| 摘要 |
<p>The invention is a relief device (100) for a high-pressure gas container (10), comprising a main body (102) having a uniform outer circumference that defines a bore (116). Within the bore (116) is a rupture disc (120) for relieving to the atmosphere the container's contents when the container (10) reaches a certain pressure. The relief device (100) is coupled to the high-pressure gas container (10) via a threaded connection (101). The bore comprises a primary bore (104) coaxial with the main body's main axis and a secondary bore (106) containing the rupture disc (120), each bore being in fluid communication with one another. An adapter (114), threaded at its upstream end to engage corresponding threads in the secondary bore (106), retains the rupture disc (120) within the secondary bore (106). A shear ring (122) between the adapter (114) and the rupture disc (120) facilitates rupturing of the rupture disc (120).</p> |
