溢流阀、减压阀和顺序阀在许多方面很相似，容易混淆。本文从工作原理，压力判定和用途等方面作一些阐述，力求使三者之间更易区别。
There are many similarities among the overflow valve,the decompression valve and the order valve,so they are easily confused.This article expounds their structure theory,determination of pressure and use.The writer strives to help users to distinguish those valves easily.
