Abstract

418,451. Valves; jointing. HOPKINSONS, Ltd., BROWN, R. L., and SEWELL, G., Britannia Works, Huddersfield. April 25, 1933, Nos. 12004 and 19615. [Class 135.] In securing a facing a in the seat b of a steam &c. valve, where the seat is of such smaller size that the facing can be inserted when at a lower temperature (as when cooled by liquid air &c.) being firmly held when the temperatures equalize, one of the meeting surfaces, c or b<1>, of the seat or facing is provided with serrations which bite into the corresponding meeting surface of the facing or seat. The facing and the seat may be tapered and the degrees of taper may differ in such a way as to set up the greatest stress at the innermost surface. The peripheral faces may be partly cylindrical and partly sharply tapered to cause an inward wedging action.
