Patent abstract
A volumetric metering smart valve shuts down automatically when a certain amount of liquid has passed through the valve. This valve has a water wheel which is rotated by the liquid and which drives a disc via a gear train. If the flowing amount exceeds a preset limit, the disc operates a ratchet and spring acting on a column in a closing direction to shut down the valve.
