Shut-off valve

The invention provides a shut-off valve (10) for a hydrocarbon liquid or fuel intake. The valve includes a first float body (14) configured to float at the surface of hydrocarbon fuel (15), a fuel intake (16) located on the first float (14) and positioned such that the intake (16) is below the surfa...

Beschreibung
Zusammenfassung:	The invention provides a shut-off valve (10) for a hydrocarbon liquid or fuel intake. The valve includes a first float body (14) configured to float at the surface of hydrocarbon fuel (15), a fuel intake (16) located on the first float (14) and positioned such that the intake (16) is below the surface of the fuel (15), in use, and a second float body (18) configured to float on water (20) and sink in hydrocarbon fuel (15) such that the body (18) floats at an interface of hydrocarbon fuel (15) and water (20) phases, in use. A closing means (24) is located on the second float (18) for closing or restricting the fuel intake (16) when the first float (14) and second float (18) are in contact or in close proximity and further includes a guide arrangement (26) for guiding the first and second float (14, 18) towards each other as the surface of the hydrocarbon fuel (15) approaches the fuel water interface.
