Valve operating handle

Abstract

The present article is for opening and closing a valve connected to an underground pipeline. As shown in the reference perspective view, the valve operating handle includes a horizontally long gripping portion and a shaft portion extending downward from the longitudinal center of the gripping portion. When opening and closing a valve, an operator holding the gripping portion rotates the valve operating handle around the shaft portion as a rotation axis. As shown in the reference exploded front view, a housing portion capable of housing a gyro sensor that acquires information about the rotation during operation of the valve operating handle is provided on a side of the shaft portion. A connecting portion is provided at the lower end of the shaft portion to which a torque sensor that acquires information about the torque during operation of the valve operating handle is connected. A valve-side shaft portion that is a member that engages with the valve is connected to the lower end of the torque sensor. The valve operating handle is configured by integrating (unitizing) a housing portion and a connecting portion that are arranged close to each other. A cover that covers the gyro sensor and the torque sensor can be attached to the valve operating handle.
