Abstract

865,388. Rotary plug valves. BROOKSBANK Ltd., J. Nov. 27, 1958 [Dec. 3, 1957], No. 37696/57. Class 135. A rotary plug valve comprises a valve body 1 having aligned inlet and outlet ports 2, 3 and an opening in its top closed by a cover 7 through which a valve plug 6 may be inserted. The plug which is mounted for rotation about an axis normal to the axis of the ports on a stub bearing 22 and an operating spindle 24 formed with a spigot 28 engageable in a socket 29 in the plug to rotate the latter, is formed with a recess 32 on its peripheral surface in which is clamped by means of a clamping-ring 33 and screws 34 a resilient annular ring 31. The ring 31 which is tapered on its inner periphery for engagement with a complementary taper on the ring 33 has a semi-circular section top protruding from the plug surface for engagement with a partspherical land 16 in the valve body when the valve is closed. The amount the ring 31 protrudes may be adjusted by the clamping screws 34. Sealing-rings 21, 26 prevent leakage from the valve body around the stub bearing and the operating spindle respectively. In a modification, there may be two diametricallyopposite recesses 36, 37, Fig. 8, each of which mounts an annular resilient ring.
