Description

The invention relates to agriculture and can be used for irrigation from closed irrigation systems,

The goal is to increase operational reliability and simplify the design.

The drawing shows a self-injection irrigation system, side view, section.

The irrigation system includes water distribution structures for a closed irrigation network containing a well 1. Divided into two chambers by a partition 2, in which an outlet opening 3 is made. On the partition 2 there is a siphon 4, the hood of which is equipped with a vacuum tube 5. The bottom of the first chamber of the well 1 before the partition 2 covered

a layer of gravel material 6 and reported by a water outlet tube 7 connecting the first chamber of the well 1 with an additional chamber 8. An additional chamber 8 is placed in the lower outer part of the second chamber of the well 1 and in its upper part connected by means of an outlet tube 9 equipped with regulators 10. the control tank 11. In turn, the control tank 11 communicates in its upper part with the vacuum tube 5 of the siphon hood 4.

The control tank 11 also has a calibrated drain hole 12 in the bottom (valve - valve is not shown) and a drain hole 13 in the side wall under the lid. The end of the vacuum tube 5 in the tank 11 is lowered slightly below the side drain hole3

13. The hole area of the outlet tube is 2–4 times the cross-sectional area of the drain calibrated hole 12 in the bottom of the control tank. Drain hole 12 may be blocked by a valve (or valve) and regulate the discharge of water until it is completely empty. On the poly. In a direct pipeline 14, water outlets 15 (micro hydrants) are located.

The irrigation system works next- 10

 - l-vHe irrigated area perpendicular p-. . but fenders laid irrigation pipe 14 with a discharge outlet 15 and with water distribution structures.

When water flows through the irrigation pipeline 14, water flows through the rocky material .6 and through the water outlet pipe 7 fills the additional chamber 8, and through the outlet pipe 9 the regulator 10 20 controls the control capacity 11. Excessive water flow, if any, is poured out in the furrow through the calibrated adjustable holes 12,13 in the control tank 11. The automatic activation of 25 siphon 4 in the work is carried out in the presence of a lower end of the siphon flooding through the outlet 3 in the partition 2 and when the outlet end of the siphon is flooded smart the tube 5 in the control tank 11, while 30 of this, the rocky material 6 simultaneously prevents the deposition of sediment in the additional chamber 8 and prevents its silting. Transit flow dumps this sediment through a siphon 4 into the pipeline 14, 35

and in the tail section of the pipeline, they are carried to the surface of the boundary of the floor section. Adjusting the operation mode of the water distribution structures reduces to adjusting the drain calibrated orifice 12 in the bottom of the control tank 11 and the regulator 10. The irrigation time of each section depends on the filling time of the tank 11, the adjustments of the regulator 10, the areas of the calibrated orifices 12,13 pipeline 14.

Formula of the invention. The irrigation system includes irrigation pipelines with water outlets, water distribution devices in the form of a well divided by a partition into the inlet and outlet chambers, and a siphon with a vacuum tube on the bonnet communicated with a software switch, which is different in order to increase operational reliability and simplification of the design, the water distribution devices are provided with an additional chamber in communication with the inlet chamber, and an outlet is made in the partition, which informs the entrance and the siphon outlet, while the entrance chamber is filled with gravel, and the program switch is made in the form of a closed control tank communicated with an additional chamber through the regulator and having a calibrated drain hole and a side located above the entrance of the siphon vacuum tube, the end of which is located inside the tank.
