Abstract
1365330 Valves DE ZURIK CORP 30 Dec 1971 [6 Jan 1971] 60776/71 Heading F2V In a valve, e.g. of the butterfly type, comprising a closure member 22, Figs. 2 and 3, attached to a shaft 24 for pivotal adjustment via a handle (58), Fig. 1 (not shown), the periphery 68 of the closure member contacts a resilient sealing ring 60 when the closure member is positioned to close the flow passage 14. The sealing ring, which is preferably of P.T.F.E., is stretched by the closed closure member, but has shoulders 66 engaged by metal hoops 65 which assist in returning the sealing ring to its unstretched state when the closure member is moved from its closed position. A radial web 64 of the sealing ring is engaged by an annular spring 70 to provide sealing between the ring and valve body 12. The sealing ring is radially movable in groove 62 to provide a self-centring effect. Fluid may flow through the passage 14 in either direction, the fluid flowing from the H.P. side into groove 62 enhancing the sealing action of the ring. The web 64 has radial grooves 79 to allow the H.P. fluid to pass to and from space 78. A removable cap 48 permits access to shaft 24 for removal and replacement. In an alternative embodiment, Figs. 6 and 7 (not shown), the sealing ring has only one shoulder and has a respective metal hoop engaged over the shoulder and over the periphery of the radial web.
