Description

Gegenstand des Patents 8o2488 ist ein Kolbenschieber, der hauptsächlich für solche Anwendungszwecke bestimmt ist, in denen der Schieber aus korrosionsfesten Werkstoffen, wie Graphit, imprägnierter Kohle, keramischen Stoffen oder Kunststoffen, bestehen muß. Bei diesem Schieber wird in dem Gehäuse i (vgl. Abbildung) die Abdichtung zwischen dem Kolbenschaft 2 und der Bohrung ja dadurch bewirkt, daß auf den Schaft 2 Spreizringe 4` und 4b aufgeschoben sind, deren Spreizung durch eine ebenfalls auf den Schaft aufgeschobene Büchse 3 hervorgerufen wird. Zu diesem Zweck ist bei dem Schieber nach dem Hauptpatent der Schaft an seiner Spindelseite mit einer Gewindehülse versehen, und diese Hülse preßt die Spreizringe mit der Büchse gegen einen Bund 2a am anderen Schaftende.The subject of the patent 8o2488 is a piston valve that mainly is intended for applications in which the slide is made of corrosion-resistant Materials such as graphite, impregnated carbon, ceramic materials or plastics, must exist. With this slide, the seal is in the housing i (see figure) between the piston skirt 2 and the bore caused by the fact that on the skirt 2 expansion rings 4 'and 4b are pushed on, their expansion by a also sleeve 3 pushed onto the shaft is caused. For this purpose is at the slide according to the main patent, the shaft on its spindle side with a threaded sleeve provided, and this sleeve presses the expansion rings with the sleeve against a collar 2a at the other end of the shaft.

Die den Gegenstand der vorliegenden Erfindung bildende Ausgestaltung dieses Kolbenschiebers besteht nun darin, daß zwischen dem Bu 2a am Schaftende und dem benachbarten Spreizring 4b ein Ring 5 eingelegt ist, der sich in der Schließstellung des Schiebers auf einen Vorsprung 6 in der Bohrung ja aufsetzt, und daß zwischen dem anderen Spreizring 4a und der Gewindehülse 7 auf der Spindelseite des Schaftes eine Büchse 8 aufgeschoben ist, die sich in der öffnungsstellung des Schiebers auf Vorsprünge g an der Spindelhalterung aufsetzt. Dabei hat es sich als zweckmäßig erwiesen, den einzulegenden Ring 5 konisch auszubilden und als Vorsprung, auf den er sich aufsetzt, eine entsprechende konische Verengung der Gehäusebohrung zu benutzen. Durch Drehen der Spindel mittels des Handrades io in der Schließ- und Öffnungsstellung des Schiebers lassen sich zusätzliche Drücke und damit eine zusätzliche Spreizurig der Ringe 4a und 4b erzielen, @so daß beispielsweise plötzlich, auftretende Undichtigkeiten sogleich während des Betriebes in einfacher Weise beseitigt werden können.The embodiment forming the subject of the present invention this piston valve now consists in that between the Bu 2a at the end of the shaft and the adjacent expanding ring 4b, a ring 5 is inserted, which is in the closed position the slide sits on a projection 6 in the bore yes, and that between the other expansion ring 4a and the threaded sleeve 7 on the spindle side of the shaft a sleeve 8 is pushed on, which is in the open position of the slide Protrusions g touches on the spindle holder. It has proven to be useful proven to form the ring to be inserted 5 conically and as a projection on the he sits up to use a corresponding conical narrowing of the housing bore. By turning the spindle with the handwheel io in the closed and open position the slide allows additional pressures and thus an additional spread the rings 4a and 4b achieve, @so that, for example, suddenly occurring leaks can be eliminated in a simple manner immediately during operation.

Diese Bauart der Schieber empfiehlt sich insbesondere dann, wenn sie nicht vollständig aus korrosionsfesten Werkstoffen der eingangs genannten Art bestehen, sondern nur mit einer korrosionsfesten Auskleidung, wie sie in der Abbildung angedeutet ist, versehen sein sollen.This type of slide is particularly recommended when do not consist entirely of corrosion-resistant materials of the type mentioned above, but only with a corrosion-resistant lining, as indicated in the figure is to be provided.

PATENTANSPRÜCHE: i. Kolbenschieber gemäß Patent 802488, bei dem zur Abdichtung zwischen Kolbenschaft und Bohrung auf dem Schaft zwei Spreizringe angeordnet sind, dadurch gekennzeichnet, daß zwischen dem Bund am Schaftende und dem benachbarten Spreizring ein Ringeingelegt ist, der sich in der Schließstellung des Schiebers auf einen Vorsprung in der Gehäusebohrung aufsetzt, und .daß zwischen dem anderen Spreizring und der Gewindehülse auf der Spindelseite des Schaftes eine Büchse aufgeschoben ist, die sich in der Öffnungsstellung des Schiebers auf Vorsprünge an der Spindelhalterung aufsetzt. PATENT CLAIMS: i. Piston valve according to patent 802488, in which two expanding rings are arranged on the shaft for sealing between the piston shaft and the bore, characterized in that a ring is inserted between the collar at the end of the shaft and the adjacent expanding ring which, in the closed position of the slide, rests on a projection in the Housing bore touches, and .that between the other expanding ring and the threaded sleeve on the spindle side of the shaft, a bushing is pushed which, in the open position of the slide, rests on projections on the spindle holder. 2. Kolbenschieber nach Anspruch i, dadurch gekennzeichnet, daß der eingelegte Ring konisch ausgebildet ist und daß als Vorsprung in der Gehäusebohrung eine entsprechende konische Verengung dient.2. Piston valve according to claim i, characterized in that that the inserted ring is conical and that as a projection in the housing bore a corresponding conical constriction is used.
