On the basis of embodiments 2 and 3, this embodiment improves a halo irrigation method, and the only difference from embodiment 3 is that:
and in the step of implementing the corona irrigation, when water is supplied, the third valve is closed, and after the water supply is finished, the third valve is opened, so that all residual water in the longitudinal branch pipe or the longitudinal main pipe flows into the corresponding shell and is fully precipitated in the shell. At the moment, water containing impurities is hardly reserved in the longitudinal branch pipes or the longitudinal main pipe, and almost all the water containing impurities enters the shell to enter an impurity settling procedure, so that the pollution of the water containing impurities reserved in the longitudinal branch pipes and the longitudinal main pipe for a long time on the pipeline is avoided.
The working principle of the invention is as follows: when water is supplied, water enters the longitudinal main pipe through the water inlet pipe, then flows into the transverse main pipe through the longitudinal main pipe, and flows into each longitudinal branch pipe through the transverse main pipe, when the water pressure is high enough, the floating ball in the pressure water taking valve 14 moves downwards, the pressure water taking valve 14 is opened, water flows enter the corona irrigation pipe, and slowly permeates into the planting matrix through the filtration of the filter cotton; when the water in the planting matrix is saturated, the first valve is closed, negative pressure is formed in the water delivery main pipe and the longitudinal branch pipe at the moment, and the pressure water taking valve is closed by the floating ball due to the acting force of the negative pressure; meanwhile, the flap-shaped spring pieces 7-2-3 can be closed under the action of negative pressure to prevent the impurity-containing water in the shell from flowing backwards, and after the flap-shaped spring pieces are closed, impurities are precipitated and enter the impurity precipitation area 22; when the next water supply is carried out, the impurities are precipitated again, and after a certain time interval, the impurities can be discharged through the blow-off pipe.
The corona irrigation pipe provided by the invention comprises an inner pipe, filter cotton and a fixing net, after the filter cotton absorbs water and is saturated, water can be slowly irrigated in a surface diffusion mode (the curved surface of the outer wall of the corona irrigation pipe) into the planting matrix, and the filter cotton can block the planting matrix and prevent the planting matrix from flowing back to a pipeline while solving the problem of water supply pressure scouring damage. The filter cotton is divided into three layers, which can be non-woven fabric, absorbent cotton and non-woven fabric. The filter cotton is stably wrapped by the fixing net to prevent bursting and stripping.
The invention connects the pressure water intake valve through the folding hose, can adjust the position of the pressure water intake valve, and is convenient to connect with the longitudinal branch pipe. When the pollution discharge device is used, impurities fall into the shell through the open flap-shaped spring pieces 7-2-3 along with water flow, and form backflow in the shell until the pressure is reduced and the impurities fall; when the first valve is closed, the flap-shaped spring piece 7-2-3 is closed under the action of reflux pressure caused by negative pressure of the longitudinal branch pipe, so that impurities are prevented from refluxing; after the pressure is reduced, the petal-shaped spring piece 7-2-3 is opened due to the elasticity of the petal-shaped spring piece. The shell used by the sewage discharge device is in an inverted cone shape with a heart-shaped section, the shell is designed according to the backflow direction of water flow falling, water containing impurities can fully flow back in the shell to consume energy, further the impurities are fully precipitated, and the shell is matched with the intercepting spring piece 7-2 to effectively prevent the impurities from flowing back to the longitudinal branch pipe.
The upper end of the longitudinal main pipe is provided with the one-way filter valve, the upper end of each longitudinal branch pipe is provided with the one-way valve, the flowing direction of water can be accurately managed, water backflow is avoided, and particularly backflow pollution of impurities is avoided.
