  • ASSEMBLY HAVING A SPRING-LOADED TANDEM CONTROL VALVE
    Publication number: 20040154665
    Abstract: The fitting, in particular a safety valve, operates according to the relief principle or according to the loading principle. The fitting is opened and closed by a plurality of control parts. The control parts are connected in series in the control line of the fitting and are each actuated by a control valve. The control parts open the fitting only when all the control parts are in a position which opens the fitting. The fitting closes as soon as even only one of the control parts is in a position which closes the fitting.

  • REACTOR PRESSURE VESSEL AND PROCESS FOR TEMPERATURE EQUALIZATION IN A REACTOR PRESSURE VESSEL
    Publication number: 20030202627
    Abstract: A reactor pressure vessel with an upper support plate, in which an equalization opening is provided as a bypass is described. A process for temperature equalization between an upper dome chamber above a support plate and a lower chamber below it is described. It is proposed that the cross section of the equalization opening be variable as a function of the temperature, so that the flow of medium between the upper dome chamber and the lower chamber is varied as a function of the temperature.

  • Damped valve
    Patent number: 6073651
    Abstract: A valve includes a device for shutting off a valve interior. The shutoff device is positioned by a piston which is guided in a cylinder and forms a first chamber and a second chamber in the cylinder. The second chamber communicates with the valve interior through a throttle path, so that the shutoff device is movable in a damped manner in both closing and opening directions.

  • Steam power station
    Patent number: 6011826
    Abstract: A steam power station, in particular a nuclear power station, includes a steam conduit leading through a wall and forming a fixed point with the wall for the introduction of forces and moments. A main valve is connected to the steam conduit at the fixed point, without a high-pressure pipe being interposed. Satellite valves, which have smaller nominal widths than the main valve, are fastened to the housing of the main valve, without a high-pressure pipe being interposed. At least one additional valve has a housing fastened to the housing of a satellite valve, without a high-pressure pipe being interposed and without any support.
