Abstract
A rupturable pressure relief apparatus which is non-fragmenting and which is particularly suitable for liquid and low pressure gas service. The apparatus includes an annular rupture disk having an annular flange portion connected to a concave-convex portion by a circular transition connection. The concave-convex portion includes a groove in a side thereof creating a substantially circular line of weakness therein and at least one concave-convex hinge reinforcing member is attached to a side of the concave-convex portion of the rupture disk. The hinge reinforcing member is positioned and is of a shape whereby upon rupture of the rupture disk, the concave-convex portion tears along the line of weakness created by the groove and bends about an integral untorn portion corresponding with the hinge reinforcing member.
Claims14
A rupturable pressure relief apparatus adapted to be clamped between inlet and outlet annular support members comprising:
- a rupture disk having an annular flange portion connected to a concave-convex portion by a circular transition connection, the concave-convex portion including a groove in a side thereof creating a line of weakness therein;
- at least one concave-convex hinge reinforcing member attached to a side of said concave-convex portion of said rupture disk having a shape and positioned adjacent a portion of said concave-convex portion of said rupture disk whereby upon rupture, said concave-convex portion of said rupture disk tears along said line of weakness created by said groove and bends about an integral untorn portion corresponding with said hinge reinforcing member.
A rupturable pressure relief apparatus comprising:
- a pair of annular support members adapted to be sealingly clamped together and connected in a pressure relief area;
- a rupture disk having an annular flat flange portion adapted to be sealingly clamped between said annular support members connected to a concave-convex portion by a circular transition connection, the concave-convex portion including a substantially circular groove in a side thereof creating a line of weakness therein;
- at least one concave-convex hinge reinforcing member attached to a side of said concave-convex portion of said rupture disk having a shape and positioned adjacent a portion of said concave-convex portion of said rupture disk whereby upon rupture, said concave-convex portion of said rupture disk tears along said line of weakness created by said groove and bends about an integral untorn portion corresponding with said hinge reinforcing member.
