Abstract

The invention relates to agriculture and is intended to automate the distribution of irrigation water in surface irrigation systems. The invention simplifies the design, increases the reliability of operation and the accuracy of controlling the flow of water. The drive of the locking member 10 of each vodovusk is filled directly in the wall of the injection pipe 1 and contains a membrane 12 with an annular control chamber 14. The control chamber 14 is formed by and fixed to the surfaces of the internal wall of the pipeline 1. In the diaphragm 12, which is fitted with a central hole, a shut-off element 10 pressed by the spring 13 is built in. The control pipeline 4 at the outlet is equipped with an adjustable choke 6.

And the provision relates to agriculture and can be used in irrigation systems for surface irrigation.

The aim of the invention is to simplify the design, to increase the reliability of operation and the accuracy of controlling the flow of water.

FIG. 1 shows the irrigation pipeline, a general view of FIG. Z - water carrier in the initial position, the section in FIG. 3 is the same, the working position.

The irrigation pipeline contains mounted water supply valves 2 with drives 3 mounted on the pressure pipeline 1, control pipeline 4 with an inlet choke 5 installed on it and an adjustable choke 6 at the exit,

Each water outlet consists of a gas pump 7, a water dispenser 7 with a water outlet 8, a housing 9 and a closure body 10 with water outlets 11,

The diaphragm actuator 3 of each water supply 2 comprises a flexible elastic membrane 12 fixed inside the pressure pipe T, made with a central hole in which the locking member 10 is preloaded with a spring 13 inserted.

The inner row of the pressure pipeline 1, the locking member 10 and the membrane 12 are formed by an annular control working chamber 14 connected by a tube 15 to the control pipeline 4,

The cavity of the quencher 7 of the last water outlet in the group is communicated by the tube 16 with the adjustable throttle 6 installed at the outlet of the control pipeline 4.

Irrigation pipeline works as follows

In the initial position (Fig. 2), all the outlets 2 are in the closed position. When water is supplied to the pressure pipe 1, provided that both adjustable throttles 5 and 6 are closed by pressure of water on the membrane 12, the locking member 10 moves to the right

and water svgpp d) prihp it (. W through in / outlets 1 1 to g tel 7, and from the last - to irrigation. In case of need to stop irrigation, throttle 5 is opened. At the same time, water from the discharge pipeline 1 enters the control pipeline 4, and through the tubes 15 into the control chamber 14 of the outlets, and exerting pressure on the membrane 12 from the side of the control ring chamber 14, causes the locking bodies 10 of the outlets 2 to slide into the case 9. The outlets 11 block off the case 9 and the irrigation stops. Spring 13 is selected with such a characteristic The fact that its compression ratio is determined by the pressure of water in the pressure pipe and the membrane elasticity, If necessary, by adjusting the orifices of the throttles 5 and 6, precisely set the required flow of water through the flow channels of the group. water discharge groups,.
