摘　　要：水介质阀控充液式液力偶合器作为刮板输送机上的动力传输及保护设备,保障了整个系统的稳定运行,而电液阀作为偶合器的控制元件,其性能的优劣对偶合器乃至整个系统的稳定都起到了至关重要地作用。通过介绍该类偶合器系统的工作原理,重点分析了电液阀应用中的一些常见问题,并提出了一些应对措施。As the power transmission and protection equipment of the scraper conveyor, the water valve-controlled fluid coupling ensures the systematic steady operation. And for the electro-hydraulic valve is taken as the control element of the coupling, its properties play a very important role in stabilities of the coupling and the whole system. This paper introduces the working principle of the coupling briefly, emphatically analyzes the common application problems of the electro-hydraulic valve, and puts forward some solutions.
