Detailed Description
HYZ-2 Isolation type positive pressure oxygen respirator
Safe
reliable
comfortable and easy to operate
Product Features：
HYZ2 type isolated positive pressure oxygen breathing apparatus is mine rescue team members in the rescue work for personal respiratory protection devices. For mine rescue team members when they are engaged in rescue work respiratory protection to protect them from poisonous gas damage. A safe, reliable , comfortable , easy operation and so on.
Working principle:
1, when open the oxygen tanks, high pressure gas by pressure reducer into medium pressure gas. Medium pressure gas all the way through the demand valve, and the other all the way through quantitative gas hole into the low pressure in the system. When the body is medium intensity of labor, through quantitative oxygen supply to meet human demand for oxygen. With the increase of the human body the intensity of labor, when the pressure in the air to demand open valve, the valve spring clamp contact demand, demand valve open, the medium pressure gas inside air oxygen filling via the demand valve to meet human demand for oxygen. Positive pressure formation in the system, it is depend on the spring clamp compressed air bags and the oxygen to the effective demand, had always maintain positive pressure in the respiratory system.
2, airbags within the low pressure gas by suction cooling device, the suction, suction valve to the mask, man in a mask breath exhale through the exhalation valve, pipe, clean tank to the airbag; When the exhaled gas increase gradually, positive pressure spring is compressed. At the same time, the spring clamp position gradually rise. When the pressure in the respiratory system is reached (400 ~ 700) Pa, when the exhaust valve valve plates are open spring clamp. At this point, the exhaust valve to vent; When people breathe the amount from the L/min (10 to 50) changes, the scope of respiratory pressure always by demand valve, exhaust valve both automatic adjustment.
