| 摘要 |
This invention relates to an accessory device (14) for a quench valve (8) of a cryostat (1), in particular for use in a magnetic resonance imaging (MRI) system. Furthermore, this invention relates to a method of enabling a cryostat (1) containing a cryogen (3) to be safely transported by air transportation. In order to achieve this, an accessory device (14) for a quench valve (8) of a cryostat (1) is provided, said accessory device (14) being adapted to be installed to the quench valve (8), thereby raising the cracking pressure of the quench valve (8) without changing the operability of the quench valve (8). |
