Abstract

The volume flow regulator (1), particularly for air-conditioning installation, involves a throttle component (5) in a channel and pivotable around an axis (4) running crossways to the flow direction (a) of a gas. The throttle component, under the effect of the forwardly flowing gas, is pivoted out of the opening position into the closed position. It is pivoted back again into the opening position under the effect of reducing volume flow. The throttle component is formed by a cylinder cover-shaped vane formed on at least one rotary leg (3), the length of which corresponds approximately to that of the leg. On the rotary leg at least one surface component (8) is provided. The axis of the rotary leg is arranged at a short distance from a wall (2) of the channel.

Description

Die Erfindung betrifft einen Volumenstromregler, insbesondere für klimatechnische Anlagen, mit einem in einem Kanal um eine quer zur Strömungsrichtung eines Gases verlaufende Achse verschwenkbaren Drosselelement, wobei das Drosselelement unter Einwirkung des anströmenden Gases aus der Offenstellung in die Schließstellung verschwenkt wird und bei sich verringerndem Volumenstrom wieder in die Offenstellung zurückschwenkt.The invention relates to a volume flow controller, in particular for air conditioning systems, with one in one duct around a transverse to the direction of flow of a gas Axle pivotable throttle element, the throttle element under the influence of the inflowing gas from the Open position is pivoted into the closed position and with a decreasing volume flow back into the open position swings back.

Derartige Volumenstromregler sind in verschiedenen Ausführungen bekannt. Sie arbeiten mechanisch selbsttätig. Als Drosselelemente können Drosselklappen oder Schiebeelemente vorgesehen sein. Bei einem bekannten Volumenstromregler ist eine Drosselklappe vorgesehen, die um eine quer zur Strömungsrichtung des Gases verlaufende, in der Mitte des Kanals angeordnete Achse verschwenkbar ist. An dem der Achse gegenüberliegenden Ende der Drosselklappe ist ein kreisförmig ausgebildeter Winkel. Dieser Winkel dient zur Abdichtung gegenüber einem bis in die Mitte des Kanals hineinragenden ortsfesten Kanalblech. Such volume flow controllers are available in different versions known. They work mechanically automatically. As Throttle elements can be throttle valves or sliding elements be provided. With a known volume flow controller a throttle valve is provided which is transverse to the Direction of flow of the gas, in the middle of the Channel arranged axis is pivotable. On which the Axle opposite end of the throttle valve is one circular angle. This angle is used for Sealing against one in the middle of the channel protruding stationary duct sheet.

Die Drosselklappe unterteilt den Kanal in Strömungsrichtung derart, dass auf der einen Seite der Drosselklappe ein Stauraum gebildet wird und auf der anderen Seite die Gasauslassöffnung liegt. Bei geringem Druck des anströmenden Gases befindet sich die Drosselklappe mit dem Winkel in dem Stauraum. Sobald die Differenz zwischen dem Gesamtdruck und dem statischen Druck in dem Stauraum größer als der statische Druck in der Gasauslassöffnung ist, wird die Drosselklappe mit dem Winkel in die Gasauslassöffnung verschwenkt, so dass die Strömung reduziert bzw. unterbrochen wird.The throttle valve divides the channel in the direction of flow such that on one side of the throttle valve a storage space is formed and on the other side the Gas outlet opening is. At low pressure the inflowing Gases is the throttle valve with the angle in the storage space. Once the difference between the total pressure and the static pressure in the storage space is greater than is the static pressure in the gas outlet opening, the Throttle valve pivoted into the gas outlet opening at the angle, so that the flow is reduced or interrupted becomes.

Nachteilig ist, dass aufgrund der Anordnung der Drosselklappe in der Offenstellung lediglich ein geringer Durchströmquerschnitt bezogen auf den Kanalquerschnitt in Strömungsrichtung gesehen vor dem Volumenstromregler zur Verfügung steht. Außerdem unterliegen derartige Drosselklappen einem erhöhten Verschleiß, da auf die Drosselklappe selbst ein Drehmoment wirkt.The disadvantage is that due to the arrangement of the throttle valve only a small flow cross-section in the open position related to the channel cross section in Flow direction seen in front of the volume flow controller Available. In addition, such throttle valves are subject increased wear and tear because of the throttle valve even a torque works.

Aufgabe der Erfindung ist es daher, einen Volumenstromregler anzugeben, dessen maximal verfügbarer Austrittsquerschnitt im Bereich des Drosselelementes im Wesentlichen dem Kanalquerschnitt in Strömungsrichtung gesehen vor dem Volumenstromregler entspricht und der darüber hinaus konstruktiv einfach aufgebaut ist.The object of the invention is therefore a volume flow controller specify the maximum available outlet cross section in the area of the throttle element essentially the channel cross-section seen in the flow direction before Volume flow controller corresponds and in addition constructively is simply constructed.

Diese Aufgabe wird dadurch gelöst, dass das Drosselelement aus einem an zumindest einem Drehschenkel angeformten, zylindermantelförmig ausgebildeten Flügel, dessen Radius in etwa der Länge des Drehschenkels entspricht, besteht, wobei an dem Drehschenkel wenigstens ein Flächenelement vorgesehen ist, und dass die Achse des Drehschenkels in geringem Abstand zu einer Wand des Kanals angeordnet ist. In der Offenstellung befindet sich der Flügel in etwa parallel zu einer Wand des Kanals, so dass der maximal zur Verfügung stehende Austrittsquerschnitt im Bereich des Flügels nicht wesentlich kleiner als der Querschnitt des Kanals vor dem Volumenstromregler ist. Der Flügel selbst unterliegt nahezu keinem Verschleiß, da aufgrund der radialen Anordnung des Flügels um die Achse kein Drehmoment auf dem Flügel selbst wirkt. Der Antrieb des Flügels erfolgt durch das(die) Flächenelement(e). Bei niedrigem Druck ist entweder kein oder lediglich ein geringes Verschwenken des Flügels zu verzeichnen, während bei hohem Volumenstrom durch das Auftreffen des anströmenden Gases auf das(die) Flächenelement(e) der Flügel mehr und mehr in die Schließstellung bewegt wird. Jedes Flächenelement kann z. B. als Prallplatte ausgebildet sein.This object is achieved in that the throttle element from a cylinder jacket shaped on at least one rotating leg trained wing, whose radius in corresponds approximately to the length of the rotating leg, where at least one surface element is provided on the rotating leg is, and that the axis of the swivel leg in little Distance to a wall of the channel is arranged. In the wing is approximately parallel to the open position to a wall of the canal so that the maximum is available standing outlet cross-section in the area of the wing not significantly smaller than the cross section of the channel before the volume flow controller. The wing itself is subject to almost no wear, because of the radial Arrangement of the wing around the axis no torque the wing itself. The wing is driven through the surface element (s). At low pressure either no or only a slight pivoting of the Wing to record, while at high volume flow by the impact of the inflowing gas on the Surface element (s) of the wing more and more in the closed position is moved. Each surface element can e.g. B. as Baffle plate be formed.

Die Einstellung eines Sollwertes, bei dem der Volumenstromregler mittels des Flügels die Strömung des Gases unterbricht, kann durch die Anzahl an Flächenelementen bestimmt werden. Bei steigender Anzahl an Flächenelementen wird der zur Verfügung stehende Strömungsquerschnitt im Bereich des Volumenstromreglers verringert, so dass der Flügel, der durch das(die) von dem Gas angeströmten Flächenelement(e) angetrieben wird, die Strömung des Gases schon bei geringen Volumenströmen reduziert bzw. unterbricht.The setting of a setpoint at which the volume flow controller interrupts the gas flow by means of the wing, can by the number of surface elements be determined. With increasing number of surface elements the available flow cross section in the Range of the volume flow controller is reduced so that the Wing which is caused by the surface area (s) flowed by the gas is driven, the flow of gas reduced or interrupted even with low volume flows.

Der/Die Drehschenkel können entweder an der von dem Volumenstrom angeströmten Stirnseite des Flügels oder etwa mittig an dem Flügel angeformt sein.The / the turn leg can either on the volume flow face of the wing or about be integrally formed on the wing.

Damit in der Schließstellung des Flügels ein größerer Bereich des Strömungsquerschnitts des Kanals abgedeckt wird, kann eine Stauleiste vorgesehen sein, die zum Abschluss der Wand des Kanals zum Flügel unter Bildung eines geringen Spaltes entsprechend angeordnet und ausgebildet ist.So that in the closed position of the wing a larger area the flow cross-section of the channel is covered, A storage bar can be provided to complete the wall of the channel to the wing forming a slight Gap is arranged and designed accordingly.

Jedes Flächenelement kann an den Drehschenkeln z. B. angeformt oder angeschraubt sein. Damit aber die Anzahl an Flächenelementen leicht und schnell verändert werden kann, bietet sich an, wenn das(die) Flächenelement(e) mittels einer Clips- bzw. Rastverbindung angebracht ist(sind). Hierdurch ist ein einfaches Lösen und Befestigen der Flächenelemente möglich.Each surface element can z. B. molded or be screwed on. But with that the number of Surface elements can be changed easily and quickly, lends itself when the surface element (s) are created using a clip or snap connection is (are) attached. This makes it easy to loosen and fasten the surface elements possible.

Bei einer anderen Variante der Sollwertverstellung kann in dem Bereich der Wand des Kanals, an dem der Flügel bei vollständiger Schließstellung anliegt, ein Strömungsquerschnittsverringerungselement vorgesehen sein. Durch das Strömungsquerschnittsverringerungselement wird der Strömungsquerschnitt im Bereich des Volumenstromreglers verringert, und der Flügel liegt in der Schließstellung früher an der Wand an.In another variant of the setpoint adjustment, in the area of the wall of the channel where the wing is at completely closed position is present, a flow cross-section reducing element be provided. By the Flow cross section reduction element becomes the flow cross section reduced in the area of the volume flow controller, and the wing is earlier in the closed position on the wall.

Zweckmäßigerweise kann das Strömungsquerschnittsverringerungselement als ein quer zur Strömungsrichtung angeordnetes, insbesondere in der Neigung verstellbares Leitblech ausgebildet sein, wobei die Neigung des Leitbleches vorzugsweise von außerhalb des Kanals verstellbar ist.The flow cross-section reduction element can expediently as a transverse to the direction of flow, especially adjustable baffle be formed, the inclination of the guide plate preferably is adjustable from outside the channel.

Sofern eine Verstellung des Strömungsquerschnittsverringerungselementes nicht gewünscht ist, kann das Strömungsquerschnittsverringerungselement integraler Bestandteil der Wand des Kanals sein. In diesem Fall kann die entsprechende Wand einfach abgeschrägt sein.If an adjustment of the flow cross-section reducing element is not desired, the flow cross section reduction element integral part the wall of the canal. In this case, the corresponding Simply bevel the wall.

Eine andere Möglichkeit der Vorgabe eines Sollwerts besteht darin, dass an dem(den) Drehschenkel(n) vorzugsweise anströmseitig eine Feder angreift. Durch die spezifische Federkraft wird vorgegeben, ab welchem Volumenstrom der Flügel verschwenkt wird. Es ist aber auch durchaus denkbar, dass auf der Abströmseite der Drehschenkel beispielsweise eine Blattfeder vorgesehen ist.Another option is to specify a setpoint in that preferably on the swivel leg (s) a spring engages on the upstream side. By the specific Spring force is specified from which volume flow the Wing is pivoted. But it is also quite conceivable that on the downstream side of the swivel, for example a leaf spring is provided.

Um zu verhindern, dass der Flügel während der Regelung in Schwingungen gerät, kann(können) der(die) Drehschenkel mit einem Dämpfer, insbesondere Schwingungsdämpfer ausgerüstet sein. Die Dämpfung kann entweder durch Reibung erfolgen, wobei beispielsweise zwei Feststoffe durch direkten Kontakt aufeinanderreiben, oder durch hydraulische oder pneumatische Effekte bewirkt werden. Aber auch eine magnetische berührungslose Dämpfung ist möglich. Hierzu ist beispielsweise an dem(den) Drehschenkel(n) ein entsprechend der Verschwenkung ausgelenktes, sich durch ein Magnetfeld eines Magneten bewegendes metallisches Dämpfungselement vorgesehen. Bei Bewegung wird in dem Dämpfungselement ein Strom erzeugt, und ein Magnetfeld in dem Dämpfungselement induziert. Dieses in dem Dämpfungselement induzierte Magnetfeld tritt in Wechselwirkung mit dem Magnetfeld des Magneten, wobei sich beide Magnetfelder nun anziehen, so dass die Schwingungen gedämpft werden.To prevent the wing from turning in during regulation If the device is vibrating, the rotating leg (s) can a damper, especially vibration damper equipped his. The damping can be done either by friction, where, for example, two solids by direct Contact each other, or by hydraulic or pneumatic effects are brought about. But also one magnetic non-contact damping is possible. For this is, for example, a corresponding on the swivel leg (s) the pivoting deflected itself through a Magnetic field of a magnet moving metallic damping element intended. When moving is in the damping element generates a current, and a magnetic field in the Damping element induced. This in the damping element induced magnetic field interacts with the Magnetic field of the magnet, with both magnetic fields now tighten so that the vibrations are dampened.

Fig. 1 zeigt einen Volumenstromregler 1, der, in einer nicht dargestellten klimatechnischen Anlage wie z. B. Klimaanlage eingebaut ist. Der Volumenstromregler 1 besteht aus Wänden 2, die einen Kanal bilden. In dem Volumenstromregler 1 befinden sich zwei Drehschenkel 3, die mit ihrem einen Ende drehbar um eine Achse 4 gelagert sind. Die Achse 4 ist dabei in geringem Abstand zu der in dieser Figur oben dargestellten Wand 2 des Volumenstromreglers 1 angeordnet.Fig. 1 shows a volume flow controller 1, which, in a not shown air conditioning system such. B. Air conditioning is installed. The volume flow controller 1 exists from walls 2 that form a channel. In the volume flow controller 1 there are two swivel legs 3, with their one end are rotatably mounted about an axis 4. The Axis 4 is at a short distance from that in this figure Wall 2 of the volume flow controller 1 shown above arranged.

An dem der Achse 4 gegenüberliegenden Ende der Drehschenkel 3 ist als Drosselelement ein Flügel 5 angeformt, der in etwa zylindermantelförmig geformt ist. In dem in Fig. 1 dargestellten Ausführungsbeispiel sind die Drehschenkel 3 an der der Strömung (a) eines Gases zugewandten Stirnseite des Flügels 5 angeformt. Der Radius des Flügels 5 entspricht in etwa der Länge der Drehschenkel 3.At the end of the rotary leg opposite the axis 4 3, a wing 5 is formed as a throttle element is shaped like a cylinder jacket. In the in Fig. 1st The exemplary embodiment shown are the rotary legs 3 on the front side facing the flow (a) of a gas of the wing 5 molded. The radius of the wing 5 corresponds approximately to the length of the rotating leg 3.

An der in Fig. 1 unten dargestellten Wand 2 des Volumenstromreglers 1 ist auf der der Strömung (a) des Gases abgewandten Seite der Drehschenkel 3 eine Stauleiste 6 angeformt. Die Höhe und Ausrichtung der Stauleiste 6 ist so gewählt, dass zwischen dem Flügel 5 und der Oberkante der Stauleiste 6 während des kompletten Schwenkwegs ein geringer Spalt 7 verbleibt.On the wall 2 of the volume flow controller shown in FIG. 1 below 1 is on the side facing away from the flow (a) of the gas Side of the rotating leg 3, a baffle bar 6 integrally formed. The height and orientation of the storage bar 6 is so chosen that between the wing 5 and the top of the Ram bar 6 a little during the entire swivel path Gap 7 remains.

Wie auch in Fig. 2 deutlich zu erkennen ist, sind zwischen den Drehschenkeln 3 Flächenelemente 8 als Antriebsmittel für den Flügel 5 vorgesehen. Die Strömung (a) des Gases strömt gegen die Flächenelemente 8, so dass die Drehschenkel 3 zusammen mit dem Flügel 5 und den Flächenelementen 8 aus der mit durchgezogenen Linien dargestellte Position in Richtung des Pfeiles 9 in die mit gestrichelten Linien dargestellte Position verschwenkt werden und so die Strömung (a) des Gases entsprechend verringert wird. In der gestrichelt dargestellten Stellung ist die Strömung (a) des Gases bereits teilweise unterbrochen.As can also be clearly seen in FIG. 2, there are between the rotating legs 3 surface elements 8 as drive means provided for the wing 5. The flow (a) of the gas flows against the surface elements 8, so that the rotating leg 3 together with the wing 5 and the surface elements 8 from the position shown in solid lines in Direction of arrow 9 in the dashed lines shown position are pivoted and so the flow (a) the gas is reduced accordingly. In the Position shown in dashed lines is the flow (a) of the gas has already been partially interrupted.

Zur Sollwerteinstellung kann die Anzahl an Flächenelementen 8, die beispielsweise eingeklebt oder eingeschraubt sein können, variiert werden. Es sind aber auch Rast- bzw. Clipsverbindungen denkbar. Je mehr Flächenelemente 8 vorgesehen sind, desto eher schwenkt der Volumenstromregler 1 in die Schließstellung und reduziert die Strömung (a) des Gases.The number of surface elements can be used to set the setpoint 8, for example glued or screwed can be varied. But there are also rest or Clip connections possible. The more surface elements 8 are provided volume flow controller 1 swivels in the closed position and reduces the flow (a) of the Gas.

Bei dem in Fig. 1 dargestellten Ausführungsbeispiel ist ein vollständiges Verschließen durch den Flügel 5 nicht möglich, da der Flügel 5 nur verschwenken kann, solange zwischen dem Flügel 5 und der Wand 2 eine Strömung herrscht. Bei vollständigem Verschließen wäre der Druck auf beiden Seiten der Flächenelemente 8 gleich. In diesem Fall wäre keine Druckdifferenz über die Flächenelemente 8 zum Antrieb des Flügels 5 vorhanden. In the embodiment shown in Fig. 1 a complete closure by the wing 5 is not possible because the wing 5 can only pivot as long a flow between the wing 5 and the wall 2 prevails. If it was closed completely, the pressure would be on both sides of the surface elements 8 the same. In this The case would be no pressure difference across the surface elements 8 to drive the wing 5 available.

Fig. 3 zeigt ein anderes Ausführungsbeispiel, bei dem eine Stauleiste 6 nicht erforderlich ist, da der Flügel 5 gegen die Strömungsrichtung (a) verlängert wurde. Schwenkt der Flügel 5 in die gestrichelt dargestellte Stellung, so bewirkt der auf der Anströmseite der Drehschenkel 3 vorgesehene Bereich des Flügels 5 eine hinreichende Abdichtung gegenüber der in dieser Figur unteren Wand 2.Fig. 3 shows another embodiment in which a Ram bar 6 is not required because the wing 5 against the flow direction (a) has been extended. Pivots the Wing 5 in the position shown in dashed lines, so causes the one provided on the upstream side of the rotating leg 3 Adequate sealing area of the wing 5 opposite the lower wall 2 in this figure.

In Fig. 4 ist in dem Volumenstromregler 1 zusätzlich ein Strömungsquerschnittsverringerungselement 10 vorgesehen, das den Schwenkweg des Flügels 5 in Richtung des Pfeiles 9 begrenzt. In dem dargestellten Ausführungsbeispiel ist das Strömungsquerschnittsverringerungselement 10 als Leitblech 11 ausgebildet, das in der Neigung in Richtung des Pfeils 12 verstellbar ist.In Fig. 4 is in the volume flow controller 1 in addition Flow cross-section reducing element 10 provided, that the swivel path of the wing 5 in the direction of arrow 9 limited. In the illustrated embodiment, this is Flow cross section reduction element 10 as a baffle 11 formed in the inclination in the direction of the arrow 12 is adjustable.

Fig. 5 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Volumenstromreglers 1, bei dem auf der Anströmseite der Drehschenkel 3 eine Feder 13 zur Vorgabe eines Sollwerts vorgesehen ist. Übersteigt die Geschwindigkeit der Strömung (a), die auf die Flächenelemente 8 trifft, die Federkraft der Feder 13, so werden die Drehschenkel 3 mit dem Flügel 5 in Richtung des Pfeils 9 verschwenkt.Fig. 5 shows a further embodiment of an inventive Volume flow controller 1, on the upstream side the rotating leg 3 a spring 13 for default a setpoint is provided.
