Abstract
Изобретение относитс к энергетическому машиностроению и может быть использовано в паровых турбинах дл тепловых и атомных электростанций . Изобретение позвол ет повысить надежность работы отсека ци4- линдра паровой турбины за счет снижени температуры вала вследствие снижени температуры омывающего его пара. Пар (П) протечки проходит, дросселиру сь, через зазор 6 между диафрагмой 2 и валом 7, а также через разгрузочные окна 9, при этом на выходе из последних температура его выше температуры П рабочего потока за колесом 8. Меньша часть истекающего из разгрузочных окон 9 потока П проходит через уплотнени (У) 17, причем эта дол П тем меньше, чем меньше зазор 13 в У 17. Больша часть потока П направл етс вверх, огибает кольцевой щит 11 и направл етс на смешение с рабочим потоком (Л С без потерь энергии в последнем. В результате смешени потока П с рабочим потоком температура П, попадающе- го в зазор 12, смешивающегос затем 00 The invention relates to power engineering and can be used in steam turbines for thermal and nuclear power plants. The invention makes it possible to increase the reliability of the operation of the steam turbine ci4linder compartment due to a decrease in the shaft temperature due to a decrease in the temperature of the steam washing it. Steam (P) leakage passes, throttling, through the gap 6 between the diaphragm 2 and the shaft 7, as well as through the discharge port 9, while at the outlet of the latter its temperature is higher than the temperature P of the working flow behind the wheel 8. The smaller part of the discharge box 9 flow P passes through seals (Y) 17, and this fraction P is smaller, the smaller the gap 13 in Y 17. Most of the flow P is directed upwards, envelops the annular shield 11 and is directed to mixing with the working flow (L C without energy losses in the latter. As a result of mixing the flow P with the slave Let us stream the temperature P, falling into the gap 12, mixing then 00
