THROTTLE VALVE.
Application filed July 5, 1924. Serial No. 724,463.
My invention relates to improvements in a lower seating flange 16, which rests on a throttle valves having two seats.
' One object of the invention is to construct the valve so that it will close against both 4seats at all times.
i A further object of the invention is to construct the valve so that one portion will yield to allow both parts thereof to seat themselves properly.
A still further object of the invention is to locate the valve in the smoke box of a locomotive between the superheater head and the pipes leading to the cylinder. f
In the accompanying drawings:
Fig. 1 is a sectional view on the line'l-l, Fig. .2, illustrating my improved throttle valve;
Fig. 2 is a side view illustrating the location ofthe throttle valve in the smoke box of a locomotive; and
Fig. 3 is a sectional plan view on the line 3 3, Fig. 1, illustrating the passages in the.
valve.
Referring Vto the drawings, 1 is the shell of the boiler.
which are attached the flue tubes. 3 is the smoke stack. 4 is a deflecting plate, directly back of the smoke stack, which, is used when oil is the fuel. The head 5 of the superheater is located in the smoke box 6 of the boilerY in front of the tube sheet 2 and has circulating tubes 7 which extend into the iiue tubes in the ordinary manner'. Mounted on the portion 8 of the superheater is 'a casing 9, which encloses the throttle valve 10. A rock ,shaft 11 is actuated in any suitable manner from the cab of the locomotive and has an arm 12 connected by a link 13 to the throttle valve 10.
ln the present instance, the link 13 is connected to a small valve 14, which has a limited movement to allow steam to enter tangential channels 15 in the body of the valve 10 to permit a certain amount of steam to enter the cylinders-while the locomotive is Vdrifting. These passages are formed in the tangential ribs of the valve 10, kas shown clearly in Fig. 3. In some cases, this valve may be omitted, in which instance the link 13 is connected directly to the valve 10. `The tangential ribs connect the spaced innerV andA 'outer portions of the valve as shown in Fig. 3, and prevent distortion from unequal eX- pansion and contraction. The valve 10 has 2 is the front tube sheet to,
Y 21. The ring slides on the upper portion 24 of the valve. In this portion' is a ring 25, which has a working fit against the ring 20.
The ring` 2() is connected to a hub 26 by ribs 27. Located in a recess inthe hub is a spiral spring 28, which is seated in the bottom of the recess and against a nut 29 that is screwed onto the threaded portion 30 of a projection of the valve. The ring 20 is so proportioned in regard to the seating flange 16 that, when the valve is closed, the ring 2O will seat itself, first on its seat 21 and then the spring will yield to allow thel seating flange 16 to come in contact with the seat 17, thereby making a tight joint at the upper and lower portions yof the valve.- This construction insures a tight fit of the valve on both seats of the casing under all conditions.
While my invention is shown as adapted to be located in the smoke boX of a locomovenient place, without departing from the essential features of the invent-ion.
I claim:
1. The combination of a' valve casing having two seats; a'throttle yvalve located in the casing and having a seating flange for one of said seats; va centrally located portion projecting from the valve and threaded at its end; a recessed slidable hub mounted on the said portion; a spring located within the recess; av nut on the threaded portion against which the spring bears; arms projecting from the hub; and a seating ring carried by the arms and arranged to close yieldingly against the other seat of the casing.
2. The combination of a valve casing having two seats; a valve mounted in the casing and having a' seating flange and a yieldingly seated ring for the respective seats; a series of tangential passages in the valve between the seating portions; a small valve Controlling the flow of Steam through these passages; and an operating link connected to the VLilve so that the small Valve will be 5 operated inadvance of the main valve.
3. The veonnhinfztion of a Valve casing having tWo seats; a Valve mounted in the casing and having spaced innei1 and outer portions and having a seating flange and a yieidingly seated ring for the respective 10 seats;V and tangential ribs connecting said inner and outer portions of the Valve.
