ABSTRACT:
A drip trap for separating a liquid from a gas includes a casing, an inlet duct near the top end of the casing for introducing a liquid-containing gas into the casing, a downspout on the inner end of the casing beneath the bottom end of the downspout for discharging liquid from the casing, and a four-way two port valve for connecting either the inlet duct to a gas line for receiving liquid-containing gas, or the outlet duct to a drain for discharging liquid from the casing. The liquid-containing gas is fed into the casing until the liquid rises above the bottom of the downspout to compress gas in the top end of the casing. The valve is rotated to close the inlet duct and open the outlet duct to the drain, whereby liquid is discharged from the casing. The trapped gas provides the driving pressure for discharging the liquid and positive prevention of continuous venting of manifold gas vapors through the trap to atmosphere. The invention further provides a method of lifting the liquid to enable gravity run to sewer line.
