Product Name: insulated compressed oxygen self-rescuer 

 Product Model: ZY45 type 

 Coal safety sign: MFA070044 

 Description: 
 The product is the use of compressed oxygen for the isolation of the gas source closed loop personal respiratory protection devices, mainly used in the work environment in the air toxic and harmful gas pollution and hypoxia, for the wearer to provide clean oxygen. 

 Product characteristics and uses: 
 1, use: 
 ZY45 compressed oxygen self a compressed oxygen gas source, isolated from the closed loop personal respiratory protection. Mainly used in coal mines or ambient air toxic and harmful gas pollution and hypoxia asphyxia disasters, site personnel quickly wear protection of normal breathing to flee the disaster area. 
 2, features: 
 , the use of the breathing patterns of the two-loop cycle, ie, breathing each for one-way channel, compared reciprocating breathing, its advantage is that the resistance is small, no dust inhalation, choking, the suction temperature is low, comfortable, safe and reliable. 
 b, with three oxygen: quantitative oxygen, automatic supply of oxygen and manual supply oxygen. Greatly improve the safety and reliability of respiratory protection. 
 c, filled with oxygen, the replacement of absorbent, maintenance and repair easy. 
 d, protective long time, easy to self-help. 
 e, small size, light weight, easy to carry. 
 f, can be used repeatedly, the use of low cost. 
 g, pressure indicators observed to pass, easy to use. 

 How it works: 
 The use of the self-rescuer, the counterclockwise rotation of the cylinder valves, high-pressure oxygen from the oxygen cylinder through a vacuum valve to ≥ 1.2L/min enter airbags, hands off the the qi plate nourishing stop. Negative pressure respiratory the qi plate inward contraction, oppression the qi lever to open the qi institutions, oxygen ≥ 60L/min filled airbag when the airbag muster the qi plate left the qi rod, qi stop. If the air pressure within the respiratory system than the exhaust valve exhaust pressure, the gases from the exhaust valve overflow. As you inhale, the air bag in the oxygen enter the body through the mouth with. Exhale, the gases pass through the breath hose into the clean tank, the gas carbon dioxide in the chant placed in the clean tank of CO2 absorbent absorption, the remaining gas into the airbag, according to a respiratory cycle.
