Claims (3)

1. Устройство подвода уплотняющего пара в цилиндр паровой турбины, включающее узел отбора пара из ПКУ ЦВД, соединительные трубопроводы, снабженные дроссельной шайбой, байпасными линиями, обратными клапанами, узлом ввода пара в ПКУ ЦСД, отличающееся тем, что устройство дополнительно снабжают узлом отбора пара с более низкой, чем у рабочего тела в первой ступени ЦСД, температурой, расположенным непосредственно за первым отсеком обоймы уплотнений ПКУ ЦВД и соединенным с трубопроводом, который снабжен дроссельным регулятором-распределителем расхода, делящим общий поток отбора пара на две части, с соотношением расходов не менее 1:3, а также с профилированной приемной камерой, расположенной между ПКУ и первой ступенью ротора ЦСД, которая обеспечивает направленность входящего в камеру потока пара и его распределение на две равные по расходу части, одна из которых направляется непосредственно в ПКУ ЦСД, а другая - в секцию диафрагменных уплотнений второй ступени ротора ЦСД.1. A device for supplying sealing steam to the cylinder of a steam turbine, including a steam extraction unit from the control panel of the central heating cylinder, connecting pipes equipped with a throttle washer, bypass lines, non-return valves, a steam input assembly to the control panel of the central control valve, characterized in that the device is additionally equipped with a steam extraction assembly with a lower temperature than that of the working fluid in the first stage of the central cylinder, located directly behind the first compartment of the seal casing of the control panel of the central cylinder and connected to the pipeline, which is equipped with a throttle control valve flow rate, dividing the total steam extraction stream into two parts, with a flow ratio of at least 1: 3, as well as with a profiled receiving chamber located between the control panel and the first stage of the DPS rotor, which ensures the directivity of the steam stream entering the chamber and its distribution into two equal according to the flow rate of the part, one of which is sent directly to the control panel of the central cylinder and the other to the diaphragm seal section of the second stage of the central cylinder rotor. 2. Устройство подвода уплотняющего пара по п.1, отличающееся тем, что большую часть потока после дроссельного регулятора-распределителя направляют в приемную профилированную камеру ПКУ ЦСД, а меньшую часть - в линию сброса пара в проточную часть ЦВД и/или в подогреватель пара высокого давления.2. The device for supplying sealing steam according to claim 1, characterized in that most of the flow after the throttle control valve-distributor is directed to the receiving profiled chamber of the control and control system, and the smaller part is sent to the steam discharge line to the flow part of the high-pressure cylinder and / or to the high-pressure steam heater pressure. 3. Устройство подвода уплотняющего пара по пп.1 и 2, отличающееся тем, что поток пара, поступающий в приемную профилированную камеру ПКУ ЦСД одновременно через разгрузочные отверстия диска ротора первой ступени ЦСД, направляют в секцию диафрагменных уплотнений второй ступени ЦСД, при этом устройство позволяет автоматически поддерживать заданные соотношения расходов отбираемого с узла отбора ПКУ ЦВД и распределяемых далее потоков пара.3. The device for supplying sealing steam according to claims 1 and 2, characterized in that the steam flow entering the receiving profiled chamber of the control panel of the central cylinder at the same time through the discharge openings of the rotor disk of the first stage of the cylinder cylinder is directed to the diaphragm section of the second stage of the cylinder cylinder, and the device allows automatically maintain the specified ratio of costs taken from the selection node of the control panel of the high-pressure cylinder and the steam flows distributed further.
