The results showed that tooth edge guide floating valve plate pilot holes to increase the bottom plate of the gas-rate has a significant role to guide holes makes it tooth edge guide floating valve of the liquid valve and areas in the vicinity of the gas-liquid-quality dead-elimination.

The experimental result indicated that, the tooth guides the float valve column tray the guidance hole to increase the column tray base the gas including rate to have the vital role, the guidance hole causes the tooth to guide the float valve nearby the back fluid valve leg the region gas fluid mass

Experimental results show that the pilot hole of tooth edges directed valve trays for increased gas holdup plays an important role at the bottom of the tray, pilot hole makes the tooth edges directed valve back valve of gas-liquid mass transfer dead zone near the leg eliminated;
