Abstract

The invention relates to agriculture and can be used for irrigation by sprinkling and drip method of agricultural crops. The aim of the invention is to increase reliability. The irrigation system consists of a pumping unit 1, a main pipeline 2, distribution pipelines 3 and 4 with valves 5 and 6. Irrigation pipes 7 are connected to distribution pipes 3 and 4 through non-return valves 14. Droppers 8 and sprinklers 9 are installed on irrigation pipelines 7. Droppers 8 and sprinklers 9 have switches made in the form of direct and reverse flow valves. During operation of the irrigation system, water is supplied from the main pipeline alternately to the distribution pipelines. Additional devices or droppers are included in the operation. Supplying the system with an additional distribution pipe 4 and making the dropper 8 and additional devices 9 in the form of direct and reverse flow valves provide water to the irrigation pipelines on each side and prevents the accumulation of debris. 2 Il. i (o

FIG.

In order for the system to work in drip irrigation mode, valves 6 must be open and valves 5 must be closed. When the pump unit 1 is turned on (or the automatic switching of valves 5 and 6 from the sprinkling mode to the drip irrigation mode), water flows through the main pipeline 2 to the distribution pipes 4 and from them through its check valves 14

The invention relates to agriculture and can be used for irrigation by sprinkling and drip method of agricultural crops.

The aim of the invention is to increase the reliability of operation.

FIG. 1 shows the general, and the scheme of the irrigation system; in fig. 2 - execution of direct and reverse current valves.

The irrigation system includes a pumping,

unit 1, main pipeline 2, to irrigation pipelines 7 (in the diagram - distribution pipelines 3 and 4 from back to right to left). The flow of water closes with the slots 5 and 6, the irrigation pipelines 7 switches on the inlet nozzles 13 with droppers 8 and the sprinkler apparatus 9 and opens the ratami 9.switches on the inlet nozzles 12,

At the ends of the distribution pipelines, the check valves of the distributors 3 and 4 are closed, a self-flushing pipe 3 is installed and enters the plugs 10. The switches are made in the dropper 8 and moisten the soil, in the form of direct and reverse current,

for example, a ball-B can be used.

a small flag 11. At the same time, all self-cleaning plugs 10 run in all cycles. 12 droppers 8 connections are located in one 20 opens from the distribution pipe to the irrigation pipe 7 and wires 3 or 4 (as well as from the inlet connections 13 of the sprinklers) - the pouring pipelines 7) sludge, hydrobionts 9 - to the opposite. You and other debris in the form of water are used. The irrigation pipelines 7 are connected, the pensions are removed through it to the outside. When the distribution pipelines 3 and 4 reach the nominal pressure in the network, the check valves 14.

The irrigation system consists, for example, of three sites of irrigation A, B and C.

Irrigation system works as follows.

Claims (1)

To ensure the sprinkling mode on the -, Q side, the network does not have conditions for areas A, B and C of the valve system 5, the accumulator is open, and valve 6 is closed. When the pumping unit 1 is turned on, the water is supplied. The formula of the invention is supplied by a pressure through the main pipeline 2 to the distribution pipeline. The irrigation system includes water 3 and out of them through the return valves, the distribution 14 enters the irrigation pipelines and connected with them one 7 (in the diagram - left to right). At this end, the irrigation pipelines from the drops of the water flow open the switches with sprinklers and sprinklers from the inlet pipes 13 of the sprinkling devices, characterized in that the rats 9, which were out of order to increase reliability, were in a neutral position , and is supplied with additional distributor covers switches on the inlet pipelines connected to 12 droppers 8. Then the water is supplied with inlet pipelines, and the switches go off and the sprinkler Stages 9, sprinklers and sprinklers are filled with them and irrigate the crown of the plants. They are in the form of direct and reverse valves. The check valves on the distribution side of the current, while the irrigation pipelines 4 do not allow the water to be connected to the distribution pipes to supply water to them. through the check valves. the self-flushing plug 10 is closed; the one-time flow of water through it ensures reliable operation of the switches. Since water in areas A, B and C of the system is supplied from one to another, so that the system works in drip irrigation mode, valves 6 must be open and valves 5 closed. When the pump unit 1 is turned on (or the automatic switching of valves 5 and 6 from the sprinkling mode to the drip irrigation mode), water flows through the main pipeline 2 to the distribution pipes 4 and from them through its check valves 14 , in irrigation pipelines 7 (in the diagram - from right to left). The flow of water closes the switches on the inlet nozzles of 13 sprinklers 9 and opens the switches on the inlet nozzles 12, the penny is removed through it outside. Upon reaching the nominal head in the network  On the other hand, there are no conditions for the accumulation of litter in the network. Claims of the Invention The irrigation system, which includes a pumping unit, a mainline, distribution and one-way irrigation pipelines with droplets and sprinklers with switches, differs in that that, in order to increase reliability, the system is equipped with additional distribution pipes connected to flow pipelines, and the switches of droppers and sprinklers are made in the form of direct valves and brother-on current, while irrigation pipelines are connected to distribution pipelines through check valves. the self-flushing plug 10 is closed; the one-time flow of water through it ensures reliable operation of the switches. Since the water in areas A, B and C of the system is supplied from one to another
