J. M. SHARP VALVE FOR PUMPS Filed May 16, 1927 ATTORNEY Patented Nov. 13,
JEFFERSON M. SHARP, OF OIL CITY, PENNSYLVANTA.
VALVE FOR PUMPS.
Application filed m 16,
My improved valve for pumps is suitable for use with various types of pumps both hand and power-operated, and is designed to -meet certain requirements and to possess certain advantages not heretofore possessed by valves of this type, namely:
(1) Simplicity; facility and economy of construction and production,'especially in the I respect that both the valve and the valve-cage may be formed from bar stock and the forming operations may, in the main be performed upon an automatio screw machine.
(2) Efliciency under heavy and exacting classes of service; comparativelylonger life in all classes of service, due to its rugged con- 7 struction; the ample and accurately alined guiding surfaces for the valve in its reciprocations, and the fact that the valve proper is invertible or reversible at will with reference to its seat, whereby the valve organization is adapted to render a term of eflicient service of substantially twice the length of that rendered by .valves heretofore in use.
let
The construction whereby I am enabled to secure said objects is clearly illustrated in theaccompanying drawings in which:
Fig. 1 is a central, vertical section through a valve cage and the adjacent cooperating portion of a pump cylinder, the valve proper being shown in elevation.
Fig. 2 is an elevation of the valve-cage; the lower end in this view being shown as having a screw-threadedend instead of the smooth periphery of the Fig. 1 form.
Fig. 3 is a section on line III-III of Fig.
. is given to show a modified form of vent or The construction shown in said drawings is substantially as follows: 7
The adjacent walls of the pump cylinder, in which my improved valve is mounted are indicated by the reference numeral 1; the outer valve port is supplied with a removable cover 2, which may be secured in position in the usual manner.
The inner valve port 3 communicates with the bore of the pump cylinder. Within said valveports is mounted a valve-cage which consists of a substantially tubular structure 4, having an open top and through .the side 1927. Serial No. 191,753.
walls of which are formed the ports 5. Said cage is also provided internally, adjacent its lower end, with an integrally-formed valve seat 6. The lower end of said tubular valvecage is formed for leak-tight insertion into its co-operating inner cylinder port 3, either by means of the smooth tapered periphery 7 or by the screw-thread 7 The valve proper Fig. 5, consists of a spoolshaped body having the heads 8.8, which are of identical shape, size and construction, each of which is providedwith a chamfered seating edge or face 9.9 for interchangeable, invertible co-operation with said seat 6 within said cage.
A certain portion of the valve, intermediate said heads is cut away as at 10: the diameter of said heads is slightly less than the internal diameter of the cage, whereby said valve is adapted to have free vertical movement therein, and the periphery of each of said heads to have guiding contact with the cage walls as the valve reciprocates vertically therein; thus formed, the valve and cage are provided with large co-operating guiding surfaces which construction materially contributes to and prolongs the efliciency of the valve organization.
For the purpose of causing the valve to seat more quickly than it might otherwise do, a spring 11 may be, if desired, employed, and suitably mounted between adjacent portions of the to of said valve and the cover 2.
For tile purpose of providing against a sluggish action of the valve upon. account of the presence of fluid, or a tendency to a vacuous condition within the chamber 12, bypass passages as 13 in Fig.1, or 14 in Fig. 6, may be provided, andin case the Fig. 6 form of by-pass 14 is employed with a screwthreaded form of cage, said grooves 14 ma be employed for the insertion of a wi'enc for screwing the cage into its service position. A tapped hole 15 may be utilized for grinding the valve to its seat also for removing the valve from the cage.
From the foregoing description it will be readily noted that my improved valve organi zation consists essentially of a tubular cage, the bore of which is wholly unobstructed by a spider construction of any kind which would cause resistance or obstruction to the flow of fluid through the valve organization is reduced at one end to form an annular shoulder that is adapted as a seat for the valve and that the valve proper consists of a spool prising a substantially tubular valve-cage shaped body both heads of which are adapted to selectively seat upon said cage seat, and
that the interior face of the walls of the larger 7 portion of the cage bore and the peripheries of the valve heads are adapted to have guiding contact witheach other.
I claim the following: 1. A valve organization for pumps comprising a substantially tubular valve cage" having an open upper end, whereby the free insertion and removalof the valve is provided for forming a guide-chamber for the valve and having a valve-seat adjacent the lower 'end thereof, and a spool-shaped Valve each. head of which is provided with a seating face, which faces'are adapted to interchangeably seat upon said valve-seat; the peripheries of said heads being adapted to have guiding contact with the innerwalls of said cage. 2. A valve organization for pumps c'omhavin an open, unobstructed upper end where y free access to and'remova-l of the valve is provided for, the upper portion of which is provided with ports and forms a guide-chamber for the valve, the-lower portion of said chamber being provided with an cage;
inwardly projecting valve-seat, and a spoolshaped valve the heads of which are provided with seating faces adapted to interchangeably seat upon said valve-seat; the periph- I eries of said heads being adapted to have guiding contact with the inner walls 3. A valve organization for pumps comprising in combination with a carrying structure comprising a portion of the cylinder of a pump provided with a tapered .port for the reception of a correspondingly-formed portion of a valve-cage, a substantially. tubular valve-cage having a portion thereof formed to seat leak-tight in said ta red port, a
upper end thereof open, whereby ready re-- moval, inversion and reinsertion of the valve 1s provided for.
In test mony whereof I aflix niy signature.
