Definitions

  • the invention relates to an extinguishing device for fighting fire and tarnishing Explosions, the at least one closing an extinguishing agent container and one Contains predetermined breaking point burst membrane.
  • DE 42 24 184 A 1 describes an extinguishing device in which the Extinguishing agent container is closed to the outside by means of a convex bursting membrane, which is provided with circular and radial predetermined breaking points. This membrane opens already at an overpressure of 0.1 to 1.0 bar.
  • Gas pressure generator connected, which causes a mixing of the Extinguishing agent with the compressed gas and this mixture in the room to be extinguished sprayed.
  • the extinguishing agent is only atomized after it has been expelled from the container.
  • This one used membrane shape does not allow compensation for the change in Extinguishing agent volume depending on the temperature.
  • the invention has for its object a bursting membrane for an extinguisher to improve the type mentioned so that the aforementioned disadvantages are avoided and that a central rupture of the bursting membrane and thus a uniform one Extinguishing agent distribution is achieved.
  • the solution is simple with the help of the characteristic features of the Main claim achieved, an advantageous embodiment results from the features of subclaims.
  • the particular advantage of the bursting membrane according to the invention lies justified by the fact that by means of the flat surface or the depression in the center of the Bursting membrane makes it easier to turn the membrane inside out if pressure is applied becomes without a local bulge, the bursting membrane behaves similar to a disc spring.
  • the designed according to the invention Bursting membrane compensate for temperature expansion of the extinguishing agent because the level Surface or the recess in the center of the membrane is axially resiliently movable.
  • Another advantage is the circular shape of the flat surface in the center the bursting membrane, through which an even load distribution when pressurized is achieved. This in turn supports an even turning of the membrane and prevents side dents. Finally, the inversion process on Weakened predetermined breaking point provided at the edge of the bursting membrane before breaking through, so that the actual breaking process takes place simultaneously over the entire circumference and that Extinguishing agent is expelled uniformly.
  • an extinguishing device 1 in a known design, the one contains pyrotechnic gas generator 2.
  • the pyrotechnic gas generator 2 concave bursting membranes 3 and 4 that are curved towards the gas generator close the extinguishing agent cartridge 5 in such a way that the extinguishing agent 6 does not escape can.
  • the bursting membranes 3 and 4 are spherically shaped and have in their Membrane surface predetermined breaking points. In the case of pressurization, such bulge Bursting membranes randomly at some point or at a material-related one Vulnerability. If there is a pronounced dent, the closest one begins Break open predetermined breaking point.
  • the invention proposes that Shaping bursting membranes as shown in Fig. 2.
  • the center of the Bursting membranes 7 formed as a flat surface.
  • the central flat surface is achieved that temperature-related volume fluctuations by means of a resilient Movement of the flat surface in the direction of the main axis A of the extinguishing device 1 be balanced.
  • both of them turn over Membranes 7 around and weakened by the inversion process Breaking points 8 tear open.
  • the bursting membranes 9 are convex in their central area, that is, from the compressed gas generator curved away, trained. This shape of the membranes affects positive on the central focus of the pressure applied by the gas generator 2.
  • FIG. 4 finally shows the process of turning the two bursting membranes 7 inside out, which are shown in Fig. 2 in the Ruhr state, under the influence of the upcoming Gas pressure (arrows).
  • the predetermined breaking points 8 are opened first Buckling and then subjected to tension. Along the break line of the two Breakthroughs 8 occur simultaneously.
  • the rest position of the right Bursting membrane 7 is shown in FIG. 4 with a broken line.
