FIELD: power industry.

SUBSTANCE: hydraulic gateway control system comprises a sealing mechanism, a door opening and closing system, a pressure equalizing valve and their drives mounted for each gateway door. Hydraulic cylinders are used as power devices. The hydraulic cylinders are connected by control sources and by means of hydraulic lines with a pressure source in the form of a hydroelectric station. The manual mode control devices for the nonhermetic and hermetic zones contain manual pumps connected to manual hydraulic distributors. The structure of the system additionally includes electromagnetic hydraulic distributors, roller hydraulic distributors. Each of the roller hydraulic distributors is connected in these zones with a suitable hydraulic cylinder to open, seal the door or open the pressure equalizing valve, with the possibility of switching them depending on the version. In parallel to each roller hydraulic distributor on the side of the nonhermetic zone, a ball valve is installed. On the roller hydraulic distributors connected to the hydraulic cylinders for opening the gateway doors on the side of the nonhermetic and hermetic zones, check valves are installed.

EFFECT: invention allows reliable operation of the gateway control system under the influence of dynamic loads.
