[0034] Figure 1 and Figure 2 A pressure gas storage tank according to the present invention is shown, which includes a thermoplastic tank barrel 100 and a seal 110. The seal 110 includes a disc body 111, an inner ring sheet 112, and an outer ring sheet 113. The inner ring sheet 112 and the outer ring sheet 113 are connected to the disc body 111 and protrude from the disc body 111 along the axial direction Z of the disc body 111. The outer ring sheet 113 is located outside the inner ring sheet 112 along the radial direction D of the disc body 111. The disc body 111, the inner ring sheet 112, and the outer ring sheet 113 are configured to form a receiving groove 115 for receiving the end of the thermoplastic tank barrel 100.

[0035] The end of the thermoplastic canister 100 is connected to the can seal 110 by heat-melting, and the outer ring sheet 113 and the outer side wall of the can seal 110 form a sealed cavity 130 for accommodating the sealing member 120 .

[0036] The pressure gas storage tank of the present invention adopts a thermoplastic barrel 100 and a tank seal 110 for installation, has good sealing performance and is suitable for gas storage. The thermoplastic barrel 100 has low production cost, light weight, and is easy to carry and install.

[0037] like Figure 1 As shown, before the pressure gas storage tank is installed, the thermoplastic tank barrel 100 is cylindrical, and the tank seal 110 can be made of metal, such as copper or steel. Figure 1 As can be seen, the disc 111, inner ring 112, and outer ring 113 of the can seal 110 form a receiving groove 115. Before the thermoplastic can 100 and the can seal 110 are heat-fused together, the end of the thermoplastic can 100 is inserted into the receiving groove 115. After the thermoplastic can 100 and the can seal 110 are heat-fused together, a sealed connection is achieved between the thermoplastic can 100 and the can seal 110. Because the inner ring 112 and the outer ring 113 are located on the inner and outer sides of the thermoplastic can 100, respectively, the sealing between the can seal 110 and the thermoplastic can 100 is further enhanced.

[0038] Reference Figure 2 After the end of the thermoplastic can 100 is hot-melt connected to the can seal 110, the end of the thermoplastic can 100 is hot-melt filled in the sealed cavity 130, thereby forming an outer edge 101, and the sealed cavity 130 is formed between the outer edge 101, the outer ring sheet 113 and the outer side wall of the thermoplastic can 100.

[0039] Optionally, the sealing cavity 130 is located outside the thermoplastic barrel 100 along the radial direction D, so that the sealing member 120 can be installed outside the thermoplastic barrel 100 , which facilitates the installation of the sealing member 120 .

[0040] Furthermore, the outer edge 101 protrudes from the outer wall of the thermoplastic barrel 100 along the radial direction D and is connected to the inner wall of the outer ring piece 113, so that the thermoplastic barrel 100 and the outer ring piece 113 are sealed and connected with good airtightness.

[0041] Furthermore, the edge of the outer ring piece 113 away from the disk body 111 is hot-melt connected to the outer wall of the thermoplastic barrel 100, thereby forming a sealed cavity 130 together with the outer edge 101 and the outer wall of the thermoplastic barrel 100, so that the sealed cavity 130 for installing the seal 120 is spaced apart from the end face of the thermoplastic barrel 100, thereby forming multiple sealing structures between the thermoplastic barrel 100 and the can seal 110, further improving the sealing between the thermoplastic barrel 100 and the can seal 110.

[0042] Optionally, the sealed cavity 130 extends around the axis of the thermoplastic can 100 and surrounds the thermoplastic can 100. In a direction away from the disc 111, the outer ring piece 113 is inclined to the outer side wall of the thermoplastic can 100, so that the cross-section of the sealed cavity 130 is a right triangle. When the end of the thermoplastic can 100 is inserted into the receiving groove 115, the outer ring piece 113 is forced to expand and contract and is pressed against the outer side wall of the thermoplastic can 100. After the thermoplastic can 100 is subsequently heat-soldered, the sealed cavity 130 is formed. Optionally, after the thermoplastic can 100 and the can seal 110 are assembled, the thermoplastic can 100 can be heat-soldered, so that the outer side wall of the end of the thermoplastic can 100 is configured to form an outer edge 101 and connected to the outer ring piece 113, ensuring the sealing between the thermoplastic can 100 and the can seal 110. The thermoplastic can barrel 100 and the outer ring sheet 113 can be sealed by gluing, thereby further ensuring the sealing between the thermoplastic can barrel 100 and the can seal 110 .

[0043] Optionally, the pressure gas storage tank includes at least one seal 120, which can be a sealing ring and is sleeved onto the outside of the thermoplastic tank barrel 100. When the thermoplastic tank barrel 100 and the tank seal 110 are hot-melt connected, the seal 120 is respectively connected to the outer wall of the thermoplastic tank barrel 100 and the inner wall of the outer ring sheet 113, thereby further enhancing the sealing performance of the pressure gas storage tank.

[0044] Reference Figure 2 Optionally, along the axial direction Z of the disc body 111, at least one side wall of the inner ring piece 112 is inclined toward the outside, so that after the thermoplastic can 100 is inserted into the accommodating groove 115, the inner ring piece 112 can be pressed against the inner side wall of the thermoplastic can 100, so that the inner ring piece 112 and the inner side wall of the thermoplastic can 100 are sealed. After the subsequent hot melt treatment of the thermoplastic can 100, the sealing between the thermoplastic can 100 and the can seal 110 can be further strengthened.

[0045] Reference Figure 2 The pressure gas storage tank includes two tank seals 110 , which are respectively arranged at both ends of the thermoplastic tank barrel 100 .

[0046] As an alternative, the pressure gas storage tank may include only one pot seal 110 , and the thermoplastic tank barrel 100 may be open at one end, with the pot seal 110 being disposed at the open end of the thermoplastic tank barrel 100 .

[0047] Furthermore, at least one of the tank seals 110 is provided with a pressure relief valve 114, thereby preventing the gas pressure in the pressure gas storage tank from being too high and facilitating the injection of gas into the pressure gas storage tank.

[0048] Optionally, the pot seal 110 is constructed as a metal component and the thermoplastic can 100 is constructed as a fiber-reinforced thermoplastic resin component, thereby facilitating assembly and heat-melting connection between the thermoplastic can 100 and the pot seal 110 , as well as facilitating disassembly and maintenance.

[0049] According to the pressure gas storage tank of the present invention, the tank volume can be flexibly customized by cutting thermoplastic tubes of different lengths to form thermoplastic tank barrels 100, and the thermoplastic tubes can be continuously extruded, which improves production efficiency compared to the traditional method of individually injection molding each thermoplastic tank barrel 100.

[0050] In addition, according to the pressure gas storage tank of the present invention, as the gas pressure in the bottle increases (within a certain range), the thermoplastic tank barrel 100 and the tank seal 110 (especially the outer ring 113) are more tightly connected, thereby achieving better sealing.
