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

Embodiment 1

[0045] see Figure 1-2 , an electric bellows for air-contact self-coagulation repair, including a pipe body 1, the pipe body 1 includes a plurality of interconnected bamboo shoot-shaped protrusions 11, a concave groove is formed between two adjacent bamboo shoot-shaped protrusions 11, and the concave surface The groove is inlaid with an outer reinforcing layer 2, see Figure 7 , the outer reinforcement layer 2 is a porous structure, and the inner walls of multiple holes on the outer reinforcement layer 2 are fixedly connected with double capsules 21, the double capsules 21 are elastic porous structures, and the gaps are smaller than the particle diameter of the mixed powder, so that Under normal circumstances, the mixed powder inside it is not easy to leak. The double capsule 21 is a mixed powder filled with water-swellable particles and fluorescent powder. When subjected to bending force, the outer reinforcing layer will 2 is deformed, which drives the internal double capsul...

Abstract

The invention discloses an electric bellows for air-contact self-condensation repair, which belongs to the field of electric pipes. The electric bellows for air-contact self-condensation repair has a certain shock resistance and unloading force on the one hand through the setting of the air contact layer. It can effectively protect it from part of the extrusion force, and play a certain role in protecting the tip of the bamboo shoot-shaped bulge, effectively avoiding its rupture under force. On the other hand, when it is subjected to a large bending force, the gas The compression of the contact layer causes the gas to have a certain extrusion effect on the embedded extension piece, and the inner extension piece expands and deforms toward the side of the inner liquid storage ball, so that the folded part is stretched, so that the inner contact point It can be in contact with the inner liquid storage ball and puncture the inner liquid storage ball, so that the internal repair agent overflows. When the bamboo shoot-shaped protrusion is partially ruptured, it can flow out along the rupture in time, so as to realize the repair of the rupture or crack. Self-repairing, significantly reducing the occurrence of leakage caused by rupture.

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...
