Function of valve block system

       Electro hydraulic servo control system, in TRT device, belongs to one of the eight systems. According to the command of the main control room, to realize the TRT start, stop, speed control, power control, furnace top pressure and process detection system control, to realize the above system function control, will eventually be reflected in the control of turbine speed, it is necessary to control the opening of the turbine stator, and the means of controlling the opening of the stator is the electro-hydraulic position servo system. The precision and error of the control system directly affect the process control of TRT system. It can be seen that the system plays an important role in TRT.
