Device for repairing pipeline through memory alloy and using method thereof

Abstract

The invention discloses a device for repairing a pipeline through memory alloy. The device comprises a to-be-repaired pipeline body, a to-be-repaired hole is formed in the to-be-repaired pipeline body, a repairing device is arranged at the right end of the to-be-repaired pipeline body, the repairing device comprises a fixing ring, the left side of the fixing ring is fixedly connected with the right end of the to-be-repaired pipeline body, the inner wall of the fixing ring is fixedly connected with a first shell, the first shell is arranged in the to-be-repaired pipeline body, the inner wall ofthe first shell is slidably connected with a second shell, the right side of the second shell is fixedly connected with a transmission rod, the surface of the transmission rod penetrates through thefirst shell and is slidably connected with the first shell, and the right end of the transmission rod is fixedly connected with a push-pull ring. According to the device for repairing the pipeline through the memory alloy and the using method thereof, through cooperative use of the structures, and the problems that in the actual use process, due to the fact that a traditional repairing device is not prone to being tightly adhered to the pipe wall in the use process, falling off, aging and loosening are prone to happening, pipeline leakage is caused, and inconvenience is brought to use are solved.

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 ...
