Claims

[Scope of utility model registration request]

In a large-mouth valve operating mechanism in which a servo motor and a weight are attached to an arm connected to a valve shaft, the mechanism is composed of an arm that holds the weight and an arm that is connected to the servo motor, and both arms are rotated on a single axis. The weight is connected by a pin, and the weight is configured to be able to rotate about the pin of the -axis as a fulcrum by an auxiliary operation mechanism, so that the closing operation torque of the inlet valve is maximized, and when the inlet valve is opened, A large-mouth valve characterized in that the position of the weight is moved so that the opening operation force of the servo motor is minimized.
