Pressure regulating valve is a key equipment for flow field regulation in wind tunnels. Based on the special pressure regulation characteristics of 1m level half-closed layout blowdown Intermittent wind tunnel and wind tunnel performance indicators, the design and development of pressure regulating valves are carried out. A detailed study was conducted
