Description
Technical Field
The utility model belongs to the technical field of manufacturing of douches, and particularly relates to a douche based on the Tesla one-way valve principle.
Background
Agricultural irrigation is indispensable in agricultural development, wherein drip irrigation is widely promoted, and water flows out in the form of water drops to moisten soil on the surface of crops and near roots. The most core component in the drip irrigation system is an emitter which achieves the effect of energy dissipation through the change of the structure and the form of a flow channel, and the flow pressure of the emitter is adjusted to further improve the flow stabilizing performance of the emitter, so that the flow is changed from a flow jet shape into a dripping shape.
The change of the flow passage structure of the irrigator and the selection of parameters directly influence the hydraulic performance of the flow passage structure of the irrigator, and the essence of the flow stabilizing performance of the irrigator is the energy loss of water flow in the flow passage of the irrigator. In recent years, more and more researchers are dedicated to research on the energy dissipation mechanism of water flow in the flow channel of the emitter so as to improve the effect of drip irrigation. The energy dissipation of rivers mainly realizes through head loss, and head loss mainly falls into two types: loss of on-way head and loss of local head. The most common irrigators in the market at present can be divided into a labyrinth type and a spiral type according to the flow passage structure, and because the flow passages of the two types of irrigators are long and small in diameter, the energy dissipation effect of the irrigators is mainly realized by the loss of a water head along the way. At present, the irrigation emitter increases the water head loss along the way through the change of a flow channel, thereby increasing the energy consumption of the water flow and further achieving the purpose of stabilizing the flow. Therefore, optimization and innovation of the flow passage structure of the emitter and the diversity of energy dissipation modes of the flow passage structure become important points of research and development of the emitter.
