Description
Die Erfindung betrifft einen Hahn, insbesondere für die Getränkeindustrie, dessen konisches Küken mittels zweier in Aussparungen des Kegelmantels eingelegter Ringdichtungen abgedichtet ist und durch ein zwischen dem Küken und einer Überwurfmutter angeordnetes federndes Zwischenteil nachgiebig in seinem Gehäusesitz gehalten wird.The invention relates to a tap, in particular for the beverage industry, the conical plug by means of two ring seals inserted in recesses of the cone jacket and sealed by an between the chick and a union nut arranged resilient intermediate part resilient in his Housing seat is held.
Bei den als bekannt angeführten Hähnen, welche mittels zweier in Aussparungen des Kegelmantels eingelegter Ringdichtungen abgedichtet sind, sind zwischen der Überwurfmutter und dem Hahnküken Federn angeordnet, um so eine nachgiebige Anpressung zu erzielen. Die Anordnung von Federn hat den Nachteil, daß sich in diesen Schmutz ansammeln kann, welcher Infektionen des Getränkes zur Folge hat.In the case of the taps listed as known, which by means of two recesses in the cone shell inserted ring seals are sealed between the union nut and the cock plug Arranged springs in order to achieve a resilient contact pressure. The arrangement of springs has the Disadvantage that dirt can collect in this, which results in infections of the beverage.
Es ist auch bekannt, bei Hähnen zwischen der Überwurfmutter und dem Küken eine elastische Dichtung einzusetzen. Um die Gleitreibung zwischen der als Dichtring vorgesehenen Dichtung und der Überwurfmutter zu verringern, ist der Dichtring mit einer Stahlringkappe abgedeckt, die auf einem aus PoIytetrafluoräthylen bestehenden Gleitring gleitet. Bei dieser Anordnung finden jedoch mehrere Einzelteile Verwendung, an denen sich gleichfalls Schmutz in unerwünschter Weise absetzen kann.It is also known to have an elastic seal between the union nut and the plug in taps to use. About the sliding friction between the seal provided as a sealing ring and the union nut To reduce, the sealing ring is covered with a steel ring cap, which is made of polytetrafluoroethylene existing slip ring slides. In this arrangement, however, find several items Use on which dirt can also settle in an undesirable manner.
Die Mangel der bekannten Ausführungen werden durch die Ausführung nach der Erfindung dadurch vermieden, daß als federndes Zwischenteil ein Gleitring, der in bekannter Weise aus einem gute Gleiteigenschaften aufweisenden Kunststoff, z. B. PoIytetrafluoräthylen, besteht, mit einer elastischen Einlage bzw. einem Weichkern angeordnet ist. Der glatte Gleitring aus Polytetrafiuoräthylen oder ähnlichem Werkstoff bietet keine Möglichkeit zur Ansammlung von Schmutz od. dgl. Durch eine elastische Einlage bzw. einen Weichkern wird eine besonders gute Nachgiebigkeit ohne Aufgabe der Gleiteigenschaften erzielt.The shortcomings of the known designs are thereby made by the design according to the invention avoided that as a resilient intermediate part a sliding ring, which in a known manner from a good sliding properties comprising plastic, e.g. B. Polytetrafluoroethylene, consists, is arranged with an elastic insert or a soft core. The smooth one Sliding ring made of polytetrafluoroethylene or similar material offers no possibility of accumulation from dirt or the like. An elastic insert or a soft core ensures particularly good flexibility achieved without giving up the sliding properties.
In der Zeichnung ist ein Ausführungsbeispiel des Hahnes nach der Erfindung wiedergegeben.In the drawing, an embodiment of the tap according to the invention is shown.
In bekannter Weise ist in das Hahngehäuse 1 das Hahnküken 2 eingesetzt. Das Hahnküken 2 ist am oberen und unteren Ende mit Nuten 3 versehen, in welche Rundschnurringe 4 eingelegt sind. Das Hahnküken 2 ist mit einem Handgriff 5 ausgestattet, um dessen Ansatz am Küken ein Gleitring 6, z. B. aus Polytetrafluoräthylen, gelegt ist. Das Hahnküken 2 wird in seinem Sitz durch eine Überwurfmutter 7 gehalten, welche auf das am Kopf des Hahngehäuses befindliche Gewinde aufgeschraubt wird.The cock plug 2 is inserted into the cock housing 1 in a known manner. The cock plug 2 is on The upper and lower ends are provided with grooves 3 into which O-rings 4 are inserted. The cock chick 2 is equipped with a handle 5 to its approach on the chick a sliding ring 6, z. B. off Polytetrafluoroethylene, is laid. The cock plug 2 is held in its seat by a union nut 7, which is screwed onto the thread on the head of the tap housing.
Bei der Drehung des Hahnkükens 2 im Gehäuse 1 gleitet das Hahnküken 2 mit dem Gleitring 6 auf der Überwurfmutter 7. Der Werkstoff des Gleitringes 6When the cock plug 2 rotates in the housing 1, the cock plug 2 slides with the sliding ring 6 on the Union nut 7. The material of the sliding ring 6

besitzt besonders günstige Gleiteigenschaften und ist gegen Erwärmen unempfindlich.has particularly good sliding properties and is insensitive to heating.
Da das Hahnküken 2 bei heißen Flüssigkeiten stärker aufwärmt als das Hahngehäuse 1, wandert das Hahnküken 2 bei größerer Koinzität aus seinem Sitz gegen die Überwurfmutter 7. Dann wird der Gleitring 6 infolge der elastischen Einlage zusammengedrückt, ohne daß die Gleiteigenschaften leiden. Der Weichkern des Gleitringes 6 dehnt sich beim Abkühlen des Hahnes wieder aus, so daß ein gleichmäßiger Anlagedruck von der Überwurfmutter 7 über den Gleitring 6 auf das Hahnküken 2 ausgeübt wird.Since the cock plug 2 warms up more than the cock housing 1 with hot liquids, the cock plug 2 migrates from its seat against the union nut 7 with greater coincidence. Then the sliding ring 6 is compressed due to the elastic insert without the sliding properties suffer. The soft core of the sliding ring 6 expands again when the cock cools, so that a uniform contact pressure is exerted on the cock plug 2 by the union nut 7 via the sliding ring 6.
