[Also in Division F2] A yoke for a slide valve includes a cover 2 integral with the outer part 3 of a stuffing-box, a head 1 for receiving the spindle nut, channelsection legs 4 arranged diametrically to each other and spacing the head from the cover and lugs 8 integrally forged with the legs to receive the mounting pins of clamping bolts 9 for the stuffing-box cover 10. The two channelsection legs are of trough shape in cross-section and have semi-circular ends welded to the head and the cover; plane surfaces for type plates or apertures provided with a reinforcing bead 11 may be provided. Outlets above the lower weld permit condensate to escape. All of the parts may be produced by die-forging. |
