Abstract
586,761. Lubricating valves. NEWMAN, HENDER, & CO., Ltd. July 31, 1944, No. 14582. Convention date, July 2, 1943. [Class 135] Lubricant is . supplied at all times to diametrically opposite long grooves 40 on the face of a rotary plug valve which are not exposed to the line fluid, and only when the valve is fully open or fully closed, to shorter independent grooves 38 which have to move across the fluid passageway. The lubricant is supplied from an axial bore 44 in the plug through radial holes 42 to the grooves 40, which latter open into an annular groove 64 formed at the head of the plug. Communicating with the lower end of grooves 40 are radial and chordal passages 58, 56 and 54 which assist in the distribution of the lubricant over the lower seating surfaces. The grooves 38 are connected to the lubricant supply only in the fully open and fully closed positions of the valve by means of recesses 12 in the seating surface of the valve body which connect the grooves 38 with radial holes 52 from the axial bore 44. An annulargroove may connect the outer ends of the radial holes 42 and 52 at the top of the plug. The base of the plug is exposed to the line pressure through holes 36 to increase the seating pressure of the shoulder 62 of the plug against the body.
