  • Patent number: 5088341
    Abstract: An engaging lever lock for rotor turning gear in a steam turbine includes a selectable lock that is disposed to hold the lever at its engaged position and control circuitry for activating the selectable lock. With a first embodiment, the selectable lock includes an electromagnet. On the other hand, with a second embodiment, the selectable lock includes a plunger-pin arrangement that is activated by a solenoid to extend into a hole formed in the lever, and is biased toward a retracted position away from the hole by a spring which is disposed around the pin between the plunger and the solenoid.

  • Patent number: 4917570
    Abstract: An axial thrust limiting system for a steam turbine including a rotor having a shaft, the turbine containing a plurality of chambers each defining a pressure zone containing a fluid which, during operation of the turbine, is at a pressure which influences the axial thrust load on the shaft, the turbine being constructed such that at least during rapid shut down a pressure differential can develop between two of the chambers to create an excessive axial thrust load on the shaft. The axial thrust limiting system includes controllable valve connected in a fluid flow path between the two chambers, and valve operating components connected for operating the valves during rapid shut down of the turbine in order to reduce the pressure differential between the two chambers.

  • Patent number: 4852850
    Abstract: A steam bypass valve system for a steam turbine. The system provides a supplemental hydraulic seating force to a fast acting bypass valve after the valve plug is positioned against the valve seat with a spring force. The system also provides for quick hydraulic relief in order to retain the fast opening characteristics of a single acting hydraulic valve.

  • Patent number: 4766932
    Abstract: A steam flow control valve for controlling large fluid flow rates, the valve having a reduced response to vibrational excitations experienced during throttling. A valve stem extending outward from the valve body and connected in the valve to a valve plug is guided by a substantially rigid cylindrical bushing extending substantially through the valve body. The bushing has an inner surface for guiding movement of the valve stem and an outer surface for guiding movement of the valve plug. The plug includes an inner annular guide ring about an upper edge for sliding along the outer surface of the bushing and limiting transverse motion.

  • Patent number: 3938541
    Abstract: A shaft seal for a check valve having a shaft rotatably disposed within a valve housing. The shaft seal is disposed within a recess defined within the interior of the valve housing between a bushing member and the shaft. Disposition of the seal within the recess permits accumulation of foreign matter precipitate to occur without deleterious clogging of the clearances between the shaft and the bushing, thus permitting free rotational movement of the shaft. A plurality of sharp-edged grooves disposed on the surface of the shaft provide a flow path for guiding the foreign matter precipitate into the recess. A flushing fluid opening is provided within the valve housing to permit introduction of a flushing fluid into the body recess.
