Description
Gegenstand der Erfindung ist eine Verbesserung an Löschvorrichtungen, bei denen die Absperrhähne von Speiseleitungen unter der Wirkung von Gewichten stehen, die durch Abbrennen von Brennschnüren ausgelöst werden und dadurch die Löschleitung unter Einschaltung einer Lärmvorrichtung in Tätigkeit setzen.The invention is an improvement to extinguishing devices in which the Stopcocks of feed lines are under the action of weights that pass through Burning of burning cords are triggered and thereby the extinguishing line is switched on put a noise device into action.
Die Erfindung bezieht sich darauf, Sicherheit dafür zu schaffen, daß die in Rohre verlegten Brennschnüre unter allen Umständen das Feuer weiterleiten, d. h. daß die Verbrennung von dem freien Ende der Schnüre bis zu der Stelle, an der die Auslösung der den Wasserzufluß regelnden Hähne geschieht, unter allen Umständen sicher erfolgt. Die Einbettung der Brennschnüre in Rohre ist erforderlich, um sie gegen Beschädigung zu sichern und J die Wirksamkeit der Anlage zu gewährleisten. Es hat sich aber gezeigt, daß solche in Rohre eingebetteten Brennschnüre das Feuer nicht zuverlässig weiterleiten, sondern daß oftmals aus unbekannten Gründen die Brennschnüre im Rohre sehr rasch erlöschen. .The invention relates to providing security that the laid in pipes Burning cords transmit fire under all circumstances, d. H. that the burning of the free end of the cords up to the point at which the triggering of the water inflow Regulatory faucets happens to be done safely under all circumstances. The embedding of the Burning cords in pipes are required to secure them against damage and J die Ensure the effectiveness of the plant. But it has been shown that such in pipes embedded burning cords do not reliably pass the fire on, but that often from for unknown reasons, the burning cords in the pipe go out very quickly. .
Dieser Nachteil kann nach den Feststellungen des Erfinders in sicherer Weise dadurch ausgeschlossen werden, daß man die für die Aufnahme der Brennschnüre bestimmten Rohre mit einem die Wärme schlecht leitenden Baustoff, wie beispielsweise Pappe, Papier, auskleidet. Brennschnüre, die in Rohren mit einer derartigen Auskleidung verlegt sind, haben nach dem Ergebnis angestellter Versuche die Entzündung unter allen Umständen sicher weit er geleitet, ohne daß irgendwelche Störung aufgetreten ist. Brennschnüre, die daneben in gewönlichen Rohren verlegt waren, haben dagegen nur eine ganz kurze Strecke im Rohre gebrannt. ■ .According to the inventor's findings, this disadvantage can thereby be safely excluded that the tubes intended to hold the burning cords are fitted with a building material that does not conduct heat well, such as cardboard, paper, for example. Burning cords laid in pipes with such a lining, According to the results of the experiments, the inflammation is certain under all circumstances far he passed without any disturbance having occurred. Burning cords next to it were laid in ordinary pipes, on the other hand, have only a very short distance in the pipe burned. ■.
