PURPOSE: An electric valve unit for garbage transfer pipes equipped with a worm gear is provided to improve garbage transfer efficiency by opening and closing the pipes using an electric valve disc which travels in the transfer pipes. CONSTITUTION: A valve disc(10) travels a traveling section on an inlet pipe(1) and a transfer pipe(3) while revolving so that the pipes are opened or closed. A case(20) covers the traveling section and houses a rotary shaft and the valve disc. A worm gear(60) links an electric actuator(70) with the rotary shaft and rotates the rotary shaft by reducing the rotation speed of the electric actuator. |
