If in the room of fire fire fire detectors and an automatic fire extinguishing system (not shown).

The work of deluge head is as follows.

Fluid under pressure is supplied into the cavity of the nozzle 10 and then goes in two directions: first, in the annular cavity 23 through radial channels 14 in the annular gap 18 between the nozzle and the Central core. When the pressure at the input of more than 0.2 MPa, the liquid is dispersed on the outer conical surface of the socket 17 with the formation of the liquid film, which is not detached from the outer surface of the socket 17. The acceleration of the liquid in the conical surface is accompanied by a decrease in her static pressure and vaporization and release of soluble gases. This phenomenon is additionally prepares the liquid to fragment into small drops. When reaching the liquid flow counter currents flowing from the cylindrical choke the s holes 19, multiple fragmentation of film formation of fine-dispersed phase.

The second direction, which supplies the fluid through the channel 12 for supplying a fluid into the cavity of the Central core, and then into the conical socket 17, from which part of the liquid will expire through radial holes 19, and a part through the conical throttle hole 22. When this happens multiple crushing trickling streams of liquid flowing from the throttle hole.

As a means of fire instead of water can be used foaming agents.
