UNITED STATES GEORGE E. PUTNAM, OF FULLERTON, CALIFORNIA.
MUD-PUMP VALVE.
.Application filed February 4, 1824. Serial No. 690,496.
This invention relates to valves and valve seats, and particularly to valves and their seats employed in duplex slush pumps.
An object of my invention is the provision of an improved valve and an improved seat therefor.
Another object of my invention is the provision of a valve seat which will diminish the replacement costs of valve seats in duplex slush pumps.
A further object of my invention is the provision of a valve seat having a longer life than those heretofore employed.
A still further object. of my invention is the provision of a valve seat and a valve which will co-act to eliminate the deleterious action of sand, gravel and similar material, which have heretofore caused a comparatively rapid wearing away of previous valve seats.
Another object of my invention is the provision of a replaceable valve seat.
Another object of my invention is the provision of a rubber seat for a valve.
- Another object of my invention is the provision of a valve comprising less material than those heretofore employed.
Another object of my invention is the provision-of an orifice providing for less friction between it and the discharged material thanithe orifices employed in previous slush um s.
With the foregoing objects in view, to-
I gether with such other objects and advantages as may subsequently appear, my invention resides in the construction and arrangement of parts hereinafter described and claimed and illustrated in the accom- I panying drawings, in which Figure 1 is a view partly in'section show- 'ing'a pump valve and a valve seat, together with adjacent structures.
Fig. 2l is a cross section taken on a line 2-2 in'Figure 1, and
Fig. 3 is a detailed view showing the relation between my improved valve and a valve seat embodym my invention.
Referring to the rawings for a more detailed description thereof, the numeral 5 indicates a valve cap yoke secured to the cap 6 which has a recess 7 extendinginto its interior and thru a downwardly extending lu 8.
sleeve 9 is fitted into the recess 7 and is held therein by means of a set screw 10 passing thru an aperture in the luar 8. A valve stem 12 fits into the sleeve 9A and works reciprocally therein.
The numeral 14 indicates the valve and between the upper surface of the valve and the lower end of the lug 8 is positioned a compression spring 15 coiled around a portion of the sleeve 9 and a portion of the valve stem 12.
A frame member 17 secured to a cap 6, has a bottom portion l'a provided with an aperture, into which is fitted a castingr 19 provided in its lower portion with a frustoconical aperture 21 and having in its upper portion an aperture 22 connecting with the aperture 21 and adapted to receive the lower portion of the valve 14. The upper part of the casting 19 is recessed inwardly from the periphery of the aperture 22, and into this recess is fitted a ring 24, which is preferably a rubber ring` which. when worn out` may bereadily replaced by a similar ring. It will be noted that the rubber ring or seat 24: extends from the casting sufficiently to allow considerable wear of the ring or seat without having the valve 14 come into contact with the casting 19.
However, the casting which holds the seat encloses it over so much of its area that the seat will not suffer a permanent distortion due to the action of the valve` and thus have its useful life shortened, which happens to the seats now in use.
The rubber which I prefer to employ to constitute the seat is a'comparativelv soft rubber of a high grade which has such resiliency that foreign particles pressed into it will be rejected or expelled when the pressure is-released; thereby avoiding deterioration of the seat.
As clearly shown in Fig. 3, the upper inner portion of the rubber ring 24 is bevelled,
According to my invention the lower side portions of the valve 14 are curved to present an outwardly convex surface, and the curvature is such that when the valve 14 encounters the rubber ring or seat 24 it will first contact with the upper edge 25 of the bevel of the ring, as shown in Fig. 3.
After the first contact of the valve 14 with the edge 25 of the bevel. the weight ofthe valve brings, progressively, a larger area of U0 the bevel of the seat 24 into contact with the convex face of the valve until full seating is effected. It has been found in practice that such downwardly progressing iiicrease of contact area between the bevel and the convex surface clears the seat of most of the sand, gravel and the like which lodged on seats formerly employed and which effected a grinding action on the seat, resulting in a rapid wearing out of the same, with consequent high replacement costs.
According to ny invention, however, the
' convex surface, during its increasing contact with the valve seat, presses before it the material which may be on the seat and cause such material to fall thru the aperture in the casting 19. Furthermore, the Lbevelled seat itself, by being inclined towards the apertures in the casting 19, effects the removal o f much of the material which is deposited on it. It will thus be seen that the employment of a bevelled seat in lieu of the horizontal seat of the prior art provides a valuable improvement in pumping machines.
Thile the rubber seat of my invention will wear out, it may be readily replaced and at a low cost, since such asmall quantity of material is involved; this is a further feature of the present invention, since a valve seat of the prior art comprised a comparatively large and expensive casting whichwas necessarily entirely discarded when the surface contacting with the valve was worn out.
Slush pumps now employed in connection with hydraulic rotary drilling of oil, water diminishing the amount of friction between the discharged material and the periphary of the orice.
While I have herein described one form of my invention, modifications'thereof may be devised without departing from the spirit thereof, and it is be understood that such modifications come within the scope of this invention.
I claim as my invention:
1. A valve forv mud pumps and the like comprising an annular member having an internal annular shoulder' provided thereon, a resilient valve seat mounted upon the shoulder `having its interior surface substantially even with the interior surface of the shoul- .der, means for maintaining said valve vseat upon the shoulder, said valve vseat having its upper inner corner beveled. off upon a straight bevel to provide a seating surface, and a circular valve having a valve stem and having convex seating surfaces which .are convex both peripherally and axially of the valve adapted to seat upon the beveled Seatf .ing surfaces of the valve seat, the seating surfaces on the valve and valve seat being so arranged that the surface on the seating surface' of the valve seat contacting with the valve when the valve is seated vis located edge of the beveled seating surface.
2. A valve for mud pumps and the like Y' comprising an annular member having an aperture therethrough, there being-a groove formed upon the interior surface -of the member providing an interior' annular shoulder and a retaining flange extending partially over the shoulder, a resilient valve seat mounted upon the shoulder having its interior surface substantially even withr the interior surface of the shoulder, means for maintaining said valve seat upon the shoulder, said valve seat having its upper inner corner beveled off upon a straight bevel to provide a seating-surface, and a circular valve having a valve stem and having convex seating surfaces which are convex both, periphcrally and axially of the valve adapted to seat upon the beveled seating surfaces of the valve seat, the seating surfaces on the valve and valve seat being so arranged that the surface on the seating surface of the valve seat contacting with the valve when the valve is seated is located wholly a material distance above the lower edge ofthe beveled seating surface.
Ih testimony whereof I have signed my namerto this specification. j
