Problems solved by technology

At present, there are mainly three connection methods for PE pipes: hot-melt pipe welding, butt welding of hot-melt pipe fittings, and hot-melt socket welding. Steel mesh skeleton plastic composite pipes are mainly welded by electric hot-melt pipe fittings. At present, this connection method is widely used. However, the cost of pipe fittings is too high, and this electric fusion connection method has several disadvantages: 1. It is inconvenient to install, and it is difficult to find the power supply on the construction site; 2. It is inconvenient to maintain, and it is difficult to ensure the welding quality during welding. This connection cannot be used
In view of the above characteristics, although many plastic pipe manufacturers and plastic pipe users have conducted a lot of research, they hope to develop a plastic pipe connection with low cost, good quality, convenient installation and connection, safer and more reliable connection method. but failed to achieve satisfactory results.

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0026] A new type of connection method for plastic composite pipelines with steel mesh skeletons. The inner and outer outer iron castings and flexible quick connectors are used as the pipeline connectors. Push one end of the inner sleeve iron casting 1 into the port of the pipe 5, then put the pipe end with the inner and outer sleeve iron castings in the shrinking machine to squeeze and seal the mouth, and the other end of the inner sleeve iron casting 1 protrudes from the Outside the port of the pipe 5, use the flexible quick joint 2 to fasten and connect the two inner sleeve cast iron parts 1 protruding from the pipe port. A rubber sealing ring 3 is installed inside the flexible quick joint, and the flexible joint is contracted by the screw 6 and the nut. The quick connector squeezes a...

Abstract

The invention discloses a novel connection mode for steel mesh skeleton plastic compound pipelines. By adopting two inner sleeve iron castings, two outer sleeve iron castings and flexible quick couplings to serve as pipeline connecting pieces, firstly, the two outer sleeve iron castings are sheathed onto the outer pipe walls of the ports of the pipelines; then, one ends of the two inner sleeve iron castings are jacked into the ports of the pipelines by adopting a pipe jacking machine; then, the ports of the pipelines, which are provided with the two inner sleeve iron castings and the two outer sleeve iron castings, are put in a shrink machine to be extruded, shrunk, sealed and fixed; the other ends of the two inner sleeve iron castings extend out of the ports of the pipelines; the two inner sleeve iron castings extending out of the ports of the pipelines are connected together in the manner of clamping by using the flexible quick couplings; rubber seal rings are respectively arranged in the flexible quick couplings; and the flexible quick couplings are shrunk by screws to extrude the rubber seal rings to deform to seal and fix the two inner sleeve iron castings. The novel connection mode for the steel mesh skeleton plastic compound pipelines has the advantages that the method is advanced and the structure is simple. The produced compound pipes are safer and more reliable in seal and installation structure. Installation materials, such as a welding machine, are not needed, thereby, the installation cost is lower, and the pipeline installation efficiency is greatly increased.

Description

technical field [0001] The invention relates to a new connection mode of steel mesh skeleton plastic composite pipeline. Background technique [0002] Steel mesh skeleton polyethylene composite pipe is a new type of high-tech and environmentally friendly chemical pipe that has emerged in China in the past ten years. It is a network structure formed by high-strength copper-plated steel wire winding and weaving left and right as the skeleton, high-density polyethylene as the base material (polyethylene is a special material for PE100 pipelines), and modified polyethylene---adhesive resin, It is a new generation of chemical building materials with pressure resistance, internal and external anti-corrosion formed by continuous and step-by-step extrusion compounding on the production line. The product specification is φ63~φ630mm, widely used in municipal water supply and drainage, petrochemical, electric power, coal and mining industries. [0003] At present, there are many kind...
