In a specific implementation, the main body of the entire container of the pressure vessel tank body 1 is used to accommodate chemical substances that require high-pressure treatment. Its design can withstand high pressure and ensure the stability of the chemical substances during the treatment process. The cover body 2 is used to close the pressure vessel tank body, ensure the sealing during the treatment process, and prevent the leakage of chemical substances. At the same time, a number of important functional components are also provided on the cover body; the sealing assembly includes a first sealing ring 6, a second sealing ring 7 and a connecting pressure ring component to ensure the sealing between the cover body and the pressure vessel tank body. The first sealing ring 6 and the second sealing ring 7 fit tightly and are fixed by the connecting pressure ring component including a connecting fixing block 8 and a connecting bolt 9, thereby forming a strong sealing barrier. The connecting fixing block 8 is adapted to the outer diameter of the first sealing ring and the second sealing ring. When placed on the outside formed when they are buckled together, they can be fixed by the connecting bolt 9 to further enhance the sealing effect.
[0015] like Figure 1 As shown, building on the above approach, an annular groove 10 is provided within the connecting and fixing block 8.

Then, conduct a sealing test to check whether the sealing performance of the pressure vessel meets the requirements. This usually includes pressure testing and leakage detection. Pressure relief mechanism operation: during normal operation of the pressure vessel, if the internal pressure exceeds the preset safety value, the pressure relief valve 17 will automatically open to release the excessive pressure through the pressure relief pipe 16. This ensures that the pressure vessel can safely operate under abnormal conditions and prevent explosions or damage. Maintenance and monitoring: regularly check and maintain the pressure vessel to ensure the normal operation of components such as the sealing assembly, rubber ring pad, and pressure relief mechanism. At the same time, monitor the operating state of the pressure vessel in real time through monitoring equipment to timely discover and handle any abnormal conditions. The above is the specific working process of the new high-sealing chemical pressure vessel. During the entire working process, it is necessary to strictly follow the operating procedures and safety requirements to ensure the safe and stable operation of the pressure vessel.
