[0002] Gas sub-high pressure pipelines are an important part of urban gas supply. The opening and closing operation of their valves is of great significance to ensure the safety and reliability of gas transportation. The traditional valve operation method requires going down the well, and this device is needed at this time.

[0003] Based on the findings in the prior art, the traditional valve operation method requires a repair vehicle to arrive at the site, use a fan to replace the air in the valve well, wear a professional gas mask and hang a safety rope with a tripod to go down the well to switch the valve. The entire operation process takes nearly 1 hour. Going down the well is a confined space operation, and there are safety risks such as poisoning and suffocation. At the same time, operators need to wear professional gas masks, which are inconvenient to operate and easily lead to operating errors, resulting in large natural gas losses. If a gas leak occurs, the traditional operation method cannot close the valve in time, which will cause a large amount of natural gas loss. Utility Model Content
