    摘要: The invention relates to a valve arrangement (1), in particular for a power plant. A housing (2) contains a shut-off valve (3) for shutting off a fluid flow, a control valve (4) for controlling the fluid flow through a housing outlet (8) and a bypass valve (5) for controlling the fluid flow through a bypass (13). This bypass (13) branches off from the housing (2) between the shut-off valve (3) and the control valve (4).

    摘要: The invention relates to a steam turbine comprising a valve arrangement for regulating the admission of live steam into the turbine consisting of two serially connected regulating valves. The two regulating valves enable a step-by-step separation of the live steam and ensure operational security in the case of a partial load operation of the turbine. Said valve arrangement is particularly suitable for steam turbines devoid of regulating steps in a fixed-pressure operation mode.

    摘要: The present invention relates to a gas-storage power plant, comprising a gas reservoir (8) in which a gas can be stored under pressure, a turbogroup (2) which has at least one turbine (3, 5), a gas-supply line (9) which leads from the gas reservoir (8) to the turbogroup (2), and a valve arrangement (12) which is arranged in the gas-supply line (9) and throttles a storage pressure (PS) applied on the inlet side to a working pressure (PA) by closed-loop and/or open-loop control. In order to improve the reliability of the valve arrangement (12), it has at least two control valves (13, 14) arranged in series. A leading first control valve (13) throttles the storage pressure (PS) applied on the inlet side to an intermediate pressure (PZ) by closed-loop or open-loop control. A subsequent second control valve (14) throttles the pressure (PZ) applied on the inlet side to the working pressure (PA) by closed-loop control.

    摘要: A method for treatment of skin includes topical application of a composition containing a therapeutically effective amount of a 1,3-beta-glucan ether derivative. Such application effectively provides treatment and/or prophylaxis of various skin-related problems, such as neurodermatitis and psoriasis, and reduces the evidence of aging by minimizing wrinkles. In an advantageous embodiment, the glucan ether derivative is present in the composition in a range of concentration of about 0.002% to about 8% by weight. In another embodiment the glucan ether derivative is advantageously carboxymethyl glucan sodium salt.

    摘要: This actuating drive (1) for a control valve (2) has a control circuit which sets the actuating drive (1) to correspond with a specified required value from an overriding installation control system. It has, in addition, a main piston (6) sliding in a main cylinder (5) with a drive volume (7), on one side of the main piston (6), which can be acted on in a controlled manner by oil under pressure and has a plate valve (17) fitted upstream of the drive volume (7).The intention is to create an actuating drive, for a control valve, whose dynamic behavior can be improved by relatively simple means. This is achieved by the plate valve (17) being provided with a separate reservoir volume, connected to a drain appliance, for the oil emerging from the plate valve (17).

    摘要: A high temperature actuated steam valve is disclosed that has a connector extending between the casing of the valve and its actuator. The connector can include two spacers made of materials each with a different hot strength wherein the first spacer, fixed adjacent the casing, has a higher hot strength that the second spacer, which is fixed adjacent to the actuator.
