Abschlussvorrichtung für einen BrandabschnittTermination device for a fire compartment
Die Erfindung bezieht sich auf eine Abschlussvorrichtung für einen Brandabschnitt mit einer ein Abschlussmittel in Abhängigkeit von einer Flutung mit Löschgas steuernden Betätigungsvorrichtung, die ein Antriebsmittel zum Öffnen und Offenhalten des Abschlussmittels bei anstehendem Löschgasdruck aufweist.The invention relates to a closing device for a fire compartment with an actuating device which controls a closing means as a function of flooding with extinguishing gas and which has a drive means for opening and keeping the closing means open when the extinguishing gas pressure is present.
Üblicherweise weist eine derartige Abschlussvorrichtung für einen Brandabschnitt bzw. brandschutzsichere Zelle zum Steuern eines Abschlussmittels, z.B. in Form eines Schiebers, in Abhängigkeit von einer Flutung mit Löschgas eine Betätigungsvorrichtung mit einem elektromotorischen Antrieb auf, der das Abschlussmittel öff- net, wenn die Zelle mit Löschgas geflutet wird. Auf diese Weise wird verhindert, dass in dem Brandabschnitt bzw. der Zelle ein zu hoher Druck entsteht und gleichzeitig wird bewirkt, dass die Sauerstoffkonzentration auf einen bestimmten Wert reduziert wird. Dabei ist es schwierig, das Öffnen und/oder Schließen des Abschlussmittels in Abhängigkeit von der Löschgasmenge optimal zu steuern, ins- besondere wenn unterschiedlichen Löschgasen Rechnung getragen werden soll. Bei einer in der JP 2001 -204 836 A angegebenen Abschlussvorrichtung wird ein Rauchschieber mittels eines Zusatzaggregates gesteuert, das seinerseits über eineSuch a termination device for a fire section or fire-proof cell for controlling a closure means, for example in the form of a slide, has, depending on flooding with extinguishing gas, an actuating device with an electromotive drive which opens the closure means when the cell with extinguishing gas is flooded. In this way it is prevented that too high a pressure arises in the fire compartment or the cell and at the same time it is caused that the oxygen concentration is reduced to a certain value. It is difficult to optimally control the opening and / or closing of the closing means depending on the amount of extinguishing gas, especially when different extinguishing gases are to be taken into account. In a termination device specified in JP 2001-204 836 A, a smoke valve is controlled by means of an additional unit, which in turn is controlled by a
Ventilanordnung an das Loschgasleitungssystem angeschlossen ist.Valve arrangement is connected to the extinguishing gas line system.
Die JP 1 1 -125 456 A zeigt eine Abschlussvorrichtung, bei der eine Schieberanordnung nach Auslösung durch eine Temperatursicherung mittels einer Antriebsvorrichtung aus einer Offenstellung in eine Schließstellung gebracht wird. Bei Ansteigen des Löschgasdruckes wird die Schieberanordnung gegen eine Gewichtskraft geöffnet.JP 1 1 -125 456 A shows a termination device in which a slide arrangement is brought out of an open position into a closed position after being triggered by a temperature fuse by means of a drive device. When the extinguishing gas pressure rises, the slide arrangement is opened against a weight force.
Auch bei derartigen Lösungen ist es schwierig, die Schieberanordnung bei einer Löschgaszufuhr optimal zu steuern.Even with such solutions, it is difficult to optimally control the slide arrangement when supplying extinguishing gas.
Der Erfindung liegt die Aufgabe zugrunde, eine Abschlussvorrichtung der eingangs genannten Art bereit zu stellen, die eine möglichst wirkungsvolle Betätigung des Abschlussmittels in Abhängigkeit einer Flutung mit Löschgas ergibt.The invention has for its object to provide a closure device of the type mentioned, which results in the most effective actuation of the closure means depending on a flooding with extinguishing gas.
Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Dabei ist vorge- dass die Betätigungsvorrichtung pneumatisch in Abhängigkeit von in einem ι_<jöungasleitungssystem herrschenden Löschgasdruck angesteuert ist und das Offenhalten des Abschlussmittels sicherstellt, solange der Löschgasdruck einen vorgegebenen oder vorgebbaren Schwellenwert überschreitet. Die Zuverlässigkeit der Funktion wird dadurch gesteigert, dass die Betätigungs- Vorrichtung zusätzlich ein weiteres Antriebsmittel aufweist, das pneumatisch in Abhängigkeit von dem Löschgasdruck ansteuerbar ist.The object is achieved with the features of claim 1. The actuating device is controlled pneumatically as a function of the extinguishing gas pressure prevailing in a junction gas line system and ensures that the closing means is kept open as long as the extinguishing gas pressure exceeds a predetermined or predeterminable threshold value. The reliability of the function is increased in that the actuating device additionally has a further drive means which can be controlled pneumatically as a function of the extinguishing gas pressure.
Das weitere Antriebsmittel bildet einen redundanten Antrieb, der zusätzlich zu dem üblicherweise vorhandenen Antriebsmittel, insbesondere einem Elektromotor, zum Steuern des Abschlussmittels vorhanden ist. Da das weitere Antriebsmittel pneumatisch in Abhängigkeit von dem in dem Loschgasleitungssystem herrschenden Löschgasdruck bzw. der dort vorliegenden Löschgasströmung angesteuert ist, kann genau und sicher festgestellt werden, ob eine Flutung mit Löschgas vorliegt. Dadurch wird eine definierte Betätigung des Abschlussmittels sichergestellt.The further drive means forms a redundant drive, which is provided in addition to the drive means usually present, in particular an electric motor, for controlling the closing means. Since the further drive means is controlled pneumatically as a function of the extinguishing gas pressure prevailing in the extinguishing gas line system or the extinguishing gas flow there, it can be determined precisely and reliably whether there is flooding with extinguishing gas. This ensures a defined actuation of the closing means.
Eine vorteilhafte Ausgestaltung besteht darin, dass das weitere Antriebsmittel als pneumatisches Antriebsmittel ausgebildet ist und zu seiner Betätigung mit dem Loschgasleitungssystem unmittelbar in Verbindung steht. Hierbei wird das weitere Antriebsmittel unmittelbar durch das Löschgas in dem Loschgasleitungssystem ge- steuert. Es bildet dabei gleichzeitig eine Sensor-/ und Aktoreinrichtung.An advantageous embodiment is that the further drive means is designed as a pneumatic drive means and is directly connected to the extinguishing gas line system for its actuation. Here, the further drive means is controlled directly by the extinguishing gas in the extinguishing gas line system. It simultaneously forms a sensor and actuator device.
Ist ferner vorgesehen, dass das weitere Antriebsmittel zum redundanten Aufsteuern des Abschlussmittels ausgebildet ist, und/oder in Kombination mit dem Antriebsmittel betreibbar ist, kann das weitere Antriebsmittel beispielsweise bei Ausfall oder einem Fehler des üblicherweise vorhandenen Antriebsmittels, insbesondere Elektroantriebs, auch das Aufsteuern des Abschlussmittels übernehmen.If it is further provided that the further drive means is designed for redundant actuation of the closure means and / or can be operated in combination with the drive means, the further drive means can also, for example in the event of a failure or a fault in the drive means usually present, in particular an electric drive, actuate the closure means take.
Das weitere Antriebsmittel kann auch als alleiniges Antriebsmittel des Abschlussmittels eingesetzt werden. Die Sicherheit der Abschlussvorrichtung wird weiterhin dadurch unterstützt, dass ein mechanisch und fremdenergieunabhängig arbeitendes Schließsystem für das Abschlussmittel vorgesehen ist, und dass das weitere Antriebsmittel oder eine ebenfalls in Abhängigkeit von dem anstehenden Löschgasdruck gesteuerte Blockiereinrichtung derart ausgebildet ist, dass es oder sie zum Offenhalten des Abschlussmittels direkt auf die Betätigungsvorrichtung oder blockierend auf das Schließsystem wirkt. Insbesondere ist auch eine derartige Blockiereinrichtung sicher und eindeutig in Abhängigkeit von einem Flutungszustand mit Löschgas steuerbar.The further drive means can also be used as the sole drive means of the closing means. The security of the locking device is further supported by the fact that a locking system that works mechanically and independently of external energy is provided for the locking means and that the further drive means or a blocking device that is also controlled as a function of the pending extinguishing gas pressure is designed such that it or it keeps the locking means open acts directly on the actuating device or blocks the locking system. In particular, such a blocking device can also be controlled safely and unambiguously with extinguishing gas as a function of a flooding condition.
Die Einhaltung eines Schließkriteriums wird dadurch sicher erreicht, dass das Schließsystem bei Unterschreiten des Schwellenwertes zum Schließen des Abschlussmittels freigegeben wird.Adherence to a closing criterion is reliably achieved in that the locking system is released for closing the closing means when the threshold value is undershot.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen näher erläuert. Es zeigen:The invention is explained below using an exemplary embodiment with reference to the drawings. Show it:

Das weitere Antriebsmittel 1 1 .3 sowie die Blockiervorrichtung 1 1 .2 sind an die Zuführleitung 21 über eine Verbindung 22.1 bzw. eine weitere Verbindung 22.2 vorzugsweise unmittelbar angeschlossen. Das Löschgas wird über (nicht gezeigte) Düsen in die Zelle eingeleitet. In Abhängigkeit von dem verwendeten Löschgas und gegebenenfalls anderen konstruktiven Eigenschaften können die Düsen-Überdrucke stark unterschiedlich sein.Fig. 2 to 5 different representations in particular of the actuating device of the termination device. A closure device 1 shown in FIG. 1 for a fire section or a fire-proof cell, for example a fire-proof room or IT cabinet, has an extinguishing gas line system 20 which leads to the area of the fire section and has a feed line 21 for extinguishing gas and further comprises closing means 10 in the form at least one slide, which are actuated via an actuating device 1 1 with a drive means 1 1 .1, for example an electric drive, a further drive means 1 1 .3, and a blocking device 1 1 .2 as a function of flooding with extinguishing gas. The further drive means 1 1 .3 and the blocking device 1 1 .2 are preferably connected directly to the feed line 21 via a connection 22.1 or a further connection 22.2. The extinguishing gas is introduced into the cell via nozzles (not shown). Depending on the extinguishing gas used and possibly other design properties, the nozzle overpressures can vary widely.

Durch den Anschluss an das Loschgasleitungssystem 20 sprechen das weitere Antriebsmittel 1 1 .3, z.B. ein Zylinder oder Pneumatikmotor, sowie die Blockier- Vorrichtung 1 1 .2 sehr genau auf einen vorhandenen Löschgasdruck bzw. eine Löschgasströmung an, so dass eine sicher und definiert arbeitende Ansteuerung des oder der Schieber 10 erhalten wird, die allein oder redundant zu dem Antriebsmittel 1 1 .1 bzw. in Kombination mit diesem betrieben werden kann. Das Öffnen und Schließen erfolgen mit dem Löschgas selbst. Dabei ist auch denkbar, auf das Antriebsmittel 1 1 .1 zu verzichten.By connecting to the extinguishing gas line system 20, the further drive means 1 1 .3, for example a cylinder or pneumatic motor, as well as the blocking device 1 1 .2 respond very precisely to an existing extinguishing gas pressure or an extinguishing gas flow, so that one that works safely and in a defined manner Control of the slider or slides 10 is obtained, which can be operated alone or redundantly to the drive means 1 1 .1 or in combination with this. The The extinguishing gas itself opens and closes. It is also conceivable to dispense with the drive means 1 1 .1.
Das weitere, pneumatisch arbeitende Antriebsmittel 1 1 .3 kann dabei so ausgebildet sein, dass es den mit dem Antriebsmittel 1 1 .1 geöffneten Schieber 10 auch bei einem Ausfall oder Funktionsabfall des Antriebsmittels 1 1 .1 offen hält. Zusätzlich kann vorgesehen sein, dass mittels des weiteren Antriebsmittels 1 1 .3 der Schieber 10 auch aufgesteuert werden kann. Da das weitere Antriebsmittel 1 1 .3 unmittelbar oder definiert mittelbar mit dem Loschgasleitungssystem 20 verbunden ist, kann leicht mindestens eine mit einem Sensor erfassbare Druckschwelle von z.B. höchstens 0, 1 bar, höchstens 0,05 bar oder gar höchstens 0,03 bar vorgegeben werden, oberhalb der der Schieber 10 geöffnet bzw. offen gehalten wird und unterhalb der ein weiterhin noch vorhandenes Schließsystem freigegeben wird, das vorteilhaft z.B. mechanisch und dabei fremdenergieunabhängig arbeitet, wie z.B. ein mechanisches Federsystem 1 1 .5, das beim Öffnen des Schiebers 10 gespannt wird, oder ein mit Schwerkraft betätigtes System. Da das Löschgas selbst zum Betreiben des weiteren Antriebsmittels 1 1 .3 verwendet wird, lässt sich eine sehr genau von dem Löschgasdruck abhängige Steuerung des Schiebers 10 erreichen.The further, pneumatically operating drive means 1 1 .3 can be designed so that it keeps the slide 10 opened with the drive means 1 1 .1 open even in the event of a failure or functional loss of the drive means 1 1 .1. In addition, it can be provided that the slide 10 can also be opened by means of the further drive means 11.3. Since the further drive means 11.3 is directly or indirectly indirectly connected to the extinguishing gas line system 20, at least one pressure threshold of e.g. a maximum of 0.1 bar, a maximum of 0.05 bar or even a maximum of 0.03 bar above which the slide 10 is kept open or open and below which a locking system which is still present is released, which advantageously is e.g. works mechanically and independently of external energy, e.g. a mechanical spring system 1 1 .5, which is tensioned when the slide 10 opens, or a system operated by gravity. Since the extinguishing gas itself is used to operate the further drive means 1 1 .3, the slide 10 can be controlled very precisely depending on the extinguishing gas pressure.
Die Blockiervorrichtung 1 1 .2, die ebenfalls an das Loschgasleitungssystem 20 angeschlossen ist und mit Freilauf in Richtung Auf-Stellung des Schiebers 10 versehen ist, kann ebenfalls in Abhängigkeit von mindestens einer genau vorgebbaren Druckschwelle des Löschgases von z.B. höchstens 0, 1 bar, höchstens 0,05 bar oder höchstens 0,03 bar die Freigabe des Schiebers 10 steuern, so dass dieser über das Schließsystem zugesteuert werden kann. Dabei kann die Blockiervorrich- tung 1 1 .2 entweder auf das Antriebsmittel 1 1.1 und/oder das weitere Antriebs- mittel 1 1 .3 oder aber auf das Schließsystem wirken, um das Schließen des Schiebers 10 auszulösen. Entsprechend kann bei einem Fehlen der Blockiervorrichtung 1 1 .2 das weitere Antriebsmittel 1 1 .3 ausgebildet sein, um die Blockierfunktion zu übernehmen. Die Blockiervorrichtung 1 1 .2 weist einen Blockiermechanismus mit einem verstellbaren Blockierelement auf, das beispielsweise als Bremsband oder Bremsscheide ausgebildet ist. Die Verstellung erfolgt vorteilhaft mittels eines von von dem Löschgas betätigten separaten Zylinders. Die Druckschwelle kann in Abhängigkeit von der Art des Löschgases vorgebbar sein. Auch über die Betätigung der Blockiervorrichtung 1 1 .2 durch das Löschgas lässt sich eine sehr genaue Steuerung des Schiebers 10 in Abhängigkeit von der aktuellen Flutung des Raumes mit dem Löschgas erreichen.The blocking device 1 1 .2, which is also connected to the extinguishing gas line system 20 and is provided with a freewheel in the direction of the open position of the slide 10, can also, depending on at least one precisely definable pressure threshold of the extinguishing gas, for example at most 0.1 bar, at most 0.05 bar or at most 0.03 bar control the release of the slide 10 so that it can be controlled via the locking system. The blocking device can device 1 1 .2 either act on the drive means 1 1.1 and / or the further drive means 1 1 .3 or else on the locking system in order to trigger the closing of the slide 10. Accordingly, in the absence of the blocking device 1 1 .2, the further drive means 1 1 .3 can be designed to take over the blocking function. The blocking device 1 1 .2 has a blocking mechanism with an adjustable blocking element, which is designed, for example, as a brake band or brake sheath. The adjustment is advantageously carried out by means of a separate cylinder operated by the extinguishing gas. The pressure threshold can be predefined depending on the type of extinguishing gas. A very precise control of the slide 10 as a function of the current flooding of the space with the extinguishing gas can also be achieved by actuating the blocking device 1 1 .2 by the extinguishing gas.
Der Blockiervorrichtung 1 1 .2 ist ein gesonderter Steuerkreis zugeordnet, mit dem die Offenhaltefunktion des Schiebers 10 gesteuert bzw. geregelt wird. Mit einem dem oder den Antriebsmitteln 1 1 .1 , 1 1 .3 zugeordneten Antriebskreis wird hinge- gen der Schieber 10 bewegt und das mechanische Schließsystem 1 1 .5 aufgezogen. Vorteilhaft sind Antriebskreis und Steuerkreis getrennt.The blocking device 1 1 .2 is assigned a separate control circuit with which the hold-open function of the slide 10 is controlled or regulated.
