Definitions

  • the invention relates to a closure device for extinguishing fluid-storing pressure bottles having a pressure bottle and an adapter piece for connecting a dip tube arranged in the pressure bottle to a connection piece arranged outside the pressure bottle.
  • Closing devices for extinguishing fluid-storing pressure bottles are for example from the EP 0 138 195 A2 known.
  • This device is a self-triggering extinguishing device for fire-risk devices.
  • a small pressure bottle is mounted on a device and via a blowpipe, the extinguishing fluid is discharged at a suitable location.
  • the blowpipe is closed at its end by a material which dissolves or liquefies when exceeding a predetermined temperature. This leads to a self-triggering.
  • the blowpipe is filled at rest with extinguishing fluid.
  • the extinguishing fluid is directly at the outlet. If the extinguishing fluid expands, the end piece of the blowpipe can be destroyed and extinguishing fluid could escape unintentionally.
  • thermoelastic plastic prevents material damage such as embrittlement or cracking caused by expansion stresses.
  • thermo-elastic plastic is on the one hand in the high cost, and on the other hand in the lack of fire resistance of these materials. In case of fire, it can happen that the pipes melt due to the enormous heat of the fire, and a good fire fighting is no longer possible.
  • the invention proposes that the dip tube and the connector are shaped such that the connector is partially filled with extinguishing fluid at rest, that the connector has a riser, so in that the riser pipe is at least partially above the level of the extinguishing fluid, and in that the riser pipe comprises closure means, in such a way, between the Closing means and the extinguishing fluid, a gas space is formed.
  • the closure means may be formed as a rupture disk or as a valve. When using a valve, this can be controlled by a fire alarm system and open in case of fire. This can be done electrically or mechanically. By pressurizing, which is also controlled by a fire alarm system, compressed air or gas can be driven into the pressure bottle and the extinguishing fluid are discharged. In the case of a rupture disk as a closure means, it is possible that this is brought to bursting by the pressurization, after which also extinguishing fluid can escape.
  • frost protection can not always be guaranteed by a heater.
  • a heater For example, with longer service life, it is not possible to allow a continuous heating by the battery, as this led to a discharge of the battery. The additional heating would have to be switched off for long periods. This could lead to the freezing of the extinguishing fluid and the destruction of conventional closure means.
  • destruction of the closure means is avoided.
  • the closure device according to the invention is preferably suitable for horizontal pressure bottles.
  • a horizontally arranged dip tube in the pressure bottle is immersed in the extinguishing fluid.
  • a fitting with a riser pipe is arranged, which extends vertically.
  • the riser is shaped to be at least partially above the level of the extinguishing fluid.
  • the closure means are arranged according to the invention above the level of the extinguishing fluid. Between the level of the extinguishing fluid and the closure means, a gas space is formed. Freezes the extinguishing fluid, this is done first on the peripheral expansions of the pressure bottle and the connecting pieces, ie on the inner wall of the pressure bottle and the adapter piece, in particular the dip tube, fitting and riser.
  • the riser will periodically freeze first, as it is exposed to the outside temperature unprotected. After freezing the extinguishing fluid inside the pressure bottle and the dip tube, this must expand. The expansion causes the Eispfropfen formed in the riser is pressed in the direction of the closure means.
  • the gas space between the closure means and the level of the extinguishing fluid allows the expansion and displacement of the ice plug in the riser without damaging the closure means. If the closing means were directly at or below the level of the extinguishing fluid, they would be damaged by the expansion of the fluid and the associated displacement of the ice plug. When thawing the extinguishing fluid could escape from the pressure bottle unhindered.
  • the closure device is suitable for protecting a dry system in which the pipes leading to the Lögebebeldüsen be filled with air at rest, and only in case of fire, the extinguishing fluid is introduced into the pipes. Also it would be possible to use wet systems to protect the solution according to the invention. For example, a saline solution having a lower freezing point could be kept in the pipelines.
  • the riser U-shaped It would also be possible to form the riser U-shaped. If the U is arranged so that the supply line and the discharge are below the arc, a gas space could form in the arc. In this gas space, the closure means could be arranged.
  • the interior of the pressure cylinder is pressurized with compressed air or gas via compressed air.
  • a rupture disk as a closure means
  • the extinguishing fluid is thereby pressed in the direction of the rupture disk until the bursting pressure is reached.
  • the rupture disk bursts and the extinguishing fluid is forced into the pipe until it is discharged from extinguishing mist nozzles.
  • a valve as a closure means this can be opened by a fire alarm system before the pressurization is activated.
  • the gas space is formed such that upon freezing of the extinguishing fluid in the connection piece, the frozen extinguishing fluid can expand in the direction of the closure means.
  • the gas space can be dimensioned so that the bursting pressure is not reached when the fluid expands.
  • the distance between the rupture disc and the level of the extinguishing fluid must be chosen so that a maximum, frost-related expansion of the extinguishing fluid does not drive the gas pressure above the bursting pressure. Measurements have shown that up to 9% expansion of the extinguishing fluid is possible in the case of freezing. This expansion must be absorbed by the gas space.
  • the dip tube is inclined in the direction of the inner wall of the pressure bottle.
  • the filling of the pressure bottle is preferably possible up to a degree of filling of 90 to 95%.
  • the dip tube and the connector are below the level of the extinguishing fluid, such that the dip tube is completely filled with extinguishing fluid and that the connector is filled at least to the riser with extinguishing fluid.
  • the riser is at least partially filled with extinguishing fluid. It only has to be ensured that the gas space between the closure means and the level of the extinguishing fluid is sufficiently large to compensate for the frost-caused expansion of the extinguishing fluid.
  • closure device By using the closure device according to the invention can be operated fire extinguishing equipment even if it is to be feared that the extinguishing fluid freeze temporarily freezes.
  • An admixing of antifreeze to the extinguishing fluid is preferably no longer necessary.
  • water is suitable according to an advantageous embodiment as extinguishing fluid.
  • Another object of the invention is a fire fighting system with an extinguishing fluid reservoir with a closure device according to claim 1 and one on the Pipe arranged piping, wherein the pipeline has at least one open extinguishing nozzle for discharging the extinguishing fluid, and wherein the closure means seals the pipe from the dip tube.
  • a fire fighting system with an extinguishing fluid reservoir with a closure device according to claim 1 and one on the Pipe arranged piping, wherein the pipeline has at least one open extinguishing nozzle for discharging the extinguishing fluid, and wherein the closure means seals the pipe from the dip tube.
  • extinguishing mist nozzles are used for discharging a finely distributed extinguishing mist.
  • FIG. 1 shows a fire extinguishing device 1 with a closure device 2 and a pressure bottle 6.
  • the closure device 2 is formed from an adapter piece 8, a connecting piece 12, a riser 14 and a rupture disc 18a.
  • a dip tube 10 inclined in the direction of the inner wall of the pressure bottle 6 is provided in the pressure bottle 6.
  • the dip tube 10 is below the level of the extinguishing fluid 4.
  • a Druck Kunststoffbeetzschung 22 which is provided with a check valve (not shown), in the event of fire, compressed air is introduced into the pressure cylinder 6 and the extinguishing fluid expelled from the pressure cylinder 6.
  • the closure device 2 is formed in such a way that the riser 14 preferably branches off from the connection piece 12 vertically into the vertical.
  • the rupture disc 18 a in the riser 14 is arranged so that it lies above the level 16 of the extinguishing fluid 4. Between the rupture disk 18a and the level 16 of the extinguishing fluid 4, a gas space 20 is formed.
  • the extinguishing fluid 4 freezes in the pressure cylinder 6.
  • the extinguishing fluid 4 freezes in the region of the riser 14 and the connecting piece 12.
  • the extinguishing fluid 4 freezes in the dip tube 10 and the pressure bottle 6 and expands. That in the riser 14 frozen extinguishing fluid is pressed by this expansion in the direction of the rupture disk 18a. Due to the displacement of the ice plug in the direction of the rupture disk 18a, the gas space 20 is compressed. However, the gas space 20 is dimensioned such that the frost-related increase in the gas pressure always remains below the bursting pressure of the rupture disk 18a. Extentions of up to 10% of the extinguishing fluid are compensated by the gas space 20.
  • FIG. 2 shows a further embodiment.
  • the riser 14 U-shaped. Inflow and outflow of the riser 14 are below the arc of the riser 14.
  • a valve 18 b is arranged in the gas space 20, . This valve is opened in case of fire before the pressure cylinder 6 is supplied with compressed air or gas.
  • closure device By the closure device according to the invention, it is possible to ensure a cost-effective frost-free operation of fire extinguishing systems.
