description The utility model discloses a central oxygen supply system. The central oxygen supply system comprises at least one first pressure reducer; an air source inlet of a pneumatic actuator on each L-shaped pneumatic three-way ball valve is communicated with a main air supply source, and a first pressure reducer is arranged on a pipeline between each air source inlet and the main air supply source; a first valve port of each L-shaped pneumatic three-way ball valve is communicated with a main air supply source, a second valve port of each L-shaped pneumatic three-way ball valve is communicated with a standby air source, and a third valve port of each L-shaped pneumatic three-way ball valve is communicated with an oxygen output port; and each third valve port is communicated with the corresponding first valve port. According to the utility model, when the pressure of the main gas supply source is reduced, the main gas supply source can be automatically switched to the standby gas source, and when the power is cut off
