Description

VORRICHTUNG ZUM REGELN DER STRÖMUNG VON GASFÖRMIGEN UND FLÜSSIGEN MEDIEN, INSBESONDERE LUFTDEVICE FOR REGULATING THE FLOW OF GASEOUS AND LIQUID MEDIA, IN PARTICULAR AIR
Die Erfindung betrifft eine Vorrichtung zum Regeln der Strömung von gasförmigen und flüssigen Medien, insbesondere Luft, die ein Gehäuse, quer zum Strömungsweg des Mediums ange¬ ordnete und im geschlossenen Zustand den Innenquerschnitt des Gehäuses abdeckende bewegbare Sperrelemeπte sowie eine sich den Sperrelementen aπschliessende Betätigungseinrichtung aufweist. Die bekannten zum Regeln der Strömung von gasförmigen und flüssigen Medien, insbesondere Luft dienenden Vorrichtungen weisen bandförmige Sperrelemente auf, die an der einen Seite ihrer Länge drehbar gelagert sind. Beim Schliessen der regelba¬ ren Vorrichtung liegen die einzelnen Sperrelemente auf dem benachbarten Sperrelement auf und sperren den Strömuπgsweg des Mediums. In geöffnetem Zustand sind die einzelnen Sperrelemente sich voneinander entfernend in Richtung der Strömung des Me¬ diums einstellbar. Die Sperrelemeπte derartiger Strömungsrege- lungsvorrichtuπgen sind kinematisch miteinander verbunden und befinden sich zueinander während der Bewegung im wesentlichen in planparalleler Lage, die Betätigungseinrichtung verursacht ein gemeinsames Verdrehen der Sperrelemente . Hinsichtlich ihrer Ausbildung kann die Betätigungseinrichtung als manuelle Einrichtung oder mittels eines Zugmagneteπ , eines Elektromo- tors, eines Arbeitszylinders oder einer sonstigen geeigneten Einrichtung realisiert werden. Derartige Strömungsreglervor- richtuπgen sind im Handel , ihr Aufbau ist in dem "Müszaki Le¬ xikon" (Akademiai Kiadό, Budapest, 1984) (Lexikon der Technik),The invention relates to a device for regulating the flow of gaseous and liquid media, in particular air, which has a housing, movable locking elements which are arranged transversely to the flow path of the medium and, in the closed state, cover the inner cross section of the housing, and an actuating device which closes the locking elements. The known devices for regulating the flow of gaseous and liquid media, in particular air, have band-shaped blocking elements which are rotatably mounted on one side of their length. When the controllable device is closed, the individual blocking elements rest on the adjacent blocking element and block the flow path of the medium. In the open state, the individual blocking elements can be set apart from one another in the direction of the flow of the medium. The blocking elements of such flow control devices are kinematically connected to one another and are essentially plane-parallel to one another during the movement; the actuating device causes the blocking elements to rotate together. With regard to its design, the actuating device can be implemented as a manual device or by means of a pull magnet, an electric motor, a working cylinder or another suitable device.

Diese bekannte Lösung hat den Nachteil, dass für die Betätigung der Strömungsreglervorrichtung eine gesonderte Ein¬ richtung auszubilden ist, die auch gesteuert werden muss. Dies ist einerseits kostenaufwendig und beeaπsprucht andererseits gesonderte Energie. Als weiterer Mangel wäre noch zu erwähnen, dass ihre Absperrfähigkeit unvollkommen ist und somit diese Vorrichtungen für eine sichere Absperrung nicht geeignet sind.This known solution has the disadvantage that a separate device has to be designed for the actuation of the flow regulator device, which device must also be controlled. On the one hand, this is expensive and, on the other hand, it requires separate energy. Another deficiency should be mentioned that their locking ability is imperfect and therefore these devices are not suitable for secure locking.

Das bewegbare Gitter 14 ist mit einer in Achseπrichtuπg wirkenden Betätiguπgseinrichtung 11 verbunden.The invention relates to a device for regulating the flow of gaseous and liquid media, in particular air, which is described in more detail below with reference to the medium-regulating flow regulator devices illustrated in the drawing. FIG. 1 shows a manually operated variant of the flow control device according to the invention, which is illustrated in the upper part of the figure in the closed state and in the lower part of the figure in the open state. The flow control device has a housing 1, movable locking elements 4 arranged transversely to the flow path of the medium and in the closed position covering the inner cross section of the housing 1, and an actuating device 11 connected to the movable locking elements 4. The flow regulator device is further provided with fixed blocking elements 5 cooperating with the movable blocking elements 4, which form a fixed grid 15 having concentric rings, which is reinforced with webs in the direction of the diameter. The movable locking elements 4 are designed as concentric rings and together form an axially displaced Slidable webs 13 arranged in the direction of the diameter, reinforced movable grille 14. In a pressed position, the annular blocking elements 4, 5 of the fixed grille 15 and of the movable grille 14 lie against one another, blocking off the flow path of the medium, as can be seen from the upper half of FIG. 1 can be seen. The movable grating 14 is connected to an actuating device 11 acting in the axis direction.
Die Betätigungseinrichtung 11 ist mit einer Zugvorπch- tung 1B und einer Kette 16 versehen, die mit einer mittels einer Feder 6 in Sperrichtuπg vorgespannten Achse 19 verbunden ist. An der Achse 19 schliesst sich über ihr Schraubengewinde 20 eine das bewegbare Gitter 14 tragende Nabe 2 an. Das beweg¬ bare Gitter 14 ist in dem Gehäuse 1 in Achseπrichtuπg ver- schiebbar geführt und mittels einer an dem Gehäuse 1 befestig¬ ten Führungsπase 12 gegen Verdrehung gesichert. Das von der Na¬ be 2 weiter entfernte Ende der Achse 19 ist in einem die Feder 6 aufnehmenden Gehäuse 17 ebenfalls in Achsenrichtung verschiebbar geführt, wobei das Gehäuse 17 mittels Halterippen 10 an dem Mantel des Gehäuses 1 abgestützt ist.The actuating device 11 is provided with a pulling device 1B and a chain 16 which is connected to an axle 19 which is biased in the locking direction by means of a spring 6. On the axis 19 is connected via its screw thread 20 a hub 2 carrying the movable grating 14. The movable grille 14 is guided in the housing 1 so as to be displaceable in the axial direction and is secured against rotation by means of a guide lug 12 fastened to the housing 1. The end of the axle 19 which is farther from the hub 2 is also guided in a housing 17 which accommodates the spring 6 and is displaceable in the axial direction, the housing 17 being supported on the casing of the housing 1 by means of retaining ribs 10.
Die in Figur 1 veranschaulichte Ausführuπgsform der er¬ findungsgemässen Strömungsreglervorrichtung funktioniert folgenderweise:The embodiment of the flow control device according to the invention illustrated in FIG. 1 functions as follows:
In der in dem oberen Teil der Figur veraπschaulich- teπ geschlossenen Position wird das bewegbare Gitter 14 von der Nabe 2 und über die Achse 19 von der Feder 6 gegen das festste¬ hende Gitter 15 gedrückt, während die bewegbaren und festste¬ henden Sperrelemente 4,5 aneinander anliegend den Weg der Luft¬ strömung absperren. Mit Hilfe der Zugvorrichtuπg 18 und über die Kette 16 ist die Achse 19 gegen die Feder 6 in Achsenrich¬ tung in die der unteren Hälfte der Figur entsprechende Posi¬ tion verschiebbar. Dabei entfernen sich die bewegbaren Sperrelemente 4 des bewegbaren Gitters 14 von den feststehenden Sperrelementen 5 des feststehenden Gitters 15, wodurch der Weg der Luftströmung über die Öffnungen zwischen den Sperrelementen 4,5 frei wird. Es ist erkennbar, dass eine kleine axiale Bewe¬ gung einen relativ grosseπ Strömuπgsquersschnitt freisetzt. In dem Weg des strömenden Mediums verbleiben zwar sowohl das be¬ wegbare Gitter 14 als auch das feststehende Gitter 15, der da- durch verursachte Luftwiderstand kann jedoch durch entsprechen¬ de Ausbildung des Querschnittes der Sperrelemente 4,5 auf ei¬ nen kleinen Wert gehalten werden. In geschlossener Position schliesseπ sich die kegelartigen Flächen der Sperrelemente 4,5 fest zusammen, wodurch eine wirkvolle Absperrung realisiert werden kann.In the closed position shown in the upper part of the figure, the movable grille 14 is pressed against the fixed grille 15 by the hub 2 and via the axis 19 by the spring 6, while the movable and fixed locking elements 4, 5 adjacent to each other, block the path of the air flow. With the aid of the pulling device 18 and via the chain 16, the axis 19 can be displaced against the spring 6 in the axial direction into the position corresponding to the lower half of the figure. The movable locking elements 4 of the movable grille 14 move away from the fixed locking elements 5 of the fixed grille 15, which clears the way for the air flow through the openings between the locking elements 4, 5. It can be seen that a small axial movement releases a relatively large flow cross section. Both the movable grille 14 and the fixed grille 15, which However, air resistance caused by appropriate design of the cross section of the locking elements 4, 5 can be kept at a small value. In the closed position, the cone-like surfaces of the locking elements 4, 5 firmly close together, which means that an effective shut-off can be realized.
Da die Nabe 2 über das Schraubengewinde 20 an der Achse 19 befestigt ist, wird das Verdrehen , das während der Funktion ein Lockerwerdeπ verursacht, von einer aus der inneren Mantel- flache des Gehäuses 1 nach innen ragenden Nase 12 verhindert, welche mit einer entsprechenden in Richtung der Erzeugenden ausgebildeten Nut des sich an dem die Sperrelemente 4 tragenden Steges 13 aπschliesseπden Mantels im Eingriff steht.Since the hub 2 is fastened to the axle 19 by means of the screw thread 20, the twisting, which causes a loosening during operation, is prevented by a nose 12 protruding inwards from the inner surface of the housing 1, which protrudes with a corresponding in Direction of the generating groove formed in the mantle on the web 13 carrying the locking elements 4 is connected.
Natürlich kann anstelle der manuellen Lösung in dem Gehäuse 17 auch ein Zugmagnet eingebaut sein.Of course, a pull magnet can also be installed in the housing 17 instead of the manual solution.
Figur 2 zeigt eine mittels eines Motors betätigte Variante der erfindungsgemässen Strömungsreglervorrichtung, die in der oberen Hälfte der Figur im geschlossenen und in der unteren Hälfte der Figur im geöffneten Zustand dargestellt ist. Der Unterschied zu der in Figur 1 veranschaulichten Ausführuπgsform besteht darin, dass die Achse 19 an einer elektrischen Rotationsmaschine 7 angeschlossen ist, oder gleichzeitig auch deren Achse. Das Schraubengewinde 20 und die Rotationsmaschine 7 bilden gemeinsam die Betätigungseinrichtung 11. Die gemäss Figur 2 ausgebildete Ausführungsform der er¬ findungsgemässen Strömungsreglervorrichtung funktioniert wie folgt:FIG. 2 shows a variant of the flow control device according to the invention actuated by means of a motor, which is shown in the upper half of the figure in the closed state and in the lower half of the figure in the open state. The difference from the embodiment shown in FIG. 1 is that the axis 19 is connected to an electric rotary machine 7, or at the same time the axis thereof. The screw thread 20 and the rotary machine 7 together form the actuating device 11. The embodiment of the flow control device according to the invention, which is designed according to FIG. 2, functions as follows:
Die Rotationsmaschine 7 dreht die Achse 19, die in Abhängigkeit von der Drehrichtung über das Schraubengewinde 20 die Nabe 2 und das daran befestigte bewegbare Gitter 14 inThe rotary machine 7 rotates the axis 19 which, depending on the direction of rotation via the screw thread 20, the hub 2 and the movable grating 14 attached to it
Achsenrichtung bewegt, da sich das letztere nicht drehen kann. In Abhängigkeit von dem Anstieg des Schraubengewindes 20 kann eine äusserst grosse axial gerichtete Kraft ausgeübt werden, das ein sicheres Abschliessen ermöglicht. Um zu grosse Kraftwirkungen zu vermeiden, ist es zweckmässig, dafür irgendeine Lösung, zum Beispiel einen in dem Stromkreis der Rotationsmaschine 7 -eingefügten auf Krafteinwirkung ansprechenden Trennschalter zu ver¬ wenden.Axis direction moves because the latter can not turn. Depending on the increase in the screw thread 20, an extremely large axially directed force can be exerted, which enables secure locking. In order to avoid excessive force effects, it is expedient to use some solution for this, for example a disconnector which responds to the action of force and is inserted in the circuit of the rotary machine 7.
Figur 3 zeigt eine von der mit einem in Achsenrichtung verschiebbaren Rotor 9 versehenen elektrischen Rotatioπs aschi- ne betätigte Ausführungsform der erfindungsgemässen Strömungs¬ reglervorrichtung, die mit einem axialen Ventilator kombiniert ist. In dem oberen Teil der Figur ist die Rotaatioπsmaschiπe 7 im Ruhezustand und in dem unteren Teil der Figur im Betriebszu- stand dargestellt. Das Besondere dieser Kombination besteht darin, dass das bewegbare Gitter 14 mit dem Schaufelrad 3 zusammengebaut ist, wobei die Sperrelemente 4 in dem bewegbaren Gitter 14 von den Schaufeln des Schaufelrades 3 in konzentri- scher Lage gehalten werden. Das Schaufelrad 3 und das bewegbare Gitter 14 sind einer gemeinsamen Nabe 2 zugeordnet, die an der Achse der elektrischen Rotationsmaschiπe 7 befestigt ist. Die Betätigungseiπrichtung 11 hat folgenden Aufbau: Der Rotor 9 der Rotatioπsmaschine 7 ist in Achseπrichtung verschiebbar und die in Ruhelage zwischen der Rotationsmaschine 7 und der Nabe 2 angeordnete Feder 6 zieht den Rotor 9 bis zu 10-40 % seiner Länge aus dem Stator 8 heraus. Die Federkraft der Feder 6 hält das bewegbare Gitter 14 und das feststehende Gitter 15 in zusammengeschlossener Lage. Die in Figur 3 veranschaulichte Ausführungsform der erfindungsgemässen Strömungsreglervorrichtung funktioniert folgenderweise:Figure 3 shows one of those with one in the axial direction Slidable rotor 9 provided with electrical rotary actuated embodiment of the flow control device according to the invention, which is combined with an axial fan. In the upper part of the figure the rotary machine 7 is shown in the idle state and in the lower part of the figure in the operating state. The special feature of this combination is that the movable grille 14 is assembled with the paddle wheel 3, the locking elements 4 in the movable grille 14 being held in a concentric position by the blades of the paddle wheel 3. The paddle wheel 3 and the movable grating 14 are assigned to a common hub 2, which is attached to the axis of the electrical rotary machine 7. The actuating device 11 has the following structure: The rotor 9 of the rotary machine 7 can be displaced in the axial direction and the spring 6 arranged in the rest position between the rotary machine 7 and the hub 2 pulls the rotor 9 up to 10-40% of its length out of the stator 8. The spring force of the spring 6 holds the movable grille 14 and the fixed grille 15 in a closed position. The embodiment of the flow control device according to the invention illustrated in FIG. 3 functions as follows:
Beim Einschalten funktioniert die Rotationsmaschine 7 als Zugmagπet, der das an der Nabe 2 befestigte bewegbare Gitter 14 gegen die Feder 6 in Öffπungsrichtung bewegt. Dabei entfernen sich die Sperrelemeπte 4,5 voneinander und die Rotatioπsmaschine beginnt sich zu drehen und dreht dabei auch das Schaufelrad 3 und das daran befestigte bewegbare Gitter 14. Infolge der Spannwirkung der Feder 6 kann der Rotor 9 der Rotationsmaschine 7 niemals die in magnetischer Hinsicht optimale Position einnehmen, da die Feder 6 ihn aus dieser - wenn auch in geringem Masse - herauslenkt. Aus diesem Grunde verringert sich in gewissem Masse der Wirkungsgrad der Rota¬ tionsmaschiπe 7. Dies kann zumindest teilweise durch die auf das Schaufelrad 3 wirkende aerodynamische Kraft kompensiert werden, wenn die Richtung der Luftströmung mit der des hohlem Pfeiles in der Figur übereinstimmt. Beim Abstellen drückt dieWhen switched on, the rotary machine 7 functions as a pull magnet which moves the movable grating 14 fastened to the hub 2 against the spring 6 in the opening direction. The locking elements 4, 5 move away from each other and the rotary machine begins to rotate and also rotates the paddle wheel 3 and the movable grating 14 attached to it. As a result of the tensioning action of the spring 6, the rotor 9 of the rotary machine 7 can never be the magnetically optimal one Take up position, because the spring 6 directs him out of this - albeit to a small extent. For this reason, the efficiency of the rotary machine 7 is reduced to a certain extent. This can be at least partially compensated for by the aerodynamic force acting on the paddle wheel 3 if the direction of the air flow corresponds to that of the hollow arrow in the figure. When parking, presses
Feder 6 äusserst schnell die bewegbaren Sperrelemente 4 an die feststehenden Sperrelemente 5 und diese bremsen durch gegenseitige Reibung die Vorrichtung. Auf Wirkung der Bremsrei¬ bung schleifen sich die Sperrelemente 4,5 aneinander an, wodurch sich ihre Luftabsperrfähigkeit weiter erhöht. Es ist zweckmässig, wenn das Material der Sperrelemente 4 härter ist, weil sich in diesem Falle das leichter austauschbare feststehende Gitter 15 schneller abnutzt.Spring 6 extremely quickly the movable locking elements 4 to the fixed locking elements 5 and these brake mutual friction the device. As a result of the brake friction, the locking elements 4, 5 rub against one another, which further increases their air shut-off capability. It is expedient if the material of the locking elements 4 is harder, because in this case the more easily exchangeable fixed grid 15 wears out faster.
Figur 4 zeigt eine mit einem schraubenförmigen Riegel und einem Riegelnut-Paar öffnende Variante der erfindungsgemässen Strömungsreglervorrichtung in Kombination mit einem Radialveπtilator im geschlossenen Zustand, während Figur 6 die gleiche Strömungsreglervorrichtung im geöffneten Zustand veranschaulicht. Diese Ausführuπgsform unterscheidet sich von der vorangehenden einerseits in der für den Fachmann wohlbekannten Ausbildung des Schaufelrades 3 und andererseits in der Lösung der Betätigungseinrichtung 11. Auf der Achse 19 der Rotationsmaschiπe 7 ist eine schraubenförmige Riegelbahn 22 ausgebildet, in welcher ein Riegel 21, der in die Nabe 2 des auf die Achse 19 aufgezogenen Schaufelrades 3 eingepasst ist, verschiebbar angeordnet ist. Das Schaufelrad 3, oder genauer genommen das an dem Schaufelrad 3 befestigte bewegbare Gitter 14 wird von der Feder 6 in die geschlossene Position gezwungen.FIG. 4 shows a variant of the flow regulator device according to the invention opening with a helical bolt and a pair of bolt grooves in combination with a radial ventilator in the closed state, while FIG. 6 illustrates the same flow regulator device in the open state. This embodiment differs from the previous one on the one hand in the design of the paddle wheel 3, which is well known to the person skilled in the art, and on the other hand in the solution of the actuating device 11. On the axis 19 of the rotary machine 7, a helical bolt track 22 is formed, in which a bolt 21 which is inserted into the Hub 2 of the impeller 3 mounted on the axle 19 is fitted, is arranged displaceably. The paddle wheel 3, or more precisely the movable grille 14 attached to the paddle wheel 3, is forced into the closed position by the spring 6.
Die in den Figuren 4 und 6 veranschaulichte erfindungs- gemässe Strömungsreglervorrichtu; funktioniert folgenderweise:The flow regulator device illustrated in FIGS. 4 and 6; works as follows:
Im Ruhezustand kann sich das an das feststehende Gitter 15 angedrückte bewegbare Gitter 14 infolge der zwischen ihnen auftretenden Reibung nicht verdrehen. Deshalb bewegt bei ' Anlassen der Rotationsmaschine 7 die sich auf der sich drehen¬ den Achse 19 befindliche Riegelbahn 22 über den Riegel 21 die Nabe 2 in Richtung der Rotationsmaschine 7 sowie das daran aπ- geschlossene Schaufelrad 3 und das bewegbare Gitter 14 gegen die Feder 6. Nach dem Aufheben der Reibung bewegt sich der Riegel 21 infolge der Bremswirkung der Luft und der Trägheit weiter entlang der Riegelbahn 22, d.h. dass sich der Vorgang des Öffneπs fortsetzt. Beim Abstellen zwingt die Feder 6 die Strömungsreglervorrichtung in den geschlossenen Zustand zurück. Die Steilheit des Anstieges der Riegelbahn 22, die Charakteri¬ stik der Feder 6 sind im Zusammenhang mit der durch die Luft auf das Schaufelrad 3 ausgeübten Bremskraft zu bestimmen.In the idle state, the movable grille 14 pressed against the fixed grille 15 cannot rotate due to the friction occurring between them. Therefore, in 'starting move the rotary machine 7 on which drehen¬ the axis 19 of latch track located 22 via the bolt 21, the hub 2 in the direction of the rotary machine 7 and the aπ- it closed impeller 3 and the movable mesh 14 against the spring 6 After the friction has been removed, the bolt 21 moves further along the bolt path 22 due to the braking effect of the air and the inertia, ie the process of opening continues. When switched off, the spring 6 forces the flow regulator device back into the closed state. The steepness of the rise of the locking track 22, the characteristics of the spring 6 are to be determined in connection with the braking force exerted on the impeller 3 by the air.
Figur 5 zeigt eine mögliche Variante der Anpassung der Sperrelemeπte 4,5 in vergrössertem Massstab. Die im geschlosse¬ nen Zustand auf die Strömungsreglervorrichtung wirkende Druckdifferenz wirkt in grösserem Mass auf dasjenige Sperrele- meπt 4 oder 5 ein, dessen Wirkfläche in der zur Achsenrichtung senkrechten Ebene grösser ist, d.h. dessen Neigung bzw. Konizität grösser ist. Es ist zweckmässig, diesen Umstand bei dem Öffnen und Schliessen und bei der Bestimmung der Richtung der Luftströmung zu berücksichtigen.Figure 5 shows a possible variant of the adaptation of the Locking elements 4.5 on an enlarged scale. The pressure difference which acts on the flow regulator device in the closed state acts to a greater extent on the blocking element 4 or 5, the effective surface of which is larger in the plane perpendicular to the axis direction, ie its inclination or taper is greater. It is advisable to take this into account when opening and closing and when determining the direction of the air flow.
Figur 7 zeigt eine der in Figur 4 veranschaulichten ähn- liehe Ausführuπgsform der erfindungsgemässen Strömungsregler¬ vorrichtung, die mit einer elektrischen Rotationsmaschine mit in Achseπrichtuπg verschiebbarem Rotor kombiniert ist. In dem oberen Teil der Figur steht die Rotatioπsmaschine 7, die Strö¬ mungsreglervorrichtung ist geschlossen, während in dem unteren Teil der Figur die Rotationsmaschine 7 läuft und die Strömungs¬ reglervorrichtung im geöffneten Zustand ist. Die Funktion stimmt im wesentlichen mit der Funktion der in Figur 3 veran¬ schaulichten Ausführungsform überein. FIG. 7 shows a similar embodiment of the flow regulator device according to the invention illustrated in FIG. 4, which is combined with an electric rotary machine with a rotor which can be displaced in the axis. In the upper part of the figure is the rotary machine 7, the flow control device is closed, while in the lower part of the figure the rotary machine 7 is running and the flow control device is in the open state. The function essentially corresponds to the function of the embodiment illustrated in FIG. 3.
