[0002] According to the provisions of MH / T6020-2012 "Civil Aviation Fuel Quality Control and Operation Procedures" 13.1.3, for jet fuel ground wells that have not been used for 3 months, all fuel in the branch pipe should be flushed and discharged before use, and a sample should be taken for appearance inspection before use. Currently, all transport airports with airport pipeline networks have 3-month non-use fueling plugs, and all have the need for discharging oil inspection.

[0003] However, the existing discharge method uses a pipeline refueling truck connected to a tank-type refueling truck, which requires at least two experienced aircraft refueling personnel and two aircraft refueling trucks to complete the operation, which occupies a large number of operating personnel, and some maintenance personnel do not have the ability to refuel aircraft, which poses a certain safety hazard. At the same time, the use of more refueling equipment increases the cost of work, and too many devices also increase the operation space, making it more difficult to obtain permission from the airport side for discharge operation. Therefore, in order to solve the above problems, a special connector for flushing and discharging a ground well is proposed. SUMMARY

This allows for better compression of the inner wall of the well, thereby effectively improving the stability of the well joint during use and enhancing its practicality. Attached Figure Description
