AI Technical Summary
Traditional electric fusion pipe fittings are prone to gaps during connection, resulting in loose connections, uneven interfaces after installation, and may cause cold welding, smoking or spraying, and are prone to falling off or water seepage under pressure.
An electric fusion rubber ring double-seal integrated pipe fitting was designed, which includes a gland, a heating wire and a positioning sealing ring. The heating wire is located on the inner wall of the pipe mouth, and the sealing ring is embedded in the pipe mouth and close to the outlet. An installation groove is provided on the outer wall, and the gland is located in the groove. An electrode access port is provided outside the heating wire. The connection is achieved by heating with the heating wire, and the stability of the connection is ensured by the combination of the sealing ring and the gland.
It improves the firmness and installation speed of pipe connections, ensures that the interfaces are horizontal and vertical, avoids cold welding, smoke and water seepage, and enhances stability under pressure.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipe fitting structures, in particular to an electric fusion rubber ring double-sealed integrated pipe fitting. Background Art
[0002] Traditional electric fusion pipe fittings often have gaps when connected, the connection is not firm enough, and it is impossible to ensure that the interface is horizontal and vertical after installation. After welding, there will be cold welds, smoke or spraying, and the interface will fall off or leak under pressure. Utility Model Content
[0003] Based on this, the utility model is created to solve the above technical problems.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electric fusion rubber ring double-sealed integrated pipe fitting, mainly composed of a gland, a heating wire, a positioning sealing ring, and a pipe mouth, the heating wire is located on the inner wall of the pipe mouth, the sealing ring is embedded in the pipe mouth, and is closer to the outlet than the heating wire, and an installation groove is provided on the outer wall of the pipe mouth, and the gland is located in the installation groove.
[0005] Furthermore, the heating wire peripheral is connected to an electrode access port.
[0006] Furthermore, the heating wire has 7 turns.
[0007] Furthermore, the sealing ring is elastic.
[0008] In summary, the present invention has the following beneficial effects:
[0009] The utility model heats the openings by arranging electric heating wires at a pair of openings, thereby plasticizing the openings and connecting the pipe fittings to the HDPE pipe. At the same time, the sealing ring and the pressure cover combination arranged at the socket ensure that the connection is horizontal and vertical, thereby improving the installation speed and not relying on technology.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0014] The following describes an embodiment of the present invention based on its overall structure.
[0015] An electric fusion rubber ring double seal integrated pipe fitting, such as Figure 1-2 As shown, a dual-seal integrated pipe fitting with an electric fusion rubber ring is primarily composed of a gland 5, a heating wire 4, a positioning seal ring 3, and a pipe orifice. The heating wire 4 is located on the inner wall of the pipe orifice, and the positioning seal ring 3 is embedded in the pipe orifice. The seal ring 3 performs positioning and sealing functions, facilitating the connection between the two pipe fittings. Its elasticity facilitates the fixation and management of the fittings before welding. The seal ring 3 is closer to the outlet than the heating wire 4, providing initial positioning before the secondary electric fusion welding is achieved through the heating wire 4. A mounting groove 50 is provided on the outer wall of the pipe orifice, and the gland 5 is located in the mounting groove 50, facilitating the fixing of the seal ring after connection. The heating wire 4 is externally connected to an electrode access port to facilitate heating. The heating wire 4 has seven turns, which is more practical.
[0016] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
