Abstract:
A valve for preventing water hammer includes a speed reduction device for reducing a speed at which the valve may be closed. A method of preventing water hammer includes closing a valve at a fire hydrant after extracting water from the fire hydrant, in which the valve comprising a speed reduction device that increases an amount of time needed for closing the valve, and operating the valve to close the valve comprises operating the speed reduction device.

Claim (Index 1):
A valve for preventing a fluid hammer effect, said valve comprising:\n a gate valve having a gate that is translated in and out of a channel of the valve by rotation of a valve handle; and a speed reduction device for reducing a speed at which said valve may be closed, the speed reduction device comprising a gear train with a gear ratio such that a number of rotations of said valve handle results in a lesser number of rotations of a screw that translates said gate with respect to said channel; wherein the gear train comprises at least three gears such that, a first two gears in the gear train reverse a direction of rotation of the valve handle as applied to a third gear, the third gear again reversing a direction of rotation applied to the screw so that a clockwise rotation of the handle will close the gate and a counter-clockwise rotation of the handle will open the gate.
