Abstract

The invention discloses a flow micro-pressure drip irrigation tape with a single wing and double channels, which comprises a water pipeline, a drip irrigation tape wing and n working units; the drip tape wing is adhered to the water pipeline; the n working units are distributed on the drip tape wing alternatively. The working units comprise a water inlet, a double-channel flow passage and a water outlet; the water inlet is communicated with the water pipeline; the water inlet and the water outlet are communicated through the double-channel flow passage; the double-channel flow passage consists of continuously distributed serrated passage units. The part passage surface of the drip irrigation tape of the invention is a labyrinth-type serrated flow passage; the mutual erosions of the continuous serrated structure and water flow cause local energy dissipation to be more outstanding and ensure an emitter to have more efficient energy dissipation effect. The invention has better effluent evenness, anti-clogging performance and economy. The drip irrigation tape is suitable for irrigation under low water pressure and is applied to irrigation under the conditions of complex terrain and simple equipment.
