Working procedd and connection of HO-A01-01G valve oxygen concengtrator

Initial state:

In the initial state, the spring causes the spool ejector to stay on the battery valve, and at this time, air is injected into the molecular sieve tube. In this state, turning on the compressor to supply air will make the two molecular sieve tubes pressurized at the same time, which is used to increase the pressure in the molecular sieve tube most quickly and increase the adsorption capacity of the molecular sieve, thereby generating high-concentration oxygen.

A tube supplies oxygen and B tube is in desorption state:

When tube A is in the oxygen supply state, the solenoid valve controlled by tube B works and guides high-pressure gas into the control chamber of tube B, pushing the valve core push rod to stay in the direction close to the compressor air inlet. At this time, the molecular sieve tube of tube B exhausts air outward. In this state, when the compressor supplies air to tube A, the molecular sieve tube of tube A will be pressurized, increasing the adsorption capacity of the molecular sieve and thus generating high-concentration oxygen. While tube B quickly exhausts and reduces pressure, and obtains part of the high-concentration oxygen separated from tube A through the purge hole between the two tubes for desorption. After desorption, it can be pressurized again for adsorption action.

B tube supplies oxygen and A tube is in desorption state:

When tube B is in the oxygen supply state, the solenoid valve controlled by tube A works and guides high-pressure gas into the control chamber of tube A, pushing the valve core push rod to stay in the direction close to the compressor. At this time, the molecular sieve tube of tube A exhausts air outward. In this state, turning on the compressor to supply air to tube B will pressurize the molecular sieve tube of tube B, increasing the adsorption capacity of the molecular sieve and thus generating high-concentration oxygen. While tube A quickly exhausts and reduces pressure and obtains part of the high-concentration oxygen separated from tube B through the purge hole between the two tubes for desorption. After desorption, it can be pressurized again for adsorption action.

This cycle continues to form a continuous oxygen supply process.
