Description
Vorrichtung zur Übertragung zweier Impulskräfte auf die Steuervorrichtung von Reglern Bei der Übertragung zweier. Impulse (z. B. Differenzdrücke, magnetische Kräfte usw.) auf eine Steuervorrichtung eines Reglers ist es oft erforderlich, das Verhältnis der beiden Impulse zueinander in sehr weiten Grenzen regeln zu müssen, z. B. bei Differenzdruckreglern, Gemischtreglern usw. Regeleinrichtungen als solche sind für diese Zwecke bekannt, ihnen haftet. aber der Mangel an, daß der Regelbereich ziemlich eng begrenzt ist und die Einstellung nur linear mit dem Verstellungsweg verändert werden kann.Device for transmitting two impulse forces to the control device of controllers When transferring two. Pulses (e.g. differential pressures, magnetic Forces, etc.) on a control device of a regulator, it is often necessary that To have to regulate the ratio of the two impulses to one another within very wide limits, z. B. with differential pressure regulators, mixture regulators, etc. control devices as such are known for these purposes, they are liable. but the lack of that control range is quite narrow and the setting is only linear with the adjustment path can be changed.
Die Erfindung stellt eine Regelvorrichtung dar, die eine weitgehende Verstellung ermöglicht und bei der das Verhältnis der auf sie wirkenden Kräfte bei gleichem Verstellungsweg wie bei den bekannten Einrichtungen statt einer linearen eine potenzierte Veränderung bewirkt.The invention represents a control device that is a far-reaching Adjustment allows and in which the ratio of the forces acting on them the same adjustment path as in the known devices instead of a linear one causes a potentiated change.
In der Zeichnung ist eine Ausführung beispielsweise dargestellt, und zwär sind a und b zwei Impulsempfänger. Dieselben können z. B. unter dem Einfluß von Gasdrücken stehen. Der Impuls von a wird durch die Druckstange c auf den Hebel e übertragen. Der Impuls von b wird durch die Druckstange d auf den Hebel f übertragen. Der Hebel e hat seinen Drehpunkt bei g, der Hebel f in gleicher Richtung bei la. Der Druck des Hebels e wird durch das Zwischenstück i und der Druck des Hebels f durch das Zwischenstück 1e auf den Relaishebel L der Steuervorrichtung (Relais) übertragen. Der Hebel l reguliert z. B. die Ausflußmündung a eines Reglers bekannter Bauart. Die beiden Zwischenstücke i und 1a sind auf dem Hebel L in entgegengesetzter Richtung verschiebbar, z. B. wie in der Zeichnung angegeben ist, durch eine Schraubenspindel mit Links- und Rechtsgewinde, welche auf den Hebel L aufgesetzt ist und mittels eines Handrädchens m gedreht werden kann.In the drawing, an embodiment is shown for example, and between a and b are two pulse receivers. The same can e.g. B. are under the influence of gas pressures. The momentum from a is transmitted through the push rod c to the lever e. The momentum from b is transmitted through the push rod d to the lever f . The lever e has its pivot point at g, the lever f in the same direction at la. The pressure of the lever e is transmitted through the intermediate piece i and the pressure of the lever f through the intermediate piece 1e to the relay lever L of the control device (relay). The lever l regulates z. B. the outflow mouth a of a known type of regulator. The two intermediate pieces i and 1a can be moved in opposite directions on the lever L, e.g. B. as indicated in the drawing, by a screw spindle with left and right-hand threads, which is placed on the lever L and can be rotated by means of a handwheel m.
Auf diese Weise läßt sich das Verhältnis der Impulskräfte auf den Relaishebel L in weitesten Grenzen verändern.In this way the ratio of the momentum forces to the Change relay lever L as far as possible.
