Description
Das Abdichten von gegeneinander beweglichen Teilen aus keramischen Werkstoffen bietet b°-sondereSchwieri,gkeiten. Beispielsweise zeigten sich bei den in der chemischen Industrie verwendeten Porzellanventilen nach mehr oder weniger langer Zeit, .daß diese undicht werden, obwohl die Ventile bei der Prüfung unter Druck dicht waren.The sealing of mutually moving parts made of ceramic Materials offers special difficulties. For example, the Porcelain valves used in the chemical industry to a greater or lesser extent long time, .that these are leaking, although the valves are under the test Pressure were tight.
Gemäß der Erfindung wird der genannt:-, Nachteil dadurch beseitigt, d@aß die Dichtungsflächen des einen Teils aus einem in der Härte von dem des anderen Teils verschiedenen Werkstoff bestehen. Die weichere Schicht des einen Teils paßt sich der gegenüberstehenden härteren Schicht besser an und ergibt hierdurch eine guteDichtung. DieDichtungsfläche des einen Teils kann z. B. mit einem metallischen, insbesondere korrosionsfesten Überzug versehen werden, der beispielsweise aus Edelmetall oder einem V z A-Stahl beisteht.According to the invention, the is called: -, disadvantage is eliminated by d @ ate the sealing surfaces of one part of one in hardness of that of the other Partly consist of different material. The softer layer of one part fits adapts itself better to the harder layer opposite and thereby results in a good seal. The sealing surface of the one part may e.g. B. with a metallic, In particular, a corrosion-resistant coating can be provided, for example made of noble metal or a V z A steel.
In der Figur ist ein Aus:führungsheispiel an Hand eines Ventils aus 'keramischem Werkstoff dargestellt. Das Ventil i besteht aus keramischem Werkstöff, z. B. Porzellan, und weist einen Ventilsitz a auf. Die Ventilspindel 3 kann auch aus Porzellan bestehen. Ihre Dichtungsfläche 4 wird nach Schleifen und Einjustieren mit einer weicheren Schicht, z. B. mit Platin oder V 2 A-#Belag, überzogen.The figure shows an embodiment using a valve 'Ceramic material shown. The valve i consists of ceramic material, z. B. porcelain, and has a valve seat a. The valve spindle 3 can also made of porcelain. Your sealing surface 4 is after grinding and adjusting with a softer layer, e.g. B. with platinum or V 2 A- # coating, coated.
