Jining Dali Industrial Minerals Co

Isolated compressed oxygen self-rescuer
Mainly suitable for the following environments
)
Provided to underground coal mine workers and rescue team members in the event of natural disasters such as fires, gas explosions or gas outbursts. When the respirator fails, it can be safely evacuated from the disaster area.
)
It is used for on-site personnel to escape when toxic and harmful gases escape in the chemical industry department.
)
It is used for escape when natural gas or other toxic gases burst out in large quantities during oil extraction operations.
)
For high-rise buildings, when a fire breaks out, people in the building wear it to escape or use it when waiting for rescue.
)
For other departments to use for escape in toxic and harmful gases or hypoxic environments.
Isolated compressed oxygen self-rescuer is powerful
Working principle
When using the rescuer, turn the cylinder valve counterclockwise, and the high-pressure oxygen will decompress from the oxygen cylinder through the pressure reducing valve and enter the air bag. Replenishment stops when your hand leaves the air pressure plate.
When the respiratory system is under negative pressure, the air supply pressure plate contracts inward, pressing the air supply rod to open the air supply mechanism, and oxygen is/is filled into the air bag. When the air bag inflates, the air supply pressure plate leaves the air supply rod, and the air supply stop.
If the air pressure in the respiratory system exceeds the exhaust pressure of the exhaust valve, the gas will overflow from the exhaust valve.
When inflating, the oxygen in the air bag enters the human body through the mouthpiece.
When breathing, the gas enters the clean tank through the exhalation hose. The carbon dioxide in the gas is absorbed by the absorbent placed in the clean tank. The remaining gas enters the air bag and forms a breathing cycle.
