Abstract：
 The invention relates to a non-powered mechanical feedback gas feeding amount automatic adjusting valve. Wherein, the pressure reducer is connected to the flux adjuster via the spring-dual-film device the valve is sealed with a pressure reducer, the flux adjuster and the spring-dual-film device. The valve high-pressure chamber is divided into two channels, while one is connected to the hand bypass gas feeding adjusting valve, and another one is connected to the switch of pressure reducer. Said adjusting valve has simple structure, flexible motion and better sealing property, while its initial flux can be set. When the initial flux has been set, the flux will be automatically lined adjusted via the outlet pressure. And the invention can apply liquid flux adjustment.
