Abstract

390,711. Gate valves. LAURENT, M. P., 604, Merrill Street, Houston, Texas, U.S.A. Aug. 25, 1932, No. 23810. [Class 135.] A gate valve has renewable seats 26 with cylindrical projections 30 engaging recesses 31 in the housing A to render them self-aligning, and side ribs 28 for guiding the valve member 41, 42. Leakage between the valve faces is prevented by circular or rectangular packing rings 36 urged towards the valve member by spring rings 37. The valve member is formed in two parts 41, 42, and a leaf spring 50 on each side thereof holds the two parts together. The adjacent faces 40 of the parts 41, 42 are inclined to one another so that when the valve is fully open or fully shut the portion 42 abuts either a projection 17, or 18, to effect a jamming action. The contacting faces of the two parts 41, 42 may have spring-pressed sealing rings similar to the rings 36.
