Technical Field
[0001] The utility model is applied to the technical field of sealed chambers, and particularly relates to an ultra-high pressure sealed chamber. Background Art
[0002] With the continuous advancement of science and technology, the production and assembly processes of various products are becoming more and more intelligent and automated. For example, the production processes of bottled water, packaged food and other products can be automated. However, after the product packaging is completed, the packaged products need to be subjected to various tests such as appearance and airtightness, as well as high-pressure sterilization. During the testing or ultra-high-pressure sterilization process, the products need to be pressurized by sealing and pressurizing equipment to meet the factory requirements. Currently, the sealed warehouses on the market are mainly sealed by combining a single-layer rubber ring on the warehouse cover with the warehouse body and a locking mechanism. This method is cumbersome to operate and requires manual intervention to lock or unlock. In addition, the single-layer sealing rubber ring is prone to deformation in an ultra-high-pressure environment, resulting in pressure release, which greatly reduces its service life and does not meet the needs of enterprises for efficient production. If an ultra-high-pressure sealed warehouse with a simple structure, good sealing performance, and the ability to adaptively adjust the sealing strength can be designed, the above problems can be solved.

As the internal pressure of the silo body continues to increase, the water pressure will push the open end of the U-shaped sealing ring to expand outward and press the inside of the sealing cavity and the Z-shaped metal ring. At the same time, the water pressure will push the expansion sealing ring to expand outward, so that the Z-shaped metal ring and the U-shaped sealing ring can be tightly attached to the inside of the sealing cavity. At the same time, the expansion sealing ring can prevent water from flowing out of the gap between the Z-shaped metal ring and the stepped groove. The greater the pressure, the stronger the sealing.

[0022] like Figures 1 to 9 As shown, in this embodiment, the utility model includes a bin body 1 and a bin cover 2, a sealed cavity 3 is provided in the middle of the bin body 1, the bin cover 2 includes a bin cover body 4, a lid 5 and a sealing assembly 6, the sealed end of the bin cover body 4 cooperates with the open end of the sealed cavity 3, the lid 5 is arranged at the bottom of the sealed end of the bin cover body 4, a stepped groove 7 is provided in the middle of the sealed end of the bin cover body 4, the sealing assembly 6 is arranged on the stepped groove 7, the sealing assembly 6 includes a Z-shaped metal ring 61, a U-shaped sealing ring 62, a supporting ring 63 and an expansion sealing ring 64, a sealed water channel 8 is provided between the lid 5 and the sealed cavity 3, the lid 5 is provided with several water inlet holes 9 and sealed water through holes 10, the sealed water channel 8 and the sealed water through holes 10 are respectively matched with the U-shaped sealing ring 62 and the expansion sealing ring 64, a water injection channel 11 is provided in the middle of the bin cover body 4, and several of the water inlet holes 9 are connected to the external supercharger through the water injection channel 11. It can be seen that the middle part of the bin cover body 4 is connected with the inner side of the sealing cavity 3 to complete the initial sealing. The plurality of water inlet holes 9 can make the water flow more stable. When the water pressure in the sealing cavity 3 increases, the expansion sealing ring 64 expands and pushes the Z-shaped metal ring 61 to close to the sealing cavity 3 through the supporting ring 63. At the same time, the open end of the U-shaped sealing ring 62 is adaptively deformed and expanded outward, clamping the sealing cavity 3 to achieve secondary sealing. The sealing effect can be adaptively adjusted according to the pressure, and can be applied to ultra-high pressure environments, with better adaptive sealing effect.
[0023] like Figure 3 、 Figure 5 as well as Figure 8As shown, in this embodiment, the Z-shaped metal ring 61 is connected to the stepped groove 7, the expansion seal 64 is disposed at the end of the Z-shaped metal ring 61 away from the lid 5 and engages with the stepped groove 7, and the support ring 63 is disposed between the end of the Z-shaped metal ring 61 away from the lid 5 and the expansion seal 64. Thus, after the Z-shaped metal ring 61 is installed in the stepped groove 7, it engages with the bin cover body 4 and the inner limit of the sealing cavity 3 to achieve a preliminary seal.
[0024] like Figure 3 and Figure 6 As shown, in this embodiment, the U-shaped sealing ring 62 is disposed on the end of the Z-shaped metal ring 61 close to the cover 5 and cooperates with the inner wall of the sealing cavity 3. As can be seen, the U-shaped sealing ring 62 can prevent water from flowing out from between the Z-shaped metal ring 61 and the inner wall of the sealing cavity 3 and causing pressure relief.
[0025] like Figure 6 and Figure 8 As shown, in this embodiment, the end of the Z-shaped metal ring 61 that contacts the stepped groove 7 is provided with a high-pressure water guiding slope 12. High-pressure water enters the gap between the Z-shaped metal ring 61 and the stepped groove 7 through the sealing water through-hole 10 and the high-pressure water guiding slope 12, and cooperates with the expansion seal 64. Thus, the high-pressure water guiding slope 12 allows water to flow more smoothly into the gap between the Z-shaped metal ring 61 and the stepped groove 7.
[0026] like Figure 3 and Figure 8 As shown, in this embodiment, the opening direction of the U-shaped sealing ring 62 is toward the bottom of the sealed cavity 3, and high-pressure water cooperates with the open end of the U-shaped sealing ring 62 through the sealed water channel 8. It can be seen that the opening direction of the U-shaped sealing ring 62 toward the bottom of the sealed cavity 3 allows water to more smoothly flow into the open end of the U-shaped sealing ring 62, causing deformation.
[0027] like Figure 1 and Figure 3 As shown, in this embodiment, a water inlet connection port 13 is provided at the bottom of the bin cover body 4, the water inlet connection port 13 is connected to the water injection channel 11, and the external supercharger is connected to the water inlet connection port 13. It can be seen that the bin cover body 4 is connected to the external supercharger through the water inlet connection port 13.
[0028] like Figure 9As shown, in this embodiment, the plurality of water inlet holes 9 are provided in the middle of the cover 5, and the water outlet end of the bin cover body 4 is provided with a water storage stepped groove 14, which cooperates with the plurality of water inlet holes 9. Thus, the water storage stepped groove 14 can store water flow to prevent high-speed water flow from directly rushing into the sealed cavity 3, and the plurality of water inlet holes 9 can disperse the water flow to make the flow rate more stable.
[0029] As shown in the figure, in this embodiment, the outer edge of the opening end of the sealed cavity 3 is provided with an installation guide slope 15, and the sealing end of the bin cover 2 cooperates with the installation guide slope 15. It can be seen that the installation guide slope 15 can prevent the bin cover 2 from being bumped or scratched during the docking process of the bin body 1.
[0030] The working principle of the present utility model is as follows: the product to be tested under high pressure or to be sterilized is placed in the sealed cavity 3, the sealed cavity 3 is filled with water, and then the silo cover body 4 is connected to the sealed cavity 3 to realize the preliminary sealing of the silo body 1, and the external booster is connected to the water inlet connection port 13, and the external booster is started. High-speed water flows into the sealed cavity 3 through the water injection channel 11, and the water pressure will push the expansion sealing ring 64 to expand outward, and through the supporting ring 63, the Z-shaped metal ring 61 can be tightly attached to the inner side of the sealed cavity 3, and at the same time, the open end of the U-shaped sealing ring 62 undergoes adaptive deformation and outward expansion, respectively clamping the inner side of the sealed cavity 3 and the Z-shaped metal ring 61, to realize the secondary adaptive sealing of the silo body 1.
[0031] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
