| The ongoing development of increasingly hazardous energetic or explosive materials requires concurrent improvements in the safety system used for their handling and storage. High-speed fire protection and suppression systems are an important response to the risks of those evolving materials. Pressurized containers are a typical mechanism for the discharge of fire suppression agents in explosion suppression systems. However, the limited volume of fire extinguishing material present in a pressurized container can be problematic, and systems that have an unlimited supply of fire extinguishing material, such as a pilot-actuated spraying or sprinkler system, are slow to respond. Naval Surface Warfare Center, Crane Division (NSWC Crane) has developed, patented, and fielded an ultra high-speed deluge water spray valve . The new valve significantly reduces the response time to deliver water and increases the spray volume. The ultra high-speed water valve or nozzle combines technology used to rupture the discs found in pressurized, container-based fire suppression systems with that found in fixed pipe spray and sprinkler systems. The nozzle 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. This nozzle combines the fast response time of a pressurized container suppression system with the unlimited supply of fire extinguishing material of a spray or sprinkler suppression system. Advantages: - Faster response time - Higher water volume - Easy to reset Potential Applications: - Explosives manufacturers - Pyrotechnics - Mining - Fire suppression - Military |
