The mobile long-tube respirator provides respiratory protection for personnel working in hazardous gas production areas for a long time and emergency rescue personnel in an oxygen-deficient environment full of toxic and harmful gases. It is composed of a mobile gas source vehicle and an escape emergency gas cylinder. For 2 people to use at the same time, the working area is up to 50 meters.
1. The mobile gas source consists of 4 gas cylinders to form 2 independent gas cylinder groups. The two groups of gas cylinders and the pressure reducer are controlled by a one-way valve. The high-pressure gas source will not cause backflow between the two groups of gas cylinders. The gas cylinders can be opened and used one by one, group by group, or all of them can be opened and used at the same time, which can be freely determined according to specific needs. Each group of gas cylinders has a pressure relief valve, which can release the high-pressure gas in the high-pressure pipe to facilitate the replacement of gas cylinders, but will not release the low-pressure gas at the output of the pressure reducer and the gas in another group of gas cylinders.
2. The mobile gas source and the escape gas bottle are combined through the waist valve, and the gas of the mobile gas source is directly used under normal conditions. When an emergency occurs and you need to evacuate the scene quickly, you can open the escape gas cylinder valve and evacuate to a safe area.
3. The mobile air source is equipped with one 30-meter gas supply pipe and two 10-meter gas supply pipes, with a maximum stacking length of 50 meters. There is a Y-shaped tee on the 30-meter pipe, which can be used by 2 people to use the compressed air of the mobile air source at the same time.
