However, when used for underwater exploration vessels, the tank internal pressure rises due to boil-off, and even if a safety valve operates, the tank internal pressure is reduced outside the tank. If the pressure is not higher than the water pressure, the oxygen gas will not be discharged out of the tank. For this reason, the pressure resistance of the oxygen tank needs to be equal to or higher than the water pressure corresponding to the diving depth of the underwater vehicle.

It has a pressure resistance of 40 kg / cm 2 to withstand the water pressure of 00 m, but the inner shell 3 has a pressure resistance of 11 kg / cm 2 to withstand the working pressure of the filled liquid oxygen a. The outer shell 2 has a pressure resistance enough to withstand a predetermined vacuum pressure, that is, 1 kg / cm 2 . Further, each of the pressure-resistant shell 1, the outer shell 2, and the inner shell 3 has one or two relief valves. The pressure proof shell 1 has a fourth relief valve 9 in the middle of a pipe 13 having an opening outside the pressure proof shell. The relief valve 9 is set to operate when the internal pressure of the pressure shell 1 becomes higher than the external water pressure. In addition, outer shell 2
Has a third relief valve 8 in the middle of a tube 12 having an opening in the pressure shell 1. The operating pressure of this relief valve 8 is 1 kg
/ Cm 2 . Furthermore, the inner shell 3 has a second relief valve 7 (operating pressure 11 kg / cm 2 ) in the middle of a pipe 11 having an opening in the outer shell 2 and a middle of a pipe 10 having an opening outside the pressure-resistant shell. It has a first relief valve 6. The operating pressure of the relief valve 6 is set at 10 kg / cm 2 .

３内から耐圧殻１外に酸素ガスが直接、放出される。Next, the operation of the above-described liquid oxygen tank will be described. When the underwater exploration ship A is in a shallow sea below 100 m in depth, the liquid oxygen a in the inner shell 3 is boiled off and the pressure in the inner shell 3 is increased to the operating pressure of the first relief valve 6 (10 kg / cm).
2 ) When the pressure is increased above, the first relief valve 6 is opened, and oxygen gas is directly discharged from the inside of the inner shell 3 to the outside of the pressure-resistant shell 1.

了する。On the other hand, when the underwater exploration vessel A is in the deep sea at a depth of 100 m or more, the liquid oxygen a in the inner shell 3 is boiled off, and the pressure in the inner shell 3 is reduced to the operating pressure of the first relief valve 6 (10
Even if the pressure rises to over kg / cm 2 ) and the first relief valve 6 operates, oxygen gas is not released because the water pressure outside the pressure-resistant shell 1 is higher. Further, when the pressure rises and the pressure in the inner shell 3 rises above the operating pressure of the second relief valve 7 (11 kg / cm 2 ), the second relief valve 7 opens and oxygen gas in the inner shell 3 is released. Released into the space 4 between the shell 3 and the shell 2,
The space 4 between the inner shell 3 and the inner shell 3 ends its role as a vacuum heat insulating layer.

が図れることになる。As described above, when the oxygen gas in the inner shell 3 is released into the space 4 between the inner shell 3 and the outer shell 2, the third relief valve 8 provided in the outer shell 2 opens, and the inner shell 3 opens. Oxygen gas is released into the pressure-resistant shell 1 through the pipe 12 while maintaining the inner and outer pressures of the shell 3 and the outer shell 2 at an equal pressure. For this reason, the strength of the inner shell 3 and the outer shell 2 only needs to have the pressure resistance at the time of normal use, and the weight can be reduced.

The relief valve 9 is opened, and the oxygen gas is released outside the pressure shell 1, thereby preventing the pressure shell 1, the outer shell 2 and the inner shell 3 from being broken. In the above description, the case where the second relief valve 7 is disposed in the space 4 between the outer shell 2 and the inner shell 3 has been described. However, since the gap between the outer shell 2 and the inner shell 3 is narrow, As shown in FIG. 3, the second relief valve 7 is disposed inside the pressure-resistant shell 1, and the rupture desk 1 is used instead of the third relief valve 8.
8 may be provided on the outer shell 2.

Further, as shown in FIG. 5, the outer shell 2 may be omitted, and a double structure of the pressure-resistant shell 1 and the inner shell 3 may be adopted. On the other hand, the pressure resistance of the pressure shell 1, the outer shell 2, and the inner shell 3 is one example, and is not limited thereto.
