The invention relates to land reclamation and can be used in rice irrigation systems.

The purpose of the invention is the expansion of operational capabilities.

FIG. 1 shows a diagram of the proposed device; in fig. 2 - hydraulically controlled valve upon initial filling; in fig. 3 - the same, while maintaining the water level.

Cuttings 11 gets into regulators 1. At the same time, for all regulators (except the first), drain 19 and impulse tubes 5 and 6 are closed (Fig. 2). Water, falling into all regulators, lifts the membrane 13 and flows freely through the drain holes 10 into the checks. Simultaneously, water flows through the throttling tubes 14 into the working chambers 12 of the regulators and then into the tubes 15. Since the valves of the hydraulic relays (except the device for adjusting the second level) are closed, due to the increase in pressure between the checks 1 water level in checks with a hydraulic relay 2. For transmitting a control pulse, the regulators have holes 3, which are connected to the hydraulic relays of the subsequent regulators by pulse tubes 4-6, and the order of connection depends on the terrace of the checks (in our BEAM is received a check 3 - highest, 2 further check, the check and the check 4 1 - low). All controls are set to 5

In the working chamber 12 and the large area of the membrane 13 compared with the flow area of the inlet pipe 11, the membrane 13 closes the opening of the inlet pipe and the flow of water into the checks is stopped.

At the same time as the regulator, the drain tube is open, so the water entering the working chamber, free passage through tubes 15-16 and 19 and through valve 2, flows out to the bottom of the card irrigator, all 20 of the sphere. That is, the water through the regulator knocks are divided among themselves by rollers 7.

Level 1 controllers are a cylinder 8 which, using ribs 9 with holes 10, is attached to inlet 11. A working tube 12 is attached to cylinder 8. A membrane 13 with throttle tube is clamped between cylinder 8 and working chamber 12 14.

On the upper part of the working chamber the tube 15 is fastened, which includes a drain

drops in the check. When the check reaches a predetermined water level, and it is established by moving the tube 16 in the tube 15 with the fixation screw 17, the float 18 closes the drain tube 19. The drain from the working chamber 12 stops. By increasing the pressure in the working chamber, the membrane 13 closes the opening of the inlet 11 and the flow of water into the check is stopped. The increased pressure pulse through the pipe 16 fixed by screw 17. A float actuator is installed at the opening 23 of relay 2 through the puller 14, the float 18 of which in the upper position closes the drain pipe 19, on which the hydraulic relay 2 is installed.

The hydraulic relay 2 consists of a housing tube 4 through an opening 26 is transmitted to the working chamber 25 of the valve of the relay 2 of the next controller (in our case, check 2). Due to the pressure developed by the pressure on the membrane 28, it overcomes the force of the rod 20, which by the inlet 21 of the rod 35, rises up, is carried away by the fastener to the tube 16, and by the hole 22 - the rod 24. 31, with a drain tube 19. Hole 23 serves to connect pulse tubes. For

closing the relay valve has a stem 24. The housing 20 is connected to the working chamber 25 of the valve. For the supply of a control pulse to the working chamber there is an opening 26. The operating chamber is connected to the cover 27. A membrane 28 is clamped between the working chamber 25 and the cover 27, which

the entrance to the groove 30, fixes it. Thus, the working chamber of the regulator is connected to the drain. Water from the working chamber 12 of the regulator through the pipes 15 and 16 and 19 and through the valve of the relay 2 flows into the atmosphere, which leads to a pressure drop in the chamber. Membrane 13 rises and water begins to flow into the check. When it reaches a predetermined level of water, the float 18 overlaps with the brush 24 and the spring is loaded, the drain tube 19, which results in a gap 29. In the rod 24 there is a groove 30 with which the stopper 31 loaded with the spring 32 interacts. the flexible rod 33 with the washer 34 through the block 35, mounted on the bracket 36, the interaction of the regulator opening and the transmission of the pressure pulse through the pulse tube 5 to the next regulator, where the described cycle repeats. This cycle is repeated until the last controller is activated, i.e.

with a float 18. And on the regulated - installed in the lower check itself, the torus installed in the highest check, the relay 2 In case of a planned discharge of water from all

Constantly open, this is achieved by inserting the stopper 31 into the groove 30 and disconnecting the rod 33 from it.

The device works as follows.

During the initial water supply to the cart sprinkler, it enters regulators 1 through inlet pipes 11. At the same time, all regulators (except the first) have drain 19 and impulse tubes 5 and 6 are blocked (Fig. 2). Water, falling into all regulators, lifts the membrane 13 and flows freely through the drain holes 10 into the checks. Simultaneously, water flows through the throttle tubes 14 into the working chambers 12 of the regulators and then into the tubes 15. Since the valves of the hydraulic relays (except the first) are closed, by increasing the pressure

In the working chamber 12 and the large area of the membrane 13 compared with the flow area of the inlet pipe 11, the membrane 13 closes the opening of the inlet pipe and the flow of water into the checks is stopped.

At the same time as the regulator, the drain tube is open, so that the water entering the working chamber passes freely through the tubes 15–16 and 19 and through valve 2 flows into the atmosphere. That is, the water through the regulator enters the check. When the check reaches a predetermined water level, and it is established by moving the tube 16 in the tube 15 with the fixation screw 17, the float 18 closes the drain tube 19. The drain from the working chamber 12 stops. By increasing the pressure in the working chamber, the membrane 13 closes the opening of the inlet 11 and the flow of water into the check is stopped. The pulse of increased pressure through the pipes through the opening 23 of the relay 2 through the pulse through the opening 23 of the relay 2 through the pulse tube 4 through the opening 26 is transmitted to the working chamber 25 of the relay 2 valve of the next controller (in our case, check 2). Due to the pressure developed by the pressure on the membrane 28, it overcomes the force of the spring 29, rises upwards, is carried away by the rod 24 connected to it, while the stopper 31,

29, rises up, carries away the rod 24 connected to it, with the stopper 31,

the entrance to the groove 30, fixes it. Thus, the working chamber of the regulator is connected to the drain. Water from the working chamber 12 of the regulator through the pipes 15 and 16 and 19 and through the valve of the relay 2 flows into the atmosphere, which leads to a pressure drop in the chamber. Membrane 13 rises and water begins to flow into the check. When it reaches a predetermined water level, the float 18 closes the drain tube 19, which causes the regulator to close and transfer the pressure pulse through the impulse tube 5 to the next regulator, where the described cycle repeats. This cycle is repeated until the last controller is activated, i.e.

installed in the bottom check itself, in case of a planned discharge of water from all

checks, floats 18, dropping to the minimum value, interact with washers 34, through flexible rods 33 leads t rods 31 from grooves 30. Under the action of springs 29, the rods 24, falling down, block the inlets 21. (except the first), since

he has a flexible connection 33 sleep. When re-supplying water to the sprinkler, the cycle of the check inlet is repeated.
