Description

Technical Field

[0001] The utility model specifically relates to the technical field of valve blocks, in particular to a hydraulic valve block with a long service life. Background Art

[0002] Valve block, electro-hydraulic servo control system, is one of the eight systems in TRT device. According to the instructions of the main control room, it realizes the system control of TRT, such as start, stop, speed control, power control, furnace top pressure and process detection. To realize the functional control of the above systems, it 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 accuracy and error of the control system directly affect the control of each stage of the TRT system. It can be seen that the status and role of this system in TRT are very important.
