BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to high-speed fire protection/suppression systems
and, more particularly, to fast response fluid flow control nozzles incorporating
a frangible element that is designed to be ruptured to release said material.
2. Description of the Background
The ongoing development of increasingly hazardous (i.e. energetic or explosive)
materials requires concurrent improvements in the safety systems associated with
their handling and storage. High-speed fire protection/suppression systems represent
one of the most important safety systems associated with those evolving materials.
High-speed fire protection/suppression systems take a number of forms. Common forms
include (1) fixed pipe pilot-actuated spraying/sprinkler systems incorporating
poppet valve-based nozzle assemblies and (2) pressurized containers of fire extinguishing/suppressing
material (e . . . . More |

Disclosed herein is a fast response fluid flow control valve/nozzle that
combines the technology used to rupture the frangible discs found in pressurized
container-based fire protection/suppression systems with that found in fixed pipe
spray/sprinkler systems. The apparatus'' design projects a small, localized pressure
wave at the underside of a frangible disc that is sufficient to rupture the disc
in a very rapid manner. The present invention generally comprises an assembly of
six primary components; a chamber base, a jet core threaded into the chamber base,
a commercially-available rupture/frangible disc assembly, a disc retention ring,
a nozzle port threaded onto the chamber base to hold the retention ring and rupture
disc against the jet core and to tie the components together as a unitized assembly,
and a pressure cartridge actuator. |

1. A fast response flow control valve/nozzle for a high-speed fire protection/suppression
system, comprising:
a base defining the outer walls of an internal chamber and comprising internal
threads at a first end, external threads at said first end, and at least two mounting
ports proximate said first end in fluid communication with said internal chamber;
a jet core defining the inner walls of an internal chamber and comprising external
threads at a first end, said external threads at said first end being releasably
attached to said internal threads at said first end of said base;
a frangible disc proximate said first end of said jet core and said first end
of said base;
a retention ring releasably attached at said first end of said base, whereby
said frangible disc is positioned between said retention ring and said first end
of said jet core;
a nozzle port defining a central bore and comprising internal threads at . . . . More |
