KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es sind bereits Gasschieber bekannt, bei denen der Absperrschieber in der Offenstellung in einer unterhalb des Gasrohres angebrachten Nische gelagert ist; bei diesen Einrichtungen ist indessen die Spindel zum Antrieb des Schiebers oberhalb des letzteren gelagert. Versuche des Erfinders haben ergeben, daß hierbei die Undichtigkeiten des Gasschiebers nicht durch den abgesetzten Teer, derGas valves are already known in which the gate valve is in the open position is stored in a niche attached below the gas pipe; at these facilities meanwhile, the spindle for driving the slide is mounted above the latter. Experiments by the inventor have shown that this is where the gas valve leaks not by the settled tar that
ίο sich zwischen den Spiegel des Schiebers und das Schiebegehäuse setzt, verursacht wird, sondern daß die festen teerigen Bestandteile ein Hindernis beim Drehen der Antrieb spin del des Schiebers in seiner Gewindemutter bilden.ίο between the mirror of the slider and the sliding housing sets, is caused, but that the solid tarry components form an obstacle when turning the drive spin del of the slide in its threaded nut.
Um diesen Ubelstand zu vermeiden, ist nach der Erfindung auch die Antriebspindel des Schiebers und dessen Gewindemutter in die untere Nische des Schiebergehäuses verlegt.In order to avoid this Ubelstand, the drive spindle of the Slide and its threaded nut moved into the lower niche of the slide valve housing.
Auf der Zeichnung ist die Vorrichtung inIn the drawing the device is in
ao Fig. ι und 2 zur Darstellung gebracht.ao Fig. ι and 2 brought to the representation.
Die Gewindegänge der Antriebspindel c und der Gewindemutter d werden dadurch gangbar gehalten, daß dieselben ständig in einer teerigen Flüssigkeit gelagert sind, so daß ein Austrocknen des Teeres vermieden wird. Zu diesem Zweck ist die Spindel in die Nische e des Ventilgehäuses α verlegt, die auch in bekannter Weise den Schieber bei geöffneter Stellung aufnimmt. Die im Stadtrohrnetz sich ansammelnde teerhaltige!Flüssigkeit überfüllt den Ausbau c, so daß die Gewindegänge der Spindel c und der Mutter i]immer mit der Flüssigkeit in Berührung kommen und dadurch ein sicheres Schließen des Gasschiebers gewährleisten.The threads of the drive spindle c and the threaded nut d are kept passable in that they are constantly stored in a tarry liquid, so that the tar is prevented from drying out. For this purpose, the spindle is moved into the niche e of the valve housing α , which also receives the slide in the open position in a known manner. The tar-containing liquid that collects in the city pipe network overflows the extension c, so that the threads of the spindle c and the nut i] always come into contact with the liquid and thereby ensure that the gas valve closes reliably.
