The invention relates to irrigation systems, namely the automatic devices of the damper flow of water for the pipeline, from which the water in the irrigation system.

The purpose of the invention is to enhance reliability of operation at high water costs.

In Fig. 1 shows an automatic tubular outlet; Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 1, the position of the cylindrical slide valve of the distributor, when the shutter is open; Fig. 4 - section b-b In Fig. 3; Fig. 5 - section G-G in Fig. 3; Fig. 6 - section b-B in Fig. 1, the position of the cylindrical slide valve of the distributor, when the th outlet contains a discharge pipe (pipe) 1, fixed in the base-2 structures, ribs 3, welded in two mutually perpendicular planes, to the ribs 3 is welded to the shutter 4 cone type, running at the expiration of the atmosphere. On the outer surface of the pipe 1 is fixed annular partition wall 5, on the outer contour of which is placed an annular movable casing 6. Partition 5 divides the sealed chamber on the left 7 and right 8 cavity. One end of the casing is rigidly attached to the nozzle 9 with the possibility of axial movement relative to the outer surface of the pipe 1. The lower reach 10 outlet is communicated through the opening 11 with the container (well) 12, which houses the float 13. Float through the rack 14 and the hinge 15 is connected to the lever 16 with the possibility of rotational movement of the valve 17. The valve 17 is attached to the vessel wall 12. On-off valve 17 is made in the form of spool 18 (tube) with a protruding shank attached to the lever 16. The valve 18 has a Central hole 19 and with two radial holes 20 and 21, and the two faces 22 and 23 for draining the water. In addition, the Central hole 19 communicates with the internal cavity 24 of the discharge pipe 1 through the tube 25 hydraulic connection. Ka is ment connected to the housing 28 of the switch, which has radial holes 29, 30, 31, 32 and the socket hole 33, the latter is adjacent the tube 25, and holes 30 and 31 are the drain and the holes 29 and 31 are connected to the tube 25 and 27. Radial holes 29, 30, 20 and 22 inch are in the same section plane (Fig. 4), respectively, the radial holes 31, 32, 21 and 23 inch are also located in the same plane of section (Fig. 5).

Automatic tubular culvert works as follows.

The pipeline 1 is under pressure, and if the level in the downstream is less than estimated, then the water from the pipe 1 enters the lower reach 10 discharge, and then in the tailrace (not shown) and simultaneously through the hole 11 passes into the well 12, where the control valve 17 and a valve 18 are in the open position. Consequently, water from the internal cavity of the tube 1 through the hydraulic tube 26 and the Central hole 33 in the cavity of the valve 18 and then through aligned holes 31 and 32 in the housing (Fig. 3, 4, 5) fills under the pressure of the internal cavity 7 sealed chamber. The ring cover 6 moves under pressure through the pipe 1 in the direction, and the nozzles 9 opens culvert cross-section of the conical shutter 4, the water flow increases. On the second tube 26 and aligned holes 29, 30, across flats 22 (Fig. 4).

Thus, water from the internal cavity 8 of the camera is draining into the atmosphere.

The water level in the downstream (N. B.) rises to the level of 34, simultaneously rises and the float 13 rotates the spool 18 via the rack 14, the hinge 15 and the lever 16 about its axis. The spool 18 in the housing 28 occupies the position shown in Fig. 6, 7, 8.

Water from the internal cavity of the pipe 1 is fed through the tube 25 into the cavity of the valve 18 and then through aligned holes 27 and 31 in the housing 28, the tube 26 fills under the pressure of the internal cavity 8 of the sealed chamber. The ring cover 6 moves along the tube 1 to the right side, moving the nozzles 9. The area of the water outlet holes of the conical shutter 4 is reduced, thereby decreasing the flow of water through the gate. Concurrently, the volume of the internal cavity 7 is reduced by the flow of water through the tube 27, aligned holes 21 and 31, through the flats 23, and drain it occurs in the atmosphere. The water level 34 drops to the settlement. To prevent possible splashing of water over the top of the shutter 4 when applying for closed piping may be installed in the floor slab (not shown).

Thus, there is osnago shutter i.e. after quenching flow preset flow is directed into the tailrace.

The advantages of the proposed device in comparison with the prototype consist in the fact that, for example, when the overshoot 300 million m3the reservoir of irrigation water only for four years by reducing unproductive passes from the reservoir in the spring and summer to postpone the full drawdown of the reservoir and save up to 58 million m3irrigation water without compromising the water supply of irrigated lands in this period.
