Description

Bei· den bekannten Absperrschiebern mit Schließkeil stehen die Dichtplatten mit dem Keil durch schwalbenschwanz- oder T-nutenförmige Führungsstücke, welche in entsprechend geformte Nuten 'eingreifen, in Verbindung. Diese Art der Führung hat sich im Betrieb, besonders im. Dampfbetrieb bei hohem Druck und hoher Temperatur, als nicht genügend sicher erwiesen, da eine Neigung zum Ecken und Klemmen bei der Schwalbenschwanzführung bemerkbar ist und der Flächendruck an den Führungsflächen unverhältnismäßig hoch ist, was bei dem Aufeinandetrgleiten der Führungsteife beim Öffnen und Schließen leicht ein Fressen verursachen kann. Dem ist bei dem Erfmdungsgegienstand in wirksamer Weise dadurch begegnet, daß der Keil mit Winkelleisten auf jeder Seite eine Art Tasche bildet, in welcher die Dichtplatten stecken. Diese werden also von den Winkelleisten am Rande umfaßt. Sie weisen im Gegensatz zu den vorerwähnten Konstruktionen keine besonderen Führungsteile (Schwalbenschwänze) auf, indem sie in einer gewissermaßen bedeutend vergrößerten T-Nut am Umfang geführt sind, nämlich den durch die Winkelleisten gebildeten Taschen am Keil. Da bei dieser Konstruktion die Führungsflächen reichlich dimensioniert werden können und damit eine sichere Führung erreicht wird, kommt weder ein Ecken und Klemmen noch ein Festfressen der gleitenden Teile durch zu großen Flächendruck in Frage. Ein weiterer Vorteil ist, daß sich die Dichtplatten, obwohl sie geführt sind, frei drehen können. In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt. Es zeigtWith the known gate valves with Locking wedge, the sealing plates with the wedge are dovetailed or T-shaped Guide pieces which engage in correspondingly shaped grooves' in connection. This type of leadership has proven itself in the company, especially in the. Steam operation at high Pressure and high temperature, proved to be insufficiently safe, as there is a tendency for corners and jamming in the dovetail guide is noticeable and the surface pressure on the guide surfaces is disproportionately high, which is when they slide together the guide stiffness when opening and Closing it can easily cause seizure. This is the case with the subject matter of the invention in effectively countered by the fact that the wedge with angle strips on each side one Forms a kind of pocket in which the sealing plates are inserted. So these are from the angle bars embraced on the edge. They show in contrast to the aforementioned constructions no special guide parts (dovetails) by putting them in a kind of way Significantly enlarged T-slot are performed on the circumference, namely the pockets formed by the angle strips on the wedge. Since with this construction the guide surfaces can be given ample dimensions and so that a safe guidance is achieved, there is neither a kinking and jamming nor a seizure of the sliding parts due to excessive surface pressure in question. Another advantage is that the sealing plates, although they are guided, they can rotate freely. In the drawing there is an example Embodiment of the invention shown. It shows

Im Gehäuse 1 befinden sich gegenüberliegend die Sitzringe 2. Auf diese werden beim Schließen des Schiebers vom Keil 3 aus die Dichtungsplatten 4 senkrecht aufgepreßt. Der Schließ druck wird durch Druckflächen am Keil übertragen. In der Verschlußstellung setzen sich die Dichtungsplatten auf Knaggen 6 im Gehäuse auf. Die Dichtplatfeen werden dadurch sicher geführt, daß sie von WinkeEeisten 7 am Keil umfaßt werden. Beim Hochgehen des Keils gleiten die schrägen Führungsflächen 8 dieser Leisten auf den Randflächen der Dichtplatten entlang, und da die Dichtplatten durch Sperrhebel 9 am sofortigen Mithochgehen gehindert sind, werden sie von den Sitzen ab- und nach der Mitte zugedrückt. Auf diese Weise ergibt sich die wagerechte Abhebung der Dichtplatten vor dem. senkrechten Hochgehen.In the housing 1 are located opposite one another the seat rings 2. On these, when the slide is closed from the wedge 3, the Sealing plates 4 pressed on vertically. The closing pressure is achieved by pressure areas on the Transfer wedge. In the closed position, the sealing plates sit on lugs 6 in the housing. The sealing plates are safely guided by the fact that they are WinkeEeisten 7 are included on the wedge. When the wedge goes up, the inclined ones slide Guide surfaces 8 of these strips along the edge surfaces of the sealing plates, and there the sealing plates are prevented from going up immediately by the locking lever 9 push them away from their seats and towards the middle. This is how the horizontal lifting of the sealing plates before. going up vertically.

Die Sperrklinken 9 unterfassen beim Blokkieren der Dichtplatten die Gehäuseleisten 10, während nach beendeter Blockierung die Dichtplatten durch Knaggen 11 am Keil mitgenommen werden. Der Keil ist mit Lappen 12 zwischen senkrechten Gehäuseleisten geführt. The pawls 9 engage under the housing strips 10 when the sealing plates are blocked, while after the end of the blocking, the sealing plates are taken along by lugs 11 on the wedge will. The wedge is guided with tabs 12 between vertical housing strips.
