Marine EC / MED Ship\'s Wheel Mark Air Breathing Apparatus With Two Cylinder / SCBA Set??

Self Contained Air Breathing Apparatus are widely used in fire fighting, chemical industry, shipbuilding, petroleum, metallurgy, electricity, warehouses, laboratories, mines and other departments, for firefighters or emergency rescue personnel in smoke, gas, steam and oxygen and other conditions can be safe and effective conduct of fire fighting, disaster relief and rescue work, firefighters, and rescue and ambulance personnel to the ideal of personal respiratory protection equipment.

The main technical parameters

Working Principle

Stored in the high-pressure compressed air inside the cylinder through the cylinder valve into the valve, and outlet pressure gauge shows the air pressure inside the bottle. High-pressure gas decompression of the medium-pressure gas into the 0.7MPa, the Central-pressure input to the joins in on the supply valve in the mask. For the valve according to the user\'s breathing requirements can provide the necessary flow of air. Users begin to wear full cover, then will be available for plug valves and comprehensive cover, with the automatic positive pressure gas supply button pressed, the valve is opened, the gas entered the hood. Breath, the mask call on the valve is opened, the exhaled gas emissions outside the system. At the same time the pressure to overcome the positive pressure expiratory elastic springs acting on the respiratory membrane, the respiratory diaphragm valve stem in a gradual loss of the force, so that for the valve to stop gas supply. When the internal body for the valve failure, it can press the button to manually supply an additional qi.

Note: for valve normal working hours, without holding down the button for additional qi and pressure relief. Only in very necessary or in the operation of inspection in order to press an extra button qi and pressure relief.

Scope

????A. smoke hypoxia and there is gas, smoke, steam pollution, atmospheric environment;

????B. -30 ° C ~ +60 ° C, relative humidity 0 ~ 100%, atmospheric pressure 70Kpa ~ 125Kpa of the atmospheric environment.
