Abstract

993,971. Valves. A. KNAPP. July 13, 1961 [July 15, 1960], No. 25338/61. Heading F2V. The diaphragm closure 6 of a valve which co-operates with a tubular seat 5 has its periphery gripped between a threaded cap 12 and the valve body 9, one or both of the gripping surfaces being other than normal to the valve axis, e.g. toric, conical or spherical so that the diaphragm assumes a cap-like shape, with its concave surface facing the seat. The valve is actuated by a threaded shaft 13 to which a hand wheel 14 is attached. The diaphragm may be reinforced by a disc 16, Fig. 6, with an integral or attached lug 17. The lug may be of considerable length so that the diaphragm may be remote from the seat. The diaphragm is made of rubber, rubberized cloth, leather or synthetic resin and reinforced internally or externally with one or more sheets of cloth or wire gauze. Sealing material and cloth as wire gauze reinforcing material may be inserted between the body gripping surfaces, one or both of which surfaces may be grooved or ribbed; one gripping surface may be rounded and of a smaller diameter than the other surface; the diaphragm and body may be of circular or oval shape and the body may be of a synthetic resin material.
