Abstract

The invention discloses an irrigation emitter based on a Tesla one-way valve principle and an irrigation system thereof, and belongs to the field of irrigation emitter manufacturing. The irrigation emitter based on the Tesla one-way valve principle comprises a water inlet pipeline, a water outlet pipeline and a flow channel device, wherein the flow channel device comprises a main flow pipeline located in the middle of the flow channel device and a plurality of flow channel units uniformly communicating in series and oppositely arranged on the upper side and the lower side of the main flow pipeline; each flow channel unit is sequentially provided with a plurality of barriers from bottom to top, and the barriers divide the flow channel units into capillary tubes and shunting capillary tubes; the capillary tubes communicate with the main flow pipeline and located on the peripheries of the barriers, each shunting capillary tube is located between the two adjacent barriers, and an inlet and an outlet of each shunting capillary tube communicate with the corresponding capillary tube. Water flow flows into the irrigation emitter based on the Tesla one-way valve principle to generate an inclined hedge and a vortex, so that the local head loss of the water flow is increased, the energy consumption of the water flow is further increased, the flow speed of the water flow is further reduced, and the irrigation uniformity is improved.

Description

technical field [0001] The application belongs to the technical field of emitter manufacturing, and in particular relates to an emitter based on the Tesla check valve principle and an irrigation system thereof. Background technique [0002] Agricultural irrigation is indispensable in the development of agriculture, among which drip irrigation is widely respected, and the water flows out in the form of dripping water to moisten the crop surface and the soil near the root system. The core part of the drip irrigation system is the emitter. The emitter achieves the effect of energy dissipation through the change of the structure and form of the flow channel, and adjusts its water flow pressure to improve the steady flow performance of the emitter, so that the water flow changes from a jet to a drip. . [0003] The change of the structure of the emitter flow channel and the selection of parameters directly affect its hydraulic performance, and the essence of the steady flow perf...
