Abstract

The invention relates to hydraulic structures and can be used as an automatic outlet. The aim of the invention is to increase the reliability of the controller. The level controller contains a water inlet pipe 1, an elastic valve 2, the cavity of which is connected to the pipeline 4, a float valve 5 mounted on one of the pipelines 4. Included in the controller is a fixed shield 7 installed on the axis of rotation 8 on which the water tank is installed the wall 6, the inclusion of the cavity 10 formed by the water wall 6, the shield 7 and the flexible cover 9 fixed between them, makes it possible to increase the reliability of the regulator. 2 Il. 9 CO CD oo m 4 co. / S

Description

The invention relates to hydraulic structures and. It can be used as an automatic outflow, as an autoregulator of the lower or upstream level on tubular structures of irrigation systems.

The purpose of the invention is to increase the sensitivity of the controller.

FIG. 1 and 2 shows the regulator

The level regulator contains a water outlet pipe 1 installed between the upper and the tails, a cylindrical elastic shutter 2 fixed on the water outlet pipe 1, on the tank surface of which the annular hollow element 3 is fixed, the cavity of which is connected to the upper and lower tails of the pipelines 4, on the outlet It has a float valve 5 installed in its pipe. The regulator contains a water wall: wall 6, a fixed shield 7, in the lower part of which there is a horizontal axis 8 of rotation on which the water wall is installed. 6 ENKA, The perimeter stilling walls 6 and 7 is reinforced flexible shield shell 9. stilling wall 6, shield-7 and flexible casing 9 define a cavity 10 of variable volume J posts with the conduit 4.

The regulator works as follows.

At the estimated water level in the downstream, the float valve 5 closes the outlet of the pipe 4. When the pressure in the cavity of the annular hollow element 3 increases, the capacity of the structure decreases. In turn, pressure also increases in cavity 10. The pressure decrease in cavity 10 leads to movement of water wall 6 towards the flow. Movement of the water wall 6 ISSUE 1T before making contact with the loose end of gate 2, which eliminates unproductive water losses.

When lowering the water level in the downstream float valve 5 from

it collapses together with the downstream pipeline 4. In the cavity of the annular hollow element 3, the pressure yMeHbcja-, and due to the pressure from the side of the water outlet pipe 1, the shutter opens. At the same time, the pressure in the cavity 10 also decreases, and due to the pressure of the water leaving the flow through the shutter, the moving water wall 6 turns around axis 8 and is placed on schlt 7. Water begins to flow into the downstream. This eliminates the possibility of rubbing the shell against the water wall. In order to actively energize energy, the shield 7 is positioned at an angle to the axis of the exit stream.

The advantage of the proposed regulator is to increase the reliability of the elements subject to abrasion, to exclude unproductive water losses, to actively quench the energy of the stream, preventing erosion in the downstream,

Invention formula

A level regulator in the pools of hydraulic structures, containing a water outlet pipe, is installed between the upper and lower pools, mounted on the outlet pipe of a vertical elastic valve, on the side surface of which an annular hollow element is fixed, the cavity of which is connected to the upper and lower tail pipelines the outlet nozzle of which has a float valve, a water wall, with which the loose end of the elastic shutter is connected to the contact, is about the same and is designed so that reliability of the regulator., it contains a fixed shield. in the lower part of which a horizontal axis of rotation is placed, on which a water wall is installed, along the perimeter of which and around the perimeter of the shield a flexible shell is fixed with the formation of a cavity of variable volume communicated with the pipeline.
