Problems solved by technology

In the prior art, the tape is pasted on the port of the pipe, and then the protective gas (argon) tube is passed through the tape to pass the gas into the pipe. However, due to the stickiness of the tape itself, it is easy to dirty the pipe and it is not easy to Cleaning; In addition, because the pipe that feeds the shielding gas into the pipeline is far away from the shielding gas storage tank, it will take a certain amount of time to turn off the shielding gas when the welding is completed, which causes a lot of waste of shielding gas
[0003] In order to solve the above-mentioned problems of sticking tape on the pipe port, it is easy to dirty the pipe, it is not easy to clean, and the problem of wasting protective gas, the designer actively researched and innovated, and developed an automatic adjustable air plug group

Abstract

The invention discloses an automatic adjustable air plug group, which comprises an upper sealing air plug and a lower sealing air plug buckled on a pipeline port, wherein the upper sealing plug comprises an upper sealing cover and an air value assembly arranged on the upper sealing cover; when the upper sealing plug is buckled on the pipeline port, the air valve assembly and the pipeline are communicated with each other; and when the upper sealing plug is separated from the pipeline, the air valve assembly and the pipeline are in closed state. In the automatic adjustable air plug group, the upper sealing air plug and the lower sealing air plug are adopted, so that the problems of easiness in dirtying the pipeline and difficulty in cleaning caused by pasting an adhesive tape on the pipeline port are solved, the problem of easiness in wasting protecting gas is solved, and protective gas can be saved by about two thirds in practical application.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an automatic adjustable gas plug group. Background technique [0002] At present, in order to prevent the pipe wall from being oxidized when welding the interface between the pipes, it is necessary to pass the pipe wall protection gas into the pipe to prevent the pipe wall from being oxidized. In the prior art, the tape is pasted on the port of the pipe, and then the protective gas (argon) tube is passed through the tape to pass the gas into the pipe. However, due to the stickiness of the tape itself, it is easy to dirty the pipe and it is not easy to Clean up; In addition, because the pipe that feeds shielding gas in the pipeline is far away from the shielding gas storage tank, it will take a certain amount of time to close the shielding gas when welding is completed, which causes a lot of waste of shielding gas. [0003] In order to solve the above-mentioned problems...
