Abstract
1324168 Valves IMPERIAL CHEMICAL INDUSTRIES Ltd 23 Dec 1970 [31 Dec 1969] 63516/69 Heading F2V A rotatable plug valve has a valve member 72, 76 with a flow port or a peripheral flow passage 74 which co-operates with one or more body ports 71. At least that part of the plug adjacent a port 71 in the closed position of the valve, is formed from a pliable material, and is provided with a blind indentation or recess which overlies the port. Creep of the pliable material into the port, and tearing, are thereby avoided. The pliable material contains at least 60% by volume of a low-friction fluorine-containing polymer e.g. P.T.F.E.. polychlorotrifluoroethylene, polyvinyl fluoride, polyvinylidene fluoride, or copolymers of P.T.F.E. containing ethylene or hexafluoropropylene. The area enclosed by the indentation may be from 10% to 30% greater than the area of the port. As shown, the plug consists of an outer cylindrical portion 72 of P.T.F.E. and an inner plug 76 of elastomeric material which is compressible e.g. by a headed stem 77, 78 screwed into a button 79, to expand the outer portion into sealing engagement with the body. In modifications, the inner plug is compressed by a screw (50) or simply plugged into the outer portion, Figs. 4 and 6 (not shown). The valve may be of multiple-way type, Fig. 8 (not shown). In other embodiments the plug is conical and made in one piece of P.T.F.E. The plug has an integral handle 73.
