Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] see figure 1 , 2, 1) firstly adopt the design software pro / e to establish the parametric CAD pressure compensation dripper model 1 of the dripper according to the flow requirement of the emitter;

[0011] 2) Then, on the basis of the pressure compensation dripper model 1, an outer tube with a window is designed, and the outer tube and the pressure compensation dripper model 1 are integrated to form a model of a pressure compensation emitter integrated dripper 2 with a window, And cut a rectangular gap on the outer tube at the place opposite to the pressure compensation area 3 of the pressure compensation dripper as the pressure regulating diaphragm loading window 4, in order to close the diaphragm loading window 4 on the outer tube, install the diaphragm The model of the outer pipe sealing block 5 is also set on the window 4;

[0012] 3) Data convers...

Abstract

The invention discloses a rapid development method of a pressure compensation emitter. The method is based on laser rapid prototyping technology. After designing an integrated model of a pressure compensation emitter with a window according to design requirements, the emitter is processed by a laser rapid prototyping machine. After the test piece is loaded with the diaphragm, it forms an integrated experimental original, which is connected to the comprehensive performance test bench of the emitter, and the experimental finalization of the pressure compensation emitter is quickly completed. The emitter model of the present invention adopts parametric modeling, only needs to modify the corresponding parameters to meet the design requirements, further shortens the development cycle of the emitter, and completes the rapid and accurate finalization of the emitter. Compared with the traditional method, the product finalization of the emitter can be completed without the need for molds and drip irrigation pipe production lines, the cycle is significantly shortened, and the cost is significantly reduced.

Description

technical field [0001] The invention relates to a rapid development method of an irrigator for water-saving irrigation, in particular to a rapid development method of a pressure compensation irrigator. Background technique [0002] Among the various existing emitters, the ordinary type adjusts the water output through the water supply pressure, while the pressure compensation type emitter ensures that the water output is basically uniform under different inlet pressures. The pressure compensation emitter can irrigate evenly, and the number and length of the drippers arranged in the same pipe are greatly increased, which reduces the cost of the pipeline, and is suitable for drip irrigation of crops in areas with large terrain fluctuations such as mountainous areas and hilly areas. The pressure compensation sprinkler is generally composed of three or two pieces, the three pieces are composed of the dripper body, the dripper cover and the compensation diaphragm, and the two pie...
