Description

TECHNICAL FIELD

[0001] The utility model relates to pressure vessel technical field especially relates to a pressure vessel with overpressure protection structure. BACKGROUND

[0002] Pressure vessels are specially designed to withstand the pressure generated by the internal medium and maintain their structural integrity and sealing performance. They are widely used in petroleum, chemical industry, energy, medicine, food processing and many scientific research fields for storing, transporting and processing various high-pressure gases, liquids or reaction media. The design and manufacture of pressure vessels must strictly follow the relevant standards and specifications of the state and industry to ensure that they can withstand the predetermined pressure range while maintaining long-term stability and safety. By using high-strength materials, precise structural design and advanced manufacturing processes, pressure vessels can safely operate under extreme working conditions, effectively preventing safety accidents such as leakage and explosion, thereby ensuring the smooth progress of production processes and the safety of personnel and property. In addition, pressure vessels also need to be regularly inspected and maintained to ensure that they are always in good working condition and meet the needs of various application scenarios.

[0003] Pressure protection of pressure vessels is one of the key measures to ensure their safe operation. Safety valve setting: safety valve is an important device to prevent overpressure of pressure vessels. When the pressure in the container exceeds the specified value, the safety valve will automatically open to release excess pressure and prevent the container from being damaged or exploding due to excessive pressure. The opening pressure of the safety valve is generally set to 1.05-1.10 times the maximum working pressure of the container, and needs to be regularly checked, calibrated and maintained to ensure its sensitivity and reliability. Pressure gauge monitoring: by installing a pressure gauge, the pressure change in the container can be monitored in real time. If abnormal pressure is found, the operator should immediately take measures to adjust or stop checking to prevent the pressure from continuing to rise and causing dangerous situations. The installation position of the pressure gauge should be convenient for observation, and it needs to be regularly calibrated to ensure its reading accuracy. Regular inspection and maintenance: pressure vessels must be regularly inspected, including visual inspection, pressure testing, etc. to find and timely handle possible defects and hidden dangers. At the same time, the container's accessories, instruments and meters, as well as connecting pipes, etc. also need to be maintained to ensure their normal operation.

[0013] The utility model has the following beneficial effects:

[0014] When the pressure in the pressure container body is excessive, the pressure plate can quickly respond and move to the pressure relief pipe, realizing timely pressure relief, effectively preventing container damage or explosion accidents caused by excessive pressure, and significantly improving the safety of the pressure container. The design of the hydraulic oil cylinder and the push plate allows the pressure threshold of the pressure container to be flexibly adjusted according to actual needs. By changing the extrusion force of the push plate on the pressure plate, the relative position between the pressure plate and the pressure relief pipe can be adjusted, thereby realizing precise control of the pressure relief threshold, enhancing the adaptability and flexibility of the pressure container.

[0024] Further, the top of pressure vessel body 2 is equipped with protective net 3 on the side close to all pressure relief pipes 4, and the two sides of protective net 3 are fixedly connected between the outer wall of pressure vessel body 2 and fixed plate 12, when the excess pressure is discharged by pressure relief pipe 4, protective net 3 can effectively block the possible ejected medium fragments or particulate matter, to prevent them from causing harm to the surrounding environment or operating personnel.

[0025] Further, the inner side of all pressure relief pipes 4 is equipped with one-way valve 6, when the pressure in pressure vessel body 2 exceeds the threshold and needs to be relieved, one-way valve 6 opens, and the excess pressure is discharged, and when the external pressure tries to enter pressure vessel body 2 through pressure relief pipe 4, one-way valve 6 is tightly closed, preventing the influence of external pollution or pressure fluctuation on pressure vessel body 2.

[0028] Further, the connection between the output shaft of the hydraulic cylinder 5 and the frame 1 and the connection between the output shaft of the hydraulic cylinder 5 and the pressure container body 2 are both sliding connections, this kind of sliding connection allows the output shaft of the hydraulic cylinder 5 to adjust the position flexibly when pushing the push plate 10, at the same time maintains the close fit between the frame 1 and the pressure container body 2, this design not only reduces the wear and resistance caused by friction, but also improves the working efficiency and service life of the hydraulic cylinder 5, in addition, the sliding connection also facilitates the maintenance and replacement of the hydraulic cylinder 5, reduces the later maintenance cost and workload.

[0029] In summary:

[0030] Firstly, the frame 1 serves as the supporting structure of the entire pressure vessel, and the pressure vessel body 2 is fixedly connected to the inner side of the frame 1 to provide a space for the medium to bear pressure. On the inner side of the pressure vessel body 2, the pressure plate 7 initially maintains a relatively stable position and does not trigger the pressure relief mechanism. At the same time, the pressure relief pipe 4 is connected to the top of the pressure vessel body 2 to provide a channel for the release of excess pressure. When the pressure in the pressure vessel body 2 is within the normal range, the hydraulic cylinder 5 can adjust the position of the push plate 10 as needed through the fixed connection of its output shaft and the push plate 10. This adjustment is transmitted to the pressure plate 7 through the first telescopic rod 8, which exerts a certain pre-tightening force on the pressure plate 7, thereby changing the pressure threshold of the pressure vessel body 2 to adapt to different working pressure requirements. During this process, the extrusion spring 9 is sleeved on the first telescopic rod 8 to provide additional elastic restoring force between the push plate 10 and the pressure plate 7, ensuring the smooth movement of the pressure plate 7 when the pressure changes. Once the pressure in the pressure vessel body 2 exceeds the set threshold, the excess pressure will directly act on the pressure plate 7, pushing it to move towards the pressure relief pipe 4. As the pressure plate 7 gradually approaches, the opening of the pressure relief pipe 4 is opened, and the excess pressure is immediately discharged from the pressure relief pipe 4, achieving timely and effective pressure relief and protecting the pressure vessel body 2 from overpressure damage. In this process, the protective net 3 effectively blocks the possible ejected medium fragments or particulate matter, preventing them from causing harm to the surrounding environment or operating personnel. At the same time, the one-way valve 6 is installed inside all the pressure relief pipes 4 to ensure the one-way nature of the pressure relief process. When the pressure in the pressure vessel body 2 exceeds the threshold and needs to be relieved, the one-way valve 6 opens; when external pressure tries to enter the pressure vessel body 2 through the pressure relief pipe 4, the one-way valve 6 tightly closes, preventing external pollution or pressure fluctuations from affecting the pressure vessel body 2. In addition, the second telescopic rod 11 provides stable support and guidance for the push plate 10. When the hydraulic cylinder 5 drives the push plate 10 to move, the second telescopic rod 11 ensures the smooth movement of the push plate 10 along the predetermined trajectory, avoiding the situation that the position of the pressure plate 7 is inaccurate or damaged due to the deflection or shaking of the push plate 10. Finally, the sliding connection design between the output shaft of the hydraulic cylinder 5 and the frame 1 and the pressure vessel body 2 not only reduces the wear and resistance caused by friction, but also improves the working efficiency and service life of the hydraulic cylinder 5. At the same time, this sliding connection also facilitates the maintenance and replacement of the hydraulic cylinder 5, reducing the maintenance cost and workload in the later stage.
