Description
DEUTSCHESGERMAN
Insbesondere bei Keilschiebern ist der Bewegungswiderstand aus der Schließstellung heraus größer als der Widerstand während-der übrigen Betätigung. Um insbesondere den Öffnungsvorgang und die Widerstände der Bewegungen aus der Schließstellung heraus und während der Betätigung auszugleichen, sind verschiedene Mittel bekanntgeworden. So ist es beispielsweise bekannt, den Flüssigkeitsdruck zu Beginn des Öffnungsweges durch erhöhte Arbeitsleistung der Flüssigkeitspumpe zu vergrößern. In einem weiteren Vorschlag wird dem Öffnungsweg ein Kraftspeicher entgegengesetzt, so daß mit wachsender Spannung des Kraftspeichers eine Verzögerung der Geschwindigkeit des Antriebskolbens eintritt. Auch wurde vorgeschlagen, zur Verzögerung des Öffnungsweges einen Servomotor einzuschalten. Alle bekannten Ausführungsformen haben eine verwickelte Konstruktion und benötigen zusätzliche Teile wie Kraftspeicher u. dgl., die zu Betriebsstörungen führen können.In the case of wedge valves in particular, the resistance to movement from the closed position is greater than the resistance during the rest of the actuation. In particular about the opening process and the resistances to compensate for movements out of the closed position and during actuation, various means have become known. For example, it is known to increase the fluid pressure To enlarge the beginning of the opening path through increased work performance of the liquid pump. In Another suggestion is opposed to the opening path of an energy storage device, so that with increasing Voltage of the energy store occurs a delay in the speed of the drive piston. Even it was proposed to switch on a servomotor to delay the opening path. All known Embodiments are intricate in construction and require additional parts such as energy accumulators and the like, which can lead to malfunctions.
Schließlich wurde noch vorgeschlagen, bei einem Ventil die mittels eines Servomotors zum Schließen ausgeübte Kraft während der Betätigung durch einen Regeleingriff zu vermindern. Dabei ist vorgesehen, daß die Zuleitung für das Druckmittel abgesperrt und gleichzeitig die Ablaufleitung geöffnet werden kann. Auch diese Vorrichtung ist durch die Verwendung mehrerer zusätzlicher Teile aufwendig.Finally, it was also proposed that a valve be closed by means of a servomotor to reduce the force exerted during actuation by means of a control intervention. It is provided that that the supply line for the pressure medium can be shut off and the drain line can be opened at the same time. This device is also complex due to the use of several additional parts.
Die Erfindung geht aus von der zuletzt genannten Vorrichtung und hat sich zur Aufgabe gestellt, diese und die bekannten Vorrichtungen dieser Art dadurch zu vereinfachen, daß der Antriebskolben am Ende seiner beiden Hubbewegungen mit einem einstellbaren Druck beaufschlagt wird. Zu diesem Zweck steht der Antriebszylinder zwischen den Endstellungen des Antriebskolbens durch eine Überströmleitung mit einem drucklosen Raum, z. B. der Außenluft, in Verbindung, in die ein Überströmventil eingebaut ist, dessen Ansprechen den Regeleingriff bewirkt. Dieses Überströmventil kann einstellbar sein.The invention is based on the device mentioned last and has set itself the task of this and to simplify the known devices of this type in that the drive piston at the end an adjustable pressure is applied to its two stroke movements. For this purpose stands the Drive cylinder between the end positions of the drive piston through an overflow line a pressureless room, e.g. B. the outside air, in which an overflow valve is installed, whose response causes control intervention. This overflow valve can be adjustable.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel schematisch dargestellt.The invention is shown schematically in the drawing in an exemplary embodiment.
Die Verbindungsstange zwischen dem Verschlußstück 3 und dem Antriebskolben 5 trägt die Kennziffer 1, das Schiebergehäuse die Kennziffer 2. Auf dem Schiebergehäuse 2 befindet sich ein Antriebszylinder 4, in dem sich der Antriebskolben 5 hin und her bewegt. Der Antriebszylinder 4 weist an seinen Enden in bekannter Weise die Ein- und Auslaßkanäle 6 auf, die durch Ventile 6 a bekannter Ausführungsform gesteuert werden.The connecting rod between the locking piece 3 and the drive piston 5 bears the code number 1, the valve housing the code number 2. On the valve body 2 there is a drive cylinder 4 in which the drive piston 5 moves back and forth. The drive cylinder 4 has at its ends in a known manner the inlet and outlet channels 6, which are controlled by valves 6 a known embodiment.
Nach der Erfindung wird in die Wandung des Antriebszylinders 4 zwischen den Ein- bzw. Auslaßkanälen 6 eine Überströmleitung 7 eingesetzt, in die ein regelbares Überströmventil 8 eingebaut ist. DerAccording to the invention, in the wall of the drive cylinder 4 between the inlet and outlet channels 6, an overflow line 7 is used, in which a controllable overflow valve 8 is installed. Of the

Durchgang des Druckmittels durch die Überströmleitung 7 hat die Wirkung, daß der für das Abheben des Verschluß Stücks 3 notwendige Überdruck während der übrigen Betätigung verringert wird. Wenn durch den unteren Einlaßkanal 6 das Druckmittel mit hohem Druck in den Antriebszylinder 4 einströmt, so hebt sich das Verschlußstück 3 von seinem Sitz ab und bewegt sich schnell nach oben, bis der Antriebskolben 5 die Überströmleitung 7 überfahren hat. In diesem Augenblick strömt das Druckmittel teilweise durch die Überströmleitung 7 und das sich öffnende Überströmventil 8 ab, so daß der Druck innerhalb des Antriebszylinders 4 so weit verringert wird, daß er dem für die weitere Betätigung erforderlichen entspricht. Im umgekehrten Sinne erfolgt das Schließen.Passage of the pressure medium through the overflow line 7 has the effect that the lift-off of the closure piece 3 necessary overpressure is reduced during the rest of the actuation. When through the lower inlet channel 6, the pressure medium flows into the drive cylinder 4 at high pressure, so lifts the closure piece 3 moves away from its seat and moves quickly upwards until the drive piston 5 the overflow line 7 has passed. At this moment the pressure medium partially flows through the overflow line 7 and the opening overflow valve 8, so that the pressure within the Drive cylinder 4 is reduced so far that it corresponds to that required for further actuation. Closing takes place in the opposite sense.
Auf diese Weise wird erreicht, daß das Druckmittel den Antriebskolben 5 ausschließlich zu Beginn des Öffnens und Schließens einem Höchstdruck aussetzt, der sich während der übrigen Öffnungs- und Schließbewegung verringert. Hierbei tritt das Druckmittel in den Antriebszylinder 4 mit einem konstanten Höchstdruck ein, der der Abhebekraft des Verschlußstücks 3 von seinem Sitz entspricht und über dem Ansprechdruck des Überströmventils 8 liegt.In this way it is achieved that the pressure medium, the drive piston 5 only at the beginning of the Opening and closing exposes a maximum pressure, which is during the rest of the opening and closing movement decreased. Here, the pressure medium enters the drive cylinder 4 with a constant Maximum pressure, which corresponds to the lifting force of the closure piece 3 from its seat and above the Response pressure of the overflow valve 8 is.
Es kommt häufig vor, daß das von dem Verschlußstück 3 abgesperrte Medium das Verschlußstück 3 von seinem Sitz abhebt. Um das vermeiden, wird eine Arretiervorrichtung vorgesehen, die ebenfalls selbsttätig durch das Druckmittel betätigt wird. Auf dem Deckel 9 des Antriebszylinders 4 sitzt ein Zylinder 11.It often happens that the medium blocked by the closure piece 3, the closure piece 3 of stands out from its seat. To avoid this, a locking device is provided, which is also automatic is actuated by the pressure medium. A cylinder 11 is seated on the cover 9 of the drive cylinder 4.
