- a liquid flow 21 for heating and another liquid flow 22 are provided for cooling.
- a chemical reaction takes place in the reactor 7 and is carried out at a constant temperature and usually at a high temperature.
- warm water and cold water are mixed to provide a suitable temperature through a mixing path 13 and passed to the reactor 7 to ensure this chemical reaction.
- the two liquid circuits 21, 22 are each fed by two cryostats 9, 10, which respectively temper a liquid circuit to a constant temperature.
- the cryostat 9, 10 can only give off its heating or cooling power if the circuit 21, 22 can provide a sufficient flow of water.
- the higher the flow the more powerful a cryostat.
- the more constant a flow the more stable the temperature of a cryostat.
- the RE module 8 At the input and output of the RE module 8, there are two actuators, each based on two valves V1 and V2 or V3 and V4. Through the valves v1 and v2, the RE module 8 takes its share of him supplied hot and cold water to achieve a desired temperature by mixing. The mixed water is passed to the temperature control of the chemical reaction via the mixing path 13 to the reactor 7 and then divided by the valves V3 and V4 and each returned to the circuits 21,22.
- a bypass is formed consisting of a hot bypass B1 and a cold bypass B2. This ensures that the cryostats 9, 10 each experience a constant minimum flow.
- the RE module 8 has a valve V5, V6, which is usually a manual rotary valve.
- V5, V6 can not be controlled automatically depending on a specific proportion ratio in which the hot water and the cold water are mixed. That is, the flow of water to the bypass, for example, can only be controlled manually. That's why the bypasses are B1, B2 not variable.

- V1-V4 By means of valves V1-V4, the supply and the return currents of the tempering water can be controlled.
- the cryostats 9, 10 experience different flows because the total flow rates in the cryostats 9, 10 vary due to the combination of invariable bypass flows and variable tempering currents. Therefore, the cryostats 9,10 are confronted with different water flow rates of their tempering media. As a rule, however, the cryostats 9, 10 should experience as constant a flow as possible in all operating states.
- the bypasses B1, B2 must be tracked during the temperature control so that the total flow rates in the cryostat 9,10 are constant.

Abstract
Description
Die Erfindung betrifft eine Mischvorrichtung zur Mischung von Substanzen, insbesondere Flüssigkeiten oder Gasen mit verschiedenen Temperaturen, mit einer beweglichen, einstellbaren Ventilregelscheibe und mindestens einer fest stehenden Ventilsitzscheibe.The invention relates to a mixing device for mixing substances, in particular liquids or gases with different temperatures, with a movable, adjustable valve control disk and at least one fixed valve seat disk.
Bei einem Mischungssystem wird bspw. ein Mischungsmodul durch zwei getrennte Kreisläufe jeweils für eine zu mischende Substanz versorgt. Das Mischungsmodul entnimmt dadurch für sich seinen Anteil an den verschiedenen, zu mischenden Substanzen, um eine gemischte Substanz mit einem gewünschten Charakter zu ermöglichen. Dabei werden mehre Ventile zur Verteilung und zur Leitung oder Mischung der verschiedenen Substanzen gebraucht. Dies macht das Mischungssystem oder das Mischungsmodul kompliziert und kostenungünstig. Das Mischungssystem ist auf Grund des Einsatzes einer großen Menge von Ventilen nicht praktisch anzusteuern. Darüber hinaus, wird ein Mischungsweg in dem Mischungssystem häufig durch einen oder mehrere Bypässe, worauf jeweils eine zu mischende Substanz geleitet wird, zum Schützen des Mischungsmoduls bzw. zur Kompensation der Kreisläufe überbrückt. Üblicherweise wird der Bypass durch ein extra Handdrehventil geregelt und ist somit nicht variabel.In a mixing system, for example, a mixing module is supplied by two separate circuits each for a substance to be mixed. The mixing module thereby extracts for itself its share of the various substances to be mixed in order to allow a mixed substance with a desired character. Several valves are needed for distribution and for the conduction or mixing of the various substances. This makes the mixing system or the mixing module complicated and costly. The mixing system is not practical to control due to the use of a large amount of valves. In addition, a mixing path in the mixing system is often bridged by one or more bypasses, on each of which a substance to be mixed is passed, to protect the mixing module or to compensate for the cycles. Usually, the bypass is controlled by an extra manual rotary valve and is therefore not variable.
Es wurde auch ein Multiventil entwickelt, wobei zwei Ventile zu einem Ventil zusammengebaut werden. Das Mutiventil ist mit zwei fixen Bohrungen jeweils für einen Bypass versehen. Obwohl die Zahl von gebrauchten Ventilen dadurch eingespart werden kann, ist ein so ausgebildeter Bypass aber ebenfalls invariabel. Wünschenswert sollte ein Mischungssystem einen variablen Bypass aufweisen, wobei der Bypass abhängig von Mischungseinstellungen automatisch anpassbar ist. Je mehr von einer Substanz zur Mischung in einen Mischungsweg des Mischungssystems fließt, desto weniger von der Substanz fließt in einen Bypass, vice versa. Weiterhin fließt von einer Substanz automatisch mehr in den Mischungsweg zur Mischung, wenn von der anderen Substanz oder von den anderen Substanzen weniger in diesen Mischungsweg fließt oder fließen.It has also been developed a multi-valve, with two valves are assembled into a valve. The Mutiventil is provided with two fixed holes each for a bypass. Although the number of used valves can be saved, a bypass formed in this way is also invariable. Desirably, a mixing system should have a variable bypass, whereby the bypass is automatically adjustable depending on mixture settings. The more of a substance flows to the mixture in a mixing path of the mixing system, the less of the substance flows in a bypass, vice versa. Furthermore, more of a substance automatically flows into the mixing path to the mixture when less of the other substance or substances flow or flow into this mixture path.
Der Erfindung liegt die Aufgabe zu Grunde, eine Mischvorrichtung mit Bypassanpassung zur Mischung von Substanzen, insbesondere Flüssigkeiten oder Gasen mit verschiedenen Temperaturen, zu realisieren.The invention is based on the object to realize a mixing device with bypass adaptation for mixing substances, in particular liquids or gases with different temperatures.
Diese Aufgabe wird erfindungsgemäß durch eine Mischvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Die abhängigen Ansprüche betreffen vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung.This object is achieved by a mixing device with the features of
Der Erfindung liegt die Erkenntnis zugrunde, den Strom einer Substanz durch eine Öffnung abhängig von der Querschnittgröße der Öffnung ändern zu können. Daher wird eine Mischvorrichtung zur Mischung von Substanzen, insbesondere Flüssigkeiten oder Gasen mit verschiedenen Temperaturen, mit einer beweglichen, einstellbaren Ventilregelscheibe und mindestens einer fest stehenden Ventilsitzscheibe angegeben, wobei die Ventilsitzscheibe zumindest zwei Öffnungsgruppen, die jeweils aus mindestens drei durchgehenden Öffnungen bestehen, aufweist. Dabei werden eine erste Öffnung als Zulauföffnung oder als Ablauföffnung für eine Substanz, eine zweite Öffnung zur Verbindung mit einem Mischungsweg für die Substanzen und eine dritte Öffnung zur Überbrückung des Mischungswegs vorgesehen. Die Ventilregelscheibe ist zumindest einseitig mit einer ersten Vertiefung und einer zweiten Vertiefung versehen. Durch solche Vertiefungen kann für jede Öffnungsgruppe der Ventilsitzscheibe jeweils ein Durchlass für Substanzen zwischen den Öffnungen - der ersten, der zweiten und der dritten Öffnung - der Ventilsitzscheibe realisiert werden. Die Ventilregelscheibe wird parallel zu der Ventilsitzscheibe so angeordnet, dass bei jeder Öffnungsgruppe über die erste Vertiefung ein Durchfluss zwischen der ersten Öffnung und der zweiten Öffnung und über die zweite Vertiefung ein Durchfluss zwischen der ersten Öffnung und der dritten Öffnung möglich ist. Zur Bildung eines Durchlasses wird z.B. die erste Öffnung jeweils durch die erste und die zweite Vertiefung überlagert. Die Ventilregelscheibe ist zu der Ventilsitzscheibe zur Steuerung der Mischung so einzustellen, dass bei jeder Öffnungsgruppe die gesamten, überlagerten Flächen der ersten Öffnung konstant bleiben. Dazu bleibt die Summe der jeweils durch die ersten Vertiefungen überlagerten Flächen der ersten Öffnungen der gesamten Öffnungsgruppen konstant, und die Summe der jeweils durch die zweiten Vertiefungen überlagerten Flächen der ersten Öffnungen der gesamten Öffnungsgruppen bleibt ebenfalls konstant. Ein variabler Bypass kann bei dieser Mischvorrichtung derart realisiert werden, dass der Durchlass einer Substanz in den Bypass abhängig von ihrem Durchlass in den Mischungsweg geändert wird. Durch Einstellung der Ventilregelscheibe kann man einen Durchlassquerschnitt, nämlich die überlagerte Fläche der ersten Öffnung der Ventilsitzscheibe und der ersten oder der zweiten Vertiefung der Ventilregelscheibe verändern und damit das Anteilverhältnis von zumischenden Substanzen steuern. Dabei kann der Bypass an den Mischungsweg automatisch abhängig von Einstellungen der Ventilregelscheibe angepasst werden. Die Ventilregelscheibe und die Ventilsitzscheibe sind im Regelfall eine Rundscheibe, wobei die Ventilregelscheibe zur Einstellung der Mischvorrichtung gegenüber der Ventilsitzscheibe drehbar ist. Sie können auch in einer anderen Form, z.B. Rechteck, ausgestaltet werden, damit die Ventilregelscheibe gegenüber der Ventilsitzscheibe gezogen und geschoben werden kann.The invention is based on the knowledge to be able to change the flow of a substance through an opening depending on the cross-sectional size of the opening. Therefore, a mixing device for mixing substances, in particular liquids or gases with different temperatures, with a movable, adjustable valve control disc and at least one fixed valve seat disc is specified, wherein the valve seat disc at least two opening groups, each consisting of at least three through openings comprises. In this case, a first opening is provided as an inlet opening or as a discharge opening for a substance, a second opening for connection to a mixing path for the substances and a third opening for bridging the mixing path. The valve control disk is provided at least on one side with a first recess and a second recess. Through such depressions, a passage for substances between the openings - the first, the second and the third opening - of the valve seat disc can be realized for each opening group of the valve seat disc. The valve control disc is arranged parallel to the valve seat disc so that at each opening group via the first recess a flow between the first opening and the second opening and the second recess a flow between the first opening and the third opening is possible. For example, to form a passage, the first opening is superimposed by the first and second recesses. The valve control disk is to be adjusted to the valve seat disk to control the mixture so that with each opening group the total, superimposed areas of the first opening remain constant. For this purpose, the sum of the areas of the first openings of the entire opening groups superimposed in each case by the first depressions remains constant, and the sum of the areas of the first openings of the entire opening groups superposed by the second depressions also remains constant. A variable bypass may be realized in this mixing apparatus so that the passage of a substance into the bypass is changed depending on its passage into the mixing path. By adjusting the valve control disk, it is possible to change a passage cross-section, namely the superimposed area of the first opening of the valve seat disk and the first or the second recess of the valve control disk and thus control the proportion of admixing substances. The bypass can be adapted to the mixing path automatically depending on the settings of the valve control disc. The valve control disk and the valve seat disk are generally a round disk, wherein the valve control disk is rotatable relative to the valve seat disk for adjusting the mixing device. They can also be configured in another form, eg a rectangle, so that the valve control disk can be pulled and pushed in relation to the valve seat disk.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung besteht die Mischvorrichtung aus einer Ventilregelscheibe und zwei Ventilsitzscheiben, wobei die Ventilregelscheibe zwischen den zwei Ventilsitzscheiben parallel angeordnet ist. Die Ventilregelscheibe ist jeweils beiderseitig mit einer ersten Vertiefung und einer zweiten Vertiefung versehen. Bei jeder Öffnungsgruppe der zwei Ventilsitzscheiben ist die erste Vertiefung zur Bildung eines Durchlasses zwischen der ersten Öffnung und der zweiten Öffnung vorgesehen, während die zweite Vertiefung zur Bildung eines Durchlasses zwischen der ersten Öffnung und der dritten Öffnung vorgesehen ist. Je zwei der zweiten Vertiefungen, die jeweils auf den beiden Seiten der Ventilregelscheibe angeordnet sind, werden durch einen Kanal zur Ermöglichung eines Durchflusses zwischen den zwei Ventilsitzscheiben miteinander verbunden. Eine derart ausgestaltete Mischvorrichtung kann alleine in einem Mischungssystem zur Erstellung eines Mischungswegs verwendet werden, anstatt zwei obengenannte Mischvorrichtungen, die jeweils nur eine Ventilsitzscheibe besitzen, zu benutzen.According to an advantageous embodiment of the invention, the mixing device consists of a valve control disk and two valve seat disks, wherein the valve control disk is arranged in parallel between the two valve seat disks. The valve control disk is provided on both sides with a first recess and a second recess. In each opening group of the two valve seat discs, the first recess for forming a passage between the first opening and the second opening is provided, while the second Well is provided for forming a passage between the first opening and the third opening. Each two of the second recesses, each disposed on the two sides of the valve control disc, are interconnected by a passage for facilitating flow between the two valve seat discs. A mixing device configured in this way can be used alone in a mixing system for creating a mixing path, instead of using two mixing devices mentioned above, each of which has only one valve seat disc.
Vorteilhafterweise werden die zwei Ventilsitzscheiben identisch ausgestaltet, und die ersten Vertiefungen und die zweiten Vertiefungen können auf den beiden Seiten der Ventilregelscheibe symmetrisch angeordnet werden. Damit kann die Mischvorrichtung in einer einfachsten Weise aufgebaut und geregelt werden.Advantageously, the two valve seat discs are made identical, and the first depressions and the second depressions can be arranged symmetrically on the two sides of the valve control disc. Thus, the mixing device can be constructed and controlled in a simple manner.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist die Mischvorrichtung zumindest zwei Absperrstellungen auf. Wird die Mischvorrichtung in eine der Absperrstellungen eingestellt, kann die Mischung der Substanzen beendet bzw. vermieden werden, d.h. die Substanzen fließen nicht mehr in den Mischungsweg, sondern fließen jeweils vollständig in die Bypässe. Da mindest zwei Absperreinstellungen bei der Mischvorrichtung vorhanden sind, braucht man die Mischvorrichtung nicht unbedingt in einen bestimmten Zustand einzustellen, um die Mischung von den Substanzen zu trennen. Er kann die Mischung schnell bzw. einfach trennen, indem er die Mischvorrichtung in einen Zustand, der einer der Absperrstellungen dieser Mischvorrichtung entspricht, einstellt.According to an advantageous embodiment of the invention, the mixing device has at least two shut-off positions. If the mixing device is set in one of the shut-off positions, the mixture of substances can be stopped or avoided, i. The substances no longer flow into the mixing path, but in each case flow completely into the bypasses. Since there are at least two shut-off positions in the mixing device, it is not necessary to set the mixing device to a specific state in order to separate the mixture from the substances. He can quickly or simply disconnect the mixture by setting the mixing device in a state corresponding to one of the shut-off positions of this mixing device.
In einem Mischungssystem können zwei Mischvorrichtungen, die jeweils nur eine Ventilsitzscheibe besitzen zur Erstellung eines Mischungswegs so eingesetzt werden, dass eine erste Mischvorrichtung als Eingang (Vorlaufventil) und eine zweite Mischvorrichtung als Ausgang (Rücklaufventil) vorgesehen werden, wobei die zweiten Öffnungen der ersten Mischvorrichtung jeweils als Zulauföffnung und die zweiten Öffnungen der zweiten Mischvorrichtung jeweils als Ablauföffnung für eine Substanz angeschlossen werden. Die dritten Öffnungen der ersten Mischvorrichtung werden jeweils mit den entsprechenden dritten Öffnungen der zweiten Mischvorrichtung zur Überbrückung des Mischungswegs verbunden. Dadurch kann man mittels der zwei Mischvorrichtungen ein Mischungsweg und seinen Bypass realisieren. Das Mischungssystem kann somit kostengünstig aufgebaut werden, da hier nur zwei Mischvorrichtungen/Ventile verwendet werden. Die zu mischenden Substanzen werden von den zweiten Öffnungen des Vorlaufventils aus in den Mischungsweg geleitet und darauf miteinander gemischt. Die gemischten Substanzen werden über die zweiten Öffnungen der Ventilsitzscheibe und mit Hilfe der ersten Vertiefungen der Ventilregelscheibe durch die ersten Öffnungen der Ventilsitzscheibe des Rücklaufventils abgeführt. Die durch die ersten Öffnungen des Vorlaufsventils zugeführten, aber nicht zur Mischung geleiteten Substanzen werden jeweils mit Hilfe der zweiten Vertiefungen von den dritten Öffnungen des Vorlaufsventils aus über den Bypass in die dritten Öffnungen des Rücklaufsventils geleitet und dann über die zweiten Vertiefungen der Ventilregelscheibe durch die ersten Öffnungen des Rücklaufventils zur Überbrückung des Mischungswegs weitergeleitet.In a mixing system, two mixing devices, each having only one valve seat disc, can be used to create a mixing path providing a first mixing device as an input (feed valve) and a second mixing device as an output (return valve), the second openings of the first mixing device each as an inlet opening and the second openings of the second mixing device are each connected as a drain opening for a substance. The third openings of the first mixing device are respectively connected to the corresponding third openings of the second mixing device for bridging the mixing path. As a result, one can realize a mixing path and its bypass by means of the two mixing devices. The mixing system can thus be constructed inexpensively, since only two mixing devices / valves are used here. The substances to be mixed are passed from the second openings of the flow valve in the mixing path and mixed with each other. The mixed substances are discharged via the second openings of the valve seat disc and with the aid of the first recesses of the valve control disc through the first openings of the valve seat disc of the return valve. The supplied through the first openings of the flow valve, but not passed to the mixture substances are respectively passed by means of the second wells from the third openings of the flow valve via the bypass into the third openings of the return valve and then through the second recesses of the valve control disk through the first Openings of the return valve for bridging the mixing path forwarded.
Als Alternative kann eine Mischungsvorrichtung, welche eine Ventilregelscheibe und zwei Ventilsitzscheiben besitzt, in das oben genannte Mischungssystem zur Erstellung eines Mischungswegs eingesetzt werden. Dabei wird die Mischvorrichtung zur Erstellung eines Mischungswegs so geschaltet, dass die erste Ventilsitzscheibe als Eingang (Vorlaufscheibe) und die zweite Ventilsitzscheibe als Ausgang (Rücklaufscheibe) des Mischungswegs vorgesehen werden. Die ersten Öffnungen und die dritten Öffnungen der Vorlaufscheibe werden jeweils als Zulaufsöffnung für eine Substanz angeschlossen. Die zweiten Öffnungen der Vorlaufscheibe werden jeweils für eine Substanz als Zulauföffnung des Mischungswegs vorgesehen, während die zweiten Öffnungen der Rücklaufscheibe jeweils für eine gemischte Substanz als Ablauföffnung vorgesehen werden. Die ersten Öffnungen und die dritten Öffnungen der Rücklaufscheibe dienen sich jeweils auch als Ablaufsöffnung. Der Mischungsweg wird überbrückt, indem die zu mischenden Substanzen jeweils den dritten Öffnungen der Vorlaufscheibe zugeführt und dann über zwei zweite Vertiefungen, die sich gegeneinander auf den beiden Seiten der Ventilregelscheibe befinden und durch einen Kanal verbunden sind, durch die ersten und/oder die dritten Öffnungen der Rücklaufscheibe geleitet werden. Dadurch können ein Mischungsweg und ein oder mehrere Bypässe mittels einer einzelnen Mischvorrichtung ermöglicht werden, ohne dass noch ein anderes Ventil gebraucht wird.Alternatively, a mixing device having a valve control disk and two valve seat disks may be inserted into the above-mentioned mixing system for establishing a mixing path. In this case, the mixing device is switched to create a mixing path so that the first valve seat disc as input (Vorlaufscheibe) and the second valve seat disc as the output (return plate) of the mixing path are provided. The first openings and the third openings of the flow disk are each connected as a feed opening for a substance. The second openings of the flow disk are each provided for a substance as an inlet opening of the mixing path, while the second openings of the return plate are each provided for a mixed substance as a drain opening. The first openings and the third openings of the return plate are each also used as a drain opening. The mixing path is bridged by supplying the substances to be mixed in each case to the third openings of the advance disk and then through the first and / or the third openings via two second depressions, which are located opposite one another on the two sides of the valve control disk and are connected by a channel the return plate are passed. Thereby, a mixing path and one or more bypasses by means of a single mixing device can be made possible without the need for another valve.

Am Eingang und Ausgang des RE-Moduls 8 gibt es zwei Stellglieder, die jeweils auf zwei Ventilen V1 und V2 bzw. V3 und V4 basieren. Über die Ventile v1 und v2 entnimmt das RE-Modul 8 für sich seinen Anteil von ihm zugeführten Warm- und Kaltwasser, um durch eine Mischung eine gewünschte Temperatur zu erreichen. Das gemischte Wasser wird zum Temperieren der chemischen Reaktion über den Mischungsweg 13 an den Reaktor 7 geführt und danach durch die Ventile V3 und V4 aufgeteilt und jeweils wieder in die Kreisläufe 21,22 zurückgeführt.At the input and output of the
Für den Mischungsweg 13 wird eine Überbrückung bestehend aus einem Warm-Bypass B1 und einem Kalt-Bypass B2 ausgebildet. Dies stellt sicher, dass die Kryostaten 9,10 jeweils einen konstanten Mindestdurchfluss erfahren. Für jeden Bypass weist das RE-Modul 8 ein Ventil V5,V6 auf, welches in der Regel ein Handdrehventil ist. Solche Ventile können jedoch nicht je nach einem bestimmten Anteilverhältnis, in dem das Warmwasser und das Kaltwasser gemischt werden, automatisch geregelt werden. D.h., der Durchfluss von Wasser auf den Bypass kann bspw. nur manuell gesteuert werden. Deswegen sind die Bypässe B1,B2 nicht variabel. Auch wenn die Ventile V5,V6 jeweils mit den Stellgliedern V1,V2 und V3,V4 zusammen als ein Multiventil ausgebildet werden, werden die Ventile V5,V6 aber bisher nur einmalig in Form von zwei fixen Bohrungen realisiert. Obwohl in diesem Fall die Zahl von gebrauchten Ventilen eingespart werden kann, ist ein so ausgebildeter Bypass jedoch immer noch invariabel.For the mixing

Darüber hinaus, bedarf dieses Mikroreaktionssystem wegen mehrerer Ventile ebenfalls einer hohen Anzahl an Schrittmotoren. Damit verbunden ist die Gefahr des Auseinanderdriftens der Ventilstellungen zueinander wegen Schrittverlusten der Schrittmotoren. Die Anzahl der Ventile und Schrittmotoren verursachen zusätzlich einen hohen Platzbedarf und höhere Kosten.In addition, because of several valves, this microreaction system also requires a large number of stepper motors. This is associated with the risk of divergence of the valve positions to each other due to step losses of the stepper motors. The number of valves and stepper motors also require a lot of space and higher costs.
Die Ventilsitzscheibe 2 weist zwei Öffnungsgruppen 11,12 auf, die jeweils für Steuerung und Durchlass von Warmwasser und Kaltwasser vorgesehen sind. Dabei umfasst jede Öffnungsgruppe eine erste Öffnung w1,k1, eine zweite Öffnung ma,mb zur Erstellung eines Mischungswegs 13 und eine dritte Öffnung w2,k2 zur Überbrückung des Mischungswegs.

Aus dieser Tabelle ist zu erkennen, dass bei Einstellung der Ventilregelscheibe 1 die gesamten Wasserströme des in den Mischungsweg 13 und in den Bypass B1 fließenden Warmwassers oder die gesamten Wasserströme des in den Mischungsweg 13 und in den Bypass B2 fließenden Kaltwassers immer konstant bleiben, weil die gesamten, überlagerten Flächen der ersten Öffnung w1,k1 der Ventilsitzscheibe 2, die jeweils die erste Vertiefung wn1,kn1 und die zweite Vertiefung wn2,kn2 überlappen, konstant bleiben. Die überlagerten Flächen der ersten Öffnung w1,k1 können jeweils als ein Durchlassquerschnitt für Warmwasser und Kaltwasser angesehen werden. Die Größe des Durchlassquerschnittes ist als Zulaufsöffnung für Wasser einzustellen, damit das Warmwasser und das Kaltwasser mit einem geeigneten Anteil gemischt werden können. Zum Beispiel, je mehr das Warmwasser durch den gesamten Querschnitt, also die überlagerte Fläche, der ersten Vertiefung wn1 und der ersten Öffnung w1 in den Mischungsweg 13 fließt, desto weniger fließt das Warmwasser durch den gesamten Querschnitt der zweiten Vertiefung wn2 und der ersten Öffnung w1 in den Bypass B1.From this table it can be seen that when adjusting the
Außerdem bleibt die Summe der Fläche, die den gesamten Querschnitt der ersten Vertiefung wn1 und der ersten Öffnung w1 und den gesamten Querschnitt der ersten Vertiefung kn1 und der ersten Öffnung k1 umfasst, ebenfalls konstant. Deshalb kann automatisch und gleichzeitig z.B. mehr Warmwasser durch die zweite Öffnung ma zur Mischung in den Mischungsweg 13 fließen, wenn der Kaltwasserstrom durch die andere zweite Öffnung mb kleiner eingestellt wird. Das gleiche gilt auch für das Warmwasser und das Kaltwasser in den Bypassstrecken B1 und B2.In addition, the sum of the area including the entire cross section of the first recess wn1 and the first opening w1 and the entire cross section of the first recess kn1 and the first opening k1 also remains constant. Therefore can automatically and at the same time, for example, more hot water through the second opening ma to the mixture flow into the mixing

Die Kombination von zwei solchen Mischvorrichtungen in Verbindung mit der Temperieraufgabe im Mikroreaktionssystem lässt die Vorteile einer solchen Mischvorrichtung deutlich werden. Mit diesen Mischvorrichtungen ist es möglich zwei getrennte Wasserkreisläufe zu mischen und im gleichen Verhältnis wieder aufzuteilen.The combination of two such mixing devices in connection with the tempering task in the microreaction system reveals the advantages of such a mixing device. With these mixing devices, it is possible to mix two separate water circuits and to divide them in the same ratio again.
