PROBLEM TO BE SOLVED: To provide a hydrogen trailer capable of improving safety while reducing workload with respect to the operation of source valves, such as easiness in simultaneously closing in emergency, etc., all source valves which are provided in each of a plurality of high-pressure hydrogen vessels mounted on the hydrogen trailer.SOLUTION: In a hydrogen trailer which is transported or detained in a state in that a plurality of high-pressure hydrogen vessels A are mounted thereon, the hydrogen trailer comprises: an emergency shutdown valve 61 provided along collective piping that leads to all of the vessels A; and source valves Aa attached to each of the vessels A, in which the source valves Aa are automatically closed in drive connection with the closing of the emergency shutdown valve 61. The emergency shutdown valve 61 and each of the source valves Aa are opened/closed by nitrogen gas supplied from a common nitrogen cylinder 71 mounted on the trailer; and each of the source valves Aa is closed by the change of pressure of the nitrogen gas during the closing the emergency shutdown valve 61.

    【課題】 複数搭載された高圧水素容器のそれぞれに設けられた元弁を緊急時等に一斉に閉じることが容易であるなど、元弁操作に関する作業負担を軽減するとともに安全性を向上させた水素トレーラを提供する。【解決手段】 高圧水素容器Aを複数本搭載した状態で移送および留置される水素トレーラにおいて、容器Aのすべてに通じる集合配管に緊急遮断弁61を設けるとともに、容器Aのそれぞれに取り付けられた元弁Aaを、上記緊急遮断弁61の閉鎖に連動して自動的に閉じるものとした。緊急遮断弁61と各元弁Aaとは、トレーラ上に搭載された共通の窒素ボンベ71から供給される窒素ガスによって開閉するものとし、緊急遮断弁61を閉鎖させる際の当該窒素ガスの圧力変化によって各元弁Aaも閉じるようにした。【選択図】 図7
