Description
Die Erfindung bezieht sich auf ein Absperrorgan mit senkrecht zur Durchflußrichtung angeordneter Ventilspindel, bei welchem ein kegelförmig ausgebildeter Absperrkörper und ein schräg zur Durchflußrichtung liegender Ventilsitz verwendet wird.The invention relates to a shut-off device with perpendicular to the direction of flow arranged valve spindle, in which a cone-shaped shut-off body and a valve seat at an angle to the direction of flow is used.
Das Neue besteht darin, daß der Absperrkörper als Kegelstumpf ausgebildet ist und das untere Ende annähernd unter demselbenThe new thing is that the shut-off body is designed as a truncated cone and the lower end approximately below the same

Hierdurch wird der Vorteil erzielt, daß beim kleinsten Hub des Absperrkörpers jede Geschwindigkeitsänderung des Flüssigkeitsstromes, welche durch den Absperrkörper her- This has the advantage that with the smallest stroke of the shut-off body each Change in speed of the liquid flow, which is caused by the shut-off body

Auf der Zeichnung ist die Erfindung in einer beispielsweisen Ausführungsform dargestellt, und zwar in einem senkrechtenIn the drawing, the invention is shown in an exemplary embodiment, namely in a vertical
as Schnitt,the cut,
Wie aus der Zeichnung ersichtlich, ist a das Gehäuse des Absperrorgans, in welchem in einem aufgesetzten Kopfstück oder Oberteil b der Absperrkörper c senkrecht geführt wird. In dem Gehäuse α des Absperrorgans liegt der Ventilsitz d schräg zur Durchflußrichtung des Mediums.As is apparent from the drawing, a housing of the obturator, in which in a mounted head or upper part b of the shut-c is performed vertically. In the housing α of the shut-off element, the valve seat d is inclined to the direction of flow of the medium.
Der Absperrkörper c ist hierbei in bekannter Weise derart angeordnet,. daß er in senkrechter Richtung auf und ab bewegt werden kann, ohne daß eine Verdrehung des Absperrkörpers erfolgt.The shut-off body c is here arranged in a known manner. that it can be moved up and down in the vertical direction without twisting the shut-off body.
Nach der vorliegenden Erfindung ist der senkrecht auf und ab bewegbare Absperrkörper c als Kegelstumpf ausgebildet, und das untere Ende ist annähernd unter demselben Winkel, unter dem der Ventilsitz zur Durchflußachse geneigt ist, derart abgeschnitten, daß bei geschlossenem Absperrkörper die schräge Fläche des Kegelstumpfes annähernd in der Ebene der Unterkarte der Sitzfläche liegt. According to the present invention, the shut-off body c , which can be moved vertically up and down, is designed as a truncated cone, and the lower end is cut off at approximately the same angle at which the valve seat is inclined to the flow axis, so that when the shut-off body is closed, the inclined surface of the truncated cone is approximately in the level of the sub-map of the seat.
Wird der Absperrkörper durch ein Handrad e auf und ab bewegt, so wird beim kleinsten Hub nach oben die Durchflußöffnung derart freigegeben, daß die Geschwindigkeitsänderung des Flüssigkeitsstromes möglichst vermieden wird.If the shut-off body is moved up and down by a handwheel e , the flow opening is opened with the smallest upward stroke in such a way that the change in speed of the liquid flow is avoided as far as possible.
