Description

Stand der TechnikState of the art

Es ist bereits eine Gasventilvorrichtung vorgeschlagen worden, welche eine erste Ventileinheit und eine zweite Ventileinheit aufweist, die in einem Betriebszustand gemeinsam eine Fluidleitung öffnen oder schließen. Die erste Ventileinheit und die zweite Ventileinheit sind in einem montierten Zustand durch ein Verbindungselement der Gasventilvorrichtung magnetisch aneinander gekoppelt. Die Gasventilvorrichtung weist zudem eine Spule auf, welche an der ersten Ventileinheit angeordnet ist. Eine Ansteuereinheit versorgt in einem Betriebszustand die Spule zu einer Ansteuerung der Ventileinheiten. In dem Betriebszustand versorgt die Ansteuereinheit die Spule mit einer elektrischen Spannung, welche von Null verschieden ist. Bei angelegter Spannung sind die Ventileinheiten beide geöffnet, wodurch ein Fluid durch die Fluidleitung strömen kann. Um die Fluidleitung zu schließen, trennt die Ansteuereinheit die Spule von der elektrischen Spannung. Die Ansteuereinheit versorgt die Spule demnach lediglich mit einer einzigen von Null verschiedenen elektrischen Spannung.A gas valve device has already been proposed, which has a first valve unit and a second valve unit, which together open or close a fluid line in an operating state. In an assembled state, the first valve unit and the second valve unit are magnetically coupled to one another by a connecting element of the gas valve device. The gas valve device also has a coil which is arranged on the first valve unit. In an operating state, a control unit supplies the coil for controlling the valve units. In the operating state, the control unit supplies the coil with an electrical voltage which is different from zero. When the voltage is applied, the valve units are both open, whereby a fluid can flow through the fluid line. In order to close the fluid line, the control unit disconnects the coil from the electrical voltage. The control unit accordingly only supplies the coil with a single non-zero electrical voltage.

Erfindungsgemäß ist bei angelegter zweiter elektrischer Spannung die erste Ventileinheit geöffnet und die zweite Ventileinheit geschlossen. Dadurch kann die zweite Ventileinheit insbesondere auf eine Funktionsfähigkeit hin überprüft werden. Insbesondere kann überprüft werden, beispielsweise mittels einer Sensoreinheit, ob in Fluidströmungsrichtung betrachtet der zweiten Ventileinheit nachgeschaltet, Fluid vorhanden ist.According to the invention, when the second electrical voltage is applied, the first valve unit is opened and the second valve unit is closed. As a result, the second valve unit can in particular be checked for functionality. In particular, it can be checked, for example by means of a sensor unit, whether fluid is present downstream of the second valve unit when viewed in the direction of fluid flow.

Erfindungsgemäß weist die Gasventilvorrichtung eine Sensoreinheit auf, die dazu vorgesehen ist, zumindest eine Sensorkenngröße hinsichtlich einer Anwesenheit von Fluid in wenigstens einem Abschnitt der Fluidleitung zu detektieren. Insbesondere ist der Abschnitt der Fluidleitung, in welchem die Sensoreinheit in wenigstens einem Betriebszustand insbesondere die Sensorkenngröße hinsichtlich einer Anwesenheit von Fluid detektiert, in Fluidströmungsrichtung betrachtet den Ventileinheiten, insbesondere der ersten Ventileinheit und der zweiten Ventileinheit, nachgeschaltet angeordnet. Unter einer "Sensoreinheit" soll insbesondere eine Einheit verstanden werden, welche zumindest einen Detektor zu einer Detektion der Sensorkenngröße aufweist und welche dazu vorgesehen ist, einen die Sensorkenngröße kennzeichnenden Wert auszugeben, wobei es sich bei der Sensorkenngröße vorteilhaft um eine physikalische und/oder chemische Größe handelt. Dadurch kann insbesondere eine gezielte Fehlersuche ermöglicht werden. Insbesondere kann durch separate Ansteuerung der Ventileinheiten ein Schließzustand zumindest einer der Ventileinheiten durch Detektion von Fluid mittels der Sensoreinheit überprüft werden.According to the invention, the gas valve device has a sensor unit which is provided to detect at least one sensor parameter with regard to the presence of fluid in at least a section of the fluid line. In particular, the section of the fluid line in which the sensor unit detects in particular the sensor parameter with respect to the presence of fluid in at least one operating state is arranged downstream of the valve units, in particular the first valve unit and the second valve unit, when viewed in the direction of fluid flow. A “sensor unit” is to be understood in particular as a unit which has at least one detector for detecting the sensor parameter and which is provided for outputting a value which characterizes the sensor parameter, the sensor parameter advantageously being a physical and / or chemical parameter. In particular, this enables targeted troubleshooting. In particular, by separately actuating the valve units, a closed state of at least one of the valve units can be checked by detecting fluid using the sensor unit.

Erfindungsgemäß ist die Ansteuereinheit dazu vorgesehen, mittels der Sensorkenngröße zumindest einen Schließzustand der zweiten Ventileinheit zu überprüfen. Die Ansteuereinheit ist insbesondere dazu vorgesehen, die Spule über eine insbesondere vorbestimmte Zeitdauer mit der zweiten elektrischen Spannung zu versorgen. Beispielsweise könnte die insbesondere vorbestimmte Zeitdauer einen Wert in einem Bereich von 4 s bis 7 s annehmen. Insbesondere ist die Ansteuereinheit dazu vorgesehen, bei genügendem Schließzustand der zweiten Ventileinheit im Anschluss an die insbesondere vorbestimmte Zeitdauer die Spule mit einer dritten elektrischen Spannung zu versorgen, welche insbesondere von Null verschieden sein und/oder einen Wert von wenigstens im Wesentlichen Null aufweisen könnte. Die dritte elektrische Spannung ist insbesondere von der ersten elektrischen Spannung und von der zweiten elektrischen Spannung verschieden und weist insbesondere einen Wert auf, welcher insbesondere wesentlich kleiner ist als ein Wert der ersten elektrischen Spannung und als ein Wert der zweiten elektrischen Spannung. Die Ansteuereinheit ist insbesondere dazu vorgesehen, bei ungenügendem Schließzustand der zweiten Ventileinheit im Anschluss an die insbesondere vorbestimmte Zeitdauer zumindest eine Warnung auszugeben und/oder einen Betrieb eines die Gasventilvorrichtung aufweisenden Heizsystems zu unterbinden. Hierdurch kann ein Bediener insbesondere vor einem vollständigen Defekt der zweiten Ventileinheit über eine Fehlfunktion informiert werden, wodurch die zweite Ventileinheit insbesondere ausgetauscht und/oder ein verlässlicherer Betrieb eines die Gasventilvorrichtung aufweisenden Heizsystems ermöglicht werden kann. Beispielsweise könnte die Sensoreinheit zumindest einen Gassensor aufweisen, der in wenigstens einem Betriebszustand die Sensorkenngröße detektieren könnte. Die Sensoreinheit könnte beispielsweise das durch die Fluidleitung strömende Gas und/oder ein Feuergas, insbesondere einen Rauch, detektieren, der insbesondere bei einem Entzünden des durch die Fluidleitung strömenden Fluids entstehen könnte. Alternativ oder zusätzlich könnte die Sensoreinheit zumindest einen Temperatursensor aufweisen, der in wenigstens einem Betriebszustand eine Temperatur, insbesondere an einem Ausgang der Fluidleitung und/oder an zumindest einem Heizausgang, zu welchem die Fluidleitung führen könnte, detektieren könnte. Bei Abwesenheit einer Flamme, welche insbesondere durch ein Entzünden des durch die Fluidleitung strömenden Fluids entstehen könnte, und/oder eines durch die Fluidleitung strömenden Fluids, könnte die Sensoreinheit in wenigstens einem Betriebszustand insbesondere eine Temperatur der Flamme detektieren, wodurch bei angelegter zweiter elektrischer Spannung insbesondere eine Fehlfunktion der zweiten Ventileinheit gefolgert werden könnte. Bei Abwesenheit einer Flamme, welche insbesondere durch ein Entzünden des durch die Fluidleitung strömenden Fluids entstehen könnte, und/oder eines durch die Fluidleitung strömenden Fluids, könnte die Sensoreinheit in wenigstens einem Betriebszustand insbesondere eine Temperatur in dem Abschnitt der Fluidleitung und/oder an einem Ausgang der Fluidleitung und/oder an zumindest einem Heizausgang, zu welchem die Fluidleitung führen könnte, detektieren, wodurch bei angelegter zweiter elektrischer Spannung insbesondere eine Funktionstüchtigkeit, insbesondere eine korrekte Funktionsweise, der zweiten Ventileinheit gefolgert werden könnte. Dadurch kann insbesondere eine hohe Sicherheit für einen Bediener bereitgestellt und/oder eine Funktionstüchtigkeit zumindest einer der Ventileinheiten überprüft werden.According to the invention, the control unit is provided to use the sensor parameter to check at least one closed state of the second valve unit. The control unit is in particular provided to supply the coil with the second electrical voltage over a particularly predetermined period of time. For example, the particularly predetermined time period could assume a value in a range from 4 s to 7 s. In particular, the control unit is provided to supply the coil with a third electrical voltage after the in particular predetermined period of time when the second valve unit is in a sufficiently closed state, which third voltage may differ in particular from zero and / or may have a value of at least substantially zero. The third electrical voltage is in particular different from the first electrical voltage and from the second electrical voltage and in particular has a value which is in particular substantially smaller than a value of the first electrical voltage and as a value of the second electrical voltage. The control unit is provided in particular to output at least one warning and / or to prevent operation of a heating system having the gas valve device if the second valve unit is inadequate after the predetermined period of time. In this way, an operator can be informed of a malfunction, in particular before a complete defect in the second valve unit, whereby the second valve unit can in particular be replaced and / or a more reliable operation of a heating system having the gas valve device can be made possible. For example, the sensor unit could have at least one gas sensor, which could detect the sensor parameter in at least one operating state. The sensor unit could, for example, detect the gas flowing through the fluid line and / or a fire gas, in particular a smoke, which could arise in particular if the fluid flowing through the fluid line is ignited. Alternatively or additionally, the sensor unit could have at least one temperature sensor which, in at least one operating state, could detect a temperature, in particular at an outlet of the fluid line and / or at least one heating outlet, to which the fluid line could lead. In the absence of one Flame, which could arise, in particular, from an ignition of the fluid flowing through the fluid line and / or a fluid flowing through the fluid line, the sensor unit could in particular detect a temperature of the flame in at least one operating state, as a result of which in particular a malfunction of the flame when the second electrical voltage is applied second valve unit could be concluded. In the absence of a flame, which could arise in particular from an ignition of the fluid flowing through the fluid line and / or a fluid flowing through the fluid line, the sensor unit could, in at least one operating state, in particular a temperature in the section of the fluid line and / or at an outlet of the fluid line and / or at least one heating output, to which the fluid line could lead, so that when the second electrical voltage is applied, in particular functionality, in particular correct functioning, of the second valve unit could be inferred. As a result, a high level of safety can be provided for an operator and / or the functionality of at least one of the valve units can be checked.

Durch die erfindungsgemäße Ausgestaltung der Gasventilvorrichtung kann insbesondere eine hohe Flexibilität erreicht werden. Insbesondere können mittels verschiedener elektrischer Spannungen verschiedene Ventileinheiten geöffnet und/oder geschlossen werden. Besonders vorteilhaft können geringe Kosten erzielt werden. Es kann insbesondere durch einfache Programmierung der Ansteuereinheit, insbesondere durch einfache zusätzliche Programmierung der aus dem Stand der Technik bekannten Ansteuereinheit, eine Möglichkeit zu einer gezielten Ansteuerung einzelner der Ventileinheiten geschaffen werden. Insbesondere kann auf eine zweite Spule, welche insbesondere an der zweiten Ventileinheit angeordnet sein könnte, verzichtet werden. Insbesondere kann zumindest eine der Ventileinheiten durch die gezielte Ansteuerung auf eine Funktionsfähigkeit überprüft werden.A high degree of flexibility can in particular be achieved by the design of the gas valve device according to the invention. In particular, different valve units can be opened and / or closed by means of different electrical voltages. Low costs can be achieved particularly advantageously. In particular, by simple programming of the control unit, in particular by simple additional programming of the control unit known from the prior art, a possibility for targeted control of individual valve units can be created. In particular, a second coil, which could be arranged in particular on the second valve unit, can be dispensed with. In particular, at least one of the valve units can be checked for functionality by the targeted activation.

Ferner wird vorgeschlagen, dass bei angelegter erster elektrischer Spannung die Ventileinheiten beide geöffnet sind, wodurch insbesondere ein ungehinderter Durchfluss von Fluid, insbesondere von Gas, durch die Fluidleitung ermöglicht werden kann.It is further proposed that when the first electrical voltage is applied, the valve units are both open, which in particular enables an unimpeded flow of fluid, in particular gas, through the fluid line.

Bei Abwesenheit einer elektrischen Spannung an der Spule und/oder bei einer an der Spule anliegenden dritten elektrischen Spannung mit einem Wert von Null sind die Ventileinheiten insbesondere beide geschlossen. Insbesondere ist bei zumindest einer geschlossenen Ventileinheit ein Durchfluss von Fluid, insbesondere von Gas, durch die Fluidleitung wenigstens im Wesentlichen blockiert.In the absence of an electrical voltage on the coil and / or a third electrical voltage applied to the coil with a value of zero, the valve units are in particular both closed. In particular, at least one closed valve unit at least substantially blocks a flow of fluid, in particular gas, through the fluid line.

Beispielsweise könnte in Fluidströmungsrichtung betrachtet zunächst die zweite Ventileinheit und der zweiten Ventileinheit in Fluidströmungsrichtung nachgeschaltet die erste Ventileinheit angeordnet sein. Vorzugsweise ist die zweite Ventileinheit der ersten Ventileinheit in Fluidströmungsrichtung betrachtet nachgeschaltet. Insbesondere passiert ein, insbesondere bei angelegter erster elektrischer Spannung, durch die Fluidleitung in Fluidströmungsrichtung fließendes Fluid zunächst die erste Ventileinheit und anschließend die der ersten Ventileinheit nachgeschaltete zweite Ventileinheit. Dadurch kann bei geschlossenen Ventileinheiten die Fluidleitung insbesondere besonders sicher verschlossen werden.For example, viewed in the direction of fluid flow, the second valve unit could be arranged first and the first valve unit arranged downstream of the second valve unit in the direction of fluid flow. The second valve unit is preferably connected downstream of the first valve unit when viewed in the direction of fluid flow. In particular, a fluid flowing through the fluid line in the fluid flow direction, in particular when a first electrical voltage is applied, first passes the first valve unit and then the second valve unit downstream of the first valve unit. As a result, the fluid line can be closed particularly securely when the valve units are closed.

Weiterhin wird vorgeschlagen, dass die Gasventilvorrichtung zumindest ein Verbindungselement aufweist, das die erste Ventileinheit und die zweite Ventileinheit in wenigstens einem montierten Zustand magnetisch miteinander koppelt. Unter einem "Verbindungselement" soll insbesondere ein Element verstanden werden, welches dazu vorgesehen ist, ein von der Spule bereitgestelltes magnetisches Feld von der ersten Ventileinheit zu der zweiten Ventileinheit zu lenken. In wenigstens einem montierten Zustand überbrückt das Verbindungselement insbesondere einen Abstand zwischen der ersten Ventileinheit und der zweiten Ventileinheit wenigstens im Wesentlichen. Dadurch kann insbesondere auf eine zweite Spule, welche insbesondere an der zweiten Ventileinheit angeordnet sein könnte, verzichtet werden, wodurch insbesondere geringe Kosten ermöglicht werden können.It is further proposed that the gas valve device has at least one connecting element which magnetically couples the first valve unit and the second valve unit to one another in at least one assembled state. A “connecting element” is to be understood in particular as an element which is intended to direct a magnetic field provided by the coil from the first valve unit to the second valve unit. In at least one assembled state, the connecting element in particular bridges at least substantially a distance between the first valve unit and the second valve unit. As a result, in particular a second coil, which could in particular be arranged on the second valve unit, can be dispensed with, which in particular enables low costs.

Das Verbindungselement könnte beispielsweise ein von der Spule an der ersten Ventileinheit bereitgestelltes magnetisches Feld wenigstens im Wesentlichen unverändert an die zweite Ventileinheit lenken. Vorzugsweise überträgt das Verbindungselement ein von der Spule an der ersten Ventileinheit bereitgestelltes magnetisches Feld insbesondere wesentlich abgeschwächt an die zweite Ventileinheit. Beispielsweise könnte das Material, aus welchem das Verbindungselement wenigstens zu einem Großteil bestehen könnte, einen hohen magnetischen Übertragungswiderstand aufweisen. Insbesondere weist ein magnetisches Feld an der zweiten Spule einen Wert von maximal 90 %, insbesondere von maximal 80 %, vorteilhaft von maximal 70 % und vorzugsweise von maximal 60 % eines Werts des von der Spule an der ersten Ventileinheit bereitgestellten magnetischen Felds auf. Insbesondere weist ein magnetisches Feld an der zweiten Spule einen Wert von mindestens 10 %, insbesondere von mindestens 20 %, vorteilhaft von mindestens 30 % und vorzugsweise von mindestens 40 % eines Werts des von der Spule an der ersten Ventileinheit bereitgestellten magnetischen Felds auf. Dadurch kann insbesondere eine hohe Flexibilität erzielt und/oder die zweite Ventileinheit wenigstens teilweise unabhängig von der ersten Ventileinheit betätigt werden.The connecting element could, for example, direct a magnetic field provided by the coil on the first valve unit to the second valve unit at least substantially unchanged. The connecting element preferably transmits a magnetic field provided by the coil on the first valve unit, in particular in a substantially weakened manner, to the second valve unit. For example, the material from which the connecting element could consist at least in large part could have a high magnetic transmission resistance. In particular, a magnetic field on the second coil has a value of at most 90%, in particular at most 80%, advantageously at most 70% and preferably at most 60% of a value of the magnetic field provided by the coil on the first valve unit. In particular, a magnetic field points to the second coil has a value of at least 10%, in particular at least 20%, advantageously at least 30% and preferably at least 40% of a value of the magnetic field provided by the coil on the first valve unit. As a result, a high degree of flexibility can be achieved and / or the second valve unit can be actuated at least partially independently of the first valve unit.

Zudem wird vorgeschlagen, dass die erste Ventileinheit und zweite Ventileinheit unterschiedliche Schließkräfte aufweisen. Insbesondere sind zu einer Betätigung der ersten Ventileinheit und zu einer Betätigung der zweiten Ventileinheit verschiedene magnetische Felder, insbesondere verschiedene magnetische Feldstärken, vonnöten. Unter einer "Schließkraft" einer Ventileinheit soll insbesondere eine Kraft verstanden werden, welche vonnöten ist, um die Ventileinheit ausgehend von einem geöffneten Zustand der Ventileinheit in einen geschlossenen Zustand der Ventileinheit zu überführen. Die Schließkraft einer Ventileinheit ist insbesondere wenigstens im Wesentlichen definiert, insbesondere bestimmt und/oder festgelegt, durch zumindest eine Federkonstante des Federelements der Ventileinheit und/oder durch zumindest eine Magnetisierbarkeit des Ventilelements der Ventileinheit und/oder durch zumindest eine Magnetisierbarkeit zumindest eines mit dem Ventilelement der Ventileinheit verbundenen Elements und/oder durch zumindest einen Reibungskoeffizienten zumindest einer Reibung, welche insbesondere bei einer Bewegung des Ventilelements relativ zu dem Ventilgehäuse auftritt. Ein erstes Federelement der ersten Ventileinheit und ein zweites Federelement der zweiten Ventileinheit weisen insbesondere verschiedene Federkonstanten auf. Dadurch kann insbesondere eine bedarfsgerechte Ansteuerung und/oder Betätigung der Ventileinheiten ermöglicht werden.It is also proposed that the first valve unit and the second valve unit have different closing forces. In particular, different magnetic fields, in particular different magnetic field strengths, are required to actuate the first valve unit and to actuate the second valve unit. A “closing force” of a valve unit is to be understood in particular as a force which is necessary in order to convert the valve unit from an open state of the valve unit to a closed state of the valve unit. The closing force of a valve unit is in particular at least essentially defined, in particular determined and / or fixed, by at least one spring constant of the spring element of the valve unit and / or by at least one magnetisability of the valve element of the valve unit and / or by at least one magnetisability of the valve element Valve unit connected element and / or by at least one coefficient of friction of at least one friction, which occurs in particular when the valve element moves relative to the valve housing. A first spring element of the first valve unit and a second spring element of the second valve unit have, in particular, different spring constants. In particular, this enables the valve units to be controlled and / or actuated as required.

Eine besonders hohe Flexibilität kann insbesondere erreicht werden durch ein Heizsystem mit zumindest einer erfindungsgemäßen Gasventilvorrichtung. Das Heizsystem könnte beispielsweise einen insbesondere kombinierten Brennwertkessel und/oder einen insbesondere kombinierten Boiler aufweisen. Alternativ oder zusätzlich könnte das Heizsystem beispielsweise Vorrichtungen aufweisen, welche zumindest zwei Ventileinheiten, insbesondere zumindest zwei Fluidventileinheiten, aufweisen könnte, wie beispielsweise einen Brenner und/oder eine Gasventilvorrichtung mit mehreren Gasventileinheiten.A particularly high degree of flexibility can be achieved in particular by a heating system with at least one gas valve device according to the invention. The heating system could have, for example, a combined condensing boiler and / or a combined boiler. As an alternative or in addition, the heating system could, for example, have devices which could have at least two valve units, in particular at least two fluid valve units, such as a burner and / or a gas valve device with a plurality of gas valve units.

Eine Flexibilität kann insbesondere weiter gesteigert werden durch ein Verfahren zu einem Betrieb zumindest einer erfindungsgemäßen Gasventilvorrichtung, mit zumindest einer ersten Ventileinheit und zumindest einer zweiten Ventileinheit, durch die eine Fluidleitung wenigstens im Wesentlichen geöffnet und/oder geschlossen wird, mit zumindest einer Spule, durch welche die erste Ventileinheit und die zweite Ventileinheit angesteuert wird und vorzugsweise beide Ventileinheiten angesteuert werden und welche besonders bevorzugt an der ersten Ventileinheit angeordnet sind, wobei die Spule zur Ansteuerung der Ventileinheiten mit zumindest einer elektrischen Spannung versorgt wird, wobei die Spule in zumindest einem ersten Betriebszustand mit zumindest einer ersten elektrischen Spannung und in zumindest einem zweiten Betriebszustand mit zumindest einer von der ersten elektrischen Spannung insbesondere wesentlich verschiedenen zweiten elektrischen Spannung versorgt wird, welche beide von Null verschieden sind und wobei bei angelegter zweiter elektrischer Spannung die erste Ventileinheit geöffnet und die zweite Ventileinheit geschlossen wird.Flexibility can in particular be further increased by a method for operating at least one gas valve device according to the invention, with at least one a first valve unit and at least one second valve unit, by means of which a fluid line is at least substantially opened and / or closed, with at least one coil, by means of which the first valve unit and the second valve unit are activated and preferably both valve units are activated and which are particularly preferably activated are arranged in the first valve unit, the coil for controlling the valve units being supplied with at least one electrical voltage, the coil in particular with at least one first voltage in at least one first operating state and with at least one of the first electrical voltage in at least one second operating state in particular substantially different second electrical voltage is supplied, both of which are different from zero and, when the second electrical voltage is applied, the first valve unit is opened and the second valve unit is closed.

Die Gasventilvorrichtung 10 weist eine Spule 18 auf. In einem montierten Zustand ist die Spule 18 an der ersten Ventileinheit 12 angeordnet. Die Spule 18 stellt in einem Betriebszustand ein magnetisches Feld an der ersten Ventileinheit 12 bereit. Die Spule 18 ist zu einer Betätigung der Ventileinheiten 12, 14 vorgesehen. In Abhängigkeit einer Ansteuerung durch eine Ansteuereinheit 20 betätigt die Spule 18 in einem Betriebszustand die Ventileinheiten 12, 14.The gas valve device 10 has a coil 18. In an assembled state, the coil 18 is arranged on the first valve unit 12. The coil 18 provides a magnetic field on the first valve unit 12 in an operating state. The coil 18 is provided for actuating the valve units 12, 14. Depending on a control by a control unit 20, the coil 18 actuates the valve units 12, 14 in an operating state.

Die Gasventilvorrichtung 10 weist die Ansteuereinheit 20 auf (vgl. Fig. 1). In einem Betriebszustand steuert die Ansteuereinheit 20 die Ventileinheiten 12, 14 mittels der Spule 18 an. Zu einer Ansteuerung der Ventileinheiten 12, 14 versorgt die Ansteuereinheit 20 die Spule 18 mit elektrischen Spannungen. Im Folgenden werden beispielhaft drei verschiedene elektrische Spannungen beschrieben, welche drei verschiedene Zustände der beiden Ventileinheiten nach sich ziehen.The gas valve device 10 has the control unit 20 (cf. Fig. 1 ). In an operating state, the control unit 20 controls the valve units 12, 14 by means of the coil 18. To control the valve units 12, 14, the control unit 20 supplies the coil 18 with electrical voltages. In the following, three different electrical voltages are described as examples, which result in three different states of the two valve units.

In einem ersten Betriebszustand versorgt die Ansteuereinheit 20 die Spule 18 mit einer ersten elektrischen Spannung, welche von Null verschieden ist. Bei angelegter erster elektrischer Spannung sind die Ventileinheiten 12, 14 beide geöffnet (vgl. Fig. 2). Die Fluidleitung 16 ist bei angelegter erster elektrischer Spannung geöffnet und zu einem Durchfluss von Fluid geeignet. Bei angelegter erster elektrischer Spannung fließt in einem ersten Betriebszustand Fluid im Wesentlichen ungehindert durch die Fluidleitung 16.In a first operating state, the control unit 20 supplies the coil 18 with a first electrical voltage which is different from zero. When the first electrical voltage is applied, the valve units 12, 14 are both open (cf. Fig. 2 ). The fluid line 16 is open when the first electrical voltage is applied and is suitable for a flow of fluid. When a first electrical voltage is applied, fluid flows through the fluid line 16 essentially unhindered in a first operating state.

In einem zweiten Betriebszustand versorgt die Ansteuereinheit 20 die Spule 18 mit einer von der ersten elektrischen Spannung verschiedenen zweiten elektrischen Spannung, welche von Null verschieden ist. Die zweite elektrische Spannung weist einen Wert auf, welcher wesentlich kleiner ist als ein Wert der ersten elektrischen Spannung. Bei angelegter zweiter elektrischer Spannung ist die erste Ventileinheit 12 geöffnet und die zweite Ventileinheit 14 geschlossen (vgl. Fig. 3). Die Fluidleitung 16 ist bei angelegter zweiter elektrischer Spannung durch die zweite Ventileinheit 14 geschlossen. Bei angelegter zweiter elektrischer Spannung ist in einem zweiten Betriebszustand ein Durchfluss von Fluid durch die Fluidleitung 16 durch die zweite Ventileinheit 14 im Wesentlichen blockiert.In a second operating state, the control unit 20 supplies the coil 18 with a second electrical voltage which is different from the first electrical voltage and which is different from zero. The second electrical voltage has a value that is significantly smaller than a value of the first electrical voltage. When a second electrical voltage is applied, the first valve unit 12 is open and the second valve unit 14 is closed (cf. Fig. 3 ). The fluid line 16 is closed by the second valve unit 14 when a second electrical voltage is applied. When a second electrical voltage is applied, a flow of fluid through the fluid line 16 through the second valve unit 14 is essentially blocked in a second operating state.

Zu einer Überprüfung eines Schließzustands der zweiten Ventileinheit 14 weist die Gasventilvorrichtung 10 eine Sensoreinheit 24 auf (vgl. Fig. 1). In einem Betriebszustand, insbesondere in einem zweiten Betriebszustand, detektiert die Sensoreinheit 24 eine Sensorkenngröße hinsichtlich einer Anwesenheit von Fluid in einem Abschnitt 26 der Fluidleitung 16 (vgl. Fig. 2 bis 4). In Fluidströmungsrichtung 22 betrachtet ist der Abschnitt 26 der Fluidleitung 16 der zweiten Ventileinheit 14 nachgeschaltet. Die Sensoreinheit 24 übermittelt in einem Betriebszustand, insbesondere in einem zweiten Betriebszustand, die Sensorkenngröße an die Ansteuereinheit 20. In einem Betriebszustand, insbesondere in einem zweiten Betriebszustand, überprüft die Ansteuereinheit 20 mittels der Sensorkenngröße einen Schließzustand der zweiten Ventileinheit 14.To check a closed state of the second valve unit 14, the gas valve device 10 has a sensor unit 24 (cf. Fig. 1 ). In an operating state, in particular in a second operating state, the sensor unit 24 detects a sensor parameter with regard to the presence of fluid in a section 26 of the fluid line 16 (cf. 2 to 4 ). When viewed in the direction of fluid flow 22, section 26 of the fluid line 16 is connected downstream of the second valve unit 14. In one operating state, in particular in a second operating state, the sensor unit 24 transmits the sensor parameter to the control unit 20. In an operating state, in particular in a second operating state, the control unit 20 uses the sensor parameter to check a closed state of the second valve unit 14.

Im vorliegenden Ausführungsbeispiel detektiert die Sensoreinheit 24 in einem Betriebszustand, insbesondere in einem zweiten Betriebszustand, eine Anwesenheit oder eine Abwesenheit einer Flamme an dem Heizausgang 32. Die Ansteuereinheit 20 überprüft in einem Betriebszustand, insbesondere in einem zweiten Betriebszustand, mittels der Sensorkenngröße, ob bei anliegender zweiter elektrischer Spannung eine Entzündung einer Flamme an dem Heizausgang 32 möglich ist. In dem in Fig. 3 dargestellten Fall ist die zweite Ventileinheit 14 in einem zweiten Betriebszustand bei anliegender zweiter elektrischer Spannung vollständig geschlossen. In einem zweiten Betriebszustand ist bei anliegender zweiter elektrischer Spannung eine Entzündung einer Flamme an dem Heizausgang 32 unmöglich.In the present exemplary embodiment, the sensor unit 24 detects the presence or absence of a flame at the heating outlet 32 in an operating state, in particular in a second operating state. The control unit 20 checks in an operating state, in particular in a second operating state, by means of the sensor parameter whether it is present second electrical voltage an ignition of a flame at the heating output 32 is possible. In the in Fig. 3 In the illustrated case, the second valve unit 14 is completely closed in a second operating state when the second electrical voltage is present. In a second operating state, ignition of a flame at the heating output 32 is impossible when the second electrical voltage is present.

Die Gasventilvorrichtung 10 weist ein Verbindungselement 28 auf (vgl. Fig. 2 bis 4). Das Verbindungselement 28 besteht zu einem Großteil aus einem metallischen Material, wie beispielsweise aus einem Blech. In einem montierten Zustand koppelt das Verbindungselement 28 die erste Ventileinheit 12 und die zweite Ventileinheit 14 magnetisch miteinander. Das Verbindungselement 28 überträgt in einem Betriebszustand, insbesondere in einem ersten Betriebszustand und/oder in einem zweiten Betriebszustand und/oder in einem dritten Betriebszustand, ein von der Spule 18 an der ersten Ventileinheit 12 bereitgestelltes magnetisches Feld wesentlich abgeschwächt an die zweite Ventileinheit 14.The gas valve device 10 has a connecting element 28 (cf. 2 to 4 ). The connecting element 28 consists largely of a metallic material, such as a sheet metal. In an assembled state, the connecting element 28 magnetically couples the first valve unit 12 and the second valve unit 14 to one another. In one operating state, in particular in a first operating state and / or in a second operating state and / or in a third operating state, the connecting element 28 transmits a magnetic field provided by the coil 18 on the first valve unit 12 to the second valve unit 14 in a substantially weakened manner.

Bei angelegter erster elektrischer Spannung ist ein von der Spule 18 an der ersten Ventileinheit 12 bereitgestelltes magnetisches Feld ausreichend, um die erste Ventileinheit 12 zu öffnen und/oder geöffnet zu halten. Bei angelegter erster elektrischer Spannung ist ein von der Spule 18 an der ersten Ventileinheit 12 bereitgestelltes und von dem Verbindungselement 28 an die zweite Ventileinheit 14 gelenktes magnetisches Feld ausreichend, um die zweite Ventileinheit 14 zu öffnen und/oder geöffnet zu halten.When the first electrical voltage is applied, a magnetic field provided by the coil 18 on the first valve unit 12 is sufficient to open and / or keep the first valve unit 12 open. When the first electrical is applied Voltage is a magnetic field provided by the coil 18 on the first valve unit 12 and directed by the connecting element 28 to the second valve unit 14 sufficient to open and / or keep the second valve unit 14 open.

Bei angelegter zweiter elektrischer Spannung ist ein von der Spule 18 an der ersten Ventileinheit 12 bereitgestelltes magnetisches Feld ausreichend, um die erste Ventileinheit 12 zu öffnen und/oder geöffnet zu halten. Bei angelegter zweiter elektrischer Spannung ist ein von der Spule 18 an der ersten Ventileinheit 12 bereitgestelltes und von dem Verbindungselement 28 an die zweite Ventileinheit 14 gelenktes magnetisches Feld unzureichend, um die zweite Ventileinheit 14 zu öffnen und/oder geöffnet zu halten.When the second electrical voltage is applied, a magnetic field provided by the coil 18 on the first valve unit 12 is sufficient to open and / or keep the first valve unit 12 open. When the second electrical voltage is applied, a magnetic field provided by the coil 18 on the first valve unit 12 and directed by the connecting element 28 to the second valve unit 14 is insufficient to open and / or keep the second valve unit 14 open.

Die erste Ventileinheit 12 und die zweite Ventileinheit 14 weisen unterschiedliche Schließkräfte auf. Eine Federkonstante des ersten Federelements 40 und eine Federkonstante des zweiten Federelements 46 weisen voneinander verschiedene Werte auf, welche beide von Null verschieden sind. Beispielsweise könnte die erste Ventileinheit eine Schließkraft aufweisen, welche im Wesentlichen 150 mbar entsprechen könnte. Beispielsweise könnte die zweite Ventileinheit eine Schließkraft aufweisen, welche im Wesentlichen 50 mbar entsprechen könnte.The first valve unit 12 and the second valve unit 14 have different closing forces. A spring constant of the first spring element 40 and a spring constant of the second spring element 46 have mutually different values, both of which are different from zero. For example, the first valve unit could have a closing force, which could essentially correspond to 150 mbar. For example, the second valve unit could have a closing force which could essentially correspond to 50 mbar.

In einem dritten Betriebszustand versorgt die Ansteuereinheit 20 die Spule 18 mit einer von der ersten elektrischen Spannung und von der zweiten elektrischen Spannung verschiedenen dritten elektrischen Spannung. Die dritte elektrische Spannung weist einen Wert auf, welcher wesentlich kleiner ist als ein Wert der zweiten elektrischen Spannung. Bei angelegter dritter elektrischer Spannung sind die Ventileinheiten 12, 14 beide geschlossen (vgl. Fig. 4). Die Fluidleitung 16 ist bei angelegter dritter elektrischer Spannung durch die Ventileinheiten 12, 14 geschlossen. Bei angelegter dritter elektrischer Spannung ist in einem dritten Betriebszustand ein Durchfluss von Fluid durch die Fluidleitung 16 durch die Ventileinheiten 12, 14 im Wesentlichen blockiert.In a third operating state, the control unit 20 supplies the coil 18 with a third electrical voltage that is different from the first electrical voltage and from the second electrical voltage. The third electrical voltage has a value that is significantly smaller than a value of the second electrical voltage. When a third electrical voltage is applied, the valve units 12, 14 are both closed (cf. Fig. 4 ). The fluid line 16 is closed by the valve units 12, 14 when a third electrical voltage is applied. When a third electrical voltage is applied, a flow of fluid through the fluid line 16 through the valve units 12, 14 is essentially blocked in a third operating state.

Die Ansteuereinheit 20 versorgt die Spule 18 in einem dritten Betriebszustand mit der dritten elektrischen Spannung im Anschluss an eine Überprüfung eines Schließzustands der zweiten Ventileinheit 14, und zwar insbesondere im Fall eines korrekten Schließzustands der zweiten Ventileinheit 14 und/oder bei fehlgeschlagener Entzündung einer Flamme an dem Heizausgang 32.The control unit 20 supplies the coil 18 in a third operating state with the third electrical voltage following a check of a closed state of the second valve unit 14, in particular in the case of a correct closed state of the second valve unit 14 and / or in the event of a failed ignition of a flame on the Heating output 32.
