Aiming at the problem of the exhaust air pressure delay of the quick release valve of the commercial vehicle pneumatic braking system,the quick release valve is optimized to reduce the delay air pressure and time.The system simulation software AMESim is used to simulate the quick release valve to obtain the variables that have a greater impact on the exhaust delay.The orthogonal test method is used to study the quick release valve diaphragm thickness,exhaust port flow area,and exhaust port air gap width.The effect of the valve exhaust delay.In the optimal structure,the air gap width of the qui...
