Abstract
710,052. Valves. VEREINIGTE ARMATUREN-GES., and BOPP & REUTHER-GES. Aug. 25, 1952, No. 21298/52. Class 135 A slide valve comprises a closure member slidable between seats b, Fig. 1, and made up of plates c, c<SP>1</SP> separated by wedges e, f, the operating stem d driving a nut l engaging slots in the plates. A stop k in the housing causes wedge e, when the valve is closed, to engage wedge f so that further rotation of the stem causes movement of plates c, c' against the seats. When the valve is opened, the end 'm of the stem abuts wedge e so that further rotation of the stem causes movement of the plates against the seats. The plates are constantly urged against the seats by springs h, h<SP>1</SP>, Fig. 2, acting between collars o screwed to wedge f and heads n abutting wedge e. The collars are adjustable after removing the bonnet p, without removing the closure member from the housing. The seats may comprise separate rings t, Fig. 7, screwed or welded in the housing flow ports, and plates s which may be spring urged against the closure member. The spaces in the housing may be filled with lubricant, and lubricant may be supplied to the gap between each ring t and plate s from a point outside the housing.
