KAISERLICHESIMPERIAL PATENTAMTPATENT OFFICE Der Schieber ist den allgemein bekannten ähnlich. Zwischen Dichtungsflächen a a, Fig. 2, bewegt sich der in der Richtung c d keilförmige Schieber b, welcher aus einem oberen vollen Theil für die Absperrung der Flüssigkeit und einem unteren durchbrochenen Theil besteht, welcher den Durchflufs gestattet. Die Auf- und Abbewegung geschieht auf bekannte Weise durch eine in ihrer Lage festgehaltene Schraube e, Fig. ι, und die Mutter f. Die seitliche Führung wird aufser durch die Dichtungsflächen a a durch zwei eingelegte T - Schienen g g, Fig. 2, bewirkt, welche in der Achse des Schiebers c d eine Bewegung zulassen, und durch welche der Keil fester gegen die Dichtungsflächen geprefst werden kann, um eine vollständige Abdichtung zu erzielen. Das Festhalten der Schienen in der eingestellten Lage geschieht durch die Schrauben h. Die Dichtungsflächen a a sind auch nach unten fortgesetzt, so dafs es, da der volle Theil des Schiebers in seiner ganzen Fläche abdichtet, der Flüssigkeit nicht möglich ist, in das Gehäuse des Schiebers einzutreten. In dem Gehäuse ist bei i eine Oeffnung geschaffen, welche die in dem durchbrochenen Theile des Schiebers b eingeschlossene Flüssigkeit ins Freie entweichen läfst.The slide is similar to the commonly known ones. The slide b , which is wedge-shaped in the direction cd , moves between the sealing surfaces aa, FIG. The up and down movement takes place in known manner by a pinned in position bolt e, Fig ι, and the mother f the lateral guide is, besides by the sealing surfaces aa by two inserted T -... Gg rails, Figure 2, causes which allow movement in the axis of the slide cd , and through which the wedge can be pressed more firmly against the sealing surfaces in order to achieve a complete seal. The rails are held in the set position by the screws h. The sealing surfaces aa are also continued downwards, so that, since the full part of the slide seals in its entire surface, the liquid is not able to enter the housing of the slide. An opening is made in the housing at i , which allows the liquid enclosed in the perforated part of the slide b to escape into the open. Die ganze Anordnung hat den Zweck, das Absetzen eines Niederschlages auf den Dichtungsflächen α α zu verhindern.The whole arrangement has the purpose of preventing a deposit from settling on the sealing surfaces α α. Pa τent-Ansρruch:Pa τent claim: Bei Absperrschiebern eine für den Flüssigkeitsdurchgang durchbrochene Verlängerung der im Querschnitt normal zur Bewegungsrichtung des Schiebers keilförmigen und in dieser Richtung mittelst Führungsleisten und Druckschrauben gegen ihre beiden gegenüberliegenden Sitzflächen geprefsten Schieberplatte b, welche Verlängerung ebenfalls zwischen den Dichtungsflächen liegt, auch beim Oeffnen des Schiebers die Flüssigkeit vom Innern des Schiebergehäuses abschliefst und so das Absetzen eines Niederschlages auf den Dichtungsflächen verhindert. In the case of gate valves, an extension of the valve plate b, which is perforated for the passage of liquid, is wedge-shaped in cross section normal to the direction of movement of the valve and is pressed in this direction by means of guide strips and pressure screws against its two opposing seat surfaces, which extension is also between the sealing surfaces, the liquid from the opening of the valve Locks inside the valve body and thus prevents precipitation from settling on the sealing surfaces. Hierzu 1 Blatt .Zeichnungen.1 sheet of drawings.
