Abstract

The invention discloses a drip irrigation emitter and a drip irrigation system. The drip irrigation emitter comprises a water inlet, a water outlet and a plurality of flow channel units arranged between the water inlet and the water outlet, wherein each flow channel unit comprises a first main flow channel, a second main flow channel and a plurality of branch flow channels which are arranged in a communication manner, the first main flow channels are arranged close to the water inlet, the second main flow channels are arranged close to the water outlet, the branch flow channels are arranged between the first main flow channel and the second main flow channel, and the branch flow channels are arranged along the tangential direction or the radial direction of the second main flow channel. When entering the first main flow channel, water flow impacts the first main flow channel to dissipate energy, then forms split flow through the branch flow channels to dissipate energy, and then tangentially enters the second main flow channel to form vortexes to dissipate vortex energy, or radially enters the second main flow channel to dissipate energy in a hedging manner and in a turbulent flow manner, so that a better energy dissipation effect is achieved, and the energy dissipation effect is not limited by the size of the flow channels.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a drip irrigation dispenser and a drip irrigation system. Background technique [0002] The drip irrigation emitter is the core component of the drip irrigation system. The hydraulic performance and anti-clogging ability of the emitter directly determine the irrigation quality and system life of the drip irrigation project. Therefore, the rational design of the drip irrigation emitter and the improvement of its anti-clogging ability and hydraulic performance are very important for improving the drip irrigation system. It is of great significance to improve the performance, improve the service life of the system and reduce the cost of the system. [0003] The flow channel of the drip irrigation emitter in the prior art usually adopts a labyrinth, and the turbulent flow and pressure reduction of the water flow are mainly performed through the complicated boundary conditions...
