Zusammenfassung:The utility model discloses a quick adjusting system used for improving adjusting ability of a thermal power generating unit. The adjusting system comprises a quick adjusting valve, an electro-hydraulic converter, a check valve, a hydraulic servo-motor, a stop valve and a filter element. High pressure oil supply is connected with an oil inlet of the electro-hydraulic converter through the stop valve and the filter element. An oil control port of the electro-hydraulic converter is connected with an oil control port of the quick adjusting valve and a lower cavity of the hydraulic servo-motor. An oil return port of the electro-hydraulic converter, an upper cavity of the hydraulic servo-motor, an oil return port of the quick adjusting valve, the check valve and an oil tank are connected in sequence. A turbine electro-hydraulic control system based on the novel quick adjusting valve is capable of improving the quick adjusting ability of a turbine generator unit effectively.
