An overfill prevention valve system comprises: an overfill prevention valve (32) including: a fluid path (44); a blocking component (42) positioned in the fluid path (44), wherein said blocking component (42) is movable between a closed position wherein the blocking component (42) generally blocks fluid from flowing through the fluid path (44) and an open position wherein the blocking component (42) generally allows fluid to flow through the fluid path (44); and a float (38') operatively coupled or coupleable to the blocking component (42) and positioned or positionable externally of said fluid path (44), characterised in that said valve (32) is manually testable by magnetically moving said float (38') to thereby move the blocking component (42) away from the open position.

A liquid delivery system for supplying liquid from a portable container to a destination and removing vapor from the destination comprises a portable container, an elongate flexible liquid delivery hose, and an elongate flexible vapor recovery hose. The liquid delivery hose receives liquid from the portable container, and delivers the received liquid to a remote destination. The vapor recovery hose receives vapor from the remote destination, and delivers the received vapor to the substantially hollow interior of the portable container. The liquid delivery hose and the vapor recovery hose permit the movement of the liquid outlet of the liquid delivery hose to more than one selected remote destination while the container remains substantially stationary. Reduced air pressure in the portable container resulting from the removal of the liquid therefrom, causes vapor to be suctioned via the vapor recovery hose into the portable container.

A system and method enable intelligent refuelling of a pressurised vessel. The method includes receiving a gas at a refuelling port, wherein the refuelling port is coupled to the pressure vessel; determining a temperature 5 of the pressure vessel; determining a pressure of the pressure vessel; directing the gas through a nozzle, wherein the pressure vessel and nozzle are thermally coupled such that Joule-Thomson expansion of a gas flowing through the nozzle cools an interior cavity of the pressure vessel; and controlling a shut-off valve according to an amount of gas in the pressure 10 vessel determined according to the temperature and pressure, wherein the shut-off valve is located between the refuelling port and the pressure vessel, for controlling a flow of gas between the refuelling port and the pressure vessel.

A monitoring system for use when loading fluid to or from a rail tanker via a loader apparatus (206), the monitoring system having: a track electrical connector for coupling to a rail track (210); a tank electrical connector for coupling to a tank (204) on a rail car (216); a loader electrical connector for coupling to the loader apparatus (206); and circuitry configured to determine a status of an electrical continuity between the tank (204) on the rail car (216), the rail track (210) and the loader (206). Determining the status of the electrical continuity includes verifying that the electrical continuity is adequate to provide grounding.
摘要:
An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir and a structure for securing drop tube segments are described. The overfill valve includes a valve body positioned within the drop tube segment and, in certain embodiments, a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. A variety of internal actuators are used to actuate the valve body within the drop tube segment. The structure for securing drop tube segments provides a first drop tube segment with a groove into which the wall of a second drop tube segment can to deformed to seal and fasten the two drop tube segments to each other.
