Definitions

  • the invention relates to a device for extinguishing a fire with in rooms of a building, in particular a building or a ship.
  • the supply line is at least partially filled in the rest position with pressurized extinguishing fluid.
  • the supply line or the extinguishing nozzles connected to the supply line are equipped with valves which prevent unwanted escape of extinguishing fluid in the rest position.
  • the valves open in case of fire automatically or remotely controlled by a control, so that extinguishing fluid can be discharged from the extinguishing nozzles.
  • the extinguishing nozzles may be formed in these systems such that the extinguishing nozzles are equipped with open nozzle inserts, which may be connected via channels formed in the extinguishing nozzles with the supply line.
  • These nozzle inserts can be designed such that they act upon exposure to a produce a extinguishing mist under high pressure extinguishing fluid.
  • An advantage of such a filled system is that the volume of the filled supply line is used for storing the extinguishing fluid.
  • the available storage energy and the capacity of the pressure vessels can be optimally utilized, in particular in systems in which the extinguishing fluid supply takes place via stored pressure energy. This makes it possible to use smaller pressure vessels, whereby a cost and space savings is achieved.
  • the filled systems offer the advantage that the time required for the unfilled systems for filling the supply line deleted.
  • the extinguishing fluid exits immediately after opening the valves, reducing the response time of the system to fire detection and preventing the fire from spreading further.
  • a disadvantage of the systems described above is the considerable manufacturing, assembly and maintenance costs for the valve devices used in these systems and the possibly necessary control of the valves.
  • the valves fail in case of fire, so that a fight against the fire is impossible.
  • the object of the invention is to provide a device of the type mentioned above with simple and inexpensive means that enables a safe response.
  • the supply lines are filled with extinguishing fluid.
  • the inflow of extinguishing fluid into the per se open extinguishing nozzles is closed in the rest state by a rupture disc, which is arranged in the region of the respective extinguishing nozzles associated terminal end of the connecting line.
  • a rupture disc which is arranged in the region of the respective extinguishing nozzles associated terminal end of the connecting line.
  • valves In addition, the reliability of the device is significantly increased by dispensing with valves and possibly necessary control of them.
  • the rupture disks used according to the invention can not settle. Since the use of rupture discs can be dispensed with a control, there is no longer a danger that this fails.
  • the nozzle inserts used in a device according to the invention generate an extinguishing mist.
  • an extinguishing mist With such an extinguishing mist, a fire with a small amount of extinguishing agent can be effectively combat.
  • the pressures required for the generation of such a mist of the Lösch proceedingsids are up to 300 bar.
  • the static pressure of the extinguishing fluid is equal to the ambient pressure. In this way, the effort required to maintain the static pressure, which is always necessary in the case of the known filled systems, can be avoided.
  • the quiescent pressure of the quenching fluid may be higher than the ambient pressure but lower than the bursting pressure.
  • a pressure drop and thus a leakage 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 leakage.
  • a plurality of extinguishing nozzles are connected to the connection end of the supply line via a branch piece.
  • the inflow of extinguishing fluid to more than one extinguishing nozzle is simultaneously closed by a rupture disk in the idle state. This is particularly useful when extinguishing nozzles in case of fire necessarily need to be applied simultaneously with extinguishing fluid to protect a particular object or a specific area section.
  • the extinguishing nozzles can each be connected via an intermediate line to the branch piece in order to ensure a flat or spatial coverage of a particular area.
  • the device 1 for extinguishing a fire has an extinguishing fluid supply 2, which comprises not shown in detail fluid container and a high-pressure pump.
  • the extinguishing fluid supply 2 may also be equipped with one or more pressure accumulators, in which extinguishing fluid is stored under pressure.
  • the extinguishing fluid can be stored under ambient pressure and pressurized only in the case of activation from one or more pressure accumulators.
  • the extinguishing fluid supply 2 is controlled by a control device 3, which receives the fire alarm signal of a fire alarm 4.
  • 7,8,9 extinguishing nozzles 10,11,12 are connected to the extinguishing fluid supply 2 via a main supply line 6 and their own supply lines branching off from the main supply line 6.
  • a first group 13 of three extinguishing nozzles 14 is connected via a branch piece 15 to a supply line 17 which leads away from a main supply line 16. Furthermore, a single extinguishing nozzle 18 is connected directly to a supply line 19, which also goes 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 the Main supply line 16 outgoing supply line 24 connected.
  • Each of the extinguishing nozzles 10,11,12,14,18,21 is constructed as the extinguishing nozzle 10 exemplified in Fig. 3
  • all extinguishing nozzles 10,11,12,14,18,21 open nozzle inserts 25, which in about the respective extinguishing nozzle formed channels 26 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 upon exposure to an extinguishing fluid under high pressure of up to 300 bar a finely distributing extinguishing mist.
  • the external thread 30 of paragraph 29 of the extinguishing nozzles 10,11,12,18 is screwed into a corresponding internal thread at the respective terminal end 7a, 8a, 9a of the supply lines 7,8,9 and 19, while the external thread 30 of paragraphs 29 of the extinguishing nozzles 14th are each screwed into a not shown corresponding internal thread at the respective terminal ends 15a of the branch piece 15. Accordingly, the extinguishing nozzles 21 are connected to the terminal end of their associated intermediate line 22.
  • the main supply line 6 (FIG. 1) or 16 (FIG. 2) and supply lines 7, 8, 9 (FIG. 1) and 17, 19, 24 (FIG. with extinguishing liquid, for example water, filled. It prevails in the from the main supply line 6 and 16 and the outgoing from her supply lines 7,8,9 and 17,19,24 formed, filled with extinguishing fluid piping system a static pressure that corresponds approximately to the ambient pressure.
  • the fire guard 4 monitors a room, a certain area or a specific object on the emergence of a fire. With the emergence of a fire, the fire alarm 4 gives a fire alarm signal to the controller 3. This then causes the extinguishing fluid supply 2, the main supply line 6 and 16 and the respective outgoing supply lines 7,8,9 and 17,19,24 with Pressed extinguishing fluid applied.
