Buried Telescopic Sprinkler Irrigation

Buried telescopic sprinkler irrigation is an irrigation system that installs nozzles underground, and its working principle is as follows:

1. Water pressure drive: The system extracts water from the water source through a water pump and adds water pressure to the expansion pipe.
2. Expansion tube extension: When the water pressure reaches a certain value, the expansion tube extends upwards under the action of water pressure, bringing the nozzle above the ground.
3. Spray nozzle: After the nozzle extends out of the ground, water sprays out of the nozzle for irrigation.
4. Retraction of expansion pipe: After irrigation is completed, the water inside the expansion pipe flows back through the reflux channel, forming a negative pressure inside the expansion pipe cavity. Under the action of the negative pressure, the expansion pipe quickly retracts, retracting the nozzle underground.
