Abstract:
A full-flow failsafe, comprising:a reaction tube for containing a flowing fluid stream; a first shell having first apertures at each end thereof for enabling said fluid stream to flow therethrough, a first one of said first apertures being coupled to said reaction tube; a first sealing plug movably positioned within said first shell, said first sealing plug being oriented in a first position during normal operation of said reaction tube to permit fluid flow through said first shell, and being moved by increased fluid velocity to a second position wherein said first sealing plug forms a sealing contact with a second one of said first apertures, upon failure or breakage of said reaction tube; and at least one first locking mechanism supporting said first sealing plug in said first position, and being moved to a locking position for securing said first sealing plug in said second position in response to said movement of said sealing plug.
