Embodiment Construction

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

[0010] See Figures 1, 2, and 1) First, use the design software pro / e to establish a parametric CAD pressure-compensated dripper model 1 for the emitter according to the flow requirements 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 conversi...

Abstract

The invention relates to a method for developing pressure compensation drenching apparatus, wherein based on laser quick shaping technique, designs the mode, uses laser quick shaper to process test element of drenching apparatus, fills membrane, to form the test one, feeds into test table, quickly completing the test mode of drenching apparatus. The invention uses parameter mode, to reach demand, shorten develop period. Compared with traditional method, it can avoid mould and product line.

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...
