Title:
DRIP IRRIGATION TUBE AND DRIP IRRIGATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/021074
Kind Code:
A1
Abstract:
This drip irrigation tube has a tube comprising a first flow path and a second flow path, and an emitter. A first through hole is open to the first flow path and the second flow path. A second through hole is open to the second flow path. The emitter comprises: a water intake part for taking in an irrigation liquid through the first through hole; an ejection part for ejecting the irrigation liquid to the outside through the second through hole; a discharge part for discharging the irrigation liquid to the second flow path; a first emitter flow path connecting the water intake part and the ejection part; a second emitter flow path connecting the water intake part and the discharge part; a pressure decreasing flow path that decreases the pressure of the irrigation liquid taken in from the water intake part and guides the irrigation liquid to the ejection part; and a flow rate adjusting part that guides the irrigation liquid to the discharge part only when the pressure of the irrigation liquid exceeds a predetermined pressure.
