Description

Die Erfindung betrifft eine Absperrvorrichtung mit senkrecht zur Strömungsrichtung Hegender Spindel und schräg zur Spindel liegender Diclitungsfläche. Die bekannten S Absperrvorrichtungen dieser Art haben den Nachteil, daß die Widerlager für den Ventilkörper unter einem spitzen Winkel zur Dichtungsfläche angeordnet sind. Hierdurch entsteht eine Keilwirkung, die bei höheren Temperaturen infolge der Ausdehnung von Gehäuse und Ventilkörper ein Festklemmen des Ventilkörpers zur Folge hat und daher derartige Absperrschieber trotz ihrer sonstigen Vorzüge für höhere Temperaturen unbrauchbar macht. Dieser Nachteil ist erfindungsgemäß dadurch beseitigt worden, daß die Widerlager seitlich im Gehäuse außerhalb des Durchströmungsquerschnittes derart angeordnet sind, "daß Ventilsitz 'und Anschläge Teile von Grundfläche und Mantel desselben ideellen Zylinders bilden. Infolge dieser Anordnung werden SchuBkräfte" vermieden; es treten nur zu Sitz und Anschlägen senkrechte Druckkräfte auf.The invention relates to a shut-off device perpendicular to the direction of flow Hanging spindle and diagonal surface at an angle to the spindle. The known S shut-off devices of this type have the disadvantage that the abutment for the valve body are arranged at an acute angle to the sealing surface. This creates a wedge effect that occurs at higher temperatures due to the expansion of the housing and valve body results in jamming of the valve body and therefore such Gate valves, despite their other advantages, cannot be used for higher temperatures power. This disadvantage has been eliminated according to the invention in that the Abutment laterally in the housing outside of the flow cross-section arranged in this way are, "that valve seat 'and stops parts of the base and surface of the same ideal cylinder. As a result of this Arrangement are shear forces "avoided; only pressure forces perpendicular to the seat and stops occur.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt. Es zeigen:The invention is shown in the drawing, for example. Show it:

Abb. ι einen senkrechten Mittelschnitt durch das Gehäuse,Fig. Ι a vertical center section through the housing,

Abb. 2 eine Ansicht des Gehäuses vonoben, Abb. 3 denselben Schnitt wie Abb. 1 mit eingezeichnetem Ventilkörper,Fig. 2 is a view of the housing from above, Fig. 3 the same section as Fig. 1 with shown valve body,

Abb. 4 einen Schnitt nach Linie 4-4 der Abb. i.Fig. 4 is a section along line 4-4 of Fig. I.

Die Ventilspindel 5 ist in der gebräuchlichen Weise senkrecht zur Ventillängsachse angeordnet, der Ventilsitz δ dagegen etwa unter einem Winkel von 450 zu ihr. Der Ventilkörper hat einen senkrecht zu seiner Dichtungsfläche b1 angeordneten zylindrischen Teil^, der mit den seitlich im Gehäuse außerhalb des Durchströmungsquerschnittes vorgesehenen Anschlägen c, deren wirksame Flächen ebenfalls senkrecht zur Dichtungsfläche stehen, zusammenwirkt.The valve stem 5 is arranged in the usual manner perpendicular to the valve longitudinal axis, on the other hand, the valve seat δ approximately at an angle of 45 0 to it. The valve body has a cylindrical part which is arranged perpendicular to its sealing surface b 1 and which interacts with the stops c provided laterally in the housing outside the flow cross-section, the effective surfaces of which are also perpendicular to the sealing surface.
