Emergency disconnector for fluid loading and unloading lines

摘要

An emergency disconnector for a fluid loading and unloading line, comprising; a pair of couplings (1, 2) having joint openings and fluid passages (113, 114) a pair of sliders (127, 128) axially slidably disposed in said couplings and having a pair of valve heads (133, 134) from which spacer means extend toward one another, means for biasing said sliders toward said joint openings, said sliders being movable by said biasing means into said joint openings to cut off said fluid passages. The sliders are shaped such that they provide a space of a substantially uniform cross-sectional configuration between inner surfaces of said couplings and said sliders. Each slider includes guide rings (143, 144) and outer barrels (3, 4) of the couplings have enclosing rings (125, 126). Fluid reservoirs are defined by an inner wall of the outer barrels, said guide rings, said enclosing rings and an outer surface of the sliders.
