Description

Verfahren zur Druckerhöhung in Feuerlöschern, die durch Anschluß an eine Druckwasserleitung den zum Abspritzen erforderlichen Druck erhalten. Es ist bekannt, Feuerlöscher durch Anschließen an eine Druckwasserleitung zu füllen, wobei ein Zusammenpressen: der im Feuerlöscher enthaltenen Luft erfolgt. Diese zusammengepreßte Luft dient dann beim Abspritzen des Feuerlöschers als Druckmittel zum Austreiben der Löschflüssigkeit. In dieser Weise gefüllte Feuerlöscher zeigen den Nachteil, daß infolge zu schnellen Druckabfalles die Reichweite des Strahles allmählich abnimmt. Man hat also praktisch damit zu rechnen, daß die Löschwirkung gegen Ende des Abspritzens nachteilig beeinflußt wird.Process for increasing pressure in fire extinguishers by connecting to a pressurized water pipe will receive the pressure required for hosing down. It is known to fill fire extinguishers by connecting it to a pressurized water line, wherein a compression: the air contained in the fire extinguisher takes place. This compressed When the fire extinguisher is hosed down, air then serves as a pressure medium to expel it the extinguishing liquid. Fire extinguishers filled in this way have the disadvantage that as a result of too rapid a pressure drop, the range of the jet gradually decreases. So you have to count on the fact that the extinguishing effect towards the end of the spraying is adversely affected.

Gegenstand der Erfindung ist nun ein diesen Nachteil beseitigendes Verfahren zur Druckerhöhung, welches darin besteht, daß vor dem Füllen in den Löschflüssigkeitsbehälter zur Gaserzeugung an sich bekannte Stoffe eingebracht werden, deren Gaserzeugungsfähigkeit vorübergehend dadurch verzögert wird, daß sie in einer, gegebenenfalls mehrere Kammern enthaltenden Kapsel, oder in mehreren Kapseln aus einem in der Löschflüssigkeit verhältnismäßig leicht löslichen Stoffe, z. B. Gelatine, untergebracht sind. Die Wandstärke der Gelatinekapseln ist so bemessen, daß die Auflösung der Gelatine frühestens nach beendigter Füllung und erfolgtem Verschließen des Löschers stattfindet. Hat sich dann die Kapsel gelöst, so entwickelt ihr Inhalt, je nach seiner Zusammensetzung durch Berührung mit der Löschflüssigkeit eine Gasmenge, die den durch das Füllen an der Druckwasserleitung geschaffenen Luftdruck um so viel verstärkt, als zum vollständigen Austreiben der Löschflüssigkeit in einem Strahle von annähernd gleichbleibender Reichweite erforderlich ist.The subject of the invention is now a solution that eliminates this disadvantage Process for increasing the pressure, which consists in that before filling into the extinguishing liquid container substances known per se are introduced to generate gas, their gas generating capacity is temporarily delayed by the fact that they are in one, possibly several chambers containing capsule, or in several capsules from one in the extinguishing liquid relatively easily soluble substances, e.g. B. gelatin, are housed. the The wall thickness of the gelatin capsules is such that the gelatin does not dissolve at the earliest takes place after filling is complete and the extinguisher has been closed. Has If the capsule is then dissolved, its contents develop according to its composition by contact with the extinguishing liquid, an amount of gas that is sufficient for the filling The air pressure created at the pressurized water pipe is increased by as much as it is completely Driving out the extinguishing liquid in a jet of approximately constant Range is required.
