Abstract
717,729. Valves; regulating fluid flow. HENSLEY, C. A E. Nov. 10, 1952 [June 19, 1952], No. 28207/52. Class 135 A fluid control valve constructed to permit the gradual increase or decrease of fluid flow through the valve to reduce erosion strains and vibrations in the valve parts comprises a plunger 35, Figs. 1, 2, having helical grooves 37 in spaced relation to similar grooves 12 in a casing 2 to form a gap 38 of abruptly changing cross section. The casing 2 is formed with three grooves 23, mounting keys 22 having threads 24 engageable with the grooves 37 in the plunger 35 to enable the plunger to be axially moved on rotation of an hexagonal shaft 46 which co-operates with an hexagonal hole 44 in a plate 39 secured to the plunger. When fully closed the plunger 35 engages a resilient seating 11 adjacent the valve inlet 4 and the plate 39 engages a conical seat 17. When fully open, a conical face 43 on the plate 39 abuts a seat 30 and permits renewal of packing 49 without impairing the fluid-tightness of the valve. The plunger may be moved to any intermediate position to restrict the rate of flow of the fluid to the desired amount, the energy stored in the fluid being gradually dissipated as the fluid passes axially through the varying cross-sectional gap 38, spiral flow through the gap 38 being prevented by the keys 22.
