Technical Field

[0001] The utility model relates to the field of natural gas extraction and transportation, in particular to a valve booster tool. Background Art

[0002] During the natural gas transportation process, various valves are opened or closed according to production needs. When operating the valve, due to the pressure of the medium inside the valve, the structure and size of the valve, the valve not being operated for a long time, and inadequate maintenance, it will be difficult to turn the valve operating disk and the valve will not be easy to open or close. Especially for high-pressure valves, when operating the valve, the force is applied on one side, and it is often very difficult to open or close the valve. Therefore, it is usually necessary to use an F wrench to assist in opening or closing the valve.

[0003] However, due to the complex process flow of the gas transmission and distribution station, the wide variety of valves in the station, and the presence of a large number of equipment skids, when opening and closing the valves, the F wrench has a single force point, which can easily cause damage to the valve operating disk. In addition, the F wrench has a fixed pitch and cannot be adapted to all valves in the gas transmission and distribution station. Failure to operate the valves in a timely manner will cause immeasurable production losses and safety accidents.

[0004] Therefore, there is an urgent need for a technical solution to solve the technical problem that the existing F wrench cannot adapt to the use of different types of valves in gas transmission and distribution stations. Utility Model Content
