[0033] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 and Figure 5When using, traditional seals are generally sealed by physical combination, and the combination of the sealing cover is achieved by adding multiple bolts and the tank body 11 on the outside, which can meet the needs of use. However, when sealing, the sealing efficiency is poor through the use of the inner sealing ring, and the sealing ring is prone to aging and leakage after long-term use. Based on this, the application provides a high-pressure sealing device, including a pressure tank 1 for loading chemical liquid and a pressure cover 2 arranged on the pressure tank 1;

[0034] The pressure tank 1 includes a tank body 11 and a connecting portion 12. The connecting portion 12 is arranged on the outside of the tank body 11 and is integrally formed with the tank body 11. The integrally formed connection ensures the reliability of the connection and improves the strength and sealing of the connection.

[0035] The pressure cover 2 and the tank body 11 are integrally formed at a connection portion 12 that is sealed and connected by fasteners;

[0036] The pressure cover 2 includes a flange 25 , and a sealing convex ring 21 is provided on one side of the flange 25 . The outer side of the sealing convex ring 21 is threadedly connected to the connecting portion 12 via threads.

[0037] The area where the pressure cover 2 is connected to the tank body 11 is sealed by fasteners (such as bolts). This design not only simplifies installation and maintenance, but also improves the reliability of the seal.

[0038] The outer side of the sealing convex ring 21 is connected to the thread of the connecting portion 12 through a thread, forming a tight sealing structure, thereby ensuring reliable sealing under high pressure conditions.

[0039] When the pressure is sufficient, the gasket 29 is located in the sealing groove 26, which can further enhance the sealing effect and ensure that no leakage occurs. The design of the outer flange 25 and the bolts not only helps to seal, but also enhances the connection strength between the pressure cover 2 and the tank body 11, thereby improving the durability and safety of the overall sealing system.

[0040] The integrally formed connection portion 12 , the fastener seal and the threaded sealing convex ring 21 effectively prevent leakage of chemical liquid under high pressure conditions, thereby improving the safety and environmental protection of the tank body 11 .

[0041] The optimized sealing system reduces the volatilization and evaporation of chemical liquids during transportation and storage, maintains the stability and concentration of the liquid, and thus saves costs and resources.

[0042] The sealing structure effectively prevents external oxygen and pollutants from entering the tank body 11, protects the quality and performance of the stored liquid, and extends the service life of the liquid.

[0043] Compared with traditional complex sealing systems, the new design simplifies maintenance, reduces leakage problems caused by aging, and reduces maintenance costs and downtime.

[0046] One side of the flange 25 is provided with one or more bolt holes 24 , which are used to be combined with fasteners (such as bolts) to connect the pressure cover 2 and the tank body 11 .

[0047] An inner ring 22 is provided on the inner side of the sealing convex ring 21 , and one or more sliding grooves 23 are provided on the inner side of the inner ring 22 in an annular array.

[0048] A sealing plate 28 is installed at the chute 23. The sealing plate 28 adapts to the changes in the nozzle of the tank body 11 by moving the position of the chute 23, ensuring the sealing range and effect of the sealing plate 28. This method allows the sealing plate 28 to be adjusted as needed, improving the flexibility and adaptability of the seal.

[0049] The combination of the bolt holes 24 on the flange 25 and the fasteners enhances the connection strength between the pressure cover 2 and the connection portion 12 of the tank body 11 , thereby improving the safety and stability of the overall structure.

[0050] The sealing plate 28 can adapt to the pipe openings of the tank body 11 of different sizes and shapes by adjusting the position of the slide groove 23, ensuring that a good sealing effect can be achieved under different conditions.

[0051] Through the sliding adjustment of the slide groove 23, the maintenance frequency caused by aging or damage of the sealing ring is reduced, and the maintenance becomes simpler and more efficient.

[0052] The combination of the inner ring 22 and the slide groove 23 makes the sealing plate 28 have better adaptability and stability, maintains a good sealing effect during long-term use, and improves the reliability of the entire sealing system.

[0053] See also Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 as well as Figure 10The inner bottom of the inner ring 22 is provided with a protrusion toward the center, and a sealing groove 26 is opened at the top of the protrusion.
