Definitions

  • the invention relates to a device for Firefighting with compressed air foam, which is a pump for Generation of a water and foam concentrate existing flow of extinguishing agent and one to the Extinguishing agent flow connected pressure source for Generation of the compressed air foam includes.
  • the foam layer also has one separating effect with regard to the combustion process inhibitory atmospheric oxygen access to the fire material, the Air bubbles contained in the foam also heat record and thus to improve the extinguishing effect contribute.
  • the compressed air With reduced water consumption Damage caused by the extinguishing water clearly reduced.
  • the compressed air also makes them big Throwing distances achieved, and the hoses are due to the Air fraction easy to handle.
  • the invention has for its object a Fire fighting device with compressed air foam too develop that are designed to be lightweight and space-saving as well can be easily integrated into a fire engine is and in wet foam, dry foam and Extinguishing water area safely and with little effort is controllable.
  • the basic idea of the invention is in that for the foaming of water and Extinguishing agent mixture of foam concentrate anyway necessary compressed air also as a drive and Control means for the flow of extinguishing agent generating, self-priming diaphragm pump is used.
  • the system can therefore operate without additional drive energy driven and solely by regulating the Compressed air supply to the pump controlled independently of energy become.
  • compressed air bottles as The device can be a separate source of pressure medium portable unit can be used independently of external energy can be used anywhere.
  • the Compressed air cylinders that are standard equipment in the Firefighters belong to can be easily exchanged become.
  • Compressed air foam extinguishing device instead of the compressed air cylinders with a compressor as Compressed air source.
  • a compressor as Compressed air source.
  • it is Device for a fixed installation on a Fire engine provided.
  • the each has a different amount of compressed air changed pump output and thus a certain Extinguishing agent flow rate result, so that at constant compressed air supply for foaming with With the help of a fixed through valve, either wet foam or dry foam available can be put.
  • the system can also can only be operated with non-foamed extinguishing agent. Due to the permanently set compressed air supply for the Different operating modes can be the invention Device can be operated easily and without errors.
  • the compressed air is supplied for operation the system from one to two in the fire service Usually used compressed air bottles 1 formed Compressed air reservoir.
  • a pressure reducing valve 2 is integrated, of which a pump drive compressed air line 15 and one Foam generation compressed air line 16 branches.
  • the Pressure reducing valve 2 is controlled by a sensor Signal generator 3, here: a horn, downstream, one Operator the impending emptying in time of compressed air bottles 1 signals.
  • the pump drive compressed air line 15 through a Main valve 11 is closable, branches into two Sub-lines 15 ', 15' ', into each one Shut-off valve 13 and a dry foam operation needle valve 4 or a shut-off valve 12 and a wet foam operation needle valve 5 are involved.
  • the common Pump drive compressed air line 15 is connected to a Diaphragm pump 8 coupled to the suction side with a Fire water tank 9 connected and on the pressure side has an extinguishing agent discharge line 10.
  • the Foam generating compressed air line 16 in which a firm adjustable needle valve 7 for regulating the Extinguishing agent to supply air and foam a shut-off device 6 designed as a ball valve are connected to the extinguishing agent discharge line 10 connected.
  • the extinguishing agent in the extinguishing water tank 9 is in the form of a mixture of water and one Foam concentrate before.
  • the shut-off valve is activated during dry foam operation 12 closed and the shut-off valve 13 opened, so that via the fixed dry foam operation needle valve 4 a defined amount of air to the diaphragm pump 8 streams.
  • the Diaphragm pump 8 promotes the Diaphragm pump 8 a certain amount of extinguishing agent (from Water and foam agent mixture) into the Extinguishing agent discharge line 10.
  • Foam generating compressed air line 16 via the needle valve 7 a defined amount of air in the Blown out extinguishing agent line 10 and thereby to Generation of a dry foam for fire fighting the extinguishing agent is foamed.
  • the compressed air supply via the dry foam operation needle valve 4 to the diaphragm pump 8 and the flow rate of the extinguishing agent determined thereby and the quantity fixed via the needle valve 7 set compressed air supply to that of the diaphragm pump 8 extinguishing agents are coordinated so that for the extinguishing process a dry foam in proportion of 1 part extinguishing agent (mixed with foam agent Extinguishing water) and 21 parts of air is available.
  • the shut-off valve 13 is used for wet foam operation closed and the shut-off valve 12 opened.
  • About the Wet foam operation needle valve 5 becomes the diaphragm pump 8 to promote a fixed, larger Extinguishing agent amount a certain larger amount of air from the Compressed air bottles 1 supplied while the over the Foam generating compressed air line 16 in the Extinguishing agent discharge line 10 blown air constant remains.
  • Simply because of the firm attitude of the Wet foam operation needle valve 5 and the needle valve 7 in the foam generating compressed air line 16 is a Wet foam in the ratio of 1 part extinguishing agent to 7 Share air creates.
  • shut-off device 6 ball valve
  • at least one Shut-off valve 12, 13 is open.
  • compressed air only serves to drive the Diaphragm pump 8 for conveying extinguishing agent from the Extinguishing agent container 9 without the extinguishing agent in the Extinguishing agent discharge line 10 is foamed.
  • the device described above is exclusively on the basis of compressed air as drive and Control means and as a foaming agent possible, depending on the type of fire dry foam or wet foam or non-foamed extinguishing agent for fire fighting deliver.
  • the device needs no other than air further drive or control energy.
  • By mere Switching the shut-off device 6 and the Shut-off valves 12, 13 can be optimal for fire fighting set wet foam or dry foam or also unfoamed extinguishing agent can be used.
  • the device is simple, lightweight and dry foam designed to save space, the drive elements being the available to the fire department anyway Air cylinders can be used. Due to the easy switching between wet foam, Dry foam and pure extinguishing agent operation is the Device user-friendly and in terms of Foam type can be handled safely.
  • the extinguishing agent as a mixture of water and Foam concentrate ("premix") already in the Device integrated extinguishing agent container 9 before. It it is also conceivable that in the extinguishing agent container only water is stored and with one in the Extinguishing agent discharge line 10 integrated admixer a separate foam concentrate container Foam agent in the pumped by the diaphragm pump Extinguishing water flow is entered and then the Airflow for foaming is supplied. In this case can also replace the extinguishing agent container step into another water reservoir.
  • a fire fighting device designed in this way with compressed air foam instead of as a compressed air source the compressed air cylinder is provided with a compressor 17, shows the embodiment of FIG. 2.
  • FIG. 2 are which agree with the embodiment of FIG. 1 Parts of the device with the same reference numerals designated. Except for the use of a compressor 17, which is connected to the engine of the Fire engine is coupled, differs this embodiment variant from the representation in FIG. 1 essentially in that an extinguishing agent container 18 for water, a foam agent container 20 and one in the extinguishing agent discharge line 10 before Junction of the foam generation compressed air line 16 integrated foam agent mixer 19 are provided. Due to the arrangement of a compressor 17 that in the variant of FIG. 1 required pressure reducing valve and the acoustic signal generator is not required.
