摘要
溢流阀、减压阀、顺序阀是液压系统中关键的压力控制元件,其图形符号外观相似,但不尽相同。结合三种压力阀的基本结构和工作原理深入解读了其图形符号,重点对三种压力阀图形符号的异同进行了比较分析,以便在理解记忆的基础上能正确绘制和识读三种压力阀的图形符号。
The relief valve, pressure reducing valve and sequence valve are the key control elements in whole hydraulic transmission system. The appearance of their graphical symbols are similar, but not the same. The article focuses on the similarities and differences between the graphic symbols of three kinds pressure valve based on their structure and working principle, so that draw and read graphical symbols of pressure valve more easily on the basis of understanding memory.
