Abstract
There is provided herein an improved rupture panel or disk that consists of a sheet metal top section with a relatively thick polymer foam seal attached thereto. In the preferred arrangement the instant invention does not require a separate support member. The foam sealing component is preferably attached to the top section by some sort of adhesive to hold it in place and it is installed on the process side of the top section. Additionally, the sealing member is preferably of a thickness which is substantially thicker than would typically be used in a conventional rupture panel arrangement. In another preferred embodiment the sealing member is also designed to function as a gasket, thereby eliminating the need for that separate member.
Claims23
A pressure relief device for use with a pressure system containing fluid therein, comprising:
- (a) a thin metal top section, said top section having at least one weakening slit penetrating therethrough, said top section having a pressure side, said pressure side being positionable to be in fluid communication with said pressure system;
- and,
- (b) a foam seal affixed to said top section on said pressure side of said top section, said foam seal covering all of said at least one slits, thereby preventing the flow of fluid therethrough.
A pressure relief device for use with a system containing fluid therein, comprising:
- (a) a metal top section, said metal top section having at least one weakening slit placed therethrough, said top section having a process side, said process side being positionable to face said fluid in said system;
- and,
- (b) a foam seal adhered to said top section on said process side of said top section, said foam seal covering all of said at least one slits,
- wherein said foam seal is for preventing said fluid from passing though said at least one slits, and,
- wherein at least one-of said at least one slits does not have a slit cover positioned between said slit and said seal.
A pressure relief device for use with a pressure system containing fluid therein, comprising:
- (a) a thin metal top section, said top section having at least one weakening slit penetrating therethrough, said top section having a pressure side, said pressure side being positionable to be in fluid communication with said pressure system;
- and,
- (b) a foam seal affixed to said top section on said pressure side of said top section, said foam seal covering at least one of said at least one weakening slits, thereby preventing the flow of fluid therethrough.
