Abstract
Description
Die Erfindung betrifft eine Ventilvorrichtung zur Unterbrechung der Gaszufuhr einer Versorgungsleitung.The invention relates to a valve device for interrupting the gas supply of a supply line.
Gasdruckregler (optional mit Sicherheitsventil) sind bekannt. Sie werden zwischen Gasversorgungsleitung und Endverbraucher aus Sicherheitsgründen installiert. Die Funktion besteht darin, den Gasdruck auf der Endverbraucherseite bei unterschiedlichen Durchflüssen konstant zu halten und Druckschwankungen in der Versorgungsleitung auszugleichen. Außerdem wird bei zu hohem Eingangsdruck die Gaszufuhr durch die Überdruckabschaltung des Gasdruckreglers unterbrochen.Gas pressure regulators (optional with safety valve) are known. They are installed between the gas supply line and the end user for safety reasons. The function is to keep the gas pressure on the consumer side at different flow rates constant and to compensate for pressure fluctuations in the supply line. In addition, at too high inlet pressure, the gas supply is interrupted by the overpressure shutdown of the gas pressure regulator.
Aufgabe der Erfindung ist es, eine Ventilvorrichtung zu schaffen, die eine flexiblere Unterbrechung der Gaszufuhr ermöglicht.The object of the invention is to provide a valve device which allows a more flexible interruption of the gas supply.
Zur Lösung dieser Aufgabe wird eine Ventilvorrichtung zur Unterbrechung der Gaszufuhr einer Versorgungsleitung vorgeschlagen, die dadurch gekennzeichnet ist, dass sie ein Ventil umfasst, das mittel eines externen Signals, insbesondere eines elektrischen Signals, steuerbar ist. Die Erfindung beruht auf der Erkenntnis, dass mit einem rein mechanisch arbeitenden Druckregler die Gaszufuhr nur bei Vorliegen eines Überdrucks in der Gasversorgungsleitung unterbrochen werden kann, wobei der Grenzwert für den Überdruck vom verwendeten Druckregler abhängt. Mit der erfindungsgemäßen Ventilvorrichtung ist es dagegen jederzeit möglich, die Gaszufuhr zu unterbrechen, wenn bestimmte Abschaltbedingungen vorliegen. Die Abschaltbedingungen können vorher individuell festgelegt und ggf. auch geändert werden.To achieve this object, a valve device for interrupting the gas supply of a supply line is proposed, which is characterized in that it comprises a valve which is controllable by means of an external signal, in particular an electrical signal. The invention is based on the finding that with a purely mechanically operating pressure regulator, the gas supply can be interrupted only in the presence of an overpressure in the gas supply line, wherein the limit value for the overpressure depends on the pressure regulator used. With the valve device according to the invention, however, it is always possible to interrupt the gas supply when certain shutdown conditions are present. The switch-off conditions can be set individually beforehand and possibly also changed.
Gemäß den bevorzugten Ausführungsformen der Erfindung ist das Ventil an einen Bus angeschlossen. Das Ventil kann ohne zusätzliche Energieversorgung durch die vom Bus bereitgestellte Energie geschaltet werden.According to the preferred embodiments of the invention, the valve is connected to a bus. The valve can be switched without additional power supply by the energy provided by the bus.
Vorzugsweise ist das Ventil ein bistabiles Ventil, insbesondere ein bistabiles 3/2-Wege-Ventil. Die Verwendung eines bistabilen Ventils hat den Vorteil, daß bei einem Stromausfall die Position des Ventils unverändert bleibt.Preferably, the valve is a bistable valve, in particular a bistable 3/2-way valve. The use of a bistable valve has the advantage that in the event of a power failure, the position of the valve remains unchanged.
Erfolgt die Unterbrechung der Gaszufuhr durch Absperrung einer Hauptzufuhrleitung ist hierfür in der Regel eine große Kraft notwendig. Deshalb sieht die Erfindung für diesen Fall einen in die Versorgungsleitung eingefügten Druckregler vor, wobei das Ventil an den Druckregler angeschlossen ist. Mit dem Druckregler kann der hohe Energieaufwand zum Schließen der Leitung bewerkstelligt werden, indem die vorhandene Überdruckabschaltung eines Gasdruckreglers genutzt wird. Die erfindungsgemäße Funktionalität (Sperren bei festgestelltem Bedarf) ist durch das extern steuerbare, an den Druckregler angeschlossene Ventil gewährleistet.If the interruption of the gas supply by blocking a main supply line this is usually a large force necessary. Therefore, the invention provides for this case, a pressure regulator inserted into the supply line, wherein the valve is connected to the pressure regulator. With the pressure regulator, the high energy consumption for closing the line can be accomplished by the existing overpressure shutdown of a gas pressure regulator is used. The functionality according to the invention (locking in case of a determined need) is ensured by the externally controllable, connected to the pressure regulator valve.
Gemäß einer Weiterbildung der Erfindung ist der Druckregler mit einer Unterdruckabschaltung ausgestattet, die durch die Ventilvorrichtung ausgelöst werden kann.According to one embodiment of the invention, the pressure regulator is equipped with a vacuum shut-off, which can be triggered by the valve device.
Bei Verwendung eines Druckreglers ist es zweckmäßig, einen ersten Anschluss (Eingang) des Ventils mit einer Zuleitung der Versorgungsleitung, einen zweiten Anschluss (Arbeitsanschluss) des Ventils mit einer Druckregelkammer des Druckreglers und einen dritten Anschluss (Entlüftung) des Ventils mit einem Ausgang des Druckreglers zu verbinden.When using a pressure regulator, it is convenient to a first port (input) of the valve with a supply line, a second port (working port) of the valve with a pressure control chamber of the pressure regulator and a third port (vent) of the valve with an output of the pressure regulator connect.
In einem ersten Schaltzustand (Normalzustand) können dann der zweite - Anschluss und der dritte Anschluss des Ventils und in einem zweiten Schaltzustand (Sperrzustand) der erste Anschluss und der zweite Anschluss des Ventils verbunden werden.In a first switching state (normal state), the second connection and the third connection of the valve and in a second switching state (blocking state) the first connection and the second connection of the valve can then be connected.
Alternativ kann vorgesehen sein, die Druckregelkammer des Druckreglers über das Ventil zu entlüften.Alternatively it can be provided to vent the pressure control chamber of the pressure regulator via the valve.
Gemäß einer anderen Ausführungsform ist das Ventil ein Vorsteuerventil zur Betätigung des Pneumatikventils, das über eine bewegliche Kolbenstange an einen Druckregler angekoppelt sein kann. Wenigstens das Pneumatikventil kann in den Druckregler integriert sein.According to another embodiment, the valve is a pilot valve for actuating the pneumatic valve, which may be coupled via a movable piston rod to a pressure regulator. At least the pneumatic valve can be integrated in the pressure regulator.
Das Pneumatikventil kann auch direkt in der Versorgungsleitung angebracht werden und dort die Unterbrechung der Gaszufuhr bewerkstelligen.The pneumatic valve can also be mounted directly in the supply line and manage the interruption of the gas supply.
Die Unterbrechung der Gaszufuhr kann aufgrund des extern steuerbaren Ventils nicht nur bei Vorliegen eines Überdrucks, sondern auch aufgrund anderer Umstände gesperrt werden. Beispielsweise kann das externe Signal von einem Sensor, insbesondere einem Gas- oder Rauchsensor, bereitgestellt werden.The interruption of the gas supply can be locked due to the externally controllable valve not only in the presence of an overpressure, but also due to other circumstances. For example, the external signal can be provided by a sensor, in particular a gas or smoke sensor.

In Figur 1 ist eine erste Ausführungsform der erfindungsgemäßen Ventilvorrichtung dargestellt. Die Vorrichtung umfasst einen in eine Gasversorgungsleitung eingefügten Druckregler 18 und ein an den Druckregler 18 angeschlossenes Schaltventil in Form eines bistabilen 3/2-Wege-Ventils 17.FIG. 1 shows a first embodiment of the valve device according to the invention. The device comprises a
Die Steuerung des Ventils 17 erfolgt über eine Elektronik. Gemäß der Darstellung in Figur 1 kann die Elektronik in eine Kontrolleinheit und eine über einen Bus mit dieser verbundenen Ventilelektronik aufgeteilt werden. Die vom Bus zur Verfügung gestellte Leistung ist auf 12 V und 1,5 mA (= 18 mW) begrenzt. Die Ventilelektronik ist in der Lage, diese Energie zu speichern. In Reaktion auf ein zusätzliches, externes Steuersignal, das in der Regel von der Kontrolleinheit ausgegeben wird, schaltet die Ventilelektronik das Ventil 17 unter Verwendung der zuvor gespeicherten Energie. Außer der Versorgung über den Bus wird hierfür keine zusätzliche Energieversorgung benötigt.The control of the
Der bei der Ausführungsform gemäß Figur 1 verwendete Druckregler 18 weist einen mit der Gaszuleitung verbundenen Eingang 4, einen Ausgang 5, eine Ventildichtung 6, einen Ventilsitz 7, einen Bypass 8, eine Spindel 9, eine Druckregelkammer 10, einen Teller 11 und eine Feder 12 auf.

Die Gaszuleitung ist ferner mit dem ersten Anschluss 1 (Eingang) des 3/2-Wege-Ventils 17 verbunden. Die Druckregelkammer 10 des Druckreglers 18 ist mit dem zweiten Anschluss 2 (Arbeitsanschluss) des Ventils 17 verbunden. Der Ausgang 5 des Druckreglers 18 ist mit dem dritten Anschluss 3 (Entlüftung) des 3/2-Wege-Ventils 17 verbunden.The gas supply line is further connected to the first port 1 (input) of the 3/2-
Im Normalzustand sind im 3/2-Wege-Ventil 17 die Anschlüsse 2 und 3 durchverbunden (erster stabiler Zustand). Der Bypass 8 zwischen dem Ausgang 5 und Druckregelkammer 10 des Druckreglers 18 ist verschlossen. Die erfindungsgemäße Vorrichtung erfüllt in diesem Zustand keine besondere Funktion und wirkt wie ein herkömmlicher, in die Gasversorgungsleitung eingefügter Druckregler.In the normal state, the
Wird das 3/2-Wege-Ventil 17 nun infolge eines externen Signals geschaltet (zweiter stabiler Zustand), so verbindet es die Anschlüsse 2 und 1. Damit wird der Versorgungsdruck in die Druckregelkammer 10 des Druckreglers 18 aufgeschaltet. Folglich wird der Teller 11 des Druckreglers 18 gegen die Feder 12 angehoben und schließt über die Spindel 9 den Ventilsitz 7. Dadurch ist die Gaszufuhr zum Verbraucher unterbrochen.If the 3/2-
Das Rückschalten des 3/2-Wege-Ventils 17 erfolgt auf die gleiche Weise, d. h. wiederum in Reaktion auf ein externes Signal und mit Hilfe der aus dem Bus entnommenen Energie. Dies ist möglich, da es sich um ein bistabiles Ventil handelt. Nach dem Rückschalten befindet sich der Druckregler 18 wieder im Normalzustand.The switching back of the 3/2-
Alternativ zu dieser Lösung kann die Druckregelkammer 10 des Druckreglers 18 über das bistabile 3/2-Wege-Ventil 17 entlüftet werden, um den Teller 11 durch die Kraft der Feder 12 abzusenken und den Ventilsitz 7 freizugeben. Gleichzeitig wird der Bypass 8 verschlossen.Alternatively to this solution, the
Eine zweite Ausführungsform der Erfindung ist in Figur 2 dargestellt. Die Ventilvorrichtung umfasst hier ein Pneumatikventil 15, ein Vorsteuerventil 17 und einen Druckregler 18, der ähnlich wie bei der zuvor beschriebenen ersten Ausführungsform aufgebaut ist. Das Pneumatikventil 15 ist über eine bewegliche Kolbenstange 16 mit Dichtungshalter 14 an den Eingang 4 des Druckreglers 18 angekoppelt. Zumindest das Pneumatikventil 15 kann teilweise oder vollständig in den Druckregler 18 integriert sein.A second embodiment of the invention is shown in FIG. The valve device here comprises a
Die elektronische Steuerung der Ventilvorrichtung erfolgt wie bei der ersten Ausführungsform. Geschaltet wird hier das Vorsteuerventil 17, das als bistabiles 3/2-Wege-Ventil ausgebildet ist. Die Energie für den Schaltvorgang wird dem Bus entnommen, ohne dass eine zusätzliche Spannungsversorgung nötig ist.The electronic control of the valve device is carried out as in the first embodiment. Switched here is the
Im Normalzustand ist das Pneumatikventil 15 geöffnet, so dass der Gasstrom zum Verbraucher nicht unterbrochen ist. Durch Schalten des Vorsteuerventils 17 wird der Versorgungsdruck, der am Eingang 4 des Druckreglers 18 ansteht, auf das Pneumatikventil 15 gegeben. Durch die Betätigung des Pneumatikventils 15 wird dann im Druckregler 18 die Gaszufuhr zum Verbraucher unterbrochen.In the normal state, the
Der maximale Hub des Pneumatikventils 15 muss im geöffneten Zustand (Normalzustand) so groß sein, dass der Durchfluss im Druckregler 18 gar nicht oder nur geringfügig beeinträchtigt wird.The maximum stroke of the
In Figur 3 ist eine dritte Ausführungsform der Erfindung gezeigt, die der zuvor beschriebenen zweiten Ausführungsform sehr ähnlich ist, bei der jedoch kein Druckregler zum Einsatz kommt. Hier ist die Vorrichtung mit dem Vorsteuerventil 17 und dem Pneumatikventil 15 direkt an der Versorgungsleitung angebracht. Nach dem Schalten des Vorsteuerventils 17 sorgt das Pneumatikventil 15 selbst für die Unterbrechung der Gaszufuhr.FIG. 3 shows a third embodiment of the invention, which is very similar to the previously described second embodiment, but in which no pressure regulator is used. Here, the device with the
In Figur 4 ist eine vierte Ausführungsform dargestellt, die auf der ersten Ausführungsform basiert. Der Gasdruckregler 18 ist hier etwas anders aufgebaut und zusätzlich mit einer Unterdruckabschaltung ausgestattet. Bei einem Druckabfall in der Verbraucherleitung, der beispielsweise im Falle einer Leckage (Leitungsbruch, versehentlich offene Verbrauchsstelle u.ä.) auftritt, schaltet der Druckregler 18 die Gaszufuhr automatisch ab.FIG. 4 shows a fourth embodiment based on the first embodiment. The
