UNITED STATES PATENT OFFICE.
GEORGE IE.A DEMPLER, OF PITTSIBUlifGrIEI,` PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO'PROTECTED SEAT VALVE COMPANY, OF PITTSBURGH, PENN- SYLVANIA, A CORPORATION OF PENNSYLVANIA VALVE.
Specification of Letters Patent.
Patented July 12, 1921.
To all whom t may concern:
Be it known that I, GEORGE P. DEMPLER residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Valves, of which improvements the following isa specification.
My invention relates to improvements in valves, and particularly to improvements in the valve shown and described in United States Letters Patent No. 1,267,365, granted May 28, 1918, to Charles A. Borchert and Michael G. ONeil.
In the accompanying drawings, Figure I is a view in vertical section of a globe valve structure, the valve parts of which constitute an embodiment of my invention. These valve parts are shown in closed position. Fig. II is a similar view of the valve parts alone, and in this figure these parts are shown in open position. Fig. III is a view in horizontal section, on the plane indicated at III-III, Fig. II.
The valve casing may be of any desired form suitable to the intended service. The drawings show, (by way of example) a globe valve casing 1, having an inlet 2 and an outlet 3, and a partition 4 through which is formed a port 5. It will be understood that the direction of flow defined, and indicated upon the drawing by arrows, might equally well be in opposite direction.
The valve parts in which my invention particularly resides consist essentially of a sleeve member 6 and a closure member 7, movable one respecting the other and by such relative movement performing the valve function. These two members are provided with suitably disposed coperating surfaces 9 and .10 wluch 41n the range of relative movement mentioned alternately separate and make close contact, one upon another. Either member may be movable, but referably it is the closure member 7 whicli is moved, as shown. Accordingly, sleeve member 6 is secured in the partition 4 and closure member 7 is carried upon a lon itudinally movable stem 8.
Fig. I shows this surface inwardly and downwardly inclined; but, if the position of the structure lwere inverted, the disposition of this surface would be the reverse; its position is always such as to avoid any collection of sediment upon it. This is a matter sufficiently well known to engineers in the art. The companion closure member 7 has, as has been said, a corresponding and coperating surface 10. Nothing further need be said of its arrangement and disposition, than that in these respects it is the complement of thesurface of the sleeve member, already defined.
The closure member is further provided with a fiange 11 which overlies and, in the relative movement of these parts, telescopes upon the exterior surface of sleeve member 6, projecting beyond the surface 10 of the closure member.4 And, finally, the closure member 7 is provided with a guide arranged within the sleeve member 6, and conveniently taking the form of a spider 13". These parts are so proportioned that flange 11 is less, and spider 13a greater in longitudinal extent than the range of movement of parts 6 and 7, one relatively to the other. The s ider by its structure while serving as a gui e permits the passage of fluid through the opened valve.
There is in the particular construction of the parts already defined a further feature of invention. I have said of closure member 7 that it is carried by the operating -stem 8, and that it is provided with the valve face 10 and with the telescoping flange 11. Stem 8 is provided with the terminal enlargement 14 having the usual spherical face, to sustain the thrust of serviceand to permit of more accurate seating of the valve. Engagement of the closure member with this enlarged end ofthe operating stem 8 is effected by forming the portion from which the fiange 11 extends and the portion upon which the valve face 10 is formed in two parts, and screw-threading these two parts one upon another, constituting them the two members of a cage lwhich secures itself upon the'enlar ed head 14 of the stem 8. Thus I have a t ree-part structure of simplest form capable of ready application an furthermore, the part which bears the valve seat, the part subject to greatest wear, is readily separable and replaceable as need arises.
The fundamental advantages of my improved construction now described include that of the Borchert and ONeil patent already alluded to: The valve surfaces are protected from abrasion at the time when abrasive action would otherwise be at maximum--the time when the two valve sur faces are separated at but a narrow interval. Furthermore, when the valve surfaces are separated and while iange 11 still overlaps sleeve member 6, there will 'still be a sufficient leakage iow, not to abrade, but to sweep the lower valve surface clean of sediment. This latter feature of course becomes important when the valve is in the act of closing.l A further particular advantage of my lconstruction lies in making the flange 11 of less length than the range of valve movement, and in relying on the internal spider 13 to serve as a guide. By virtue of this the whole structure may be reduced in `over-all length, and economy effected accordingly. he structural simplification already alluded to, and consisting in the three separable parts, valve 7, valve-stem 8, and flange l1, makes for the same end, economy of space, affording at the same time the advantages of a separable valve and one which automatically accommodates itself in seating to any irregularity of alinement.
I claim as my invention:
A' valve structure comprising a sleeve they are secured tothe head of the valve stem, substantially as described.
In testimony whereof I have hereunto set my hand.
