Abstract

A WATER LEVEL REGULATOR IN A DRAIN NETWORK, containing a float actuator and a shut-off element mounted on a water outlet pipe, characterized in that, in order to simplify the regulator, the shut-off element is made in the form of two pressure boards connected at an angle to each other, and the shields are connected with the float drive, and the shields of the closure member are mounted for movement along guide rails fixed to the body of the drainage pipe of the water outlet pipe, the end of which is placed in a plane parallel to bone overlying the pressure shield closure member.

The invention relates to hydraulic structures, namely, land drainage (amelioration), and is intended to automatically regulate the level of water in the drainage network.

The purpose of the invention is to simplify the controller.

FIG. 1 shows the proposed adjustment in two projections; in fig. 2 - the same section.

The groundwater level regulator consists of a water outlet pipe 1, the casing of which contains an outlet 2 made with a beveled end. To the sloping end of the outlet nozzle 2 attached plate 3 with a working hole. On the tab 3, the guides 4 and 5 are also fixed, and a sealing ring 6 is installed, ensuring the tightness of closing the regulator. A stop 7 is attached to the upper guide 4, justifying the uniform pressing of the locking member around the perimeter of the sealing ring 6. The locking member is made in the form of two pressure shields 8, rigidly connected at an angle to each other using rods 9-11. Restrictive rod

12 serves to retain the closure member in the socket formed on 1984732

by laying 3 and guides 4 and S. Petpp 13 designed a mount for a float drive (not shown). The end of the outlet nozzle 2 is placed in a plane parallel to

the plane of the shutter that overlaps it.

The regulator works both in the spillway mode and in the water supply mode.

10 Mode change is achieved by turning the controller around the longitudinal axis through an angle of 180 °.

In the water supply mode when the set level is lowered, the float drive

) 5 is lowered and the pulling force on the locking member is reduced. Under the action of hydrostatic and own weight, the locking organ is lowered. Water enters the decks of the DD. As the level is raised, the closure member rises up, closing the opening in the outlet nozzle 2 of the outlet pipe 1.

In the spillway mode when lifting

25 level above the preset, the closure member rises by the float actuator, opening a hole in the outlet nozzle 2 of the water outlet pipe 1. Water is being discharged. When lowering

By means of its own weight, the 30-level shut-off organ is lowered, the water discharge is stopped.
