Description

Die Erfindung 'betrifft eine Abdichtung der Spindel von Absperrorganen, wie sie in dem Hauptpatent beschrieben ist. Bei dieser Abdichtung nach dem .Hauptpatent wird der an der kegelstumpfförmigen Dichtungsfläche des Spindelbundes anliegende Dichtungsring durch eine Feder' angedrückt und ist mit dem Gehäuse durch eine Ringmembran aus Gummi od. dgl. verbunden.The invention 'relates to a sealing of the spindle of shut-off devices, as in the Main patent is described. With this seal according to the main patent, the frustoconical sealing surface of the spindle collar abutting sealing ring by a Spring 'pressed and is with the housing by an annular diaphragm made of rubber od. Like. tied together.

ίο Die Erfindung ist eine weitere Ausgestaltung des Gegenstandes des Hauptpatents und bezweckt, die besondere Druckfeder zum Anpressen des Dichtungsringes an den Spindelring einzusparen. Die Erfindung besteht darin, daß die den Dichtungsring allein tragende, federnde Ringmembran eine konzentrische Sicke oder Einbuchtung besitzt. Durch eine solche Ausbildung der federnden Membran wird diese radial elastisch gestaltet, so daß sie in der Lage ist, auch beim Verkanten der Spindel ein sicheres Anliegen des Dichtungsringes an der kegelstumpfförmigen Dichtung des Spindelbundes zu gewährleisten, ohne daß eine relative Verschiebung zwischen Spindelbund und Dichtungsring auftritt. Bei Dichtungen für schnell 'umlaufende Wellen ist es an sich bekannt, einen Dichtungsring mit Hilfe einer federnden Ringmembran gegen einen radialen Flansch anzupressen, jedoch ist hier eine radiale Elastizität der Membran nicht vorhanden.ίο The invention is a further embodiment the subject of the main patent and aims to press the special compression spring of the sealing ring to the spindle ring. The invention consists in that the Sealing ring alone supporting, resilient annular membrane a concentric bead or indentation owns. Such a design of the resilient membrane makes it radially elastic, so that it is able to ensure a secure fit of the sealing ring even when the spindle is tilted to ensure on the frustoconical seal of the spindle collar without a relative displacement between the spindle collar and sealing ring occurs. With seals for fast 'Circumferential shafts, it is known per se, a sealing ring with the aid of a resilient annular membrane to be pressed against a radial flange, but here there is a radial elasticity of the membrane unavailable.

In der Zeichnung ist die Erfindung beispielsweise dargestellt.In the drawing, the invention is shown as an example.

Abb. ι zeigt eine Abdichtung gemäß der Erfindung für Druckleitungen;Fig. Ι shows a seal according to the invention for pressure pipes;

Abb. 2 zeigt eine Anwendung der Dichtung für wechselnde Drücke.Fig. 2 shows an application of the seal for alternating pressures.

Gemäß Abb. 1 ist auf der Ventilspindel 1 ein Bund 2 angeordnet, der eine kegelstumpfförmige Dichtungsfläche besitzt. An dieser liegt der Dichtungsring 3 an. Der Dichtungsring 3 wird durch die federnde ringförmige Membran 4 ständig gegen den Bund 2 der Spindel gedrückt. Die Membran 4 ist einerseits mit dem Dichtungsring 3 und andererseits mit dem Gehäuse 5 fest und dicht verbunden und besitzt eine konzentrische Sicke oder Einbuchtung, die eine axiale und radiale Bewegung zuläßt. Bei Verwendung einer solchen Abdichtung in Vakuumleitungen ist die Abdichtung in umgekehrter Anordnung anzuwenden, d. h., Dichtungsfläche, Dichtungsring und Membran liegen oberhalb des Spindelbundes.According to Fig. 1 is on the valve spindle 1 Collar 2 arranged, which has a frustoconical sealing surface. The sealing ring is located on this 3 on. The sealing ring 3 is by the resilient annular membrane 4 constantly against the Collar 2 of the spindle pressed. The membrane 4 is on the one hand with the sealing ring 3 and on the other hand firmly and tightly connected to the housing 5 and has a concentric bead or indentation which allows axial and radial movement. When using such a seal in vacuum lines the sealing is to be used in reverse order, i.e. i.e., sealing surface, sealing ring and membrane are above the spindle collar.

Die in Abb. 2 dargestellte Ausführungsform ist für wechselnde Beanspruchungen gedacht. Hier besitzt die Spindel 1 einen Bund 2, der auf beiden Seiten mit einer kegelstumpfförmigen Dichtungsfläche versehen ist. Gegen jede Dichtungsfläche liegt ein Dichtungsring 3 an, der mittels der federnden Ringmembran 4 mit dem Gehäuse 5- verbunden ist. Gegebenenfalls kann der Raum 6 oberhalb der oberen Membran mit einer geeigneten Flüssigkeit gefüllt sein.The embodiment shown in Fig. 2 is intended for changing loads. Here owns the spindle 1 has a collar 2 which is provided on both sides with a frustoconical sealing surface. Lies against each sealing surface a sealing ring 3, which is connected to the housing 5 by means of the resilient annular membrane 4. If necessary, the space 6 above the upper membrane can be filled with a suitable liquid be filled.
