Definitions

  • the invention relates to a water nozzle according to the preamble of claim 1.
  • a water nozzle is from the DE 10 2013 005 972 A1 known. It has at least two separate water ducts, through which also separately controllable different water volume flows are directed to a flow head. At the flow head, the water volume flows combine to form a ring stream. Depending on which of the volumetric flows is greater, this results in a slender, bundled ring beam or a more or less expanded ring beam.
  • the invention is therefore an object of the invention to provide a water nozzle with cut-off function for the water jet available, which is structurally simplified even at high water pressures and thus large throw lengths of the water jet can be used.
  • This object is achieved by a water nozzle with the features of claim 1.
  • a ring stream is generated from at least two water volume flows supplied via separate water guides on the flow head. This is formed by varying the water volume flows either bundled as a narrow beam substantially or widened funnel-shaped.
  • the water nozzle according to the invention also has a deflecting element, which has a central outlet opening arranged at a distance from the flow head in the jet direction downstream of the flow head. Its diameter is dimensioned so that a slender jet can pass unhindered, while an expanded jet bounces against a deflector which extends around the outlet opening.
  • a slender ring beam can be changed abruptly to a widened beam, which as it were cut off no more water jet emerges from the outlet opening, since the expanded jet can not pass this and is deflected in the deflection.
  • the deflection device comprises a central body with expanding in the flow direction outside diameter, in the middle of which the outlet opening is located.
  • the enlarging outer diameter forms baffle and guide walls, which achieve a deflection of a widened water jet as strong as possible and thus also recoil and low-spray.
  • This central element can be conically shaped in the lower region, in the manner of a bottle stopper.
  • the water nozzle preferably has a guide tube for the annular jet extending from the flow head to the outlet opening. This prevents rebounding or dripping water or other external influences, such as wind, from influencing the ring beam, in particular if it should be designed as a slender jet for passage out of the outlet opening.
  • the deflecting element may preferably have a hood or be configured overall in a substantially hood-shaped manner, wherein the hood extends at a distance around the flow head.
  • the hood can be shaped like a cylinder pot, with the outlet opening in the upper hood center or in the "pot bottom".
  • the hood-like design redirects rebounding and diverted water of the funnel-shaped expanded jet back into a rear / lower area and channels with it water flows, so that when cut / deflected jet around the water outlet as possible no water flow is visible.
  • the hood extends behind the flow head in the flow direction, so that it partially surrounds the water ducts. This redirects the diverted stream of water back to an area that normally escapes viewers' insights. In addition, this extended deflection of the recycled water sufficient speed withdrawn, so that no recoil turbulence occur.
  • the water nozzle is mounted by means of a holder such that as few visible parts of the water nozzle protrude from the surface of an ambient medium.
  • this surface is a water surface
  • flow head and water outlet are to be arranged above the water surface, while the rear end of the hood extends to below the water surface, so that returning water of the fanned beam is passed under the water surface and thus remains invisible to the viewer.
  • the surrounding medium is, for example, a gravel bed
  • the nozzle can be arranged such that only the water outlet protrudes above the surface of the gravel bed, while the hood dips back into the gravel bed with its rear end.
  • the hood need not be longer than the distance between the flow head and the water outlet, but only cover the visible, protruding area.
  • FIG. 1 illustrated water nozzle is in the illustrated application with a holder 1 in a surrounding medium 2 of a water reservoir arranged such that an outlet opening 3 of the water nozzle from the surface 4 of the water reservoir 2 emerges.
  • the water nozzle is generated illustration 1 a slender beam 5 in a large parabola.
  • Fig. 2 shows the nozzle Fig. 1 on average, but without water reservoir and without water flow rates.
  • the function of the nozzle is in the Fig. 3 and 4 illustrated.
  • the nozzle has a first port 11 for a first pump, not shown.
  • This pumps a water volume flow V1 in an annular water guide 6, which is formed by the gap between an inner tube 7 and an outer tube 8 of the nozzle.
  • a second pump likewise not shown, pumps a water volume flow V2 via a second connection 12 into the further water flow, which is formed by the inner tube 7.
  • a flow head 13 which is essentially formed of an outer flow control arm 14 and an inner flow control arm 15.
  • Both flow control arms 14, 15 are preferably adjustable and combine the water volume flows V1 and V2 at the exit from the flow head 13 to a sharply defined annular beam 5.
  • the adjustability of the flow guide 14, 15 serves to Einjust réelle the ring beam 5. This extends without contact through a guide tube 17 to a deflecting element 18, which is formed in the embodiment shown here as a hood. This comprises the arranged in the beam direction S after the flow head 13 and spaced from the flow head 13 central outlet opening 3, through which the ring beam 5 in Fig. 3 exits unhindered.
  • Fig. 4 shows an alternative operating state of the water nozzle.
  • the volumetric flow V2 was increased relative to the volumetric flow V1 or the volumetric flow V1 was reduced compared to the volumetric flow V2.
  • a funnel-shaped flared annular jet 5 ' is formed at the flow head 13. This can not pass the outlet opening 3 due to its expansion. Rather, the widened ring beam 5 'is deflected by means of a deflection device, which is part of the deflecting element 18 or in this case the hood.
  • the jet bounces 5 'against baffle and guide walls 22 of a central body 21 and from there, if necessary, with further deflection by the closed end face 28 and the side walls 38 of the hood 18 back in the direction of the arrows R.
  • the hood 18 extends behind the flow head 13 as viewed in the flow direction S.
  • Fig. 1 shows that in particular a return of the water backflow R under the surface 4 of an ambient medium 2 or water reservoir takes place.
  • the water nozzle according to the invention can be operated with high water pressures, resulting in large throw heights or widths for the water jet 5.
  • V1 and V2 further effects are possible, such as e.g. a variation of the throw or the generation of a slightly wavy beam.
  • pumps are suitable for this, whose speed can be controlled electronically.
