Description

Es sind bereits Gehäuseschieber bekannt, bei denen das keilförmige Abschlußorgan aus zwei Abschlußplatten besteht, die sich gegeneinander bewegen können. Diese Bewegung soll vor allem bei Schiebern mit flachem Gehäuse, bei welchen sich dieses unter der Wirkung des Leitungsdruckes und des keilförmigen Abschlußorgans elastisch besonders stark verformt, eine allseitig gleichmäßige Anpressung der Abschlußplatten an die Dichtflächen des Gehäuses gewährleisten. Hierzu werden die Abschlußplatten zweckmäßig durch eine geeignete Vorrichtung zentral so verbunden, daß ihr Abstand bei entsprechender gegenseitiger Verstellbarkeit unveränderlich ist.Housing slides are already known in which the wedge-shaped closing element consists of consists of two end plates that can move against each other. This movement is intended primarily for sliders with a flat housing, where this is under the effect of the line pressure and the wedge-shaped closing element is elastically particularly strongly deformed, a uniform one on all sides Ensure that the end plates are pressed against the sealing surfaces of the housing. For this the end plates are expediently centralized by a suitable device connected that their distance is invariable with appropriate mutual adjustability is.

Man hat zwar zur Verbindung der Keilplatten schon ein in der Rohrachse angeordnetes Kreuzgelenk vorgeschlagen. Zur Übertragung der Öffnungs- und Schließbewegung von der Schieberspindel auf die Keilplatten wurde aber ein besonderer, die Keilplatten umfassender Ring benötigt, an welchem die Schieberspindel angreift. Diese Ausführung kommt praktisch nur für kleine Schieber in Frage, da dieser Ring größer sein muß als die Schieberlichtweite. Außerdem mußte, um die Einführung des letzten Bolzens beim Zusammenbau des Abschlußorgans zu ermögliehen, dieser länger sein als die halbe Schieberlichtweite. Dadurch werden für größere Rohrlichtweiten das Gewicht des Abschlußorgans, die Baumasse des Gehäuses und die Herstellungskosten unzulässig erhöht.It is true that one already has one arranged in the pipe axis for connecting the wedge plates Universal joint proposed. For transmitting the opening and closing movement from the slide spindle to the wedge plates, however, a special one, the wedge plates Comprehensive ring is required on which the valve spindle engages. This execution is practically only suitable for small sliders, since this ring must be larger than the slider clearance. Also had to avoid the introduction of the last bolt during assembly to allow the closing organ to be longer than half the width of the slide. As a result, the weight of the closing element, the structural dimensions of the housing and the Manufacturing costs increased unacceptably.

Erfindungsgemäß wird die Einrichtung dadurch vereinfacht, daß die Schieberspindel selbst den einen Gelenkzapfen des Kreuzgelenkes bildet. Dadurch kann die Einrichtung auch für größere Schieber mit Erfolg verwendet werden; es wird neben dem Fortfall der angeführten Teile der Vorteil des günstigen Kraftangriffes der Spindel im Keilmittelpunkt erreicht und trotz gegenseitiger Beweglichkeit ein Klappern der Platten durch schädliches Spiel beim Öffnen und Schließen *5 sicher vermieden.According to the invention, the device is simplified in that the slide spindle itself forms the one pivot pin of the universal joint. This allows the facility can also be used with success for larger slide valves; it will be next to the elimination of the parts listed, the advantage of the favorable force application of the spindle in the center of the wedge achieved and despite mutual mobility, rattling of the panels due to harmful play when opening and closing * 5 safely avoided.

Schließlich wird die Baulänge des Abschlußorgans so weit verkürzt, daß die Einrichtung auch für Flachschieber Verwendung finden kann, für welche sie, wie auch oben gesagt, besondere Bedeutung hat. Das in Abschlußstellung dargestellte keilförmige Abschlußorgan besteht aus den beiden Abschlußplatten ι und 1'. An der Abschlußplatte 1 sitzen die beiden Augen 2 und 2', welche mit einer gemeinsamen Bohrung in Richtung der Spindelachse versehen sind. In dieser Bohrung steckt die Spindel 3, die durch die Mutter 4 und einen entsprechenden Ansatz gegen Längsverschiebung gesichert ist.Finally, the length of the closure member is shortened so much that the device can also be used for flat slide valves, for which, as also said above, they are of particular importance. That in the final position The wedge-shaped closure member shown consists of the two closure plates ι and 1 '. At the end plate 1 sit the two eyes 2 and 2 ', which with a common hole in the direction of the Spindle axis are provided. In this hole is the spindle 3, which is through the nut 4 and a corresponding approach is secured against longitudinal displacement.

Um die Spindel schwingt zwischen den Augen 2 und 2' der Stein 5, welcher außen die Zapfen 6 und 6' hat. Um diese Zapfen greifen die geteilten Lager 7 und 7', deren Unterteil unmittelbar mit der Abschlußplatte 1' verbunden sind.The stone 5, which is on the outside, swings around the spindle between the eyes 2 and 2 ' which has pins 6 and 6 '. To this pin engage the split bearings 7 and 7 ', their Lower part are connected directly to the end plate 1 '.

Die beschriebene Vorrichtung bildet dadurch ein Kreuzgelenk, dessen Achsen sich im gleichen Punkt schneiden wie die Spindel- und Rohrachse, so daß eine völlig zentrale, bewegliche Verbindung der Abschlußscheiben geschaffen ist.The device described thereby forms a universal joint, the axes of which are aligned cut at the same point as the spindle and tube axis, so that a completely central, movable connection of the lens panels is created.

Da die Mutter 4 durch die Versteifungsrippen 8 gleichzeitig gegen Drehung gesichert ist, kann die Verbindung der beiden Keilplatten durch Linksdrehen der Spindel 3 leicht gelöst werden.Since the nut 4 is secured against rotation at the same time by the stiffening ribs 8 the connection of the two wedge plates can easily be achieved by turning the spindle 3 to the left be solved.
