Definitions
- the invention relates to a device for deleting Fire using an extinguishing fluid with the extinguishing fluid leading supply line, which is a pump with a
- a plurality of extinguishing nozzle heads connects, each have at least one extinguishing nozzle which over at least one connection channel with the Supply line is connected, and with a Fire guard device, which in the event of a fire Release of extinguishing fluid from the extinguishing nozzles where at least one of the extinguishing nozzle heads Extinguishing fluid escapes from at least one of the Extinguishing nozzles by means of themselves when a Minimum pressure of the extinguishing fluid that opens automatically Closure device is closed.
- Such Fire extinguishers are stationary in a building or mounted on a ship.
- the Invention an extinguishing nozzle head for a device for Extinguishing fire of the aforementioned kind.
- Known fire extinguishers are usually included a pressure generator, for example a pump, for Generate the extinguishing fluid pressure required for extinguishing and arranged in the rooms at risk of fire Extinguishing nozzles equipped which Supply line system connected to the pressure generator are.
- a pressure generator for example a pump
- the escape of Extinguishing fluid from the extinguishing nozzles through a Fire detection device triggered by each of the Extinguishing nozzles is assigned.
- extinguishing nozzle head of the type mentioned is from the Publication of PCT application WO-A-94/16771 known.
- the known extinguishing nozzle head is Connection channel through which the extinguishing nozzle to the Supply line is connected, in the idle state closed by a piston.
- This piston is over a coil spring on one usually in such Extinguishing nozzle heads used as fire guards Glass bottle supported.
- the well-known extinguishing nozzle head enables considerable Simplification in the design and control of Fire extinguishers in which a plurality of Extinguishing nozzle heads depending on the location of the fire must be opened.
- the known extinguishing nozzle head due to the narrow Tolerance limits, within the spring and the piston must be designed and moved as prone to failure.
- the object of the invention is to use simple, cost-effective means the reliability of a Fire extinguishing device of the type mentioned and one used in such a device To improve the extinguishing nozzle head.
- This task is related to the erasing device a fire solved according to the invention in that each of the Extinguishing nozzles of the extinguishing nozzle head over at least two Connection channels connected to the supply line is, wherein one of the connection channels in the idle state through which a minimum pressure of the First closure device opening extinguishing fluids is closed and the other of the connecting channels in the Idle state by a second locking device is closed, which in the event of fire by the Fire guard device can be opened.
- this task solved that the at least one extinguishing nozzle of the Extinguishing nozzle head via at least two connecting channels the supply line is connected, the one of the connection channels in the idle state through which Exceeding a minimum pressure of the extinguishing fluid opening first closure device is closed and the other the connection channels in the idle state by a second Closure device is closed, which with the Fire detection device is coupled such that the Fire guard device opening in case of fire the second closure device.
- the leakage of Extinguishing fluid from the extinguishing nozzle head can only be brought about by the fact that for example, on a corresponding signal Fire guard device with the extinguishing nozzle head connected pressure generator is switched on. After this Switching on the pump increases the pressure within the Supply system. If one is exceeded certain limit pressure opens automatically appealing when the minimum pressure is exceeded Locking device.
- the fire guard device a through Heat destructible element on which a movable valve piston is spring-loaded, which can be opened by the fire guard device Closing device forms.
- the fire guard facility and the relevant one Locking device in a simple way Requires a very small installation space realize. This is especially true if that Element that can be destroyed by heat Glass bottle is.
- the invention can be particularly advantageous Insert the extinguishing nozzle head when the extinguishing nozzles are out create an extinguishing mist on the extinguishing fluid. Using an extinguishing mist formed from an extinguishing fluid extinguish a fire with a minimum of extinguishing fluid.
- the cost of an erase head according to the invention can be at the same time high operational reliability and robustness are kept particularly low in that the opening by increasing the pressure of the extinguishing fluid Closure device formed by a rupture disc is.
- Such rupture discs can be replaced by an appropriate one Choice of materials and by choosing an appropriate one Sizing to the respective in a simple manner Operating conditions are adjusted.
- the Pressure increase of the extinguishing fluid opening Closure device than by an elastic Restoring force loaded, movable valve body be formed, which is at least a first Has pressure area on which the fluid in a essentially directed against the restoring force Exerts pressure.
- This embodiment of the invention can be used particularly advantageously when the Connection channel in a the first pressure area surrounding chamber opens and if over a section the first pressure surface opens into the chamber Connection channel is closable.
- by a single movement of the Valve body at least one of the connecting channels openable and at least one more of the Connection channels can be closed. In both cases it is possible depending on that in the Supply line pressure prevailing the exit of Control extinguishing fluid from different nozzles. This is particularly advantageous if the invention Extinguishing device with extinguishing fluid mist used because in this case the composition of the Extinguishing mist can be controlled in a simple manner can.
