HYZ-4 Positive Pressure Oxygen Respirator
Application&Introduction
In the air bag lowpressure gas through the suction cooling device, a suction pipe, a suction valve to the mask, people in the mask exhaled gas through the exhalation valve, the expiratory tube, cleaning tank to the air bag; when the exhaled gas increases gradually and positive pressure spring is compressed. At the same time, the position of the spring pressure plate is gradually rising. When the pressure in the respiratory system to reach (400~700) Pa, the exhaust valve plate is pushed by the spring pressure plate. At this point, the exhaust valve to start the exhaust; when people's breath from (10~50) L/min range of changes, the breathing is always by the demand valve, exhaust valve automatic adjustment
