VALVE SPECIFICATION forming part of Letters Patent No. 544,950, dated August 20, 1 89 5.
Application filed June 6, 1895. Serial No. 551,880. (No model.)
Be it known that I, ALEXANDRE BOUCHER,
Petersburg, Russia, have invented a new and useful Improvement in Steam -Valves, of which the following is a specification.
This invention relates to steam stop'valves, and has for its object to provide a steam-act-. uated valve of novel and improved construction for automatically controlling the supply of steam from a boiler or battery of boilers to an engine; and to this end it consists in the novel construction and the combination and arrangement of parts hereinafter described and pointed out in the claims following the description, reference being bad totheaccompart of thisspecification, wherein Figures 1 and 2 show the apparatus in iongitudinal sections at right angles to each other. Figs. 8 and 4 show in plan a top view and under side view of the said apparatus.
The valve proper S carries on its rod .1 a piston P of equal diameter to the said valve and moving in a cylinder Oand communicating by a cook R with passages O, O, and 0 leading, respectively, to the boiler, the con-- duit or steam-pipe, (of the engine,) or the atpistommov-ingin the cylinder 0' and in con stant communication with the boiler by means of the passage 0 The rod '1" forms a stuffing-box and out of the valve-chest, its outer end bearing against a screw V, which is used for adjusting the valve on-its seat and keeping it there in position.
The surface I) of the valve S has an area ton P, the difference between the" respective areas being equal to the sectional area of the faces have the sam'epressure of steam exerted on them there will be a greater pressure on the surface 1) than on thesurface b. ,A small discharge'cock is placed at-the bottom ofithe cylinder C. When the valveS is held against its seatby the screw V, if thelatter be loos ened and the cylinder Get the same time be placed in communication with the boiler the,
which works at the same pressure (that of,
exerting a greater force on the surface bet the piston in the directionof opening it than on the surface I) of the valve in the direction of closing it., If, on the other hand, when the l thesteam in the boiler) on the surfaces b-b',
valve is opened the cylinder 0 be placed in the surface'b of the piston P kept the valve open, the latter is closed by the pressure of the steam, whichalone continues to-acton thesurfaceb' of the valve S. Since the opening and closing of the valve S depends'on the difference of pressures exerted by the steam on the surfaces 17 and b, the rod T may be equally well placed either horizontally or vertically; but at the same time when the rod of the valve is situated vertically, the valve being beneath the piston, it will be seen that'the weight of the said valve, toget'her with its piston, tends to open it.
'When the valve S is open, the cylinder 0 should be placed in communication with the steam-conduit leading to the engine, so that the valve may close automatically in case of rupture. of the said conduit. In this case the high velocity which the steam acquires in the ately becomes less than the pressure on the surface I) of the valve, so'that the latter is closed,
f The section of the rod T, which has only to resist a strain proportional to its section and to the pressure of the steam, may be very small; andconsequently has but small influ ence on the speed of closing the valve in case of rupture of the conduit The section, however, shouldbe of sufficient size to prevent the .small ditierence of pressure which normally existsbetween the pressure in the boiler-and the'pressure in the conduit causing thcsaid valve to be closed at a wrong time; but every small sectionof the rodsufiices to prevent this.
The sectionof the passages Of and 0 should be snffi'ciently small to-preventthe steam in its escape from the cylinder C,for the prompt ,clgsing of the valve S, causing thesaid valve ico to be driven with a dangerous shock agains its seat.
The additional sliding valve D is only necessary when the valve proper is placed on a boiler forming part of a group of several boilers, so as to cause the automatic closing of the valve of a boiler which has been damaged and so to prevent the other boilers of the same group emptying by this damaged part. This sliding valve D works freely on the rod T and is kept on its seat by the steam when thelatter attempts to pass back again through the inner orifice of the valve reversing its current, which in the normal direction opens the said valve D.
For operating the screw V and the cock R keys formed by small grooved wheels may be employed, into which can take transmission chains, so that these parts may be operated equally well from a distance as near at hand.
As it is important thatthe cylinder 0 be placed in communication with the steam-conduit as soon as the said cylinder ceases to be in communication with the boiler or with the atmosphere, which is effected by operating the cock B, it is preferred 'to employ foropcrating-the said cockin place of an ordinary -key, which may be made use of in emergencies, a key worked by springs or counterweights, which automatically secures the desired movement.
What I claim is- 1. The combination with a valve casing having a steam inlet and outlet and an intermediate valve seat, of a valve adapted to close against said seat and fitted in a cylinder in constant communication with the boiler, a piston fitted in a cylinder and rigidly connected with said valve, passages connecting said cylinder with the boiler, the steam pipe of the engine and theatmosphere respectively, and a valve for controlling said passages, substantially as described.
2. The combination with a valve casing having a steam inlet and outlet and an intermediate valve seat, of a valve adapted to close against said seat and fitted in a cylinder in constant communication with the boiler, a piston fitted in a cylinder and rigidly connected with said valve, passages connecting said cylinder with the boiler, the steam pipe of the engine'and the atmosphere respccti vely, a valve for controlling said passages, and an auxiliary valve loosely arranged on the stem connecting the said valve and cylinder, and operating to seat upon the valve seat by back pressure,substantially'as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
