Beschreibung
Zusammenfassung:	The invention discloses a structural design method of a hydraulic direction control valve. The structural design method comprises the steps of pilot valve structural design, main valve element and main valve seat structural design and automatic reset function design. The pilot valve structure, the main valve element and main valve seat structure and the automatic reset function of the hydraulic directional control valve are designed, various specific parameters of the hydraulic directional control valve under the good working condition are obtained, and it is ensured that the hydraulic directional control valve meets the working requirements of an underwater Christmas tree. 本发明公开了一种液压方向控制阀的结构设计方法，包括先导阀结构设计、主阀芯与主阀座结构设计、自动复位功能设计。本发明通过对液压方向控制阀的先导阀结构、主阀芯与主阀座结构、自动复位功能进行设计，得到了液压方向控制阀良好工况下的各项具体参数，确保液压方向换向阀满足水下采油树的工作需求。
