Description
F. L. WHITE NUV. 7, 1939.
VALVE Filed June 3, 1939 Attorneys atented Nov. 7, 1939 VALVE Fitzhugh L. White, South Norfolk, Va.
Application June 3, 1939, Serial No. 277,317
2 Claims.
My invention relates to improvements in drain valves of the general type disclosed in my United States Letters Patent No. 2,136,163, dated November 8, 1938, and over which the instant valve is designed as an improvement.
The invention is designed with the particular purpose in View of providing, as compared With the valve of my aforesaid patent, a structurally simplified and more highly efiicient drain valve which may be utilized as a combination fitting and drain valve in either pressure, or vacuum, lines and in practically any situation.
To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my improved valve has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claims appended hereto.
In said drawing:
Figure l is a View in side elevation of the preferred embodiment of my improved valve.
Figure 2 is a view in end elevation looking at one end of the Valve.
Figure 3 is a View in transverse section taken on the line 33 of Figure 1 looking in the direction indicated by the arrows.
Figure 1 is a similar view taken on the line 4-i of Figure 1 looking in the direction indicated by the arrows.
Figure 5 is a view in longitudinal section taken on the line 5-5 of Figure 1 looking in the direction of the arrows, and
Figure 6 is a view in transverse section taken on the line 6-6 of Figure 5 looking in the direction of the arrows.
Referring to the drawing by numerals, the illustrating embodiment of my improved valve comprises a tubular casing i provided in the transverse center thereof with a radial external flange 2 having a hexagonal face for providing a wrench hold. The casing l tapers on opposite sides of the flange 2 toward opposite ends of said casing and is externally threaded, as at 3, for turning into a pipe line (not shown) and functioning as a fitting therein. Adjacent one end thereof, said casing l is provided with an internal annular flange i functioning as a stop shoulder for a purpose presently apparent. outwardly of the flange t, the bore 5 of the casing l is provided with an enlarged end, as at 6, for a purpose presently seen.
The bore 5 of the casing 1 contains an elongated valve stem l longer than said casing i so as to extend beyond opposite ends of the latter and endwise slidable in said bore, said stem having a tail end 8 slidable in the flange i and a disclike enlarged head end 9 forming a valve member movable inwardly of the casing i to seat against the adjacent end of the latter and close said end. The head end 9 is slightly smaller in diameter than the seat end of the casing l for clearance in the line to which said end of the casing is connected. Valve stem '1 is longitudinally fluted to within a short distance of the head end 9 to provide the same with radial ribs l0 and transversely concaved channeled sides H and is of substantially the same diameter as the internal diameter of the flange 4 to find a bearing at its tail end on said flange l, with the following exception. Adjacent the head end 9 of said stem, said ribs it are provided with radially extended and transversely enlarged ends l2 for cooperating with the bore 5 to provide a bearing for the stem i adjacent the head end thereof. A helical spring l3 sleeved onto the stem 1 intermediate the flange 3 and the enlarged ends 12 urges said stem in a direction to space the head end 9 from its described seat and thus maintain the valve open. At the tail end 8, the ribs ill are notched, as at Hi, to receive a split keeper ring it: larger in diameter than said stem and coacting under the urge of the spring l3 with the flange 4 to establish the opening position of the head end 9, said ring being accommodated in the enlarged end 6 of the bore 5. The ends ii of the ribs It may be undercut, as at it, for cooperation with the related end of the spring I3 to hold the latter in proper position.
As will be apparent, if the seat-forming end of the valve casing l is turned into the end of a pressure line, not shown, and the other end of said casing into a drain line, under a given pressure in the pressure line the valve stem 1 will be moved in opposition to the tension exerted by the spring 13 in a direction to seat the head end 9 of said stem and close the valve. On the other hand, under a drop in pressure in said pressure line the valve stem 1 will be urged by the spring IS in a direction to open the valve, the opening position of the stem being established by the described coaction of the rings it with the flange i. In the open position of the valve, the pressure line is drained by way of the channeled sides ll of the valve stem 7 as will be clear. If, on the other hand, the end of the casing l opposite to the seat-forming end is turned into a suction line, under a given suction, the valve stem l will be moved to close the valve in the same manner as described. In the absence of a degree of suction sufficient to close the valve, said suction line will be drained, the spring l3 maintaining the valve open.
The foregoing Will, it is believed, suffice to impart a clear understanding of my invention without further explanation.
Manifestly the invention, as described, is susceptible of modification Without departing from the inventive concept and right is herein reserved to such modifications as fall Within the scope of the subjoined claims.
What I claim is:
1. A valve of the class described comprising a tubular casing externally threaded upon opposite sides of its transverse center for turning into a pipeline and having an internal radial flange therein adjacent one end thereof, a longitudinally fluted elongated valve stem movable in said casing endwise and having a tail end slidable in said flange, and an enlarged disc-like head end adapted under movement of said stem in one direction to seat against the opposite end of said casing and close the same, said stem being radially enlarged adjacent said head end thereof for hearing against the inner wall of the casing, a
-' helical spring sleeved onto said stem between said flange and enlarged end of the stem and urging the latter in the opposite direction, and a member detachably mounted on the tail end of the stem and coacting with said flange to limit movement of the stem in said opposite direction, said member comprising a split resilient ring, and said stem being notched to detachably seat said ring therein.
2. A valve of the class described comprising a tubular casing externally threaded upon opposite sides of its transverse center for turning into a pipeline and having an internal radial flange therein adjacent one end thereof, a longitudinally fluted elongated valve stem movable in said casing endwise and having a tail end slidable in said flange, and an enlarged disc-like head end adapted under movement of said stem in one direction to seat against the opposite end of said casing and close the same, said stem being radially enlarged adjacent said head end thereof for bearing against the inner wall of the casing, a helical spring sleeved onto said stem between said flange and enlarged end of the stem and urging the latter in the opposite direction, and a member detachably mounted on the tail end of the stem and coacting with said flange to limit movement of the stem in said opposite direction, said member comprising a split resilient ring having interlocking engagement with said stem.
