Abstract
731,267. Valves. WEIR VALVES, Ltd., HILLIER, H., and WHITE, D. May 4, 1953 [May 2, 1952], No. 11077/52. Class 135. A sluice valve comprises a main hollow body 1 of circular section with a domed end 4 carrying a stuffing box for an actuating spindle 5 and an open end closed by an internal piston-type abrasive member 9, and lateral openings in the uniform walls of the member 1 through which are welded coaxial tubes presenting seats 7, 8 at their inner ends for a sliding valve 6. The seats are faced with hard material, e.g. austenitic stainless steel. The body 1 supports a bridge carrying a wheel 27 and nut 28 whereby the screwed spindle 5 operates the valve discs 17, 18. The discs are sprung apart at 19 and telescope into each other and the saddle 20 on the spindle. The open end has sealing closure caps 9, 10, drawn together by the screw 11 and compressing a soft ring 15 and a hard ring 14 against the body 1 and a sheer ring 12 carried thereby. The ring 15 may be soft iron or soft metal known under the Registered Trade Mark " Monel " and the ring 14 of stainless steel. To facilitate the opening of the valve, by equalizing the pressures on either side of the valve 6, a small valve constructed in a similar manner to the sluice valve is incorporated in a by-pass 31, 32, the central members of both valves being in communication with each other.
