An embodiment of the invention discloses a ball valve with a driving motor and metering equipment, relates to the technical field of valves, and aims to simplify a structure determining that a ball body rotates in place. The ball valve comprises a valve body and a motor, and the motor is arranged on the outer side of the valve body; a ball body is arranged in the valve body, the ball body is connected with a first end of a valve rod, a second end of the valve rod is located outside the valve body and connected with a sector gear, and the sector gear is meshed with a driving gear; a speed reducing mechanism is connected between the motor and the driving gear; a reset mechanism of the sector gear is arranged on the outer side of the valve body; and the motor rotates, the speed reducing mechanism drives the driving gear to rotate, after the driving gear drives the sector gear to rotate by a preset stroke, teeth on the sector gear are disengaged from teeth on the driving gear, the reset mechanism enables the sect
