Description

technical field [0001] The application relates to the field of medical molecular sieve pressure swing adsorption oxygen production, in particular to a multi-channel gas flow switching device for medical molecular sieve oxygen production system. Background technique [0002] At present, the medical molecular sieve oxygen production system has become the most important oxygen source in major hospitals. The timing control of the intake, exhaust and pressure equalization of each adsorption tower is the core process of the oxygen production system. The intake and exhaust process of the adsorber The control gas switching valve group is the core equipment to realize the process, and its operation status directly determines the reliability, oxygen production capacity and energy consumption of the equipment. Therefore, there are high requirements for the reliability of the gas switching valve group and its components, and the loss of fluid resistance. Especially in the VPSA (Positiv...
