Description

Die Erfindung betrifft eine Volumenstromregleranordnung mit einem für den Einbau in eine Lüftungsleitung ausgebildeten Volumenstromregler, der ein rohrförmiges Gehäuse, ein beweglich in dem Gehäuse angeordnetes Drosselelement und eine außen an dem Gehäuse angeordnete Einstelleinrichtung zum Einstellen des Drosselelements aufweist.The invention relates to a volumetric flow regulator arrangement with a volumetric flow controller designed for installation in a ventilation duct, which has a tubular housing, a throttle element movably arranged in the housing and an adjusting device arranged outside the housing for adjusting the throttle element.

Aus EP 2 784 406 A1 ist ein Volumenstromregler der oben genannten Art bekannt, der mit seinem Gehäuse in ein Rohr der Lüftungsleitung einschiebbar ist. Die notwendigen Einstellungen für das Drosselelement müssen vor dem Einbau vorgenommen werden, da der Volumenstromregler nach dem Einbau nicht mehr ohne weiteres oder nur durch erhöhten Montageaufwand zugänglich ist.Out EP 2 784 406 A1 is a volume flow regulator of the above type is known, which is inserted with its housing in a pipe of the ventilation duct. The necessary settings for the throttle element must be made before installation, since the volume flow controller after installation is no longer readily accessible or only by increased installation costs.

Aufgabe der Erfindung ist es, eine Volumenstromregleranordnung zu schaffen, die einen erleichterten Zugang zu dem Volumenstromregler zum Zwecke der Überprüfung, Verstellung und Reinigung auch nach dem Einbau ermöglicht.The object of the invention is to provide a volumetric flow regulator arrangement which allows easier access to the volumetric flow controller for the purpose of checking, adjusting and cleaning even after installation.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Schiebehülse, die in einem Aufnahmeabschnitt den Volumenstromregler verschiebbar aufnimmt und einen sich axial anschließenden Schiebeabschnitt aufweist, der für ein verschiebbares Einsetzen in ein Rohr der Lüftungsleitung ausgebildet ist, wobei die axiale Länge des Schiebeabschnitts größer ist als die axiale Länge des Gehäuses des Volumenstromreglers.This object is achieved by a sliding sleeve slidably receives the volume flow controller in a receiving portion and having an axially adjacent sliding portion which is designed for a displaceable insertion into a pipe of the ventilation duct, wherein the axial length of the sliding portion is greater than the axial length of the housing of the volumetric flow controller.

Beim Einbau wird der Volumenstromregler in den Aufnahmeabschnitt der Schiebehülse eingeschoben, und das Ende mit Schiebeabschnitt wird nur so weit in das Rohr der Lüftungsleitung eingesteckt, dass es um eine Länge, die wenigstens größer ist als die Länge des Gehäuses des Volumenstromreglers, aus dem Rohr herausragt. Das entgegengesetzte Ende am Aufnahmeabschnitt der Schiebehülse wird an ein weiteres Rohr der Lüftungsleitung oder einen Anschlusskasten angeschlossen, der beispielsweise einen Deckenauslass zur Be- oder Entlüftung eines Raumes bildet.When installing the volumetric flow controller is inserted into the receiving portion of the sliding sleeve, and the end with sliding portion is inserted only so far into the pipe of the ventilation duct that it protrudes by a length which is at least greater than the length of the housing of the volumetric flow controller, out of the pipe , The opposite end of the receiving portion of the sliding sleeve is connected to another pipe of the ventilation duct or a junction box, which forms, for example, a ceiling outlet for ventilation of a room.

Wenn nachträglich ein Zugang zu dem Volumenstromregler erforderlich ist, beispielsweise um diesen zu reinigen, so wird die Verbindung zwischen dem Aufnahmeabschnitt der Schiebehülse und dem angrenzenden Rohr bzw. Anschlusskasten gelöst, und die Schiebehülse wird mit ihrem Schiebeabschnitt tiefer in das betreffende Rohr der Lüftungsleitung eingeschoben. Auf diese Weise entsteht in der Lüftungsleitung eine Lücke, durch die der Volumenstromregler entnommen werden kann, nachdem er aus dem Aufnahmeabschnitt der Schiebehülse herausgezogen wurde.If subsequently an access to the volume flow regulator is required, for example, to clean this, the connection between the receiving portion of the sliding sleeve and the adjacent pipe or terminal box is released, and the sliding sleeve is inserted with its sliding portion deeper into the relevant pipe of the ventilation duct. In this way, a gap arises in the ventilation duct, through which the volume flow regulator can be removed after it has been pulled out of the receiving portion of the sliding sleeve.

In Fig. 1 ist ein Teil einer Lüftungsleitung 10 gezeigt, die in einem Deckenhohlraum oberhalb einer abgehängten Decke 12 eines Gebäudes verlegt ist und ein Rohr 14 für die Zufuhr von Zuluft, eine Volumenstromregleranordnung 16 und einen Anschlusskasten 18 aufweist. Der Anschlusskasten 18 ist in die Decke 12 eingelassen und weist an der Unterseite einen Luftauslass 20 auf.In Fig. 1 a part of a ventilation duct 10 is shown, which is laid in a ceiling cavity above a suspended ceiling 12 of a building and a pipe 14 for the supply of supply air, a volume flow regulator assembly 16 and a junction box 18 has. The connection box 18 is embedded in the ceiling 12 and has an air outlet 20 on the underside.

Der Anschlusskasten 18 ist über die Volumenstromregleranordnung 16 luftströmungstechnisch mit dem Rohr 14 verbunden, so dass die über das Rohr 14 zugeführte Zuluft nach unten in den Raum unterhalb der Decke 12 abgegeben werden kann. In der Praxis weist der Luftauslass 20 zumeist Luftleielemente, wie z.B. Drallelemente oder sonstige Ablenkelemente auf, die für eine angemessene Verteilung der Luft sorgen.The connection box 18 is connected via the volumetric flow regulator arrangement 16 to the pipe 14 in terms of air flow, so that the supply air supplied via the pipe 14 can be discharged downwards into the space below the ceiling 12. In practice, the air outlet 20 mostly comprises air-laying elements, such as e.g. Swirl elements or other baffle elements, which ensure an adequate distribution of the air.

Die Volumenstromregleranordnung 16 weist eine Schiebehülse 22 auf, die mit einem Schiebeabschnitt 24 ein Stück weit in das Ende des Rohres 14 eingesteckt ist und in einem im Durchmesser erweiterten Aufnahmeabschnitt 26 einen Volumenstromregler 28 aufnimmt. Das Ende des Aufnahmeabschnitts 26 ist an einen Stutzen 30 des Anschlusskastens 18 angeschlossen. Die Verbindungen zwischen dem Rohr 14 und dem Schiebeabschnitt 24 einerseits und dem Aufnahmeabschnitt 26 und dem Stutzen 30 andererseits sind in bekannter Weise durch Dichtungen 32 abgedichtet.The volume flow regulator assembly 16 has a sliding sleeve 22, which is inserted with a sliding portion 24 a piece far into the end of the tube 14 and a volumetric flow regulator 28 receives in a receiving enlarged diameter portion 26. The end of the receiving portion 26 is connected to a nozzle 30 of the junction box 18. The connections between the tube 14 and the sliding portion 24 on the one hand and the receiving portion 26 and the nozzle 30 on the other hand are sealed in a known manner by seals 32.

Die axiale Länge L1 des Schiebeabschnitts 24 der Schiebehülse 22 ist um so viel größer als die axiale Länge L2 des Volumenstromreglers 28, dass auch der Teil der Schiebehülse 24, der aus dem Rohr 14 herausragt, noch länger ist als der Volumenstromregler 28. Das erlaubt es, den Volumenstromregler 28 auszubauen, indem, wie in Fig. 2 gezeigt ist, die Schiebehülse 22 von dem Anschlusskasten 18 gelöst und tiefer in das Rohr 14 eingeschoben wird. Dadurch entsteht zwischen der Schiebehülse 22 und dem Anschlusskasten 18 eine Lücke mit der Länge L3 (L1 > L3 > L2), die es erlaubt, den Volumenstromregler 28 aus dem Aufnahmeabschnitt 26 herauszuziehen und nach unten zu entnehmen. Um Zugang zu der Schiebehülse 22 und dem Volumenstromregler 28 zu erhalten, wird vorher eine Deckenplatte 34 entfernt, so dass in der Decke 12 eine Öffnung 36 entsteht.The axial length L1 of the sliding portion 24 of the sliding sleeve 22 is so much greater than the axial length L2 of the volume flow controller 28, that even the part of the sliding sleeve 24, which protrudes from the tube 14, is even longer than the volume flow controller 28. This allows to remove the volumetric flow regulator 28 by, as in Fig. 2 is shown, the sliding sleeve 22 is released from the terminal box 18 and inserted deeper into the tube 14. This creates between the sliding sleeve 22 and the junction box 18, a gap with the length L3 (L1>L3> L2), which allows the volume flow controller 28 to pull out of the receiving portion 26 and to remove down. In order to gain access to the sliding sleeve 22 and the volume flow controller 28, a ceiling plate 34 is previously removed, so that in the ceiling 12, an opening 36 is formed.

Der Aufbau des Volumenstromreglers 28 ist in Fig. 3 und 4 näher dargestellt.The structure of the volume flow controller 28 is in 3 and 4 shown in more detail.

In Fig. 3 ist in einem axialen Schnitt ein rohrförmiges Gehäuse 38 des Volumenstromreglers 28 gezeigt. Das Gehäuse 38 hat einen kreisförmigen Querschnitt und ist an seinen entgegengesetzten Enden von umlaufenden Lippendichtungen 39 umgeben, die zur Abdichtung an der Innenwand des Aufnahmeabschnitts 26 dienen. Wenn der Volumenstromregler in den Aufnahmeabschnitt 26 geschoben wird, so werden die Lippendichtungen 39 in der in Fig. 3 gezeigten Weise umgebogen. In dieser Stellung erzeugen die Lippendichtungen eine hohe Haltekraft, wenn der Volumenstromregler in Richtung des Pfeiles A von der Luft angeströmt wird. So wird verhindert, dass der Volumenstromregler durch die Luftströmung mitgenommen wird. Wenn der Volumenstromregler hingegen von Hand aus dem Aufnahmeabschnitt 26 heraus gezogen wird, um Zugang zu der Einstelleinrichtung 50 zu erhalten, so wird auf das Gehäuse 28 eine größere Kraft in Verschieberichtung ausgeübt, mit der Folge, dass die Lippendichtungen 39 in die entgegengesetzte Stellung umschlagen, in der sie der Ausziehbewegung einen geringeren Reibungswiderstand entgegensetzen.In Fig. 3 is shown in an axial section, a tubular housing 38 of the volume flow controller 28. The housing 38 has a circular cross-section and is surrounded at its opposite ends by circumferential lip seals 39, which serve to seal against the inner wall of the receiving portion 26. When the volumetric flow regulator is pushed into the receiving section 26, the lip seals 39 in the in Fig. 3 bent way shown. In this position, the lip seals generate a high holding force when the volume flow controller is flown in the direction of arrow A from the air. This prevents the volumetric flow controller from being taken along by the air flow. If, however, the volumetric flow regulator is pulled out of the receiving section 26 by hand in order to gain access to the adjusting device 50, a greater force is exerted on the housing 28 in the direction of displacement, with the result that the lip seals 39 turn into the opposite position, in which they oppose the pull-out a lower frictional resistance.

Die Umfangswand des Gehäuses 38 bildet im Bereich des oberen Scheitels einen Einzug 40, der den Strömungsquerschnitt lokal verengt. An dem Einzug 40 ist im Inneren des Gehäuses 38 ein Anschlag 42 für ein Drosselelement 44 angeordnet.The peripheral wall of the housing 38 forms an indentation 40 in the region of the upper vertex which locally narrows the flow cross-section. At the feeder 40, a stop 42 for a throttle element 44 is disposed in the interior of the housing 38.

Das Drosselelement 44 hat die Form einer Klappe, die um eine Achse 46 schwenkbar ist, die senkrecht zur Zeichenebene in Fig. 3 durch die Mitte des kreisförmigen Querschnitts des Gehäuses 38 verläuft. Ein Ende der Achse 46 verläuft durch den oberen Teil einer vom Inneren des Gehäuses 38 abgetrennten Kammer 48, die eine Einstelleinrichtung 50 sowie eine Rückstellmechanik als Regelmechanik für das Drosselelement 44 aufnimmt. In Fig. 3 ist eine äußere Abdeckung der Kammer 48 fortgelassen, so dass man in das Innere dieser Kammer blicken kann.The throttle element 44 has the shape of a flap which is pivotable about an axis 46 which is perpendicular to the plane in FIG Fig. 3 passes through the center of the circular cross-section of the housing 38. One end of the axle 46 extends through the upper part of a separated from the interior of the housing 38 chamber 48, which receives an adjustment 50 and a return mechanism as a control mechanism for the throttle element 44. In Fig. 3 an outer cover of the chamber 48 is omitted, so that one can look into the interior of this chamber.

Zu der Rückstellmechanik für das Drosselelement gehören eine Biegefeder 52, die in diesem Beispiel als Blattfeder ausgebildet ist, sowie ein Einstellelement 54, das ebenfalls als Blattfeder ausgebildet ist. Ein oberes Ende der Biegefeder 52 ist starr an der Achse 46 gehalten und schmiegt sich an eine Stützkontur eines Unterstützungskörpers 56 an, der ebenfalls starr an der Achse 46 gehalten ist. Das Einstellelement 54 ist nach Art eines Auslegers an einem Tragkörper 58 gehalten und bildet mit einem klingeartigen freien Ende einen Anschlag 60 für die Biegefeder 52, deren Länge jedoch so bemessen ist, dass sie mit ihrem freien Ende etwas über den Anschlag 60 hinausragt.To the return mechanism for the throttle element include a bending spring 52, which is formed in this example as a leaf spring, and an adjustment member 54, which also is designed as a leaf spring. An upper end of the bending spring 52 is rigidly held on the axle 46 and conforms to a supporting contour of a support body 56, which is also held rigidly on the axle 46. The adjusting member 54 is held on a support body 58 in the manner of a cantilever and forms with a sound-like free end a stop 60 for the bending spring 52, whose length, however, is dimensioned so that it protrudes with its free end slightly above the stopper 60.

Der Tragkörper 58 für das Einstellelement 54 ist um eine Achse 62 drehbar in der Kammer 48 gehalten und mit Hilfe eines Fixierarmes 64 in der jeweils eingestellten Winkelposition fixierbar.The support body 58 for the adjustment member 54 is rotatably supported about an axis 62 in the chamber 48 and fixed by means of a fixing arm 64 in the angular position respectively set.

Fig. 4 zeigt eine Abdeckung 66, die die äußere Verkleidung der Kammer 48 bildet und an der eine Einstellmechanik für den Tragkörper 58 und das Einstellelement 54 angeordnet ist. Die Achse 62 durchsetzt die Abdeckung 66 und trägt auf der Außenseite dieser Abdeckung einen (Außen-) Sechskant 68 und einen Zeiger 70, die beide starr mit dem Tragkörper 58 verbunden sind. Die Konturen des Sechskants 68 und des Zeigers 70 sind auch in Fig. 3 strichpunktiert angedeutet. Fig. 4 shows a cover 66 which forms the outer lining of the chamber 48 and on which an adjustment mechanism for the support body 58 and the adjusting element 54 is arranged. The axis 62 passes through the cover 66 and carries on the outside of this cover a (outer) hex 68 and a pointer 70, both of which are rigidly connected to the support body 58. The contours of the hex 68 and the pointer 70 are also in Fig. 3 indicated by dash-dotted lines.

Der Fixierarm 64 trägt am freien Ende eine Fixierschraube 72, die einen kreisbogenförmigen Schlitz 74 der Abdeckung 66 durchsetzt und es so erlaubt, den Tragkörper 58 und damit das Einstellelement 54 (Fig. 3) in der jeweils gewählten Winkelposition zu fixieren. An der Abdeckung 66 ist eine Skala 76 angebracht, an der mit Hilfe des Zeigers 70 die jeweils gewählte Winkelposition bzw. zugehörig die Sollwertvorgabe für die Strömungsgeschwindigkeit bzw. den Volumenstrom abgelesen werden kann.The fixing arm 64 carries at the free end a fixing screw 72 which passes through an arcuate slot 74 of the cover 66 and thus allows the support body 58 and thus the adjusting element 54 (FIG. Fig. 3 ) in the selected angular position. On the cover 66, a scale 76 is attached, at the indicated angle position or belonging to the setpoint specification for the flow rate or the volume flow can be read using the pointer 70.

Fig. 5 zeigt einen Schnitt durch den Aufnahmeabschnitt 26 der Schiebehülse zusammen mit einer Stirnansicht des Gehäuses 38 mit der im Schnitt dargestellten Kammer 48. Das Drosselelement 44 hat einen annähernd T-förmigen Grundriss, mit seitlichen Aussparungen, von denen eine Platz für die Kammer 48 bereit stellt. Die Aussparung auf der entgegengesetzten Seite (rechts in Fig. 5) stellt Platz für ein weiteres Gehäuse 78 der entgegengesetzten Seite (rechts in Fig. 5) stellt Platz für ein weiteres Gehäuse 78 bereit, in dem beispielsweise ein Dämpfungsmechanismus für das Drosselelement untergebracht sein kann. Am oberen Scheitel ist das Drosselelement 44 um die Höhe des Einzugs 40 gekürzt. An dem Einzug ist der Anschlag 42 zu erkennen, an dem das Drosselelement in der vollständig geschlossenen Stellung mit seinem oberen Rand anschlägt. Fig. 5 shows a section through the receiving portion 26 of the sliding sleeve together with an end view of the housing 38 with the sectioned chamber 48. The throttle element 44 has an approximately T-shaped outline, with lateral recesses, of which a space for the chamber 48 provides. The recess on the opposite side (right in Fig. 5 ) makes room for another housing 78 the opposite side (right in Fig. 5 ) provides space for another housing 78, in which, for example, a damper mechanism for the throttle element can be accommodated. At the upper vertex, the throttle element 44 is shortened by the height of the feeder 40. At the feeder stop 42 can be seen, on which the throttle element strikes in the fully closed position with its upper edge.

Außerdem erkennt man die Einstelleinrichtung 50 in der Kammer 48 sowie den auf der Außenseite der Abdeckung 66 angeordneten Sechskant 68.In addition, it can be seen the adjustment means 50 in the chamber 48 and arranged on the outside of the cover 66 hex 68th

Der Aufnahmeabschnitt 26 der Schiebehülse weist an der Stelle der Einstelleinrichtung 50 eine Revisionsöffnung 80 auf, durch die hindurch der Sechskant 68 sowie auch der Zeiger 70 und die Fixierschraube 72 zugänglich sind. Mit Hilfe eines auf den Sechskant 68 gesteckten Innensechskants 82 kann dann die Winkelstellung des Einstellelements 54 und damit die auf das Drosselelement 44 wirkende Rückstellkraft eingestellt werden. Wenn die Zuluft den Volumenstromregler 28 in Richtung des Pfeils A in Fig. 1 durchströmt, so übt sie auf das Drosselelement 44 ein Drehmoment aus, das die Tendenz hat, dieses in Schließrichtung zu verschwenken. Die Rückstellkraft wirkt diesem Drehmoment entgegen, so dass der Volumenstrom auf einen konstanten Wert geregelt wird, der der Gleichgewichtsposition des Drosselelements 44 entspricht somit von der einstellbaren Rückstellkraft abhängig ist.The receiving portion 26 of the sliding sleeve has at the location of the adjusting device 50 on an inspection opening 80 through which the hex 68 and the pointer 70 and the fixing screw 72 are accessible. With the aid of a hexagon socket 68 inserted on the hexagon 68 then the angular position of the adjusting element 54 and thus the force acting on the throttle element 44 restoring force can be adjusted. If the supply air, the volume flow controller 28 in the direction of arrow A in Fig. 1 flows through, so it exerts on the throttle element 44 a torque which has a tendency to pivot in the closing direction. The restoring force counteracts this torque, so that the volume flow is controlled to a constant value, which corresponds to the equilibrium position of the throttle element 44 thus depends on the adjustable restoring force.

Der Umriss der Revisionsöffnung 80 ist auch in Fig.1 strichpunktiert angedeutet. Da auch der Zeiger 70 durch dies Öffnung sichtbar ist, lässt sich der eingestellte Volumenstrom an der Skala 76 ablesen.The outline of the inspection opening 80 is also in Fig.1 indicated by dash-dotted lines. Since the pointer 70 is visible through this opening, the set volume flow can be read on the scale 76.

Während des Betriebs ist die Revisionsöffnung 80 durch ein Verschlusselement in der Form eines lösbar eingesteckten und abdichtenden Stopfens 84 verschlossen (Fig. 5). In einer anderen Ausführungsform könnte das Verschlusselement auch ein umlaufendes Klebeband sein, dass die Revisionsöffnung überdeckt.During operation, the inspection opening 80 is closed by a closure element in the form of a releasably inserted and sealing stopper 84 (FIG. Fig. 5 ). In another embodiment, the closure element could also be a circumferential adhesive tape covering the inspection opening.

Wenn die Einstellung des Volumenstroms verändert werden soll, braucht lediglich der Stopfen 84 vorübergehend entfernt zu werden. Die Einstellung kann dann verändert werden, ohne dass der Volumenstromregler 28 aus der Schiebehülse 22 entnommen werden muss. Ein vollständiger Ausbau des Volumenstromreglers 28 (wie in Fig. 2) ist deshalb nur dann erforderlich, wenn der Volumenstromregler gereinigt werden soll oder sonstige Wartungsarbeiten vorgenommen werden sollen.If the setting of the volume flow is to be changed, only the plug 84 needs to be temporarily removed. The setting can then be changed without the volume flow controller 28 has to be removed from the sliding sleeve 22. A complete removal of the volumetric flow controller 28 (as in Fig. 2 ) is therefore only required if the volumetric flow controller is to be cleaned or other maintenance work is to be performed.

In Fig. 5 ist weiterhin noch ein Stellmotor 86 gezeigt, der wahlweise - ggf. auch als Nachrüstsatz - an den Aufnahmeabschnitt 26 der Schiebehülse angebaut werden kann. Der Stopfen 84 wird dazu entweder entfernt oder von einem Adapter, z.B. dem Innensechskant 82 des Stellmotors an einer Sollbruchstelle durchstochen, so dass er als Dichtung zwischen dem Stellmotor und dem Aufnahmeabschnitt wirkt. Die Einstelleinrichtung 50 ist dann über den Innensechskant 82 mit der Ausgangswelle des Stellmotors 86 verbunden, so dass die Winkelstellung des Einstellelements 54 und damit der Volumenstrom auch ferngesteuert mit Hilfe des Stellmotors 86 verändert werden kann. Die Fixierschraube 72 wird in diesem Fall gelöst oder ganz entfernt, da der Stellmotor 86 selbst den Sechskant 68 in der jeweils eingestellten Position hält. Bei dem Stellmotor 86 kann es sich um einen Servomotor oder einem Schrittmotor handeln, mit dem sich die Sollposition des Einstellelements und damit der Soll-Volumenstrom präzise vorgeben lässt.In Fig. 5 Furthermore, a servomotor 86 is still shown, which can optionally - be attached to the receiving portion 26 of the sliding sleeve - if necessary, as a retrofit kit. The plug 84 is either removed or pierced by an adapter, for example, the hexagon socket 82 of the servo motor at a predetermined breaking point, so that it acts as a seal between the servo motor and the receiving portion. The adjusting device 50 is then connected via the hexagon socket 82 with the output shaft of the servomotor 86, so that the angular position of the adjusting element 54 and thus the volume flow can also be remotely controlled by means of the servomotor 86. The fixing screw 72 is released or completely removed in this case, since the actuator 86 itself holds the hex 68 in the respectively set position. The servomotor 86 may be a servomotor or a stepper motor, with which the desired position of the adjustment element and thus the desired volume flow can be precisely predetermined.

In einer anderen, hier nicht näher gezeigten Ausführungsform können im Gehäuse 38 des Volumenstromreglers auch Sensoren vorgesehen sein oder nachträglich eingebaut werden, die eine Messung des tatsächlichen Volumenstroms erlauben, beispielsweise Drucksensoren, die den Druckabfall vor und hinter dem Drosselelement messen, oder Strömungssensoren, die unmittelbar die Strömungsgeschwindigkeit messen. Die Sensoren können dann durch die Revisionsöffnung 80 hindurch elektrisch mit einer elektronischen Regeleinrichtung im Gehäuse des Stellmotors 86 verbunden sein, so dass eine rückgekoppelte Regelung des Volumenstroms möglich ist. In diesem Fall kann wahlweise die Funktion der Rückstellmechanik auch umgangen werden, indem man die Ausgangswelle des Stellmotors 86 nicht mit dem Sechskant 68 sondern vielmehr direkt mit der Achse 46 der Drosseleinrichtung 44 verbindet, so dass mit Hilfe des Stellmotors 86 unmittelbar die Klappenblattstellung verändert wird.In another embodiment, not shown here in detail, sensors may also be provided in the housing 38 of the volumetric flow controller or may be retrofitted, which allow a measurement of the actual volumetric flow, for example pressure sensors which measure the pressure drop in front of and behind the throttle element, or flow sensors which directly measure the flow velocity. The sensors may then be electrically connected through the inspection opening 80 with an electronic control device in the housing of the servo motor 86, so that a feedback control of the volume flow is possible. In this case, optionally, the function of the return mechanism can also be circumvented by not connecting the output shaft of the servo motor 86 with the hexagon 68 but rather directly to the axis 46 of the throttle device 44, so that with the help of the servo motor 86 directly the damper blade position is changed.

Während bei den zuvor beschriebenen Ausführungsbeispielen nach Figur 1 und 2 der Volumenstromregler 28 in einer Zuluftleitung angeordnet ist, illustriert Fig. 6 eine Einbauweise, bei der das Rohr 14 eine Abluftleitung bildet, über die Luft durch einen Lufteinlass 88 des Anschlusskastens 18 angesaugt und in Richtung des Pfeils B in Fig. 6 abtransportiert wird.While in the embodiments described above FIGS. 1 and 2 the volume flow controller 28 is arranged in a supply air line, illustrated Fig. 6 an installation in which the tube 14 forms an exhaust duct, sucked through the air through an air inlet 88 of the junction box 18 and in the direction of arrow B in Fig. 6 is transported away.

Der Volumenstromregler 28 ist in diesem Fall in umgekehrter Orientierung eingebaut, so dass die Luft das Drosselelement 44 in derselben Richtung anströmt wie in Fig. 3. Damit die Revisionsöffnung 80 der Schiebehülse 22 (die mit der Schiebehülse nach Fig. 1 baugleich ist) dennoch der Einstelleinrichtung 50 des Volumenstromreglers gegenüberliegt, ist auch die Schiebehülse 22 in Fig. 6 in umgekehrter Stellung eingebaut, so dass ihr Schiebeabschnitt 24 nunmehr zur Seite des Anschlusskastens 18 weist.The volumetric flow controller 28 is installed in this case in the reverse orientation, so that the air flows against the throttle element 44 in the same direction as in Fig. 3 , Thus, the inspection opening 80 of the sliding sleeve 22 (with the sliding sleeve to Fig. 1 is identical) but the adjustment 50 of the flow control is opposite, is also the sliding sleeve 22 in Fig. 6 installed in the reverse position, so that its sliding portion 24 now facing the side of the junction box 18.

An den Stutzen 30 des Anschlusskastens 18 ist deshalb zunächst ein Rohr 90 als Zwischenstück angekuppelt, das die Schiebehülse 24 verschiebbar aufnimmt. Das entgegengesetzte Ende der Schiebehülse 22, also das Ende des Aufnahmeabschnittes 26, ist über einen Steckverbinder 92 mit dem Rohr 14 verbunden. Generell können zur dichten Verbindung der Schiebehülse 22 mit dem Rohr 14 einerseits und mit dem Stutzen 32 andererseits verschiedenste Formen von Steckverbindungen oder auch Flanschverbindungen oder Spannbügelverbindungen vorgesehen sein.To the nozzle 30 of the junction box 18, therefore, a first pipe 90 is coupled as an intermediate piece, which receives the sliding sleeve 24 slidably. The opposite end of the sliding sleeve 22, so the end of the receiving portion 26 is connected via a connector 92 to the pipe 14. Generally can be provided for tight connection of the sliding sleeve 22 with the pipe 14 on the one hand and with the nozzle 32 on the other hand, a variety of forms of connectors or flange connections or clamp connections.

Fig. 7 illustriert eine Variante, bei der die Volumenstromregleranordnung 16 nicht zwischen einem Anschlusskasten 18 und einem Rohr 14 der Lüftungsleitung eingebaut ist, sondern zwischen zwei Rohren 14a und 14b der Lüftungsleitung. Der Schiebeabschnitt 24 der Schiebehülse greift in diesem Fall verschiebbar in das eine Rohr 14a ein, währende der Aufnahmeabschnitt 26 durch den Steckverbinder 92 mit dem anderen Rohr 14b verbunden ist. Fig. 7 illustrates a variant in which the volume flow regulator assembly 16 is not installed between a terminal box 18 and a pipe 14 of the ventilation duct, but between two tubes 14 a and 14 b of the ventilation duct. The sliding portion 24 of the sliding sleeve engages in this case slidably in the one tube 14 a, while the receiving portion 26 is connected by the connector 92 with the other tube 14 b.

Eine Entnahme des Reglers in den Anordnungen nach Fig. 6 und 7 erfolgt analog zu Fig. 2.Removal of the regulator in the arrangements according to 6 and 7 takes place analogously to Fig. 2 ,

Figuren 8 bis 11 illustrieren den nachträglichen Einbau einer Volumenstromregleranordnung in der bestehenden Lüftungsleitung 14. FIGS. 8 to 11 illustrate the retrofitting of a volumetric flow regulator arrangement in the existing ventilation duct 14.

Gemäß Fig. 8 wird in der Decke 12 zunächst eine längere Öffnung 36 gebildet, die Zugang zu einem längeren Abschnitt 14c der Lüftungsleitung 14 gibt. An Trennlinien 94 wird dann der Abschnitt 14c aus der Lüftungsleitung herausgetrennt. In die so entstehende Lücke wird die Schiebehülse 22 eingesetzt, wie in Fig. 9 gezeigt ist. Die ursprüngliche Lüftungsleitung 14 besteht nun aus zwei getrennten Rohren 14a und 14b.According to Fig. 8 In the ceiling 12, a longer opening 36 is initially formed which gives access to a longer section 14c of the ventilation duct 14. At parting lines 94, the section 14c is then separated from the ventilation duct. In the resulting gap, the sliding sleeve 22 is inserted, as in Fig. 9 is shown. The original vent 14 now consists of two separate tubes 14a and 14b.

Wie Fig. 10 zeigt, wird die Schiebehülse 22 mit ihrem Schiebeabschnitt 24 in das Rohr 14a eingeschoben, wodurch zwischen der Schiebehülse und dem Rohr 14b eine Lücke entsteht, in die zunächst ein Steckverbinder 96 eingeführt wird, der dann in das Ende des Rohres 14b eingesteckt wird. Anschließend wird der Volumenstromregler 28 durch die noch verbliebene Lücke hindurch in den Aufnahmeabschnitt 26 der Schiebehülse eingeführt. Wahlweise kann der Volumenstromregler 28 auch schon in dem Aufnahmeabschnitt 26 aufgenommen sein, bevor die Schiebehülse mit ihrem Schiebeabschnitt 24 in das Rohr 14a eingeschoben wird. Danach wird die Schiebehülse 22 zusammen mit den Volumenstromregler in die in Fig. 11 gezeigte Position zurückgezogen, in der sie dicht an den Steckverbinder 96 angeschlossen ist.As Fig. 10 shows, the sliding sleeve 22 is inserted with its sliding portion 24 in the tube 14 a, whereby between the sliding sleeve and the tube 14 b, a gap is formed in the first a connector 96 is inserted, which is then inserted into the end of the tube 14 b. Subsequently, the volumetric flow controller 28 is inserted through the still remaining gap in the receiving portion 26 of the sliding sleeve. Optionally, the volumetric flow controller 28 may also already be accommodated in the receiving section 26 before the sliding sleeve with its sliding section 24 is inserted into the tube 14a. Thereafter, the sliding sleeve 22 together with the volume flow controller in the in Fig. 11 shown withdrawn position in which it is connected to the connector 96 close.

Die Länge des Steckverbinders 96 ist so gewählt, dass die Lücke zwischen den Rohren 14a und 14b auch dann noch überbrückt wird, wenn die Schiebehülse mit ihrem Schiebeabschnitt 24 in das Rohr 14a eingreift.The length of the connector 96 is selected so that the gap between the tubes 14a and 14b is still bridged when the sliding sleeve engages with its sliding portion 24 in the tube 14a.

Figuren 12 und 13 zeigen eine Variante mit einer zweiteiligen Schiebehülse 22', die einen Schiebeabschnitt 24' und einen davon getrennten Aufnahmeabschnitt 26' aufweist. Der Aufnahmeabschnitt 26' ist auf dem Schiebeabschnitt 24 verschiebbar und über einen Steckverbinder 98 mit dem Rohr 14b verbunden. FIGS. 12 and 13 show a variant with a two-part sliding sleeve 22 ', which has a sliding portion 24' and a separate receiving portion 26 '. The receiving portion 26 'is slidable on the sliding portion 24 and connected via a connector 98 to the tube 14b.

Um den Volumenstromregler 28 zu entnehmen, wird der Aufnahmeabschnitt 26 auf den Schiebeabschnitt 24' geschoben, wie in Fig. 13 gezeigt ist. Das Gehäuse des Volumenstromreglers bleibt dabei an dem Ende des Schiebeabschnitts 24' hängen und tritt so aus dem Aufnahmeabschnitt 26' aus, so dass er durch die entstehende Lücke entnommen werden kann.To remove the volumetric flow controller 28, the receiving portion 26 is pushed onto the sliding portion 24 ', as in Fig. 13 is shown. The housing of the volumetric flow controller remains hanging on the end of the sliding portion 24 'and thus emerges from the receiving portion 26', so that it can be removed through the resulting gap.
