Description

Flüseigkeitsfeuerlöscher, dessen Auslaßrohr eine im Druckraum liegende Öffnung besitzt. Gegenstand der Erfindung ist ein Flüssigkeitsfeuerlöscher, dessen Auslaßrohr eine im Druckraute liegende Öffnung besitzt, durch welche eine Verbindung der in dem Löscher eingeschlossenen Luft mit der Außenluft hergestellt wird. Da bei bekannten Löschern dieser Art die Öffnung im Auslaßrohr des Löschers bei dessen Arbeiten störend wirkt, indem Druckgas aus dem Druckrauun des Löschers in das Auslaßrohr überströmt und dadurch einerseüts'für den Arbeitszweck verlorengeht, anderseits aber auch den Löschstrahl zerreißt, so ist bereits vorgeschlagen worden, in den Löscher ein Rückschlagikugelventi7. einzubauen, welches beim Spritzen die erw ,ähnte Öffnung verschließt. Im Laufe der Zeit können sieh derartige Ventile festsetzen, so daß der Innendruck des Löschers nicht ausreicht, um sie in die Schlußlage zu bewegen, oder sie schließen nicht mehr dicht.Liquid fire extinguisher, the outlet pipe of which is located in the pressure chamber Owns opening. The invention is a liquid fire extinguisher whose The outlet pipe has an opening in the pressure diamond through which a connection the air trapped in the extinguisher is produced with the outside air. There in known extinguishers of this type, the opening in the outlet pipe of the extinguisher at the same Working has a disruptive effect by pushing pressurized gas from the pressure roughness of the extinguisher into the outlet pipe overflows and as a result one is lost for the purpose of the work, on the other hand, it also tears up the extinguishing beam, it has already been suggested a non-return ball valve in the extinguisher 7. to be installed, which when spraying the mentioned opening closes. Over time, you may see such valves so that the internal pressure of the extinguisher is not sufficient to bring it into the final position to move, or they will no longer close tightly.

ach der Erfindung erfolgt der Verschluß der Druckausgleichsöffnung am Auslaßrohr des Löschers bei dessen. Ingebrauchnahme durch einen z. B. aus unglasiertem Ton bestehenden porösen Körper, der beispielsweise die Gestalt eines Vollzylinders, eines Röhrchens oder einer Platte bresitzt. Dieser Körper ist infolge seiner Porosität in trockenem Zustande luftdurchlässig, so daß der Druck der im Druckraum des Löschers befindlichen Luft sich gegen den Druck der Außenluft ausgleichen kann. Erfährt der Körper jedoch eine Benetzung durch Flüssigkeit, so wird er sofort luftundurchlässig, weil durch die Flüssigkeitsbenetzung die feinen Poren des Körpers geschlossen werden. Infolgedessen kann der Druck im Luftraum des Löschers nicht mehr durch die Druckausgleichsöffnung entweichen.After the invention, the pressure equalization opening is closed on the discharge pipe of the extinguisher at its. Use by a z. B. from unglazed Clay existing porous body, for example the shape of a full cylinder, a tube or plate. This body is due to its porosity Air-permeable when dry, so that the pressure in the pressure chamber of the extinguisher the air present can balance itself against the pressure of the outside air. Does the However, if the body is wetted by liquid, it immediately becomes impermeable to air, because the wetting of the liquid closes the fine pores of the body. As a result, the pressure in the air space of the extinguisher can no longer pass through the pressure compensation opening escape.

Die Zeichnung veranschaulicht eine Ausführungsform des Erfindungsgegenstandes.The drawing illustrates an embodiment of the subject matter of the invention.

In der Zeichnung ist a ein Feuerlöscher, in dessen oberem Teile sich über dem Flüssigkeitsspiegel in bekannter Weise der Luftraum a' befindet. Der Löscher ist -mit einem Behälter c für Säure oder Druckgas versehen, der mittels eines Schlagstiftes geöffnet werden kann. In das Steigrohr b des Löschers ragt ein Röhrchen, das bei f seine Mündung besitzt, und vor diesem Röhrchen ist in dicht schließender Verbindung mit demselben ein poröser Körper g angeordnet.In the drawing, a is a fire extinguisher, in the upper part of which there is The air space a 'is located above the liquid level in a known manner. The extinguisher is-provided with a container c for acid or compressed gas, which by means of a striker can be opened. A tube protrudes into the riser pipe b of the extinguisher f has its mouth, and in front of this tube is in a tight connection with the same a porous body g arranged.
