Abstract
Die Erfindung betrifft eine Zumischeinrichtung für Feuerlöschanlagen zum Zumischen eines schaum- oder filmbildenden Zusatzmittels zu einem Löschwasserstrom, mit einer Zusatzmittelleitung, die an eine Löschwasserleitung angeschlossen ist und endseitig zu mindestens einer Abgabestelle (20 - 23) führt, wobei zur Erhöhung der Dosiergenauigkeit bei besonders großem Durchflußmengenbereich vorgeschlagen wird, daß in der Löschwasserleitung und der Zusatzmittelleitung jeweils ein Durchflußmeßgerät (3, 4) angeordnet ist, die mit einer zentralen Steuereinheit (9) gekoppelt sind, die zur Errechnung der erforderlichen Menge an Zusatzmittel unter Berücksichtigung des an einem Wahlschalter (12) digital eingestellten Sollwertes einen Rechner (19) aufweist, der mit einem Antriebsmotor (2') einer Schaummittelpumpe (2) gekoppelt ist. The invention relates to an admixing device for fire extinguishing systems for admixing a foam or film-forming additive to an extinguishing water stream, with an additive line which is connected to an extinguishing water line and leads at the end to at least one dispensing point (20-23), increasing the metering accuracy with a particularly large one Flow range is proposed that in each case a flow meter (3, 4) is arranged in the extinguishing water line and the additive line, which are coupled to a central control unit (9) which is used to calculate the required amount of additive, taking into account that on a selector switch (12) has a computer (19), which is coupled to a drive motor (2 ') of a foam agent pump (2).
