Description

Zur Steuerung von Prozessventilen werden häufig pneumatische Stellantriebe (Stellgeräte) eingesetzt, in denen eine auf das Stellglied wirkende Membran mit Hilfe eines gasförmigen Mediums, für das hier im Weiteren allgemein der Begriff "Luft" verwendet wird, mit Druck beaufschlagt und so ausgelenkt wird. Die Druckbeaufschlagung kann einseitig erfolgen, wobei die Membran auf der anderen Seite mit einer Feder belastet ist, oder sie kann zweiseitig erfolgen, wobei unterschiedliche Drücke auf beiden Seiten der Membran die Auslenkung verursachen. Die Regelung der Drücke erfolgt durch einen elektropneumatischen Stellungsregler, in dem ein elektrisch ansteuerbares Ventil unter Druck stehende Zuluft je nach Ansteuerung über zwei Abluftanschlüsse auf die beiden Membranseiten in dem Stellantrieb verteilt.Pneumatic actuators (actuators) are frequently used to control process valves, in which a membrane acting on the actuator is pressurized and thus deflected by means of a gaseous medium, for which the term "air" is generally used here. The pressurization can take place on one side, wherein the membrane is loaded on the other side with a spring, or it can be done on two sides, with different pressures on both sides of the membrane cause the deflection. The regulation of the pressures is carried out by an electropneumatic positioner in which an electrically controllable valve pressurized supply air distributed depending on the control via two exhaust ports on the two sides of the membrane in the actuator.

Die Erfindung geht somit entsprechend dem Oberbegriff des Anspruchs 1 von einem elektropneumatischen Stellungsregler aus, mit einer außen liegenden pneumatischen Schnittstelle, die einen Zuluftanschluss und zwei Abluftanschlüsse zum Anschluss eines pneumatisch antreibbaren Stellgeräts aufweist, und mit einem in dem Stellungsregler angeordneten elektrisch steuerbaren Ventil, das über einen ventileigenen Zuluftanschluss mit dem Zuluftanschluss der Schnittstelle und über zwei ventileigene Steuerluftanschlüsse mit den Abluftanschlüssen der Schnittstelle in Verbindung steht und über die Zuluftanschlüsse zugeführte Druckluft je nach Ansteuerung über die Steuerluftanschlüsse auf die Abluftanschlüsse verteilt.The invention is thus according to the preamble of claim 1 of an electropneumatic positioner, with an external pneumatic interface having a supply air connection and two exhaust ports for connecting a pneumatically driven actuator, and arranged in the positioner with an electrically controllable valve over Depending on the control, compressed air supplied via the supply air connections is distributed to the exhaust air connections via the control air connections to the exhaust air connections.

Stellungsregler bzw. die von ihnen gesteuerten Stellantriebe sind üblicherweise so ausgelegt, dass im Ruhezustand und damit auch bei Ausfall der elektrischen Energie oder der Luftzufuhr das Prozessventil eine vorbestimmte sichere Stellung einnimmt und hält. Je nach Umstand kann es sich bei dieser Sicherheitsstellung um ein geöffnetes oder ein geschlossenes Prozessventil handeln.Positioner or controlled by them actuators are usually designed so that in the idle state and thus also in case of failure of the electrical energy or the air supply, the process valve a predetermined safe position takes and holds. Depending on the circumstances, this safety position may be an open or a closed process valve.

Der Erfindung liegt die Aufgabe zugrunde, mit möglichst einfachen konstruktiven Mitteln die Sicherheitsstellung des Prozessventils an die Erfordernisse des Prozesses anpassen zu können.The invention has for its object to be able to adapt to the requirements of the process with the simplest possible design means the safety position of the process valve.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass entsprechend dem Kennzeichen des Anspruchs 1 der Stellungsregler über eine innere Schnittstelle für das Ventil mit einem zusätzlichen Zuluftanschluss und zwei zusätzlichen Abluftanschlüssen verfügt, die mit dem Zuluftanschluss und den Abluftanschlüssen der außen liegenden Schnittstelle unmittelbar verbunden sind, dass das Ventil in zwei unterschiedlichen Einbaulagen montierbar ist und dass der zusätzliche Zuluftanschluss und die zusätzlichen Abluftanschlüsse der inneren Schnittstelle und der weitere Zuluftanschluss und die Steuerluftanschlüsse des Ventils in übereinstimmenden Anschlussmustern derart angeordnet sind, dass jeder der beiden Steuerluftanschlüsse des Ventils in den beiden unterschiedlichen Einbaulagen mit jeweils einem anderen der beiden zusätzlichen Abluftanschlüsse der inneren Schnittstelle fluchtend verbunden ist und die Zuluftanschlüsse des Ventils und der inneren Schnittstelle in beiden Einbaulagen des Ventils miteinander fluchtend verbunden sind.According to the invention, this object is achieved in that, according to the characterizing part of claim 1, the positioner has an inner interface for the valve with an additional supply air connection and two additional exhaust connections, which are directly connected to the supply air connection and the exhaust connections of the external interface, the valve can be mounted in two different installation positions and that the additional supply air connection and the additional exhaust connections of the inner interface and the further supply air connection and the control air connections of the valve are arranged in matching connection patterns such that each of the two control air connections of the valve in the two different installation positions each one of the two additional exhaust ports of the inner interface is aligned and the supply air connections of the valve and the inner interface in both A Building layers of the valve are connected in alignment with each other.

Eine Änderung der Sicherheitslage des Prozessventils lässt sich somit durch eine einfache Änderung der Einbaulage des Ventils in dem erfindungsgemäßen elektropneumatischen Stellungsregler herbeiführen. Dazu sind keine zusätzlichen Teile erforderlich; insbesondere müssen keine Rohrverbindungen gelegt bzw. verändert werden, weil die Verbindung zwischen dem Ventil und der innen liegenden Schnittstelle des Stellungsreglers rohrlos ist.A change in the safety position of the process valve can thus be brought about by a simple change in the installation position of the valve in the electropneumatic positioner according to the invention. There are no additional parts required; In particular, no pipe connections must be placed or changed, because the connection between the valve and the internal interface of the positioner is free of tubes.

Zur weiteren Verringerung des konstruktiven Aufwandes sind vorzugsweise der Zuluftanschluss und die Abluftanschlüsse der äußeren Schnittstelle in demselben Anschlussmuster wie die der inneren Schnittstelle angeordnet, so dass die Anschlüsse der inneren Schnittstelle mit den entsprechenden Anschlüssen der äußeren Schnittstelle fluchten.To further reduce the design effort, preferably the supply air port and the exhaust ports of the outer interface are arranged in the same connection pattern as that of the inner interface so that the inner interface ports are aligned with the corresponding outer port ports.

Um die elektrische Verbindung des Ventils mit der Elektronik des Stellungsreglers von der jeweiligen Einbaulage des Ventils weitgehend unabhängig zu machen, können die elektrischen Anschlüsse des Ventils auf einer Seite des Ventils angeordnet sein, deren Lage von der jeweiligen Einbaulage des Ventils unabhängig ist. Alternativ können die elektrischen Anschlüsse in doppelter Ausführung auf zwei Seiten des Ventils angeordnet sein, wobei in jeder der beiden Einbaulagen des Ventils entweder die eine oder die andere der beiden Seiten in ein und dieselbe Richtung zeigt. Schließlich kann die innere Schnittstelle des Stellungsreglers über zwei elektrische Steckverbinderteile in einer derartigen Anordnung verfügen, dass die elektrischen Anschlüsse des Ventils in jeder der beiden Einbaulagen mit einem der beiden Steckverbinderteile verbunden sind.In order to make the electrical connection of the valve with the electronics of the positioner largely independent of the respective installation position of the valve, the electrical connections of the valve can be arranged on one side of the valve, the position of which is independent of the respective mounting position of the valve. Alternatively, the electrical connections can be arranged in duplicate on two sides of the valve, wherein in each of the two mounting positions of the valve, either one or the other of the two sides in one and the same direction. Finally, the inner interface of the positioner may have two electrical connector parts in such an arrangement that the electrical connections of the valve are connected in each of the two mounting positions with one of the two connector parts.

In Abhängigkeit von der Druckluftversorgung ändert das Stellgerät 1 die Schwenkposition oder behält sie bei.FIG. 1 shows an actuating device 1, in this case a pivoting drive, whose current pivoting position can be detected via a rotary shaft 2. On the actuating device 1, a positioner 3 is mounted, which detects the current pivot position of the actuator 1 and depending on an electric valve 4 controls that supplies the actuator 1 via two exhaust ports not shown here with compressed air. Depending on the compressed air supply, the actuator 1 changes the pivot position or retains it.

Der Stellungsregler 3 weist eine außen liegende pneumatische Schnittstelle 5 zur Verbindung mit dem Stellgerät 1 und eine innere Schnittstelle 6 zur Verbindung mit dem Ventil 4 auf.The positioner 3 has an external pneumatic interface 5 for connection to the actuating device 1 and an inner interface 6 for connection to the valve 4.

Figur 2 zeigt den Gehäuseboden 7 des geöffneten Stellungsreglers 3 mit einer Durchführungsöffnung 8 für die Welle 2. Die hier nicht sichtbare äußere Schnittstelle 5 zu dem Stellgerät 1 weist einen Zuluftanschluss zur Zuführung von Druckluft in den Stellungsregler 3 und zwei Abluftanschlüsse auf. Die innere Schnittstelle 6 weist in demselben Anschlussmuster einen zusätzlichen Zuluftanschluss 9 und zwei zusätzliche Abluftanschlüsse 10 und 11 auf, die mit den entsprechenden Anschlüssen der außen liegenden Schnittstelle 5 fluchten. Ferner sind zwei Gewindebohrungen 12 und 13 zur Befestigung des Ventils 4 vorgesehen. Das Ventil 4 enthält in demselben Anschlussmuster wie die innere Schnittstelle 6 einen ventileigenen Zuluftanschluss 14 und zwei weitere Abluftanschlüsse 15 und 16. Das Anschlussmuster ist radialsymmetrisch, wobei der Zuluftanschluss 9 bzw. 14 in der Mitte liegt und die Abluftanschlüsse 10, 11 bzw. die Steuerluftanschlüsse 15, 16 einander diagonal gegenüberliegen. Das Ventil 4 lässt sich also in zwei um 180° zueinander gedrehten Einbaulagen in dem Stellungsregler 3 montieren, wobei in der einen, hier gezeigten Einbaulage der Steuerluftanschluss 15 des Ventils 4 mit dem Abluftanschluss 10 der inneren Schnittstelle 6 und der Steuerluftanschluss 16 mit dem Abluftanschluss 11 fluchtet und in der anderen um 180° gedrehten Einbaulage der Steuerluftanschluss 15 des Ventils 4 mit dem Abluftanschluss 11 der inneren Schnittstelle 6 und der Steuerluftanschluss 16 mit dem Abluftanschluss 10 fluchtet. Elektrische Anschlüsse 17, 18 sind in doppelter Ausführung auf zwei einander gegenüberliegenden Seiten des Ventils 4 vorgesehen, so dass in jeder Einbaulage des Ventils 4 eine der beiden Seiten mit den Anschlüssen 17 bzw. 18 in ein und dieselbe Richtung zeigt. Die elektrische Verbindung des Ventils 4 mit der übrigen, hier nicht gezeigten Elektronik des Stellungsreglers ist somit von der Einbaulage des Ventils 4 unabhängig.Figure 2 shows the housing bottom 7 of the open positioner 3 with a passage opening 8 for the shaft 2. The not visible here external interface 5 to the actuator 1 has an air inlet for supplying compressed air into the positioner 3 and two exhaust ports. The inner interface 6 has, in the same connection pattern, an additional supply air connection 9 and two additional exhaust air connections 10 and 11, which are aligned with the corresponding connections of the outer interface 5. Furthermore, two threaded holes 12 and 13 are provided for fastening the valve 4. The valve 4 contains, in the same connection pattern as the inner interface 6, a valve-own supply air connection 14 and two further exhaust connections 15 and 16. The connection pattern is radially symmetrical, the supply air connection 9 or 14 being in the middle and the exhaust air connections 10, 11 or the control air connections 15, 16 face each other diagonally. The valve 4 can therefore be mounted in two position of orientation rotated by 180 ° in the positioner 3, wherein in the one installation position shown here, the control air connection 15 of the valve 4 with the exhaust port 10 of the inner interface 6 and the control air connection 16 with the exhaust port 11 is aligned and in the other rotated by 180 ° mounting position of the control air port 15 of the valve 4 with the exhaust port 11 of the inner interface 6 and the control air port 16 is aligned with the exhaust port 10.
