Abstract

The invention relates to hydraulic engineering and can be used to automatically control the level of water on land reclamation systems. The purpose of the invention is to improve performance. The regulator contains partition walls 1 with overflow windows 2, a water-filled elastic tank 3, rigidly fixed at the bottom. The elastic container 3 freely moves along the guide posts 5. In the downstream, there is a valve 6 with a float sensor 8. Control valve 10 with a pressure device 12 is located between the partitioning shields 1 and the sprinkler pushes the pressure device 12 with a wheel. The water from the elastic container 3 is discharged and the capacity is lowered. The pressure device then returns to its original position with the help of the control valve 10, and the tank 3 is filled with water, blocking the spillway 2. If there is not enough water for irrigation in the downstream, the float valve releases water from the elastic tank 3. 3 sludge.

The invention relates to hydraulic engineering and can be used to automatically control the level of water on land reclamation systems.

The purpose of the invention is to improve performance.

FIG. 1 shows the regulator, a general view; in fig. 2 - valve regulating the water level in the downstream; in fig. 3 - spring-loaded control valve with a pressure device.

The water level regulator contains blocking shields 1 with overflow windows 2, water-filled elastic tank 3, the bottom of which is rigidly fixed. The elastic tank 3 with the rings 4 fixed on it freely moves along the guide posts 5. The controller has a valve 6 connected through the rod 7 to the float sensor 8 of the lower pool, which is connected by tube 9 with the elastic tank 3. The position of the float sensor 8 allows open or close the discharge of water from the elastic container 3. A spring-loaded control valve 10 is located between the partition walls 1, which is mechanically connected with the pressure device 12 through the rod 11, the latter is open through f or closing the water discharge from the elastic container 3, which provides easy access to water intake sprinkler from the tail water in the pond. The valve 10 is connected by a tube 13 with an elastic tank 3, which is hydraulically connected via a tube 14 to the upper reach.

The regulator works as follows.

In the initial position, the elastic tank 3, under the action of its own mass and the mass of water from above, is in the folded down position, the water freely pours out from the overflow window 2 into the lower pool. As the downstream is filled, the float sensor 8 floats up and the valve 6 blocks the discharge of water from the elastic tank 3. The elastic tank 3 with the rings 4 fixed on it is filled with water through a tube 14 connected to the upper pool and moves

along the guide posts 5 upwards, thereby blocking the spillway windows 2. When the sprinkler approaches the controller, it pushes its wheel on the pressure device 12, which presses the rod 11, lowers the spring-loaded control valve 10, and drops water through the tube 13 beef The elastic container 3 with the rings 4 fixed on it along the guide posts 5 is lowered down.

When the float of the sprinkler approaches the overflow window 2, they are fully open and it passes unhindered. When the regulator passes, the sprinkler moves down from the pressure device 12, as a result, the control valve 10 returns to its original position, the water discharge stops, the tank 3 is filled, shutting off the drain window 2

If there is not enough irrigation water in the downstream, then the float sensor 8 of valve 6 is in the lower position, having released water from the elastic tank 3, thus the tank 3 does not block the overflow window 2, and water is supplied to the downstream. When the refill fill is over, the float sensor 8 rises to the upper position and blocks the discharge of water from the elastic tank 3, it begins to fill through the tube 14, blocking the overflow window 2. Similarly, the process repeats when the sprinkler moves back.
