Description

Изобретение относитс  к энергетическим газотурбинным установкам и может быть использовано в газотурбинных установках с жидкостными замкнутыми системами охлаждени  газовых турбинThis invention relates to gas turbine power plants and can be used in gas turbine plants with liquid closed gas turbine cooling systems.

Известна система замкнутого жидкостного охлаждени  газовой турбины, у которой, с целью защиты от перегрева , отвод охлаждающей воды из ротора выполнен через торцы рабочих лопаток в коллектор статора 1.A known system of closed liquid cooling of a gas turbine, in which, in order to protect against overheating, the cooling water is drained from the rotor through the ends of the blades into the stator collector 1.

Однако в случае повреждени  одного из элементов системы значительное количество воды испар етс  впрйтбчной части турбины и выбрасываетс  в атмосферу, что снижает КПД цикла.However, in the event of damage to one of the elements of the system, a significant amount of water is evaporated in the turbine part of the turbine and released into the atmosphere, which reduces the efficiency of the cycle.

Известна также система замкнутого жидкостного охлаждени ,  вл юща с  ближайшим техническимрешением к изобретению, содержаща  замкнутый контур охлаждающей жидкости с подключенным к нему трубопроводом подпйтки , св занным с питательным бачком , и установленный на магистрали подачи топлива в камеру сгорани  запорный клапан 2 .A closed liquid cooling system is also known, which, with the closest technical resolution of the invention, contains a closed coolant circuit with a piping pipe connected to it connected to a feed tank and a check valve 2 installed on the supply line to the combustion chamber.

Однако, в такой системе надежност ее защиты от перегрева ограничиваетс  емкостью бака при разгерметизации системы в результате износа или. повреждени  каких-либо элементов конструкции турбины, поскольку VBeV личение расхода охладител  не вли ет на подачу топлива через запорный клапан, установленный на магистрали подачи- топлива, в камеру сгорани ,However, in such a system, the reliability of its protection against overheating is limited by the capacity of the tank during depressurization of the system as a result of wear or. damage to any elements of the turbine design, since the VBeV cooling flow rate does not affect the flow of fuel through a shut-off valve installed on the fuel supply line to the combustion chamber,

Цель изобретени  - повышение на- The purpose of the invention is to increase the

0 дежности защиты турбины от перегрева.0 reliability of turbine overheating protection.

Это достигаетс  тем,что в питательном бачке установлен дозирующиЙ клапан с контактом, воздействующим на за порный клапан.This is achieved by the fact that a metering valve is installed in the feed tank with a contact acting on the porous valve.

В питательном бачке 2 установлен дозирующий клапан 0 connected with nutrient (tank 2, and installed on line 3 of the fuel supply to the combustion chamber 4 shut-off valve 5. In the supply tank 2, a metering valve is installed
