Zimmermann & Jansen G. m. b. H. in DUren, RhId. Plattenschieber für Gas, Wind, Dampf, Wasser usw. nach Patent 381791.Zimmermann & Jansen G. m. B. H. in DUren, RhId. Knife gate valve for gas, wind, steam, water etc. according to patent 381791.

Zusatz zum Patent 381791.Addendum to patent 381791.

Patentiert im Deutschen Reiche vom 1. Juni 1923 ab. Längste Dauer: 25. April 1940.Patented in the German Empire on June 1, 1923. Longest duration: April 25, 1940.

Zu dem Patent 381791 ist ein Doppelplattenschieber beschrieben, dessen Hauptmerkmal darin besteht, daß die Schieberstange in der Endlage schräg gestellt wird, um die beiden exzentrisch an der Schieberstange aufgehängten Schieberplatten auf ihren Didhtungssitz aufzupressen. Diese Schrägstellung mußte bei dieser Ausführung in einem besonderen Arbeitsgange erfolgen.The patent 381791 has a double plate valve described, the main feature of which is that the slide rod is inclined in the end position to the two slide plates suspended eccentrically on the slide rod on their didhtungssitz to press on. This inclination had to be carried out in a special operation in this version take place.

Die vorliegende Erfindung betrifft nun eineThe present invention now relates to a

Verbesserung dieser Einrichtung insofern, als das Schrägstellen in demselben Arbeitsgange mit dem Senken der Schieberplatten erfolgt.Improvement of this facility insofar as the inclination in the same work process takes place with the lowering of the slide plates.

In der Zeichnung ist* die Vorrichtung gezeichnet. Die Schieberstange ist in diesem Falle gekröpft ausgeführt, und zwar ist der gekröpfte Teil α mit dem geraden Teil b durch den Bolzen c verbunden. Der gekröpfte Teil der Schieberstange hat außerdem zwei Führungsbolzen d und e. Die beiden Führungsbolzen d und e bewegen sich in zwei seitlichen Führungen /. Die letzteren sind am unteren Ende, wie die Zeichnung zeigt, ausgebuchtet. Solange nun der Führungsbolzen e im geraden Teil der Führung läuft, kann durch die Schieberstange α ein Heben und Senken der Schieberplatten g und h vorgenommen werden. Sobald nun die Schieberplatten g- und h ihre Schlußstel-In the drawing * the device is drawn. The slide rod is cranked in this case, namely the cranked part α is connected to the straight part b by the bolt c . The cranked part of the slide rod also has two guide pins d and e. The two guide pins d and e move in two lateral guides /. The latter are bulged at the lower end, as the drawing shows. As long as the guide pin e is running in the straight part of the guide, the slide rod α can raise and lower the slide plates g and h . As soon as the slide plates g and h have reached their final

ao lung erreicht haben, hat der Bolzen e den geraden Teil der Führung / verlassen und den ausgebuchteten Teil erreicht. Gleichzeitig setzt sich der Führungsbolzen d an beiden Seiten auf «einen Anschlag i in der Führung / auf. Es kann also kein weiteres Senken der gekröpften Schieberstange α mehr stattfinden. Infolgedessen findet bei weiterem Senken der geraden Schieberstange b eine Drehbewegung um den Führungsbolzen d statt. Aus der Zeichnung ist ohne weiteres ersichtlich, daß durch diese Bewegung die im Hauptpatent erwähnte seitliche Bewegung der Schieberstange α und dadurch die Anpressung der beiden Schieberplatten g und h auf den Scbiebersitz erfolgt.ao lung, the bolt e has left the straight part of the guide / and reached the bulged part. At the same time, the guide pin d rests on a stop i in the guide / on both sides. So there can be no further lowering of the cranked slide rod α . As a result, if the straight slide rod b is lowered further, a rotary movement about the guide pin d takes place. From the drawing it can be readily seen that this movement causes the lateral movement of the slide rod α mentioned in the main patent and thereby the pressing of the two slide plates g and h onto the slide valve seat.

Eine besondere Ausführungsart der vorliegenden Erfindung ist diejenige, daß eine der beiden Schieberplatten fehlt, in der gezeichneten Ausführung die Platte g. Der Schließdruck wird in diesem Falle nur auf die Schieberplatte h erzeugt, während der sonst von der Platte g aufgenommene Gegendruck nunmehr von den Führungen / aufgenommen wird.A special embodiment of the present invention is that one of the two slide plates is missing, in the embodiment shown the plate g. In this case, the closing pressure is only generated on the slide plate h , while the counterpressure otherwise absorbed by the plate g is now absorbed by the guides /.
