Definitions
- the invention relates to a fire extinguishing device for rail vehicles with a stationary container for extinguishing liquid, which is connected to a check valve with compressed air is charged, and one connected to the stationary container Extinguishing agent line with flow detector and sprinklers.
- Fire extinguishing devices of this type are known for example from GB-A 2 139 495. They are used as self-acting with selective extinguishing with extinguishing fluid Extinguishing system, also called sprinkler system, for fire protection and fire fighting in vehicles, e.g. B. installed in a train carriage, response and functioning of a system of a train part independently of that of the others Systems in other train parts can be.
- Extinguishing system also called sprinkler system
- extinguishing liquid can flow with the air through the compressed air system transported or distributed and on built-in technical vehicle installations, such as B. the brake control and electrical connections, sprayed will. Springs and other sensitive control parts, bare metal surfaces and cable connections are massively exposed to material attack by corrosion, so that malfunctions occur and operational safety is no longer guaranteed is.
- a container with a flexible inner casing is known through which draws the compressed air from a liquid inside the container is separated.
- the compressed air is used to increase the liquid volume expel the air chamber from the constant volume container.
- the invention is therefore based on the object of a fire extinguishing device to improve the type mentioned at the outset in such a way that, on the one hand, a transfer of Extinguishing liquid in the compressed air system and on the other hand an escape of compressed air from the sprinklers is safely avoided. It is also an object of the invention Functional reliability of fire extinguishing equipment, especially with regard to the year-round weather-independent use to improve through Avoid leakage caused by temperature fluctuations or material tension.
- This task is performed in a generic fire extinguishing device by characterizing features of claim 1 solved.
- This plastic which is free of heavy metal ions, is a Made of cross-linked polyethylene, which is very insensitive to Stress cracking is and excellent creep resistance even at higher ones Temperatures (up to 110 ° C) and heat aging resistance.
- the extinguishing agent under pressure are its other good properties, such as freedom from corrosion and the Resistance to chemicals and deposits, as well as the peculiarity itself static charge, very cheap.
- Corresponding extinguishing agent pipes stand out also due to dimensional stability at short-term high temperatures up to 210 ° C, high abrasion resistance and notch sensitivity combined with good Restoring forces (memory effect) when buckling.
- the fire extinguishing system shown is an extinguishing system such as that used, for example is used for underground or elevated railway vehicles.
- the extinguishing liquid is there from water mixed with glycol, which is pre-stressed with compressed air Container 1 in a rubber-made liquid reservoir, also called hydraulic accumulator 2.
- the compressed air is supplied via a check valve 3 and an air filter 4, which are arranged one behind the other are in an air line 5, the container 1, wherein by means of in the air line 5 stop valve 5a container 1, check valve 3 and Air filter 4 must be vented for maintenance and repair purposes.
- the container 1 can also via a vent line 7 via a vent tap 7a are vented, which is independent of the shut-off valve 5a and Control of the tightness of the hydraulic accumulator 2 is used.
- the ventilation of the hydraulic accumulator 2 can take place via a ventilation line 6 via a ventilation tap 6a.
- Extinguishing agent line 8 connected, which can be filled via a vent tap 8a and are connected to the sprinkler 9. Connected to the extinguishing agent line 8 are also a pressure switch 10 and a test port 11. In the extinguishing agent line a flow detector 12 is also integrated.
- the extinguishing liquid is pressed out of the hydraulic accumulator 2 into the extinguishing agent line 8 by means of the energy of the pressure cushion in the container 1, which is under approximately 10 bar operating pressure.
- the flow that begins with the extinguishing process of the sprinklers 9 in the extinguishing agent line 8 is detected by the flow detector 12 and reported as an alarm signal to the driver's console in the train driver's cab. If the pressure in the extinguishing agent line 8 drops to about 7 bar, the pressure switch 10 responds and reports on the driver's console Pressure deficiency disorder "the continued extinguishing agent removal.
- thermo-elastic plastic e.g. B. Polyethylene
- thermoelastic plastic it is expedient to make the liquid-carrying pipes from cross-linked, provide thermoelastic plastic.
