Description

Absperrhahn mit kugelförmigem Küken Gegenstand der Erfindung ist ein Absperrhahn mit kugelförmigem Küken, das mit Spiel im Gehäuse läuft und durch eine am Zuflußstutzen sitzende, lideitingsartig wirkende Dichtung abgedichtet wird.Stopcock with a spherical plug The invention relates to a Stopcock with a ball-shaped plug that runs with play in the housing and through a at the inlet connection seated, lideiting-like acting seal is sealed.

Bei den bekannten Absperrhähnen dieser Art muß mit Rücksicht uf :die Halterung der liderungsartigen Dicrtung der Durchmesser des Gehäuses sehr :groß ausgeführt werden, wenn das Küken von oben in das Gehäuse eingesetzt werden soll.In the case of the known shut-off valves of this type, with regard to: the Holder of the lilac-like thickness the diameter of the case is very: large carried out when the plug is to be inserted into the housing from above.

Um diesen Mangel zu beheben, wird gemäß der Erfindung das Gehäuse durch einen quer zur Drehachse liegenden Deckel abgeschlossen, .der auf seiner Innenseite einen Ansatz aufweist, welcher bei aufgeschraubtem Deckel die obere Hälfte des kreisringförmigenWiderlagers für die liderungsartigeDichtung bildet.In order to remedy this deficiency, according to the invention, the housing Completed by a cover lying transversely to the axis of rotation, the one on its inside has an extension which, when the cover is screwed on, the upper half of the annular abutment for the eyelid-like seal.

Infolge dieser Anordnung wird neben dem geringeren Durchmesser des Gehäuses eine Form desselben erreicht, die fabrikationstechnisch leicht :durch Gießen und Pressen ohne Unterscbneidungen im Gehäuseinnern herstellbar ist, so daß die spanabhebende Bearbeitung auf .das :geringste Maß beschränkt werden kann, indem nur die Anschlußstutzen einer mechanischen Bearbeitung bedürfen.As a result of this arrangement, in addition to the smaller diameter of the Housing achieved a shape of the same that is technically easy to manufacture: by casting and pressing can be produced without undercuts in the housing interior, so that the Machining can be limited to the lowest level by only the connecting pieces require mechanical processing.

Damit ist .die Üöglichkeit gegeben, den Hahn auch aus säurebeständigem Material herzustellen, und zwar aus Porzellan, Glas o. d-1., ohne daß eine Bearbeitung des Gehäuseinneren nötig ist.This gives the possibility to also make the tap from acid-resistant Manufacture material, namely from porcelain, glass o. D-1., Without any processing the inside of the housing is necessary.

Hähne gemäß .der Erfindung eignen sich besonders für Feuerlöschgeräte, und zwar insonderheit für Strahlrohre.Taps according to the invention are particularly suitable for fire extinguishers, in particular for nozzles.

Auf der Zeichnung sind Ausführungsformen eines solchen Hahnes dargestellt, und zwar zeigt: Fig. z einen senkrechten Längsschnitt eines geöffneten Hahnes, der besonders zum Abschluß von Strahlrohren geeignet ist, Fig. 2 einen waagerechten Schnitt zu Fig. i mit geschlossenem .Küken.In the drawing, embodiments of such a cock are shown, namely shows: Fig. z a vertical longitudinal section of an open tap, the is particularly suitable for terminating radiant tubes, Fig. 2 a horizontal section to Fig. i with closed .Küken.

In dem Hahngehäuse i sitzt das Küken 2, das durch einen Handgriff 3 um 90° gedreht werden kann. Das Küken 2 ist in seinem mittleren Teil .I kugelförmig ausgebildet und besitzt einen unteren Zapfen 5, der in einem Lager 6 des Gehäuses i drehbar ist. Das Gehäuse i paßt sich in seiner unteren Hälfte 7 der Kugelform des Kükens an, ohne dieses zu berühren. Die obere Hälfte 8 des Gehäuses i ist zylindrisch ausgeführt und im Durchmesser nichtviel größer als der Kükendurchmesser, so daß man das kugelförmige Küken 2 von oben in das Gehäuse i einstecken kann. Dieser zylindrische Teil des Gehäuses wird durch einen Deckel 9 abgeschlossen, welcher einett in die zylindrische Hälfte 8 bis zur Mittelachse hineinragenden Teil io besitzt, der sich im wesentlichen der Kugelform des Kükens anpaßt. In dem Deckel 9 ist der Zapfen i i des Kükens 2 drehbar gelagert. Das Küken stützt sich mit einem Rand 12 gegen einen Ring 13, über welchen eine Manschette 14 gelegt ist, die das Küken gegen den Durchtritt von Flüssigkeit nach außen abdichtet.In the tap housing i sits the plug 2, which is operated by a handle 3 can be rotated by 90 °. The chick 2 is spherical in its central part .I formed and has a lower pin 5, which is in a bearing 6 of the housing i is rotatable. The housing i fits in its lower half 7 of the spherical shape of the chick without touching it. The upper half 8 of the housing i is cylindrical executed and not much larger in diameter than the plug diameter, so that you can insert the spherical plug 2 into the housing i from above. This cylindrical one Part of the housing is closed by a cover 9, which is embedded in the cylindrical half 8 to the central axis protruding part io has, which substantially adapts to the spherical shape of the chick. In the cover 9 is the pin i i of the plug 2 rotatably mounted. The chick is supported with an edge 12 against a ring 13, over which a sleeve 14 is placed, which the chick against the Seals the passage of liquid to the outside.

Zur Abschlußdichtung des Kükens :2 gegenüber dem Hahngehäuse an der Durchflußöffnung 20 ist ein Leder oder Gummistulp 15 im Gehäuse i vorgesehen, der mit einer Seite sich gegen einen Rand 16 des Gehäuses i bzw. des Teils io legt und durch ein Rohrstück 17 in seiner Lage gehalten wird. Beim Anschrauben des Rohr- oder Schlauchanschlusses auf den Gewindezapfen i8 wird .das Rohrstück 17 gegen den Stulp 15 gedrückt. Der freie Rand i9 des Stulps 15 legt sich gegen die Kugelfläche q. des Kükens 2 und wird bei geschlossenem Küken.2 (Fig. 2) durch den Wasser- oder Flüssigleeitsdruch gegen die Kugelfläche 4 gedrückt. Infolge der Kugelfläche -. kann das Küken 2 auch mit seinem Durchgang 2o an dem Rand i9 des Stulps 15 bei der Drehung des Kükens glatt vorübergehen, ohne diesen zu beschädigen.To seal the plug: 2 against the tap housing at the flow opening 20 , a leather or rubber sleeve 15 is provided in the housing i, one side of which rests against an edge 16 of the housing i or part io and through a piece of pipe 17 in its position is held. When the pipe or hose connection is screwed onto the threaded pin i8, the pipe section 17 is pressed against the faceplate 15. The free edge i9 of the faceplate 15 lies against the spherical surface q. of the plug 2 and is pressed against the spherical surface 4 by the water or liquid duct when the plug 2 is closed (Fig. 2). As a result of the spherical surface -. the chick 2 can also pass smoothly with its passage 2o on the edge i9 of the faceplate 15 during the rotation of the chick without damaging it.

Es ist nur erforderlich, daß das Küken in dem kugelförmigen Teil einigermaßen glatt ist, damit sich der Rand i9 liderungsartig an das Küken 2 anlegen kann.It is only necessary that the chick is somewhat in the spherical part is smooth so that the edge 19 can lie against the chick 2 like an eyelid.

Die Begrenzung der Kükenstellung erfolgt zweckmäßig durch nicht dargestellte Anschläge, die am Umfang des Randes 12 innerhalb des Gehäuses i liegen und mit letzterem zusammenarbeiten.The position of the chicks is expediently limited by not shown Stops that lie on the periphery of the edge 12 within the housing i and with the latter work together.

Um das Küken 2 ständig gegen :den Ring 13 und die Manschette 14 zu drücken, ist eine Feder 25 vorgesehen, die in einer Aussparung 26 des unteren Zapfens 5 liegt.To the chick 2 constantly against: the ring 13 and the cuff 14 to press, a spring 25 is provided in a recess 26 of the lower pin 5 lies.
