Description

DEUTSCHESGERMAN

Gegenstand der Erfindung ist ein Absperrschieber mit zwei Absperrplatten, die durch zwei an der Spindel aufgehängte, keilförmige Druckstücke auseinandergespreizt werden. Zum Erreichen einer guten "Einstellung der Absperrplatten gegenüber den Dichtsitzen des Gehäuses wurde vorgeschlagen, die Absperrplatten durch ein zwischen den Platten angeordnetes kugeliges Druckstück an die Dichtsitze des Gehäuses zu drücken. Ferner ist es bekannt, die Absperrplatten an ihren gegenüberliegenden Wandungen als einen Käfig für das Druckstück auszubilden und quer zur Spindelachse mit Stützflächen zu versehen, so daß beim Schließvorgang die Absperrplatten durch die unteren Stützschultern zwischen die Dichtsitze hineingezogen und durch ballige Flächen des Druckstückes gegen die Dichtsitze gepreßt werden.The invention relates to a gate valve with two shut-off plates, which by two on the Spindle suspended, wedge-shaped pressure pieces are spread apart. To achieve a good "Adjustment of the shut-off plates with respect to the sealing seats of the housing was proposed, the shut-off plates by means of a spherical pressure piece arranged between the plates on the sealing seats of the housing to press. It is also known, the shut-off plates on their opposite walls as a To train cage for the pressure piece and to provide transverse to the spindle axis with support surfaces so that During the closing process, the shut-off plates are pulled through the lower support shoulders between the sealing seats and are pressed against the sealing seats by spherical surfaces of the pressure piece.

Gegenüber den bekannten Ausführungsformen unterscheidet sich der Erfindungsgegenstand dadurch, daß die beiden keilförmigen Druckstücke sich gegeneinander über eine frei schwebende Kugel abstützen, auf ao dem kantigen Spindelende aufgeschoben sind und an beiden Stirnseiten Stützflächen haben, die quer zur Spindelachse liegen und mit den Absperrplatten über entsprechende Flächen zusammenwirken, die von den Innenwandungen der die Druckstücke aufnehmenden, einen Käfig bildenden Ausnehmungen in den einander zugekehrten Rückseiten der Absperrplatten gebildet werden.Compared to the known embodiments, the subject matter of the invention differs in that that the two wedge-shaped pressure pieces are supported against each other via a freely floating ball, on ao are pushed onto the angular spindle end and have support surfaces on both ends that are transverse to the spindle axis lie and cooperate with the shut-off plates via corresponding surfaces, which are from the inner walls the recesses that receive the pressure pieces and form a cage in the recesses facing one another Backs of the shut-off plates are formed.

Durch die erfindungsgemäße Ausgestaltung und Anordnung der Spreizteile entstehen gegenüber den bekannten Ausführungsformen Vorteile in verschiedener Hinsicht. So werden beide Absperrplatten nicht nur gleichzeitig und in gleicher Höhe vor ihre Dichtsitze geführt, sondern können sich auch dann durch die Anordnung der Kugel zwischen den beiden keilförmigen Druckstücken der jeweiligen Stellung der Gehäusesitze leicht anpassen. Gleichzeitig wird außerdem der Anpreßdruck auf die Platten nicht punktförmig durch die Kugel, sondern flächig auf die Platten übertragen unter gleichzeitiger Gewähr der Einstellbarkeit auf die Dichtsitze. Außerdem eignet sich der erfindungsgemäß ausgestaltete Schieber insbesondere für große Abmessungen und für den Einbau in waagerechter Lage.The inventive design and arrangement of the expansion parts arise compared to the known embodiments have advantages in several respects. So both shut-off plates are not only performed at the same time and at the same height in front of their sealing seats, but can also then pass through the arrangement of the ball between the two wedge-shaped pressure pieces of the respective position of the Easily adjust housing seats. At the same time, the contact pressure on the plates is also not punctiform by the ball, but transferred over a large area to the plates while ensuring the Adjustability to the sealing seats. In addition, the slide designed according to the invention is particularly suitable for large dimensions and for installation in a horizontal position.

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

Zwei Absperrplatten, die in der Zeichnung die Kennziffern 1 und 2 tragen, werden durch zwei Druckstücke 3 auseinandergespreizt. Diese Druckstücke 3 bestehen aus zwei Keilstücken, die an ihren abgekehrten Seiten mit Keilflächen 4 gegen die Absperrplatten 1 und 2 drücken. An ihren einander zugekehrten Seiten stützen sie sich gegeneinander über eine frei schwebende Kugel 5 ab.Two shut-off plates, which have the code numbers 1 and 2 in the drawing, are replaced by two Pressure pieces 3 spread apart. These pressure pieces 3 consist of two wedge pieces attached to their Press the remote sides with wedge surfaces 4 against the shut-off plates 1 and 2. At their facing one another On the sides, they are supported against one another by means of a freely floating ball 5.

Die Druckstücke 3 weisen eine Verlängerung 6 mit einer Querbohrung auf. Diese Verlängerung 6 ist auf einen Querbalken 7 am Ende der Spindel 8 aufgeschoben. The pressure pieces 3 have an extension 6 with a transverse bore. This extension 6 is on a crossbar 7 is pushed onto the end of the spindle 8.

Die Druckstücke 3 mit ihren Verlängerungen 6 werden in einen Käfig 9 eingesetzt, der von den zugekehrten Flächen der Absperrplatten 1 und 2 gebildet ist. Zwischen den Verlängerungen 6 und den Absperrplatten 1 und 2 ist ein radiales Spiel 10 vorgesehen. Hierdurch wird erreicht, daß bei senkrechtem Einbau des Absperrschiebers die Absperrplatten 1 und 2 beim Einfahren in die Schließstellung mit ihren Flächen 11 an den Stützflächen 12 der Verlängerungen 6 der Druckstücke 3 hängen, so daß die Absperrplatten 1 und 2 die Schließstellung erreichen, ohne daß die Keilflächen 4 an den Absperrplatten anliegen. Erst beim weiteren Einfahren legen sich die am spindelabgewandten Ende der Druckstücke befindlichen Stützflächen 13 gegen entsprechende Flächen 14 der Absperrplatten und ziehen diese in gleicher Höhe weiter unter gleichzeitigem Auseinanderspreizen der Absperrplatten 1 und 2 durch die Druckstücke 3, die sich hierbei auf ihrer gemeinsamen Kugel 5 abstützen. Beim Öffnungsvorgang heben sich zunächst die Druckstücke 3 mit den Keilflächen 4 von den Absperrplatten ab, so daß die Dichtspannung aufgehoben wird und die Absperrplatten sich gegeneinander bewegen können. Erst wenn die Flächen 11 und Stützflächen 12 aneinanderstoßen, beginnt das Ausfahren der Absperrplatten 1 und 2.The pressure pieces 3 with their extensions 6 are inserted into a cage 9, which is facing from the Areas of the shut-off plates 1 and 2 is formed. Between the extensions 6 and the shut-off plates 1 and 2 a radial play 10 is provided. This ensures that when installed vertically of the gate valve the shut-off plates 1 and 2 when moving into the closed position with their surfaces 11 hang on the support surfaces 12 of the extensions 6 of the pressure pieces 3, so that the shut-off plates 1 and 2 reach the closed position without the wedge surfaces 4 resting against the shut-off plates. First as the retraction continues, those located on the end of the pressure pieces facing away from the spindle are placed Support surfaces 13 against corresponding surfaces 14 of the shut-off plates and pull them to the same height further with simultaneous spreading apart of the shut-off plates 1 and 2 by the pressure pieces 3, the support themselves here on their common ball 5. During the opening process, the pressure pieces are initially raised 3 with the wedge surfaces 4 from the shut-off plates, so that the sealing tension is lifted and the shut-off plates can move against each other. Only when the surfaces 11 and support surfaces 12 collide, the shut-off plates 1 and 2 begin to extend.
