Fire suppression system actuation apparatus and system

摘要

A fire suppression system may comprise a shape memory actuation system. The shape memory actuation system may be configured as a retainer that retains a plug and/or a disk. The shape memory actuation system may be a shape memory plug that is configured to discharge from a vessel exhaust port. The shape memory actuation system may be deployable in response to an electrical stimulus (e.g., resistive heating causing the shape memory alloy to have a temperature exceeding a transition temperature).

主权项

1. A fire suppression system, comprising:
a vessel having an opening and configured to contain a pressurized fire suppression agent; a disk configured to seal the opening of the vessel and retain the pressurized fire suppression agent; a plug configured to block the opening of the vessel and to support and retain the disk; a retainer configured to constrain the plug and to non-destructively change shape in response to a change in temperature such that the plug moves relative to the disk and the pressurized fire suppression agent ruptures the disk in response to the plug moving relative to the disk; and an exhaust port configured to direct a flow of fire suppression agent in response to the disk rupturing.
