Description

DEUTSCHESGERMAN

Die Erfindung betrifft einen hydraulischen Grubenstempel und ähnliche Stützvorrichtungen, deren Druckraum mit einem Überdruckventil und einem als Rückschlagventil ausgebildeten Füllventil ausgerüstet ist. Die Unterbringung dieser Ventile muß auf engstem Raum erfolgen. Zudem spielt die Kostenfrage bei hydraulischen Grubenstempeln eine besonders wichtige Rolle, da die Lebensdauer dieser Stempel nicht besonders groß ist. Aus diesem Grunde wird angestrebt, die Einbauten im hydraulischen Stempel möglichst einfach zu gestalten.The invention relates to a hydraulic pit ram and similar support devices, their pressure chamber is equipped with a pressure relief valve and a filling valve designed as a check valve. These valves must be accommodated in a very small space. In addition, the question of costs plays a role Hydraulic pit rams play a particularly important role, since the service life of these rams is not particularly good is great. For this reason, the aim is to make the built-in components in the hydraulic ram as simple as possible to design.

Die Erfindung hat sich nun die Aufgabe gestellt, eine Ventilkombination zu schaffen, die einerseits auf engstem Raum unterzubringen und andererseits im wesentlichen aus einfachen Automatendrehteilen herzustellen ist.The invention has now set itself the task of creating a valve combination that on the one hand To accommodate the tightest space and, on the other hand, to produce essentially from simple automatic turned parts is.

Dies wird erfindungsgemäß durch Vereinigung des erwähnten Überdruckventils mit dem Füllventil zu einer baulichen Ventileinheit erreicht. Zu diesem Zweck erhält der Ventilkörper des Überdruckventils einen rohrförmigen Ansatz, in dessen Hohlraum das Füllventil angeordnet ist, wobei dieser Hohlraum über Durchtrittsöffnungen im Ventilteller des Überdruckventils mit dem Druckraum in Verbindung steht.According to the invention, this is achieved by combining the above-mentioned pressure relief valve with the filling valve a structural valve unit achieved. For this purpose, the valve body receives the pressure relief valve a tubular extension, in the cavity of which the filling valve is arranged, this cavity In connection with the pressure chamber via passage openings in the valve disk of the pressure relief valve stands.

In der Zeichnung ist schematisch ein Ausführungsbeispiel des vereinigten Überdruck- und Füllventils gemäß der Erfindung im Längsschnitt dargestellt.In the drawing is a schematic embodiment of the combined pressure and filling valve shown according to the invention in longitudinal section.

Der Druckraum 1 des Gehäuses 2 ist im Boden durch ein einschraubbares Dehnstabventil abgedichtet, das als Überdruckventil arbeitet. Dieses besteht aus dem Einschraubende 3, dem Schaft 4 und dem Ventilteller 5. Das Einschraubende 3 besitzt einen Vierkant? zum Einstellen der gewünschten Ventilspannung. Der Ventilteller 5 weist einen rohrförmigen Fortsatz 5' auf, auf den ein Rohrnippel 6 aufgeschraubt ist. Im Innern des rohrförmigen Ansatzes 5' ist das als Füllventil dienende Rückschlagventil 9 angeordnet, das durch die Feder 8 belastet ist. Die Ringschulter 6' im Rohrnippel 6 ist als Ventilsitz ausgebildet. Der Hohlraum 10 steht über Durchtrittsöffnungen 11, welche im Ventilteller 5 vorgesehen sind, mit dem Innern des Druckraumes 1 in Verbindung.The pressure chamber 1 of the housing 2 is sealed in the bottom by a screw-in expansion rod valve, that works as a pressure relief valve. This consists of the screw-in end 3, the shaft 4 and the valve disc 5. The screw-in end 3 has a square? to set the desired valve voltage. The valve disk 5 has a tubular extension 5 'onto which a pipe nipple 6 is screwed is. In the interior of the tubular extension 5 ', the non-return valve 9 serving as a filling valve is arranged, which is loaded by the spring 8. The annular shoulder 6 'in the pipe nipple 6 is designed as a valve seat. Of the Cavity 10 is on through openings 11, which are provided in the valve disk 5, with the Inside the pressure chamber 1 in connection.

Die Wirkungsweise der erfindungsgemäßen Ventilkombination ist folgende:The mode of operation of the valve combination according to the invention is as follows:

Der Druckraum 1 wird durch Anschließen eines Schlauches am Nippel 6 durch das Rückschlagventil 9 hindurch gefüllt. Beim Ansteigen des Druckes über ein zulässiges Maß hinaus dehnt sich der Schaft 4 des Dehnstabventils ein wenig, so daß der Ventilteller 5 sich etwas von seinem Sitz abhebt. In dieser Ventilstellung entweicht Druckflüssigkeit so lange nach außen, bis der normale Betriebsdruck wiederhergestellt ist.The pressure chamber 1 is opened by connecting a hose to the nipple 6 through the check valve 9 filled through. When the pressure rises above a permissible level, the shaft 4 of the expands Expansion rod valve a little, so that the valve plate 5 lifts slightly from its seat. In this valve position hydraulic fluid escapes to the outside until normal operating pressure is restored is.

Die Zeichnung veranschaulicht, daß beide Ventile zusammen aus nur drei Automatendrehteilen sowie einer Schraubenfeder bestehen und nicht mehr Platz beanspruchen als bisher das Überdruckventil allein. Die bauliche Ventileinheit läßt sich überdies leicht ein- und ausbauen.The drawing illustrates that both valves are made up of only three automatic turned parts as well consist of a coil spring and do not take up more space than the pressure relief valve alone. The structural valve unit can also be easily installed and removed.
