As shown in the figure! I don’t know what principle this little thing operates on; I hope someone experienced can give me some advice! Thank you!
The compressor anti-surge control valve is used in this device to enable the control valve to open quickly and close slowly.
The one below is a check valve; the one above is an adjustable flow control valve – an adjustable flow control valve that allows one-way flow
Newcomers, come and take a look, learn*learn*!
Throttle valves with check valves are commonly used for preventing surging in compressors and for regulating compression hydraulic couplings.
