This equipment can calibrate various flanged breathing valves and is a special device for calibrating breathing valves. It is suitable for checking the positive pressure exhalation, negative pressure inhalation opening pressure and sealing performance of the breathing valve. It uses vacuum negative pressure to detect the inhalation opening pressure of the breathing valve and uses the external positive pressure to detect the exhalation opening pressure of the breathing valve, so as to detect whether the inhalation and exhalation pressure values of the breathing valve meet the set requirements, and air tightness test can be carried out at the same time.
