    摘要: In an actuating drive for valves, the stroke motion of the servo piston has to be transmitted to the return sleeve in the control block, so that this results in that hydraulic feedback which restores the equilibrium at the servo piston. By means of a lever or a single-point mounting, this same stroke motion is directly transmitted to a pin attached in an eccentric position relative to the center axis of the return sleeve and transmitted from this pin to the return sleeve adjoining thereunder.

    摘要: In a spring suspension of an actuating piston, essentially consisting of a spring plate, a control spring acting on the spring plate and a nut as connection between actuating piston and spring plate, an intermediate underlay (5) is arranged between spring plate (2) and nut (4). The supporting surfaces of the intermediate underlay (5) with respect to the spring plate (2) and the nut (4) are formed by several mutually offset rolling elements (6a, 6b).

    摘要: A steam turbine (10), especially in the form of a double-flow low-pressure steam turbine, includes a rotor (11) which is rotatably mounted around an axis (21) and which is concentrically enclosed with a spacing by an inner casing (13), forming annular steam passages (28, 29), and which has a multiplicity of rotor blades (12) which project into the steam passages (28, 29), wherein the inner casing (13) supports a multiplicity of stator blades (12) which project into the steam passages (28, 29) and which, for feeding steam to the steam passages (28, 29), has an inlet duct (15) which is directed around the axis (21) and tapers in the flow cross section. With such a steam turbine, the production is simplified by the inner casing (13) being formed as a welded construction, in which blade carriers (14), which delimit the steam passages (28, 29) and are produced as cast parts, are welded to additional forged or rolled steel elements (20) for fastening the stator blades (12′).

    摘要: The object of the invention is to increase the efficiency of a low-pressure steam turbine connected to a condenser and to reduce its cost of manufacture. According to the invention this is achieved when the dividing plane (8) of the top and bottom part (6, 7) of the outer casing (1) of the low-pressure steam turbine lies at the level of the axis (9) of the turbine rotor (4) and the concrete foundation (14) reaches up to the dividing plane (8). Both the bottom part (7) of the outer casing (1) and the bearing points (10) of the turbine rotor (4) are secured in the concrete foundation (14). The outer casing (1) is designed to be open at least on one side at right angles to and horizontally to the axis (9) of the turbine rotor (4). A condenser (16) is attached to each lateral opening (17) in the outer casing (1). The top part (6) of the outer casing (1) consists of an assembly hood (19) and, for each condenser (16), a frame part (20) connected to the latter and the bottom part (7) by retention of self substance or in a non-positive manner. The assembly hood (19) is connected to both the bottom part (7) of the outer casing (1) and each frame part (20) in a non-positive or positive-locking manner, one frame part (20) each being arranged between a condenser (16) and the assembly hood (19).

    摘要: In a quick-action flap, in which opening occurs by means of hydraulic actuation and closing can be initiated by a spring, two independent systems are provided, namely a servo system. (1) and a flap disk system (2), which are connected to one another via a coupling (1a, 2a). The coupling itself has, between the coupling part (1a) on the servo side and the coupling part (2a) on the flap disk system side, a free-wheel which makes it possible for the forces occurring upon impact of the flap disk (14) on the seating ring in the flap casing (9) to be divided up in accordance with the kinetic energy of the moving masses of each system (1, 2). The free-wheel thus distributes the stressing over two successive impacts, whereby the stress in the lever (12) of the flap disk (14) is reduced by approximately one half. A hydraulic brake in the servo system (1) ensures that the closing speed of the flap disk is kept constant approximately in the last third of the closing process.
