Purgeable connection for gas cylinders.

摘要

A device and a method for its use for the removal of contaminants from a gas cylinder valve assembly (63). The valve assembly output is fed to the device which in turn has inlet (61) and outlet (66) connections to receive and to pass purge gas therethrough. The device is sized and positioned so that contaminants can be purged and a vacuum drawn from the gas cylinder valve assembly at the assembly location itself thus increasing the efficiency of contaminant removal.
