Nozzle tube for use in inert gas fire-extinguishing system for distributing inert gas in closed technical storage system, has primary and secondary nozzle sets for supplying inert gas to storage chambers and arranged opposite to storages

摘要

The nozzle tube (6) has a vertical primary nozzle set (7) and a vertical secondary nozzle set (8) for supplying inert gas to individual storage chambers (5). A terminal mold part with an integrated reduction nozzle uses the nozzle sets for producing specific amount of inert gas and pressure in the nozzle tube. The nozzle sets are arranged opposite to storages (2, 3). Nozzles (9) of the nozzle sets have identical or different diameters and are formed as slot nozzles. The nozzles are vertically positioned on equal or different height, where the nozzle tube is made of metal.
