Abstract

719,201. Valve accessories. DEWRANCE & CO., Ltd. Jan. 30, 1953 [Jan. 30, 1952], No. 2717/53. Addition to 693,655. Class 135 In a welded slide valve housing of the kind described in the parent Specification, the stubtubes 7, Fig. 1, comprising the branch connections are formed with inwardly tapering bores 14 and seating surfaces 13 and the strength of the butt welds 11 surrounding the flanged openings 5 are made at least equal to the strength of the butt welds 12 between the stub-tubes and the pipe line by enlarging the external diameter of the stub-tubes adjacent the flanged openings. In a modification, a recess 19, Fig. 2, is formed in the inner end of each stub tube 7 and a separate seat member 18 welded therein.
