导弹发射井盖启闭液压系统
Cover opening and closing hydraulic system in missile launching silo.

　　该液压系统大量采用插装阀组结构，并由传感器进行运动工况的实时检测，经PLC进行判断和控制处理，依靠PLC强大的指令系统来实现过程监控、报警处理等功能，使导弹发射井盖能准确可靠的实现规定动作。
　　Utilizing a number of plug-in valve groups, this hydraulic system can implement real-time monitoring over working condition by transducers and exercise judgment and handling by way of PLC whose powerful command system can ensure process monitoring and alarm handling, thus making the missile launching slot cover act as required in an accurate and reliable way.
