ABSTRACT:
An apparatus and method for attaching a dispersion valve to a fractionation tray surface. The valve is inserted into a fractionation tray perforation. At least two legs extend downward from a cover plate with a larger area than the perforation. Each of the legs is positioned at or near the peripheral inner surface of the tray perforation. Each leg has an outwardly projecting hooking element. As the valve is inserted into the fractionation tray perforation by pressure applied to the cover plate, the hooking elements bend inward slightly to a smaller circumferential plane than that of the tray perforation. After insertion, the flexible legs spring back to their original outwardly projection. The tip of each hooking element then contacts the bottom surface of the fractionation tray to define and limit the upward motion of the valve. At least one downward projection from the cover plate defines and limits the downward motion of the valve into the tray perforation.
