Definitions

  • the invention relates to an extinguishing system for a combined fire-fighting vehicle, consisting of a container filled with an extinguishing powder, which is pressurized via a charging line by means of a high-pressure propellant gas filled in separate high-pressure containers, one or more consumers being connected to the container.
  • Powder extinguishing systems work according to the dry extinguishing process, with fine-grained dry extinguishing powder which is sprayed out under pressure from nitrogen or the like via hoses with connected extinguishing guns or via a powder launcher. This creates a dense cloud of extinguishing cloud, which becomes larger as the distance from the extinguishing gun or the powder launcher increases, with which a source of fire can be enveloped and the fire suddenly suffocated.
  • the extinguishing powder in the powder containers must be mixed with a compressed gas.
  • nitrogen bottles or nitrogen batteries are used, for example, which have a filling pressure of 200 bar.
  • Extinguishing systems are also known which are used to combat fire sources in rooms, e.g. Laboratories, computer rooms, computer systems, etc., can be used with an extinguishing gas.
  • Carbon dioxide (C02) liquefied under pressure, halogen hydrocarbons liquefied under pressure, such as Halon 1211 or 1301, have established themselves as gaseous extinguishing agents.
  • the extinguishing gas is filled into gas bottles and is combined into extinguishing gas batteries.
  • the combined system results in high weights because the powder systems have to be supplied with propellant gas from nitrogen cylinder batteries that are also carried on the vehicle.
  • the resulting weights are particularly noticeable in fire engines.
  • Vehicles have a permissible total weight. If the system parts are very heavy, only a small amount of extinguishing agent can be absorbed.
  • the invention has for its object, in particular for fire-fighting vehicles to provide an extinguishing system which is lighter, space-saving and less expensive and thus enables more optimal utilization of the vehicle.
  • the extinguishing system is used as a combined powder and gas extinguishing system via separate consumers, the high pressure gas being an extinguishing gas which is used for charging the powder system and for extinguishing fires, and in that the high pressure gas in the event of use a pressure reduction in the charging line is fed to the powder container.
  • the weight of the powder container can be reduced due to the reduced pressure of the propellant gas, which leads to a further reduction in the weight of the vehicle.
  • C02 or Halon 1301 can be used as propellant and extinguishing gas.
  • a preferred embodiment of the invention is that a shut-off device is provided in the charging line between the pressure reduction and the high-pressure bottle, and that a branch line provided with a shut-off valve goes out between the shut-off device and the high-pressure bottle, which branches off via a hose line in a snow pipe or another consumer ends.
  • the shut-off device can be designed as a ball valve from which the charging line provided with the pressure reducer is continued.
  • the extinguishing system 16 essentially consists of the powder extinguishing system 16a and the gas extinguishing system 16b. Both systems are supplied with compressed gas from a high-pressure bottle 2 or a gas bottle battery.
  • the powder extinguishing system 16a is equipped with three consumers 18, 19 and 20, namely a launcher tube 18 and two hose lines 19 and 20.
  • the container 1 is filled with the extinguishing powder 28. From the high-pressure bottle 2, a charging line 17 goes into the container 1.
  • a pressure reduction 23 which consists of a low-pressure regulator 5, a high-pressure regulator 3 and a pressure reducer 4 connected in between, this pressure reducer also being connected via lines 24 and 25 the charging line 17 and on the other hand is connected to the low pressure regulator 5.
  • a check valve 6 is provided in line 17.
  • two extraction tubes 21 and 22 are provided, a launcher tube 18 being arranged on the extraction tube 22 via a shut-off valve 9.
  • Hose lines 19 and 20 are provided on the extraction pipe 22 via valves 10 and 11.
  • a line 15 is provided, which is connected between the check valve 6 and the low pressure regulator 5 to the charging line 17 and is inserted into the lower end of the angled extraction tube 21.
  • a flushing line 26 is arranged, which is guided in the upper region into the container 1 and has a dust filter 27 there. Additional lines are provided via branch lines 26a and 26b, in which flushing valves 12, 13 and 14 are located. To monitor the system, an operating pressure manometer 8 and a safety valve 7 are provided in the container 1.
  • a branch line 29 is discharged from the charging line 17 at 36, a shutoff element 30 being provided behind the branch 36 in the charging line 17 and a shutoff valve 31 in the branch line 29.
  • the line 29 is guided to a hose reel 32, on which a hose line 33 is wound, which is guided via a valve 34 to a snow pipe 35.
  • Fig. 2 shows a further embodiment of the invention.
  • the shut-off element is designed as a ball valve 30a, from which a branch line 17a is led to the container 1.
  • the pressure reducer 23a and an overflow valve 37 are located in the line 17a.
  • a bypass line 39 with a check valve 38 is provided.
  • a line 40 is provided between the valve 30a and the container 1, into which a check valve 41 and a pressure control device 42 is provided.
  • the pressure control device 42 ensures a constant pressure within the container 1, the ball valve 30a being controlled accordingly.
