Abstract

536,993. Valves. MILLER, T. W. Feb. 26, 1940, No. 3577. [Class 135] A simple valve adapted to be machined easily and to be of service when grit or corrosive substances are encountered is formed of a tubular wall 16 of rubber or rubber fabric and a disc 11 mounted on pivots 13, 22 which are passed through apertures in the wall 16 and are mounted in bearing parts 21, 26 of a hinged casing 17 the parts of which are held together by dowels 39 and bands 35 fitting on tapered parts of the casings. The disc 11 acts as a butterfly valve, and is of streamline shape in its open position. Collars 14, 23 with rounded edges 38 are secured to the disc 11, and afford a tight joint around the pivots 13, 22 by pressing the tube 16 against the casing. The tube 16 is secured at each end to the casing 17 by a short tube 27 which is grooved and clamps the tube to the casing. The tubes 27 are integral with screw unions 30 for connecting to inlet and outlet pipes,.and the hexagonal extensions 31 of the unions are engaged by overlapping ends 32 of the casings to prevent the tubes 27 from twisting. In a modification the collars 14, 23 and the wings of the disc 11 may be made in two parts separated by a resilient disc which makes a tight joint with the tube 16 when the valve is closed.
