Abstract
This disclosure relates to a rupture disk (400), which may include a flange portion (401), a reverse-buckling dome portion (403), and a transition portion (402) joining the flange portion to the reverse-buckling dome portion. The dome portion may define an apex. The dome portion may further define an indentation (404) at the apex and/or a line of weakness (405), which may be proximate to the transition portion and/or may include a relatively weak segment configured to initiate rupture. An integral stress concentrating feature may be provided. A line of weakness and/or a base of a domed portion may be non-circular. The disclosure also relates to a rupture disk crimped into a holder (410). The disclosure also relates to a container having a wall that defines a rupturable portion.
Claims25
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines an apex, and wherein the dome portion further defines an indentation at the apex;
- wherein the dome portion further defines a line of weakness.
A rupture disk assembly, comprising:
- a rupture disk, the rupture disk having a flange portion and a reverse-buckling dome portion;
- and
- a holder, wherein the holder is configured to crimp the rupture disk into position within the holder.
A sealed container, comprising:
- at least one container wall;
- wherein the at least one container wall defines a rupturable portion.
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines an apex, and wherein the dome portion further defines an indentation at the apex;
- wherein the dome portion further defines a line of weakness proximate to the transition portion;
- and
- wherein the line of weakness is configured to include a relatively weak segment;
- wherein the dome portion is configured to initiate rupture at the relatively weak segment upon reversal.
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines an apex, and wherein the dome portion further defines an indentation at the apex;
- wherein the dome portion further defines at least one line of weakness, wherein the at least one line of weakness is non-circular, eccentric to a diameter of the rupture disk, angular, or a combination of curved and angular.
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines at least one line of weakness, wherein the at least one line of weakness is non-circular, eccentric to a diameter of the rupture disk, angular, or a combination of curved and angular.
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion having a base;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines an apex, and wherein the dome portion further defines an indentation at the apex;
- wherein the base of the dome portion is non-circular.
A rupture disk, comprising:
- a flange portion;
- a reverse-buckling dome portion;
- and
- a transition portion joining the flange portion to the reverse-buckling dome portion;
- wherein the dome portion defines an apex, and wherein the apex is offset from a central radial diameter of the rupture disk;
- wherein the dome portion further defines a line of weakness, wherein the line of weakness is non-circular.
