Description

Technical Field

[0001] This utility model relates to the field of gas cylinders, and in particular to a high-pressure gas storage cylinder structure. Background Technology

[0002] Steel cylinders are steel cylinders used to store high-pressure oxygen, coal gas, liquefied petroleum gas, etc. The safe storage and transportation of gases in steel cylinders is crucial. Steel cylinders generally contain permanent gases, liquefied gases, or mixtures of gases. Because the solvent capacity of a steel cylinder is limited, and to ensure the gas can flow normally from the valve, the gas pressure inside the cylinder is much higher than the external pressure; therefore, the pressure-bearing capacity of the cylinder is extremely important. Improving the pressure-bearing capacity of steel cylinders is a current research and development focus. Utility Model Content

[0003] The purpose of this invention is to provide a high-pressure gas cylinder structure that can improve the pressure resistance of the cylinder and make it less prone to damage.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A high-pressure gas storage cylinder structure includes an outer shell and a cylinder body. The cylinder body is located inside the outer shell and is fixedly connected to the outer shell. A reinforcing structure is provided between the cylinder body and the outer shell to increase the robustness of the cylinder body and the outer shell. Two sealing plates are also provided between the cylinder body and the outer shell. One side of the two sealing plates is fixedly connected to the outer wall of the cylinder body, and the other side of the two sealing plates is fixedly connected to the inner wall of the outer shell. The space between the two sealing plates is a safety cavity. A safety valve is provided on the cylinder body. The inner cavity of the cylinder body communicates with the safety cavity through the safety valve. An exhaust valve is fixedly provided on the cylinder body. The outer shell is fixedly connected to the side wall of the exhaust valve. The exhaust valve has a side exhaust hole. The safety cavity communicates with the valve cavity of the exhaust valve through the side exhaust hole.

[0006] Preferably, the reinforcing structure includes an inner reinforcing rib and an outer reinforcing rib. The inner reinforcing rib is disposed on the inner wall of the outer shell and is fixedly connected to the inner wall of the outer shell. The outer reinforcing rib is disposed on the outer wall of the bottle and is fixedly connected to the outer wall of the bottle.

[0007] Preferably, both the inner and outer reinforcing ribs include transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs are arc-shaped and are arranged around the outer wall of the bottle or the inner wall of the outer shell. The longitudinal reinforcing ribs are connected to several transverse reinforcing ribs.

[0008] Preferably, the reinforcement structure further includes several support rods, with inner and outer reinforcing ribs connected to both ends of the support rods respectively.

[0009] Preferably, the vent valve includes a valve body and a valve core, the valve core being located in the valve cavity within the valve body, the valve body having a nozzle communicating with the valve cavity, and the lower end of the valve body also having a bottom vent hole communicating with the valve cavity.

[0010] The beneficial effects of this utility model are as follows: through the double-layer design, the outer shell can support the bottle body, enabling the bottle body to withstand greater pressure; and a safety chamber is provided, so that when the pressure inside the bottle is too high, the gas inside will enter the safety chamber, thereby indirectly improving the pressure-bearing capacity of the bottle body.

[0015] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0016] like Figures 1 to 3 As shown, a high-pressure gas storage cylinder structure includes an outer shell 1 and a cylinder 2. The cylinder 2 is located inside the outer shell 1, and the bottom of the cylinder 2 is fixedly connected to the bottom of the outer shell 1, thereby fixing the relative position between the cylinder 2 and the outer shell 1.

[0017] A reinforcing structure is provided between the bottle body 2 and the outer shell 1. The reinforcing structure includes an inner reinforcing rib 7, an outer reinforcing rib 8, and several support rods 11 for connecting the inner reinforcing rib 7 and the outer reinforcing rib 8. The inner reinforcing rib 7 is fixed to the inner wall of the outer shell 1, and the outer reinforcing rib 8 is fixed to the outer wall of the bottle body 2.

[0018] Both the inner reinforcing rib 7 and the outer reinforcing rib 8 include transverse reinforcing ribs 9 and longitudinal reinforcing ribs 10. Several transverse reinforcing ribs 9 on the same component are evenly distributed in height. In this design, the transverse reinforcing ribs 9 are arc-shaped and adhere to the outer wall of the bottle body 2 or the inner wall of the outer shell 1. The longitudinal reinforcing ribs 10 are vertically arranged and also longitudinally adhere to the outer wall of the bottle body 2 or the inner wall of the outer shell 1. The transverse reinforcing ribs 9 and the longitudinal reinforcing ribs 10 can prevent deformation of the bottle body 2 and the outer shell 1, increasing their pressure-bearing capacity.

[0019] Two sealing plates 3 are also provided between the bottle body 2 and the outer shell 1. One side of the two sealing plates 3 is fixedly connected to the outer wall of the bottle body 2, and the other side of the two sealing plates 3 is fixedly connected to the inner wall of the outer shell 1. The space between the two sealing plates 3, the outer wall of the bottle body 2, and the inner wall of the outer shell 1 is a safety cavity 4, which has no reinforcing ribs. A safety valve 5 is provided on the bottle body 2, and the inner cavity of the bottle body 2 communicates with the safety cavity 4 through the safety valve 5. When the air pressure inside the bottle body 2 exceeds a certain value, the air pressure inside the bottle body 2 will automatically push open the valve of the safety valve 5, allowing the gas inside the bottle to flow into the safety cavity 4, slowing down the flow of gas inside the bottle body 2, thereby indirectly improving the pressure resistance of the bottle body 2.

[0020] A vent valve 6 is fixedly mounted on the bottle body 2. The outer shell 1 is fixedly connected to the side wall of the vent valve 6. The vent valve 6 includes a valve body 62 and a valve core 63. The valve core 63 is located in the valve cavity inside the valve body 62. A nozzle 64 is provided on the valve body 62, and the nozzle 64 communicates with the valve cavity. When the vent valve 6 is opened, the gas inside the bottle body 2 can enter the valve cavity through the bottom vent hole 65 at the lower end of the valve body 62 and be ejected from the nozzle 64.

[0021] The vent valve 6 is equipped with a side vent hole 61, and the safety chamber 4 is connected to the valve chamber of the vent valve 6 through the side vent hole 61. When the vent valve 6 is opened, the gas in the safety chamber 4 can also enter the valve chamber and be discharged through the nozzle 64, without causing waste. To prevent gas from being injected directly into the safety chamber 4 from the valve chamber, a one-way valve can be installed in the side vent hole 61 to prevent gas from entering the safety chamber 4 from the valve chamber.

[0022] The safety chamber 4 has a small volume, so when the bottle 2 is filled with gas, the pressure inside the bottle 2 will not reach a level that would allow the safety valve 5 to open. The safety chamber 4 serves as a safety structure to prevent the bottle 2 from exploding when the pressure inside the bottle 2 increases due to external environmental factors, such as high temperatures, during storage after filling.

[0023] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
