Title: Control system for a steam turbine plant with re-heating
IPC: F01K7/24
Filed: 1960-07-15
Abstract: 924,379. Fluid-pressure servomotor systems. BROWN, BOVERI & CIE A.G. July 15, 1960 [July 15, 1959], No. 24694/60. Class 135. A steam turbine plant with an intermediate superheater 4 is provided with control and by-pass valves 2, 10 and 5, 13 for the high and low-pressure turbines 3, 6 and with relays 9, 16 for the control and by-pass valves respectively, the relays being controlled by a common pressure oil system 25 so that the ratio of the opening pressures for the control valves and that for the by-pass valves are varied simultaneously and in the same sense when the pressure in the system 25 is changed in dependence on a controlling characteristic. Equal steam flows are thus maintained through the two turbines and therefore through the two by-passes. A pressure oil system 26 is connected to the valves 2, 10 through throttles 26a and to valves 5, 13 through the relays 9, 16. The pressure in a line 21 which controls the valve 2 and through the relay 9 the valve 5 is varied by a governoroperated valve 8 while that in a line for the valves 10, 13 and relay 16 is varied by a bellowsoperated valve 17 responding to steam supply pressure. The system 25 may be connected to the line 21 through a throttle 27, which causes a gradual adjustment of the relays when there is a sudden change of load, or to a transmitter connected to the output of a generator 18 driven by the turbines or to a valve 33, Fig. 6, operated by a bellows 30 connected to the downstream side of the superheater 4. A second bellows 31 is coupled to the valve 30 and subjected to a pressure which may be varied manually in a central control room or through a throttle with the pressure in the line 21. Alternatively, a transmitter may be used to vary the pressure in the bellows 31 in accordance with the generator output or with a value dependent on the product of the pressures in the line 21 and in the live steam line. Each pressure relay includes a piston-actuated discharge valve 41 which keeps the ratio of the input and output pressures at a value determined by the position of a spring-loaded piston 43 which is subjected to the pressure in the system 25. The piston 43 is connected by a rack and pinion 45, 46 and a cam and follower 47, 48 to a pair of valves 51, 52 controlling the pressure beneath the piston for the valve 41.

Title: Fire extinguishing installation control valves
IPC: F16K1/22
Filed: 1975-06-10
Abstract: 1532002 Sprinkler control valve MATHER & PLATT Ltd 26 May 1976 [10 June 1975] 24859/75 Heading A5A [Also in Division F2] A control valve for fire sprinkler or deluge installations, comprises a pivotal valve disc supported by a spindle connected to an actuating lever 24, Fig. 3, which cooperates with a releasable mechanism resisting lever and thus valve disc movement. The mechanism is releasable by actuating means in the event of a predetermined condition responsive to a fire, e.g. a temperature or pressure. The actuating means in Fig. 3 comprises a weighted link 31 which when released by retraction of solenoid plunger 34, falls and pulls down pivoted catch lever 26 against action of spring 28. This releases the lever and thereby allows the valve disc to be opened by the controlled fluid pressure. The weighted link may be replaced by a weighted loop or noose which upon release from plunger 34 falls and pulls the catch lever down. In other embodiments, the catch lever is held in latching engagement with the lever 24 against the action of a spring by direct contact with a solenoid plunger (37), Fig. 4 (not shown), or with a diaphragm-actuated plunger (50), Fig. 6 (not shown), or by a fusible link device (41), Fig. 5 (not shown), comprising a pair of pivotally-connected curved links (42, 43) held in a closed loop relationship by a fusible bulb (44) which bursts when a certain temperature is reached or when a one-shot actuator (48) is operated. The lever 24 may be associated with two actuating means whereby operation of either one will permit the valve to open, Figs. 7 and 8 (not shown). Fig. 9 shows a valve having its lever 24 latched by a plunger 54 actuated by a diaphragm means 55 responsive, e.g., to downstream pressure, the lever 24 being manually re-settable to its latched position after release or automatically re-settable by a motorised actuator 56 in response to means detecting that the fire is extinguished or the temperature is normal. Preferably there is a time delay between such detection and the operation of the actuator 56. The latter may be replaced by a slowly rotating motor with limit switches, connected directly or through gears with the valve-disc spindle. A pair of valve discs may be located in series in a pipeline with their levers 24 interconnected, the discs being latched by a common single mechanism, Fig. 10 (not shown). Moreover, the pipeline space between the discs is drained when the discs are closed, so that upstream town water supply is isolated from downstream (and possibly contaminated) water. Fire fighting installations incorporating control valves of the invention are briefly described in the specification, Figs. 11 and 12 (not shown).

Abstract: 144,536. Docherty, M. Oct. 11, 1919. Spigot-and-socket screwed joints with valves; joints with yielding outer part compressed.-Relates to a hose-pipe coupling for pneumatic tools and the like characterised by a tail-piece c de. tachable from the union or coupling nut b, and having in combination with it an automatically acting valve f. The stem g of the latter is prolonged to extend through the tail piece, and at its lower end is constructed with bifurcations g<1>, g<2> which serve as guides, and while permitting movement of the valve off its seat, prevent it from falling out on uncoupling the parts. When the coupling nut b is screwed on to the usual screw coupling a or vice versa, the end of the coupling a ultimately bears against the prongs g<1>, g<2> and retains the valve in the open position. On uncoup.. ling the parts a, b the air pressure forces the valve f on to its seat and automatically prevents loss of air. The hose pipe is clamped to the nipple by two bolted grips or jaws h, i, Fig. 2, ridged on the inner side and provided with a flange l adapted to engage a groove m on the union b. Constructional modifications in the design of the valve stem are described. Instead of the bifurcations g<1>, g<2>, the stem may be drilled and a cross pin driven through the hole, or the stem may be screwed for a certain distance and a cross-piece with a nut portion screwed thereon.
