Abstract

362,110. Fluid-actuated valves; components. AKTIEBOLAGET LJUNGSTR014IS ANGTURBIN, 17, Võstra Trõd. gardsgatan, Stockholm. Oct. 30, 1930, No. 32697. Convention date, Dec. 3, 1929. [Class 135.] Valves controlled by pilot or relay valves; casings; closure members.-A stop valve particularly adapted for use with steam turbines has the inlet conduit arranged tangentially relative to the spindle of the valve and has a diffuser shaped outlet. The inlet is at rightangles to the valve spindle and opens into a spiral-shaped space above the valve seat. The valve member 2 which is universally coupled to the valve spindle 5 has a conical seating surface 2a adapted to co-operate with a corresponding seat 3 on a rounded part of the casing. The lower part of the valve member fits the outlet with a small clearance 10 so that when a conduit 7 is opened the pressure on the annular surface 9 is substantially balanced, to complete the balance a conduit 12 is opened to connect the space above a leaky piston 14 to the outlet. The valve is opened against the action of a spring 15 by oil under pressure admitted through a conduit 21 and acting on a piston 17. A return action device may be coupled to the valve spindle at 20. The valve may be secured in the closed position by a screwed spindle 18 actuated by a hand-wheel 19 and engaging a shoulder on the valve spindle. The outlet may be divided into four branches 22, 23 elastically connected to the turbine casing.
