The invention relates to water management and can be used to automatically regulate, for example, the flow rate or water level in irrigation canals.

The purpose of the invention is to increase the operational reliability and accuracy of regulation.

 FIG. 1 shows the device in the Closed position, general view; in fig. 2 - the same, in the Open position in FIG. 3 - normally open clap in | Open position, in FIG. 4 - in the Closed position.

The device contains a receiving capacitance-1, which is connected to the sprinkler 2. And the receiving tank 1 is placed with a water outlet pipe 3, above which is mounted a cylindrical gate 4. Above the cylindrical gate 4 is installed an outer tank 5, inside which is mounted an annular seal 6 and an annular an elastic element 7 mounted on the end of the cytriffric gate 4 with possible contact with the stop edge 8 of the guide ring seal | and 6. The ring element 7 is provided with a ring weight 9.

The device contains an executive mechanism 10, which is made in the form of a diaphragm chamber containing upper 11 and lower 12 sealed elastic tubes separated by a movable partition 13. The partition 13 is connected by a pull 14 to a cylindrical gate 4.

The device contains a hydraulic distributor 15, which is completely in the form of two rocker arms — First 16 and second 17 — kinematically unrelated to each other. The arm 16 is provided with a spring 18, providing a 03L

unstable equilibrium. The yoke 16 is connected to the float 19 of the float sensor 20 level, installed in the sprinkler 2, and interacts with two normally open valves - the first 21 and second 22, the inputs of the normally open valves 21 and 22 communicate with the annular container 5, the output of the first valve 21 communicates with the downstream 12 by the elastic tube of the actuator 10, and the outlet of the valve 22 communicates with the hydraulic actuator 23 of the locking device in contact with the rocker 17. The normally open valves 21 and 22 are made with an unconsolidated stem m, providing clearance for communicating with the atmosphere in the closed state.

The yoke 17 is connected to the float 24 of the float sensor 20 level, installed in the receiving tank. 1 and interacts with spring-loaded drain valves 25 and 26, each of which communicates with an annular container 5 and, respectively, with the above- and downstream hermetic elastic tubes 11 and 12 of the actuator 10. The yoke 17 is provided with stops 27 that act on the spring-loaded drain valves 25 and 26. The stops 27 are equipped with screws 28 adjusting the dead zone.

The normally open valve 21 and the drain valve 26 communicate with the downstream 12 elastic tube of the actuator 10 through the distribution vessel 29. The drain valve 25 communicates with the upstream elastic tube 11 of the actuator 10 through the separation vessel 30. The separation vessels 29 and 30 are filled with a chemically neutral

viscous fluid and equipped with adjustable choke holes 31.

The masses of the floats 19 and 24 are partially lightened by the springs 32 and 33, respectively, and the anchoring arm of the spring 32 can be changed, thereby achieving adjustment of the minimum and maximum water levels in the sprinkler.

The cylindrical bolt 4 has a conical surface 34.

Spring 14 is mounted on the string 14 to limit the transmitted forces.

The device works as follows.

The cylindrical gate 4 due to the conical surface 34 is statically unloaded. When the water level in the irrigator drops below the minimum (the sprinkler is turned on), the float 19, acting on the spring 18 by the rocker 16, moves it to the right extreme position. In this case, the normally open valve 22 is closed, together with the atmosphere, the hydraulic actuator 23 of the locking device. The float 24 acts on the hydraulic actuator 23 and drains the eros downward. At the same time, the stops 27 of the rocker arm 17 open the spring-loaded drain valve 25 and close the spring-loaded cream valve 26. At the same time as the normally open valve 22 closes, the normally open valve 21 opens. The control pressure of the fluid from the annular container 5 enters the separation vessel 29 and then into the lower sealed elastic tube 12. The upstream sealed elastic tube 11 at this time communicates with the atmosphere through the separation vessel 30 (spring loaded drain valve 25 is open), the cylindrical With the help of the movable partition 13 and tg 14, the mold 4 rises. With relatively large orifices of the impulse tubes and valves of the distributor 15 operating on contaminated liquid, the cylindrical gate 4 does not quickly open even with high pressure in the discharge pipe 3, as this is prevented by a chemically neutral viscous liquid flowing from separation vessel 29 into the downstream sealed elastic tube 12, and from above 0

Upon comprehending a given level in the receiving tank 1, the mass of the float L is facilitated by the buoyancy force of the liquid. Under pressure, the spring 33 of the yoke 17 approaches a horizontal position. Angle 27 terminates the action as the spring-loaded drain valve 23, by-pin npj IOK closes.

The shutter 4 is set to a stationary state. When reducing the pressure in the outlet pipe 3, the flow through its outlet nozzle decreases, reducing the water level in the receiving tank 1. The float 24 changes its position, lowering down and affecting the stop 27 of the rocker arm 17 on the drain valve 25, opens it. The upstream sealed elastic tube 1I communicates with the atmosphere through the separation vessel 30. The cylindrical closure 4 opens, increasing the flow rate to the desired value. When the float 24 rises, the Zosdey-qTBne stop 27 of the rocker arm 17 on the drain-valve 25 stops. The chamber is closed, separated from the atmosphere by the separating vessel 30 with the above sealed elastic tube 11. The cylindrical valve 4

When the level in the sprinkler 2 reaches its maximum value (the sprinkler is turned off), the float 30 1 | 9 reduces the tensile effect on the spring 32. The spring 18 moves the rocker 16 to the position corresponding to FIG. 1. In this case, the normally open valve 22 opens-, 3, together the hydraulic actuator 23 with the control pressure of the fluid. The normally open valve 21 is closed. The flow of the control pressure of the fluid into the ni- tude and the position of the sealed elastic tube 12 through the separation vessel 29 is stopped. Due to the failure of the detached slag of the normally open valve 21, the separation vessel 29 is in communication with the downstream hermetic elastic tube 12, the cylindrical closure 4 is closed. The water level drops in the receiving tank CQ 1, which would have caused the float 2i through the rocker 17 with the stop 27 to open the drain valve 25. However, this is prevented by filling the hydraulic actuator 23. The drain valve 25 remains closed and additionally opens drain valve 26. The cylindrical valve 4 with po45

eliminates the use of a cable-blocking system and reduces the distributing forces of the distributor without increasing the size of the irrigator float, resulting in increased accuracy. The presence of separation vessels with a chemically neutral liquid allows working on contaminated liquids, eliminating hydropercussions even in case of accidental air ingress into the actuator.
