Air contact type self-condensation repaired electric corrugated pipe

Abstract

The invention discloses an air contact type self-coagulation repair electric power corrugated pipe, belongs to the field of electric power pipes, and provides the air contact type self-coagulation repair electric power corrugated pipe with the advantages that through the arrangement of an air contact layer, on one hand, a certain anti-seismic force unloading effect is realized, and the partial extrusion force can be effectively protected; on the other hand, when the bamboo-shoot-shaped convex joints are subjected to large bending force, the air contact layer is extruded, so that the embedded extending pieces are extruded to a certain extent, the sides, facing the inner liquid storage ball, of the embedded extending pieces expand and deform, and the folded parts of the embedded extending pieces are unfolded, so that the bamboo-shoot-shaped convex joints are prevented from being broken. The inner contact pricking point can make contact with the inner liquid storage ball and prick the inner liquid storage ball, a repairing agent in the inner liquid storage ball overflows, and when the bamboo-shoot-shaped convex joint is locally broken, the repairing agent can flow out along the brokenposition in time, so that self-repairing of the broken position or the cracked position is achieved, and the situation of electric leakage caused by breaking is remarkably reduced.

Description

technical field [0001] The invention relates to the field of power tubes, in particular to a gas-contact self-condensation repaired power bellows. Background technique [0002] The power pipe is a product made of PE (modified polyethylene) for hot-dipping or epoxy resin for internal and external coating, and has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and will not cause electrical corrosion. Low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent damage to plant roots and soil environmental stress. [0003] The power tube has the following characteristics: [0004] Light weight: the density of CPVC is 1350-1500KG / M3, the weight is generally 1 / 10 of similar pressure pipes and 1 / 6 of steel pipes, and the transportation and installation are convenient; [0005] Convenient construction and significant economic benefits: CPV...

Problems solved by technology

[0009] In the occasion where the bending resistance of the power tube is high, the power tube is usually set in a corrugated shape to improve its bending resistance. However, when the corrugated power tube is subjected to a large bending force, it will deform and sag. and the protruding parts will be subject to concentrated and large extrusion force, resulting in accidental damage to the two places, and there are certain safety hazards
