Abstract
An improved replaceable carbon rupture disk element and element-holder assembly are provided. The carbon rupture disk element is comprised of a carbon disk having a pair of opposing bores extending thereinto whereby an integral blow-out portion having a particular rupture pressure is formed in the disk connected to an enlarged rim portion. A reinforcing ring is attached to the rim of the carbon disk having a height substantially equal to or greater than the height of the enlarged rim portion of the disk which prevents the rim portion from being subjected to compressive forces which change the rupture pressure of the blow-out portion.
Claims20
An improved replaceable carbon rupture disk element comprising:
- a carbon disk having opposite faces, a rim and a pair of opposing bores extending through said faces and into said disk, each of said bores having a depth less than half the distance between said faces whereby an integral blow-out portion having a particular rupture pressure is formed in said disk connected to an enlarged rim portion;
- and
- a reinforcing ring attached to said rim of said disk and being of a height substantially equal to or greater than the height of said rim portion whereby when said reinforcing ring and said disk are clamped between holders or flanges, said reinforcing ring prevents said rim portion of said disk from being subjected to compressive forces which change said rupture pressure of said blow-out portion.
An improved replaceable carbon rupture disk element comprising:
- a carbon disk having opposite parallel faces, a circular rim and a pair of opposing cylindrical bores extending through said faces and into said disk, each of said bores having a depth less than half the distance between said faces whereby an integral circular blow-out portion having a particular rupture pressure is formed in said disk connected to an enlarged rim portion;
- and
- a reinforcing ring attached to said rim of said disk and being of a height substantially equal to or greater than the height of said rim portion whereby when said reinforcing ring and said disk are clamped between holders or flanges, said reinforcing ring prevents said rim portion of said disk from being subjected to compressive forces which change said rupture pressure of said blow-out portion.
An improved carbon rupture disk assembly comprising:
- a replaceable carbon rupture disk element comprised of:
- a carbon disk having opposite faces, a rim and a pair of opposing bores extending through said faces and into said disk, each of said bores having a depth less than half the distance between said faces whereby an integral blow-out portion having a particular rupture pressure is formed in said disk connected to an enlarged rim portion, and
- a reinforcing ring attached to said rim of said disk and being of a height substantially equal to or greater than the height of said rim portion whereby when said reinforcing ring and said disk are clamped between holders, said reinforcing ring prevents said rim portion of said disk from being subjected to compressive forces which change said rupture pressure of said blow-out portion;
- and
- a pair of annular holders adapted for sealingly clamping said rupture disk element therebetween.
