(57) Abstract:

Usage: for liquid supply with a constant flow from the tank with the changing level. The essence of the invention: capacity installed movable pipe with a float mounted on the intake pipe. On the exhaust pipe is installed with the possibility of moving the elastic headstall with which the outlet is configured for a given flow rate. When the change in the liquid level of the tank, the pipe moves with the float that provides a constant differential /h and a steady flow of water. 2 Il.

The invention relates to agriculture and can be used for drip irrigation of plants.

Known device for supplying water into the drip irrigation system plant comprising a tank, a device raising and lowering it, inlet and outlet water communication [1].

Disadvantages installation are unstable degree of precision regulation of water consumption and design complexity.

Known outlet containing a curved pipe with movable inlet and outlet nozzles, the first of which is omitted in the supply tank and is equipped with a float and the second elastic tip [2].

The purpose of the invention is the improvement of the quality of work by ensuring the accuracy of the issuance of a preset flow rate and simplify the design.

This is achieved by the elastic cap is installed with the possibility of axial movement relative to the pipe, curved pipe relative to the feed tank vertically.

In Fig. 1 shows a diagram of the outlet of Fig. 2 - same view in the plan.

The device consists of a tank 1 (Fig.1), lead communications 2, the float 3, a U-shaped pipe 4, one end attached to the float 3, a rubber tube 5 of the blower 6 is mounted on the other end of the pipe 4.

For purification of water in the drip irrigation system, the tank 1 is divided into three isolated one from the other sections a, B, C partitions 7, (Fig.2) each of which are mounted filters 8.

Section And connected with the inlet water communication 2, provided with a float valve 9 serving to maintain a constant liquid level in the tank 1.

The device operates as follows.

Water flows from the inlet 2 via the communication valve 9 in section a of the tank 1, which is the settling of suspended particles. Then the water, 8 section B arrives in the next section Century. When filled with water section In the float 3 pipeline 4 POPs up. Then by moving the rubber tube 5 install the specified water flow, i.e. the value of h. The specified flow rate is determined experimentally. Pear 6 suck water into the pipe 4 and the pipe 5. From the tube 5 water flows into the drip irrigation system plant.

During operation the water flow remains constant and does not depend on the water level in the tank 1, because the value of h remains constant. Therefore, the constant value h provides precise water flow from the tank 1.

Regulation of water discharge is performed by changing the value of h by moving the rubber tube 5 through the pipeline 4.

OUTLET containing a curved pipe with movable inlet and outlet nozzles, the first of which is omitted in the supply tank and is equipped with a float and the second elastic wall, characterized in that, to improve quality by ensuring the accuracy of the issuance of a preset flow rate and simplify the design, the elastic cap is installed with the possibility of axial movement relative to the pipe, curved pipe relative to the feed tank vertically.
