The Development Of Respirators

1. Under the premise that the existing wearing weight remains unchanged, the method of increasing the rated working pressure and volume of the gas cylinder is used to increase the gas storage capacity of the gas cylinder. Try to use new materials and new technology to reduce the weight of the full face mask, cylinder valve, air supply valve, pressure reducer, back frame and other components, leaving room for the increase in the weight of the cylinder. The maximum rated working pressure of the gas cylinder is 30 MPa. If it is increased to 60 MPa, the gas storage capacity of the gas cylinder will double, and the use time will also double; if the volume of the gas cylinder doubles, the gas storage capacity of the gas cylinder will increase Doubled, the use time also doubled accordingly. With the organic combination of the two, the gas storage capacity will increase geometrically.

2. Reduce unnecessary gas consumption. For example: "breathing ambient air" and "breathing cylinder air" can be switched freely, filter respirator and air respirator can be switched freely, etc.

3. The application of electronic sensing technology in air breathing apparatus forms an intelligent air breathing apparatus. When the external toxic gas concentration exceeds the limit or the oxygen concentration is lower than 17%, it will automatically switch to an air respirator.
