A memory alloy pipeline repair device and its application method

Abstract

The invention discloses a device for repairing a memory alloy pipeline, which comprises a pipeline to be repaired, a hole to be repaired is arranged on the pipeline to be repaired, a repairing device is provided at the right end of the pipeline to be repaired, the repairing device includes a fixing ring, and the The left side of the fixed ring is fixedly connected with the right end of the pipeline to be repaired, the inner wall of the fixed ring is fixedly connected with shell one, the shell one is placed in the pipeline to be repaired, and the inner wall of the shell one is slidably connected with shell two, so The right side of the second shell is fixedly connected with a transmission rod, the surface of the transmission rod runs through the shell one and is slidably connected with the first shell, and the right end of the transmission rod is fixedly connected with a push-pull ring. The present invention, through the cooperative use of the above-mentioned structures, solves the problems of not being easy to stick to the pipe wall, falling off, aging, loosening and causing pipe leakage during the actual use process due to the traditional repair method. Inconvenience to use.

Description

technical field [0001] The invention relates to the technical field of pipeline repair equipment, in particular to a memory alloy pipeline repair device. Background technique [0002] Pipeline repair refers to the use of various technologies to restore the normal function of the damaged or leaking pipeline. The repair includes two technologies: external anti-corrosion layer repair and internal repair; for example, when holes appear on the inner wall of the pipeline, it is necessary to repair Carry out spot repair; traditional repair methods include resin curing method and double expansion ring method. Inconvenient, for this reason we propose a device utilizing memory alloy pipeline repair. Contents of the invention [0003] The purpose of the present invention is to provide a memory alloy pipeline repair device, which has the advantages of high corrosion resistance, aging resistance, tight sealing, strong external expansion, and adaptability to various inner diameters of ...
