摘　　要：论述了自力式压差控制阀在使用中出现的不当安装和使用现象。分析了自力式压差控制阀3种不同结构型式的结构特点、工作原理及其内部结构与安装位置的差别。指出了直通式自力式压差控制阀主要应用于末端自主调节变流量的供热系统中,而压差旁通阀主要应用于供热和供冷系统中供回水旁路上的正确使用方法。This paper discusses the improper installation and use of self-operated differential pressure control valve,analyzes the structural characteristics and working principles of three different types of self-operated differential pressure control valves as well as the differences between their internal structures and installation positions. Straight-through self-operated differential pressure control valve is mainly used in variable-volume heat supply system with self-adjusting terminal,and pressure bypass valve is mainly used in the bypass of water supply and return system in heating and cooling system. The proper operation methods of the valves are pointed out.
