AI Technical Summary
Existing drip irrigation systems suffer from inconsistent drip uniformity and easy clogging of drip heads, especially in long-distance drip irrigation pipelines where uneven drip rate and clogging are prominent issues.
The system adopts a pressure-compensated underground drip irrigation head design, which combines a reversing component and a spiral component to form a reversing flow channel, a pressure regulating flow channel, and an additional flow channel. By adjusting the number of spiral turns and the width of the groove, the uniformity of drip irrigation pressure can be controlled, and an anti-backflow mechanism is provided to prevent clogging.
It achieves uniform drip irrigation volume over a wide pressure range, simplifies the installation and commissioning of large-scale drip irrigation heads, reduces the risk of clogging, and improves the stability and efficiency of the drip irrigation system.
