Description

DEUTSCHESGERMAN

Es sind hydraulisch betätigte Schieber bekannt, deren Schieberplatten längs keilförmiger Flächen aufeinander gleiten und dadurch in der jeweiligen Betriebsstellung gegen die Sitze gepreßt werden. Bei der Betätigung werden die Keilflächen so gegeneinander verschoben, daß die Anpressung aufhört. Dadurch wird die anschließende Bewegung erleichtert. Abgesehen davon, daß die Schieberplatten hierbei sehr aufwendig gebaut sind, sind für die Bewegungen dieser Schieber zwei Kolben erforderlich.There are hydraulically operated slide known whose slide plates along wedge-shaped surfaces on one another slide and are thereby pressed against the seats in the respective operating position. In the When actuated, the wedge surfaces are shifted against each other in such a way that the contact pressure ceases. Through this the subsequent movement is made easier. Apart from the fact that the slide plates are very expensive two pistons are required for the movements of these slides.

Der Erfindung liegt die Aufgabe zugrunde, einen solchen hydraulisch betätigten Absperrschieber zu vereinfachen. Sie besteht darin, daß jeder Schieberplatte mindestens eine Lockerungsschraube zugeordnet ist, die beim Einschrauben ein Abheben der Schieberplatte von ihrem Sitz herbeiführt. Die Lockerungsschrauben sind an ihrem außerhalb des Schiebergehäuses liegenden Teil durch abdichtende, lösbare Kappen umfaßt.The invention is based on the object of simplifying such a hydraulically operated gate valve. It consists in that at least one loosening screw is assigned to each slide plate, which causes the slide plate to lift off its seat when it is screwed in. The loosening screws are enclosed on their part lying outside the valve body by sealing, detachable caps.

Es ist bereits bekannt, bei Hähnen mit konischem Küken Gewindebolzen vorzusehen, die das Küken in den konischen Sitz hineinziehen, um damit eine bessere Dichtung herbeizuführen. Zum Zwecke der Verdrehung des Kükens kann der Gewindebolzen gelöst und das Küken angehoben werden.It is already known to provide threaded bolts in taps with conical plug, which the plug in pull in the conical seat for a better seal. For the purpose of twisting of the plug, the threaded bolt can be loosened and the plug can be lifted.

Die Zeichnung zeigt einen erfindungsgemäßen Schieber im Aufriß und teilweisen Schnitt.The drawing shows a slide according to the invention in elevation and partial section.

In dem Schiebergehäuse 1 sind die beiden Schieberplatten 2 angeordnet, welche in Abschlußstellung an den Sitzen 3 anliegen. Zwischen den beiden Schiebern 2 sind die üblichen Keilmechanismen 4 angeordnet, welchen die Aufgabe zufällt, die beiden Schieber gegen die zugehörigen Sitze 3 zu drücken und damit einen dichten Abschluß zu bewirken. Die beiden Schieberplatten 2 sowie der Teil 4 sind oben durch ein Joch 6 verbunden, an welchem die Schieberstange 5 ansetzt. Diese erstreckt sich durch eine Kammer 7 und ist mit einer Kolbenstange 8 verbunden. Am anderen Ende der Kolbenstange 8 sitzt ein in einem hydraulischen Zylinder 9 geführter, nicht sichtbarer Kolben. Zur Betätigung des Kolbens ist der Zylinder 9 mit Zufluß- und Abflußstutzen 11, 12 versehen.In the slide housing 1, the two slide plates 2 are arranged, which in the final position on the seats 3 rest. The usual wedge mechanisms 4 are arranged between the two slides 2, which the task falls to press the two slides against the associated seats 3 and thus one to bring about a tight seal. The two slide plates 2 as well as part 4 are at the top by a yoke 6 connected to which the slide rod 5 attaches. This extends through a chamber 7 and is with a piston rod 8 connected. At the other end of the piston rod 8 sits a hydraulic one Cylinder 9 guided, not visible piston. To operate the piston, the cylinder 9 is equipped with an inflow and drain nozzles 11, 12 are provided.

Am Boden des Gehäuses 1 ist unter den Schieberplatten 2 ein Sockel 13 angeordnet, in welchem Lockerungsschrauben 14 sitzen. Um ein Durchtreten von Gas durch die Gewindeführungen der Lockerungsschrauben auszuschließen, sind die außerhalb des Sokkels 13 liegenden Teile der Schrauben 14 durch lösbare Kappen 15 abgedeckt.At the bottom of the housing 1, a base 13 is arranged under the slide plates 2, in which loosening screws 14 seated. To prevent gas from passing through the thread guides of the loosening screws excluded, the parts of the screws 14 lying outside the base 13 are detachable Caps 15 covered.

Sitzt eine Schieberplatte 2 auf ihrem Sitz 3 fest, so werden nach Abnahme der Kappen 15 die Lockerungsschrauben 14 nach innen geschraubt. Nach einigen Umdrehungen treten sie in Berührung mit den Schie-Hydraulisch betätigter AbsperrschieberIf a slide plate 2 is firmly seated on its seat 3, the loosening screws are removed after the caps 15 have been removed 14 screwed inwards. After a few turns they come into contact with the sliding hydraulic operated gate valve
