Abstract
Abstract A control valve is provided having a control structure therein in which dissipation of liquid pressure energy is achieved by the use of two matched and opposed submerged jets that have substantially equal mass flow which result is achieved by utilizing a wall that defines an interior chamber with the matched jets physically comprising 180° opposed orifices through the wall and the control means simultaneously adjusts the area of the orifices.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A liquid control valve comprising a casing having inlet and outlet ports, wall means in said casing having a single pair of opposed spaced orifices formed therethrough, said wall means defining a chamber with an open top and bottom and unobstructed space between the opposed orifices, means directing flow from the inlet port to said orifices, second means directing flow from the top and bottom of said chamber to said outlet port, and flow control means fitted to simultaneously control the size of said pair of orifices so that each has equal cross-sectional area, said orifices directing jets at each other and being spaced apart a distance to create a stable dissipation zone within said chamber and discharging the flow from the top and bottom of said chamber with substantially spherical expansion.
Claim 2
Dependent Claim
132 words
A liquid control valve comprising a casing having inlet and outlet ports, wall means in said casing having a single pair of opposed spaced orifices formed therethrough, said wall means defining a chamber with an open top and bottom and unobstructed space between the opposed orifices, means directing flow from the inlet port to said orifices, second means directing flow from the top and bottom of said chamber to said outlet port, and flow control means fitted to simultaneously control the size of said pair of orifices so that each has equal cross-sectional area, said orifices directing jets at each other and being spaced apart a distance to create a stable dissipation zone within said chamber and discharging the flow from the top and bottom of said chamber with substantially spherical expansion.
Claim 3
Dependent Claim
47 words
A valve as in claim 1 wherein the orifices are spaced apart substantially within the range of -5% to +30% of a distance defined by the expression [1.3+0.1∛ΔP]d where ΔP equals the maximum design dissipation pressure (PSI) and d is the inlet supply port diameter in inches.
