Definitions

  • the extinguishing nozzle head has a chamber which precedes the extinguishing nozzles in the flow direction of the extinguishing liquid. Extinguishing fluid can first flow into this chamber. In case of fire, the extinguishing fluid flows through the upstream chamber and is thereby evenly distributed to the spray nozzles.
  • additional spray nozzles are arranged in the lateral surface of the extinguishing nozzle head. These additional spray nozzles can, starting from the supply line of the extinguishing nozzle head, be arranged below the spray nozzles. The additional spray nozzles may for example be arranged such that the spray jet emerging from these additional spray nozzles no longer occurs on the deflector surface of the deflector.
  • Spray nozzles are covered themselves.
  • the radial spray directions of the additional spray nozzles, starting from the extinguishing nozzle head, can according to this advantageous embodiment, offset from the radial spray direction of the spray nozzles.
  • auxiliary spray nozzles can be arranged along a pipe or hollow body so that they are aligned in one direction, for example to spray a wall.
  • the high-pressure accumulator has a working pressure of at least 100-150 bar.
  • a pipe pressure in the pipeline can be at 10-20 bar.
  • FIG. 3 shows an extinguishing nozzle head according to an advantageous embodiment in the activated state
  • the spray nozzles 4 are arranged at angular intervals in the radial direction to the extinguishing nozzle head.
  • the spray nozzles 4 may be provided, for example, as holes within the extinguishing nozzle head 2. It is also possible that the spray nozzles 4 can be arranged as nozzle inserts, for example screwed, in the extinguishing nozzle head 2.
  • the deflector 8 is arranged circumferentially around the circumference of the extinguishing nozzle head 2. At a distance from the extinguishing nozzle head 2, the deflector surface of the deflector 8 is inclined downwards.
  • the angle of attack 12 of the downwardly inclined deflector surface of the deflector 8 can be varied according to the requirements of the spray pattern of the extinguishing nozzle head 2.
  • the length of the downwardly facing deflector surface can be varied, as indicated by different lengths left and right of the central axis of the extinguishing nozzle head is. It is also possible to vary the lengths of the deflector surfaces pointing downwards along the circumference, so that the projection of the spray pattern can be varied. For example, it is possible to make the deflector surface shorter and in some areas with a different angle of attack than in other areas. This results in that the spray pattern can be varied according to the angles of attack.
  • FIG. 2 shows an extinguishing nozzle head 2 in the activated state.
  • the glass bulb 24 has burst, and Extinguishing fluid enters the extinguishing nozzle head 2 through the supply line 3.
  • the extinguishing fluid enters the spray nozzles 4 and exits the spray nozzles 4 as a spray jet 6.
  • FIG. 2 it can be seen that the spray steel 6 impinges on the deflector surface of the deflector 8 immediately after it leaves the spray nozzles 4. As a result, the spray steel is deflected and directed downward.
  • the fluid droplets present in the spray jet are further broken by the impact and the result is a finely distributed spray pattern in the following.
  • This spray pattern is characterized by a conical, uniform distribution of fluid droplets.
  • Extinguishing fluid flows under high pressure, for example between 10 and 150 bar from the high-pressure fluid container 26 into the pipe 28 and then into the extinguishing nozzle heads 2.
  • the extinguishing nozzle heads 2 spray the extinguishing fluid as a finely divided mist with droplet sizes between 10 and 500 microns, preferably between

Abstract

Pour la lutte contre l'incendie, un corps de buses d'extinction (2) destiné à la pulvérisation d'un liquide d'extinction ainsi qu'un dispositif de lutte contre l'incendie sont proposés. Le corps de buses d'extinction se caractérise par au moins deux buses de pulvérisation (4) disposées le long de la circonférence du corps de buses d'extinction (2) et par au moins un déflecteur (8) placé dans la zone du jet pulvérisé (6) du liquide d'extinction sortant des buses de pulvérisation (4). Pour une lutte efficace contre l'incendie, on règle un angle de pulvérisation (10) du jet pulvérisé par rapport à la surface circonférentielle du corps de buses d'extinction (2), un angle d'incidence (12) du déflecteur (8) par rapport au sens du jet pulvérisé (6), une distance (14) du déflecteur (8) par rapport à la surface circonférentielle du corps de buses d'extinction (2) et une pression élevée du liquide d'extinction de telle sorte que le jet de pulvérisation prenne une forme conique.
