Description

Die Erfindung betrifft eine VerbesserungThe invention relates to an improvement

der Absperrvorrichtungen, die mit einem in der Verschlußlage in seinem Durchmesser erweiterten und dadurch an die Gehäusewand gedrückten Kolbenschieber versehen sind.the shut-off devices with one in the closed position in its diameter extended and thereby pressed against the housing wall piston slide are provided.

Nach der Erfindung besteht der Kolbenschieber aus einem Hohlkörper aus Gummi oder einem anderen elastischen, Stoff, der nach dem Einführen in die Verschlußlage to durch die Antriebsvorrichtung ausgedehnt wird. Es wird etwa ein Hohlzylinder aus Gummi samt einem geteilten Ring mit konischer Bohrung auf einer Platte angeordnet, die mit Spiel an einem Schlitten angeschlossen ist, so daß beim Senken des Schlittens der Gummizylinder zunächst bis vor die Leitung gesenkt und daran nach Auflagerung im Gehäuse durch den sich weiter senkenden kegelförmigen Teil des Schlittens ausgedehnt wird.According to the invention, the piston valve consists of a hollow body made of rubber or another elastic, material, which after insertion into the closure layer to is expanded by the drive device. It will be made from roughly a hollow cylinder Rubber and a split ring with a conical bore arranged on a plate, which is connected to a slide with play, so that when the slide is lowered the rubber cylinder is initially lowered to in front of the line and then after it has been supported expanded in the housing by the conical part of the slide that descends further will.

In der Zeichnung ist eine Ausführungsform'der Vorrichtung dargestellt. Es zeigen: Fig. ι einen Längsschnitt des geschlossenen Ventils,An embodiment of the device is shown in the drawing. Show it: Fig. Ι a longitudinal section of the closed valve,

Fig. 2 einen Längsschnitt des geöffneten Ventils,2 shows a longitudinal section of the opened valve,

Fig. 3 einen Querschnitt.
In dem Ventilgehäuse α ist der mit einem Ansatz e in einer Nut / des Gehäuses geführte Schlittenkörper d angeordnet, der durch die mit Handrad c versehene Spindel b gehoben und gesenkt werden kann. Auf einer Platte I, die mit axialem Spiel durch die Mitnehmer k des Schlittens mit diesem verbunden ist, sind der Gummihohlzylinder h und die aus Stahl hergestellten Halbzylinder g angeordnet. Die beiden Halbzylinder haben eine kegelförmige Innenfläche und umgeben den kegelförmigen Ansatz i des Schlittens. Beim Hochziehen des Schlittens bleibt zunächst der Hohlzylinder k in seiner Lage, während sich in ihm der Kegel i aufwärts bewegt. Erst dann wird durch die Köpfe k die Platte I mitgenommen, welche den Hohlzylinder k trägt. Beim Schließen des Ventils hängt die Platte Z an dem Mitnehmer k, bis sie auf dem Ring m des Gehäuses aufgelagert wird. Dann erst kann sich beim weiteren Senken des Schlittens der kegelförmige Teil/ gegenüber dem Hohlzylinder k und den beiden Schalen g senkein. Es wird dadurch der Gummizy]inder ausgedehnt und abdichtensfest an die Gehäusiewand gepreßt.3 shows a cross section.
The slide body d , which is guided with an extension e in a groove / of the housing and can be raised and lowered by the spindle b provided with a handwheel c , is arranged in the valve housing α. The hollow rubber cylinder h and the half cylinder g made of steel are arranged on a plate I, which is connected to the slide with axial play by the driver k of the slide. The two half-cylinders have a conical inner surface and surround the conical extension i of the slide. When the slide is pulled up, the hollow cylinder k initially remains in its position, while the cone i moves upwards in it. Only then is the plate I carried along by the heads k , which carries the hollow cylinder k. When the valve closes, the plate Z hangs on the driver k until it is supported on the ring m of the housing. Only then can the conical part / opposite the hollow cylinder k and the two shells g lower itself when the slide is lowered further. As a result, the rubber is expanded and pressed tightly against the housing wall.
