Abstract
1321199 Valves; tubes; pipe couplings LAWJACK EQUIPMENT Ltd 12 May 1971 14482/71 Headings F2G F2P and F2V A sleeve for a pinch valve comprises an elasto - meric inner wall 7, Fig. 1, which defines a smooth flow path, circumferential fabric layers 8 extending along the length and between the ends of the sleeve outside the inner wall, and a pair of circumferential reinforcements A, B located about the inner wall and adjacent the end portions of the sleeve, the mid portion of the sleeve being adapted to be deformed to close the fluid path. As shown, the reinforcements are built up in double conical form from additional layers of fabric laid between radially inner and outer layers of the axially extending layers 8. This shape allows some freedom for the layers 8 to deform along with the inner wall 7 without excessive stretching. The layers 8 at their ends may be formed round metal rings 12 and sealed by a layer of elastomeric material to form end flanges 3, 4. A similar layer 10 extends continuously over the reinforcements A, B and over the mid portion of the sleeve. The sleeve may be pinched between anvil members 5, 6, or deformed by fluid pressure applied externally. In an alternative embodiment, Fig. 3 (not shown), a layer (11) of elastomeric material is wrapped immedially around the outer surface of wall 7 to form a base for each reinforcement A, B.
