ABSTRACT:
An automatic shut-off valve arrangement for a fire sprinkler system includes a set of auxiliary pipe fittings interconnected between the water distribution pipes and the sprinkler heads. Each fitting houses a multi-vane paddle wheel rotatably mounted under an eccentric valve opening normally unobstructed by a movable valve member, and the paddle wheel axle is connected by a gear train to an actuator for the valve member. When water flows from the distribution pipe through the fitting and exits therefrom via the sprinkler head to douse a fire, the paddle wheel rotates rapidly and drives the actuator via the gear train so that the valve member is shifted to close the valve opening and interrupt the flow of water therethrough after a prescribed time interval, thereby minimizing the risk of water damage to the protected premises.
