SYSTEM OF END SEALS FOR STEAM TURBINE PLANT |
| 摘要 |
FIELD: sealing of steam turbine plants. SUBSTANCE: system includes at least one chamber 4 and (4<SP>1</SP>) for removal of leakage steam into vacuum bleed-off through line fitted with pressure regulating valve 7. High-temperature sealing chamber 2 is connected with vacuum bleed-off line before pressure-regulating valve 7. Vacuum bleed-off chamber 4 of low-temperature seal 1 is connected with chamber (4<SP>1</SP>) of high-temperature seal 2. Connection of chamber 4 of low-temperature seal 1 with vacuum bleed-off line is effected only through chamber (4<SP>1</SP>) of high-temperature seal 2 or through this chamber and pipeline 10 is provided with throttling member. EFFECT: reduction of temperature level of high-temperature seal; enhanced reliability and economical; efficiency of plant. 2 dwg
