example
[0021] The drip irrigation belt is made of a section of thin-walled circular tube radially pressed into a structure with a flow channel at the middle part with a mold. The mold is rolled once to form two parallel flow channels along the radial direction, and the water outlets are shared. After successful pressing, two drip irrigation belt products are formed by cutting radially from the middle.
[0022] The following table shows the pressure and flow data tested in our experiment, which shows that the micro-pressure drip irrigation performance of the drip irrigation belt is good.

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.
Description
technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and relates to a drip irrigation belt, in particular to a single-wing double-channel bypass flow micro-pressure drip irrigation belt. Background technique [0002] Water-saving irrigation is the main measure taken by countries all over the world to develop modern agriculture. As an advanced high-standard irrigation technology in water-saving irrigation, drip irrigation has been adopted by more than 100 countries in the world. Among them, drip irrigation has the most significant advantages such as water saving, production increase, high efficiency and environmental protection, and can be widely used in fields, greenhouses, greenhouses and ecological gardens for economic crops such as cotton, vegetables, flowers, urban green belts, gift melons and fruits and fruit trees. water for irrigation. [0003] At present, in the world, drip irrigation products generally have te...
