Abstract
The present disclosure concerns an overpressure relief system that can be affixed to an enclosed vessel and provide an exhaust therein if the pressure exceeds a prescribed amount. The system functions by selection of a moveable weight that covers a pressure relief channel in connection with the vessel. As pressure passes a threshold, the weight is shifted upwards within the system, allowing the pressure relief channel to connect to an outlet. Overpressure may then be relieved through the outlet and the weight returns to close access to the outlet.
Claims24
An overpressure relief system for use in a pressurized vessel comprising:
- a pressure relief channel comprising an end adapted to connect to a pressurized vessel;
- a shell comprising a void volume within the shell;
- a moveable weight within said void volume, wherein at least a portion of the weight fills the shell in a radial direction and is moveable in an axial direction through the void volume when in contact with an overpressure through the pressure relief channel from the pressurized vessel;
- and,
- an outlet;
- wherein the movement of the weight allows fluid communication between the pressure relief channel and the outlet to allow overpressure to escape from the pressurized vessel through the outlet.
A method for relieving overpressure in a pressurized vessel or system comprising:
- contacting an overpressure from a pressurized vessel with an overpressure relief system comprised of a pressure relief channel, a weight, and an outlet, wherein the outlet is blocked by the weight,
- wherein overpressure moves the weight in an axial direction from a first position through a void volume,
- wherein the movement of the weight allows overpressure to escape from said vessel through the outlet;
- and
- wherein the weight moves back to the first position after the overpressure escapes.
