Definitions

  • the present invention relates to a rotating nozzle element for projecting a liquid such as water, in the form of a cloud.
  • a liquid such as water
  • a cloud such an element can be used on a sprinkler fire extinguishing system, to create a cloud of cold water.
  • the rotary nozzle element is not limited to the field of fire extinguishing systems and can be used in any other technical field in which the generation of a cloud of liquid, such as water, is sought.
  • An object of the invention is to provide a simple and reliable system that can generate such clouds.
  • the element according to the invention comprises a main body on which is mounted a rotating nozzle which rotates in order to create the cloud of the liquid dispensed, such as water, as will be described below with reference to FIGS. attached.
  • FIG. 1 and 2 we see a first sectional view ( Figures 1 and 2 ) and in perspective ( figure 1 ) of the element 1. It comprises a body 2, for example of cylindrical shape and forming a cage, in which a nozzle 3 is mounted free to rotate by means of bearings 4, 5.
  • pressurized air enters the body 2 through the inlets 6 and passes through the upper part of the fire.
  • the nozzle 3 in a hole 7 by pressing a locking piston 8.
  • the piston is held in the locking position by a capsule 9.
  • the ducts 10 also comprise at least one, but preferably several, lateral outlet (s) 11 for the air which make it possible to create the rotation relative to the body, in the manner of a helix.
  • the pressurized water is evacuated by the small nozzles 16 ( figure 4 ) which open above the openings 11 which in turn allow the air to escape under pressure.
  • an expander coupled to the device is used.
  • the rotating nozzle creates a cloud of water by rotation generated by the air and spraying water leaving the nozzles 16.
  • the rotary nozzle may comprise more than two branches as shown in FIGS. Figures 1 to 4 .
  • a pressure reducer (or other equivalent system) is also used in order to maintain a constant pressure at the level of the small nozzles 16 .
  • the principle of the invention can be used in any installation, not just to fight a fire.
  • the capsule 9 may be replaced by another equivalent retaining means to hold the locking piston in position and release it when desired, thereby triggering the mechanism and the rotation of the piston. nozzle.
  • the system according to the invention can be manufactured in any material which is adapted to the intended use: metal, synthetic material, etc.
