Problems solved by technology

On the other hand, when a material with low thermal conductivity such as carbon fiber reinforced plastic is used as the material of the high-pressure gas container body, heat is difficult to transfer to the container body.
Therefore, in the case where a part of the container is heated at a position away from the plug valve, such as the end of the container on the side opposite to the plug valve, it may take time until the heat is transferred to the plug valve.
In this case, although the temperature of a part of the container rises, the above-mentioned melting of the plug valve does not occur, and the internal pressure may increase to reduce the durability of the container.

no. 1 Embodiment approach

[0015] figure 1 It is a schematic configuration diagram illustrating the high-pressure gas container according to the first embodiment of the present invention.

[0016] The high-pressure gas container 100 of this embodiment includes: a substantially cylindrical container body 10; hubs 13-1, 13-2 disposed at both ends in the longitudinal direction of the container body 10; One hub 13 - 1 of the container main body 10 ; and a heat conductor 17 that connects the hub 13 - 1 on one side and the hub 13 - 2 on the other side inside the high-pressure gas container 100 .

[0017] Gas can be stored in a high-pressure state of 35Mpa or 70Mpa inside the high-pressure gas container 100 . Various gases are conceivable as the gas, and hydrogen gas is particularly conceivable in the present embodiment, and the high-pressure gas container 100 storing the hydrogen gas is mounted on, for example, a fuel cell vehicle.

[0018] In addition, the container main body 10 has: an inner layer body 11...

no. 2 Embodiment approach

[0042] Hereinafter, a second embodiment will be described. In addition, in each of the following embodiments, the same reference numerals are assigned to the same components as those in the preceding embodiments, and detailed descriptions will be omitted.

[0043] Figure 2A , Figure 2B It is a schematic configuration diagram of the high-pressure gas container 100 in the second embodiment of the present invention.

[0044] Figure 2A As shown, in the present embodiment, the hub portions 13 - 1 and 13 - 2 at both ends are connected by the heat conductor 17 configured as a rod-shaped metal shaft. In addition, a metallic corrugated portion 17 a serving as a displacement absorbing portion is formed at an approximately central portion in the axial direction of the heat conductor 17 . As a result, even when the container 100 undergoes deformation such as expansion, the displacement of the corrugated portion 17a is absorbed, so it is possible to suppress the concentration of loa...

no. 3 Embodiment approach

[0054] Hereinafter, a third embodiment will be described.

[0055] image 3 It is a schematic configuration diagram of the high-pressure gas container 100 in the third embodiment of the present invention. image 3 The high-pressure gas container 100 is provided with a filling flow path 30 for filling hydrogen gas at a hub portion 13-1 integrated with a plug valve 15 .

[0056] The filling flow path 30 is a flow path through which hydrogen gas supplied from an external filling device passes, and is opened and closed by an unillustrated main shut valve. In addition, in the present embodiment, the heat conductor 17 is arranged so as to intersect with the extension line C of the filling channel 30 inwardly of the inner layer body 11 . Specifically, as shown in the figure, one end 17b of the heat conductor 17 is fixed to the upper part of the inner peripheral surface of the hub 13-1 in the figure, and the other end 17c of the heat conductor 17 is fixed to the inner periphery of t...

Abstract

A high pressure gas container with a container body provided with a fusible plug valve and a boss disposed at a position differing from said fusible plug valve, wherein said fusible plug valve and the boss each have a higher thermal conductivity than the container body, the fusible plug valve and the boss are connected by a thermal conductor, and the thermal conductor is housed inside the container body.

Description

technical field [0001] The present invention relates to a high-pressure gas container equipped with a plug valve and a method for manufacturing the high-pressure gas container. Background technique [0002] When a high-pressure gas container is exposed to a high-temperature environment, it is known to install a melt valve in the container in order to reduce the pressure in the container. A plug valve is a valve made up of the following components: a housing that is integrated with the hub (Japanese: ボス口) of the container that becomes the inflow and outflow of high-pressure gas, and has a flow path that penetrates the inside and outside of the container; plug, which closes the flow path. Thrombolytics are composed of metals with low melting points, and through exposure to high temperatures, thrombolytics melt. Thereby, even when the container is exposed to a high-temperature environment, the high-pressure gas in the high-pressure gas container is released to the outside thr...
