Pressure governor valve is the use of a spring-loaded power and pressure balance theory, when the spring-loaded pressure less than atmospheric pressure and the valves closed when the pressure is greater than the spring-loaded rubber tubing stretch when the bottom of compressed air diaphragm, diaphragmthe effort to promote diaphragm upward and left vavle seat blow the air flow of gas, this would piston shirking role in the pressure mobile, Selection will be emissions from valve seat, air compressors made by the then air into the gas valves and exhaust emissions is through the mouth into atmospheric

调压阀的原理是利用了弹簧力与压力相平衡的原理，当弹簧的压力小于气压的时候阀关闭，当压力大于弹簧的弹力时候橡胶调压膜片下方的压缩空气对膜片的作用力，推动膜片向上拱曲离开阀座而使空气流入气腔，此时卸荷活塞在气压作用下移动，将排放阀门推离阀座，于是由空气压缩机充入气腔的空气便通过排放阀和排气口排入大气空气压缩机空转。
