Definitions

  • the invention relates to a hollow jet nozzle for fire-fighting purposes, with at least one supply of extinguishing agent Housing and at least one beam outlet.
  • a rotatable panel system is also used, in which a decentralized water supply is arranged.
  • Various nozzle shapes are attached to the panel, which are then swiveled in front of the water supply.
  • the disadvantage here is that only one jet shape can be achieved and the system is unsuitable for larger extinguishing quantities and high pressure use due to sealing problems.
  • the invention has for its object to provide a hollow jet nozzle which consists of only a few parts, making it easier to use offers and in addition to the conventional functions also for flat jet generation both in high pressure and normal pressure operation suitable is.
  • FIG. 5 In the front part of the controller 2, FIG. 5, either interchangeable flat jet-generating inserts 15 or forms, FIGS. 2, 3 and 4, which are fixed in the controller 2, can be produced.
  • the interchangeable inserts have the advantage, particularly when using high pressure, to individually determine a specific extinguishing quantity, throwing distance and jet width.
  • the axial displacement of the controller can vary depending on the use remotely operated by electrical, - pneumatic, - hydraulic drives or be done manually.
  • the housing according to Fig. 1 - shown here with a square flange (3) - has an annular gap 4 which is provided with a plurality of ribs 5 for generating a spray jet.
  • the full jet is generated in the front cylindrical part 6, which connects to the inner bore with a cone 7.
  • the angle of the cone7 in the housing corresponds to the angle of the cone8 in the front part of the controller2.
  • Extinguishing agents for full jet and in the rear area for spray jet are directed over the ring cross-section 9 of the guide ring 10.
  • the guide ring 10 is connected to the inner cylinder 12 via the ribs 11.
  • the entire length of the inner cylinder 12 has a cavity which opens into the outlet opening 13, which ensures clean flat jet generation with its special nozzle shape.
  • the controller 2 is pushed axially forward and can discharge the extinguishing agent in the ring cross section 9 between the guide ring 10 and the inner cylinder 12. If it makes sense to simultaneously dispense a flat jet, a flat jet can be generated via the cavity 14 and the outlet opening 13. If only a flat jet is to be emitted, the ring cross section 9 is blocked off and extinguishing agent is only supplied via the cavity 14.
  • the controller 2 When generating a flat jet or / and spray jet Fig. 3, the controller 2 is pushed back as far as it will go so that an extinguishing agent cannot flow out at the front.
  • the extinguishing agent is then dispensed via the ring cross-section (9) and the annular gap 4 of the housing 1 as a spray jet and / or via the cavity 14 and outlet gap 13 as a flat jet.
  • a discharge which is advantageous for high-pressure use can take place simultaneously via the ring cross-section 9, a spray jet -ring gap 4- and a full jet in the front area. If there is a sensible delivery of flat jet, this can be done as explained above.
  • the quantity control of the extinguishing agent can either be shifted the controller2 or by a separate metering device and automatic and manual pressure control of the fire-fighting centrifugal pump be made.
