Abstract:
A liquid seal for use with low pressure gas lines. It has a U-shaped conduit and an associated reservoir with the sealing liquid therein connected to the bottom of the U. The reservoir has an overflow to maintain a desired level in the U-conduit under static conditions. The top of the reservoir is closed and is connected by a pneumatic line to a valve so that it may be connected alternatively to the down stream side of the gas seal or to the suction side of the pump which circulates the gas in the line.
