Purge/charge manifold and method for cryogenic systems |
摘要 |
A T-shaped manifold employs a single multiway control valve for purging and charging a cryogenic system of interest. The single multiway control valve is positioned at the intersection of a crossbar and perpendicular elongate member. One end of the crossbar is associated with a source of working gas. the opposite end of the crossbar provides a purge or check valve outlet. One end of the elongate member is connected to the multiway control valve and an opposite end is coupled by a VCO fitting to the cryogenic system of interest. At one setting, the single multiway control valve provides working gas to the system through the one end of the crossbar and elongate member. At a second setting, the multiway control valve allows gas to be vented from the system to ambient through the elongate member and the purge valve outlet. An in-line pressure gauge connected to the elongate member provides an indication of ingoing flow as well as outgoing flow of gas during respective charging and purging of the system. An in-line filter of the elongate member prevents particulate contamination of the flowing gases.
