VALVE.
Application filed December 10, 1920.
To all 10 tom it may concern:
Be it known that I, LYDDANE SMITH, a citizen of the United States, residing at Owcnsboro, in the county of Daviess and State of Kentucky, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of. the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to new and useful improvements in valves, more particularly to what is known as a vertical check valve adapted for use in pumping liquid, the main object of the present invention being the provision of a valve of this type which can be used in a comparatively small casing with respect to the amount of suction obtained.
The valves in use at the present time for pumping liquids from wells or other sources, require a considerably larger casing than the valve body and particularly a much arger casing than the suction pipe which is used in connection with the valve and it will. be noted from the following description and the accompanying drawings that we have provided a valve wherein the size of the casing can be materially reduced with respect to the size of the suction pipe used, thus saving the cost of the necessary large casing for use in pumping liquid from wells or other like sources.
Another object of the present invention is the provision of a valve having a check member therein provided with means whereby to automatically seat the valve upon the return of the suction stroke and also to do away with the guide members in use at the present time arranged above the check valve so as to provide for a free flow of the liquid into the suction pipe.
With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings in which:
Figure 1 is a vertical sectional view of my improved valve illustrating the same in position within the casing, the check member being shown in elevation;
Serial No. 429,708.
Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 3;
Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1.
Referring now more particularly to the drawings 1 indicates the well casing and arranged therein is my improved valve body 2 which in the present instance isshown as substantially elongated in form and provided with a plurality of inlet openings 3. The upper end of the valve body 2 is provided with an outlet portion 4, the upper end of this outlet portion having an annular seat as shown at 5 upon which the check valve 6 is adapted to seat upon the inward stroke of the suction.
The valve 6 includes in its construction an inverted conical shaped body 7 having a guide stem 8 projecting therefrom into the body 2 of the valve, and secured to the valve at the base of the member 7 is a washer 9 securely held in place by means of the metal cap plate 10 which is secured to the valve member in any suitable manner. From this it will be apparent that when the valve is in its closed position, the washer 9 normally bears upon the annular seat 5 of the body 2 to prevent backward movement of the liquid after having been passed out through the outlet portion 4.
The exterior of the outlet port-ion 4: is threaded and adapted to engage within the lower end of a connecting member 11, the connecting member 11 having a suitable chamber 12 formed in its central portion whereby the liquid after passing up through portion 4 can readily circulate around the valve member 6 and pass upwardly into the suction pipe 13 which is threaded into the outer end of the connecting member 11.. It will be noted that the suction pipe 13 is located directly in alinement with the outlet portion 4 so that the liquid after passing around the valve member 6 in the chamber 12 will readily pass out through the suction pipe 13. In order to limit the outward movement of the check valve 6, a transverse pin 14: is arranged within the chamber 12, the ends of which are secured in position within the side walls of the connecting member 11. From this it will be apparent that as the suction draws the liquid upwardly it will pass through the portion 4 around the is used in connection with my valve member 6 and through the chamber 12 into the suction pipe 13. Upon inward movement of the suction drop downwardly, the inverted cone shaped portion 7 guiding the valve into its proper ,position so "that the washer 9 will readily seek its proper position upon the annular valve seat 5.
In the well known type of suction valves in use at the present time for pumping liquids from Wells or like sources the 'valve member isconstructed of such a size that it requires a minsiderably "larger casing than that with which my improved valve can be "used. It Willbe noted from the accompanying drawings thatthe suction pipe 13 which improved valve is slightly less in diameter than the casing; .1 with which the valve is used, but in the valves in use at the present time a greater diameter of casing is required with respect to ithe ldiametervo'f the suction pipe, thus inthe valve 6 will creasing the cost of a necessarily large casing {or the pumping of a small amount of liquid. From this it will be apparent that my improved valve permits the use of a larger suction in avel-l casings than can be obtained using :the old and -W8ill .knovvn forms of check values.
I claim as my invention:
In combination, a tube closed at its lower end and having thickened Walls at the opposite end thereof, said tube being provided with a plurality of spaced perforations through its Wallpthe peripheral-edged said thickened 'end forming a valve seat, a valve co-o iierating "with said seat, said valve being of less diameter than the diameter of said tube, said end being 'exteriorly threaded, and a sleeve member in threaded engagement With said end.
ln testimony whereof I-affix my signature.
LYDDANE SMITH.
