Embodiment Construction

[0010] According to the above-mentioned technical scheme, when using the method of the present invention to design the dripper flow channel, it is required that the boundaries on both sides of each unit of the flow channel (see Figure 1) adopt an arc (approx. 180°) surface.

[0011] This embodiment takes the arc-shaped curved surface as an example. Because the arc-shaped curved surface (hereinafter referred to as the curved surface) is relatively simple in the design and manufacturing process, it is very easy to implement. Of course, curved surfaces of other shapes can also be set according to the above-mentioned technical solutions. Purpose.

[0012] The arc-shaped curved surface consists of two parts, that is, the diversion surface 3 and the vortex surface 4. The curved surfaces are naturally transitioned and connected to form the vortex curved surface 2. The curvature of the first half is small (the radius of the arc of the diversion surface 3 is relatively large), and its ...

Abstract

The flow passage structure design method for anti-blocking turbulent irrigator is proposed based on the disturbance flow and eddy flow theory in hydraulics, and the flow channel unit has side arced surfaces with eddy flow characteristic and arranged alternately. The flow cannel thus designed has smooth sides in streamline structure without zero speed area and fine particle deposition, and automatically formed disturbance and eddy flow with scouring to silt and foreign matter. The present invention has excellent silt flushing anti-blocking effect and energy dissipating effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and relates to drip irrigation technology, in particular to a flow channel structure design method of a turbulent-flow anti-clogging emitter. Background technique [0002] Drip irrigation is an advanced water-saving irrigation technology. Compared with other irrigation technologies, drip irrigation technology has a wide range of applications, uniform irrigation, and significant water-saving and production-increasing benefits. Water) irrigation, therefore, drip irrigation technology has very broad application development prospects. For more than half a century, drip irrigation equipment has been rapidly developed and improved, and drip irrigation technology has also been rapidly promoted. Although the drip irrigation technology itself has been relatively perfect, the drip irrigation system still has the following shortcomings: the emitter is e...
