Definitions
- the invention relates to a device for extinguishing a fire with extinguishing nozzles arranged in rooms of a building, in particular a building or a ship, which are each connected to a connection end of a supply line filled with extinguishing fluid, which connects the extinguishing nozzles to an extinguishing fluid supply which, in the event of a fire Pressurized extinguishing fluid is supplied to the supply line.
- the supply line is at least partially filled with pressurized extinguishing fluid in the rest position.
- the supply line or the extinguishing nozzles connected to the supply line are equipped with valves which prevent an undesired escape of extinguishing fluid in the idle position. In the event of a fire, the valves open automatically or by remote control so that extinguishing fluid can be discharged from the extinguishing nozzles.
- the extinguishing nozzles can be designed such that the extinguishing nozzles are equipped with open nozzle inserts which can be connected to the supply line via channels formed in the extinguishing nozzles.
- These nozzle inserts can be designed such that they are loaded with a create an extinguishing mist under high pressure.
- the volume of the filled supply line is used to store the extinguishing fluid.
- the available storage energy and the capacity of the pressure vessels can be optimally used. This makes it possible to use smaller pressure vessels, which saves costs and space.
- the filled systems offer the advantage that the time required for filling the supply line in the unfilled systems is eliminated.
- the extinguishing fluid escapes immediately after opening the valves, which shortens the response time of the system to a fire message and prevents the fire from spreading further.
- the object of the invention is to provide a device of the type mentioned at the beginning with simple and inexpensive means, which enables a reliable response.
- a rupture disk is arranged in the region of the connection end of the supply line, which bursts when the extinguishing fluid in the supply line reaches a predetermined burst pressure, so that extinguishing fluid flows unhindered into the extinguishing nozzle, and that Supply line in the rest position of the device is filled with extinguishing fluid at a resting pressure which is less than the bursting pressure.
- the supply lines are filled with extinguishing fluid.
- the inflow of extinguishing fluid into the extinguishing nozzles, which are open per se, is closed in the idle state by a rupture disk which is arranged in the region of the connection end of the connecting line assigned to the respective extinguishing nozzles.
- the invention takes advantage of a filled fire-fighting system and also enables the device to be reliably activated. So instructs Fire-fighting system designed according to the invention has short reaction times, since extinguishing fluid is already in the immediate vicinity of the extinguishing nozzles and the distance to be covered by the liquid to the nozzles is short.
- valves By dispensing with valves and possibly triggering them, the reliability of the device is significantly increased.
- the rupture disks used according to the invention cannot get stuck. Since control can also be dispensed with when using rupture disks, there is no longer any danger that this will fail.
- the nozzle inserts used in a device according to the invention preferably produce an extinguishing mist.
- an extinguishing mist With such an extinguishing mist, a fire can be effectively combated with a small amount of extinguishing agent.
- the pressures of the extinguishing fluid required to generate such a mist are up to 300 bar.
- the quiescent pressure of the extinguishing fluid is preferably equal to the ambient pressure. In this way, the effort required to maintain the resting pressure, which is always required in the known filled systems, can be avoided.
- the quiescent pressure of the extinguishing fluid can be higher than the ambient pressure but lower than the bursting pressure.
- a pressure drop and thus a leak in the filled supply line can be detected via a pressure sensor arranged in the filled supply line, which detects the pressure drop in the supply line associated with a leak.
- extinguishing nozzles are connected to the connection end of the supply line via a branching piece.
- the inflow of extinguishing fluid to more than one extinguishing nozzle is closed at the same time by a rupture disk.
- extinguishing nozzles in the event of a fire necessarily have to be supplied with extinguishing fluid simultaneously to protect a specific object or a specific surface section.
- the extinguishing nozzles can each be connected to the branching piece via an intermediate line in order to be able to guarantee a flat or spatial coverage of a specific area.
- Figure 1 shows a device for extinguishing a fire in a schematic representation.
- FIG. 2 shows a variant of the device according to FIG. 1;
- Fig. 3 in one of the devices according to the
- Figures 1 or 2 used extinguishing nozzle in a partially broken side view.
- the device 1 for extinguishing a fire has an extinguishing fluid supply 2 which comprises fluid containers (not shown in detail) and a high-pressure pump.
- the extinguishing fluid supply 2 can also be equipped with one or more pressure reservoirs in which extinguishing fluid is stored under pressure.
- the extinguishing fluid can be stored under ambient pressure and can only be pressurized from one or more pressure reservoirs when activated.
- the extinguishing fluid supply 2 is controlled by a control device 3, which receives the fire alarm signal from a fire guard 4.
- main supply line 6 there are a main supply line 6 and separate lines branching from the main supply line 6
- a first group 13 of three extinguishing nozzles 14 is connected to one of one via a branching piece 15
- Main supply line 16 outgoing supply line 17 connected. Furthermore, a single extinguishing nozzle 18 is connected directly to a supply line 19, which also branches off from the main supply line 16. In a third group 20 of three extinguishing nozzles 21, the extinguishing nozzles 21 are finally via intermediate lines 22 and a branch piece 23 to a third, of which Main supply line 16 outgoing supply line 24 connected.
- Each of the extinguishing nozzles 10, 11, 12, 14, 18, 21 is constructed like the extinguishing nozzle 10 shown by way of example in FIG. 3.
- all of the extinguishing nozzles 10, 11, 12, 14, 18, 21 have open nozzle inserts 25, which are arranged in channels 26 of the respective extinguishing nozzle are connected to an inflow bore 27 of the extinguishing nozzle.
- the inflow bore 27 opens onto the end face of a shoulder 29, which is provided with an external thread 30.
- the nozzle inserts 25 generate a finely distributed extinguishing mist when exposed to an extinguishing fluid under high pressure of up to 300 bar.
- the external thread 30 of the shoulder 29 of the extinguishing nozzles 10, 11, 12, 18 is screwed into a corresponding internal thread at the respective connection end 7a, 8a, 9a of the supply lines 7, 8, 9 and 19, respectively, while the external thread 30 of the shoulders 29 of the extinguishing nozzle 14 are each screwed into a corresponding internal thread, not shown here, on the respective connection ends 15a of the branching piece 15. Accordingly, the extinguishing nozzles 21 are connected to the connection end of the intermediate line 22 assigned to them.
- the main supply line 6 (FIG. 1) or 16 (FIG. 2) and supply lines 7, 8, 9 (FIG. 1) or 17, 19, 24 (FIG. 2) coming from it are filled with extinguishing liquid, for example water.
- extinguishing liquid for example water.
- the fire guard 4 monitors a room, a certain area or a certain object for the occurrence of a fire. When a fire arises, the fire monitor 4 sends a fire alarm signal to the control device 3, which then causes the extinguishing fluid supply 2 to supply the main supply line 6 or 16 and that which goes out from it
- Supply lines 7, 8, 9 or 17, 19, 24 are pressurized with pressurized extinguishing fluid.
- a rupture disk can also be arranged directly in front of the individual extinguishing nozzles 15 and 21 in the case of the extinguishing nozzles 14, 21 of groups 13 and 15 in the exemplary embodiment according to FIG. 2.
- the embodiment described here is always useful if the distance between the extinguishing nozzles 14, 21 is short in each case compared to the other line lengths, so that on the one hand the effort for the assembly of the rupture disc is minimized and on the other hand the time for filling the at rest empty junction pieces and intermediate lines is short.
