Description

Technical Field

[0001] The present invention relates to a segmented resistance wire joint for reinforced polyethylene electric fusion pipe fittings and an installation method thereof, and relates to a resistance wire joint and an installation method thereof used in the processing of reinforced polyethylene electric fusion pipe fittings, and belongs to the technical field of water supply and drainage, and particularly relates to a resistance wire joint that is pre-embedded with a hot-melt positioning sleeve in a joint installation hole, and the positioning block after jacking supports the inner wall of the joint installation hole, further fixes the positioning sleeve, and then fixes the resistance wire connection column to the positioning sleeve and the resistance wire through a connector. It can effectively prevent the joint from loosening and improve the connection stability with the resistance wire. Background Art

[0002] The pipe is usually made of PE material, which has the advantage of strong corrosion resistance, but its rigidity and strength are always important issues faced by R&D personnel. At present, the usual way to solve the material problem of the pipe is to start from material research and development, which has a long R&D cycle and high comprehensive cost.

[0003] In order to improve the above problems, the applicant filed a Chinese utility model patent application with publication number CN210153353U and patent name "Wire Wrapped Tube". The wrapped tube improves the structure of the row tube based on the physical level, including: an inner tube extruded by the first hot melt extrusion, an outer tube extruded by the second hot melt extrusion, and a steel wire layer sandwiched between the inner tube and the outer tube. The rigidity and strength of the tube body are enhanced by internal reinforcement ribs, so that the tube body is not easy to deform along the axial direction, greatly reducing the deflection of the tube body along the axial direction, and also has better shear resistance.

[0004] In actual use of pipes, multiple wire wrapped pipes need to be laid end to end in a groove to meet the drainage distance requirements. However, wire wrapped pipes cannot be directly hot-melt welded because of the steel wire wrapped inside the pipe wall. Therefore, polyethylene expansion hot-melt connection, polyethylene electric fusion pipe connection or rubber sealing ring connection are required for end to end connection. However, in the above connection methods, the connection part is made of pure polyethylene material and has a low pressure bearing capacity. The pressure bearing capacity of the connected wire wrapped pipe is lower than the pressure bearing capacity of the wire wrapped pipe itself. If the pressure bearing capacity of the wire wrapped pipe itself is used for water supply and drainage, it is easy to cause the connection to be subjected to excessive pressure and rupture. If the pressure bearing capacity of the connection is used for water supply and drainage, it will cause a waste of drainage capacity of a large section of wire wrapped pipe.

[0005] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A Reinforced Polyethylene Electric Fusion Pipe Fitting and Its Processing Method". The invention uses a cutting knife to open a spiral groove on the inner wall of the reinforced polyethylene pipe section, and at the same time buries the resistance wire in the groove, and buries the resistance wire by extrusion to form a reinforced polyethylene electric fusion pipe fitting. By connecting multiple steel wire winding pipes through the reinforced polyethylene electric fusion pipe fitting, the pressure bearing capacity of the connection can be effectively improved to keep it consistent with the steel wire winding pipe. After the wire is buried, the resistance wire joint needs to be inserted into the joint installation hole and connected to the resistance wire. The resistance wire joint and the joint installation hole are non-fixed connections. In the process of transporting it from the workshop to the site, the reinforced polyethylene electric fusion pipe fitting is easily vibrated or impacted due to bumps, causing the resistance wire joint to loosen or even fall off, resulting in poor contact between the resistance wire and the resistance wire joint, unstable current, uneven heating, and affecting the quality of the hot melt connection. Summary of the invention

[0006] In order to improve the above situation, the present invention provides a reinforced polyethylene electric fusion pipe segmented resistance wire joint and its installation method, which provides a resistance wire joint that is connected to the resistance wire by hot-melting a pre-embedded positioning sleeve filled with polyethylene raw materials, supporting the inner wall of the joint installation hole with a jacked positioning block, further fixing the positioning sleeve, and then fixing the resistance wire connecting column on the positioning sleeve and the resistance wire through a connector. It can effectively prevent the joint from loosening and improve the connection stability with the resistance wire.
