Abstract
The invention relates to a pressure relief device and to a method for producing a pressure relief device, the pressure relief device (10) comprising a rupture disc (11) and a vacuum support (12, 32), the rupture disc and the vacuum support being made of graphite, the one-piece rupture disc having an exit side (13) and an entry side (14), the rupture disc having a recess (15) on the entry side, said recess (15, 33) forming a rupture area (17) within a retainer (16) of the rupture disc, the vacuum support being inserted in the recess, the pressure relief device having a carbon retaining device (30) for a form-fitted fastening of the vacuum support in the recess.
Claims14
A pressure relief device (10), comprising a rupture disc (11, 31) and a vacuum support (12, 32), the rupture disc and the vacuum support being made of graphite, the rupture disc having an exit side (13) and an entry side (14), the rupture disc having a recess (15, 33) on the entry side, said recess (15, 33) forming a rupture area (17) within a retainer (16) of the rupture disc, the vacuum support being inserted in the recess, characterized in that the pressure relief device has a carbon retaining device (30) for a form-fitted fastening of the vacuum support in the recess;
- wherein the retaining device (30) is made of a groove in an inner surface of the retainer (16) and a retaining element (28) inserted in the groove, and wherein the retaining element (28) is a string, braid, cord or band made of carbon fibers.
A method for producing a pressure relief device (10), a rupture disc (11, 31) and a vacuum support (12, 32) of the pressure relief device being made of graphite, the rupture disc being made in one piece having an exit side (13) and an entry side (14), a recess (15, 33) being formed on the entry side of the rupture disc and forming a rupture area (17) within the retainer (16) of the rupture disc, the vacuum support being inserted in the recess, characterized in that a retaining device (30) of the pressure relief device is made of carbon, the vacuum support being fastened in the recess in a form-fitted manner by means of the retaining device;
- wherein the retaining device (30) is made of a groove in an inner surface of the retainer (16), wherein a retaining element (28) is inserted in the groove, and wherein the retaining element (28) is a string, braid, cord or band made of carbon fibers.
