No. 1355,817 Claims priority, application France May 17, 196i) 3 Claims. (Cl. 251-175) The valves and stoppers with which are fitted the lines used in the chemical industries often must, because of their conditions of use, present some qualities: perfect tightness, working smoothness, mounting ease and, principally, resistance to corrosive products at high temperatures. Further, it is advantageous that these valves and stoppers may be operated by remote control.
A primary object of the present invention is a stopper perfectly agreeing with these different imperatives and es sentially characterized in that its closing device, serving as a valve, is constituted by a bladder, in distortable material, which may be inflated by means of a fluid in such a manner that it tightly blocks, by applying itself on a seat provided for this purpose, the line on which it is placed.
According to another feature of the invention, the closing and the opening of the stopper are obtained respectively by inflation and deflation of the bladder, without being necessary to move it.
Another object of the invention is a device permitting to displace and to bring the bladder back, and essentially characterized in that said bladder is mounted at the end of a stemcrossing tightly through the wall of the line on which the stopper is placed-and which might be given an axial translation movement by operating a nut fixed in longitudinal position, cooperating with a threading on said stem. According to another characteristic of the invention, all the parts in contact with the carried corrosive fluids, and particularly the bladder and the stem, are completely sheathed with a synthetic material, impervious to the surrounding fluids.
Other objects and advantages will become apparent in the course of the following detailed description of the different aspects of the convention, with reference to the accompanying drawings, in which:
FIGURE 1 is a transverse sectional view of an inflatable valve stopper according to the invention, provided with a device to control the valve movement.
FIGURE 2 is a transverse sectional view of a second embodiment of the mounting of the bladder on the end of the stern.
FIGURE 3 is a fragmentary cross-sectional view according to FIGURE 1, showing the shape taken by the bladder in inflated position when, according to the invention, the deformation of the bladder is used to obtain the closing of the stopper.
FIGURE 4 is another fragmentary cross-sectional View showing the shape taken by the bladder in deflated position, the deformation of the bladder being used to obtain the closing of the stopper.
FIGURE 5 shows, in a sectional view, an embodiment of the connection of the bladder bearing tube to a line of fluid under pressure.
Referring to FIGURE 1, a body 1preferably in borosilicate glass able to resist against chemicalsis made of a three tubulure cap. On the conical end e of one of these tubulures, a corresponding conical end e is fastened, having, on its inner face, a valve seat 2 and continued by an out-tubulure 3.
The end 2 is fixed on end 6 by means of adjustable metal flange 4, connected by bolts 5. Inserts 6, in asbestos-rubber material or similar, are interposed between conical glass ends 2 and e and metal flange 4. An annular gasket 7, in polyeterafluoroethy-lene or some other 3,i59,377 Patented Dec. 1, 1964 chemical corrosion resisting material, is placed between end-lips e and e and engaged by bolts 5.
The valve seat 2 may receive a valve which, according to the invention, is constituted by a canvassed special-rubber bladder or closure member 8, with a substantially semispherical shape and with a neck 9 and an anchoring twist lb.
The wall thickness of the bladder 8 decreases from its neck 9 to the base of the serni-spherical cap in order that this last part be more easily distorted than the part near to said neck.
In order to obtain a suitable progressiveness of the wall and a perfect regularity of the cap, neck and twist, the bladder 8 is preferably obtained by molding.
The neck 9is engaged onto the stamped end of a metal stem 11 and fixed on it by means of a cylindrical nut 12, screwing itself on a threaded part 13 of said stem 11, and pressing the twist 1i) against the base 11a of said stem.
The stem 11 is engaged, by its other end, in a tubulure 14 and issues forth out of the glass cap, after crossing a guiding and working device, fixed on the conical end of tubulure 14 by means of a flange 15, with insert 16 and bolts 17 by which the guiding and working device of stem 11 is fastened. I p
This last device includes a flange 18, slipped on bolts 17 and having a central sleeve 19 in which a boring 20 is made, receiving, with sliding, a cylindrical wider part 21 of stem 11.
A cotter 22, cooperatng with a cottering groove 23, prevents any rotating movement of cylinder 21 and stem 11. A nut 24, centered on the sleeve 1%, is maintained against it by a washer 25 which is fixed to flange 18 by the heads of bolts 17. This nut 24 cooperates with a threading 26 on stem 11. A control-Wheel 27 centered on the base of nut 24 is fixed on it by means of screws 28.
The stem 11, ended by an inflating valve 29, has a central channel 3% running from said valve to the stamped end on which the bladder 8 is fixed.
According to another characteristic of the invention, the different parts which are placed inside the tubulure cap and, consequently, could come in contact with corrosive material or vapours, are entirely sheathed by a chemical resistant material, preferably polytetrafiuoroethylene.
A polytetrafluoroethylene jacket 31 covers completely the bladder 8 and the cylindrical nut 12, following exactly their shape, is continued by a sheath 32, slipped over stem 11 on the greatest part of its length; the sheath is itself continued by a bellows 33, also in polytetrafluoroethylene, the base of which is inserted between the end edge of tubulure 14 and flange 18. A tightness component 35, in a material more flexible than the polytetrafluoroethylene, for instance in canvassed rubber, is fitted into base or gland 34 and is engaged in bolts 17.
The Working of the above-described device is very.
simple. The bladder 8 is inflated, through valve 29 and central channel 3t), to a pressure high enough to balance the pressure of the fluid running in direction F in the line. The bladder 8 applies itself then on its sheath 31 maintaining it stretched.
When control-wheel 27 is turned, and consequently nut 24, fixed in longitudinal position by Washer 25, the nut cooperates with threading 26 so that stem 11, to which any rotating movement is forbidden by cotter 22, moves itself axially.
Bellows 33 gives stem 11 a freedom of axial movement important enough so that bladder 8 might take the extreme positions corresponding with the opening or closing of the stopper. Therefore, this device makes possible to apply bladder 8 onto its seat 2 or, on the contrary, to move it back in order to leave the fluid running freely in the line.
The fluid, running in direction F, contributes to mains tain bladder 8 tightly applied ontoits seat when the adjusting in closing position has been correctly made.
On FIGURE 2, another different and. particularly simple embodiment of the mounting of the bladder 8 on stem 11 is shown. The stem 11 has, in this embodiment, a longitudinal boring into which a sliding adjusting hollow needle 7 36 is introduced on the conical end 3'? of which the neck of bladder 8 is engaged, the twist 16 taking position in a corresponding cavity a, disposed in stem 11. The locking of needle 36 is secured, at the opposite end, by valve 29. This embodiment is preferably applicable to large diameter valve stoppers. a 1
Theldevice according to the above-described invention is particularly well adapted for stoppersthe flow of which is relatively important, because the possibilityof remov ing the bladder allows to clear fully the seat with which it cooperates.
It is however possible, by deflating bladder 8, for instance by bringing it to atmospheric pressure, to cause a sufficient distort on of it in order to reserve an annular opening 38 large enough, in case of relatively low flow,
without it being necessary to move the bladder (FIG- URES 3 and 4). e V 7 Such a possibility of stopper control-by inflating and deflating of bladder s -rnay be exploited, according to the invention, either separately or in cooperation with the valve seat within said casing coaxial about said axis, inlet and outlet connections fixed with said casing on opposite sides of said seat, a tubular stem extending in and along said. axis within the inlet side of said casing and having its inner end adjacent said seat, said stern passing through an aperture in said casing to the exterior thereof, a hollow, expansible, ball-like closure member of resilient material secured over said inner end of said stem in pressuretight communication with the axial passage therein, a gland member of chemically-inert material secured to said casing in pressure-tight sealing relation with said aperture and having a central bore through which said stern slidably fits, said gland including an integral imabove-described control device for bladder setting. In
both cases, a line 39, connected with a compressed air main, is joined to theend of hollow stem 11 through an union-nut joint as (FIGURE 5). On the line 39, either a three-way cock or a distributor having an atmospherical vent (not shown on FIGURE 4) are inserted.
It is obvious that any fluid other than air may be used l to cause the bladder 8 to inflate or deflate and, therefore,
- vention is particularly adapted to be fitted with any suitable remote control system.
Iclaim: 1. In a valve, a casing having a longitudinal axis, a
perforate sheath extending along and fitting about said stem and closure member in fluid-tight enclosure thereof, and means mounted on said casing, exteriorly thereof, and engaging said stem to translate said stern and closure member along said axis, from a first innermost position wherein inflation through said stem of said closure member expands the latter intosealing contact with said seat, to a second outermost position wherein said closure member is free and clear of said seat, to leave substantially unobstructed the flow of fluid through said. casing.
2. The valve of claim 1, said sheath including a series of expansible and contractile bellows rings coaxial of and about said stern and contiguous to said aperture.
3. The valve of claim 2, said casing comprising a tubular constriction coaxial or said axis and terminating in an end forming said aperture, said bellowsrings expanding Withinsaid constriction by and in response to translation of said stem to-said second position, and means between saidcasing and stem restricting the latter to translation only'in and along said axis.
