Fail safe retaining plug assembly for a slam-shut safety device |
摘要 |
A fail safe retaining plug assembly for a slam-shut safety device includes a reset pin, a retaining plug attached to the reset pin at a proximal portion, and a safety disk attached to the reset pin at a distal portion. The retaining plug assembly is sufficiently long to prevent the safety disk from falling off of the distal portion before the safety disk contacts a valve seat. The retaining plug assembly is also sufficiently long to prevent the retaining plug from falling off of the reset pin before the safety disk contacts the valve seat. |
