Definitions

  • the invention relates to a spray nozzle in the Preamble of claim 1 mentioned type for nebulization of water in fire protection systems.
  • This well known spray nozzle is in the way used multiple spray nozzles over piping connected to a common shut-off valve are.
  • the shut-off valve is through a pipeline that goes up to the shut-off valve with pressurized water is filled, connected to a water supply.
  • the nozzle openings of the spray nozzles are not closed.
  • An increase caused by a fire determining the ambient temperature is one Hose line provided that is made of a thermoplastic Material exists and with a control pressure standing water is filled.
  • the control pressure is monitored by a pressure switch or the like, through which the shut-off valve can be controlled.
  • the nozzle part 8 has on it Narrow, helical channels 12 on the outside, and between the nozzle part 8 and the cylindrical inner wall 3 or the conical inner wall 4 a swirl chamber 13 is formed which is connected to the nozzle opening 5 is connected.
  • a bracket 15 which extends from the housing 1 of the nozzle opening 5 extends away, with one on his the housing 1 facing end formed annular Area 16 attached and by screws, from of which only one screw 17 is shown as an example, releasably connected to the housing 1.
  • bracket 15th is narrow, so that in the operating state of the spray nozzle can form a spray that spreads over one extends wide area of the circumference of the spray nozzle. It is therefore only a small one by the bracket 15 Spray shadow causes the extinguishing effect of the Spray nozzle not significantly affected.
  • Fig. 4 In the rest position shown in Fig. 4 supports the pressure body 25 with its the nozzle opening 5 facing away from the screw 28 of the Support part 33 and presses with its the nozzle opening 5 facing end via the sealing sleeve 18 the Sealing disc 20 around the centering pin 21 against that Housing 1, so that the nozzle opening 5th is tightly closed.
  • the pressure body extends 25 through the elongated holes 42, 43 of the tabs 40, 41, which thus engage behind the pressure body 25, so that the legs 31, 32 in the rest position against spreading are secured.
