煤矿单体支柱用纯水三用阀的研究

Study on Water Three Way Valve Used in Coal Mine Hydraulic Prop

在充分考虑水介质特殊的理化性能的基础上,介绍了纯水液压阀的关键技术问题和三用阀的工作原理,并从材料、密封形式、新型结构等方面入手,提出了相应的解决措施。指出了以高水基乳化液为工作介质的单体支柱存在的严重环境污染问题,介绍了纯水液压传动的优点,在设计制造及材质选择方面对纯水三用阀进行了研究。

Considered some physical and chemical characteristics of water sufficiently, key technical problems of water valve and working principle of three way valve are introduced and solved from aspects such as material, seal form, new structures. Shows the serious environmental pollution problems in mine prop with emulsion, introduces the advantages of the hydraulic system with water medium. In the end, it studies on the design, production technology and material selection of water three way valve.
