Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing equipment technology, and in particular to a novel double-layer gas storage pressure vessel. Background Technology
[0002] Double-walled gas storage pressure vessels are efficient and safe gas storage devices. Their core design features a double-layered structure, typically consisting of an inner liner and an outer cladding. The inner liner directly contacts the high-pressure gas and is made of high-strength materials to ensure pressure resistance. The outer cladding, on the other hand, is often made of lightweight composite materials or metal to enhance protection, provide thermal insulation, or resist corrosion. The gap between the two layers can be filled with cushioning material or evacuated to improve thermal insulation performance.
[0003] Existing double-walled gas storage pressure vessels typically consist of a support frame, an outer shell, and an inner liner. The support frame provides stable support to the outer shell, enabling smooth operation. The inner liner stores the gas, while the outer shell provides protection for the inner liner. By creating a vacuum in the cavity between the inner liner and the outer shell, the insulation effect is improved, allowing the inner liner to better store the internal gas.
[0004] However, the existing equipment's support frame has a fixed structure, which cannot enable the rapid movement of the equipment according to usage needs when supporting the outer shell. When it is necessary to move the container, the support frame must be removed, the container moved to the required position, and then the support frame installed to support the container. This makes the movement of the container inconvenient, time-consuming, and labor-intensive. Therefore, a new type of double-layer gas storage pressure vessel is proposed to solve the above problems.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1-4 This utility model provides an embodiment of a novel double-layer gas storage pressure vessel, comprising an outer shell 1, which provides protection and allows for better gas storage. A support mechanism is installed at the bottom of the outer shell 1 to support the vessel, facilitating movement and saving manpower, resources, and time. A connecting mechanism is installed on the outer side of the outer shell 1 to transport gas into the interior for storage. A cavity 17 is formed inside the outer shell 1; by evacuating the cavity 17, heat insulation is provided. The outer shell 1 is equipped with... The system includes a storage component; the support mechanism comprises a moving component, a positioning component, a sliding component, and a transmission component. The moving component includes a support leg 3, which is fixedly connected to the bottom of the outer casing 1. A caster wheel 4 is fixedly connected to the bottom of the support leg 3. The support leg 3 and the caster wheel 4 provide support for the outer casing 1, enabling stable operation and facilitating its movement, thus saving manpower, resources, and time. The sliding component includes a support frame 7, which is slidably connected inside the support leg 3. A slide rail 16 is provided on the outer side of the support leg 3, allowing the support frame 7 to slide within the support leg. The internal movement of support leg 3 enables the retraction and extension of support frame 7, preventing displacement during this process. A groove 8 is provided on the outer side of support frame 7. The positioning component includes a retainer 10, which is fixedly connected to the outer side of support leg 3. A positioning block 9 is slidably connected inside retainer 10, engaging with the groove 8. A spring 11 is fitted around the outer periphery of positioning block 9. The engagement of positioning block 9 and groove 8 secures support frame 7, preventing it from falling during container movement. The spring 11 provides a reset function for positioning block 9. The mechanism allows for resetting after movement. The transmission component includes a handle 6, which is slidably connected to the outside of the support frame 7. A groove 5 is provided on the outside of the support leg 3. The handle 6 prevents the support frame 7 from shrinking when supporting the container. The groove 5 allows the handle 6 to move within the support leg 3 without displacement. Through the cooperation between the various structures of the support mechanism, the container is supported effectively, allowing for better gas storage. The interactive movement of the container makes it easier to move, thus saving manpower, resources, and time.
[0036] Reference Figure 1 , Figure 5 and Figure 6 The connecting mechanism includes a discharge component, an input component, and a fixing component. The discharge component includes a connecting pipe 12, which is fixedly connected to the outside of the outer shell 1. A control valve 13 is installed on the outside of the connecting pipe 12. The cavity 17 can be evacuated into a vacuum through the connecting pipe 12 and the control valve 13, thereby enhancing the heat insulation effect of the equipment and allowing the container to better store gas. The input component includes a connecting pipe 14, which is fixedly connected to the outside of the outer shell 1. A valve 15 is installed on the outside of the connecting pipe 14. The valve 15 and the connecting pipe 14 work together to deliver gas into the container for storage and to extract gas from the container for use. The fixing component includes a slider 19, which is slidably connected to the end of the connecting pipe 14. A limit ring 22 is fixedly connected inside the slider 19. A ball bearing 23 is slidably connected to the end of the connecting pipe 14. A positioning ring 20 is fixedly connected to the outside of the connecting pipe 14. A pressure ring is fitted around the outer periphery of the connecting pipe 14. Spring 21, driven by slider 19, moves limiting ring 22, thereby releasing the lock on ball 23, making the connection of gas supply pipe and connecting pipe more convenient. After connection, spring 21 resets slider 19 and limiting ring 22, so that limiting ring 22 and ball 23 cooperate to lock gas supply pipe, preventing gas leakage during gas supply and extraction. Positioning ring 20 prevents slider 19 from shifting when moving. Storage component includes fixing block 18, which is fixedly connected to the inside of outer shell 1. Inner liner 2 is fixedly connected to the top of fixing block 18. Connecting pipe 14 passes through outer shell 1 and is fixedly connected to the outside of inner liner 2. Fixing block 18 connects outer shell 1 and inner liner 2, giving inner liner 2 a supporting effect. Inner liner 2 stores gas. Gas can be transported to inner liner 2 for storage through connecting pipe 14, and gas in inner liner 2 can also be extracted for use.
[0037] Working Principle: During operation, when gas needs to be delivered to the inner liner 2, the slider 19 is pushed to slide along the outside of the connecting pipe 14, causing the limiting ring 22 to move. This causes the limiting ring 22 to compress the compression spring 21, resulting in deformation and allowing the gas delivery pipe to be inserted into the connecting pipe 14. Once inserted, the slider 19 is released, and the compression spring 21 pushes it back to its original position. Upon resetting, the limiting ring 22 pushes the ball bearing 23 to slide, thus fixing the gas delivery pipe. After fixing, the valve 15 is opened, allowing gas to enter the inner liner 2 through the connecting pipe 14. When gas delivery is complete, the valve 15 is closed, and the slider 19 is pushed to move, allowing the gas delivery pipe to be removed. After removal, the slider 19 can be released to reset, at which point the cavity 17 can be evacuated through the connecting pipe 12, thereby enhancing the insulation effect of the equipment. When the equipment needs to be moved, the positioning block 9 can be pulled to move it in the card holder 10 and compress the spring 11 to generate deformation. At this time, the handle 6 can be pulled to move the support frame 7 upward, so that the support frame 7 extends into the support leg 3. When the support frame 7 moves to the designated position, the positioning block 9 is released, and the spring 11 pushes the positioning block 9 to reset, so that it engages with the groove 8, thereby fixing the support frame 7. At this time, the equipment can be moved by the universal wheels 4 installed at the bottom of the support leg 3. After the movement is completed, the positioning block 9 is pulled to disengage it from the groove 8, so that the support frame 7 can extend out of the support leg 3. When the support frame 7 contacts the ground, the handle 6 is pushed into the support plate 7 to achieve the fixing effect of the support frame 7, thereby supporting the equipment.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
