AI Technical Summary
Traditional DC low-pressure air pump valves lack guide vanes and flow dividers under high-speed airflow, resulting in disordered turbulence and Karman vortex street effect, causing severe disturbance and wear.
The design features a three-hole distributed air inlet end, with the secondary air inlet pipe secured by a docking buckle and locking screw, ensuring smooth airflow into the valve body and utilizing airflow inertia to increase flow rate and reduce wear.
This achieves stable and uniform airflow, increases the flow rate of the air pump, extends its service life, and reduces valve wear.
