Abstract

1,235,623. Valves. SOC. DE ROBINETTERIE S.A.J. 3 Feb., 1969 [2 Feb., 1968], No. 5752/69. Heading F2V. In a butterfly valve having a housing 1, an inlet 4 and an outlet 2, the closure member 3 is mounted on a spindle 8 which is cranked twice, in the manner of a crank-shaft. The spindle has a central, rectangular portion 25 from one side of which projects a lug (Fig. 2, not shown), to which lug the closure member mounting rivet 7 is secured, a spacer element 26 being interposed between the lug and the closure member. With such an arrangement, the closure member 3 is pivotable within the outlet 2 between the closed position shown, and an open position (Fig. 2). In a modification (Fig. 4, not shown), the closure member is mounted on a spindle which is cranked only once and which pivots in an overhung manner on one side only of the duct 2. In a further modification (Fig. 5, not shown), the closure member is mounted directly on the spindle intermediate piece. In all the above embodiments, sealing of the closure member with respect to the duct 2, is effected by mounting a sealing ring either within the inner periphery of duct 2 or on the outer periphery of the closure member.
