Definitions

  • the invention relates to a sprinkler for automatic fire extinguishing systems according to the drying system for rooms at risk of frost or the like, with pieces of pipe branching down from the threaded connection of the extinguishing agent line of the system, which have a seal at the upper end and which carry the sprinkler at the lower end, in the area of which there is one , only the suspended ceiling that makes the sprinkler visible.
  • Such sprinklers are essentially not only used in rooms where there is a risk of frost (DE-OS 17 08 090). They are also used under the suspended ceilings in sales rooms in department stores or the like (DE-GM 89 09 716) if the space above the suspended ceiling is at risk of frost. In this case, an upper end of the pipe sections must be provided. In the sprinkler system according to DE-OS 17 08 090, the upper end is designed as a membrane, the durability of which is very limited.
  • the upper end is necessary so that no residual water remains in the pipe section after the system has been emptied.
  • the sprinklers are connected to the extinguishing agent line via a flexible hose section.
  • a separate suspension device is connected on the one hand variable in length to the ceiling and on the other hand to the sprinkler.
  • the hose pieces must be up to 10 bar according to the regulations be pressure tight. These pressure-resistant hoses are flexible, but cannot absorb pressure or tensile forces. This means that with variable distances between the suspended ceiling and the ceiling, the length of the hose must be adapted to the distance. This leads to difficulties when assembling on the construction site.
  • the suspended ceilings are attached to the room ceiling of the building due to structural conditions with tolerances of 2 to 5 cm. Furthermore, the pipe network for the extinguishing agent lines is laid with a slope so that the pipe network can be drained if necessary.
  • the pipe sections carrying the sprinklers must be installed at the installation sites with different lengths, which means that the pipe sections leading downward must be manufactured with different lengths on the construction site so that they are adapted to the structural conditions. Or else, the pipe sections must be manufactured in the manufacturer's workshop according to the installer's instructions.
  • the invention has for its object a piece of pipe to create hanging sprinklers for suspended ceilings in rooms at risk of frost, which compensates with the tolerances given by structural measures and the differences due to the gradient of the extinguishing agent line to the suspended ceiling without having to adapt to construction sites or workshops, thus enabling the production of such sprinklers with pipe sections.
  • the pipe sections consist of a threaded two-part upper and lower pipe, that the sprinkler with the sprinkler body is screwed into the lower end of the lower pipe, and that the sprinkler connector arresting the release member with a pipe or a rod is connected, which is screwed to a further tube or rod, which is provided at the upper end with a support body which can be pressed against a connecting piece connected to the tube, forming a valve seat, that the connecting the two tubes and the two rods Threads with the same thread pitches are formed.
  • the tube 5 is provided with an internal thread into which a lower tube 8 is screwed with its thread 9.
  • the lower end of the pipe 8 is provided with an internal thread 10 into which the sprinkler 11 is screwed.
  • the upper end of the tube 5 is provided with a further internal thread 12 into which a socket 13 with a thread 14 is screwed.
  • the socket 13 is provided with an inner, conical, downwardly widening surface 15 against which a support body 16 can be pressed with its outer surface 19.
  • the support body 16 and / or the socket 13 is provided with an annular groove 17 which is filled with a sealing ring 18.
  • the support body 16 connected to a rod 20, which can also be designed as a tube.
  • the lower end 20 is provided with an external thread 21 which can be screwed into the internal thread 23 of a rod 22.
  • a sprinkler nozzle 24 is fastened, which can form a gap with the sprinkler body 25 with its external thread 26.
  • the sprinkler arms 28 connected to the sprinkler body 25 carry at the lower end a counter socket 27 with the spray plate 29.
  • the trigger member which is designed as a glass barrel 30 in the exemplary embodiment, is firmly clamped between the two nozzles 24 and 27, the sprinkler nozzle 24 being attached via the rods 22, 20 and supports the support body 16 on the nozzle 13.
  • the special sprinkler according to the invention consisting of the pipes 5, 8, the connector 13 with support body 16, the rods 20, 22 and the sprinkler 11 with sprinkler connector 24, are completed in the workshop and delivered to the construction site. So that after screwing the tube 5 into the socket 3, the height "H" can be set, the tube 5 and the rod 20 are provided with a non-rotatable connection 32 and there is also a hexagon 34 or the like on the outside of the tube 5 which the tube 5 can be screwed into the socket 3. Likewise, the lower tube 8 and the lower rod 22 can be provided with a non-rotatable connection 31. Furthermore, the lower tube 8 is also provided on the outside with a hexagon or the like.
  • the lower hexagon 33 is smaller in the outer circumference than the upper hexagon 34.
  • the suspended ceiling is designated 35 and is provided in the area of the sprinkler 11 with an opening 36 which is made by means of a one- or two-part diaphragm disk 37 is covered.
  • the dimension "H” is different due to the extinguishing agent line 1 laid with a slope.
  • the threads 7, 9 and 21, 23 are provided with the same thread pitches, so that with a sufficient length of the thread the dimension "H" after installation of the special sprinkler and thus the length of the branched pipe section "A" can be adjusted accordingly. If the desired height "H” is set, the diaphragm plate 37, in the embodiment in two parts, is installed.
