Abstract

A sprinkler system for rail vehicles (SFZ) with at least one liquid container (FBH), which can be connected via a pressure medium line (DML) with a pressure medium container (DMB) and which can be placed under pressure, and with a number of thermally triggerable sprinkler nozzles (SDF, SDD) that are connected with the liquid container via a liquid line (FLL), where in the pressure medium line (DML) between the pressure medium container (DMB) and the liquid container (FBH), there is connected an electromechanical alarm valve (AVE) that is controlled by a fire alarm system (BMA), which alarm valve is closed during routine operation but which is opened in case of an alarm, so that in case of an alarm, the liquid container (FBH) and the liquid line (FLL) leading to the sprinkler nozzles will be pressurized.

Claims

1. A sprinkler system for rail vehicles with at least one liquid container, which via a pressure medium line can be connected with a pressure medium container and which can be placed under pressure and with a number of thermally triggerable sprinkler nozzles that are connected with the liquid container via a liquid line, characterized in that:

in the pressure medium line between the pressure medium tank and the liquid container, there is connected an electromechanical alarm valve that is controlled by a fire alarm system, which is closed during routine operation but which is open in case of an alarm, so that in case of an alarm, the liquid container and the liquid line leading to the sprinkler nozzles will be pressurized.

2. The sprinkler system according to claim 1, characterized in that the pressure medium container is connected via at least one return valve to the pressure medium supply of the rail vehicle.

3. The sprinkler system according to claim 2, characterized in that a manually and electrically operable feed, shutoff and ventilation exhaust valve is positioned between the return valve and the pressure medium container.

4. The sprinkler system according to claim 3, characterized in that the liquid line is connected via a return valve to a lower dry fire-extinguishing line with an outside connection.

5. The sprinkler system according to claim 2, characterized in that the liquid line is connected via a return valve to a lower dry fire-extinguishing line with an outside connection.

6. The sprinkler system according to claim 1, characterized in that the liquid line is connected via a return valve to a lower dry fire-extinguishing line with an outside connection.

7. The sprinkler system according to claim 6, characterized in that the liquid line leads both to the sprinkler nozzles for the ceiling filler space of the vehicle and to the sprinkler nozzles for the passenger compartment or internal compartment.

8. The sprinkler system according to claim 7, characterized in that the sprinkler nozzles for segments of the rail vehicle, for example, for the ceiling filler space, can be triggered at temperatures higher than the sprinkler nozzles for the passenger compartment or interior compartment.

9. The sprinkler system according to claim 1, characterized in that the liquid line leads both to the sprinkler nozzles for the ceiling filler space of the vehicle and to the sprinkler nozzles for the passenger compartment or internal compartment.

10. The sprinkler system according to claim 9, characterized in that the sprinkler nozzles for segments of the rail vehicle, for example, for the ceiling filler space, can be triggered at temperatures higher than the sprinkler nozzles for the passenger compartment or interior compartment.

11. The sprinkler system according to claim 1, characterized in that the sprinkler nozzles for segments of the rail vehicle, for example, for the ceiling filler space, can be triggered at temperatures higher than the sprinkler nozzles for the passenger compartment or interior compartment.
