Multi-layer plastic tube structure with wear resistance and long service life

Abstract

The invention provides a multi-layer plastic tube structure with the wear resistance and the long service life. The multi-layer plastic tube structure comprises an inner tube, a plurality of rivet seats, auxiliary connecting rings, an intermediate tube, a plurality of rivet T-grooves, splicing ring grooves, clamping rings, connecting through holes, insulating leakage detection rings, rivet sleeves, metal rings and an outer sleeve tube. The plurality of rivet seats are integrally arranged on the outer portion of the inner tube. The rivet seats are parallel in the axial direction and are arrayed in four sets of each column. The outer end of the intermediate tube is provided with the rivet T-grooves. The rivet T-grooves are parallel in the axial direction and are arrayed in four sets of each column. The water leakage detection function is added to a plastic tube through the metal rings and the insulating leakage detection rings. The positions and spaces between the metal rings are fixed, and the metal rings communicate with rivets. The multi-layer plastic tube structure can be used normally after pen meter detection. During inspection, a multimeter can be directly used for detecting the visible rivets in the outer sleeve tube to judge whether water leakage occurs through resistance detection. The multi-layer plastic tube structure is convenient to use, good in detection effect and beneficial to maintenance and application.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, and more specifically relates to a multi-layer plastic pipe structure with wear resistance and high service life. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are extruded in the pipe making machine by the "plastic" method. They are mainly used for housing construction. Water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation, etc. [0003] Based on the above, most of the currently used plastic pipes have an integrated structure, and the external stress relief will be transmitted to the internal deformation, etc., and it is inconvenient to replace the equipment through the uniformly manufactured pipe structure, which is not conducive to saving costs. The p...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the present invention provides a multi-layer plastic pipe structure with wear resistance and high service life. Through the improvement of structure and function, it solves the problem that most of the plastic pipes currently used are integrated structures, and the stress is relieved externally. It will convey the internal deformation and other situations, and it is inconvenient to replace the equipment through the uniformly manufactured pipe structure, which is not conducive to saving costs, and the general plastic pipe does not have the problem of auxiliary detection of water leakage
