三种压力阀的异同之辨析

Analysis on the Similarities and Differences of Three Kinds of Pressure Valves

压力控制阀是液压系统中重要的控制元件,作为压力控制阀的三种主要元件:溢流阀、减压阀、顺序阀,从其工作原理、性能结构、外形差异、不同的功能以及在工程实际中的选择和调节等方面分析归纳,对三种压力阀的异同之处进行研究辨析。为学生学习本课程和以后在实际工作中提供重要的参考依据。

Pressure control valve is an important control component in hydraulic system. This paper analyzes the work- ing principle, function structure, shape differences, different functions and selection and adjustment of overflow valve, relief valve, sequence valve, as the three main components of pressure control valves. And this paper also an- alyzes the similarities and differences of three kinds of pressure valves, providing important reference for students to learn this course and in the practical work.
