Abstract

The invention relates to hydraulic engineering and can be used to block the drainage channels. The purpose of the invention is to improve the operating conditions by automatically maintaining the level of the upstream. The shutter consists of 12-, 1 cloth 1 with a platform 5, a hinge fixed on the ledge 3 of the flybet 4, a soft shell 6 located on the flybet 4 and interacting with the platform 5, and the filling system 8. System 8 consists of a tank 10 suspended from the counterweight 13 and communicating with the shell 6 through a flexible connection 16 and pipe 9. As the level of the upper bay 17 increases, the liquid from shell 6 flows into tank 10, increasing its mass. The tank 10 is lowered, which leads to a decrease in pressure in the casing 6. Cloth 1 is lowered onto the flybet 4. When the hydrostatic load of the upper pool 17 decreases on the panel 1 and the casing 6, the backflow of liquid proceeds. The cash register of the tank 10 is reduced, it rises. The pressure in the shell 6 is increased, the panel 1 rises. 1 hp f-ly, 1 ill. (L with co 4 CO

Description

The invention relates to hydraulic engineering and. can be used to block the culvert openings mainly retaining structures arranged on the canals reclamation systems.

The purpose of the invention is to improve the operating conditions by automatically maintaining the headwater level.

The drawing schematically shows a hydraulic gate.

The flex valve includes a pressure plate 1, hinged on the horizontal axis 2 mounted on the ledge 3 of the flybet A, pad 5 rigidly attached to the lower edge of the panel 1, filled with a soft shell 6, fixed under the area 5 on the flybet 4 from the side of the downstream 7 and interacting with the platform 5, and the filling system 8, connected by a pipeline 9 with the casing 6. The system 8 is fully hydrostatic

This includes a reservoir 10 suspended to the end of a cable 11 thrown through blocks 12, the other end of which is connected to a counterweight 13 located between the stops: the upper 14 and the lower 15. The lower part of the reservoir 10 communicates with the pipeline 9 through a flexible connection 16, made in bellows. If it is necessary to limit the rotation of the panel 1 towards the headwater 17, stops (not shown) can be mounted on the bulls. To drain the soft sheath 6 (for example, during repairs), it is connected to the downstream 7 by a pipeline with a crane.

Hydraulic valve works as follows.

In order to put the reservoir 10 into operation, a liquid is poured, which through the flexible connection 16 and the pipe 9 fills the casing 6. The casing 6 acts on the platform 5, which together with the cloth 1 rotates around the axis 2. At the level of the upstream 17 the required the hydrostatic load on the panel 1 is balanced by the action of the shell 6 on the pad 5, the magnitude of the influence of the shell 6 is determined by the absolute (piezometric) level of the liquid in the tank 10, which is at that moment in the extreme upper position NII.

determined by the lower limiter 15 of the counterweight 13. The total weight of the tank 10 with the liquid is less than the weight of the counterweight 13. When the required upstream level 17 is exceeded, the hydrostatic load on the bed 1 increases, the panel 1 rotates

5, which crushes the soft shell 6. The liquid from the shell 6 flows through the pipeline 9 and the flexible connection 16 into the tank 10. The total weight of the tank 10 with the liquid

exceeds the weight of the counterweight 13. The tank 10 is lowered to the lowest position defined by the upper limiter l4, which leads to a decrease in a; the absolute liquid level in

tank 10, and therefore pressure in the soft shell 6. Reducing the pressure in shell 6 leads to a decrease in the force with which it acts through the platform 5 on the panel 1, B

on the panel 1, it exceeds the force from the shell 6. The panel 1 is lowered onto the flybet 4, thereby ensuring the automatic passage of the flood flow. At the upstream level 17, the force from shell 6 to plate 1, determined by the absolute level of fluid in reservoir 10, exceeds the hydrostatic load on plate 1. Cloth 1 rises, fluid from reservoir 10 flows over flexible connection 16 and pipe 9 into the shell 6, the weight of the reservoir 10 with the liquid decreases and becomes less than the weight of the counterweight 13. The reservoir 10 rises to its highest position. The absolute liquid level in the reservoir 10 increases, which leads to an increase in pressure in the casing 6. The force from the casing 6 to the platform 5 and the panel 1 exceeds the hydrostatic load of the panel 1 rises and the water flow stops.
