Anti-seismic replacement PE pipe

Abstract

The invention discloses an anti-seismic replacement PE pipe in the technical field of PE pipelines, the anti-seismic replacement PE pipe comprises an outer pipeline, a plurality of bending buffering mechanisms are arranged in an inner cavity of the outer pipeline, an inner pipeline is embedded among the bending buffering mechanisms, limiting connector mechanisms are arranged at the two ends of the outer pipeline, and the limiting connector mechanisms are arranged outside the inner pipeline in a sleeving mode. A plurality of inserting holes are formed in the top of the outer pipeline, and inner cavities of the inserting holes are connected with pressure hoops in a sealed mode. According to the anti-seismic and energy-absorbing device, abutting absorption of axial tension can be achieved through the multiple sets of non-Newtonian fluid bags, the situation that the using stability of the inner pipeline is affected by transverse impact is avoided, the anti-seismic and energy-absorbing processing capacity is effectively improved, and after seepage happens to the inner pipeline and the pressure of an inner cavity of the outer pipeline is increased, the anti-seismic and energy-absorbing effect is achieved. The pressure sensing film in the pressure hoop can be expanded and unfolded after the pressure is increased, and the water leakage pressurization position can be rapidly positioned outside the outer pipeline through the expanded and unfolded pressure sensing film.

Description

technical field [0001] The invention relates to the technical field of PE pipes, in particular to an anti-seismic replacement PE pipe. Background technique [0002] PE material generally refers to polyethylene. Polyethylene is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin, which are generally prepared into pipeline structures due to their good corrosion resistance; [0003] Some invention patents in the technical field of PE pipes are disclosed in the prior art, among which the invention patent with the application number CN110274096B discloses a PE pipe, including a pipe body and a rebound mechanism; a rebound mechanism is provided inside the pipe body; The rebound mechanism includes an extrusion chamber, an elastic layer, a spring and a pole; the extrusion chamber is uniformly set in the wall of the pipe body, and an elastic layer is arranged on the inner side of the extru...
