Hochdruckschieberventil.
Die Erfindung bezieht sich auf ein insbesondere zur Absperrung von hochgespannten und hochüberhitztem Dampf geeignetes Hochdru. ckschieberventil, bei welchem nur ein Absperrkorper nach Art eines Ventils entgegen der Durchströmrichtung dadurch in die Schliessstellung gebracht wird, dass dem Absperrkörper unter Vermittlung von an die Stellspindel angeschlossenen, kniehebelartig wirkenden Lenkern eine aus der Kombination vertikaler und horizontaler Bewegung sich ergebende Führung erteilt wird.
Das Wesentliche der Erfindung ist die Kraftübertragung von den Lenkern auf den Absperrkörper unter Vermittlung eines zentral angeordneten, beweglichen Zwischenstücks, das die seitlich wirkenden Kräfte der Lenker vollkommen zentrisch auf den Absperrkörper überträgt.
Ferner werden Ungenauigkeiten, z. B. Formänderungen durch Temperatureinflüsse oder Ab-

In Fig. 1, die ein Ausführungsbeispiel schematisch darstellt, bezeichnet 2 das Schieber- gehäuse, 2 den ventilartigen Absperrkörger, der beispielsweise mit Kanten-oder Kegeldichtung bei 3 gegen die Strömungsrichtung abdichtet und bei 4 im Zutrittsquerschnitt des Schieber- gehäuses zentriert wird. Das Gelenkstück 5 soll diese Zentrierung unabhängig von der Lage des Lenkerstückes 6 gestatten. Dieses trägt z. B. unten eine Rohrführung 7, die bei geöffnetem
Schieber dem Dampfe einen völlig ungehinderten Durchtritt gewährt.
Unterhalb des Rohr- stückes 7 befinden sich Rollen 8, welche die senkrechten Kräfte der Kniehebel aufnehmen.

High pressure slide valve.
The invention relates to a high pressure particularly suitable for shutting off high pressure and superheated steam. Slide-back valve, in which only one shut-off element in the manner of a valve is brought into the closed position counter to the flow direction in that the shut-off element is given a guide resulting from the combination of vertical and horizontal movement through the intermediary of toggle-like links connected to the adjusting spindle.
The essence of the invention is the power transmission from the links to the shut-off body through the intermediary of a centrally arranged, movable intermediate piece which transfers the laterally acting forces of the link completely centrally to the shut-off body.
Furthermore, inaccuracies such. B. Changes in shape due to temperature influences or

transferred
In FIG. 1, which schematically shows an exemplary embodiment, 2 designates the valve housing, 2 the valve-like shut-off body, which seals against the flow direction at 3 with an edge or cone seal and is centered at 4 in the access cross section of the valve housing. The joint piece 5 should allow this centering regardless of the position of the handlebar piece 6. This carries z. B. below a pipe guide 7, which when open
Slide allows the steam a completely unhindered passage.
Underneath the pipe section 7 there are rollers 8 which absorb the vertical forces of the toggle levers.

be transmitted. The drawing shows a rising spindle which is operated by the nut 11 and the handwheel 12. The counter nut 11 a can limit the knee lever effect.
Fig. 2 * is. A horizontal section through the valve housing of a valve construction which is essentially the same as the embodiment according to FIG. 1 on a larger scale and shows the structural design of the parts for the free movement of the shut-off body.
The digits denote. therein the same parts as in Fig. l. Next are 13 guide rollers with a cylindrical or spherical rolling surface, through which the toggle pressures of the tabs 9 are directly on the valve housing in de. n strips 14 for the closing forces and in the
Support strips 15 for the opening forces. 16 is one that fits into the shut-off body
Hemispherical piece. which runs out in a bolt and is connected by the head screw 17 to the handlebar 6 also on train for the transmission of the opening forces. 18 is that
Supplementary hemispherical piece, which together with 16 allows all-round rotation of the valve body. The track bearing piece 19, in which the ball piece 18 sits, also allows
