摘要
介绍了换向阀的主要性能要求、工作原理和中位机能,并以几种典型换向阀为例,介绍了它们的中位机能、结构特点以及机能特点,同时举例说明了在采煤机的液压系统中,几种典型换向阀中位机能所发挥的重要作用。
Introduces the main performance demand, working principle and median function of the directional control valve, and introduces the median function and its structure and function characteristics of several typical directional control valve. At the same time, it illustrates the important role that the median function of the directional control valve acts in the liquid pressure system of coal cutting machine.
