    • PROBLEM TO BE SOLVED: To eliminate irregularity in a gas seal tank by stabilizing inner pressure of seal gas in a tank for storing contained volatile fluid such as petroleum-based fluid or chemical fluid by use of an inner pressure regulating device of simple structure.
      SOLUTION: This gas seal tank comprises the inner pressure regulating device N disposed in a seal gas supply passage between the tank 1 for storing contained fluid 2 such as volatile fluid to be sealed with seal gas G and a seal gas pressure regulating valve 3 opened/closed based on detected seal gas pressure for regulating pressure of seal gas supplied to the tank. The inner pressure regulating device comprises a main body part roughly in three-way pipe structure, having a first connection port 3a on one end side, a second connection port 3b toward the tank side on the other end side, and a third connection port 3c connected in the middle to a detecting part 17 of the seal gas pressure regulating valve through control piping 22, a partition pipe 5 of which one end 5a is fixed to an inner wall of the first connection port, and the other end 5b faced as a free end to the second connection port, so as to part the inside of the main body part to an inner chamber 6A and an outer chamber 6B, and a flow restricting means 7 provided in a connection passage between the third connection port and the outer chamber.
