A cracking pressure raising device 14, features a main body 15, a spring arrangement 24, a number of spring elements 26, and attachments means 22. The device 14 in use is attached to a container valve 9, the spring elements 26 bearing down upon the valve 9, thereby raising a cracking pressure of the valve 9. The container 2 may be a cryostat container 2 of liquid helium for the superconducting magnets of an MRI scanner. Placing the device 14 on the container 2 before air transport of the cryostat container 2, may reduce the chance of the valve 9, opening or bursting, under the reduced pressure transport conditions of an aircraft storage hold. |
