摘要：: <p>An emergency disconnector for a fluid loading and unloading line, comprising, a pair of couplings (1, 2) each having a fluid passage (1a, 2a), a pair of slide valves (221, 222) axially slidably movable within said couplings and being normally held apart from one another to establish a continuous fluid path through said couplings, said slide valves including valve heads (231, 232), sealing means (241, 242) surrounding said valve heads and extending outwardly therefrom and being movable into sealing abutment with a first inner surface of said fluid passages, and a pair of cover rings (216) covering at least a portion of said sealing means when said slide valves are positioned to provide a continuous fluid path through the couplings, said cover rings defining a portion of the fluid passages, respectively mounted on inner walls defining said fluid passages and having fluid passages therein continuous with said fluid passages of said coupling. <IMAGE></p>
