四、液压控制机构——阀介绍液压传动系统中各种控制阀的结构原理、性能与用途。液压控制阀的作用是通过控制液压系统中液体的流动方向、压力和流量,实现对机器的液压执行机构的各种控制,如滑块的起动和停止、运动的方向、压力和速度、以及工作的顺序等等。阀的种类和结构很多,一般均按其控制对象把它划分为三大类。
Fourth, the hydraulic control mechanism - Valve Introduction Hydraulic transmission system in a variety of control valve structure principle, performance and purpose. The function of the hydraulic control valve is to control the hydraulic actuator of the machine by controlling the flow direction, pressure and flow of the liquid in the hydraulic system, such as starting and stopping of the slider, direction of movement, pressure and speed, and work The order and so on. Valve type and structure of many, generally according to their control object it is divided into three categories.
