Description

Die Erfindung betrifft einen Grundkörper einer Feuerlöscher-Zentralarmatur, welcher aus Kunststoff besteht, mit einem Löschmitteltank fest verbindbar ist und eine Anzahl weiterer Anschlüsse aufweist.The invention relates to a main body of a fire extinguisher central armature, which consists of plastic, with an extinguishing agent tank is firmly connected and has a number of other connections.

Grundkörper für Feuerlöscher-Zentralarmaturen sind üblicherweise aus Metall, beispielsweise aus Messing oder Aluminium, hergestellt. In der Patentliteratur, beispielsweise der DE-A-26 59 113 und der DE-U-69 17 885 , ist als Material für den Grundkörper Kunststoff erwähnt. In die Praxis haben sich die bislang eingesetzten Kunststoffe als ungeeignet erwiesen, insbesondere wegen mangelhafter Chemikalienbeständigkeit und zu hoher Wasseraufnahme und der damit verbundenen Änderung der mechanischen Materialeigenschaften.Basic body for central fire extinguishers are usually made of metal, such as brass or aluminum. In the patent literature, for example the DE-A-26 59 113 and the DE-U-69 17 885 , is mentioned as a material for the main body plastic. In practice, the plastics used hitherto have proven unsuitable, in particular because of poor chemical resistance and high water absorption and the associated change in the mechanical properties of the material.

Der Erfindung liegt die Aufgabe zugrunde, ein Kunststoffmaterial für den Grundkörper einer Zentralarmatur eines Feuerlöschers zur Verfügung zu stellen, welches obige Nachteile nicht aufweist.The invention has for its object to provide a plastic material for the body of a central valve of a fire extinguisher available, which does not have the above disadvantages.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass der Kunststoff ein glasfaserverstärktes, teilaromatisches Polyamid ist.The object is achieved according to the invention in that the plastic is a glass fiber reinforced, partly aromatic polyamide.

Dieses Material zeichnet sich durch eine gute Chemikalienbeständigkeit, eine hohe Zähigkeit und Festigkeit und eine äußerst geringe Wasseraufnahme aus und ist daher als Material für den Grundkörper hervorragend geeignet.This material is characterized by a good chemical resistance, a high toughness and strength and an extremely low water absorption and is therefore ideal as a material for the base body.

An einem Grundkörper aus einem derartigen Material lässt sich auf einfache Weise eine Sollberststelle integrieren, indem diese von einer lokalen Materialschwächung bzw. einer lokalen Reduktion der Wandstärke des Grundkörpers gebildet wird. Durch diese Maßnahme wird sichergestellt, dass sich ein im Tankinneren einstellender Überdruck rechtzeitig durch Aufbrechen der Sollberststelle gezielt abbauen lässt. Beschädigungen an Gegenständen und Verletzungen von Personen sind somit wirkungsvoll verhindert.On a basic body made of such a material, a desired bursting point can be integrated in a simple manner by forming it from a local material weakening or a local reduction of the wall thickness of the basic body. This measure ensures that an overpressure occurring in the interior of the tank can be deliberately reduced in a timely manner by breaking up the predetermined bursting point. Damage to objects and injuries to persons are thus effectively prevented.

Bei einer bevorzugten Ausführungsform der Erfindung ist die Sollberststelle durch eine lokale Vertiefung, an deren Boden eine Rille vorgesehen ist, gebildet. Die Rille definiert die lokale Materialschwächung, welche bei zu hohem Innendruck im Löschmitteltank aufgeht.In a preferred embodiment of the invention, the predetermined bursting point is formed by a local depression, at the bottom of which a groove is provided. The groove defines the local weakening of the material which occurs in the extinguishing agent tank if the internal pressure in the tank is too high.

Die Erfindung betrifft ferner eine Feuerlöscher-Zentralarmatur, welche einen Grundkörper mit obigen Merkmalen aufweist.The invention further relates to a fire extinguisher central armature, which has a base body with the above features.

Die Figuren zeigen eine Zentralarmatur für einen Aufladefeuerlöscher, bei welchem ein unter Druck stehendes Treibmittel, beispielsweise Kohlendioxid oder Stickstoff, in einer Druckpatrone 11 untergebracht ist, die sich im Hauptbehälter, dem Löschmitteltank 10, befindet. Als Löschmittel für solche Feuerlöscher kommen Flüssigkeiten, wie Wasser oder Schaummittel, aber auch Löschpulver in Betracht. Der Löschmitteltank 10 und die Druckpatrone 11 sind in Fig. 2, 4 und 5 angedeutet und es wird auf diese Bestandteile des Feuerlöschers in der nachfolgenden Beschreibung nur insoweit Bezug genommen, als es für das Verständnis der Erfindung erforderlich ist.The figures show a central armature for a Aufladefeuerlöscher, in which a pressurized propellant, such as carbon dioxide or nitrogen, is housed in a print cartridge 11, which is located in the main tank, the extinguishing agent tank 10. Suitable extinguishing agents for such fire extinguishers are liquids, such as water or foaming agents, but also extinguishing powder. The extinguishing agent tank 10 and the print cartridge 11 are in Fig. 2 . 4 and 5 is indicated and reference is made to these components of the fire extinguisher in the following description only insofar as it is necessary for the understanding of the invention.

Die Zentralarmatur weist einen Grundkörper 1 auf, welcher mittels eines Anschlussringes 2 mit dem Löschmitteltank 10 fest verbunden wird. An der in den Löschmitteltank 10 ragenden Unterseite der Zentralarmatur ist am Grundkörper 1 ein Adapter 3 aufgeschraubt, an welchen die im Löschmitteltank 10 untergebrachte Druckpatrone 11 angeschlossen wird. In eine mittige, den Adapter 3 durchsetzende Öffnung 3a ragt eine Aufstechnadel 4, welche mit einem Schlagbolzen 5 fest verbunden ist, welcher in einer Öffnung 1 a des Grundkörpers 1 bewegbar angeordnet ist und mit einem Schlagknopf 6 fest verbunden ist, welcher sich im äußeren Bereich der Zentralarmatur befindet. Der Schlagknopf 6 steht in bekannter Weise unter der Wirkung einer Schraubendruckfeder 7, welche am Schlagknopf 6 und am Grundkörper 1 abgestützt ist. Der Schlagknopf 6 und damit auch der Schlagbolzen 5 werden von einem Sicherungselement 8 in der unbetätigten Lage gehalten. Ein am Sicherungselement 8 ausgebildeter Ring 8a erlaubt eine Betätigung des Elementes 8 von Hand aus. Die Zentralarmatur ist ferner mit einem Handgriff 9 versehen, welcher am Grundkörper 1 mittels eines nicht bezeichneten Bolzens gelagert ist. Wie die Schnittdarstellung in Fig. 4 zeigt, ist die Öffnung 3a im Adapter 3 über einen im Grundkörper 1 ausgebildeten Verbindungskanal 1 b mit einem am Grundkörper 1 ausgebildeten Anschluss 1 c verbunden, an welchem ein nicht gezeigtes Blasrohr angeschlossen wird, welches in bekannter Weise im Inneren des Löschmitteltanks 10 untergebracht ist. In Fig. 2 ist weiters ein Steigrohr 12 angedeutet, welches am Grundkörper 1 an einem weiteren Anschluss 1e angeschraubt wird. Ein weiterer Verbindungskanal 1 d im Grundkörper 1 stellt eine Verbindung des Steigrohres 12 zu einem Anschlusselement 14 her, welches am Grundkörper 1 angeschraubt ist und an welchem eine nicht gezeigte Schlauchleitung anbringbar ist.The central valve has a main body 1, which is firmly connected by means of a connection ring 2 with the extinguishing agent tank 10. At the bottom of the central armature projecting into the extinguishing agent tank 10, an adapter 3 is screwed onto the main body 1, to which the pressure cartridge 11 accommodated in the extinguishing agent tank 10 is connected. In a central, the adapter 3 passing through opening 3a protrudes a Aufstechnadel 4, which is fixedly connected to a firing pin 5, which is movably disposed in an opening 1 a of the base body 1 and fixedly connected to a beat button 6, which is in the outer region the central valve is located. The impact button 6 is in a known manner under the action of a helical compression spring 7, which is supported on the impact button 6 and the base body 1. The impact button 6 and thus also the firing pin 5 are held by a securing element 8 in the unactuated position. A trained on the fuse element 8 ring 8a allows actuation of the element 8 by hand. The central valve is further provided with a handle 9 which is mounted on the base body 1 by means of a non-designated bolt. Like the sectional view in Fig. 4 shows, the opening 3a in the adapter 3 is connected via a formed in the base body 1 connecting channel 1 b with a formed on the base body 1 connection 1 c, to which a not shown blower tube is connected, which is housed in a known manner in the interior of the extinguishing agent tank 10. In Fig. 2 Furthermore, a riser pipe 12 is indicated, which is screwed to the base body 1 at a further connection 1e. Another connecting channel 1 d in the base body 1 establishes a connection of the riser pipe 12 to a connection element 14, which is screwed to the base body 1 and to which a hose line, not shown, is attachable.

Wie insbesondere Fig. 3 und Fig. 5 zeigen, ist im Grundkörper 1 von seiner Unterseite her eine Sollberststelle 15 ausgebildet. Diese Sollberststelle 15 ist derart im Grundkörper 1 ausgebildet, dass sie von dem im Inneren des Löschmitteltanks 10 herrschenden Druck unmittelbar beaufschlagt wird und bei einem unzulässig hohen Innendruck aufbricht, sodass der Druck im Inneren des Löschmitteltanks 10 abgebaut wird. Bei der dargestellten Ausführungsform ist an der Sollberststelle 15 eine Vertiefung 15a im Grundkörper 1 ausgebildet, an deren Boden der Grundkörper 1 eine geringe Wandstärke aufweist, welche sich bis zur Mitte der Vertiefung 15a derart verringert, dass in der Mitte der Vertiefung eine Längsrille 15b ausgebildet ist. Entlang des Rillengrundes der Rille 15b ist die Wandstärke bzw. Materialstärke des Grundkörpers 1 am geringsten. An der Außenseite des Grundkörpers 1 ist es nicht erforderlich, die Sollberststelle 15 zu erkennen, sie kann jedoch, beispielsweise mittels einer Markierung oder einer Prägung, an der Außenseite des Grundkörpers 1 angedeutet sein. Wie insbesondere die Schnittdarstellung in Fig. 5 zeigt, ist der Schlagknopf 6 auch als Abdeckung 6b derart ausgebildet, dass er den Grundkörper 1 an jenem Bereich überdeckt, an welchem die Sollberststelle 15 vorgesehen ist.In particular Fig. 3 and Fig. 5 show, a Sollberststelle 15 is formed in the base body 1 from its underside. This Sollberststelle 15 is formed in the base body 1, that it is acted upon directly by the pressure prevailing in the interior of the extinguishing agent tank 10 pressure and breaks at an impermissibly high internal pressure, so that the pressure in the interior of the extinguishing agent tank 10 is reduced. In the illustrated embodiment, a recess 15a in the base body 1 is formed at the Sollberststelle 15, at the bottom of the base body 1 has a small wall thickness, which extends to the center of the Recess 15a is reduced such that in the center of the recess, a longitudinal groove 15b is formed. Along the groove bottom of the groove 15b, the wall thickness or material thickness of the main body 1 is the lowest. On the outside of the main body 1, it is not necessary to recognize the Sollberststelle 15, but it may, for example by means of a mark or an embossing, be indicated on the outside of the base body 1. As in particular the sectional view in Fig. 5 shows, the impact button 6 is also formed as a cover 6b such that it covers the base body 1 at that area at which the Sollberststelle 15 is provided.

Die Funktionsweise eines mit einer derartigen Zentralarmatur versehenen Feuerlöschers ist grundsätzlich an sich bekannt und wie folgt.The operation of a provided with such a central fire extinguisher is basically known per se and as follows.

Durch Ziehen am Ring 8a des Sicherungselementes 8 wird der Feuerlöscher entsichert, wobei eine Plombierung 16, die in Fig. 1 zu sehen ist, zerstört wird. Durch Schlagen auf den Schlagknopf 6 wird der Schlagbolzen 5 nach unten bzw. nach innen bewegt, wodurch die Aufstechnadel 4 die Druckpatrone 11 öffnet, sodass das unter Druck stehende Treibmittel aus der Druckpatrone 11 über den Verbindungskanal 1 d und das Blasrohr in den Löschmitteltank 10 strömt. Das Treibmittel vermischt sich mit dem Löschmittel und wird über das Steigrohr 12 in die Zentralarmatur gedrückt und über den Schlauchleitungsanschluss 14 ausgeblasen.By pulling on the ring 8a of the fuse element 8, the fire extinguisher is unlocked, with a seal 16, the in Fig. 1 can be seen, is destroyed. By striking the knock button 6, the firing pin 5 is moved downwardly or inwardly, whereby the Aufstechnadel 4, the print cartridge 11 opens so that the pressurized propellant flows from the print cartridge 11 via the connecting channel 1 d and the blowpipe into the extinguishing agent tank 10 , The propellant mixes with the extinguishing agent and is forced through the riser 12 in the central valve and blown through the hose line connection 14.

Sollte sich auf unzulässige und ungewollte Weise ein Überdruck im Inneren des Löschmitteltanks 10 aufbauen, bricht die Sollberststelle 15 am Grundkörper 1 auf und der Innendruck wird gefahrlos abgebaut. Schäden an den den Feuerlöscher umgebenden Teilen oder Verletzungen von Personen durch das an der Berststelle 15 austretende Gemisch werden durch den die Berststelle 15 überdeckenden Schlagknopf 6 verhindert.Should an overpressure build up in the interior of the extinguishing agent tank 10 in an inadmissible and unintentional manner, the predetermined bursting point 15 on the main body 1 breaks down and the internal pressure is reduced without danger. Damage to the parts surrounding the fire extinguisher or injury to persons due to the mixture exiting at the rupture point 15 is prevented by the knock button 6 covering the rupture point 15.

Durch die Wahl bzw. Auslegung der Wandstärke bzw. der Materialschwächung an der bzw. den Berststelle(n) - bei der dargestellten Ausführung ist dies die Rille 15b - wird jener Druck bestimmt, der ein Aufbrechen an dieser Stelle bewirken soll.By the choice or interpretation of the wall thickness or the material weakening at the or the rupture point (s) - in the illustrated embodiment, this is the groove 15b - that pressure is determined which is intended to cause a break at this point.

Die Bestandteile der Zentralarmatur, ausgenommen die Anstechnadel 4, die Feder 7, der Bolzen des Handgriffes 9, der Anschlussring 2, gegebenenfalls die Plombierung 16, bestehen aus Kunststoff. Insbesondere sind Anschlussteile, wie der Adapter 3 und der Schlauchanschluss 14, ferner der Schlagknopf 6, das Sicherungselement 8 und der Handgriff 9, Kunststoffteile aus Polyamid oder Polypropylen. Der Grundkörper 1 ist aus einem speziellen Kunststoff, einem glasfaserverstärkten, teilaromatischen Polyamid, beispielsweise aus Ultramid T KR 4355 410 (BASF), hergestellt. Dieses Material zeichnet sich durch eine gute Chemikalienbeständigkeit, eine hohe Zähigkeit und Festigkeit, sowie eine äußerst geringe Wasseraufnahme aus.The components of the central valve, except the piercing needle 4, the spring 7, the bolt of the handle 9, the connecting ring 2, if necessary Seal 16, made of plastic. In particular, connecting parts, such as the adapter 3 and the hose connection 14, also the impact button 6, the securing element 8 and the handle 9, plastic parts made of polyamide or polypropylene. The main body 1 is made of a special plastic, a glass fiber reinforced, partially aromatic polyamide, for example Ultramid T. KR 4355 410 (BASF). This material is characterized by a good chemical resistance, high toughness and strength, and an extremely low water absorption.
