VALVE.
SPECIFICATION forming part of Letters Patent No. 618,709, dated January 31, 1899.
Application led September 29, 1898. Serial No. 692,222. (No model.)
To all whom it may concern:
Be it known that I, CHARLES E. MORELAND, residing at Oeredo, in the county of Vayne and State of West Virginia, have invented a new and Improved Valve, of which the following is a specification.
This invention, which relates to improvements in globe-valves, comprehends generally the organization of parts constituting the complete valve and in its more specific nature embodies a novel construction of valve-seat and valve engaging the same, combined in such manner as to provide for a ready removal and renewal of the packing members of the seat and valve.
The main object of my invention is to provide a valve of this character having the several parts so disposed and connected that the entire structure of valve can be economically produced and the valve, the seat, and their packing members rendered the more effective in their uses and the construction desirable in that the parts can be quickly and conveniently exposed for inspection and the renewal of packing or other members.
NVith these objects in view the invention comprehends certain details of construction and peculiar combination of parts, such as will be first described, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in Which- Figure lis a vertical section of my improved Valve, the valve being in its open position. Fig.v2 is a similar view showing the valve closed down on its seat. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 is a horizontal section on the line L i of Fig. l. Fig. 5 is a detail view of the valve-spindle and the valve. Fig. G is a detail view of one of the metallic packing-rings. Fig. 7 is a detail view of the valve-seat, packing-ring, and the retainingeeap. Fig. S is an enlarged detail view of a portion of the valve-seat, its packing-ring, and the retaining-cap and Fig. 9 illustrates a modiiied means for holding an elastic packing on the valve, hereinafter particularly referred to.
In the drawings, in which like numerals indicate like parts in all the flgures,1 indicates the valve-casing, which may have the conventional contour.
2 designates the induction and 3 the eduction way, which ways are disposed on the diametrically opposite ends of the casing.
The diaphragm 4 has a central horizontal seat 5 surrounding the orifice 5, which seat has an annular depression 5b, the inner wall of which extends upwardly to form a flange 5C,which iiange has internal threads, as shown.
6 indicates the seat-packing for the end of the metallic ring of a width to snugly iit the depression 5l and of such thickness that when fitted in place its upper face will project slightly above the upper face of the annular flange 5C. While the said ring 6 may be fitted vsufficiently tight to remain on the seat depression b without further holding means, yet I prefer, on the score of positively and properly holding the ring G on its seat, to provide a detachable cap-piece in the end of the ring 7, havin ga central opening of a size equal the orifice 5, a pendent eXteriorly-threaded liange 7 n, adapted to engage the threaded shank 5c, an annular flange 7b, arranged to project over the head of the liange 5c and lap the inner edge of the ring 6, and a non-circular or nut portion 7C, as clearly shown in Fig. 7.
The valve-casing has its top formed with an opening of a larger diameter than the valveseat surrounded by a vertical exteriorlythreaded iiange S.
So far as described it will be readily seen that the packing-ring G can be quickly and conveniently removed from or replaced on the seat whenever the shank or neck 9 of the valve is removed. Furthermore, by extending the flange 5C, as shown, the said ring 6 i's held from direct steam impact as the steam charges through the orifices 5a, and by providing a detachable cap-piece 7 of the construction shown the said packingring 6 is not alone securely and positively held to its seat under all conditions, but is also the more thoroughly protected and held from dislodgment by steam orfluid pressure.
T-he shank member 9, which is externally threaded to engage the lian ges 8 of the valvecasing, has a centrally-threaded Way 9 for the externallythreaded valve-controlling IOO Lil
clavos spindle 10, its upper end terminating in a stuffing-box 10 for the non-threaded portion 10b of the spindle, said shank being also externally threaded at the upper end to receive the gland 11.
12 indicates the valve-spindle handle. The detachable shank portion of the casing has an npwarally-extending seat 9C, in which the disk 12, forming a part of the valve, has vertical play, said disk being substantially the diameter of the said seat Sie. The disk 12 has a centrally-proj ectin g stem 12?,whieh plays and is guided in a vertical recess 10(l on the lower end of the spindle 10.
13 indicates a packing-ring, which is adapted to be detaehably secured to the under face of the disk 1 2, and when such ring is of metal it is swaged between a pair of concentric annular flanges 12b, held pendent 'from the disk 2, said disk I3 being of a diameter the same as ring G.
vFrom the foregoing it will be readily seen that when steam on and the spindle 10 adjusted to an open position the valve-disk will be held up, shown in Fig. 1., it being guided. by its stem moving in the recess of the spindle 1() and its edges engaging the seat QC of the shank.
lt is manifest that by protecting the packing-ring (i, as described, the only efleet the steam-pressure can have thereon will be in the natu re ol a downward force, which serves to aid in keeping such ring (j on its seat. As the steam-pressure will hold the valve up in the seat 9 under ordinary conditions and as the lower end of the spindle 10 is recessed it follows that in closing the valve the spindle can be lowered until its bottom end bears against the disk 12, thereby providing for a solid abutting pressure on the valve by moving it down accurately against its seat, it being obvious that the rings f5 and 13 engage when the valve is closed.
Nhen it is desired to use elastic packingrings instead oi` metallic rings, the ring 13 is secu red to the valve-disk in the manner shown in Fig. il, by reference to which it will be observed that the inner one of the concentric pendent flanges of the valve-disk is extern ally threaded and adapted to receive a wedgecap ll-,the perimeter of which is wed ge-shaped and adapted, when the cap is screwed home, to clamp the ring 13 against the outer flange 15, said cap-piece having a non-circular hub 17, whereby it can be readily screwed in place.
It will be observed by arranging the several parts as described and shown access can be prickly had to the valve and the parts adjusted, the worn rings removed7 and new rings properly placed by any one.
Having thus described my invention, what l claim, and desire to secure by Letters Patent, is-
1. As an improvement in globe-valves the combination with a slidable valve having a disk portion provided with a pendent packing-ring; of the casing having its diaphragm formed with an annular depression surrounding the steam-passage, the inner wall of such depression forming a vertical protectingflange, said flange having an internallythreaded portion; a packing-ring detachably held in the said depression; a detachable open cap member having a threaded portion to engage tlie threaded flange, and an annular horizontal member adapted to lap and en gage the valve-seat packing-ring, substantially as shown and for the purposes described.
2. 1n a globe-valve of the character described; a slidable valve and means for moving it against the valve-seat, said valve having a disk provided with concentric pendent ri ms, one of such ri ms being threaded; an elastie packing-ring adapted to be fitted between the rims,and a securing-cap havinga threaded portion to engage the threaded rim; a wedge portion to engage and compress the packing against the non-threaded rim, and a wrenchreceiving head, for the purposes described.
The hereinbefore described improved globe-valve; comprising in combination; a valve-casin g having its diaphragm formed with an integral valve-seat provided with an annular depression, the inner wall of the 4depression being extended to produce a vertical protecting-flange; said flange being of less height than the thickness 0f the packingring, and having internal threads; a packingring detachably fitted in the depression; an open cap-piece having a threaded shank to en gage the aforesaid threaded flange and provided with an annular member t0 engage the upper face of the packing-ring, and a noneircular or wrench-receiving head; a shankpieee detachably fitted in the casing, provided with an annular seat or hollow chamber in its lower edge and a vertically-threaded bore; a threaded spindle portion operated in said boreand having an elongated recess in its lower end; and a valve consisting of a disk having a shank tting the recess in the spindle and having concentric pendent rings, said disk being of a size to snugly play in the hollow cham ber of the casing-shank; and a packing-ring detachably held between said disk valves, substantially as shown and described.
