The valve block is used in the electro-hydraulic servo control system. In the TRT device, it is a sub-system of one of the eight major systems.
The electro-hydraulic servo control system is a sub-system of one of the eight major systems in the TRT device. According to the instructions of the main control room, the system control of TRT start, stop, speed control, power control, furnace top pressure and process detection is realized. To realize the function control of the above system, it will be reflected in the speed of the control turbine. , It is necessary to control the opening of the transparent vane, and the method of controlling the opening of the vane is the electro-hydraulic position servo system. The accuracy and error of the control system directly affect the control of the various stages of the TRT system. It can be seen that the status and role of the system in TRT are very important
