Description

Schlüssel zur Erleichterung des öffnens @üh- ie kleinen Handrädern versehenen Ventilen Die Erfindung bezieht sich auf einen Schlüssel zur Erleichterung des öffnens von mit kleinen Handrädern versehenen Ventilen, insbesondere von solchen an Stahlflaschen für hocbkomprimierte Gase, z. B. Sauerstoff usiv. Die Erfahrung zeigt, daß diese Ventile .nur schwer zu öffnen sind und daß oft durch Benutzung ungeeigneter Hilfsgeräte die Ventile selbst beschädigt werden.Key to facilitate opening @ üh- ie small handwheels provided valves The invention relates to a key for relief the opening of valves provided with small handwheels, especially such on steel cylinders for high-compression gases, e.g. B. Oxygen usiv. The experience shows that these valves are difficult to open and that often through use unsuitable auxiliary devices damage the valves themselves.

Gemäß der Erfindung sind nun bei- einem Schlüssel mit .zwei durch Schraubenspindel gegeneinander verstellbaren Klemmbacken an der Unterseite der Klemmbacken Auflageflächen angeordnet, an deren Außenrändern Greifklauenpaare mit Greifkanten angebracht sind. Mittels der Auflageflächen kann der Schlüssel auf die Handräder aufgelegt und mittels der Schraubenspindel können die Greifklauen fest an die Handräder gepreßt und diese mit Hilfe der als Drehhebel dienenden Schraubenspindel gedreht werden. Ein kräftiges Zudrehen und gutes Schließen wie auch ein Öffnen läßt sich ohne große Anstrengung und ohne Beschädigen der Ventile - erzielen, da das Handrad 3 genau zentrisch beansprucht wird.According to the invention, a key with .zwei is now through Screw spindle mutually adjustable clamping jaws on the underside of the clamping jaws Arranged bearing surfaces, on the outer edges of which pairs of gripping claws with gripping edges are appropriate. The key can be placed on the handwheels by means of the contact surfaces The gripping claws can be firmly attached to the handwheels by means of the screw spindle pressed and this rotated with the help of the screw spindle serving as a rotary lever will. A strong turning and good closing as well as opening can be done without much effort and without damaging the valves - achieve as the handwheel 3 is stressed exactly in the center.

. In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt, und zwar zeigen Abb. i eine Seitenansicht, Abb. z einen Grundriß des Ventils, wobei einzelne Teile im Schnitt dargestellt sind, Abb. 3 und- q. den Schlüssel je an einer Stahlflasche angebracht.. In the drawing is an embodiment of the subject matter of Invention shown, namely show Fig. I a side view, Fig. Z a plan view of the valve, with individual parts shown in section, Fig. 3 and - q. the Key attached to a steel bottle.

Der Schlüssel hat zwei Klemmbacken z, z, die auf einer gemeinsamen Schraubenspindel 3 angeordnet sind. Die Backe i ist mit Gewinde versehen, während die Backe a drehbar, aber in axialer Richtung nicht verschiebbar ist. Die Backen r, a sind mittels Stifte und Bohrungen 5 aneinander geradegeführt. Jede Backe weist auf der Unterseite eine Auflagefläche und, von dieser ausgehend, zwei nach unten ragende Greifklauen 6 auf. Diese Klauen greifen über den Rand des Handrades $ des Ventils, wobei die Greifkanten der Klauen mittels der Schraubenspindel 3 fest an den Außenrand des Handrades angepreßt werden. Die Spinde13 ist mit einem Griffstück 7 versehen, das an seinen beiden Stirnenden Vierkantlöcher 8, 9 hat, mit denen Ventile von Gasflaschen geöffnet und geschlossen werden können, die kein Handrad, dafür aber ein Vierkant an der Ventilspindel aufweisen.The key has two clamping jaws z, z, which are on a common Screw spindle 3 are arranged. The jaw i is threaded while the jaw a is rotatable, but not displaceable in the axial direction. The cheeks r, a are brought together by means of pins and holes 5. Every cheek points one support surface on the underside and, starting from this, two downwards protruding gripping claws 6. These claws grip over the edge of the handwheel $ des Valve, with the gripping edges of the claws firmly attached by means of the screw spindle 3 pressed against the outer edge of the handwheel. The locker13 is with a handle 7 provided, which has square holes 8, 9 at its two front ends, with which valves Can be opened and closed by gas bottles that do not have a handwheel, for that but have a square on the valve stem.
