| description | PROBLEM TO BE SOLVED: To provide a waterwheel inlet valve controller which can prevent abnormal water pressure, vibration or damage from being generated at a casing or a penstock in a waterwheel inlet valve with no side valve. SOLUTION: This controller is provided with limit switches 11, 12 which operate at a prescribed position of a waterwheel inlet valve 2 opened and closed by a motor 9, a switching means which is formed inside an electric circuit for driving the motor 9 and receives the signals of the limit switches 11, 12 to switch the driving speed of the motor 9, and a stopping means which stops the motor 9 for a prescribed period, formed at the switching means. |
