Abstract
A liquid separator ( ) for separating two immiscible liquids having different specific gravities, for example, a first liquid comprising water and a second liquid comprising oil. The liquid separator ( ) has a housing ( ) that defines a separation chamber ( ) and liquid inlet ( ), a first liquid outlet ( ) and a second liquid outlet ( ) mounted above the first liquid outlet ( ). A float is positioned within separation chamber to translate in the vertical direction and has a specific gravity between that of the first and second liquids so that it floats at approximately the interface ( ) between the two liquid phases ( and ). Valve closure devices ( and ) contact valve seats in the valves and of first and second liquid outlets ( and ) to control the flow of separated liquids from separation chamber as determined by the level of the interface ( ) and the length of the valve rods ( and ).
