Abstract

A valve device employs a flexibly deformable sleeve (12) mounted in a support body (10) and encircled by a ring (26) which is rotatable about a diametral axis so that it can be turned into a position in which it pinches the sleeve at spaced positions along the length of the sleeve and thereby cuts off flow of material through the sleeve. <IMAGE>

Description

SPECIFICATION Valve device for handling materials This invention relates to a valve device for use in handling materials, especially particulate materials such as solid residues from nuclear reactor fuel.
According to one aspect of the invention there is provided a valve device including a resiliently deformable sleeve and means external to the sleeve for pinching the sleeve to close off flow of material through the sleeve.
According to a second aspect of the present invention there is provided a valve device comprising a flexibly deformable sleeve and a pinch member for effecting pinching of the sleeve to cut-off flow of material through the sleeve, characterised in that the pinch member is rotatable and has portions which can contact the sleeve at opposite sides of the sleeve, the arrangement being such that rotation of the pinch member into its operative position is effective to pinch the sleeve, by means of said contact portions, at spaced positions along the length of the sleeve.
In one embodiment of the invention, the sleeve is of round section and the pinch member comprises a ring portion through which the sleeve passes, the ring portion being rotatable about an axis extending diametrically of the ring. In the open position of the valve, the ring portion is disposed with its axis generally parallel to the longitudinal axis of the sleeve. Closure of the valve is effected by rotating the ring portion about its axis of rotation to pinch the sleeve to such an extent that flow of material is cut off.
One example of the invention will now be described by way of example with reference to the accompanying drawings, in which: Figure lisa front elevation of the valve device; Figure2 is a longitudinal sectional view taken in the direction A-A in Figure 1; Figure 3 is a cross-sectional view taken in the direction B-B in Figure 1; and Figure 4 is a schematic view looking along the axis of rotation of the pinch member and illustrating closure of the valve.
As shown, the valve device comprises a body 10 in which there is mounted a generally cylindrical sleeve 12 of a suitable flexibly deformable material, the ends 13 of which are securely fastened in the body 10 by means of tapering inserts 14 which wedge into conically-shaped openings in end-pieces 18. The central section 20 of the sleeve 12 together with the bores 22 of the inserts 14 define a flow passage through which fluent material can pass when the valve is open.
The device also includes a pinch member 24 in the form of a circular ring 26 which encircles the sleeve 12 and is provided with diametrically-extending trunnions 28 journalled in side-pieces 30 of the valve body. One of the trunnions 28 is adapted for engagement with a suitable actuator (not shown) for effecting rotation of the ring 26 between the open position of Figure 2 and the closed position of Figure 4.
It will be observed that when the valve is closed, the sleeve 12 is caused to kink and is pinched over a substantial part of its length, ie. between the positions 32, 34 in Figure 4 thereby effecting secure closure of the valve device.
1. A valve device including a resiliently deformable sleeve and means externai to the sleeve for pinching the sleeve to close off flow of material through the sleeve.
2. Avalve device comprising a flexibly deformable sleeve and a pinch member for effecting pinching of the sleeve to cut off flow of material through the sleeve, characterised in that the pinch member is rotatable and has portions which can contact the sleeve at opposite sides, the arrangement being such that rotation of the pinch member into its operative position is effective to pinch the sleeve, by means of said contact portions, at spaced positions along the length of the sleeve.
3. A valve device as claimed in Claim 1 or 2 in which the sleeve is enclosed within a supporting body.
4. A valve device as claimed in Claim 3 in which pinching of the sleeve is effected solely through the intermediary of the pinch member, ie. without relying upon co-operation between the pinch member and the supporting body.
5. Avalve device as claimed in Claim 2,3 or 4 in which the pinch member is in the form of a ring which is rotatable about an axis extending generally diametrically of the ring and generally transversely of the longitudinal axis of the sleeve.
6. A valve device substantially as hereinbefore described with reference to, and as shown in, the accompanying drawings.
