Abstract

The invention relates to agriculture, in particular to drip irrigation. The purpose of the invention is to improve the quality of irrigation and system reliability. The system contains an irrigation network, in which irrigation pipelines are equipped with drip water outlets and are made with a reverse slope. The system is equipped with a block 2 irrigation current and a water current switch 13, each of which contains a housing with a partition. The irrigation current unit 2 is made with a flexible inlet nozzle equipped with a rocker with floats located in the hull sections. The water flow switch is equipped with drain pipes equipped with a rocker bolt. Water fills one of the local pipelines, irrigation pipes, droppers, and then the current switch section and the corresponding section of block 2. The rocker throws over, water enters the other section of block 2, and as the corresponding section of the block fills up, the rocker valve of its drain pipe. In this case, a low-pressure impulse is formed in the filled half of the system, the dropper valves open, a splash occurs. 6 Il.

Description

The invention relates to agriculture, namely to drip irrigation.

The purpose of the invention is to improve the quality of irrigation and system reliability.

Fig. 1 shows an irrigation system, a plan view: in Fig. 2, a drip outlet; fig.Z - switch irrigation current, general view; figure 4 is the same, view in plan; figure 5 - block irrigation current; figure 6 is the same, the view in the plan.

The irrigation system includes (Fig. 1) supply pipe 1, irrigation current unit 2, comprising body 3 (Fig. 3), partition 4, dividing body into two sections A and B, branch pipe 5 with a flexible end 6 located in the restrictor 7 on the axis of the tubular rocker arm 8, inside of which the ball 9 is placed, and at the ends of the floats 10, associated with the rocker rods 11 (Fig. 2).

(ABOUT

through pipe 12 with a water current switch 13, comprising a housing 14 with a partition dividing it into two sections C and D (Fig. 4), drain pipes 15 equipped with a beam valve 16, each of which is provided with a container 17 with a drain hole 18 and a float 19. Rocking gates are mounted on an axis 20. For reliable locking of the drain nozzles 15 of the rocker arms, they are fixed on the axis asymmetrically with a large arm loaded with a load 21.

The switch 13 of the water flow is connected with the local pipeline 22, the latter with irrigation pipes 23 equipped with droppers 24, made in the form of a tank 25 with an inlet 26, an outlet 27 and an outlet 28. Between the inlet and outlet nozzles there is a valve 29 with a double-sided stem 30, which provides alternate closure of the inlet and outlet nozzles. For air release, the ends of the irrigation pipes are provided with looses 31. The system is drained by flushing spouts 32. The system works as follows. The tubular yoke 8 with the ball 9 is inclined in one of the sections, for example B. When the system is put into operation, water from the nozzle 5 is drained into the section, then into the distribution pipeline

the bone 17 is lowered, opening the mooring bolt 16 of the outlet branch pipe 15 of section G. At the same time, water does not flow into the tubing 15, since it is located above the bottom of the housing 14, and is filled with the local pipeline 22.

Then, water fills irrigation pipelines 23 and displaces air from the network through plungers 31. There is also filling of distribution pipe 12 and raising the water level and float 10 in section B of irrigation current unit 2. The tubular rocker 8 changes its position, the ball 9 moves abruptly towards section A, the nozzle 5 switches to section L. The water through distribution pipe 12 of unit B reaches its lower part, fills the tank

17 of section B of the water flow switch, opens the rocker bolt, which leads to a short-term reverse current of the filled section G to the empty section B. At this moment, a low-pressure impulse is formed in all the inlet nozzles of section G. The outlet valve is pressed against the inlet. Water from irrigation pipelines 23 droppers out of water.

Thus, all irrigation pipelines of section G are emptied.

Claims (1)

After watering the area from the droppers of section B, the cycles are repeated until the calculated irrigation norms are supplied. Invention Formula A pulsed irrigation system comprising a water distribution network containing supply, distribution and irrigation pipelines with drip outlets and a water flow switch, which, in order to improve the quality of irrigation and reliability of the system, the irrigation pipelines are installed with a reverse inclination to the distribution pipeline, the system equipped with an irrigation current unit, made in the form of a housing, divided by a partition into sections and provided with a tubular with a movable load and floats at the ends of the bark The value is rotatable relative to the partition, the inlet flexible nozzle located in the movement limiter, freely attached to the axis of the rocker arm, and the outlet nozzles in each section, and the water flow switch is made in the form of a housing divided by the partition into two adjacent sections outlet and drain pipes, and the drain pipe - each section is equipped with a bolt with a beam actuator having a container with a drain hole on its free shoulder, which is installed with the possibility of and the switch of the inlet pipe connected to a corresponding output current irrigation pipe unit, wherein the output of the switch pipes connected with the distribution piping and drain - with its adjacent section. 31 25 23 31 / N J jl 32 J ± rJEEbI 3Cl I & W 1 23 L thirty 25 FIG.
