Argon Dewar Relief Set Pressure Modifications

PDF Version Also Available for Download.

Description

This engineering note documents the calculations of Kelly Dixon, used to determine the maximum allowable set pressure for the argon dewar low relief valve, tag number PSV620A, Anderson Greenwood Type 526J. The original setting was 16 psig. This value was chosen in order to protect against cryostat overpressurization by the source dewar (see D0 Engineering Note 115), however, the following calculations will show that the set pressure can be raised to approximately 18.5 psig, which would result in a faster filling of the cryostat, along with a higher level of liquid argon. Three other engineering notes were revised to reflect ... continued below

Three other engineering notes were revised to reflect the change in set pressure according to this note. They are notes 115, 219, and 263.
