Description
StellorganActuator
Die Erfindung betrifft ein Stellorgan, nämlich Drehkegelventil mit einem Kegelventilgehäuse, an deren Antriebswelle ein Drehkegel mit Kegelsegment einschließlich Kegelansatz befestigt ist, die in beiden Durchflußrichtungen (siehe Figur 1) mit einem Ventilsitzring zusammenwirkt, wobei an dem Drehkegel mittig ein Kegelansatz angeordnet ist, den ein geteilter Ring umgreift und der Drehkegel und der Kegel aus keramischen, nichtmetallischen Werkstoffen oder Hartmetall bestehen.The invention relates to an actuator, namely a rotary cone valve with a cone valve housing, to whose drive shaft a rotary cone with a cone segment including a cone extension is attached, which interacts with a valve seat ring in both flow directions (see Figure 1), wherein a cone extension is arranged centrally on the rotary cone, which is surrounded by a split ring and the rotary cone and the cone are made of ceramic, non-metallic materials or hard metal.
Bei einem Stellorgan mit diesen Merkmalen (DE 36 28 160C2) ist der Kegel der Kugelkalotte mit einer Ringnut versehen, in die der mittig geteilte Ring eingreift, der außen mit einer schrägen Anlageschulter versehen ist. Gegen diese schräge Anlageschulter wird ein Gegenring in die Bohrung des Schwenkbügels eingeschraubt, der mit einem entsprechenden konischen Ansatz versehen ist, so daß der geteilte Ring einmal in die Ringnut und zum anderen gegen die Anlageschulter gepreßt wird. Daraus ergibt sich der Nachteil, daß auf den Kegel eine Kerbwirkung ausgeübt wird, so daß bei einem zu starken Anziehen des Gegenringes der Kegel an der Kugelkalotte abreißen kann. Ein solches Abreißen des Kegels kann auch dadurch entstehen, wenn im eingebauten Zustand hohe Schwingungen auftreten.In an actuator with these features (DE 36 28 160C2) the cone of the spherical cap is provided with an annular groove into which the centrally split ring engages, which is provided with an slanted contact shoulder on the outside. A counter ring is screwed into the hole of the swivel bracket against this slanted contact shoulder, which is provided with a corresponding conical shoulder so that the split ring is pressed into the annular groove on the one hand and against the contact shoulder on the other. This results in the disadvantage that a notch effect is exerted on the cone, so that if the counter ring is tightened too much, the cone can tear off the spherical cap. Such a tearing of the cone can also occur if high vibrations occur when the device is installed.
Ein weiterer Nachteil besteht darin, daß die Montage mit einigen Schwierigkeiten verbunden ist, da hierzu mehrere Teile zusammengefügt werden müssen.Another disadvantage is that assembly is somewhat difficult, as several parts have to be put together.
Der Erfindung liegt die Aufgabe zugrunde, ein Stellorgan der eingangs genannten Art so auszubilden, daß beim Befestigen des Kegelsegments an dem Drehkegel auf den Kegel keine Zugkräfte wirken.The invention is based on the object of designing an actuator of the type mentioned at the beginning in such a way that no tensile forces act on the cone when the cone segment is attached to the rotary cone.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß das Kegelsegment einen sich nach außen erweiternden Konus aufweist, daß der Ring mit einem entsprechenden Konus versehen ist und ein Außengewinde aufweist, mit dem er in den Drehkegel einschraubbar ist.This object is achieved according to the invention in that the cone segment has a cone that widens outwards, that the ring is provided with a corresponding cone and has an external thread with which it can be screwed into the rotary cone.
Eine vorteilhafte Ausführungsform besteht darin, daß der eingeschraubte Ring mit der einen Stirnfläche am Bund des Kegelsegments anliegt.An advantageous embodiment consists in that the screwed-in ring rests with one end face on the collar of the cone segment.
Die Erfindung bringt den Vorteil, daß beim Befestigen des Kegelsegments auf den daran angeordneten Drehkegel keinerlei Kerbwirkung erzeugt wird, so daß das Kegelsegment nicht abreißen kann.The invention has the advantage that when the cone segment is attached to the rotary cone arranged thereon, no notch effect is generated, so that the cone segment cannot tear off.
Die Erfindung wird in der nachfolgenden Beschreibung anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. The invention is explained in more detail in the following description using an embodiment shown in the drawings.

An einem Kegelventilgehäue 1 ist an einer Antriebswelle 2 und einem Lagerzapfen 4 ein Drehkegel 3 angeordnet, an dem ein Kegelsegment 5 mit Kegelansatz 6 angebracht ist. Das Kegelsegment 5 und auch der Kegelansatz 6, dessen Konus 7 sich nach außen hin erweitert, bestehen aus keramischen bzw. nichtmetallischen oder metallischen Werkstoffen.A rotary cone 3 is arranged on a drive shaft 2 and a bearing pin 4 on a cone valve housing 1, to which a cone segment 5 with a cone extension 6 is attached. The cone segment 5 and also the cone extension 6, whose cone 7 widens outwards, are made of ceramic or non-metallic or metallic materials.
Weiterhin besitzt das Kegelsegment 5 zum Kegelansatz 6 hin einen Bund 8.Furthermore, the cone segment 5 has a collar 8 towards the cone extension 6.
Die Kegelsegment 5 liegt in der Schließstellung des Ventils an einem, ebenfalls aus keramischen bzw. nichtmetallischen oder aus Hartmetall bestehenden, Ventilsitzring 15 an, der mit Hilfe eines Halteringes 9 (oder ohne Haltering) und eines Gewinderinges 11 am Gehäuse 1 befestigt ist.In the closed position of the valve, the cone segment 5 rests on a valve seat ring 15, which is also made of ceramic or non-metallic or hard metal, which is attached to the housing 1 by means of a retaining ring 9 (or without a retaining ring) and a threaded ring 11.
Zur Befestigung des Kegelansatzes 6 an dem Drehkegel 3 dient ein in der Mitte gemäß einem Durchmesser geteilter Ring 10, der innen mit einem zum Konus 7 umgekehrten Konus 13 versehen ist und über dem Kegelansatz 6 angeordnet ist. Außen besitzt dieser Ring 10 ein Außengewinde 12, womit der Ring 10 in den Drehkegel 3 eingeschraubt werden kann. In der Halteposition liegt dabei die Stirnfläche 14 des Ringes 10 an dem Bund 8 des Kegelsegments 5 an.A ring 10 divided in the middle according to a diameter is used to fasten the cone extension 6 to the rotary cone 3. The ring 10 is provided on the inside with a cone 13 that is inverted to the cone 7 and is arranged above the cone extension 6. On the outside, this ring 10 has an external thread 12, with which the ring 10 can be screwed into the rotary cone 3. In the holding position, the front surface 14 of the ring 10 rests against the collar 8 of the cone segment 5.
Gleichzeitig liegt das Kegelsegment 5 mit dem Bund 8 an der Fläche des Drehkegels 3 an; durch diese formschlüssige Kombination ist eine Beschädigung (d.h. Bruch) durch Kerbwirkung nicht möglich.At the same time, the cone segment 5 with the collar 8 rests against the surface of the rotary cone 3; this form-fitting combination means that damage (i.e. breakage) due to notch effects is not possible.
Die Durchflußrichtung gemäß den Pfeilen 16 kann wahlweise, wie dargestellt, sein.The flow direction according to the arrows 16 can optionally be as shown.
