Abstract

1,268,934. Valves. GAZ DE FRANCE. 14 March, 1969 [15 March, 1968], No. 13615/69. Heading F2V. A silent reducing valve has a porous seat 12 through which the gas must flow under the control of diaphragm 13 which is subjected to the pressure in a loading chamber 15 and cooperates with surface 12b of the seat and end 11a of inlet nozzle 8. The surface 12a of the seat is sealed to flange 11 of nozzle 8 and gas leaves the seat via surface 12c. An expansion chamber 17 surrounds the seat. The sectional profiles of surfaces 12a, 12b approximate to logarithmic spirals generated by the ends of imaginary curved lines the last of which defines the shape of surface 12c. These lines are related by an exponential relation and increase in length at an increasing rate in the flow direction. The seat cross-section is such that the flow velocity remains constant, and frictional heating precludes excessive cooling due to the pressure drop. In a modification the seat can consist of a ring of tapering porous elements of circular cross-section the spaces between the elements being filled-in. In either case, smaller particles can be used at the upstream end of the seat then at the donwstream end.
