Description
Die Erfindung betrifft einen Sicherheits-Gasschlauchhähn mit zwei ineinander angeordneten und durch eine Feder auf ihre Dichtungsflächen gepreßte Hahnküken.The invention relates to a safety gas hose cock with two cock plugs arranged one inside the other and pressed onto their sealing surfaces by a spring.
Es sind bereits Gashahnschließvorrichtungen bekannt, bei welchen ein über die Hahntülle gezogener Schlauch mittels eines Hebels ein federbelastetes Schließorgan in Offenstellung hält, das durch die Feder vor den Gasdurchgang geschoben wird, sobald der Schlauch von der Tülle gleitet.There are already known gas tap closing devices in which one over the tap nozzle pulled hose by means of a lever a spring-loaded closing element in the open position that is pushed by the spring in front of the gas passage as soon as the hose slides off the spout.
Ferner gibt es Gashähne mit zwei ineinander angeordneten Küken, die durch eine Feder gemeinsam auf ihre Dichtungsfläche gepreßt werden.There are also gas taps with two nested chicks, which are connected by a Spring are pressed together on their sealing surface.
Diese Einrichtungen sind nach der Erfindung in der Weise vereinigt, daß an dem inneren Küken ein den Hahn bei aufgezogenem Schlauch in Offenstellung haltender Hebel befestigt ist.These devices are combined according to the invention in such a way that on the inner Chick is attached to a lever holding the cock in the open position when the hose is open.
Durch diese Kombination wird erreicht, daß durch die das Schließen des inneren Kükens bewirkende Feder zugleich ein Anpressen der beiden Küken an ihre Dichtungsflächen erfolgt und der Gasdurchgang stets frei von Verunreinigungen gehalten wird, da es nur erforderlich ist, das äußere Küken einmal von Hand zu drehen, um die Verunreinigungen von den Gleitflächen sowohl am Gehäuse als auch am inneren Küken abzustoßen.This combination ensures that the closing of the inner Chick causing spring at the same time a pressing of the two chicks on their sealing surfaces takes place and the gas passage always is kept free from contamination as it is only required to use the outer chick once to turn by hand to remove the debris from the sliding surfaces on both the housing as well as to repel on the inner chick.
In der Zeichnung ist ein solcher Sicherheits-Gasschlauchhahn beispielsweise dargestellt.In the drawing, such a safety gas hose tap is shown, for example.
Fig. ι zeigt den Hahn im Längsschnitt in Offenstellung.Fig. Ι shows the cock in longitudinal section in the open position.
Fig. 2 stellt einen Querschnitt des offenen Hahnes dar.Fig. 2 shows a cross section of the open tap.
Fig. 3 zeigt den Hahn im Grundriß in Schließstellung.Fig. 3 shows the cock in plan in the closed position.
Das Hahnküken b ist in seinem Gehäuse eingeschliffen und mit dem Griff c fest verbunden. In seinem Innern lagert eingeschliffen das kleine Küken d mit dem Hals e, an dem der Hebel f befestigt ist. Beide Küken sind senkrecht zur Achse durchbohrt. Die Gewindekappe g schließt das Gehäuse staubdicht ab, und die Schraube h sichert dieselbe gegen Drehung. Die Kopfschraube h dient gleichzeitig als Anschlag für den Hebel f in Offenstellung und begrenzt mit Hilfe der Aussparung i auch die Drehung des Hahnkükens b in bekannter Weise. Die Feder k ist einmal an dem Küken d festgeklemmt und andererseits durch eine Scheibe / mit der Kappe g am Gehäuse festgeschraubt. Der Hebel f wird mit seinem blattförmigen Ende m durch den Schlauch am Tüllenhals η festgehalten, wie aus Fig. 1 und 2 ersichtlich. Da der Tüllenhals mit seiner Abplattung zwischen dem Hahngehäuse und der eigentlichen Schlauchtülle t liegt, wird ferner erreicht, daß bereits beim Beginn des Abgleitens, also dann, wenn der Schlauch von dem Hebelende m abgleitet, aber noch mit der Schlauchtülle t verbunden ist, der Hebel / freigegeben wird und durch die Feder k das innere Küken d bereits in die Schließstellung gezogen werden kann.The cock plug b is ground in its housing and firmly connected to the handle c. The small chick d with the neck e, to which the lever f is attached, rests in its interior. Both chicks are pierced perpendicular to the axis. The threaded cap g closes the housing in a dust-tight manner, and the screw h secures the same against rotation. The head screw h also serves as a stop for the lever f in the open position and, with the aid of the recess i, also limits the rotation of the cock plug b in a known manner. The spring k is clamped on the one hand to the plug d and on the other hand is screwed to the housing by a washer / with the cap g. The lever f is held with its leaf-shaped end m by the hose on the nozzle neck η , as can be seen from FIGS. Since the spout neck is t with its flattened portion between the tap body and the actual hose, is further achieved, that is to say when the hose from the lever end of m derived, but t already connected at the start of slipping or with the hose, the lever / is released and the inner plug d can already be pulled into the closed position by the spring k.
