(54) FIXTURE OF THE HYDROTECHNICAL CONSTRUCTION D on the cavity, one of which is connected to the pipeline by means of a stop valve. The loopback seal contour of the counterstrike chamber reduces the load on the supports when the shutter is maneuvering and increases the load when the shutter is stationary. FIG. 1 shows the proposed valve, the general vis in FIG. 2 is a view A of FIG. The closure consists of an upper 1 and lower 2 pressure casings interconnected by load-carrying pipes 3, and a backpressure chamber 4 formed by the lower 2 closure sheath and the surface 4 of the closure chamber. The casing 1 has a seal 6, and the casing 2 has a main seal 7 and an additional seal 8 that controls it. -. type The main seal 7 with a small gap spans the entire perimeter of the additional seal 8, and the space between these seals is connected to the downstream short pipeline with the shut-off device 9. The shutter operates as follows. The cavity of the control chamber, which is located between the main 7 and additional 8 seals, is alternately connected to the lower pool via the locking device 9 or to the upper pool through the doyrnitelady seal 8 pressed from the deposit surface. The gate is maneuvered when the cavity between the seal MI 7 and 8 is connected to the upper side and the shutter is balanced. With a fixed gate, an additional AND seal is working, and the cavity between seals 7 and 8 connects 5 1 (; 1 IZh1P1M 6Fjef) OM, Bc.MijncTiJfo of which p-trugrujonapfloshat otshinki 2 sGGchyuvits 15-25% menno -rumped area of pressure plating 1, Unbalanced forces arise, which are perceived as lower supports. It is ensured that it is stable, without vibration of the span cable .-- Neither does the shutter work at partial opening. The dual-circuit sealing of the backpressure chamber reduces the load capacity of the mechanisms and increases the reliability of the valve. Claims of Invention Hydraulic structure shutter. including a control chamber, pressure platings, pipes, a seal contour, about and that with, with a partial shut-off valve, when the valve is partially opened, the backpressure chamber is provided with an additional contour of controlled type, section to We place it on the cavity, one of which is connected to the downstream by a pipeline with shut-off valves.
