Abstract
A device for restricting liquid backflow through an overhead line on a tank and a method of using the device are provided. The device has a tubular housing with spaced internal baffle plates. The device is secured in place in the interior of an overhead pipe on the top of a tank on a tank truck or other vehicle used for transporting bulk liquid cargo. The device prevents liquid backflow from entering overhead piping due to sloshing action of the liquid during transport. The device allows air to flow through the device so that air may be supplied to the tank, as well as vented from the tank, through the device.
Claims17
A device for restricting liquid backflow through an overhead line on a tank, said device comprising a tubular housing and a plurality of baffle plates disposed within an interior of the housing, wherein each baffle plate has at least one aperture therethrough, wherein the device has flexible supports configured to removably secure the device in a fixed position within an interior of a pipe, wherein the supports are attached to an exterior surface of the tubular housing, and wherein the supports are resiliently biased in an outward radial direction.
A method of restricting liquid backflow through an overhead line on a tank secured to a transport vehicle, said method comprising the steps of:
- providing a device configured to removably secure the device in a fixed position within an interior of a pipe, said device comprising a tubular housing and a plurality of baffle plates disposed within an interior of the housing,
- wherein each baffle plate has at least one aperture therethrough;
- and
- installing the device within an interior of a pipe connected to a top side of a tank and in fluid communication with an interior of the tank.
