Abstract

PURPOSE:To prevent heat transfer by radiation, and prevent heat to be transferred to liquefied gas by installing plural number of buffle plates to the vacuum insulated joint in pump supporting cylinder inserted in a gas tank. CONSTITUTION:A liquified gas tank 1 filled with liquefied gas such as nitrogen gas, etc., is consisted of vacuum insulated wall 2, and the pump supporting cylinder 3 inserted into the gas tank 1, is fixed to the gas tank 1. The vacuum structure insulation joint 6 inserted in the supporting cylinder 3 of the pump 7 has plural number of buffle plates 61 installed in the interior. This prevent heat transfer by radiation, consequently prevent heat transfer to the liquefied gas.
