Description

Gegenstand der Erfindung ist ein Absperrschieber für Gas- und Wasserrohrleitungen.The invention relates to a gate valve for gas and water pipelines.

Es ist bereits bekannt, bei solchen Absperrschiebern eine Zeigervorrichtung anzubringen, S und zwar ist bei der bekannten Vorrichtung der Zeiger unmittelbar an der sich verschiebenden Spindel befestigt; diese Zeigervorrichtung ist nur bei über der Erde angebrachten Spindeln zum Verstellen von AbsperrschiebernIt is already known for such gate valves to attach a pointing device, S and that is in the known device the pointer is attached directly to the moving spindle; this pointing device is only used with spindles installed above the ground for adjusting gate valves

ίο anwendbar. Um nun auch bei unter der Erde angebrachten Spindeln die Stellung des Absperrschiebers mittels eines Zeigers an einer Skala sichtbar machen zu können, ist der Zeiger gemäß der Erfindung an einer, an einer Schraubenmutter befestigten, parallel zur Spindel angebrachten Stange befestigt, welche bei der tiefsten Stellung der Schraubenmutter über das Ende des die Spindel umgebenden Schutzrohres hinausragt. Hierdurchίο applicable. In order to adjust the position of the To be able to make the gate valve visible by means of a pointer on a scale is that Pointer according to the invention on one attached to a screw nut, parallel attached to the spindle, which is at the lowest position of the screw nut protrudes beyond the end of the protective tube surrounding the spindle. Through this

so wird erreicht, daß der Zeiger sich ha der Straßenkappe bis in seine Höchststellung unter der Erdoberfläche bewegen kann.in this way it is achieved that the pointer is below the street cap up to its maximum position the earth's surface can move.

Die Schlüsselstange α des unter der Erde angebrachten Absperrschiebers ist mit einem Schutzrohr b umgeben; dieses hat an dem oberen Ende eine Erweiterung, welche es ermöglicht, die für die Bewegung eines Zeigers erforderliche Vorrichtung anzubringen. An dem oberen Ende der Schlüsselstange a befindet sich ein Gewinde, .auf dem sich eine Mutter d (s. Fig. 3) beim Drehen der Spindel auf und ab bewegt. Auf der öffnung des ! Schutzrohres ist ein Deckel g mit Schrauben j (s. Fig. 2) befestigt. An dem Deckel g sind. ! vertikale Führungen c, c angebracht, an welchen j die Mutter d beim Drehen der Spindel α auf j und ab gleitet. In die Mutter d sind parallel 1 zur Spindelachse Rundeisenstängchen e, e ein- : geschraubt, welche durch den Deckel g gehen; die oberen Enden dieser Stängchen sind durch einen Zeiger h verbunden, dessen Stellung mit Hilfe von Marken erkennen läßt, ob der Absperrschieber offen oder geschlossen ist. Die dazwischen liegenden Zeigerstellungen lassen auf die jeweilige Schieberstellung schließen. Die Marken sind an einer an dem Schutzdeckel g befestigten Tafel f angebracht und entsprechend der höchsten bzw. der niedrigsten Zeigerstellung mit der Bezeichnung »zu« bzw. »offen« versehen (s. Fig. 1). Die Straßenkappe ist etwas höher und .auch etwas weiter ausgeführt als gewöhnlich, damit die Zeigervorrichtung darin Platz findet.The key rod α of the gate valve installed underground is surrounded by a protective tube b ; this has an extension at the upper end, which makes it possible to attach the device required for moving a pointer. At the upper end of the key rod a there is a thread on which a nut d (see Fig. 3) moves up and down when the spindle is turned. On the opening of the ! A cover g with screws j (see Fig. 2) is attached to the protective tube. On the lid g are. ! vertical guides c, c attached, on which j the nut d slides up and down when the spindle α is turned. Round iron bars e, e are screwed into the nut d parallel 1 to the spindle axis, which go through the cover g ; the upper ends of these rods are connected by a pointer h , the position of which can be recognized with the help of marks whether the gate valve is open or closed. The pointer positions in between allow conclusions to be drawn about the respective slide position. The marks are attached to a panel f attached to the protective cover g and are labeled "closed" or "open" according to the highest or lowest pointer position (see FIG. 1). The street cap is slightly higher and wider than usual to accommodate the pointing device.
