Abstract
An emergency line disconnector for an LNG loading/unloading line or the like is made capable of accommodating bi-directional fluid flow. Sliders within the fluid passageways are arranged such that a substantially uniform cross-sectional flow path is provided for the fluid. Sealing devices are mounted on the sliders to cut off fluid flow through the device, and such devices are designed so as to be resiliently operable at the extremely low temperatures of LNG. To dissipate the fluid shock due to rapid closure of the device, a fluid shock absorber employing restrictive passageways may be used to slow the advance of the sliders to their cut-off positions.
