    • A hydraulic control device for controlling a turbine valve is disclosed. The hydraulic control device includes a hydraulic pressure generating unit (1), a hydraulic pressure control unit (2), a hydraulic pressure actuating unit (3) and hydraulic attachments. The hydraulic pressure generating unit has an oil tank (12), an oil cooler (14) and a variable delivery type hydraulic pump (10). The hydraulic pressure control unit has a safety valve (20) and a servo valve (24). The hydraulic pressure actuating unit has a servo cylinder (30) and accumulators (32). The hydraulic attachments have a pressure reducing valve (40) and dump valves (42) and (43). Unlike the conventional control device, the present invention has a relatively simple structure. In addition, the pressure in a system can be maintained in a stable condition, and accuracy in controlling the turbine valve is increased, thus enhancing the quality of electricity supply created by a turbine.
    • 公开了一种用于控制涡轮阀的液压控制装置。 液压控制装置包括液压发生单元(1),液压控制单元(2),液压致动单元(3)和液压附件。 液压发生单元具有油箱(12),油冷却器(14)和可变输送型液压泵(10)。 液压控制单元具有安全阀(20)和伺服阀(24)。 液压致动单元具有伺服缸(30)和蓄能器(32)。 液压附件具有减压阀(40)和排放阀(42)和(43)。 与传统的控制装置不同,本发明具有相对简单的结构。 此外,系统中的压力可以保持在稳定的状态,并且提高了控制涡轮阀的精度,从而提高了涡轮机产生的电力供应质量。
