Abstract
A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.
Claims9
A valve assembly, comprising:
- a sleeve member having a top, a fluid inlet, a length, an inner chamber, and a bottom having an opening extending into said inner chamber;
- a sealing component disposed in the sleeve member and configured to create a fluid pressure seal that prevents fluid flow through an opening;
- a float member slidably disposed in said inner chamber;
- and
- a linkage assembly disposed between said float member and the sealing mechanism, wherein said linkage assembly is configured remove said fluid pressure seal when said float member reaches a predetermined position along the length of said sleeve member in response to a liquid reaching a predetermined level in a container.
