摘要： A gas-liquid contact tray having a substantially planar deck, a plurality of apertures extending through the deck, and a plurality of valve covers disposed over the apertures. The deck has an upper surface and a lower surface. Each of the valve covers has a cover plate and a first leg extending between the cover plate and the deck for supporting the cover plate over the upper surface of the deck. The cover plate has a perimeter edge having a plurality of alternating extensions and depressions. During operation of the tray a vapor ascends through the apertures and fluid is deposited onto the tray, the fluid flowing across at least a portion of the deck and contacting the ascending vapor, and the fluid thereafter exiting off of the tray. A process for the manufacture of a gas-liquid contact tray, the process: providing a substantially planar deck having an upper surface and a lower surface; and punching the deck to substantially simultaneously create apertures through the deck and valve covers disposed substantially above the apertures. Ones of the valve covers have a cover plate and a first leg extending between the cover plate and the deck for supporting the cover plate over the upper surface of the deck. The cover plates having a perimeter edge having a plurality of alternating extensions and depressions.
