Description
Luftschaumerzeuger Die Erfindung betrifft einen Luftschaumerzeuger für Feuerlöschzwecke mit einem an beiden Enden offenen Rohr, bei welchem nahe dem einen Ende die zur Schaumbildung dienende Flüssigkeit durch einen Düsenkopf zerstäubt wird, und mit kegeligem Einsatzkörper in der Düsenöffnung.Air foam generator The invention relates to an air foam generator for fire extinguishing purposes with a pipe open at both ends, in which near the one end atomizes the liquid used for foam formation through a nozzle head and with a tapered insert in the nozzle opening.
Ein bekannter Luftschaumerzeuger dieser Art besteht im wesentlichen aus einem an beiden Enden offenen Rohr, bei welchem nahe dem einen Ende die zur Schaumbildung dienende Flüssigkeit durch einen Düsenkopf zerstäubt wird, in dem ein kegeliger Einsatzkörper vorgesehen ist. A known air foam generator of this type essentially consists from a tube open at both ends, in which near one end the to Foaming liquid is atomized through a nozzle head in which a conical insert body is provided.
Die vorliegende Erfindung bezweckt, eine vereinfachte Form eines Schaumerzeugers dieser Art zu schaffen, und besteht darin, daß der sich in der Strömungsrichtung verjüngende kegelige Einsatzkörper in der sich ebenfalls in der Strömungsrichtung verjüngenden kegeligen Düsenöffnung so angeordnet ist, daß die einzelnen aus der Düsenöffnung austretenden Flüssigkeitsteilchen unmittelbar über der Düsenöffnung gegeneinanderprallen. The present invention aims to provide a simplified form of a To create foam generator of this type, and consists in that the in the flow direction tapered conical insert body in which is also in the direction of flow tapered conical nozzle opening is arranged so that the individual from the Liquid particles emerging from the nozzle opening directly above the nozzle opening crash against each other.
Durch diese Ausbildung wird gegenüber den bekannten Schaumerzeugern dieser Art ein kegelmantelförmiger Ringstrahl gebildet, dessen Spitze sich unmittelbar über der Düse befindet und so die gesamte dem Flüssigkeitsstrahl mitgeteilte Energie in der Hauptsache zur Zerstäubung benutzt wird. This training is compared to the known foam generators of this type a cone-shaped ring beam is formed, the tip of which is directly located above the nozzle and so the entire energy communicated to the liquid jet is mainly used for atomization.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. The drawing shows an embodiment of the subject matter of the invention shown.
Die Düse I ist an ihrem Auslaßende kegelig geneigt und in der Mitte mit einem kegeligen Auslaß 2 versehen. In der Mitte der Auslaßöffnung, welche sich nach der Offnung hin verengt, ist ein kegeliger Einsatzkörper 3 angeordnet, welcher in geeigneter Weise befestigt ist und gegebenenfalls versehiebbar sein kann, so daß mittels desselben die Durchlaßöffnung beliebig geregelt oder abgesperrt werden kann. Die durch den kegeligen Hohlraum ringsum austretenden Flüssigkeitsteilchen prallen im Scheitelpunkt gegeneinander, so daß eine feine Zerstäubung der Flüssigkeitsteilchen erzielt wird. The nozzle I is tapered at its outlet end and in the middle provided with a conical outlet 2. In the middle of the outlet opening, which is Narrowed towards the opening, a conical insert body 3 is arranged, which is attached in a suitable manner and can optionally be displaceable, so that by means of the same the passage opening can be regulated or blocked as desired can. The liquid particles emerging all around through the conical cavity collide against each other at the apex, so that a fine atomization of the liquid particles is achieved.
