Description
Die selbsttätige Verriegelung für das Küken von. Hahnen durch den mit dem Küken verbundenen, -als Fallhebel eingerichteten Handgriff ist bereits vorgeschlagen wordem S Bei der bekannten Anordnung erfolgte die Verriegelung aber nur in der Offen-- und in der Schlußstellung des Kükens, während sie in Zwischenstellungen desselben nicht wirksam war. Eine solche selbsttätige Verriege-The automatic locking for the chick of. Cocks by the one with the chick connected handle set up as a drop lever has already been proposed S With the known arrangement, however, locking was only carried out in the open and in the final position of the chick, while it is not effective in intermediate positions was. Such an automatic locking
>o lung ist mithin wertlos bei allen den Hähnen, die nicht nur zum öffnen und Schließen, sondern auch zum Regeln des Durchflußquerschnittes bestimmt sind. Um ein Beispiel zu erwähnen, ist die bekannte selbsttätige Verriegelung für das Küken bei Schweiß- und Schneidbrennern von Acetylenschweißapparaten wertlos, weil deren Hähne zwischen der Offen- und Schlußstellung in den verschiedensten Zwischenstellungen Verwendung finden.> o lung is worthless with all the taps, not only for opening and closing, but also for regulating the flow cross-section are determined. To mention an example, is the well-known self-locking mechanism worthless for the chick in welding and cutting torches of acetylene welding machines, because their taps are between the Open and closed positions are used in a wide variety of intermediate positions.
so Gerade bei Schweiß- und Schneidbrennern ist die selbsttätige Verriegelung des Hahnkükens in allen ihm zugewiesenen Stellungen von großer Wichtigkeit, weil die durch Druck und Stoß ungewollt veranlaßte Drehung des Kükens schädliche Folgen nach sich zieht.so especially with welding and cutting torches the automatic locking of the stopcock in all positions assigned to it by of great importance because the turning of the chick unintentionally caused by pressure and impact has harmful consequences.
Gemäß der Erfindung ist die selbsttätige Verriegelung für das Küken von Hähnen so eingerichtet, daß sie in allen Stellungen des Kükens zuf Wirkung kommt. Zu diesem Zweck ist an dem Fällhebelhandgriff ein zum Eingriff zwischen Küken und Hahngehäuse bestimmter Klemmkeil pendelnd aufgehängt, der in der Klemmstellung mit einem an ihm sitzenden Zahn in Rasten des Hahngehäuses eingreift und so die Blockierung des Kükens in jeder beliebigen Stellung selbsttätig sichert. Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel veranschaulicht. According to the invention, the automatic locking for the chick of cocks is like this arranged that it is effective in all positions of the chick. To this The purpose of the felling lever handle is to enable engagement between the chick and the cock housing certain clamping wedge suspended pendulum, the one in the clamping position with one on him seated tooth engages in notches of the valve body and thus the blocking of the plug automatically secures in any position. The subject matter of the invention is illustrated in an exemplary embodiment in the drawing.
Abb. ι zeigt zum Teil in Außenansicht, zum Teil im Schnitt einen durch die selbsttätige Verriegelung blockierten Gashahn.Fig. Ι shows partly in an external view, partly in section through the automatic Lock blocked gas tap.
Abb. 2 zeigt in einer der Abb. 1 entsprechenden Darstellung den für die Drehung des Kükens entriegelten Gashahn.Fig. 2 shows in a representation corresponding to Fig. 1 for the rotation of the Chick unlocked the gas tap.
Das in dem Hahngehäuse α drehbare Küken b ist an seinem oberen Ende mit einem Fallhebelhandgriff c versehen, dessen Drehpunkt in dem Gelenk d liegt. An dem FaII-hebelhandgriff c ist in dem Gelenk e ein zum Eingriff zwischen Küken und Hahngehäuse bestimmter Klemmkeil f pendelnd aufgehängt. Für das Eindringen des Klemmkeiles / besitzt das Küken b am oberen Ende eine nach dem Gehäuse hin offene Aussparung g, in der der Klemmkeil keiltreibend zur Wirkung" kommt.The chick b rotatable in the tap housing α is provided at its upper end with a lever handle c , the pivot point of which lies in the joint d. A clamping wedge f intended for engagement between the plug and the tap housing is suspended in a pendulum fashion on the case lever handle c in the joint e. For the penetration of the clamping wedge /, the chick b has at the upper end a recess g which is open towards the housing and in which the clamping wedge comes into effect in a wedge-driving manner.
Damit das verriegelte Küken b gegen Drehung gesichert wird, ist an dem Klemmkeil f ein Zahn h angeordnet, der in Rasten i des Hahngehäuses α eingreift. Die Rasten i sind über den ganzen Drehbereich des Kükens b verteilt, so daß der Hahn nicht -nur in der Offen- und in der Schlußstellung, sondern auch in allen Zwischenstellungen selbsttätig verriegelt wird.So that the locked plug b is secured against rotation, a tooth h is arranged on the clamping wedge f , which engages in notches i of the tap housing α. The notches i are distributed over the entire range of rotation of the plug b , so that the cock is automatically locked not only in the open and in the closed position, but also in all intermediate positions.
