Technical Field

[0001] The present invention relates to the technical field of valve opening and closing assistance, and in particular to a valve opening and closing assistance device. Background Art

[0002] At present, there are 98 valve wells in the apron oil supply network of Capital Airport, and each valve well has 1-3 valve switches. For a long time, the maintenance personnel of the apron equipment have to go down to the well and rely entirely on manual operation to maintain the valves.

[0003] There are many problems in relying solely on manual operation to open and close valves. First, daily maintenance of a valve requires about 80 turns to open it, and the valve needs to be opened and closed many times, which is time-consuming and labor-intensive. Second, in emergency situations, multiple people are required to operate, which is inefficient and affects the repair time. Third, the valve well space is small, and it is difficult for multiple people to operate, which poses potential operational risks.
