Can the venturi gas mixer adjust the gas ratio?

Venturi ejector mixer uses the pressure of liquefied gas to spray at high speed through supersonic nozzle, forming negative pressure in the suction chamber, ejecting external air, and fully mixing with liquefied gas in Venturi tube and outputting. According to the change of pipe network pressure, the equipment can be started and stopped automatically. Because air is injected by negative pressure formed by liquefied gas injection, the injection pressure of liquefied gas should not be too low, generally above 0.3MPa, and the mixing ratio can be adjusted within a certain range, but the output mixed gas pressure is low, generally below 0.05MPa. To realize its high-pressure transportation, it is necessary to install air with pressure outside the suction room to form a pressurized Venturi mixer, which can greatly improve the transportation pressure of equipment and meet the requirements of long-distance transportation.
