ABSTRACT:
Valve for separating liquids out of gases, as in gas-well-to-customer operations, being an improvement of the valve described in our U.S. Pat. No. 3,769,999 of Nov. 6, 1973, entitled "Liquid Separator System and Apparatus". The valve comprises a body with enlarged inlet chamber, a rising passage communicating therewith, a circumferential groove about the rising passage, downwardly-extending passages spaced on opposite sides of the rising passage and extending to an outlet chamber. The valve includes a head chamber with floating disc positioned within the same and seating atop the rising passage and circumferential groove, the floating disc being provided on the underside thereof with a radial groove to bleed off fluid in the head chamber and one or more further grooves to control fluid coming from the rising passage. A spring also is positioned within the head chamber, eccentrically pressing on the disc to permit instantaneous filling of head chamber under gas operation and quick closing of the valve under head pressure. An outlet fitting engages the valve in communication with the outlet chamber, the fitting being provided with central orifice to effect desired back pressure under gas operation.
