Definitions

  • the invention relates to a sprinkler system for rail vehicles with at least one liquid container which can be connected to a pressure medium container via a pressure medium line and pressurizable, and with a number of thermally triggerable sprinkler nozzles which are connected to the liquid container via a liquid line.
  • Sprinkler systems are also increasingly being used in rail vehicles to extinguish or at least contain fires that break out.
  • thermally triggerable sprinkler heads When using known, thermally triggerable sprinkler heads, the system or parts thereof are constantly filled with pressurized water. Exceeds the temperature at the trigger, e.g. B. a glass ampoule, a sprinkler head a certain value, for. B. 90 ° C, z. B. the ampoule and releases the sprinkler outlets.
  • a system that is constantly under pressure has several disadvantages, e.g. B. triggering sprinkler nozzles through vandalism. This can often be found in railways or subways - a problem that hardly plays a role in department stores or public buildings, for example.
  • extinguishing agents e.g. B. water
  • d. H. when triggered z. B. transported by smoke detectors or when triggered manually by electrically operated pumps to the sprinkler nozzles.
  • the power supply is not guaranteed.
  • both the power supply and the compressed air supply can fail - a circumstance that should not be neglected when designing sprinkler systems.
  • An object of the invention is to provide a sprinkler system which ensures the highest possible level of safety of its function with simple maintenance and vandalism tolerance.
  • a sprinkler system of the type mentioned at the outset in which, according to the invention, an electromechanical alarm valve controlled by a fire alarm system is connected in the pressure medium line between the pressure medium container and the liquid container, which valve is closed in normal operation, but is open in the event of an alarm, so that in the alarm all of the liquid containers and the liquid line to the sprinkler nozzles is pressurized.
  • the invention ensures that the sprinkler system is immediately ready for use in the event of an alarm, but is otherwise depressurized, which has the advantages that vandalism on sprinkler nozzles does not lead to water damage, maintenance work is simplified and corrosion and material stress due to pressurization in the sprinkler system are prevented.
  • the pressure medium container is connected to the pressure medium supply of the rail vehicle via at least one check valve. In this way, a drop in compressed air, e.g. B. by damaging a compressed air line, do not endanger the function of the system.
  • liquid line is connected to a lower dry extinguishing line with an external connection via a non-return valve, it is possible to supply extinguishing water from the outside in the event of a fire in the event of a draft, which can also contain fire in the underfloor area.
  • the liquid line leads both to sprinkler nozzles for the ceiling cavity of the vehicle and to sprinkler nozzles for the passenger / interior.
  • the non-visible ceiling cavity can also be detected, it being expedient if the sprinkler nozzles for partial areas of the rail vehicle, for. B. the ceiling cavity, can be triggered at a higher temperature than the sprinkler nozzles for the passenger / interior. As intended, these subareas usually have higher temperatures than the ambient temperature of the vehicle.
  • At least one liquid container FBH is provided in the rail vehicle SFZ and is connected to a pressure medium container DMB via a pressure medium line DML and an alarm valve AVE.
  • a pressure medium container DMB In order to achieve a separation between the pressure medium, generally compressed air, and the water in the liquid container FBH, a rubber bubble GBL or the like is provided in a known manner in the liquid container FBH.
  • a liquid line FLL leads from the liquid container FBH to sprinkler nozzles SDF in the ceiling area of a passenger compartment FGR and to sprinkler nozzles SDD in the ceiling cavity above the passenger compartment.
  • passenger compartment does not of course exclude that the system can be provided in the same way for wagons and traction vehicles of any type and purpose (e.g. freight wagons), which then do not have a "passenger compartment", but rather an interior, a loading area or have an area for the transportation of people and goods.
  • the liquid line leads via a check valve RSW to a dry extinguishing line TLL in the underfloor of the SFZ rail vehicle.
  • This dry extinguishing line TLL has spray or spray nozzles and can, if necessary, extinguish or contain a fire in the underfloor of the SFZ rail vehicle.
  • the dry extinguishing line TLL has an external connection AAN, e.g. B. provided with a so-called "C-pipe" connection.
  • the sprinkler nozzles SDF for the passenger compartment FGR and SDD for the ceiling cavity DHR can be thermally triggered.
  • H. z. B. provided in a known manner with a glass ampoule which bursts at a certain temperature and releases the sprinkler outlet of the corresponding nozzle.
  • the sprinkler nozzles SDF for the passenger compartment FGR are usually triggered earlier, e.g. B. at temperatures between 70 and 100 ° C, than the sprinkler nozzles SDD for the ceiling cavity DHR, which only trigger at temperatures of 200 to 250 ° C, for example.
  • the ceiling cavity is often subject to strong solar radiation, which can normally lead to very high temperatures of 60 to 70 ° C, so that triggering it at lower temperatures would cause unnecessary damage.
  • the pressure medium tank DMB is connected to the compressed air line DLL of the rail vehicle via a manually and electrically operated feed, shut-off and vent valve AEV and via a check valve RSD. If the AEV valve is switched accordingly, compressed air can flow out of the pressure medium container DMB via an outlet opening ALO.
  • the alarm valve AVE is connected via a control line asd to a fire alarm system BMA or quite generally to a control system, a vehicle bus BUS usually containing the various control lines.
  • the valve AEV is also connected to the vehicle bus BUS via a control line dsd.
  • smoke detectors RDD are provided at suitable points in the interior or passenger compartment FGR of the rail vehicle SFZ and they are connected via a sensor line and the bus BUS to the fire alarm system BMA or the control STE.
  • the pressure in the pressure medium tank DMB is recorded by a manometer and passed on to the control SDE via a corresponding signal line msl and the bus BUS.
  • the figure shows only one half of the rail vehicle SFZ and the "right" half of the vehicle, which is not shown in the drawing, is essentially a mirror image, with the half, not shown, generally also having a liquid container FBH and a pressure medium container DMB with corresponding valves, etc. contains, but does not necessarily have to contain.
  • the alarm valves AVE of the individual wagons or rail vehicles SFZ are controlled via the smoke detectors RDD of the passenger compartment and, if applicable, those that are also in the ceiling cavity DHR, and thereby block the connection between the pressure medium container DMB and the liquid container FBH.
  • this control is carried out in a known manner via a safety loop including the BMA fire alarm system or the STE control system.
  • compressed air feed valves not shown here, are also activated via the control system of the train and the pressure medium container DMB is pressurized with compressed air via the check valve RSD.
  • the control and fire alarm system SDE and BMA are set up to ensure that compressed air is not exposed when the smoke detectors or alarm valves are not working.
  • a smoke detector RDD reports a fire when smoke develops in the passenger compartment or in the ceiling cavity
  • the smoke safety loop of the respective wagon is interrupted and the alarm valve AVE is opened.
  • This valve is built in such a way that it is open when de-energized, but is closed when energized.
