Die meisten der im Gebrauch befindlichen Absperrschieber leiden an dem Uebelstände, dafs sie sich infolge einseitigen Anpressens des Schieberkeiles nur schwer und zeitraubend öffnen und schliefsen lassen.Most of the gate valves in use suffer from the problem that they are difficult and time-consuming as a result of one-sided pressing of the valve wedge open and close.
Um diese Uebelstände zu beseitigen und das Oeffnen und Schliefsen schnell und leicht bewerkstelligen zu können, ist der in der Zeichnungdargestellte Schieber so construirt, dafs der Schieberkeil in geschlossenem Zustande des Schiebers vollständig entlastet ist.To remedy these inconveniences and to open and close quickly and easily to be able to, the slide shown in the drawing is designed so that the valve wedge is completely relieved when the valve is closed.
Die Entlastung geschieht dadurch, dafs der auf den . Schieberkeil wirkende Druck durch die Kanäle k auf die entgegengesetzte Seite geleitet wird und dort auf eine Ringfläche am Schieberkeil drückt, deren FlächeninhaltThe relief takes place by the fact that the on the. Pressure acting on the valve wedge is passed through the channels k to the opposite side and there presses on an annular surface on the valve wedge, the surface area of which

ist. Hierdurch wirkt auf beiden Seiten des Schiebers, ein gleich grofser Druck und der Schieber ist infolge dessen entlastet.is. As a result, an equal pressure and the pressure act on both sides of the slide As a result, the pressure on the slide is relieved.
Der innere Druck kann auch durch Umführungsrohre oder Kanäle auf die betreffende Ringfläche geleitet werden.The internal pressure can also be applied to the affected area through bypass pipes or ducts Ring surface are guided.
In den weitaus meisten Fällen wird es genügen , den Schieber bezw. Schieberkeil nur einseitig — nicht wie in der Zeichnung zweiseitig — mit Entlastungsvorrichtung auszubilden. In the vast majority of cases, it will be sufficient to move the slide respectively. Valve wedge only one-sided - not two-sided as in the drawing - to be designed with a relief device.
