[0016] This utility model provides a pressurized discharge valve for a refueling truck filter, including a discharge pipeline. The discharge pipeline includes an oil pump 1, a PCV valve 2, and a filter 3. The PCV valve 2 is connected in parallel to a first control circuit and a second control circuit. The first control circuit includes a Dedemann control handle 4 for mechanical manual control. The second control circuit includes an Apollo ball valve handle 5 connected to the PCV valve 2 and a proximity switch 6 located on one side of the Apollo ball valve handle 5. The proximity switch 6 is electrically connected to the PCV valve 2 and can control the opening and closing of the PCV valve 2, satisfying the dual requirements of safety and ease of operation of the PCV valve 2.

[0017] In one embodiment, the upper end of the Apollo ball valve handle 5 is provided with a mounting base 7 for fixed installation with the discharge pipeline, an adjusting screw 8 on the mounting base 7, and a clamping seat 9 on the other end of the adjusting screw 8. The proximity switch 6 is adjustablely mounted on the clamping seat 9. The distance between the proximity switch 6 and the Apollo ball valve handle 5 is adjusted by the adjusting screw 8. It is highly practical and can adjust the position of the proximity switch 6 according to the actual situation to achieve precise control of the PCV valve 2. The proximity switch 6 is simple to install and has strong stability.

[0018] In one embodiment, the clamping base 9 consists of a first semi-circular arc-shaped clamp 10 fixed at one end on the mounting base 7, a second semi-circular arc-shaped clamp 11 opposite to the first semi-circular arc-shaped clamp 10, and an adjusting screw 12 connecting the first semi-circular arc-shaped clamp 10 and the second semi-circular arc-shaped clamp 11. The proximity switch 6 is installed by adjusting the screw 12.
