Working principle of air respirator
The gas flow mode of this respirator is open circuit. When the cylinder valve is opened, the high-pressure air stored in the cylinder is reduced to medium pressure by the pressure reducer, and then the air supply valve limits the flow to >/, and continuously supplies the user with breathing. When inhaling, the piston on the air supply valve automatically opens to provide air flow. When exhaling, the piston closes and the exhalation valve opens to expel exhaled air out of the system. Since the air supply volume of the air supply valve is greater than the inhalation volume, positive pressure is always maintained in the mask, effectively preventing the intrusion of toxic and harmful gases from the outside.
