Compared with the common valve which is only in an open state and a closed state, the high-pressure fluid discharge system can control the flow and the pressure of compressed air by additionally arranging the one-way throttle valve 6, so that the discharge speed of the system is controllable, and the noise pollution caused by overhigh discharge speed is avoided.

The filtering and pressure regulating valve 4 provides clean compressed air for the air pipe, and the pressure of the compressed air can be automatically regulated when the pressure fluctuates, so that the pressure is stably output, and the pressure stability is ensured.

Air buffer tube 5 is used to reduce flow and pressure non-uniformities in the tube and avoid flow and pressure fluctuations to accommodate process flow requirements air inlet 7 of air buffer tube 5 is used for inlet air, outlet 8 is used for outlet air, outlet 9 is used for drain, valve is located at outlet 9, valve is open when drain is required and valve is closed otherwise.

The check throttle 6 is a valve for controlling the flow of fluid by changing the throttle section or the throttle length, and a parallel connection of a throttle valve and a check valve can be combined into a check throttle, which is a simple flow control valve.

The pneumatic bleed valve 3 is powered by compressed air to trigger the opening and closing of the valve.
