Title: Emergency operating valve system
Inventor: IWASAKI MASAHIRO
IPC: F16K31/122
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To enable a valve, which switches passages to a water main and to a water reservoir from one to the other through the axial movement of a valve rod in an emergency water reservoir facility, to select either self-holding or automatic restoration when operating in an emergency. SOLUTION: A water reservoir T is connected to first and fourth chambers 17a, 17d, and a water main S to second and third chambers 17b, 17c. When the water main S is under normal conditions at the required hydraulic pressure, a valve rod 14 rises as shown by the full line in the figure, and the water reservoir T is communicated with the water main S. In an emergency when the hydraulic pressure is decreased, the valve rod 14 is lowered by a spring 24, with a valve element 20a abutting to a first valve seat 19a, and with a valve element 20b leaving a second valve seat 19b and abutting to a third valve seat 19c. In such an emergency, a rocking valve 24 is closed by a control rod 40 integrated with the valve stem 14, to allow self-holding. When a valve 46 is opened, the action of a pilot valve 30 works on a valve V to allow automatic restoration.  Therefore, self-holding or automatic restoration can be selected respectively by opening or closing the valve 46.

Title: Recirculating flow rate controller for feed water pump
Inventor: TAKAHASHI NOBUYUKI
IPC: F22D5/34
Filed: 1990-07-05
Abstract: PURPOSE:To prevent the opening of a recirculating valve from a rapid increase more than necessary by a method wherein outputs from two controllers are selected according to a deviation between a suction flow rate set value and a suction flow rate of a feed water pump so that a deviation between a set value higher than a suction flow rate set value and a suction flow rate is reduced to zero. CONSTITUTION:A high value selector 17 selects an output VB from a proportional integrator 16 to output the electric output. When a flow rate QF of feed water fed to a boiler is decreased to a value lower than QU, the value of the output VB from the proportional integrator 16 is increased to a value higher than 0, whereby a recirculating valve is gradually opened from full closing. With this state, when the flow rate QF of feed water fed to the boiler is rapidly decreased and a suction flow rate Q is decreased to a value lower than QT, since a controller comprising a deviation computer 10, a limiter 11, and an integrator 12 is more rapid than a controller comprising a proportional integrator 16, VA equivalent reduction of Q is immediately outputted to the output value of the integrator 12. As a result, VA is increased to a value higher than VA, VA is selected by a high value selector 17 to effect rapid opening by means of a recirculating valve opening command V, and a suction flow rate Q is prevented from reduction to a value lower than QS.
