Description

Absperrschieber mit zwei parallelen in einem Tragring gehaltenen Absperrplatten Die Erfindung bezieht sich auf einen Absperrschieber mit zwei parallelen Absperrplatten, die in einem Tragring gehalten und nur senkrecht zur Spindelachse verfahrbar angeordnet sind. Bei Absperrschiebern mit diesen Ausführungsformen besteht die Schwierigkeit, die Absperrplatten in die Schließstellung und aus ihr unter möglichst kleiner Reibung zwischen Gehäuse und Absperrplatten zu bewegen und dabei doch dann einen sicheren Abschluß zu gewährleisten. Bei den bekannten Ausführungsformen stehen die Absperrplatten durch ein Hebelgetriebe miteinander in kraftschlüssiger Verbindung. Bei dem Bewegen der Verschlußeinrichtung in die Offenstellung liegt der die Absperrplatten tragende Ring am Gehäuse an. Beim Bewegen in die Schließstellung tritt infolge der Hebelanordnungen an der Spindel ein Anliegen auch der Absperrplatten am Gehäuse ein, so daß eine zusätzliche Reibung vorhanden ist. Es ist daher Aufgabe der Erfindung, Absperrschieber der vorausgesetzten Art in der Weise zu verbessern, daß die Absperrplatten sowohl beim Bewegen in die Schließstellung als auch beim Bewegen in die Offenstellung ohne Berührung mit den Gehäusewandteilen bleiben.Gate valve with two parallel shut-off plates held in a support ring The invention relates to a gate valve with two parallel shut-off plates, which is held in a support ring and arranged to be movable only perpendicular to the spindle axis are. In the case of gate valves with these embodiments, there is the difficulty the shut-off plates in the closed position and out of it with the least possible friction to move between the housing and the shut-off plates and at the same time a safe one Ensure completion. In the known embodiments, the shut-off plates are by means of a lever mechanism in a non-positive connection with each other. When moving the locking device in the open position is the one carrying the shut-off plates Ring on the housing. When moving into the closed position occurs as a result of the lever arrangements on the spindle a concern of the shut-off plates on the housing, so that a there is additional friction. It is therefore the object of the invention to provide gate valves of the presupposed type in such a way that the shut-off plates improve both when moving into the closed position as well as when moving into the open position without Contact with the housing wall parts remain.

Die Erfindung vereinigt zur Lösung der gestellten Aufgabe die folgenden, im wesentlichen bekannten Maßnahmen, nämlich: a) die die Absperrplatten auseinanderspreizenden, an der Spindel aufgehängten keilförmigen Druckstöcke stützen sich über eine frei schwebende Kugel ab, und b) zwischen die Spirnflächen der Absperrplatten und einen Spindelbund ist eine Feder eingespannt.The invention combines the following to solve the problem posed, essentially known measures, namely: a) the spreading of the shut-off plates, Wedge-shaped printing blocks suspended from the spindle are freely supported by a floating ball from, and b) between the end faces of the shut-off plates and a A spring is clamped in the spindle collar.

Der Erfindungsgegenstand ist auf der Zeichnung in einer beispielsweisen Ausführungsform schematisch im Längsschnitt dargestellt.The subject of the invention is shown on the drawing in an exemplary manner Embodiment shown schematically in longitudinal section.

Die beiden Absperrplatten 1, 2 haben eine planparallele Ausgestaltung. Sie werden durch zwei Druckstücke 3 auseinandergespreizt. Die Absperrplatten 1, 2 und die Druckstücke 3 haben für die Spreizwirkung gemeinsame Keilflächen 4. Die Druckstücke 3 stützen sich gegeneinander über eine freischwebende Kugel 5 ab und sind auf dem kantigen Ende 7 der Spindel 8 aufgeschoben.The two shut-off plates 1, 2 have a plane-parallel design. They are spread apart by two pressure pieces 3. The shut-off plates 1, 2 and the pressure pieces 3 have common wedge surfaces 4 for the spreading effect Pressure pieces 3 are supported against one another via a free-floating ball 5 and are pushed onto the angular end 7 of the spindle 8.

Die Absperrplatten 1, 2 sind in einen Tragring 15 eingeschoben, der ein Leitrohr 16 trägt. Der Tragring 15 stößt in der Schließstellung mit einer Fläche 17a gegen einen Anschlag 17b des Gehäuses 18. Zwischen den unteren Stirnflächen 19 der Druckstücke 3 und den gegenüberliegenden Flächen 20 an den Absperrplatten 1, 2 ist ein Spielraum 21 belassen. Das hat zur Folge, daß in der Schließstellung die Spindel 8, 7 über die Druckstücke 3, 4 die Absperrplatten 1, 2 sowie den Tragring 15 gegen das Gehäuse drückt. Auf diese Weise entsteht eine Spreizwirkung. Um diese Spreizwirkung nicht vorzeitig, d. h. bereits beim Zufahren der Absperrplatten 1, 2 eintreten zu lassen, ist zwischen der Schieberspindel 8 und den Absperrplatten 1, 2 eine Feder 22 eingesetzt. Diese Feder 22 stützt sich gegen die Absperrplatten 1, 2 und einen Bund 23 an der Spindel 8 ab. Ihre Spannkraft wird erst dann überwunden, wenn sich in der Schließstellung der Absperrplatten 1, 2 die Tragringfläche 17 a gegen den Gehäuseanschlag 17 b stützt. Es hat sich als besonders vorteilhaft herausgestellt, die Feder 22 durch eine Säule aus Tellerfedern zu bilden. Die zwischen dem Spindelbund 23 und den Absperrplatten 1, 2 vorgesehene Federsäule 22 hat die Wirkung, daß die Absperrplatten 1, 2 zwischen der Schließstellung und der Öffnungsstellung ständig von ihren Dichtungssitzen frei vom Reibungsschluß gehalten werden. Das hat zur Folge, daß bei starken Verunreinigungen der Dichtungsflächen oder bei hohen Leitungsdrücken die Absperrplatten sich leicht zwischen ihren Dichtungssitzen bewegen lassen.The shut-off plates 1, 2 are pushed into a support ring 15 which carries a guide tube 16. In the closed position, the support ring 15 abuts with a surface 17a against a stop 17b of the housing 18. A clearance 21 is left between the lower end surfaces 19 of the pressure pieces 3 and the opposing surfaces 20 on the shut-off plates 1, 2. As a result, in the closed position, the spindle 8, 7 presses the shut-off plates 1, 2 and the support ring 15 against the housing via the pressure pieces 3, 4. This creates a spreading effect. In order not to allow this spreading effect to occur prematurely, ie already when the shut-off plates 1, 2 are being closed, a spring 22 is inserted between the slide spindle 8 and the shut-off plates 1, 2. This spring 22 is supported against the shut-off plates 1, 2 and a collar 23 on the spindle 8. Your clamping force is only overcome when, in the closed position of the shut-off plates 1, 2, the support ring surface 17 a is supported against the housing stop 17 b. It has been found to be particularly advantageous to form the spring 22 by a column of disc springs. The spring column 22 provided between the spindle collar 23 and the shut-off plates 1, 2 has the effect that the shut-off plates 1, 2 are kept free of frictional engagement by their sealing seats between the closed position and the open position. As a result, if the sealing surfaces are heavily contaminated or if the line pressures are high, the shut-off plates can easily be moved between their sealing seats.
