Die Erfindung betrifft einen Sprinkler mit integrierter Düse zum Versprühen von Schaummittel-Wasser-Gemischen.The invention relates to a sprinkler with an integrated nozzle for spraying foam agent-water mixtures.
Obige Sprinkler sind bekannt und in der Literatur beschrieben. 10The above sprinklers are known and described in the literature. 10
Dieselben werden für die Brandbekämpfung in großflächigen Gebäuden, wie beispielsweise Kaufhäusern, Hotels oder Lagerhallen verwendet .They are used for fire fighting in large buildings, such as department stores, hotels or warehouses.
Um größere Flächen - beispielsweise eine Lagerhalle - mit Löschmittel abzudecken, sind eine große Anzahl von Sprinklern erforderlich .In order to cover larger areas - for example a warehouse - with extinguishing agents, a large number of sprinklers are required.
Eine Entwicklung in der Brandbekämpfung geht dahin, ein System, bestehend aus vielen Sprinklern und notwendigen Verbindungsleitungen an einem von einem Löschfahrzeug gut anzufahrenden Übergabepunkt für das Schaummittel-Wasser-Gemisch zusammenzufassen. Dieses System ist stets leergespült und entleert. Bei einer erforderlichen Brandbekämpfung wird der Behälter des Löschfahrzeuges, gefüllt mit dem Schaummittel-Wasser-Gemisch an den Übergabepunkt angeschlossen, das fest installierte Absperrorgan geöffnet und Schaummittel-Wasser-Gemisch in die Verbindungsleitungen gedrückt . Dadurch tritt gleichzeitig aus allen Sprinklern das Schaummittel-Wasser-Gemisch aus. Hiermit ist eine optimale Brandbekämpfung gewährleistet.One development in firefighting is to combine a system consisting of many sprinklers and the necessary connecting lines at a transfer point for the foam-water mixture that is easy for a fire engine to reach. This system is always flushed and emptied. When firefighting is required, the fire engine's container filled with the foam-water mixture is connected to the transfer point, the permanently installed shut-off device is opened and the foam-water mixture is pressed into the connecting lines. This means that the foam-water mixture comes out of all sprinklers at the same time. This ensures optimal firefighting.
Als Folge dieser Entwicklung stellte sich die Aufgabe, bei möglichst großem Streukreis der einzelnen Sprinkler und minimalem Löschmittelverbrauch eine optimale Löschwirkung zu erzielen. 35As a result of this development, the task arose of achieving optimum extinguishing effect with the largest possible spread of the individual sprinklers and minimal consumption of extinguishing agent. 35
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Düse mit in Strömungsrichtung konvergierendem Querschnitt ausgebildet ist.This object is achieved according to the invention in that the nozzle is designed with a cross-section that converges in the direction of flow.
Bei dem erfindungsgemäßen Sprinkler wird die Bohrung in der Düse von 11 mm 0 konisch auf 6 mm 0 reduziert.In the sprinkler according to the invention, the bore in the nozzle is reduced conically from 11 mm 0 to 6 mm 0.
Mittels des erfindungsgemäßen Sprinklers kann nahezu die doppelte Fläche bei geringerem Schaummittel-Wasser-Gemisch-Verbrauch bei gleicher Löschwirkung abgedeckt werden.Using the sprinkler according to the invention, almost twice the area can be covered with less foam agent-water mixture consumption and with the same extinguishing effect.

Gleichzeitig ergeben sich Einsparungen bezüglich baulicher Maßnahmen zur Löschmittelruckhaltung.At the same time, savings are made with regard to structural measures for fire extinguishing agent retention.
