Efficient cooling discharge valve

An efficient cooling discharge valve comprises a valve body (1), a motor (4), a speed reducer (5), a compressor (10), an evaporation chamber (11) and a heat exchange chamber (12). The efficient cooling discharge valve is characterized in that flanges (2) are arranged on both the upper side and the lower side of the valve body (1), the motor (4) and the speed reducer (15) are connected together through a coupler (8), a transmission gear (9) on the speed reducer (5) is in gear connection with a discharge gear (7) on the valve body (1), the compressor (10) is connected with the heat exchange chamber (12) which is communicated with a spindle (6) on the valve body (1), and the compressor (10) is connected with the spindle (6). The efficient cooling discharge valve is connected with a cooling device, the working temperature of the efficient cooling discharge valve can be effectively reduced, the speed reducer (5) is in gear transmission with the valve body (1), power output is stable, and slipping does not easily o
