.AL'V'f-.j RICKSECKER, J R., OF CHICAGO,- ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS. TO AJAX VALVE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.
vALvE.
To all whom 'it may concern:
Be it known that I, ALvA C. RICKSECKER, Jr., a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented new and useful Improvements in Valves, of which the follow' ing is a specification, reference being fhad to the accompanying drawings, forming apart thereof.
The purpose of this invention is to provide an im roved construction of valve in which the disk shall be adapted to accommo date itself to the seat by virtue of the elastic- -ity and iiexibility of the disk, and which shall, notwithstanding such elasticity and flexibility, be adapted to sustain and resist high pressure when seated.
It consists of the' features of construction set'out in the claims.
In the drawings Figure 1 is an axial section of a globe valve embodying my invention. Fig. 2 is a detail section of the lvalve and its seat, showing the valve disk itself by its flexibility to a seat not perfectlyl circular which is encountered either inside or outside such annulus. This annulus is dished or flaring and seats after the manner of a hood or cap on the valve seat. .f
In Fig. 1, my invention is shown applied to a valve of theusual construction as to the body, 1, and in which the seat, 2,7is adapted to be encountered by the disk, either on the inner or on the outer side. The valve disk is made preferably of sheet metal struck up or spun into desired form. A The valve disk,-
v 3, has its seating ortion constituting a peripheral annulust e entire disk being in the form of a cup or ca'p with a central aperture in the bottom by means offwhich it is adapted to pass on to the disk holder or terminal Specieation of Letters Patent. Appiiemgniea may e, 190s. serial No. 259,149.
element, 4, of the stem, said holder having a threaded terminal portion, 4, which sses through the central a erture of thdi and having also an annu ar latform or s110111- der, 4", surrounding said central threaded portion, said platform or shoulder being an nularly corrugated as shown, the corru as tions being somewhat acute, so that the disk when clamped on` the shoulder against Suchacute corrugations is slightl impressedor indented by the latter and t ere is thereb produced a fluid-ti ht joint between the dis u and the holder in e annular area about -:the central terminal, 4, on to which there is screwed the binding' nut, 5. A gasket., 6, ma be inter osed .between the binding nut an the annu ar portion of the disk against which the nut operates to clamp it. tothe corrugated seat. Such gasket operates in addition to the corrugated. pilatfollli.A or shoulder to make a iluid-itightbiiit which prevents assa e of' fluid aroun nal, 491. ll'he isk-holder, 4, is preferably A'connected to the threaded stem, 7, so as to be readily detachable andto permit the stem to rotate without rotatiiA the holder and disk. T hat is to say, the holder is swiveled to the stem, The mode of attachment 'illustrated is familiar, the stem, 7, havin v an enlargement or ange, 7a, at the en which Patented nea-an, isos. y
the termii enga s the under-cut slot, 4, of the holder,
the s ot being extended to one 'side so' that the head maybe entered on the stem.
The more usual method of using` a-va'lve disk of the construction shown is so that it encounters the seat on the outer side of the latter and the inner side of the Seating annulus of the disk; but'whether used in the formof an exteriorl or interiorly seating itself to a seat which may not be perfectly circular, such accommodation resulting from the flexibility of the annulus in a v'plane transverse to its axis. In addition to accommodating itself to the seat by reason of its iexibility, such annular disk 4has soin apacity for accommodating itself by reason vof its elastic extensibility and oompressibility that is to say, when it seats exteriorly it will stretch slightly circumferentally in 01.?-
.der to reach the seat at all oints, but when applied interiorly vit .Slightly ccm,-
`device, it has the qua ity of-accoinmodating pressed, yielding elastically to accommodate the seit.
In Fig. 2, the valve disk is shown ada ted A to be reversed so as to present either si e to the corresponding side of the valve seat. The seating annulus of the disk is flaring and radially curved, and the seat is sloped, both at;V the inner and the outer side, so that the disk may be mounted on the holder either with vthe concave inner -s'ide or the convex outer -side facing the seat. In said Fig. 2, the latter adjustment is represented,
the seat being encountered en its inner sloping side by the outer convex side of the an- -nulus.
' forcing fiange or bead 3x formed at the periphery of the annular disk, proj'ecting outwardto strengthen it against the possibility of rupture when forced too severely u on the seat.' This diskzsornewhat diminis es both the iexibility and the extensibility of the eriphery, but still leaves those qualil" ties su ciently present to adapt the disk to perform all the functions above described. In Figs. 1 and 2, there is illustrated also another feature relating to the form of the nut for securing the disk to the holder and the fluid-wayl within the valve seat. This nut, 5, is substantially cylindrical, except as modified for a special purpose, but is modied as shown in Figs. 1 and 2 for a specic purpose hereinafter explained. It is provided with notches, 5a, 5a, constituting practically a diametric slot to engage a device in the nature of a screw driver or` a straight key, as will be readily understood without further description. A nut of-this general character with a slight modification may be made to serve a secondary purpose of graduating the opening of the valve, or making a valve which has the'effect of a .very slow taper -at its seat without the danger of becoming wedged unreleasably in its seat. This modification is illustrated in Figs. 1 and 2, in which the nut has an enlargement back of the notched or 'slotted' en d, as seen at 5d, which is slightlytapered and adapted" to tit the correspondingly slightly tapered interior surface of the fluid-way through the Valve seat'. The val e disk will be Sshaped and proportioned wi h respect to the point 'at which it encounters the `seat, so that such encounter will occur before the slightly tapered portion, 5, of the nut is actually i 4seated on said wall of the Huid-way, and so that the valve disk may be forced on to the seat suiiiciently to cause it lto accommodate itself to the latter in case the seat is not per= fectly circular, and may be stretched orl compressed slightlyv for the purpose 0f such accommodation, ,without wedging the tapered portion of the nut in the,luidway, the intention being that mere contact of the two slightly tapered surfaces shall be effected by the time the disk has been forced sulficiently to accommodate itself perfectly to the l seat. In opening a valve of this construction, it will be seen that the Huid-wayA will be unclosed very gradually, according to the gradual taper of the nut and fluid-way, until said enlarged and sli htly tapered portion,
5d, of the nutis comp etely withdrawn from ,v the corresponding lportion of the Huid-way,
and that, during that portion of the opening movement, the valve disk will be withdrawing directly from the seat and the valve will be opened widely by very short movement of the valve after that point is reached, thus giving the advantage of a very gradually opening valve at the commencing of the opening movement, with the advantage of a very rapidly opening valve at a subsequent part of the movement. It will be seen that this construction of the nut and fluid-way is available whichever Way the disk `is mounted,-that is, whether as in Fig. 1,'seat'- ing on the concave side exterior to the seat, or as in Fig. 2, seating onthe convex ,side Within .the seat.
