Description
Zum Absperren von Gas-, Wind-, Wasser-, Dampfleitungen usw. werden in solchen Fällen, wo es sich darum handelt, eine; schnelle Absperrung vorzunehmen, sog. Schnellschlußschieber verwendet. Bei denselben hat sich der Nachteil gezeigt, daß im Anfang der Betätigung, solange der volle Druck auf der Schieberplatte ruht, das Ziehen der Platte nur schwer möglich ist. Anderseits wird nach Aufhebung dieses Druckes die Öffnung zu schnell herbeigeführt, z. B. entstehen in Wind- oder Dampfleitungen leicht Stöße durch plötzlich vollkommenes Öffnen.To shut off gas, wind, water, steam lines etc. are in such Cases where it is a question of; make quick shut-off, so-called. Quick-closing slide used. With the same has shown the disadvantage that in the beginning of the actuation, as long as the full pressure rests on the slide plate, pulling the plate is difficult to achieve. On the other hand, after this pressure is lifted the opening brought about too quickly, e.g. B. arise in wind or steam pipes light bumps from sudden complete opening.
Die vorliegende Erfindung hat den Zweck, diese Nachteile zu vermeiden, und zwar geschieht dies in der Weise, daß mit einem Hilfshebel zuerst ein kurzes Stück geöffnet wird.The present invention aims to obviate these drawbacks, and it does so this in such a way that first a short distance is opened with an auxiliary lever.
ao Laut Zeichnung ist an dem Absperrschieber β der Betätigungshebeln angebracht, die Bewegung des letzteren wird durch Laschen c auf die Schieberstange d übertragen. Unter dieser Hauptbetätigungsvorrichtung befindet sich ein Hilfshebel e, der um den Bolzen / drehbar ist. Das Hebelverhältnis wird zweckmäßig so gewählt, daß mit dem Hilfshebel ein großer Kraftaufwand möglich ist. Durch einen Anschlag g kann der Hub des Hilfshebels begrenzt werden, um einesteils ein Abrutschen des Hebels e von der Stange C1 andernteils ein plötzliches öffnen des ganzen Absperrschiebers zu verhindern. Soll also mit der beschriebenen Vorrichtung der Schieber geöffnet werden, so wird zuerst der Hilfshebel e niedergedrückt, bis er auf dem Nocken g aufliegt. Alsdann ist die Schieberplatte von· ihrem Sitz gelöst, ein Druckausgleich hat unterdessen in dem abgesperrten Teil der Rohrleitung stattgefunden, und es ist leicht möglich, mit dem Hauptr hebel ,b den Schieber vollständig zu öffnen. Zweckmäßig werden die Hebel b und e als Hebelpaare oder je als ein gabelförmiger Hebel ausgebildet, die je beiderseits des Schiebergehäuses angreifen.ao According to the drawing, the actuating lever is attached to the gate valve β; the movement of the latter is transmitted to the slide rod d through tabs c. Under this main operating device there is an auxiliary lever e which is rotatable about the bolt /. The lever ratio is expediently chosen so that a large amount of force is possible with the auxiliary lever. The stroke of the auxiliary lever can be limited by a stop g in order, on the one hand, to prevent the lever e from slipping off the rod C 1, and, on the other hand, to prevent the entire gate valve from suddenly opening. If the slide is to be opened with the device described, the auxiliary lever e is first depressed until it rests on the cam g. Then the slide plate is disengaged from its seat ·, a pressure compensation has occurred meanwhile, in the closed-off part of the pipe, and it is readily possible, with the main r b lever to fully open the valve. The levers b and e are expediently designed as pairs of levers or each as a fork-shaped lever, each of which engages on both sides of the slide valve housing.
