Description
Kraftabhängige Schaltung für hilfsmittelgesteuerte Armaturen mit mechanischem Kraftwandler.Force-dependent switching for auxiliary-controlled fittings with mechanical Force converter.
Die Erfindung betrifft die kraftabhängige Schaltung'von Antrieben zur Patentanmeldung P 2025 300.3, Gegenstand der Hauptanmeldung P 2025 300.3 ist eine hilfsmittelgesteuerte Armatur mit mechanischem Kraftwandler. Der mechanische Kraftwandler hat die Aufgabe, die vom hilfsmittelgesteuerten Antrieb abgegebene Kraft so zu erhöhen und auf die Ventilspindel zu übertragen, daß deren höchste Kraft beim Schließen des Durchflußquerschnittes zur Verfügung steht.The invention relates to the force-dependent switching of drives for patent application P 2025 300.3, the subject of main application P 2025 300.3 an auxiliary-controlled valve with a mechanical force converter. The mechanical one The task of the force converter is to take the output from the auxiliary drive To increase the force and to transmit it to the valve spindle that its highest force is available when closing the flow cross-section.
Der als Kniehebelgetriebe ausgeführte Kraftwandler stützt sich auf einem mittels Säulen an der Armatur befestigten Joch ab. Somit wirkt am Joch eine Kraft die ebenso groß ist wie die Spindelkraft. Erreicht der Verschlußkörper in Schließstellung seine Endlage in der Armatur und wird durch die Ventilspindel angepresst, so erreicht die Gegenkraft am Joch ihren Höchstwert.The force converter, designed as a toggle mechanism, rests on it a yoke attached to the armature by means of pillars. Thus one acts on the yoke Force that is just as great as the spindle force. If the closure body reaches in Closed position its end position in the valve and is pressed by the valve spindle, so the counterforce at the yoke reaches its maximum value.
Nach vorliegender Erfindung wird das Joch federnd an den Säulen befestigt. Die Federn können so vorgespannt werden, daß das Joch erst dann von seiner festen Anlage abhebt, wenn die auf das Joch wirkend Kraft die eingestellte Vorspannkraft überschreitet.According to the present invention, the yoke is resiliently attached to the pillars. The springs can be pretensioned so that the yoke is only then released from its fixed position The system lifts when the force acting on the yoke exceeds the set pre-tensioning force exceeds.
Mit der Bewegung des Joches können Schalter betätigt werden, die die Zufuhr der Hilfsenergie zum Antrieb abschalten. Somit kann der Antrieb kraftabhängig abgeschaltet werden, wenn am Verschlußkörper eine der Federvorspannkraft gleich große Widerstandskraft überschritten wird.With the movement of the yoke switches can be operated that the Switch off the supply of auxiliary energy to the drive. Thus, the drive can be force-dependent be switched off when one of the spring preload force is equal to the closure body great resistance is exceeded.
Die zum Schalten erforderliche Bewegung kann beispielsweise auch dadurch erreicht werden, daß nicht das.Joch gegenüber den Säulen, sondern die Aufhängepunkte des Kniehebelgetriebes gegenüber dem Joch federn.The movement required for switching can also be achieved, for example can be achieved that not the yoke opposite the pillars, but the suspension points of the toggle mechanism against the yoke.
Die Schaltung des Antriebes in Offenstellung wird vorteilhaft durch wegabhängige Endschalter in an sich bekannter Weise erreicht.Switching the drive to the open position is advantageous travel-dependent limit switch reached in a known manner.
Es wäre aber auch möglich, die kraftabhängige Schaltung sowohl in Schließstellung als auch in Offenstellung vorzusehen, was beispielsweise bei Ventilen mit Rückdichtung, das ist eine Abdichtung zwischen Innenraum der Armatur und Stopfbuchsraum, die durch Aufsetzen des Ventilkegels am Stopfbuchskörper erreicht wird, notwendig ist.But it would also be possible to use the force-dependent circuit in both Provide closed position as well as in open position, what for example at Valves with a back seal, that is a seal between the interior of the valve and stuffing box space, which is reached by placing the valve cone on the stuffing box body is necessary.
Nachstehend wird die Erfindung anhnad des schematischen Ausführungsbeispieles näher erläutert.In the following, the invention is based on the schematic embodiment explained in more detail.
Fig. 1 zeigt einen mechanischen Kraftwandler im Schnitt, beispielsweise mit elektrischem Antrieb.Fig. 1 shows a mechanical force transducer in section, for example with electric drive.
Gemäß Fig. 1 sind die Säulen 1 starr mit der Armatur verbunden.According to FIG. 1, the columns 1 are rigidly connected to the fitting.
Auf den Kontermuttern 3 ist das Joch 4 angelegt und wird durch die Federn 5 angedrückt.On the lock nuts 3, the yoke 4 is applied and is through the Springs 5 pressed.
Entsteht an der Spindel 6 eine Kraft, die hoher ist als die Vorspannung der Federn 5, so wird über das Kniehebelgetriebe 7 das Joch 4 von den Kontermuttern 3 abgehoben, Mit dieser Bewegung kann am Schalter 8 ein Kontakt ausgelöst werden, der beispielsweise den Antrieb 9 ausschaltet. Mit den Kontermuttern 10 kann die Kraft eingestellt werden, bei der der Schalter 8 betätigt werden soll.If there is a force on the spindle 6 that is higher than the preload of the springs 5, the yoke 4 is removed from the lock nuts via the toggle lever mechanism 7 3 lifted, with this movement a contact can be triggered on switch 8, which switches off the drive 9, for example. With the lock nuts 10, the Force can be set at which the switch 8 is to be operated.
