.Apparatus for Regulating Turbines Driven by Live and ExhaustI Steam, of which the following is a specification.
The invention relates to means for regulating the speed 'of an-exhaust steam turbine having a part operated by live steam.
According to the invent-ion the steam inl let organs' are controlled by an oil relay, the valve-face of which is divided so that both parts thereof can be adjusted independentof each other according tothe variations of pressure in the exhaust' steam pipe.
The objects of the invention are to render the stresses on the governor gear independent of the variations of pressure of the eX- haust steam, to cause more or less live steam to come into action according as the pressure in the exhaust steam pipe, alters and to simultaneously close the exhaust steam valve in order thus to regulate the amount of energy supplied to the engine.
In the drawing one construction of the new oil relay valve gearingpis shown by Way of example, Figurek 1 representing the connection between the oil relay and the governor of the turbine in side elevation, Fig. 2 the oil relay itself in the 'vertical section on a larger scale, Fig. 3 is a sectional view through the oil-relay on line A-B of Fig. 2. Fig. 4 is a section through the device taken on line C-D of Fig. 3, showing the adjusting device for the slidevalve sections of the oil-relay and its connection with the regulating piston of the' heat accumulator. Fig/5 is a lperspective view on an enlarged scale of the adjustingcone for the slide-valves with the sections of the valvev in operative position. Fig. 6 is a detail sectional View of a portion of the adjusting-cone and adjoining portions' of the valve-sections shown in Fig. 5 in position. Fig. 7 is a section through the head of the oil-relay, showing the mechanism for regulating the valves to admit steam under different pressures. Fig. 8 is a diagrammatic view partly in section of the device in use with a steam turbine, with its various connections. v i
' 'Referring more particularly to Fig. 8, 1 1s the auxiliary low-pressure turbine, and 2 is the adjacently disposed high-pressure steam turbine- 3 indicates the turbine shaft, upon which, in front of the two turbines, is fastened a piston 4 to relieve the turbines of the end thrust of the shaft. At 5 is shown a heat accumulator of the well known Rateau type, which has the form of a boiler. Into this heat accumulator t-he (not shown) Whichvis used to perform any kind of work, is conducted through the conduit 6, and from thence passes through outlet-pipe 7 and valve turbine 1. The inlet-valve 8 for the exhauststeam is connected to the piston 9, which is subjected on one side to the action of a spring 10, and on the other to the action of oil-pressure, which is conducted thereto the inlet ,pipe for the boiler-steam, through which the latterA is conducted to the highpressure turbine through the valve 12. The valve 12 is connected to a piston 13, which, in the same manner as shown in connection with the piston 9, is subjected to the action of a springl on one side, and on the other side to the action of oil pressure, which is fed through the channel III. yUpon the shaft 3 is secured in any suitable manner, a spiral pump 15, by means of which the pressure in the oil is generated for the oilpasses through the channel I from thepressure-pump 15 Vto the oil-relay, which is shown on an enlarged scale in Fig. 2. A governor j which controls the valve ai of the oil-relay is driven by the turbine-shaft `3 by means of bevelI gear connections.v The channel 7c is a connection between the heat accumulator and the regulator which is best shown in Figs. 3 and 4, and by means of which the pressure in the heat accumulator is communicated to the piston z'.
The valve --dof the oil relay is adjusted in the usual manner from the collar -a of the governor 'bthrough the lever -caccording to the load on. the ture'xhaust steam issuing from a steam engine 8 into the low-pressure through the channel' II. At.. 11 is indicated4 relay.. The oil is kept in circulation, andv :".Fs I 1:015415." s i f bine. Said valve -dhas' two operating erns the passage of the oil under pressure to the auxiliary engine for operating the exhaust steam valve, while the edge -fgoverns the supply vof oil to the engine of the live steam valve. The oil under pressure passes to the'relay through the channel I and flows being suitablythrottled by setscrews toward both edges -eand When these edges are open the oil under pressure flows in the direction ofthe 'arrows through the channel IV. If on thev other hand the edge for example -eof the valve +dcuts oil the Iressure of the oil, the pressure of oil in t e channel II will increase and the exhaust steam valve will be raised. When the oil is throttled by the edge -fthe oil pressure will increase in the channel III, whereupon the live steam valve will rise. Now in order to adapt this operation of theoil relay for turbines having two pressure stages, the valvel face is divided into two movable parts -g- -k-. Each part is adjustably independent of the other and the adjustment of both parts is rendered dependent from the variations 'of pressure in the exhaust steam pipe, which can be done in various ways.
In Fig. 3 the device for independently adjusting the two-'parts of the valve-face is shown in horizontal section.' This however is only one construction chosen as an example. The top of the piston 4I- -is exposed to the pressure of the exhaust steam from the heat-accumulator with which its cylinder is connected by means of the pipe A spring 2 acts on the underside of this piston ifso that the pressure of the heat accumulator is balanced by the tension of the spring in every position of the piston. The upper part of the pistonrod -fmff is -provided with teeth n in which engage the teeth -o on the circumference of the adjusting cone -;0-. The said` adjusting cone p4 has two screw# j only move longitudinally. The adjusting cone is prevented from moving longitudi-V nally by an annular rib fw- The springs -sand tserve to press the parts -gand -hof the valve-face on the screw-surfaces -gand -rof the adjusting cone -p-. As soon as there is insuiiicient exhaust steam, the pressure in the pipe `--kand over the piston f1- will sink. The spring -Z will therefore lraise the piston v5- and by the teeth Jmof the rod --/n,- and the teeth o'- of the adjusting cone, said cone will be so turned face sliding thereonwill ,approach `reachI other.A 'As a lconsequence the edge -ewhich does not alt-er its positionLwill un@ cover the opening in the part -g,- lso that oil under pressure will escape at that`point i and consequently the exhaust steam valve will close. The edge -f-in the part -kfon the other hand will close the opening in the latter,thus throttle the passage of the oil and cause the live steam valve to open. In order to provide for the admission of live steam at differentA ressures ofthe ex? haust steam (for examp e at 1.0 1.05 or 1.1 atmospheres), the part 4hoi the valveface is adapted to be lmoved up and-down by. a hand-wheel fwon the upper. The hand-wheel u is secured-to the boxin e by means of a groove and feather, and said boxing surroundsthe spindle of the valve v section h. Thespindle is secured to the boxing z by means of a spline, so that by turning the hand-wheel u, the boxing z and with it, the slide-valve Asection h will be rotated. In the boxing e is located at regular intervals a series of recesses in which the catchbolt engages, so that the slide-valve section k, may be set at diiferent positions.
In constructing the apparatus it is immaterial whether a single valve is used and this valve is provided with both operative chosen, or whether the said operative edges are provided on two or more different valves. The essential feature of the oilrelay is the division of the valve-face andv the adjustment of the same by the pressure in the heat-accumulator independent of the gear of the governor.
What I claim and desire to secure by Letters Patent of the United States is 1. The described apparatus for regulating exhaust steam turbines having a part operated by live steam, comprising in combination a governor, an oil valve adapted to be. adjusted by said governor and having a valve-face divided into two separate parts and means to adjust said parts in accordance with the pressure of the 'exhaust steam in the heat-accumulator, substantially as and for the purpose set forth.
2. In combination with an apparatus for regulating the speed of a turbine operated by both live and exhaust steam, of an oil valve having two operative edges and a separate slide as valve-face for each operative edge of said valve, substantially as and for the purpose set forth.
3. In an apparatus for-regulating the speed of a turbine operated by both live and exhaust steam, the combination of an oil valve having a valve-face divided into two parts; a cone adapted to be rotated without moving longitudinally and having two screw surfaces adapted to act on the parte of said valve-face so as tolcause them to approach or recede from each other simulta neously, a piston regulator, a heat accumulator adapted to operate said piston regulator7 and mechanism connecting said piston regulator with said valve, substantially as and for the purpose set forth.
`n testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
