Abstract
A sprinkler accelerator system includes an accelerator and at least one orifice. The accelerator is coupled with at least one pipe coupled with at least one sprinkler, and vents gas from the at least one pipe when the at least one sprinkler opens. The at least one orifice controls a rate of change of pressure in the at least one pipe to control operation of a flow control valve coupled with the accelerator.
Claims15
A sprinkler accelerator system, comprising:
- an accelerator comprising:
- at least one accelerator opening coupled with at least one pipe, the at least one pipe coupled with at least one sprinkler, a gas including at least one of air and nitrogen in the at least one pipe;
- a vent;
- and
- an actuator assembly that moves, responsive to a rate of change of a first pressure applied by gas in the at least one accelerator opening satisfying a pressure rate threshold, to couple the at least one accelerator opening with the vent;
- and
- at least one orifice coupled with the at least one pipe to adjust the rate of change of the first pressure responsive to the at least one sprinkler changing to an open state.
