Structural Design and Simulation of the Oxygen Regulator

With the application of electronic regulation technology in oxygen supply system, considering the pressure loss caused by the dynamic flow of gas, the position of pressure signal collected by the controller needs to be taken into comprehensive consideration, and a new pulmonary is put forward for the electronic regulation oxygen supply system. In this paper, aiming at the problem of respiratory gas pressure drop caused by the pressure loss in the oxygen supply system pipeline, ejector assembly was designed in the oxygen regulator to improve the outlet gas pressure of the regulator, and the corresponding fluid model was established. Through the fluid numerical simulation calculation and analysis, the working mechanism of the ejector assembly was studied.
