To provide a safety valve switching system capable of easily switching a safety valve of a tank according to a type of cargo to be accommodated.SOLUTION: A safety valve switching system 10 comprises: a tank 1 that alternately stores two types of liquefied gases that have different internal pressures applied therein; a first safety valve 4 which prevents excessive internal pressure caused by the first liquefied gas, which is the gas with the lower pressure of the two types of liquefied gasses applied inside the tank 1; a second safety valve 5 which prevents excessive internal pressure caused by the second liquefied gas, which is the gas of the two types of liquefied gasses different from the first liquefied gas; and switching means that switches to select either the first safety valve 4 or the second safety valve 5 based on an internal condition of the tank 1.SELECTED DRAWING: Figure 1

    【課題】 収容される貨物の種類に応じてタンクの安全弁を容易に切り替られる安全弁切り替えシステムを提供することにある。【解決手段】 安全弁切り替えシステム10は、内部で掛けられる圧力が異なる2種類の液化ガスを入れ替えて蓄えるタンク1と、2種類の液化ガスのうちタンク1の内部で掛けられる圧力が低い方の第1液化ガスによる過剰な内部圧力を防止する第1安全弁4と、2種類の液化ガスのうち第1液化ガスと異なる第2液化ガスによる過剰な内部圧力を防止する第2安全弁5と、タンク1の内部状態に基づいて、第1安全弁4と第2安全弁5のいずれか一方を選択するために切り替える切り替え手段とを備える。【選択図】図1
