To all whom it may concern:
Be it known that l JAMES CLAYTON, sub ject of the King of Great Britain and lreland, and resident of Blackpool, in the county of Lancaster, England, have invented certain new and useful Improvements in Valves (for which I have applied for a patent in Great Britain onMay 28, 1919,
atent No. 154,948), of which the following is a specification.
My invention relates to improvements in that class of valve having two separate cylindrical bodies within the main casing on a centre line at right angles to the operating spindle to which the valve is geared and a concentric cross-sectional area of flow between the cylindrical-bodies forming the valve and the valve casing, which bodies engage with one another, one being fixed and provided with a seating and the other provided with a facing surface and movable through the agency of an operating spindle to determine the flow of the liquid or fluid, the object being to provide improved means for operating a valve of this type; improved means of mounting the valve; means for allowing the internal parts to be examined and interchanged; means for permitting expansion of the valve, a removable valve face and means for allowing same to seat squarely and for moving the face to all a difl'erent part of the seat when required.
With the aforesaid objects in view my invention consists in the combination with the valve casing of a stufling box and gland surrounding the operating spindle and a collar on the'inner end of said spindle cooperating with the stufiing box to form a tight joint round the spindle; the combination of the innervalve casing supporting the valve proper with a removable cover adapted to allow the wholev of the valve parts to be removed from the casing of the valve; the means for allowing the screwed spindle for operating the valve to be removed from the valve casing in which it is located consisting in passing one end of the spindle through such casing and securing thereto a removable collar and a removable covering cap attached to the casing; in means for allowing expansion and contraction of the valve parts consisting in locating a spring between the end of the collar on the spindle and the coverlng cap; in a renewable valve face composed of a seat- 1920. Serial No. 3&635t.
valve face comprising a partly spherical dlsc having a curved inner face to bear upon a corresponding face on the valve body and a central screwed shank passing through the latter and secured by a nut and a washer having a convex face seating in a concave on the valve body, the whole arrangement enabling the valve to accommodate itself to the seat; and means for circumferentially adjusting the face when required, consisting in forming the valve with bevel teeth on its rear face and using in conjunction therewith to operate in the extreme open position of the valve a bevel pinion operated by a shaft passing to the outside of the main valve casing and a stufiing box for keeping the shaft liquid tight. j
My invention will be fully describedwith reference to the accompanying drawings in which- Fig. l, is a longitudinal section of a valve constructed in accordance with my invention,
Fig. 2, transverse section of valve body,
Figs. 3 and 4: similar views showing modification of the valve,
Fig. 5, similar view to Fig. 1, of a valve with further modifications,
Fig. 6, transverse section of a valve showing modified 'means for operating it,
. Fig. 7, section of a valve showing a further form of renewable valve face and gear for operating the valve and Fig, 8,; partial section of valve showing a modified form of the renewable face and means for rotatingit.
Similar reference characters are applied to corresponding parts in all the views of the aforesaid drawings.
Referring to Figs. 1 and 3 a indicates a stationary casing, flan ed at each end for of the inner casing c. The valve is supported by the long bearing formed by the coacting parts.
In accordance with my invention and referring to Figs. 1 and 3, the valve 7) is slidable within the casing c by providing its boss m with a screw thread, a corresponding thread being formed upon the spindle 71..
The spindle carries a bevel wheel n in gearwith a bevel pinion 0 carried by a spindle 1) having a collar q working in a recess 7 in the main casing a. Above or in continuation of the recess is a stuffing box 8 fitted with a gland t and bottom ring u. These parts keep the spindle p liquid or fluid tight whilst allowing it to be freely operated to move the valve Z) to or from its seat 0 The latter is formed in this instance by a re movable ring 41. The valve is prevented from rotating by a narrow guide piece an engaging with a groove a: in casing 0. The valve is fitted with a renewable seating ring 1 to engage with the seat 0 The screw valve spindle 'is adapted to be removed from the casing 0 by carrying its end 2 through the casing and fitting it with a removable collar nut 3. This nut keeps the spindle in position axially whilst permitting it to rotate. The collar is enclosed by a removable cap 4; fixed to the casing c by screws 5.
' In Figs. 3 and 4 the casing c and all the main valve parts are carried by a remow able cover 6 which forms the upper portion of the main valve casing a. to which it is secured removably by studs and nuts 7. The valve 6 is arranged and operated in a substantially similar manner to that in Figs. 1 and 2 except that in place of a stufling box the operating spindle ;0 has a collar 8 which makes a working joint with a subsidiary cover 9 secured to cover 6 by studs and nuts 10. By removing the cover 9 the operating spindle can be removed when required whilst on the other hand by removing the cover 6 the whole of the valve parts can be entirely taken away from the casing (1. and be replaced by others if necessary, or be examined and repaired.
11 is a hand hole through which parts of the valve may be examined whilst in position, this hole being adapted to be suitably closed by any approved cover, which is not shown. y
In Fig. 5 the valve is also provided with a removable cover 6 as in Figs. 3 and 4 but is provided with a stuffing box and packing arrangement similar to that shown in Figs.-
1 and 2. The chief modification however in this design consists in the employment of a spring 12 located between the outer end of the collar nut 3 and a removable cap 4 which differs from the cap shown in Figs. 1 and 3 in that it is recessed to receive the outer end of the spring 12. The portion 2 of the spindle la. is somewhat longer than the partition 13 between the collar nut 23 and the bevel wheel n so as to allow the expansion of the valve taking place under heat and to follow up contraction of the valve when it cools. This arrangement enables the valve to be easily operatedc In Fig. (3 I have shown improved means for moving the valve 7) backwards and forwards, this consisting in fixing av worm wheel 12 on the spindle 7:. with which gears a worm 13 carried by a shaft 1% mounted in bearings 15 in the removable cover (i. The shaft 14 is operated by a hand wheel 17. 16 is a removable cover secured to the cover 6 and located above the worm 13.
In Fig. 7 the renewable face ;1 is in the form of a ring mounted upon the shank y and held in position by a plate y and nut 3 In the same figure the bevel pinion n is formed in one with the short shaft 2 which passes into a recess 18 formed in the casing 0 instead of passing entirely through as in the examples previously described. In Fig. 7 also I have shown holes 19 through which lubricant can be passed to the chamber containing the bevel wheels and screw 71, thereby enabling the whole of the moving parts to be lubricated.
Fig. 8 shows a still further form of renewable valve face which in this case consists of a partly-spherical disc 20 curved on its inner face at 21 to correspond to a similar face on the valve body I). The disc is secured to the latter by a short freely fitting screwed stud 22 nut 23 and a washer 24 flat on one side and partly spherical on the other to fit a corresponding hollow face in the valve body. Thus when the valve is being forced to its seat it can freely accommodate itself to the latter and make a tight joint. Means are also shown in Fig. 8 for turning the valve disc 20 with the stud 22, when required, to allow it to seat at a different position. To this end the disc is provided with bevel teeth 25 which engages with a bevel pinion 26 when the valve is open. The pinion is fixed on a shaft 27 passing through the removable valve casing 6, fitted at its outer end with a handwheel 28. A stufiing box and gland 29 is used to keep a tight joint about the spindle. By rotating the shaft 27 the valve can be moved circumferentially to the position required. The bevel teeth are out of engagement when the valve is closed. i
In some cases the gland 9 may be flanged and be adjusted by the ordinary screws and nuts. Again the main casing a may be fitted with a small removable cover at the bottom to enable the valve and gland to be got at for examination or And, when required a drain cock may be fitted at this point also to drain out the liquid or sediment from the valve casing.
adjustment.
amet What I claim and desire to secure by Letters Patent is:
1. In a valve, a main casing provided with a passage and a valve seat, an internal casing arranged in the said passage against one side of themain casing and provided With a cylindrical bore in line with the valve seat, a valve for cooperating with the valve seat to close the passage, said valve having a screw threaded hole and a stem which is slidable in the said bore, a screw threaded spindle journaled in one end wall of the internal casing and engaging with the screw threaded hole in the valve, and means for revolving the said spindle to open and close the valve 2. A valve as set forth in claim 1, and in which the means for revolving the valve spindle comprise a beveled toothed Wheel secured on the said spindle, an operating spindle journaled in one side of the main casing, and a beveled toothed wheel secured on the said operating spindle and gearing into the aforesaid beveled toothed Wheel 3. In a valve, a valve casing, a valve, a removable screw threaded spindle for operating the valve, said spindle having an end portion which is journaled in the said cas ing, a removable collar secured on the said end portion of the spindle and normally retaining it in position, and a removable covering cap for the collar attached to the said casing.
4c.- The combination, with a valve as set forth in claim 3, of a spring arranged between the said collar and cap and operating to press the collar against the casing.
5. In a valve of the type described, a valve body, a renewable valve face comprising a partly spherical disc having a curved inner face to bear upon a corresponding face on they valve body and a central screwed shank passing through the latter and secured by a nut, and a washer having aconvex face seating in a concave face on the valve body, the whole arrangement enabling the valve to accommodate itself to the seat.
6. In a valve of the type described, the combination, with a removable valve face as claimed in claim 5, of means for circumferentially adjusting the disc in the extreme open position of the valve consisting of bevel teeth on the rear face of the disc, a bevel pinion engaging with said bevel teeth, a shaft for operating the pinion passing to the outside of the main valve casing, and a stufiing box for keeping the shaft liquid tight.
In testimony whereof l[ have hereunto set my hand in the presence of two witnesses.
