Fire-fighting device has nozzles installed in rooms of building or ship, connected at one end to supply conduit filled with extinguishing fluid

摘要

The fire-fighting device has nozzles (10) connected at one end (7a) to a supply conduit filled with extinguishing fluid. A bursting disc(33) is disposed in the area of the connecting end of the supply line(7). All the nozzles have open inserts (25), which via channels (26) in the nozzle are connected to an inflow hole (27) of the nozzle. The inflow hole issues on the face surface of an extension (29) provided with an outer thread (30). The nozzle inserts produce a finely distributed extinguishing mist when activated with an extinguishing fluid under high pressure of up to 300 bar. The outer thread of the extension is screwed into a corresponding inner thread at the connecting end of the supply conduit.
