The lubricating oil can contact the worm 4 and drive the first motor 7 to work. The lubricating brush 18 can then lubricate the contact end of the worm 4 and the worm gear 5 to improve its wear resistance. After lubrication, rotate the threaded rod 16 in the opposite direction, and the lubricating brush 18 is away from the worm 4. When heat dissipation is needed, drive the second motor 9, and the second motor 9 drives the fan 10 to rotate. The fan 10 can discharge heat from the working box 6, and the indicator needle 13 rotates with the worm gear 5. The distance between the indicator needle 13 and the indicator block 14 can be observed to judge the opening and closing degree of the valve.
