This invention relates to a valve.
An object of the invention is to provide a valve of the character described having a controlling assembly whereby the Valve may be opened and closed and which has a substantially continuous conduit therethrough when the valve is in open position without internal pockets or recesses for the collection of detritus.
Another object of the invention is to provide a valve mechanism comprising a casing having an inside seat and having a core in the casing with a sleeve fitted into the casing around the core and having a threaded connection whereby upon turning movement of the sleeve said sleeve will move endwise, the casing and core having a flow way therethrough and the sleeve being provided with openings movable into and out o1" registration with the flow way upon turning movement of the sleeve, said parts being eiiective upon turning movement oi the sleeve in one direction to cause the sleeve to seat tightly against the casing and upon turning movement in the other direction to cause the sleeve to relax from its tightly seated position against the casing with means for turning the sleeve.
Another object of the invention is to provide a valve mechanism including a casing having a conduit and having a fixed core in the casing provided v/ith a conduit which is aligned with the conduit through the casing with an expansible sleeve about the core having openings and movable into one position to align the openings with said conduits and into another position to move the sleeve openings out of such alignment tociosc said conduits, said core and sleeve having co-acting parts effective to expand the sleeve to form a fluid-tight joint with the casing when the sleeve reaches the limit of its movement into either oi said positions.
A further object of the invention is to provide a valve of the character described having novel means for operating the sleeve into open or closed position.
It is another object of the invention to provide a valve having a casing and a controlling assembly therein mounted to protect the casing against the abrading influence of gritty fluid being conducted under pressure through the valve.
With the above and other objects in View the invention hasparticular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawing wherein:
Figure 1 shows a sectional View of the valve.
Figure 2 shows a side elevation.
Figure 3 shows a cross-sectional View oi the operating stem.
Figure 4 shows an end view' or" the valve sleeve.
Figure 5 shows a longitudinal, sectional view thereof, and
Figure 6 shows a cross-sectional view of the valve taken on the line 6 6 of Figure 2.
Referring now more particularly to the drawing wherein lil-:e numerals of reference designate similar parts in each of the gures, the numeral I designates a vaive casing having the conduits E ltfnerethrougli which is in alignment with the fluid-conducting pipes 3, 3 which are connected into the valve casing.
In a preferred embodiment of the invention there is aiixed core l in the casing having a conduit therethrough which is in alignment with the conduits 2. One end of the core is extended through the casing and formed into a protecting housing E. This housing may be welded or otherwise permanently secured'to the valve casing I so as to hold the core 4 stationary, The core t is externally threaded and is spaced `from the casing all the way around and threaded onto the core, and fitted closely in the casing there is the sleeve 'l which may be split from end to end at one side, as at 8, if desired, to permit its expansion and contraction, and on the other side is provided with the external, longitudinal groove 9. The sleeve has the` oppositely disposed openings i0, IG substantially equal in diameter to the vdiameter of the conduits 2, 5. Said sleeve is turnable to one position to align the openings Iii with said conduits to permit the ow oi fluid through the valve and is turnable into another position to carry'thefopenings I@ out oi alignment with said'ccnduits to prevent lsuch flow.
There are the anti-friction rings I i between the valve casing, and one end of the sleeve andthe other end of the sleeve is formed with notches I2. There isan operating stern I3 whose inner end is provided with an external, annular flange I4 having the radial lugs I5 which work in the notches I2.
There is a bonnet I i5 tted over and enclosing the stern I 3, and between the inner end oi the bonnet and the flange id' are the anti-friction bearing rings Il. The inner end of the bonnet I 6 is reduced and externally threaded and has an annular gland I8 screwed thereon whose inner face is tapered and ts into a correspondingly tapered seat I9 of the valve casing. The gland IB is of a greater outside diameter than that of the bonnet I 6 and a flange nut 20 is fitted around the bonnet and screwed onto the valve casing and has an internal, annular flange 2| Which engages the gland I8 to maintain the bonnet assembled with the valve casing. The outer end of the stem I3 has the external screw threads 22, and mounted in the outer end of the bonnet there is an operating stem 23 Whose outer end carries the handwheel 24 and whose inner end is formed with a screw-gear in mesh with the gear 22@ The stem 23 has suitable bearings in the bonnet on opposite sides of the gear 25 and is also packed with a suitable stufiing box 26. By turning'the stem 23, the stem I3 will also be turned, imparting rotation also to the sleeve 1. As said sleeve is turned, it will also be moved longitudinally relative to the core 4 on account of its threaded connection therewith. When the sleeve is turned a quarter turn in one direction, it will carry the openings IB into alignment with the conduit 2 and is arranged to be stopped in said position by its thrust against the friction rings II. A further attempt to turn the sleeve 'I will cause the intermeshing threads of the sleeve to ride up on the co-rresponding threads of the core 4, as illustrated in Figure l, causing a uniform expansion of the sleeve and causing it to fit tightly in the valve casing to prevent leakage. When the stem 23 is turned in the other direction, the stem I3 and sleeve I will be correspondingly turned in said last-mentioned direction carrying the openings IB out of registration with the conduit 2 and the co-action of the threads will move the sleeve 'l longitudinally against the flange I4, and a further attempt to turn said stem will cause the threads of the sleeve to ride up on the threads of the core 4 in the reverse position to that indicated in Figure 1 causing a uniform expansion of the sleeve, and thus causing the sleeve to fit tightly in the valve casing to prevent leakage.
It will be noted that the sleeve 1 will pro-tect the parts of the valve casing adjacent the conduit 2 and prevent said casing from being cut out by gritty fluid flowing therethrough under high v pressure. The sleeve, in intermediate position will contract and may, therefore, be easily turned.
A grease gun connection 21 may be located in the housing 6 and screwed into the valve casing I. Leading from this connection through the core 4 therey is a channel 28 which terminates in an annular channel 29 around the core'. A lubricant may be forced through the channels 28 and 29 and will nd its Way between the intermeshing threads above referred to and will also pass along the groove 9 and the slot 8 located at the open side of the sleeve 1, and will finally find its Way to all the internal Working parts so as to keep the same thoroughly lubricated. A heavy grease or oil may be used so as to also prevent leakage of the fluid being conducted through the valve.
The drawing and description disclose What is now considered to be a preferred form of the invention by way of illustration only, While the broad principle of the invention will be defined by the appended claims.
