초록 ▼

A fuel metering valve for a gas turbine active combustion control system has a highly responsive pressure balanced valve assembly with either a flapper or clevis member. The valve member is mounted at one end to an armature of a magnetic drive assembly and a movable part of a flexure pivot otherwise fixed to the valve housing. The armature, flexure pivot and valve member are disposed along a main axis. Magnetic flux selectively pulls the armature toward opposite sides of the main axis causing it and the valve member to pivot in the flexure pivot such that an end of the valve member moves toward or away from an orifice in a nozzle passageway to control metering. The flapper is preferably balanced by a diaphragm piston biasing it in the direction of the nozzle passageway. The alternative clevis arrangement is inherently balanced and can meter fuel through multiple nozzle orifices simultaneously.

1. A fuel metering valve capable of operating in an active combustion control system of a gas turbine, the valve comprising:a valve housing having an inlet port and an outlet port; a nozzle passageway disposed between the inlet and outlet port; a drive assembly disposed in the valve housing and having a movable actuator member disposed along a main axis; a flexure pivot mounted to the housing and the actuator member to allow pivoting of the actuator member with respect to the main axis; and a valve member mounted to be disposed along the main axis and to pivot about the flexure pivot with the actuator member to control flow through the nozzle passageway; wherein the valve member is a clevis having a stem mounted to the actuator member and a forked end defining two prongs located to interrupt flow through a pair of nozzle orifices leading from the nozzle passageway. 2. The valve of claim 1, wherein the actuator and valve member move in proportion to an input current to the drive assembly.3. The valve of claim 1, wherein the flexure pivot has a movable part and a non-moving part in a plane spaced from the movable part and joined thereto by a flexible spoke.4. The valve of claim 1, wherein the drive assembly includes a permanent magnet and an electromagnet including a wire coil disposed about a movable armature actuator member.5. The valve of claim 4, wherein the armature is selectively pulled by magnetic flux toward opposite sides of the main axis causing the valve member to pivot with respect to the main axis and move with respect to the nozzle passageway.6. The valve of claim 1, wherein the valve member is pressure balanced.7. The valve of claim 1, wherein the nozzle orifices are slots formed in a valve sleeve defining the nozzle passageway disposed in the valve housing.8. The valve of claim 7, wherein each of the prongs has an elongated tapered leading edge.9. The valve of claim 8, wherein a bridge is mounted between the two prongs of the clevis.10. The valve of claim 9, wherein the valve sleeve defines two pairs of spaced apart nozzle orifices and each prong of the clevis member defines two legs spaced apart in registration with the outlet orifices, such that pivoting of the clevis member moves each leg of the clevis member the same distance with respect to its associated nozzle orifice.11. The valve of claim 10, wherein the nozzle orifices are formed in opposite walls of a section of the valve sleeve having a rectilinear outer periphery disposed between the prongs of the clevis and the bridge.12. A fuel metering valve capable of operating in an active combustion control system of a gas turbine, the valve comprising:a valve housing having an inlet port and an outlet port; a nozzle passageway disposed between the inlet and outlet port; a magnetic drive assembly disposed in the valve housing and having an armature disposed along a main axis and selectively pulled toward opposite sides of the main axis; a flexure pivot disposed about the main axis and having a movable part mounted to the armature and a non-moving part fixed to the housing to allow pivoting of the actuator member with respect to the main axis; and a clevis member mounted to the armature and the movable part of the flexure pivot at one end and having a forked end defining two prongs symmetrical about the main axis and each adapted to control flow through an associated orifice of the nozzle passageway when the clevis is pivoted about the flexure pivot in response to movement of the armature.
