Introduction of HYZ-4 Isolated Oxygen Breathing Apparatus

HYZ-4 Isolated Positive Pressure Oxygen Breathing Apparatus with low-pressure gas inside the balloon passes through the suction cooling device, suction tube, suction valve into the mask, and the exhaled gas of people passes through the mask exhalation valve, breath control, clean tank to the balloon; when the exhaled gas gradually increases, pressure spring is compressed. Meanwhile, the spring platen position gradually increased. When the internal pressure reaches the respiratory system (400 ~ 700) Pa, the exhaust valve spring plate valve is open the top. At this point, the exhaust valve exhaust begins; when the person's breathing capacity from (10 ~ 50) L / min range changes, the breath pressure is always a demand valve, exhaust valve automatically adjusts both.
