Abstract
The invention discloses a constant pressure discharge system. The constant pressure discharge system comprises a driving air port, a first adjusting valve, a second adjusting valve, a Venturi tube, adischarge outlet and an instrument outlet; the driving air port, the second adjusting valve, the Venturi tube and the discharge outlet sequentially communicate, the driving air port communicates withan air source of high-pressure driving air, the second adjusting valve is in signal connection with the discharge outlet, the instrument outlet communicates with a throat tube of the Venturi tube, oneend of the first adjusting valve is arranged between the driving air port and the second adjusting valve in a communication manner, the other end of the first adjusting valve is arranged between theinstrument outlet and the throat tube of the Venturi tube in a communication manner, and the first adjusting valve is in signal connection with the instrument outlet. Backpressure of an instrument canbe stabilized within the preset numerical value, the measuring accuracy is greatly improved, the structure is simple, and the use is convenient.
