Description
technical field [0001] The invention relates to the field of fuel supply systems for gas turbines, in particular to a fuel supply control valve. In addition, the present invention also relates to a fuel supply system comprising the above-mentioned fuel supply control valve. Background technique [0002] figure 1 It is a schematic diagram of a general gas turbine fuel supply system, which includes a coarse fuel filter, a low-pressure pump, a fine fuel filter, a fuel regulator, a fuel supply control valve, and nozzles. The fuel supply control valve is an important part of the fuel supply system, which is responsible for the opening and closing of the fuel supply required for the gas turbine, and then controls the start and stop of the gas turbine. [0003] At present, the structure of the more widely used fuel supply control valve is as follows: figure 2 As shown, it is an electromagnetically controlled electromagnetic valve, which mainly includes an electromagnetic coil, ...
