The mouth of a river 3 is corresponding with 8 position of drip being located at pipeline 7 and is connected to.
A pitting drip emitter 2 is arranged every 0.5m in 7 inner wall of pipeline, and can be according to crop spacing again cloth
Set interval.
Cell width a is 1.2mm in the 4 pit flow passage unit structure of pit runner, and unit entrance length c is 0.8mm,
1 length of water fender is that d is 1.7mm, and 1 width of water fender is that b is 0.2mm, on dentalation at the top of between cog at the top of lower between cog away from
It is 4mm from e.
The working principle of the pitting drip irrigation appliance are as follows:
When present apparatus work starts, water flow is set to enter pipeline 7, fluid can be entered by the filter plate 6 of pitting drip emitter 2
Water inlet 5, by entering pit runner 4 after water inlet 5, because flow channel shape limits, fluid sudden expansion shunting energy dissipating decompression, because of pit
Contain water fender 1 in runner 4, racing occurs after water fender 1 and converges for sudden expansion water flow, after by another identical structure, according to
Secondary circulation is gone down, and when fluid flows out pit runner 4, into water outlet 3, passes through formation drip at the drip 8 that is connected with water outlet 3
Pipeline 7 is flowed out, achievees the purpose that uniformly to pour water.
The beneficial effects of the present invention are:
1, apparatus of the present invention construct the novel pit stream that the increases such as a kind of shunting, racing, confluence dissipate by the optimization to runner
The drip emitter in road.
2, apparatus of the present invention can be effectively reduced the flow stance index of drip emitter.
3, apparatus of the present invention operation is fairly simple, and component is made by highstrenghtpiston, and service using life is long.
