Gasdichtes Kugelventil und Verfahren zu dessen Herstellung .Gas-tight ball valve and process for its manufacture.
Die Herstellung gasdichter Ventile, insbesondere Kugelventile, bietet erhebliche Schwierigkeiten, weil es schwer fällt, für die Ventilkugel und den Ventilsitz Materialien zu finden, die eine genügende Dichtwirkung ergeben und die zugleich an sich genügend gasdicht sind, um jede Diffusion auszuschliessen. Die vorliegende Erfindung beruht nun auf der überraschenden Feststellung, dass es bei geeigneter Formgebung des Ventilsitzes möglich ist, mit sehr harten Materialien, beispielsweise Sinterkeramik, Saphir, RubinThe manufacture of gas-tight valves, especially ball valves, presents considerable difficulties because it is difficult falls to find materials for the valve ball and the valve seat, which give a sufficient sealing effect and which are at the same time sufficiently gas-tight to rule out any diffusion. The present invention is now based on the surprising finding that it is possible with a suitable shape of the valve seat, with very hard Materials such as sintered ceramics, sapphire, ruby

Es ist dabei besonders auch das Problem zu lösen, eine Beschädigung des aus dem harten, spröden Material bestehenden Ventilsitzes durch die Ventilkugel zu vermeiden.and the like, a high level of tightness of the valves reach. The problem to be solved is that of damaging the hard, brittle material to avoid existing valve seat by the valve ball.

stimmter Form vorgesehen, nämlich zwei kugelige Flächen oder Fasen 3 und 4, deren Radian R3 bzw. R4 betragen. Die' Fasen 3 und 4 stossen mit stumpfem Winkel aneinander und bilden dort eine stumpfe Kante 5. Die Kugel 2 liegt auf " der dichtenden Fase 4 auf, während zwischen ihr und der Fase 3 ein gewisses Spiel besteht. Eine der mittleren Neigung der Fase 3 angepasste Kegelfläche weist vorzugsweise einen Oeffnungswinkel von 90 bis 120 auf. Mit andern Worten beträgt die mittlere Neigung der Fiise 3 zur Achse des Ventils vorzugsweise 45 bis 60 . Bei einem Durchmesser D der Ventilbohrung von 1,2 nun beträgt beim Ausführungsbeispiel der Radius R3 1,25 mm, der Radius R4 0,75 mm, derjenige der Kugel 2 ebenfalls 0,75 mm, die radiale Breite in der Projektion gemessen der beiden Fasen 0,08 nun, die radiale Breite der Fase 4 in der Projektion gemessen 0,03 mm, die axiale Distanz A 0,055 mm und die axiale Distanz B 0,027 mm.A certain shape is provided, namely two spherical surfaces or chamfers 3 and 4, the radians of which are R3 and R4, respectively. The' Chamfers 3 and 4 meet at an obtuse angle and form an obtuse edge 5 there. The ball 2 rests on it "of the sealing bevel 4, while there is a certain amount of play between it and the bevel 3. One of the medium inclinations The conical surface adapted to the bevel 3 preferably has an opening angle of 90 to 120. In other words is the mean inclination of the Fiise 3 to the axis of the Valve preferably 45 to 60. With a diameter D of the valve bore of 1.2 in the exemplary embodiment the radius R3 1.25 mm, the radius R4 0.75 mm, that of the sphere 2 also 0.75 mm, the radial width in the projection measured the two bevels 0.08 now, the radial width of the bevel 4 in the projection measured 0.03 mm, the axial Distance A 0.055 mm and the axial distance B 0.027 mm.
Form und Abmessungen der Fasen des Ventilsitzes sind unter den folgenden massgebenden Gesichtspunkten gewählt:The shape and dimensions of the bevels of the valve seat are selected based on the following criteria:
Die Ventilkugol soll auf dom Sitz nicht haften bleiben.

Swerving to avoid us v / ground hard, brittle material of the valve seat and / or the valve ball at the abrupt landing "of the valve ball against the seat. This is achieved by the auxiliary bevel 3 and the breaking of the edge 5. Even if the ball hits a little eccentrically, it will be in the middle
