Composition of central oxygen supply system:

1. Oxygen station section: oxygen cylinders, oxygen meters, oxygen busbars, high-pressure halberds, high-pressure pipe fittings, valves, oxygen control boxes, sound and light alarms, pressure reducing and stabilizing devices, etc;

2. Pipeline section: degreased copper pipeline, oxygen pressure gauge, oxygen valve, etc;

3. Oxygen terminal part: ventilator, oxygen warming bottle, equipment belt, etc;

Operating principle:

The oxygen source provides a continuous supply of oxygen to the system. When working, it first uses oxygen from one set of bottles, and when the oxygen in that set of bottles is depleted, it can switch to another set of oxygen bottles

Continuing normal oxygen supply, the alarm simultaneously emits sound and light alarm signals to remind users to replace in a timely manner. The system can maintain stable oxygen supply in a cyclic state without interruption.
