Problems solved by technology

[0003] However, in the existing technology, when sealing the gas pipeline by welding, it takes a certain amount of time due to the complicated operation of the sealing device, so there is a risk of partial gas leakage at the construction site
In addition, during the use of the existing plugging device, due to the unstable working state of the plugging device, when the plugging device is installed on the gas pipe, leakage often occurs, which greatly increases the construction site. job risk

Abstract

The invention discloses a gas pipe plugging device, and relates to the field of gas engineering. The gas pipe plugging device comprises a power device, an elastic mat and a pressing plate; the power device comprises a cylinder body, a cylinder cover, a piston and a piston rod; a cavity is formed in the cylinder body which has a first end face and a second end face, and the piston rod has a first end and a second end; the piston is fixedly connected with the piston rod, and the piston rod penetrates the cylinder body; and the elastic mat is arranged between the pressing plate and the first end face. The gas pipe plugging device is simple in structure and convenient to use, and the gas pipe plugging device can be in butt joint with a gas pipe rapidly; and in addition, the gas pipe plugging device can be tightly attached to the inner wall of the gas pipe through the power device, the plugging effect is good, and leakage can be effectively prevented. Based on the above gas pipe plugging device, a plugging method is further provided.

Description

technical field [0001] The invention relates to the field of gas engineering, in particular to a gas pipe plugging device and a plugging method. Background technique [0002] During the repair or maintenance of the gas pipeline, the entire section of the gas pipeline needs to be shut down and vented due to welding construction. After the pressure in the pipeline is zero, due to the large diameter of the pipeline, the length of the pipeline, and the large height difference, there may still be residual gas in the pipeline. accidents caused by explosions. Therefore, during the whole process of maintaining the gas pipeline, the gas pipeline needs to be blocked and hot-fire welded to prevent gas leakage and explosion in the gas pipeline, and at the same time ensure the safety of the entire maintenance construction site. [0003] However, in the existing technology, when sealing the gas pipeline by welding, due to the complicated operation of the sealing device, it takes a certa...
