ACTUATION MECHANISM FOR WATER HAMMER VALVE

摘要

The present invention discloses an actuation mechanism for a water hammer valve. The water hammer valve is initially prevented from operating, and an actuation mechanism for the water hammer valve is actuated by dropping one or more balls or other objects onto the valve. Once actuated, the pilot and piston mechanism in the water hammer valve operate to produce hydraulic pulses from an upstream pressurized fluid.

主权项

1. A flow-actuated valve comprising:
a housing with an inlet and an outlet, wherein the flow-actuated valve is configured to periodically actuate and at least partially interrupt fluid flow through the housing; and a releasable lock configured to initially prevent actuation of the flow-actuated valve, wherein the releasable lock is released by increasing the differential pressure through flow passages in the releasable lock.
