Glue thin film is made.Fei Shi mechanisms by rubber film, transmit lever and enter oxygen valve etc. and constitute.The deformation of rubber film passes through one
Individual transmission lever controls the unlatching into oxygen valve, and the deflection of rubber film directly controls the size into oxygen valve opening.
The oxygen therapy pipeline of mask is connected to the hollow cavity of breathing regulator, and when user is breathed by mask, hollow cavity is shape
Into negative pressure, rubber film caves inward, and so opens the valve into oxygen by lever, and inspiration capacity is bigger, and hollow cavity is formed
Negative pressure it is bigger, it is bigger to enter oxygen valve opening, enters that amount of oxygen is more, can so meet the oxygen consuming amount of different users.
Oxygen concentration controlling organization is arranged on the side of hollow cavity, is connected with hollow cavity by an aperture for entering air
Connect.Oxygen concentration controlling organization is by aneroid capsule and enters air register and constitutes, and aneroid capsule can be with the change of ambient pressure
Expand (thickening) and reduce (thinning), enter the size of air register using this characteristic de-regulation of aneroid capsule.
Breathing regulator utilizes this two parts mechanism so as to supply the suction gas of aircrew's different oxygen concentrations, to ensure
There is no anoxia during aircrew's flight.But the type actuator is present, and mechanism is more, volume is big, weight is heavy, difficult in maintenance etc. ask
Topic.
