Protection device for water supply system in e.g. house, has comparator generating triggering signal reacting on actuating drives for valves in terms of stoppage in increased output for predefined integration time over threshold value

摘要

The device (16) has a flow rate meter (13) formed such that a unit of time is decreased by a flow rate that corresponds to signals of the meter. A comparator (27) releases a reset signal (28) that resets an integration device (24) when the integration device does not meet a threshold value through an integrated output for a predefined integration time. The comparator generates a triggering signal reacting on actuating drives (20, 21) for an inlet valve (14) and/or an outlet valve (15) in terms of stoppage in the increased output for the predefined integration time over the threshold value.
