Safety
Quench Valve
The quench valves (5) are the safety devices of the helium vessel. They open with a
defined pressure. In case of an accidental overpressure in the helium vessel the quench
valves will release the pressure smoothly.
Safety Valve
The safety valve (3) is the safety device of the nitrogen vessel. It opens with a defined
pressure. In case of an accidental overpressure in the nitrogen vessel the safety valve
will release the pressure smoothly.
Drop-off Plate
The drop-off plate (1) is a safety device of the RT vessel. If the vacuum breaks, the
drop-off plate will open. In case of an accidental overpressure in the RT vessel the
drop-off plate will release the pressure smoothly.
One-way Valves
The one-way valves of the nitrogen flow system (2) and the helium flow system (4) keep
air and moisture from entering the helium or the nitrogen vessel in case of an accidental
underpressure inside the vessels.
