Description
Die Erfindung betrifft eine Regeleinrichtung für Gasbrenner nach dem Oberbegriff des Anspruchs 1.The invention relates to a control device for gas burners according to the preamble of claim 1.
Aus der
Aus der
Unter regulären Betriebsbedingungen herrscht in der Gasleitung, mithilfe derer Gasstrom der Mischeinrichtung zugeführt wird, ein Druck, der geringer ist als der Referenzdruck. In diesem Fall besteht keine Gefahr, dass über den elektrischen bzw. elektronischen Sensor, der typischerweise als Durchflussmesser bzw. als Anemometer ausgeführt ist, Gas aus der Gasleitung in Richtung auf den Referenzpunkt des Sensors entweicht. Dann jedoch, wenn in der Gasleitung Druckschwankungen auftreten, kann sich die Situation einstellen, dass der Druck der zur Mischeinrichtung führenden Gasleitung größer wird als der Referenzdruck, wobei dann über den Sensor, der mit einem Messpunkt an der Gasleitung und mit einem Referenzpunkt am Referenzdruck angreift, Gas aus der Gasleitung in Richtung auf dem Referenzpunkt gesaugt wird. Da es sich beim Referenzdruck vorzugsweise um den Umgebungsdruck handelt, gelangt dann Gas über den als Durchflussmesser bzw. Anemometer ausgebildeten Sensor von der Gasleitung in die Umgebung. Die unter solchen Umständen gegebenenfalls über den Sensor in die Umgebung gelangende Gasmenge ist so gering, dass sie sicherheitsunkritisch ist. Die Gasmenge kann jedoch mit einem Gassensor detektiert werden, sodass dann, wenn ein Installateur an einer solchen Regeleinrichtung einen Gassensor einsetzt, für den Installateur der fehlerhafte Eindruck entstehen kann, über die Regeleinrichtung würde eine sicherheitskritische Gasmenge in die Umgebung entweichen. Dies kann unnötige Servicearbeiten an der Regeleinrichtung verursachen.Under normal operating conditions, in the gas line, by means of which gas flow is supplied to the mixing device, there is a pressure which is lower than the reference pressure. In this case, there is no danger that escapes via the electrical or electronic sensor, which is typically designed as a flow meter or anemometer, gas from the gas line in the direction of the reference point of the sensor. Then, however, when pressure fluctuations occur in the gas line, the situation may arise that the pressure of the gas line leading to the mixing device is greater than the reference pressure, in which case via the sensor, which acts with a measuring point on the gas line and with a reference point at the reference pressure , Gas is sucked from the gas line in the direction of the reference point. Since the reference pressure is preferably the ambient pressure, gas then passes from the gas line into the environment via the sensor designed as a flowmeter or anemometer. The amount of gas that possibly enters the environment via the sensor in such circumstances is so low that it is not safety-critical. However, the amount of gas can be detected with a gas sensor, so that when an installer on such a control device uses a gas sensor, for the installer may cause the erroneous impression, via the control device would escape a safety-critical amount of gas into the environment. This can cause unnecessary service to the controller.
Hiervon ausgehend liegt der Erfindung das Problem zu Grunde, eine neuartige Regeleinrichtung für Gasbrenner zu schaffen. Dieses Problem wird durch eine Regeleinrichtung für Gasbrenner mit den Merkmalen des Anspruchs 1 gelöst. Erfindungsgemäß ist die Mischeinrichtung als Venturi-Düse ausgebildet, wobei die Gasleitung in einen Mischbereich der Venturi-Düse mündet, in welchem der Gasstrom und der Verbrennungsluftstrom zum Gas-/Luft-Gemisch gemischt werden, wobei der Referenzpunkt des Sensors an einer Einrichtung angreift, in welcher der Referenzdruck herrscht, und wobei die Einrichtung über eine Kopplungsleitung mit der Venturi-Düse verbunden ist, nämlich mit einem Bereich der Venturi-Düse, der in Strömungsrichtung des Gas-/Luft-Gemischs gesehen stromabwärts des Mischbereichs derselben liegt.On this basis, the invention is based on the problem of creating a novel control device for gas burners. This problem is solved by a control device for gas burner with the features of claim 1. According to the invention, the mixing device is designed as a Venturi nozzle, wherein the gas line opens into a mixing region of the Venturi nozzle, in which the gas stream and the combustion air stream are mixed to the gas / air mixture, wherein the reference point of the sensor acts on a device which the reference pressure prevails, and wherein the device is connected via a coupling line with the Venturi nozzle, namely with a region of the Venturi nozzle, which, seen in the flow direction of the gas / air mixture downstream of the mixing region thereof.

In diesem Fall kann dann keinerlei Gas in die Umgebung gelangen, welches von einem Gassensor detektiert werden könnte. Auf diese Art und Weise können unnötige Wartungsarbeiten an voll funktionsfähigen Regeleinrichtungen vermieden werden.By means of the coupling line via which the device to which the reference pressure of the sensor engages is connected to the Venturi nozzle, it can be ensured that any gas passing through the sensor to the reference point of the sensor, possibly due to pressure fluctuations in the gas line, enters the venturi. Nozzle is conveyed. In this case, then no gas can enter the environment, which could be detected by a gas sensor. In this way, unnecessary maintenance on fully functional control devices can be avoided.

Die Untergliederung der Einrichtung in zwei Kammern, nämlich in die innere Kammer und die äußere Kammer, verfügt über den Vorteil, dass keine Gefahr besteht, dass Verunreinigungen aus der Umgebungsatmosphäre in den Bereich des als Durchflussmesser bzw. Anemometer ausgebildeten, elektrischen bzw. elektronischen Sensors gelangen können.The subdivision of the device into two chambers, namely in the inner chamber and the outer chamber, has the advantage that there is no danger that contaminants from the ambient atmosphere in the range of designed as a flow meter or anemometer, electrical or electronic sensor can.
