AI Technical Summary

⚠Technical Problem

Existing industrial gas precision premixing mechanisms allow gas to enter the device rapidly after the valve is opened, leading to gas accumulation and an increased concentration gradient, resulting in poor mixing performance.

⚗Method used

The design employs a metering component and a pressure relief component. A cam drives the sealing plug to move back and forth to achieve metered air intake. Combined with the stirring action of the stirring blades, the gas concentration boundary layer is broken, the concentration gradient is reduced, and stratification is suppressed. At the same time, a pressure relief pipe is set to prevent excessive pressure.

🎯Benefits of technology

It significantly improves gas mixing efficiency, increases gas contact area, ensures mixing uniformity, and prevents safety risks caused by excessive internal pressure.
