The utility model discloses an automatic drainage structure for a volute of a steam compressor, which can timely drain accumulated water in the volute. Comprising a volute, a drainage tank and an electromagnetic valve, the pressure in a cavity of the volute is positive pressure, a U-shaped pipeline is connected between the volute and the drainage tank, the U-shaped pipeline comprises a U-shaped section, an L-shaped section located at the upstream end of the U-shaped section and an r-shaped section located at the downstream end of the U-shaped section, the upstream end of the L-shaped section is connected to the bottom of the volute, and the r-shaped section is connected to the bottom of the drainage tank. The downstream end of the r-shaped section is connected to the top end of the drainage tank, the flat part of the L-shaped section is lower than the flat part of the r-shaped section, so that the upstream end of the U-shaped section is lower than the downstream end of the U-shaped section, the bottom end of
