Description

Technical Field

[0001] This utility model belongs to the field of oxygen cylinders and relates to oxygen cylinders. Background Technology

[0002] Oxygen cylinders are high-pressure containers used to store oxygen. They are generally made of alloy structural steel through hot stamping and pressing, and can be divided into industrial oxygen cylinders and medical oxygen cylinders according to their uses. Currently, whether industrial or medical, most oxygen cylinders are hollow cylindrical structures, typically between 1m and 1.65m in height, filled with high-pressure oxygen, and used vertically (in special cases, cryogenic Dewar flasks are used horizontally, but these store liquid oxygen and have a different structure and purpose than traditional oxygen cylinders). The main reason for vertical use is that oxygen is denser than air, and upright operation allows the gas inside the cylinder to be evenly distributed through the valve. If placed horizontally or upside down, gravity may cause residual water or impurities to accumulate near the valve, affecting gas purity. In addition, there are manufacturing difficulties; a straight cylindrical structure is easier to process.

[0003] In practice, due to the elongated, upright structure of oxygen cylinders, no matter how rigorous the manufacturing process or how careful the handling, the risk of explosion due to tipping or mechanical impact remains significant. Although oxygen cylinders usually have protective sleeves, the cumbersome installation does not mitigate the potential risks of the elongated structure (a significant tipping risk still exists at a height of 1m-1.65m). Even with protective measures, the valve can still experience considerable vibration during a tipping impact, potentially loosening and triggering a series of safety incidents. Specifically, when the valve becomes dislodged, the cylinder can move at high speed in the opposite direction under high-pressure gas. The small bottom area of ​​the cylinder results in high impact pressure, easily leading to a major safety accident.

[0004] This application is submitted to address the aforementioned issues. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing an oxygen cylinder. This oxygen cylinder reduces safety hazards by changing the overall shape and structure, and solves the problem that the existing oxygen cylinders have significant safety hazards due to their upright structure.

[0006] The objective of this utility model can be achieved through the following technical solution: an oxygen cylinder, comprising a cylinder and a main valve, wherein the main valve has an oxygen outlet and a connecting part, characterized in that the cylinder comprises a main cylinder body arranged horizontally and a secondary cylinder body located above the main cylinder body, the length of the main cylinder body is greater than that of the secondary cylinder body, the main cylinder body and the secondary cylinder body are integrally connected, the bottom of the secondary cylinder body is connected to the main cylinder body, the top of the secondary cylinder body forms a bottle mouth, the interface of the connecting part is threadedly connected to the bottle mouth, and further comprising a fixing member, the fixing member restricting the circumferential rotation of the main cylinder body.

[0007] The main valve is an essential component of an oxygen cylinder. The oxygen outlet is used to output oxygen, and the connector is used to connect to the cylinder. The specific structure and principle are not detailed here, as they are existing technology. In addition, the valve system of an oxygen cylinder also includes a pressure regulating valve, an explosion-proof valve, and a safety valve, which are not relevant to the innovation of this case and will not be described further. This oxygen cylinder still adopts a one-piece structure. During the manufacturing process, the cylinder body is bent to form the main body and the auxiliary body. The one-piece structure ensures strength. The length of the horizontally lying main body determines the final height of this oxygen cylinder. Therefore, the design of the main body being longer than the auxiliary body effectively shortens the overall height of the cylinder. This significant reduction in overall cylinder height greatly reduces the safety hazard of tipping. At the same time, the horizontally lying main body has a large contact area with the ground when placed, thus providing strong stability with the help of fixing components. The function of the fixing components is to prevent the cylinder from rolling and to achieve fixation. The secondary bottle is positioned upwards, meaning the bottle opening and main valve are located at the top. This avoids the problem mentioned in the background technology of impurities or moisture depositing at the valve, causing gas impurity. The above design achieves both horizontal positioning of the bottle and ensures gas purity.

[0008] In the aforementioned oxygen cylinder, the vertical distance between the cylinder opening and the bottom of the cylinder does not exceed 40% of the sum of the lengths of the main cylinder and the auxiliary cylinder.

[0009] In practice, the vertical distance between the bottle opening and the bottom of the gas cylinder is only about one-third, significantly reducing the overall height.

[0010] In the oxygen cylinder described above, an O-ring is provided between the connecting part and the cylinder opening.

[0011] An O-ring is installed at the connection to enhance the seal.

[0012] In the oxygen cylinder described above, the connecting part is axially elongated to form a long axis structure.

[0013] In this design, the length of the connecting part is increased to increase the overall length of the main valve. This is to appropriately increase the operating height and avoid the main valve being too low and inconvenient to use.

[0014] In the aforementioned oxygen cylinder, the main cylinder body and the auxiliary cylinder body are set at an obtuse angle.

[0015] The obtuse angle design prevents excessive bending during cylinder manufacturing, which could lead to stress concentration and ensure the overall strength of the cylinder. Furthermore, the obtuse angle design ensures that the axis of the cylinder opening and the cylinder's axis are not aligned. Therefore, even if an accident occurs causing the cylinder to move in the opposite direction under high-pressure gas, the impact surface is likely to be the larger cylinder body rather than the end face of the cylinder, thus potentially significantly reducing the damage.

[0016] In the aforementioned oxygen cylinder, the obtuse angle formed by the main cylinder body and the auxiliary cylinder body is greater than 100 degrees.

[0017] The purpose of the obtuse angle structure between the main cylinder and the auxiliary cylinder is to position the main valve above the cylinder. Therefore, in order to consider the overall processing difficulty of the cylinder and the overall strength and stress uniformity after processing, the angle between the main cylinder and the auxiliary cylinder should not be too small.

[0018] In the aforementioned oxygen cylinder, the fixing component is a box-shaped structure with a circular cavity at one end. One end of the main cylinder is inserted into the circular cavity and fixed. The bottom surface of the fixing component is an inclined placement plane.

[0019] The main cylinder is inserted into the circular cavity and welded in place. The bottom of the main cylinder has a placement point on the end opposite to the placement plane. Due to the presence of the fixing parts, a height difference is created between the bottom of one end of the gas cylinder and the bottom of the other end. Therefore, the placement plane is set to be inclined so that both the placement point and the placement plane can be placed stably.

[0020] In the aforementioned oxygen cylinder, the fixing component is made of steel.

[0021] Compared with existing technologies, this oxygen cylinder has the following advantages:

[0022] 1. The main and auxiliary structure design of this oxygen cylinder significantly reduces the overall height of the cylinder, greatly reducing the safety hazard of tipping over. At the same time, the horizontal main cylinder has a large contact area with the ground when placed, resulting in strong stability.

[0023] 2. The mouth and main valve of this oxygen cylinder are located at the top, which avoids the problem of impurities or moisture depositing at the valve, as mentioned in the background art, causing impurities in the gas. The above design achieves both horizontal cylinder position and gas purity.

[0024] 3. The obtuse angle design of the main and auxiliary cylinders in this oxygen cylinder ensures that the axis of the cylinder opening is not aligned with the axis of the cylinder, which can significantly reduce the potential for injury. Attached Figure Description

[0042] like Figures 1 to 3 As shown, this oxygen cylinder includes a cylinder 1 and a main valve 2. The main valve 2 has an oxygen outlet 2a and a connecting part 2b. The cylinder 1 includes a horizontally arranged main cylinder body 1a and a secondary cylinder body 1b located above the main cylinder body 1a. The length of the main cylinder body 1a is greater than that of the secondary cylinder body 1b. The main cylinder body 1a and the secondary cylinder body 1b are integrally connected. The bottom of the secondary cylinder body 1b is connected to the main cylinder body 1a, and the top of the secondary cylinder body 1b forms a bottle mouth 1b1. The interface 2b1 of the connecting part 2b is threadedly connected to the bottle mouth 1b1. It also includes a fixing member 3, which restricts the circumferential rotation of the main cylinder body 1a. The main valve 2 is an essential component of the oxygen cylinder. The oxygen outlet 2a is used to output oxygen, and the connecting part 2b is used to connect to the cylinder 1. The specific structure and principle are not described in detail, as they are existing technologies. In addition, the valve system of the oxygen cylinder also includes a pressure regulating valve, an explosion-proof valve, and a safety valve, etc., which are not relevant to the innovation of this case and will not be described in detail. The oxygen cylinder 1 still adopts a one-piece structure. During the manufacturing process, the cylinder body is bent to form the main cylinder 1a and the auxiliary cylinder 1b. The one-piece structure ensures strength. The length of the horizontally lying main cylinder 1a determines the final height of the oxygen cylinder. Therefore, the design that the length of the main cylinder 1a is greater than that of the auxiliary cylinder 1b effectively shortens the overall height of the cylinder 1. The significant reduction in the overall height of the cylinder 1 greatly reduces the safety hazard of tipping. At the same time, the horizontally lying main cylinder 1a has a large contact area with the ground when placed, so it has strong stability with the cooperation of the fixing component 3. The function of the fixing component 3 is to prevent the cylinder 1 from rolling and to achieve fixation. The auxiliary cylinder 1b is set upward, that is, the cylinder mouth 1b1 and the main valve 2 are located at the top. This avoids the problem mentioned in the background technology of impurities or moisture depositing at the valve, causing gas impurity. Through the above design, both the horizontal lying of the cylinder body and the purity of the gas are achieved.

[0043] The vertical distance from the bottle opening 1b1 to the bottom of the gas cylinder 1 is one-third of the sum of the lengths of the main cylinder body 1a and the auxiliary cylinder body 1b, significantly reducing the overall height. An O-ring 4 is provided between the connecting part 2b and the bottle opening 1b1. The O-ring 4 at the connection enhances the seal. The connecting part 2b is axially elongated to form a long-axis structure. In this design, the elongation of the connecting part 2b increases the overall length of the main valve 2, which is to appropriately increase the usable height and avoid the main valve 2 being too low and inconvenient to use. The main cylinder body 1a and the auxiliary cylinder body 1b are set at an obtuse angle of 120 degrees. The obtuse angle setting avoids excessive bending during the processing of the gas cylinder 1, leading to stress concentration and ensuring the overall strength of the gas cylinder 1. Furthermore, the obtuse angle setting ensures that the axis of the bottle opening 1b1 and the axis of the gas cylinder 1 are not on the same line. Therefore, even if an accident occurs causing the gas cylinder 1 to move in the opposite direction under high-pressure gas, the impact surface with the object is likely not the end face of the gas cylinder 1, but rather the larger surface area of ​​the cylinder body, thus potentially reducing the damage. The obtuse angle between the main cylinder body 1a and the auxiliary cylinder body 1b is designed to position the main valve 2 above the gas cylinder 1. Therefore, considering the overall processing difficulty, strength, and stress uniformity of the gas cylinder 1 after processing, the angle between the main cylinder body 1a and the auxiliary cylinder body 1b should not be too small. The fixing component 3 is a box-shaped structure made of steel. One end of the fixing component 3 has a circular cavity 3a. One end of the main cylinder body 1a is inserted into the circular cavity 3a and fixed. The bottom surface of the fixing component 3 is an inclined placement plane 3b. The main cylinder body 1a is inserted into the circular cavity 3a and welded in place. The bottom of the main cylinder body 1a, opposite to the placement plane 3b, has a placement point 1a1. Due to the presence of the fixing component 3, a height difference is created between the bottom of one end of the gas cylinder 1 and the bottom of the other end. Therefore, the placement plane 3b is set to be inclined so that both the placement point 1a1 and the placement plane 3b can be stably placed on the ground.
