Description
Sicherheitsvorrichtung zum Anzeigen von Gasansammlung in Räumen Die Erfindung betrifft eine Sicherheitsvorrichtung, welche beim Eintreten von Gas, insbesondere in Wohnräume .durch undichte Gasleitungen, offene Gashähne u. dgl., in Tätigkeit tritt.Safety device for indicating gas accumulation in rooms The The invention relates to a safety device which, when gas enters, in particular in living rooms through leaky gas pipes, open gas taps, etc., in action occurs.
Es sind derartige Vorrichtungen bereits bekannt, bei denen durch das sich ansammelnde Gas Platinschwamm erwärmt wird und diese Wärme auf ein Thermometer übertragen wird, worauf durch dieses ein elektrischer Strom geschlossen wird, der eine Alarm- oder Sicherheitseinrichtung zum Ansprechen bringt. Gemäß der Erfindung ist durch die Wand des Thermometergefäßes ein metallischer Wärmeübertrager vom Platinschwamm zum Quecksilber hindurchgeführt; es ist also der Wärmewiderstand der Gefäßwand ausgeschaltet.There are such devices already known in which by the The accumulating gas platinum sponge is heated and this heat is applied to a thermometer is transmitted, whereupon an electric current is closed by this, the causes an alarm or safety device to respond. According to the invention is a metallic heat exchanger from the platinum sponge through the wall of the thermometer vessel passed through to mercury; so the thermal resistance of the vessel wall is switched off.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel der neuen Sicherheitsvorrichtung, und zwar zeigt Abb. i diese teils in Vorderansicht, teils im Längsschnitt durch den Glaskörper mit dem Gasfangtrichter, während Abb. a die Vorrichtung teils in Seitenansicht, teils im Querschnitt :erkennen läßt.The drawing illustrates an embodiment of the new safety device, namely Fig. i shows this partly in a front view, partly in a longitudinal section through the glass body with the gas collecting funnel, while Fig. a shows the device partly in Side view, partly in cross section: reveals.
Der thermometerartige Glaskörper a ist mit seiner hinteren Hälfte in eine passende Ausnehmung b eines Brettchens c eingesetzt. Außerdem ist der Glaskörper mit einer dicken Isolationsschicht d umgeben, welche den Einfluß der Zimmertemperatur auf den Glaskörper ausschaltet. Zweckmäßig ist dann ferner die vordere, über dem Brett c hervorstehende Hälfte des Glaskörpers noch mit einer Metallkapsele abgedeckt, die unten als Gasfangtrichter f ausgebildet und oben mit seitlichen Lappen g versehen ist, mit denen die Kapsele bzw. der ganze Glaskörper auf dem Brettchen c durch hindurchgezogene Schrauben festgehalten wird. Der von unten her in den Glaskörper eingeschmolzene Draht /t ist im Grund des Trichters t in Schraubenwindungen gebogen, um darin den Platinschwamm! einklemmen zu können. Ferner ist der untere Draht h durch eine Leitung i an das Alarmelement, beispielsweise an die Glocke k, angeschlossen. Von der Glocke k, die auf einem zu dem Brettchen c gehörigen Deckel i sitzt, führt eine Leitung m zu dem einen Pol it der Stromquelle, die im vorliegenden Beispiel eine kleine, leicht auswechselbare Batterie o ist. Diese sitzt ebenso wie der Glaskörper a in einer entsprechenden Vertiefung p des Brett-. The thermometer-like glass body a is inserted with its rear half into a suitable recess b of a board c. In addition, the glass body is surrounded by a thick insulation layer d, which eliminates the influence of room temperature on the glass body. Appropriately, the front half of the glass body protruding above the board c is also covered with a metal capsule, which is designed as a gas trap f at the bottom and is provided with lateral flaps g at the top, with which the capsule e or the entire glass body on the board c is held in place by threaded bolts. The wire / t melted into the glass body from below is bent in screw turns in the base of the funnel t, around the platinum sponge! to be able to pinch. Furthermore, the lower wire h is connected to the alarm element, for example to the bell k, by a line i. From the bell k, which sits on a cover i belonging to the board c, a line m leads to one pole it of the power source, which in the present example is a small, easily replaceable battery o. This sits just like the glass body a in a corresponding recess p of the board .
chens c. Der andere Pol q der Batterie ist durch eine Leitung r an den von oben her in den Glaskörper eingeschmolzenen Draht l angeschmolzen.chens c. The other pole q of the battery is connected by a line r fused the wire l melted into the glass body from above.
