Abstract

1,193,800. Rotary shaft seals. WESTING- HOUSE ELECTRIC CORP. 12 Dec., 1968 [4 Jan., 1968], No. 59150/68. Heading F2B. [Also in Division F1] In a steam turbine shaft sealing arrangement comprising glands 11-16 packed with steam supplied from a high-pressure steam source via a common main conduit 18 and branch conduits 21-25 between the main conduit and the glands, a pressure reducing valve 31-35 is disposed in each of the branch conduits adjacent the glands. In the embodiment shown in which three turbines 1, 2 and 3 are mechanically connected in series, the glands 15 and 16 of turbine 3 are connected to a common branch conduit 25, the other glands being each directly connected to a branch conduit. The pressure reducing valves 31-35 are automatically controlled by gland pressure sensing lines 51-55 and a normally open manually operable valve 41-45 is connected in each branch conduit. The main conduit 18 includes a pressure relief valve 60 and is connected to the high-pressure steam source through an automatically controlled regulating valve 57 by a pressure sensing line 59. Outlet conduits 61-66 from the glands are connected either separately or collectively through a conduit 67 to a region of low pressure e.g. a condenser.
