Problems solved by technology

At present, the micro-pressure water-saving drippers all adopt the structure of the flow channel under normal pressure. Under the micro-pressure condition, in order to achieve the energy dissipation effect, the number of units of the labyrinth flow channel is usually increased, or the cross-sectional area of ​​the flow channel is reduced, which causes Increased manufacturing costs, but also increased the probability of clogging

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] Referring to Fig. 1, the present invention is based on the micro-pressure emitter integrated rapid development platform technology, including the emitter 1 and the flow channel 2 opened inside the emitter 1, and the said several flow channels 2 are connected to each other, and the flow channel 2 Use circular arc grid flow channel or 80° round grid flow channel. Among them, the distance from the grid center to the upper boundary of the 80° rounded grid flow channel is 0.6mm, the grid width is 0.5mm, the outer circle radius of the circular arc grid flow channel is 0.56mm, and the inner circle radius is 0.5mm . Using the parametric CAD software PRO / E modeling, after the two-phase flow CFD simulation experiment, the unit size and unit number are determined, so that the flow rate under the micro-pressure condition (5m water head) reaches 1.47L / h and 1.83L / ...

Abstract

The present invention relates to a grid type flow passage water-saving douche, which includes the douche and a plurality of flow passages which are communicated to each other and use circular arc type grid flow passages or 80 degrees round whole grid flow passages are provided in the douche. The present invention is different from the one-dimensional array form of the conventional labyrinth flow passage, while uses the two-dimension array, so that the fluid can form impact and energy exchange at confluences of different branches inside flow passage, thereby achieving the object of energy dissipating, and multi-branching flow passages can effectively reduce the generation of stoppage.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a water-saving sprinkler for grid-shaped flow channels used in agricultural water-saving irrigation equipment. Background technique [0002] Drip irrigation technology is currently the most effective and efficient irrigation technology in water-saving irrigation, but it is also "the most expensive irrigation technology". The general working pressure of the drip irrigation system is 10 meters of water head. When it is at a micro pressure (below 5 meters of water head), it can reduce the material requirements of the irrigation system water distribution pipeline and the thickness of the emitter, thereby greatly saving investment and reducing costs. The water-saving irrigator is installed on the final pipeline of the drip irrigation system. According to the needs of the crops for water, the pressure water transported by the water pipeline is uniformly and slowly di...
