Abstract
A solenoid driven valve is disclosed which is adaptable for controlling the introduction of a high pressure fluid into a fluid trapping assembly having an absorption column topped with an annular orifice expansion nozzle. The valve has an inlet port to introduce high pressure fluid, an axially moving solenoid driven pin which engages means to restrict fluid flow into said column. A diaphragm is located within the valve to direct fluid into the column and which separates the fluid in a region of high pressure from ambient pressures.
Claims7
In a method of conducting fluid under high pressure into a column for removing and collecting solute component of said fluid, the steps comprising:
- introducing said fluid under high pressure through axially driven valve means into an annular orifice expansion nozzle atop said column, wherein said valve means is driven and includes an axially moving pin adapted to restrict the flow of said fluid through said valve means by closing said orifice expansion nozzle, and
- expanding said fluid into said column under reduced pressure.
