the connecting pipe and a limiting block disposed on the bend pipe, wherein the limiting block can slide within the limiting groove.

[0009] Furthermore, the other end of the connecting pipe is provided with a connecting flange or a threaded joint.

[0010] Furthermore, a sealing gasket is provided on the connecting flange or threaded joint.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] Enhancing the flexibility and adaptability of piping systems: Multi-angle electrofusion elbows can provide connections at various angles to meet the needs of different piping systems. This flexibility allows for more flexible layout design during piping system setup, adapting to various complex installation environments. Simultaneously, it facilitates easier locating suitable connectors during piping system maintenance or replacement, reducing installation difficulty and time.

[0013] Enhanced connection strength and sealing performance: Multi-angle electrofusion elbows utilize electrofusion connection, heating the pipe material through an electrothermal element until it reaches a molten state, then achieving a seamless connection under external force. This connection method not only improves connection strength but also ensures a tight seal. Compared to traditional mechanical connections, electrofusion connections more effectively prevent leaks and seepage, thereby enhancing the safety and reliability of the piping system.

[0014] In summary, the multi-angle electrofusion elbow structure is beneficial for improving the flexibility and adaptability of pipeline systems, enhancing connection strength and sealing performance. This invention features a simple and stable structure, is suitable for multi-angle elbows, is suitable for mass production, reduces the manufacturing cost of unconventional elbows, and enhances the practicality of elbows during construction.
