Description
Gasregelgerät Gas Regulator
Die Erfindung betrifft ein Gasregelgerät nach dem Oberbegriff des Anspruchs 1 bzw. nach dem Oberbegriff des Anspruchs 7.The invention relates to a gas control device according to the preamble of claim 1 and according to the preamble of claim 7.
Gasregelgeräte verfügen über mindestens ein Ventil. Jedes Ventil verfügt über einen Ventilkörper und einen Ventilsitz, wobei in geschlossener Position des jeweiligen Ventils der Ventilkörper über ein Federelement gegen den Ventilsitz des jeweiligen Ventils gedrückt wird, um so das Ventil geschlossen zu halten. Bei aus der Praxis bekannten Gasregelgeräten ist jedem Ventil neben dem Federelement weiterhin eine Spule zugeordnet, wobei mit Hilfe der dem jeweiligen Ventil zugeordneten Spule der Ventilkörper entgegen der vom Federelement bereitgestellten Federkraft sowie entgegen einer am Ventil anliegenden Druckdifferenz geöffnet werden kann.Gas control units have at least one valve. Each valve has a valve body and a valve seat, wherein in the closed position of the respective valve, the valve body is pressed by a spring element against the valve seat of the respective valve so as to keep the valve closed. In known from practice gas control units each valve next to the spring element is further associated with a coil, which can be opened against the spring force supplied by the spring element and against a voltage applied to the valve pressure difference with the aid of the respective valve associated spool.
Zum öffnen eines Ventils eines Gasregelgeräts muss demnach die dem Ventil zugeordnete Spule die Federkraft des dem Ventil zugeordneten Federelements sowie die am Ventil herrschende Druckdifferenz überwinden. Das von der Spule bereitzustellende magnetische Feld ist beim öffnen des Ventils maximal, nach dem öffnen des Ventils hingegen sinkt das benötigte magnetische Feld, welches von der dem jeweiligen Ventil zugeordneten Spule bereitgestellt werden muss. Die einem Ventil eines Gasregelgerätes zugeordnete Spule muss jedoch derart ausgelegt sein, dass das beim Öffnen des Ventils benötigte magnetische Feld bereitgestellt werden kann. Hierdurch ergeben sich relativ groß dimensio- nierte Spulen, die einerseits teuer und andererseits schwer sind. Es besteht daher ein Bedarf an einem Gasregelgerät, welches mit kleineren und kostengünstigeren Spulen die erforderliche Funktionalität bereitstellen kann.
Hiervon ausgehend liegt der Erfindung das Problem zu Grunde, ein neuartiges Gasregelgerät zu schaffen.In order to open a valve of a gas control device, therefore, the coil associated with the valve must overcome the spring force of the spring element associated with the valve as well as the pressure difference prevailing at the valve. The magnetic field to be provided by the coil is maximum when the valve is opened, but after opening the valve, the required magnetic field decreases, which must be provided by the coil associated with the respective valve. However, the coil associated with a valve of a gas governor must be designed so that the magnetic field required to open the valve can be provided. This results in relatively large sized coils, which are both expensive and heavy. There is therefore a need for a gas control device which can provide the required functionality with smaller and less expensive coils. On this basis, the invention is based on the problem of creating a novel gas control device.
Dieses Problem wird nach einem ersten Aspekt der Erfindung durch ein Gasre- gelgerät mit den Merkmalen des Anspruchs 1 gelöst. Hiernach sind dem oder jedem Ventil jeweils mindestens zwei Spulen zugeordnet, wobei zum Öffnen des jeweiligen Ventils mindestens zwei der dem jeweiligen Ventil zugeordneten Spulen parallel geschaltet sind, und wobei nach dem Öffnen des jeweiligen Ventils die zuvor parallel geschalteten Spulen in Reihe geschaltet sind.This problem is solved according to a first aspect of the invention by a gas regulator device having the features of claim 1. According to this, at least two coils are assigned to the or each valve, at least two of the coils associated with the respective valve being connected in parallel to open the respective valve, and after the respective valve has been opened, the previously parallel-connected coils are connected in series.
Nach dem ersten Aspekt der hier vorliegenden Erfindung sind jedem Ventil des Gasregelgeräts mindestens zwei Spulen zugeordnet. Zum Öffnen des jeweiligen Ventils sind demselben zugeordnete Spulen parallel geschaltet. Nach dem Öffnen des jeweiligen Ventils hingegen sind die zuvor parallel geschalteten Spulen in Reihe geschaltet. Hierdurch ist es möglich mit relativ kleinen, kostengünstigen Spulen, das zum Öffnen des Ventils benötigte magnetische Feld bereitzustellen. Nach dem ersten Aspekt der hier vorliegenden Erfindung kann jedes Ventil eines Gasregelgeräts unabhängig von anderen Ventilen desselben geöffnet und geschlossen werden.According to the first aspect of the present invention, at least two coils are associated with each valve of the gas control device. To open the respective valve associated coils are connected in parallel. After opening the respective valve, however, the previously parallel-connected coils are connected in series. This makes it possible with relatively small, inexpensive coils to provide the magnetic field required to open the valve. According to the first aspect of the present invention, each valve of a gas control device can be opened and closed independently of other valves thereof.
Nach einem zweiten Aspekt der Erfindung wird dieses Problem durch ein Gasregelgerät mit den Merkmalen des Anspruchs 7 gelöst. Hiernach sind zum Öffnen der Ventile die denselben zugeordneten Spulen parallel geschaltet, wobei nach dem Öffnen der Ventile die zuvor parallel geschalteten Spulen in Reihe geschaltet sind.According to a second aspect of the invention, this problem is solved by a gas control device having the features of claim 7. Thereafter, to open the valves, the same associated coils are connected in parallel, wherein after opening the valves, the previously parallel-connected coils are connected in series.
Nach dem zweiten Aspekt der hier vorliegenden Erfindung sind mindestens zwei in Reihe geschalteten Ventilen mindestens zwei gemeinsame Spulen zugeordnet, die zum öffnen der Ventile parallel geschaltet und nach dem Öffnen der Ventile in Reihe geschaltet sind. Die so in Reihe geschalteten Ventile können unabhängig voneinander geöffnet jedoch nur gemeinsam geschlossen werden.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Nachfolgend werden Ausführungsbeispiele der Erfindung, ohne hierauf beschränkt zu sein, anhand der Zeich- nung näher erläutert. In der Zeichnung zeigt:According to the second aspect of the present invention, at least two valves connected in series are associated with at least two common coils, which are connected in parallel to open the valves and connected in series after opening the valves. The valves connected in series can be opened independently of each other, but only closed together.

Ein bevorzugtes Ausführungsbeispiel der hier vorliegende Erfindung wird nachfolgend unter Bezugnahme auf Fig. 1 bis 3 im Detail beschrieben, wobei Fig. 1 einen Querschnitt durch ein Gasregelventil 10 mit zwei in Reihe geschalteten Ventilen 11 , 12 zeigt. Jedes der Ventile 11 , 12 verfügt über einen Ventilkörper 13, 14, und einen Ventilsitz 15, 16, wobei jedem der Ventile 11 , 12 ein Federelement 17, 18 zugeordnet ist, welches den jeweiligen Ventilkörper 13, 14, gegen den jeweiligen Ventilsitz 15, 16 des jeweiligen Ventils 11 , 12 drückt und so das jeweilige Ventil 11 , 12 geschlossen hält.A preferred embodiment of the present invention will be described below in detail with reference to Figs. 1 to 3, wherein Fig. 1 shows a cross section through a gas control valve 10 with two valves 11, 12 connected in series. Each of the valves 11, 12 has a valve body 13, 14, and a valve seat 15, 16, wherein each of the valves 11, 12, a spring element 17, 18 is associated, which the respective valve body 13, 14, against the respective valve seat 15, 16 of the respective valve 11, 12 presses and so the respective valve 11, 12 holds closed.
Zum Öffnen eines Ventils 11 , 12 muss der Ventilkörper 13, 14 des jeweiligen Ventils 11 , 12 entgegen der vom Federelement 17, 18 bereitgestellten Federkraft und entgegen der am Ventilkörper herrschenden Druckdifferenz vom je- weiligen Ventilsitz 15, 16 abgehoben werden.
Im Ausführungsbeispiel der Fig. 1 bis 3 sind hierzu jedem der beiden Ventile 11 , 12 zwei Spulen 19, 20 zugeordnet. Zum Öffnen des jeweiligen Ventils 11 , 12 sind die demselben zugeordneten Spulen 19, 20 parallel geschaltet (siehe Fig. 2), nach dem Öffnen des jeweiligen Ventils 11 , 12 sind hingegen die zuvor pa- rallel geschalteten Spulen 19, 20 in Reihe geschaltet (siehe Fig. 3). Es sei darauf hingewiesen, dass, obwohl im gezeigten Ausführungsbeispiel jedem Ventil 11 , 12 ausschließlich zwei Spulen 19, 20 zugeordnet sind, es auch möglich ist, dass jedem der Ventile 11, 12 mehr als zwei Spulen zugeordnet sind.In order to open a valve 11, 12, the valve body 13, 14 of the respective valve 11, 12 must be lifted from the respective valve seat 15, 16 against the spring force provided by the spring element 17, 18 and counter to the pressure difference prevailing on the valve body. In the exemplary embodiment of FIGS. 1 to 3, two coils 19, 20 are assigned to each of the two valves 11, 12 for this purpose. To open the respective valve 11, 12 are the same associated coils 19, 20 connected in parallel (see Fig. 2), after the opening of the respective valve 11, 12, however, the previously parallel-connected coils 19, 20 are connected in series ( see Fig. 3). It should be noted that, although in the embodiment shown each valve 11, 12 are associated with only two coils 19, 20, it is also possible that each of the valves 11, 12 more than two coils are assigned.
Zum Öffnen des jeweiligen Ventils sind gemäß Fig. 2 alle demselben zugeordneten Spulen 19, 20 parallel geschaltet. Nach dem Öffnen des jeweiligen Ventils sind gemäß Fig. 2 alle demselben zugeordneten Spulen 19, 20 in Reihe geschaltet.To open the respective valve, all the coils 19, 20 associated with them are connected in parallel, as shown in FIG. After the opening of the respective valve, as shown in FIG. 2, all the coils 19, 20 assigned to it are connected in series.
In dem Fall, in welchem im gezeigten Ausführungsbeispiel die jedem der Ventile 11 , 12 zugeordneten beiden Spulen 19, 20 identisch ausgeführt sind und über einen identischen ohmschen Widerstand R verfügen, beträgt beim öffnen des jeweiligen Ventils 11 , 12 der gesamte ohmsche Widerstand Rparaiiei der parallel geschalteten Spulen 0,5*R. Nach dem Öffnen des jeweiligen Ventils, nämlich dann, wenn die Spulen 19, 20 in Reihe geschaltet sind, beträgt der gesamte ohmsche Widerstand RReihe der in Reihe geschalteten Spulen 2*R.In the case in which, in the embodiment shown, the two coils 19, 20 assigned to each of the valves 11, 12 are identical and have an identical ohmic resistance R, the total ohmic resistance R pa is raiiei when the respective valve 11, 12 is opened of parallel coils 0.5 * R. After opening the respective valve, namely when the coils 19, 20 are connected in series, the total ohmic resistance R Re ihe of the series-connected coils 2 * R.
Nach dem Umschalten von der Parallelschaltung in die Reihenschaltung der Spulen 19, 20 verändert sich demnach der Gesamtwiderstand der Anordnung aus den beiden Spulen 19, 20 um den Faktor 4, woraus folgt, dass sich auch der durch die Spulen 19, 20 fließende elektrische Strom um den Faktor 4 ändert.After switching from the parallel circuit into the series connection of the coils 19, 20, the total resistance of the arrangement of the two coils 19, 20 thus changes by a factor of 4, from which it follows that the electrical current flowing through the coils 19, 20 also changes the factor 4 changes.
Der Faktor, um welchen sich der Gesamtwiderstand der Spulenanordnung und der durch dieselbe fließende Strom ändert, ist selbstverständlich von der Anzahl der Spulen und der Dimensionierung derselben abhängig.
Wie Fig. 2 und 3 entnommen werden kann, sind den Spulen 19, 20 ansteuerbare Schaltelemente 21 zugeordnet. Abhängig von der Schaltstellung der Schaltelemente 21 sind die einem Ventil 11 , 12 zugeordneten Spulen 19, 20 entweder parallel oder in Reihe geschaltet. Zum Öffnen eines Ventils 11 , 12, werden die ansteuerbaren Schaltelemente 21 derart angesteuert, dass dieselben die in Fig. 2 dargestellte Schaltstellung einnehmen und die Spulen 19, 20 demnach parallel geschaltet sind. Nach dem Öffnen des jeweiligen Ventils 11 , 12 wird die Ansteuerung der Schaltelemente 21 derart geändert, dass dieselben die in Fig. 3 dargestellte Schaltstellung einnehmen und die Spulen 19, 20 demnach in Reihe geschaltet sind.The factor by which the total resistance of the coil arrangement and the current flowing through it varies, of course, depends on the number of coils and the dimensioning of the same. As can be seen in FIGS. 2 and 3, the switching elements 21 are assigned to the coils 19, 20. Depending on the switching position of the switching elements 21, the associated with a valve 11, 12 coils 19, 20 are connected either in parallel or in series. To open a valve 11, 12, the controllable switching elements 21 are driven such that they occupy the switching position shown in Fig. 2 and the coils 19, 20 are therefore connected in parallel. After opening the respective valve 11, 12, the control of the switching elements 21 is changed such that they occupy the switching position shown in Fig. 3 and the coils 19, 20 are therefore connected in series.
Vorzugsweise sind die einem Ventil 11 , 12 zugeordneten Spulen identisch dimensioniert, wobei die Spulen 19, 20 eines jeden Ventils 11 , 12 phasengleich ausgeführt sind.Preferably, the coils associated with a valve 11, 12 are dimensioned identically, wherein the coils 19, 20 of each valve 11, 12 are executed in phase.
Die Richtung des durch die Spule 19, 20 fließenden elektrischen Stroms sowie die Richtung des von denselben bereitgestellten magnetischen Felds ist gleichsinnig, sodass dieselben zum öffnen des jeweiligen Ventils 11 , 12 das erforderliche magnetische Feld bereitstellen können.The direction of the electric current flowing through the coil 19, 20 and the direction of the magnetic field provided therefrom are in the same direction, so that they can provide the required magnetic field for opening the respective valve 11, 12.
Im gezeigten Ausführungsbeispiel sind jedem der Ventile 11 , 12 des Gasregelgeräts 10 jeweils zwei Spulen 19, 20 mit entsprechenden Schaltelementen 21 zugeordnet. Jedes der beiden Ventile 11 , 12 kann demnach unabhängig vom anderen Ventil 12, 11 geöffnet und geschlossen werden.In the illustrated embodiment, each of the valves 11, 12 of the gas control device 10 are each associated with two coils 19, 20 with corresponding switching elements 21. Each of the two valves 11, 12 can therefore be opened and closed independently of the other valve 12, 11.
Fig. 4, 5 zeigen ein alternatives Ausführungsbeispiel der Erfindung, bei welchem jedem der beiden Ventile 11 , 12 vier Spulen 19a, 19b, 20a, 20b zugeordnet. Zum Öffnen des jeweiligen Ventils 11 , 12 sind eine Teilmenge, nämlich mindestens zwei, der demselben zugeordneten Spulen 19a, 19b, 2Oa1 20b pa- rallel geschaltet (siehe Fig. 4), nach dem Öffnen des jeweiligen Ventils 11 , 12 sind die zuvor parallel geschalteten Spulen 19a, 19b, 20a, 20b in Reihe geschaltet (siehe Fig. 5).
Im Unterschied hierzu ist es auch möglich, dass im gezeigten Ausführungsbeispiel der Fig. 1 den beiden in Reihe geschalteten Ventilen zwei gemeinsame Spulen zugeordnet sind, die zum Öffnen der beiden Ventile parallel geschaltet und nach dem Öffnen der beiden Ventile in Reihe geschaltet sind. In diesem Fall können dann die beiden Ventile unabhängig voneinander geöffnet jedoch nur gemeinsam geschlossen werden.
Figures 4, 5 show an alternative embodiment of the invention in which each of the two valves 11, 12 is associated with four coils 19a, 19b, 20a, 20b. To open the respective valve 11, 12, a subset, namely at least two, of the coils associated therewith 19a, 19b, 2Oa 1 20b connected in parallel (see Fig. 4), after opening the respective valve 11, 12 are the previously connected in parallel coils 19a, 19b, 20a, 20b connected in series (see Fig. 5). In contrast, it is also possible that in the embodiment shown in FIG. 1 the two valves connected in series are associated with two common coils, which are connected in parallel to open the two valves and connected in series after opening the two valves. In this case, then the two valves can be opened independently but only closed together.
