摘要
从液压支架三位四通电液换向阀的结构和工作原理展开研究,对电液换向阀的核心部件进行受力分析。通过研究换向阀的受力、流场情况,及阀体内对中弹簧的影响,分析电液换向阀的动态特性。
The structure and working principle of the three-way electro-hydraulic reversing valve of the hydraulic support are studied, and the core components of the electro-hydraulic reversing valve are analysed in terms of force. The dynamic characteristics of the electro-hydraulic reversing valve are analysed by studying the force on the reversing valve, the flow field situation, and the influence of the spring in the valve body.
