A kind of respiratorArt
The invention belongs to personal respiratory protection safety device, more particularly to a kind of respirator.
Background technology
At present, the positive pressure respirator of sizing production both at home and abroad has key technical problem to be solved：(1) there are considerable respirator such as Germany BG4 respirator malleation technologies unqualified.When respiratory capacity exceedesDuring 50L/min (exceed heavy work duty work), the pressure of inspiration(Pi) of the respiratory circulatory system of respirator withThe increasing of respiratory capacity gradually becomes negative pressure value, that is, respirator has lost positive-pressure function and has been changed into suction typeRespirator；(2) in the presence of the external force-spring force loaded on air bag or gas cabin, the expiration of respiratorResistance is significantly increased.
In a word, such respirator is worn not only dangerous but also very uncomfortable.
