摘　　要：介绍传统燃气比例阀和零压阀的控制原理。以VGU82燃气比例阀为例,探讨该燃气比例阀的结构和功能及工作原理,分析了该燃气比例阀在稳定出口压力和维持恒定空燃比的工作过程。The control principles of traditional gas proportional valve and zero pressure valve are intro- duced. VGU82 gas proportional valve is taken for ex- ample to discuss the structure, functions and working principle of gas proportional valve. The working process of gas proportional valve under stable outlet pressure and constant air/gas ratio is analyzed.
