Abstract

Die Erfindung betrifft eine Vorrichtung (10) mit einem Gasventil (14) zur Beeinflussung der Durchflussmenge eines Gases (G) durch eine Brennstoffzufuhrleitung (11) zu einem Brenner (13). Das Gasventil (14) weist ein erstes Ventil (24) und ein zweites Ventil (40) auf. Beide Ventile (24), (40) sind als Doppelsitzventile mit jeweils zwei Ventilgliedern (26), (27) bzw. (42, 43) ausgestaltet. Jedes Ventil (24, 40) weist einen elektromagnetischen Ventilantrieb (52, 53) auf. Über eine Steuereinrichtung (54) sind die beiden Ventilantriebe (52, 53) unabhängig voneinander ansteuerbar. Ein Drucksensor (60) erfasst einen Druck (p) stromabwärts des ersten Ventils (24). Mit Hilfe des ersten Ventils (24) führt die Steuereinrichtung (54) eine Druckregelung an der Druckmessstelle durch. Das dem ersten Ventil (24) in Strömungsrichtung des Gases (G) nachgeschaltete zweite Ventil (40) kann als Drossel verwendet werden. Abhängig von der angeforderten Brennerleistung kann der Volumenstrom oder der Massenstrom des Gases (G) durch die Brennstoffzufuhrleitung (11) über das zweite Ventil (40) durch Ansteuerung des Ventilantriebs (53) durch die Steuereinrichtung (54) eingestellt werden.

The invention relates to a device (10) with a gas valve (14) for influencing the flow rate of a gas (G) through a fuel supply line (11) to a burner (13). The gas valve (14) has a first valve (24) and a second valve (40). Both valves (24), (40) are designed as double-seat valves, each with two valve members (26), (27) and (42, 43). Each valve (24, 40) has an electromagnetic valve drive (52, 53). Via a control device (54), the two valve actuators (52, 53) are independently controllable. A pressure sensor (60) detects a pressure (p) downstream of the first valve (24). With the aid of the first valve (24), the control device (54) performs pressure regulation at the pressure measuring point. The first valve (24) in the flow direction of the gas (G) downstream second valve (40) can be used as a throttle. Depending on the requested burner capacity, the volume flow or mass flow of the gas (G) through the fuel supply line (11) via the second valve (40) by controlling the valve drive (53) by the control device (54) can be adjusted.
