1 dark rod valve when the steering wheel in the switch is connected with the valve stem is relatively fixed, it is a fixed point in the rotationthrough the valve stem to drive the valve flap upward and to complete the opening and closing of the gate. That the valve rod is threaded through the drive rod and the steering wheel to raise orlower the valve. That simple point is that the valve rod is attached to the valve stem moves up and down together, the steering wheel has a fixed point.
