Description

Vorrichtungen, z. B. solche, welche auf dem Diffusiousprinzip iberuhen, zum Anzeigen schädlicher Gase in geschlossenen Räumen sind in den verschiedensten Ausführungen bekannt. Devices, e.g. B. those based on the diffusive principle, for displaying harmful gases in closed rooms are in the most varied Executions known.

Vorliegende Erfindung erstreckt sich auf einen Diffusionsanzeiger. Das Neue besteht darin, daß in der Wandung eines Gehäuses eine poröse Aufsaugeschicht angeordnet sowie innerhalb des Gehäuses eine Schwimmereinrichtung mit Kugelverschluß eingebaut ist und daß an einen Rolhrstutzen Ides Gehäuses eine Glasröhre angeschlossen ist. im Zusammenhang hiermit wirkt innerhalb des Gehäuses ferner eine kolbenartige Scheibe mit anschließender Kontrollvorrichtung. The present invention extends to a diffusion indicator. What is new is that there is a porous absorbent layer in the wall of a housing arranged as well as a float device with ball lock within the housing is built in and that a glass tube is connected to a Rolhrstutzen Ides housing is. in connection with this, a piston-like one also acts within the housing Disc with subsequent control device.

Die Zeichnung veranschaulicht eine schematische Darstellung der Erfindung. Sie zeigt einen Vertikalschmnitt durch das Gasanzeigegerät. Auf einer Platte 1, die beliebig aufgehängt oder -gestellt werden kann, ist ein Behälter 2 befestigt. Als Abschluß des Behälters ist oben eine gasdurchlässige Schicht 3 angebracht, durch die sich der Diffusionsdruck auf die Wasser- oder Öloberfläche 4 im Behälter 5 und 6 auswirkt. Auf der Unterseite des Behälters 5 ist ein Rohrstutzen 7 angeschlossen, an welchem eine Glasröhre 8 angeschlossen ist, durch welche die Flüssigkeit hochsteigt. Im Behälter 5 befindet sich ein Schwimmer 9, der sich mit dem Flüssigkeitsspiegel hebt oder senkt. Der Behälter 2 ist an den Behälter I angeschraubt, angegossen oder angeschweißt. An den Schwimmern 9 befindet sich ein Winkelhebel 10, der bei Absinken des Schwimmers 9 über die Verstärkung 11 der Membran I2 den Bolzen I3 bewegt. Dieser lagert in einer Verstärkungsscheibe 14 und drückt die Kontakte 15 und 16 zusammen. Die Einfüllöffnung I7 ist durch einen Gummipfropfen I8 abgedichtet. Unter Idem Schwimmer 9 ist durch eine Kette 19 eine Kugel.' 20 befestigt, die in der Lage ist, die öffnung des Rohrstutzens 7 abzuschließen. The drawing illustrates a schematic representation of the invention. It shows a vertical section through the gas indicator. On a plate 1, which can be hung or placed as desired, a container 2 is attached. As a conclusion of the container, a gas-permeable layer 3 is attached above, through the diffusion pressure on the water or oil surface 4 in the container 5 and 6 affects. A pipe socket 7 is connected to the underside of the container 5, to which a glass tube 8 is connected, through which the liquid rises. In the container 5 there is a float 9, which is with the liquid level raises or lowers. The container 2 is screwed to the container I, cast or welded on. On the floats 9 there is an angle lever 10, which when it drops of the float 9 moves the bolt I3 via the reinforcement 11 of the membrane I2. This is supported in a reinforcing disc 14 and presses the contacts 15 and 16 together. The filling opening I7 is sealed by a rubber stopper I8. Under Idem swimmer 9 is a ball through a chain 19. ' 20 attached, which is able to open the opening of the pipe socket 7 complete.
