Description
Vorrichtung zur selbsttätigen Einstellung des pneumatischen Druckes in einer Leitung in Abhängigkeit von einem Betriebswert (Impuls) in einer anderen Leitung oder einem Behälter Die Erfindung betrifft eine Vorrichtung zur selbsttätigen Einstellung des pneumatischen Druck-es in einer Leitun- in Abhängigkeit von einem Betriebswert (Impuls) in einer anderen Leitung oder einem f3chälter. Vorrichtungen dieser Art kommen z. 13. als Druck- oder Temperaturregler zur Anwendung. Sie arbeiten mit einer Düse, deren Ausströmtin- e-eii eine durch den jeweili-en Istwert der Regelung gesteuerte Prallplatte den Steuerdruck beeinflußt.Device for the automatic adjustment of the pneumatic pressure in a line depending on an operating value (pulse) in another line or a container The invention relates to a device for the automatic setting of the pneumatic pressure in a line depending on an operating value (pulse) in a different line or in a container. Devices of this type come z. 13. as a pressure or temperature regulator for use. They work with a nozzle, the outflow of which is influenced by a baffle plate controlled by the respective actual value of the regulation, the control pressure.
Bei den bekannten Reglern dieser Art erfordert die Verstellung des Ungleichförmigkeitsgrades einen Eingriff in den Übertragungsmechanismus, der nicht wälirend des Betriebes der zu regelnden Anlage miiglich ist. Ferner ist mit der Verstellung des Üngleichförtnigkeitsgrades durchweg eine unerwünschte Verschiebung des Istwertes der Regelung verbunden.In the known controllers of this type, the adjustment of the The degree of irregularity does not interfere with the transmission mechanism during the operation of the system to be controlled is possible. Furthermore, with the Adjustment of the degree of unequality is consistently an undesirable shift of the actual value of the control.
Diese Nachteile werden durch die Erfindung beseitigt, deren Kennzeichen darin besteht, daß die Düse auf einem Kreisbogen beweglich ist und die Prallfläche entsprechend dem Radius dieses Kreisbogens gekrümmt und um einen auf dem Kreisbogen liegenden, Punkt schwenkbar ist. Die E.rfindung ertriöglicht die Verstellung des Ungleichförmigkeitsgrades während !des Betriebes, und eine ungewollte Änderung des Istwertes ist mit solchen Verstellungen nicht verbunden.These disadvantages are eliminated by the invention, the characteristics of which consists in the fact that the nozzle and the baffle are movable on an arc of a circle curved according to the radius of this circular arc and around one on the circular arc lying, point is pivotable. The invention enables the adjustment of the Degree of irregularity during operation, and an unwanted change in the Actual values are not associated with such adjustments.
Nach einer Ausführungsform der Erfindung erstreckt sich die Düsenbewegung auf einen Viertelkreisbogen, wenn der Ungleichförmigkeitsgrad von kleinen bis zu großen Werten geändert werden soll. Die zur gedachten LinieDüsendrehpurikt-Prallflächeudrelipunkt spi#egell)ildliclie Düsenbewegung kehrt den Richtungssinn des Regelvorgangs um, wobei dür volle X7erstellbereich des Ungleichfi#rmigkeitsgrades der gleiche ist wie oben.According to one embodiment of the invention, the nozzle movement extends to a quarter of a circle if the degree of irregularity is from small to large values should be changed. The delta point to the imaginary line spi # egell) ildliclie nozzle movement reverses the direction of the control process, where the full range of the degree of inequality is the same as above.
litt erst,un Fall hat malt die Düse öffnend bei steigendein ' Meßwert; im zweiten Fall hat nian die Düse schließend bei steigendem Meßwert.First suffered, and then paints the nozzle opening with increasing a ' measured value; in the second case, nian has the nozzle closing when the measured value increases.
Uni den mittleren Arbeitspunkt einer jeden Keimlinie unabhängig voll der Einstellung des Ungleichii3rini"keitsgrä(l#2s zu machen, ist nach einer weiteren Ausführungsforin de r Erfindung der Prallfl:ichendrelipunkt, vorn Düsen(Irchpunkt ans gesehen, geringfügig in radialer Richtung verschiebhar. Ilicr(Itircli wird es möglich, daß der Istwert Regelung bei mittlerer Last bei Ver:indertilig des Ungleichförrnigkeitsgrades seinen Wert nicht In der Zeichnung ist ein Ausführungsbeispiel des Z, FrIflidungsgegenstandes schematisch dargestellt. , t' t' Der wirkliche Regelwert, z. B. der in einer Rolltleitung herrschende Luftdruck, wirkt über die bewegliche Leitung i auf die Röhrenfeder 2 ein, die bei 14 im Halter 15 drehbar gelagert ist. Das eitle Ende 2" der Röhrenfeder ist an (lern um 14 schwenkbaren Art" 3 befestigt, der mittels der Kurvenscheibe 4 eingestellt werdün kann. Die Kurven-Scheibe 4 dient der Einstellung des Regelwertes. Das andere Ende 2b der Röhrenfeder greift übcr die Zugstange 5 am Gegenarrn 6 einer Prallplatte 7 #l11, die bei 8 schNvenkbar gelagert ist. Die Prallplatte hat die Form eines Ringes. Ihre Innenfläche bewirkt in Zusammenarbeit mit der bei io schwenkbaren Düse 9 die Einstellung der Ungleichförmigkeit. Die Düse ist auf dem Kreisbogen beweglich, den in der gezeichneten Stellung die Innenfläche der Prallplatte 7 bildet. Mit der Düse 9 ist der Zeiger i i verbunden, der über der Skala 12 Spielt. To make the middle working point of each germ line fully independent of the setting of the inequality, according to a further embodiment of the invention of the baffle endreli point, in front of the nozzles (seen from the point of view, it can be shifted slightly in the radial direction. Itircli it is possible that the actual value regulation at medium load at Ver. of Ungleichförrnigkeitsgrades its value is indertilig not in the drawing, an embodiment of Z, FrIflidungsgegenstandes schematically illustrated, t 't' the actual control value, for example, in a. Rolling line prevailing air pressure acts via the movable line i on the tubular spring 2, which is rotatably mounted at 14 in the holder 15. The empty end 2 "of the tubular spring is attached to (learn about 14 pivotable type" 3 , which by means of the cam disk 4 The cam disk 4 is used to set the control value. The other end 2b of the tubular spring engages over the pull rod 5 on the counter arm 6 of a baffle plate 7 # 11, which is pivoted at 8. The baffle plate has the shape of a ring. Its inner surface, in cooperation with the nozzle 9, which can be swiveled at io, adjusts the irregularity. The nozzle can be moved on the arc of a circle which forms the inner surface of the baffle plate 7 in the position shown. The pointer ii, which plays over the scale 12, is connected to the nozzle 9.
Bei einer Vergrößerung des wirklichen Regelwertes vergrößert sich der Ilub der Röhrenfeder 2. Dies bewirkt eine Schwenkung der Prallplatte 7 um ihren Zapfen 8 im Uhrzeigersinn. Die Ausströlnung aus der Düse 9 wird hierdurch größer. Infolgedessen sinkt der Druck in der Leitung 13. Hierdurch wird in an sich bekannter Weise der zu regelnde Druck erliiedrigt, so daß auch der wirkliche Regelwert kleiner wird.When the actual control value is increased, the hub of the tubular spring 2 increases. This causes the baffle plate 7 to pivot about its pin 8 in a clockwise direction. The outflow from the nozzle 9 is increased as a result. As a result, the pressure in the line 13 drops. As a result, the pressure to be regulated is reduced in a manner known per se, so that the actual regulating value also becomes smaller.
Soll die Steuerart gewechselt werden, so wird die Düse 9 um i 8o' geschwenkt. In diesem Fall ergibt sich bei einer Vergrößerung des Federweges eine Verringerung der Ausströrnung aus der Düse, so daß der Druck in der Leitung 13 steigt.If the type of control is to be changed, the nozzle 9 is pivoted through i 8o '. In this case, an increase in the spring travel results in a reduction in the flow out of the nozzle, so that the pressure in the line 13 increases.
Der Schwenk-bereich der Düse 9 wird in der Regel auf 8o bis
85' bemessen. Eine Schwenkung der
