Description

Die Erfindung betrifft einen mechanisch selbsttätig arbeitenden Volumenstromregler, insbesondere für raumlufttechnische, von einem Medium durchströmte Anlagen, mit einem eine Wandung aufweisenden, einen Teil eines Strömungskanals bildenden Gehäuse, mit einer im Inneren des Gehäuses auf einer quer zur Strömungsrichtung angeordneten Welle schwenkbar gelagerten Klappe, wobei die Klappe unter Einwirkung des die Klappe anströmenden Mediums gegen eine Rückstellkraft aus einer Offenstellung in eine Schließstellung verschwenkbar ist und bei sich verringerndem Volumenstrom des strömenden Mediums durch die Rückstellkraft wieder in die Offenstellung zurückschwenkt.The invention relates to a mechanically self-acting volumetric flow controller, in particular for raumlufttechnische, flowed through by a medium systems, having a wall having a part of a flow channel forming housing, with a inside the housing on a transversely arranged to the flow wave wave flap, wherein the flap under the action of the fluid flowing against the flap against a restoring force from an open position into a closed position is pivotable and pivots back at the decreasing volume flow of the flowing medium by the restoring force back to the open position.

Die Klappe kann drehfest an der Welle befestigt sein, so dass sich dann die Welle gegenüber dem Gehäuse dreht. Die Welle kann dabei einseitig oder beidseitig gegenüber dem Gehäuse gelagert sein. Auch können anstelle einer durchgehenden Welle in zwei gegenüberliegenden Bereichen der Klappe je einen seitlich über die Außenkontur der Klappe vorstehenden Wellenstummel vorgesehen sein. Alternativ kann die Welle drehfest an dem Gehäuse angeordnet sein. In diesem Fall dreht sich dann die Klappe um die Welle. Dabei kann nur eine Ende oder beide Enden der Welle an dem Gehäuse befestigt sein. Anstelle einer durchgehenden Welle kann das Gehäuse in zwei gegenüberliegenden Bereichen je einen nach innen weisenden Wellenstummel aufweisen. Bei mechanisch selbsttätig arbeitenden Volumenstromreglern wird die Klappe unter Einwirkung des die Klappe anströmenden Mediums gegen eine Rückstellkraft aus einer Offenstellung in eine Schließstellung verschwenkt. Verringert sich das Druckgefälle vor und hinter der Klappe, wird die Klappe durch die Rückstellkraft wieder in ihre Offenstellung zurückgeschwenkt. Derartige Volumenstromregler arbeiten mechanisch selbsttätig, weil das strömungsbedingte Regelklappendrehmoment durch die Rückstellkraft, die üblicherweise durch eine Feder erzeugt wird, kompensiert wird. Nachteilig bei bekannten Volumenstromreglern ist, dass die Stellung der Klappe von außen nicht sichtbar ist. Daher ist nicht in jedem Fall ein energieoptimierter Arbeitspunkt einstellbar, da - sofern die Klappe beispielsweise nahezu ihre Schließstellung erreicht hat, was von außen nicht sichtbar ist - hohe Druckverluste die Folge sind. Aus der GB 2468292 A ist eine Drosseleinrichtung bekannt, die eine schwenkbar in einem Gehäuse gelagerte Absperrklappe umfasst.The flap may be rotationally fixed to the shaft, so that then rotates the shaft relative to the housing. The shaft can be mounted on one side or on both sides relative to the housing. Also, instead of a continuous shaft in two opposite areas of the flap may each be provided laterally over the outer contour of the flap projecting stub shaft. Alternatively, the shaft may be rotatably mounted on the housing. In this case, then the flap rotates around the shaft. In this case, only one end or both ends of the shaft on the housing be attached. Instead of a continuous shaft, the housing may each have an inwardly facing stub shaft in two opposite areas. In mechanically self-acting volume flow controllers, the flap is pivoted under the action of the material flowing against the flap against a restoring force from an open position to a closed position. If the pressure drop in front of and behind the flap decreases, the flap is returned to its open position by the restoring force. Such volumetric flow controllers work mechanically automatically, because the flow-related control valve torque is compensated by the restoring force, which is usually generated by a spring. A disadvantage of known volumetric flow controllers is that the position of the flap is not visible from the outside. Therefore, not always an energy-optimized operating point is adjustable because - if the flap has almost reached its closed position, for example, which is not visible from the outside - high pressure losses are the result. From the GB 2468292 A a throttle device is known which comprises a pivotally mounted in a housing butterfly valve.

Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und einen Volumenstromregler anzugeben, bei dem auch die Klappenstellung von außerhalb des Gehäuses ohne eine Demontage bestimmbar ist.The object of the invention is to avoid the aforementioned disadvantages and to provide a volumetric flow regulator in which the flap position can be determined from outside the housing without disassembly.

Diese Aufgabe wird dadurch gelöst, dass innerhalb und/oder außerhalb des Gehäuses ein mit der Klappe und/oder mit der Welle mittelbar oder unmittelbar verbundenes und sich entsprechend der Bewegung der Klappe ebenfalls bewegendes Anzeigeelement vorgesehen ist, welches zur Sichtkontrolle der Stellung der Klappe von außerhalb des Gehäuses frei sichtbar angeordnet ist. Aufgrund der erfindungsgemäßen Ausgestaltung kann die Stellung der Klappe jederzeit von außerhalb des Gehäuses bestimmt werden. Da selbsttätig mechanisch arbeitende Regler üblicherweise eine von außen zugängliche Sollwerteinstellung aufweisen, kann der Sollwert bei gleichzeitiger Beobachtung der Klappenstellung optimal eingestellt werden. Hierdurch ist eine energieoptimierte Einregulierung des Arbeitspunktes möglich.This object is achieved in that inside and / or outside of the housing with the flap and / or with the shaft directly or indirectly connected and according to the movement of the flap also moving display element is provided which for visual inspection of the position of the flap from outside of the housing free is arranged visible. Due to the inventive design, the position of the flap can be determined at any time from outside the housing. Since automatically mechanical Working regulators usually have an externally accessible setpoint adjustment, the setpoint can be optimally adjusted while monitoring the flap position. As a result, an energy-optimized adjustment of the operating point is possible.

Zumindest ein Ende der Welle selbst kann als Anzeigeelement ausgebildet sein. So kann das Anzeigeelement eine aufgemalte Kennzeichnung oder eine Einkerbung darstellen. Denkbar ist beispielsweise auch ein Strich, der parallel zur Klappe ausgerichtet ist.At least one end of the shaft itself may be formed as a display element. Thus, the display element may represent a painted marking or a notch. It is also conceivable, for example, a line which is aligned parallel to the flap.

Das Anzeigeelement kann alternativ auch als separates Bauteil ausgebildet sein.The display element may alternatively be formed as a separate component.

Bei einem Ausführungsbeispiel, bei der das Anzeigeelement als separates Bauteil ausgebildet ist, kann das Anzeigeelement an einem Ende der Welle befestigt sein. Hierbei kann es sich beispielsweise um eine auf das Ende der Welle aufgesteckte Scheibe handeln, die eine entsprechende Markierung aufweist.In an embodiment in which the display element is formed as a separate component, the display element may be attached to one end of the shaft. This may for example be a plugged onto the end of the shaft disc having a corresponding mark.

Das Anzeigeelement kann innerhalb des Gehäuses angeordnet sein, und das Gehäuse kann zumindest in dem Bereich des sich entsprechend der Bewegung der Klappe bewegenden Anzeigeelementes aus einem durchsichtigen Material bestehen oder eine, insbesondere mit einem Sichtfenster verschlossene, Ausnehmung aufweisen. Das Gehäuse kann beispielsweise in dem in Rede stehenden Bereich ein durchsichtiges Sichtfenster aufweisen, das so groß ausgebildet ist, dass in jeder Stellung der Klappe das Anzeigeelement sichtbar und damit die Klappenstellung bestimmbar ist. Auch ist eine Ausnehmung in der Wandung des Gehäuses denkbar, die eine Beobachtung des fluchtenden, im Inneren des Gehäuses angeordneten Ende der Welle ermöglicht.The display element can be arranged within the housing, and the housing can, at least in the region of the display element moving according to the movement of the flap, consist of a transparent material or have a recess, in particular closed with a viewing window. For example, in the area in question, the housing may have a transparent viewing window which is designed so large that the display element is visible in every position of the flap and thus the flap position can be determined. Also, a recess in the wall of the housing is conceivable, the an observation of the aligned, arranged in the interior of the housing end of the shaft allows.

Das Gehäuse kann zumindest eine Ausnehmung als Lagerung für ein Ende der Welle aufweisen.The housing may have at least one recess as a bearing for one end of the shaft.

Es bietet sich an, wenn das Ende der Welle außenseitig aus der Ausnehmung hervorsteht. Bei einer solchen Ausgestaltung kann das Anzeigeelement an dem außenseitig aus der Ausnehmung hervorstehenden Ende der Welle befestigt sein. Alternativ kann das außenseitig aus der Ausnehmung hervorstehende Ende der Welle selbst als Anzeigeelement ausgebildet sein.It is advisable if the end of the shaft protrudes from the recess on the outside. In such an embodiment, the display element may be attached to the outside of the recess projecting end of the shaft. Alternatively, the outside of the recess protruding end of the shaft itself may be formed as a display element.

Auf der Außenseite des Gehäuses ist zumindest ein Teil einer Einrichtung zur Erzeugung der Rückstellkraft, insbesondere die ganze Einrichtung zur Erzeugung der Rückstellkraft, angeordnet. Ein Beispiel einer Einrichtung zur Erzeugung der Rückstellkraft zeichnet sich dadurch aus, dass die Welle einen Hebelarm aufweist, an dem gelenkig eine Feder angreift, wobei die Feder beispielsweise eine Blattfeder sein kann, deren eines Ende mit dem Hebel verbunden ist und deren anderes Ende so an einer Kurvenscheibe befestigt ist, dass bei Verstellung der Kurvenscheibe um einen Drehpunkt die Blattfeder von der Kurvenscheibe mitgenommen wird und auf der Kurve abrollt, und dass eine Einrichtung zum Fixieren der Kurvenscheibe vorgesehen ist. Zur Verbindung des Hebels mit dem zugeordneten Ende der Blattfeder kann eine Verbindungsstange oder ein Verbindungsseil vorgesehen sein.On the outside of the housing, at least part of a device for generating the restoring force, in particular the entire device for generating the restoring force, is arranged. An example of a device for generating the restoring force is characterized in that the shaft has a lever arm, on which hingedly engages a spring, wherein the spring may be, for example, a leaf spring, one end of which is connected to the lever and the other end to a cam is fixed, that upon adjustment of the cam about a pivot point, the leaf spring is taken from the cam and rolls on the curve, and that means for fixing the cam is provided. For connecting the lever to the associated end of the leaf spring, a connecting rod or a connecting cable may be provided.

Auf der Außenseite des Gehäuses kann zumindest ein Teil einer Fixiereinrichtung zur Fixierung der Einrichtung zur Erzeugung der Rückstellkraft, insbesondere die ganze Fixiereinrichtung zur Fixierung der Einrichtung zur Erzeugung der Rückstellkraft, angeordnet sein. Sofern die Einrichtung zur Erzeugung der Rückstellkraft eine Kurvenscheibe zur Sollwerteinstellung aufweist, kann die Fixiereinrichtung beispielsweise als Schraube ausgebildet sein, die nach dem Lösen ein Verdrehen der Kurvenscheibe ermöglicht.On the outside of the housing, at least part of a fixing device for fixing the device for generating the restoring force, in particular the entire fixing device for fixing the device for generating the restoring force, be arranged. If the device for generating the restoring force has a cam for setpoint adjustment, the fixing device may be formed, for example, as a screw, which enables after loosening a rotation of the cam.

Das Gehäuse weist eine außenseitige Abdeckung auf, die zumindest einen Teilbereich des außerhalb des Gehäuses angeordneten Teils der Fixiereinrichtung außenseitig in Richtung der Längserstreckung der Welle abdeckt und/oder die zumindest einen Teilbereich des außerhalb des Gehäuses angeordneten Teils der Einrichtung zur Erzeugung der Rückstellkraft außenseitig in Richtung der Längserstreckung der Welle abdeckt und/oder die zumindest einen Teilbereich des außerhalb des Gehäuses angeordneten Teils des Anzeigeelementes außenseitig in Richtung der Längserstreckung der Welle abdeckt, wobei entweder die Abdeckung zumindest in dem Bereich des sich entsprechend der Bewegung der Klappe ebenfalls bewegenden Anzeigeelementes aus einem durchsichtigen Material besteht oder eine, insbesondere mit einem Sichtfenster verschlossene, Ausnehmung aufweist oder das Anzeigeelement außerhalb der Abdeckung liegt. Bei einem außerhalb der Abdeckung angeordneten Anzeigeelement kann das Anzeigeelement beispielsweise als Scheibe bzw. als Scheibensegment ausgebildet sein, dass beispielsweise seitlich gegenüber der Abdeckung hervorsteht und so ein Ablesen ermöglicht.The housing has an outside cover which covers at least a portion of the part of the fixing device arranged outside the housing on the outside in the direction of the longitudinal extension of the shaft and / or the outside at least a portion of the outside of the housing part of the device for generating the restoring force in the direction of the outside covering the longitudinal extent of the shaft and / or covers the at least a portion of the arranged outside the housing part of the display element on the outside in the direction of the longitudinal extent of the shaft, wherein either the cover at least in the region of the corresponding movement of the flap also moving display element of a transparent Material consists or one, in particular closed with a viewing window, recess or the display element is outside the cover. In a display element arranged outside the cover, the display element may be formed, for example, as a disk or as a disk segment that, for example, laterally protrudes from the cover and thus allows reading.

Die Abdeckung kann aus einem Blech bestehen. Selbstverständlich sind auch andere Materialien denkbar. Auch die Ausgestaltung aus einem Lochblech, aus einem Gitter, aus einem durchsichtigen Material oder dergleichen ist möglich.The cover may consist of a sheet metal. Of course, other materials are conceivable. The design of a perforated plate, from a grid, from a transparent material or the like is possible.

Die Abdeckung kann einen, vorzugsweise umlaufenden, in Richtung des Gehäuses abgewinkelten Kragen aufweisen. Dann ist der von der Abdeckung verdeckte Bereich auch von der Seite nicht einsehbar.The cover may have a, preferably circumferential, angled in the direction of the housing collar. Then the area covered by the cover is not visible from the side.

So kann der Volumenstromregler rund ausgebildet sein und mittels geeigneter Aufschiebemuffen mit den nicht dargestellten Luftkanälen verbunden sein.In the figures, a mechanically self-acting volume flow controller is shown in angular design. This has a, having a wall and a part of a flow channel forming housing 1. At each of the two free ends of the housing 1, a flange 2 is formed. By means of the flanges 2, the volumetric flow controller can be connected to air ducts, not shown. Other cross sections of the volumetric flow controller are also conceivable. Thus, the volumetric flow controller may be round and connected by means of suitable Aufschiebemuffen with the air ducts, not shown.

Im Inneren des Gehäuses 1 ist auf einer quer zur Strömungsrichtung 3 angeordneten Welle 4 eine Klappe 5 schwenkbar gelagert. Die Klappe 5 ist drehfest an der Welle 4 befestigt. Die Klappe 5 ist unter Einwirkung eines die Klappe 5 anströmenden Mediums gegen eine Rückstellkraft aus ihrer Offenstellung, sowie sie beispielsweise in Fig. 3 dargestellt ist, in ihre Schließstellung verschwenkbar. Bei sich verringerndem Volumenstrom des strömenden Mediums wird die Klappe 5 durch die Rückstellkraft wieder in ihre Offenstellung zurückgeschwenkt.Inside the housing 1, a flap 5 is pivotally mounted on a shaft 4 arranged transversely to the flow direction 3. The flap 5 is rotatably attached to the shaft 4. The flap 5 is under the action of a flowing the flap 5 medium against a restoring force from its open position, and they, for example, in Fig. 3 is shown, pivotable in its closed position. With decreasing volume flow of the flowing medium, the flap 5 is pivoted back by the restoring force in its open position.

In dem dargestellten Ausführungsbeispiel ist in zwei gegenüberliegenden Wandungen je eine Ausnehmung 6 vorgesehen, durch die das jeweilige Ende 7 der Welle 4 nach außen hindurchgeführt ist. Die Ausnehmungen 6 dienen insoweit als Lagerung für die Welle 4. Die Welle 4 ist im Bereich der beiden Ausnehmungen 6 durch nicht dargestellte Abdichtungen gegenüber dem Gehäuse 1 abgedichtet.In the illustrated embodiment, a respective recess 6 is provided in two opposite walls, through which the respective end 7 of the shaft 4 is passed to the outside. The recesses 6 serve insofar as storage for the shaft 4. The shaft 4 is sealed in the region of the two recesses 6 by seals, not shown, relative to the housing 1.

Wie insbesondere in den Figuren 2 und 3 dargestellt ist, ist außenseitig auf eines der beiden Enden 7 der Welle 4 ein Anzeigeelement 8 in Form eines separat ausgebildeten Bauteils aufgesteckt. Dieses Anzeigeelement 8 weist eine Markierung in Form eines Striches auf. Der Strich ist parallel zur Stellung der Klappe 5 ausgerichtet. Das Anzeigeelement 8 dreht sich bei Veränderung der Stellung der Klappe 5 mit.As in particular in the Figures 2 and 3 is shown, on the outside of one of the two ends 7 of the shaft 4, a display element 8 plugged in the form of a separately formed component. This display element 8 has a marking in the form of a line. The stroke is aligned parallel to the position of the flap 5. The display element 8 rotates when changing the position of the flap 5 with.

Wie den Figuren 2 bis 4 zu entnehmen ist, ist auf der Seite des Gehäuses 1, auf der das Anzeigeelement 8 angeordnet ist, eine Abdeckung 9 vorgesehen. Diese Abdeckung 9 besteht in dem dargestellten Ausführungsbeispiel aus einem flächigen Element mit zwei gegenüberliegenden, orthogonal zur Strömungsrichtung 3 ausgerichteten kurzen Kanten 10 und mit zwei gegenüberliegenden, parallel zur Strömungsrichtung 3 ausgerichteten langen Kanten 11.Like that FIGS. 2 to 4 can be seen, a cover 9 is provided on the side of the housing 1, on which the display element 8 is arranged. This cover 9 consists in the illustrated embodiment of a planar element with two opposite, aligned orthogonal to the flow direction 3 short edges 10 and two opposite, parallel to the flow direction 3 aligned long edges 11th

Jeder der beiden kurzen Kanten 10 berührt den jeweils benachbarten Flansch 2 und kann in nicht näher dargestellter Weise an diesem Flansch 2 befestigt sein. Im Bereich der beiden gegenüberliegenden langen Kanten 11 ist die Abdeckung 9 unter Bildung eines Kragens 19 in Richtung des Gehäuses 1 abgewinkelt. Die beiden abgewinkelten Kragen 19 berühren die Wandung des Gehäuses 1. Damit ist der von der Abdeckung 9 abgedeckte Bereich zu allen vier Seiten seitlich verschlossen ausgebildet. Die Abdeckung 9 kann beispielsweise auf das Gehäuse 1 und/oder auf die Flansche 2 aufgesteckt, aufgeklippst oder angeschraubt sein.Each of the two short edges 10 touches the respectively adjacent flange 2 and can be secured in a manner not shown on this flange 2. In the region of the two opposite long edges 11, the cover 9 is angled in the direction of the housing 1 to form a collar 19. The two angled collar 19 touch the wall of the housing 1. Thus, the area covered by the cover 9 is formed laterally closed to all four sides. The cover 9 may for example be plugged, clipped or screwed onto the housing 1 and / or on the flanges 2.

Im Bereich des sich entsprechend der Bewegung der Klappe 5 ebenfalls bewegenden Anzeigeelementes 8 besteht die Abdeckung 9 aus einem durchsichtigen Material. So kann die Abdeckung 9 in diesem Bereich ein Sichtfenster 12 aufweisen. Damit ist das Anzeigeelement 8 trotz montierter Abdeckung 9 sichtbar, so dass die Stellung der Klappe 5 von außerhalb des Gehäuses 1, d.h. von außen durch das Sichtfenster 12, auch im montierten Zustand des Volumenstromreglers erkennbar.In the area of the display element 8, which likewise moves according to the movement of the flap 5, the cover 9 consists of a transparent material. Thus, the cover 9 may have a viewing window 12 in this area. Thus, the display element 8 is visible despite mounted cover 9, so that the position of the flap 5 from outside the housing 1, ie recognizable from the outside through the viewing window 12, even in the assembled state of the volumetric flow controller.

In den Figuren 1 und 4 ist näher die Einrichtung zur Erzeugung der Rückstellkraft dargestellt. Am Gehäuse 1 ist um einen Drehpunkt 13 verschwenkbar eine Kurvenscheibe 14 gelagert, die mit einer nicht dargestellten Fixiereinrichtung zur Fixierung der Einrichtung zur Erzeugung der Rückstellkraft in unterschiedlichen Schwenkstellungen festgelegt werden kann. An dem in Figur 4 oberen Ende einer von der Kurvenscheibe 14 gebildeten Kurve 15 ist eine Feder 16 befestigt, die als Blattfeder ausgebildet ist. Das andere Ende der Feder 16 ist mittels einer Verbindungsstange 17 mit einer Lochscheibe 18 verbunden, die auf der Schwenkwelle 4 der Klappe 5 sitzt.In the FIGS. 1 and 4 closer to the device for generating the restoring force is shown. On the housing 1 is pivotally mounted about a pivot point 13, a cam 14 which can be fixed with a fixing device, not shown, for fixing the device for generating the restoring force in different pivot positions. At the in FIG. 4 upper end of a cam 15 formed by the cam 15, a spring 16 is fixed, which is designed as a leaf spring. The other end of the spring 16 is connected by means of a connecting rod 17 with a perforated disc 18 which sits on the pivot shaft 4 of the flap 5.

In Figur 5 ist die entspannte Feder 16 wiedergegeben. Beim Verschwenken rollt die Feder 16 auf der Kurve 15 der Kurvenscheibe 14 ab, wobei ihr an die Verbindungsstange 17 angeschlossenes Ende eine Durchbiegung erfährt. Sollen die Eigenschaften des Volumenstromreglers verändert werden, dann genügt es, die Kurvenscheibe 14 zu lösen und in eine andere Position zu verstellen.In FIG. 5 is the relaxed spring 16 reproduced. When pivoting, the spring 16 rolls on the curve 15 of the cam 14, wherein its connected to the connecting rod 17 end experiences a deflection. If the properties of the volumetric flow controller are to be changed, then it is sufficient to release the cam plate 14 and move it to another position.

Wie den Figuren zu entnehmen ist, befindet sich die Einrichtung zur Erzeugung der Rückstellkraft außerhalb des Gehäuses 1. Allerdings ist die Einrichtung zur Erzeugung der Rückstellkraft hinter der Abdeckung 9 geschützt angeordnet. Selbstverständlich kann auch die nicht näher dargestellte Fixiereinrichtung zur Fixierung der Einrichtung zur Erzeugung der Rückstellkraft außerhalb des Gehäuses 1 hinter der Abdeckung 9 geschützt angeordnet sein.As can be seen from the figures, the device for generating the restoring force outside the housing 1. However, the means for generating the restoring force behind the cover 9 is arranged protected. Of course, the fixing device, not shown for fixing the device for generating the restoring force outside the housing 1 behind the cover 9 may be arranged protected.

Wie Fig. 1 zu entnehmen ist, ragt der Drehpunkt 13 außenseitig aus dem Gehäuse 1 und auch aus der Abdeckung 9 hervor. Zur Veränderung der Stellung der Kurve 15 kann an dem Drehpunkt 13 beispielsweise ein Handhebel vorgesehen sein. Selbstverständlich ist auch ein Antrieb denkbar, der mit dem Drehpunkt 13 zusammenwirkt.As Fig. 1 can be seen, the pivot point 13 protrudes on the outside from the housing 1 and also from the cover 9. To change the position of the curve 15 may be provided at the pivot point 13, for example, a hand lever. Of course, a drive is conceivable, which cooperates with the pivot point 13.

Es ist selbstverständlich auch möglich, dass beispielsweise die Abdeckung 9 im Bereich der beiden langen Kanten 11 offen ausgebildet ist, so dass in diesen Bereichen die hinter der Abdeckung 9 befindlichen Bauteile von den beiden Seiten erkennbar sind.It is of course also possible that, for example, the cover 9 is designed to be open in the region of the two long edges 11, so that in these areas the components located behind the cover 9 can be seen from the two sides.
