Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-pressure gas filling, and particularly relates to a two-stage gas pressurization control system. BACKGROUND

[0002] In industrial production and scientific research, a gas pressurization control delivery system is widely used in industries such as petroleum and natural gas, chemical industry, aerospace, food processing and the like, for increasing the pressure of gas to a required level and delivering it to downstream applications. A conventional multi-stage gas pressurization control delivery system often uses multiple independent drive units to be responsible for the pressurization task of each stage, and then is delivered to the downstream, which makes the whole system bulky and heavy, and due to the complex coordinated control between the drive units, faults are easily caused, affecting the reliability and stability of the system. In addition, in the conventional system, when the downstream pressure is consumed too quickly, the pressurizer will be frequently started to supplement the gas pressure. However, frequent start-stop not only increases the energy consumption of the system, but also can cause the mechanical parts of the pressurizer to wear out quickly, reducing its service life, and frequent start can also cause fluctuations in the system pressure, resulting in unstable gas output.

[0029] The two-stage gas pressurization control system provided by the present application has at least the following beneficial effects:

[0030] The single-driver two-stage gas pressurization device provided by the present application has the advantages of compact structure, high automation, high work efficiency and strong stability. By arranging the primary compressor and the secondary compressor on both sides of a single driver and using a two-position four-way air control valve and a pilot valve to realize automatic reversing of the driving gas, the device realizes efficient and smooth switching between primary and secondary gas compression. This not only reduces the volume and weight of the system, but also simplifies the coordinated control between components, reduces the possibility of system failure, and improves the reliability and stability of the entire system.

[0031] The dual-stage gas booster control system is particularly suitable for space-limited environments and industrial applications that require high-pressure gas. Traditional multi-stage dual-stage gas booster control systems typically use multiple independent drive units to handle each stage of boosting, resulting in a large and cumbersome system. The proposed solution significantly reduces the floor space, making equipment installation more flexible and adaptable. In addition, due to the use of an efficient reversing mechanism and tight integration design, the device reacts quickly when starting and stopping, can quickly respond to changes in downstream application requirements, ensuring continuous and stable high-pressure gas supply, meeting the needs of different application scenarios.

[0032] In terms of energy efficiency, the single-driver dual-stage gas booster device in this application performs outstandingly. Through the optimized two-stage compression design, it can increase the gas pressure to a maximum of 5 times the original pressure in the first compression stage, and further increase to 230 times in the second compression, ensuring that the output gas reaches the required high pressure level. This efficient boosting method maximizes the use of driving gas energy, avoiding unnecessary energy loss, thereby improving energy use efficiency. At the same time, the introduction of the cooling system effectively solves the problem of heat generated during compression, ensuring the long-term stable operation of the equipment, prolonging the service life, and also improving the overall work efficiency.

[0033] Safety and reliability are also important advantages of this application. To prevent safety hazards caused by system overpressure, this application integrates a complete safety mechanism, including safety branches, a fourth pressure gauge, exhaust valves, and safety valves, forming a complete safety protection mechanism. These safety measures can quickly release excessive pressure in emergency situations, protecting the safety of the system and operators. Especially for applications involving flammable and explosive gases, using pneumatic actuators instead of electrical components for control greatly reduces the risk of electrical sparks causing accidents, providing higher safety assurance. Such design not only enhances the safety of the system, but also makes it more suitable for applications in highly safety-requiring fields.

[0034] Finally, this application also has high automation control capability. Through the integrated human-computer interaction unit and processing unit, users can easily set parameters and monitor system status in real time, ensuring that the boosting process of the target gas strictly follows the preset requirements. This highly automated control system not only improves the convenience of operation, but also enhances the flexibility and adaptability of the system, allowing it to adjust the working mode according to different process requirements, providing more personalized and precise services for users. In summary, the single-driver dual-stage gas booster device provided by this application not only performs outstandingly in technical performance, but also exhibits great advantages in practical applications.

[0061] The specific embodiments of the present application will be described below in conjunction with Figure 1 and Figure 10 The technical solutions of the present application are described clearly and completely, obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0062] Figure 1 is a connection diagram of a two-stage gas supercharging control system provided by an embodiment of the present application; Figure 2 is a three-dimensional structure diagram of a two-stage gas supercharging device of a two-stage gas supercharging control system provided by an embodiment of the present application; Figure 3 is a structure diagram of a two-stage gas supercharging device of a two-stage gas supercharging control system provided by an embodiment of the present application from another angle; Figure 4 is a cross-sectional structure diagram of a two-stage gas supercharging device of a two-stage gas supercharging control system provided by an embodiment of the present application; Figure 5 is a cross-sectional structure diagram of a two-stage gas supercharging device of a two-stage gas supercharging control system provided by another embodiment of the present application.

[0063] Referring to Figures 1 to 5 , a two-stage gas supercharging control system provided by an embodiment of the present application comprises: an air inlet mechanism 1, a two-stage gas supercharging device 2 and a control mechanism.

[0064] The intake mechanism 1 includes a target gas source 11 and a driving gas source 12, which are the starting points of the system. The target gas source 11 is responsible for providing the required target gas to be compressed.

[0065] In some specific examples, the target gas source 11 can be a gas supply from a gas tank or a pipeline network, ensuring a continuous and stable gas input. For example, a nitrogen tank can provide high-purity nitrogen gas, which is suitable for applications with high requirements for gas purity.

[0066] In some specific examples, the target gas can be a non-flammable and non-explosive gas such as inert gas, such as helium, neon, argon, nitrogen, etc.

[0067] The driving gas source 12 can provide driving gas as the power source for the two-stage gas booster 2.

[0068] In some specific examples, in order to save costs, the driving gas provided by the driving gas source 12 is usually compressed air, but it can also be other stable gases. The driving gas source 12 is connected to the two-stage gas booster through a pipeline and serves as the power source for the driving boosting process. The driving gas source 12 can be a compressed air station or a dedicated air compressor, ensuring the provision of compressed air with sufficient pressure and flow.

[0069] In some embodiments, the intake mechanism 1 also integrates a first pressure regulating valve 13, a target gas treatment assembly 14, and a first pressure gauge 15 to ensure that the target gas entering the two-stage gas booster 2 has stable pressure and purity.

[0070] The first pressure regulating valve 13 is connected after the target gas source 11 and is used to adjust the pressure of the target gas to a stable level suitable for subsequent processing. The regulated gas enters the target gas treatment assembly 14, which usually includes devices such as filters and dryers to remove impurities and moisture from the gas, ensuring the purity of the gas and thus improving the working efficiency and service life of the system. Finally, the first pressure gauge 15 is arranged between the target gas treatment assembly 14 and the two-stage gas booster 2 to monitor the pressure of the pre-processed gas in real time. The operator can observe the data of the first pressure gauge to adjust the system parameters in a timely manner, ensuring the safe operation of the system and maintaining the optimal working state.

[0071] In this embodiment, the two-stage gas booster control system can ensure stable input gas pressure through the first pressure regulating valve 13, providing consistent initial conditions for the boosting process; pre-process the gas (such as filtering and drying) through the target gas treatment assembly 14 to ensure gas purity and improve system reliability; and monitor the pressure of the processed gas in real time through the first pressure gauge 15, facilitating operator monitoring and adjustment to ensure safe and efficient operation of the system.

[0072] In some embodiments, the gas inlet mechanism 1 further integrates the driving gas treatment assembly 16, the second pressure regulating valve 17, the second pressure gauge 18 and the first electromagnetic valve 19 to ensure that the driving gas (power gas) entering the dual-stage gas booster has stable pressure and high quality.

[0073] The driving gas treatment assembly 16 is connected to the driving gas source 12 for purifying the input power gas, removing impurities and moisture therein, and ensuring the purity of the gas. For example, the assembly can include high-efficiency filters and dryers to prevent any particles or moisture from entering the system, thereby protecting the booster and other critical components from contamination and damage. The treated clean driving gas then passes through the second pressure regulating valve 17, which adjusts the gas pressure to a level suitable for driving the dual-stage gas booster, providing consistent operating conditions for the dual-stage gas booster 2. The second pressure gauge 18 is arranged between the second pressure regulating valve 17 and the first electromagnetic valve 19 to monitor the pressure of the driving gas after pressure regulation in real time, allowing the operator to understand and adjust the operating state of the system at any time, ensuring safety and stability.

[0074] The first electromagnetic valve 19 is arranged between the second pressure regulating valve 17 and the dual-stage gas booster 2, and the first electromagnetic valve 19 is electrically connected to the control mechanism to receive control instructions from the control mechanism for quick opening and closing, control the flow of power gas, and achieve precise control of the boosting process. This design not only improves the response speed and control accuracy of the system, but also enhances the overall safety and reliability.

[0075] By introducing these components, the gas inlet mechanism 1 can maintain efficient and stable operation in complex and variable working environments. In particular, for applications requiring high precision and high reliability, such as the addition of nitrogen during the polyurethane board foaming process, this optimized design significantly improves the performance of the system, ensuring the consistency of the production process and the stability of the product quality.

[0076] Referring to Figures 2 to 5 , the dual-stage gas booster 2 includes a primary compressor 21, a secondary compressor 22 and a driver 23, wherein the primary compressor 21 and the secondary compressor 22 are respectively installed on both sides of the driver 23, ensuring a compact design and efficient workflow.

[0077] The primary compressor 21 is arranged on one side of the driver 23, and a primary compression chamber 211 is formed inside the primary compressor 21. The primary compressor 21 is provided with a primary compression inlet 2111 and a primary compression outlet 2112 that can communicate with the primary compression chamber 211. The target gas in the target gas source 11 passes through the first pressure regulating valve 13, the target gas treatment assembly 14, and the first pressure gauge, enters the primary compression chamber 211 of the two-stage gas pressurizing device from the primary compression inlet 2111, and is preliminarily compressed inside the primary compression chamber 211. The compressed gas is discharged through the primary compression outlet 2112 and directly delivered to the secondary compressor 22 through the compressed gas delivery pipeline 212 for secondary compression. This layout simplifies the gas flow path and improves the overall efficiency of the system.

[0078] The secondary compressor 22 is installed on the other side of the driver 23, opposite the primary compressor 211. It forms a secondary compression chamber 221 inside for secondary compression of the compressed gas from the primary compressor 211. The secondary compressor 22 is provided with a secondary compression inlet 2211 and a secondary compression outlet 2212 that can communicate with the secondary compression chamber 221. The compressed gas enters from the secondary compression inlet 2211, is further compressed in the secondary compression chamber 221, and is finally discharged from the secondary compression outlet 2212, completing the entire two-stage compression process. The design of the secondary compressor 22 ensures that the gas can be output at a higher pressure, suitable for application scenarios that require higher pressure gas.

[0079] The driver 23 includes a driving member 231 and a power structure 232. The driving member 231 also has a driving chamber 2311 formed inside. The power structure 232 includes a driving rod 2321, a primary compression piston 2322, a secondary compression piston 2323, and a driving piston 2324.

[0080] The driving rod 2321 sequentially penetrates the primary compression chamber 211, the driving chamber 2311, and the secondary compression chamber 221, and is fixedly connected with the primary compression piston 2322 in the primary compression chamber 211, the secondary compression piston 2323 in the secondary compression chamber 221, and the driving piston 2324 in the driving chamber 2311.

[0081] The driving piston 2324 divides the driving chamber 2311 into two independent spaces, a primary compression driving chamber 23111 and a secondary compression driving chamber 23112, ensuring that the compression processes can be carried out in order. For example, when the driving gas enters the primary compression driving chamber 23111, it can push the driving rod 2321 to make the primary compression piston 2322 compress the gas in the primary compression chamber 211; when switching to secondary compression, the driving gas enters the secondary compression driving chamber 23112, pushes the driving rod 2321 to move in the opposite direction, and makes the secondary compression piston 2323 further compress the gas in the secondary compression chamber 221, thereby realizing continuous and efficient two-stage compression.

[0082] The driving member 231 is provided with a valve assembly 2312, which can be connected with the driving gas source 12 and is in communication with the first-stage compression driving cavity 23111 and the second-stage compression driving cavity 23112 respectively. When the driving gas in the driving gas source 12 passes through the driving gas treatment assembly 16, the second pressure regulating valve 17, the second pressure gauge 18 and the first electromagnetic valve 19 and is introduced into the driving cavity 2311 through the valve assembly 2312, the driving piston 2324 moves in the driving cavity 2311 according to the airflow direction, thereby driving the driving rod 2321 and the first-stage compression piston 2322 and the second-stage compression piston 2323 connected with the driving rod 2321 to reciprocate.

[0083] The two-stage gas pressurizing device 2 realizes efficient pressurization of the gas through the combined action of the driving gas and the compressed gas. The output pressure is determined by the pressure of the driving gas and the downstream load. Specifically, the target gas first enters the first-stage compressor 21, and through the action of the power structure 232 under the driving of the driving gas, the gas pressure can be pressurized to a maximum of 5 times the original pressure. Then, the compressed gas enters the second-stage compressor 22 from the outlet of the first-stage compressor 21 and is compressed again to finally reach the set pressure. In the second-stage compressor 22, the gas pressure can be pressurized to a maximum of 230 times the original pressure to meet the demand of high-pressure applications.

[0084] The operation of the single-driver two-stage gas pressurizing device is determined by the force balance relationship at both ends of the piston (i.e., the power structure 232). When the forces of the driving gas and the compressed gas acting on the piston reach balance, the pressurizing device stops working. With the consumption of the compressed gas by the downstream system, the downstream pressure gradually decreases, and the pressurizing device can be controlled to restart through an artificial or automatic control system, thereby resuming the compression process.

[0085] The working principle of the device is based on the pressure formula:

[0086] The pressure on the acting surface = the pressure per unit area (i.e., the pressure) × the area of the acting surface.

[0087] In specific work, the lower pressure of the driving gas acts on the large-area driving piston 2324, and through the connection of the driving piston 2324 and the driving rod 2321, the force is transmitted to the first-stage compression piston 2322 and the second-stage compression piston 2323. Since the areas of the first-stage compression piston 2322 and the second-stage compression piston 2323 are small, according to the force balance relationship, they can exert a higher pressure on the compressed gas. Only when the forces at both ends of the piston reach a balanced state, the entire pressurizing device will stop working.

[0088] This working principle ensures that the device can efficiently utilize the driving gas to achieve the pressurization process, while meeting the downstream pressure demand and optimizing energy use efficiency. The dual-stage compression mode adopted by the device can further enhance the gas pressure through secondary compression after preliminary pressurization by primary compression, thereby adapting to the demand for high-pressure gas in different application scenarios while maintaining the compactness of the structure and high reliability of operation.

[0089] In some specific examples, the pressure acting surface area of the secondary compression piston 2323 is smaller than that of the primary compression piston 2322, so as to further compress the gas.

[0090] In some specific examples, the primary compression inlet 2111, the primary compression outlet 2112, the secondary compression inlet 2211, and the secondary compression outlet 2212 are all one-way valves to prevent backflow of the gas, and their opening and closing can be controlled by the controller to ensure normal gas compression.

[0091] In some embodiments, the valve assembly 2312 includes a two-position four-way air control valve 23121 and a driving gas interface 23122. The driving gas interface 23122 is in communication with an external driving gas source and is provided on the two-position four-way air control valve 23121. The two-position four-way air control valve 23121 is in communication with the primary compression driving chamber 23111 for receiving external driving gas and delivering it to the primary compression driving chamber 23111 to drive the primary compression.

[0092] In some embodiments, the structure of the valve assembly 2312 includes a two-position four-way air control valve 23121 and a driving gas interface 23122 for efficient transmission and control of driving gas. The driving gas interface 23122 can be directly connected to a driving gas source 12, such as a compressed air system or a high-pressure gas tank, to provide stable driving gas supply. The driving gas interface 23122 is provided on the two-position four-way air control valve 23121, thereby achieving a compact design and simplifying the pipeline connection.

[0093] The two-position four-way air control valve 23121 is connected to the primary compression driving chamber 23111 through its built-in air path switching mechanism, for receiving driving gas delivered by the external gas source and directing it to the primary compression driving chamber 23111. After the driving gas enters the primary compression driving chamber, it pushes the driving piston 2324 to move in a specific direction (e.g., from left to right in the figure), thereby driving the driving rod 2321 and the primary compression piston 2322 to complete the primary compression action. Figure 4

[0094] ​During operation, the switching state of the two-position four-way pneumatic control valve 23121 can be automatically adjusted through external control signals. For example, after the primary compression driving cavity 23111 completes the movement of the driving piston 2324, the two-position four-way pneumatic control valve 23121 can switch the gas path to discharge the driving gas to the exhaust pipeline or transfer it to other cavities (such as the secondary compression driving cavity), thereby realizing a continuous compression process.

[0095] In addition, the two-position four-way pneumatic control valve 23121 effectively reduces the complexity of the internal gas path of the system, reduces the pressure loss in the gas transmission process, and improves the overall operation efficiency; the two-position four-way pneumatic control valve 23121 not only facilitates connection with various types of external gas sources, but also improves the sealing and safety of the system by reducing the number of pneumatic interfaces. The two-position four-way pneumatic control valve 23121 not only realizes precise control of the driving gas, but also has the advantages of compact structure, easy installation and maintenance, and is suitable for various industrial application scenarios.

[0096] In some embodiments, the secondary compression driving cavity 23112 is provided with a first driving reversing control member 2313 on the inner wall near the side of the primary compression cavity 211, which is used to realize linkage control between primary compression and secondary compression. The first driving reversing control member 313 is connected with the two-position four-way pneumatic control valve 3121 to realize the delivery and switching of the driving gas.

[0097] In a specific example, the first driving reversing control member 2313 can specifically adopt a first pilot valve, which includes a first valve core 23131, a first valve body 23132, and a first pilot gas path 23133. The first pilot gas path 23133 passes through the first valve core 23131 and the first valve body 23132 to finally communicate with the two-position four-way pneumatic control valve 23121, which can control the reversing of the two-position four-way pneumatic control valve 23121 by delivering the first pilot gas to the two-position four-way pneumatic control valve 23121. This reversing mechanism is a conventional technology in the art, so it will not be described here.

[0098] The first valve body 23132 is fixed on the right cavity wall of the secondary compression driving cavity 23112, and the first valve core 23131 and the first valve body 23132 are matched by a spring to control the on-off of the first pilot gas path 23133. The first valve core 23131 protrudes into the secondary compression driving cavity 23112, and during the primary compression process, the driving piston 2324 moves to the left, and the first valve core 23131 is in the first position, and the first pilot gas path 23133 is closed. Figure 5When the first drive reversing control member 2313 moves to the right, it can touch the first valve core 23131, causing the first valve core 23131 to move to the right relative to the fixed first valve body 23132, compressing the spring, so that the first pilot gas path 23133 is connected, and the first pilot gas can be delivered to the two-position four-way air control valve 23121, thereby controlling the reversing of the drive gas, i.e., starting to deliver drive gas to the secondary compression drive cavity 23112, thereby starting the secondary compression stage, causing the drive piston 2324 to move to the left, releasing the restriction on the first valve core 23131, and under the action of the spring, the first valve core 23131 is disengaged from the first valve body 23132, the first pilot gas path 23133 is disconnected, the control of the two-position four-way air control valve 23121 is ended, and the original position is restored to wait for the next control.

[0099] The introduction of the first drive reversing control member 2313 fully automates the switching process between primary compression and secondary compression, eliminating the need for additional electronic control devices and simplifying the complexity of the control system. Moreover, the triggering condition of the first drive reversing control member 313 is achieved through mechanical contact of the drive piston 2324, which effectively improves the reliability of the system and reduces possible failure points.

[0100] In some embodiments, the two-position four-way air control valve 23121 communicates with the secondary compression drive cavity 23112 through the drive gas delivery pipeline 2314, for delivering drive gas to the secondary compression drive cavity 23112 to make the drive piston 2324 perform secondary compression.

[0101] In some embodiments, the first drive reversing control member 2313 is arranged on the inner wall of the primary compression drive cavity 23111 close to the side of the secondary compression cavity 221, for realizing the cycle compression process after the completion of secondary compression. The second drive reversing control member 2315 is connected with the two-position four-way air control valve 23121 to realize the delivery and switching of drive gas.

[0102] In one specific example, the second drive reversing control member 2315 can specifically adopt a second pilot valve, including a second valve core 23151, a second valve body 23152, and a second pilot gas path 23153. The second pilot gas path 23153 passes through the second valve core 23151 and the second valve body 23152 to ultimately communicate with the two-position four-way air control valve 23121, and can control the reversing of the two-position four-way air control valve 23121 by delivering second pilot gas to the two-position four-way air control valve 23121.

[0103] The second valve body 23152 is fixed on the left side wall of the primary compression drive chamber 23112. The second valve core 23151 and the second valve body 23152 are connected by a spring to control the opening and closing of the second pilot air passage 23153. The second valve core 23151 protrudes into the primary compression drive chamber 23111. During the secondary compression process, the drive piston 2324 moves towards... Figure 5 The spring moves to the left, thus touching the second valve core 23151. This causes the second valve core 23151, which is relatively fixed to the second valve body 23152, to move to the left, compressing the spring and opening the second pilot air passage 23153. This allows the second pilot air to be supplied to the two-position four-way pneumatic control valve 23121, controlling the reversal of the driving gas. That is, the driving gas is started to be supplied to the first-stage compression drive chamber 23111, thus starting the first-stage compression stage of the second compression cycle. This causes the drive piston 2324 to move to the right, releasing the restriction on the second valve core 23151. Under the action of the spring, the second valve core 23151 and the second valve body 23152 are disengaged, the second pilot air passage 23153 is disconnected, ending its control over the two-position four-way pneumatic control valve 23121, and returning to the original position to wait for the next control.

[0104] In some embodiments, the two-stage gas booster also includes a cooler 24, which is designed to effectively manage the heat generated during compression, thereby ensuring stable operation of the device and extending its service life. The cooler 24 includes a first cooling chamber 241, a second cooling chamber 242, a cooling fluid delivery conduit 243, and a cooling conduit 244.

[0105] The first cooling chamber 241 and the second cooling chamber 242 are respectively located outside the primary compression chamber 211 and the secondary compression chamber 221 to absorb the heat generated during the compression process. The primary compression chamber 211 and the secondary compression chamber 221 generate a large amount of heat during gas compression. If this heat cannot be dissipated in time, it will affect the efficiency of the equipment and may even cause overheating. Therefore, the coolers 242 are designed to ensure smooth compression while maintaining the temperature of each chamber within a reasonable range.

[0106] The two-position four-way pneumatic control valve 23121 is connected to the cooler 24 through a cooling fluid delivery pipe 243. Cooling fluid (such as coolant liquid or gas) flows into the cooler 24 from the outside and is delivered to the second cooling chamber 242 through the cooling fluid delivery pipe 243. The second cooling chamber 242 is responsible for effectively cooling the gas that has passed through the secondary compression chamber 221. When the secondary compressed gas flows through the second cooling chamber 242, the cooling fluid absorbs heat, carries it away and discharges it out of the system. In order to further enhance the cooling effect, the second cooling chamber 242 is connected to the first cooling chamber 241 through a cooling pipe 244. Through the cooling pipe 244, the cooling fluid circulates between the two cooling chambers, forming a continuous heat exchange system, ensuring that the temperature of the primary compression chamber 211 and the secondary compression chamber 221 can be balanced and controlled.

[0107] The cooler 24 effectively solves the problem of heat accumulation during compression, ensuring the stability and safety of the system. For example, the cooling fluid can be circulated by a pump or other fluid driving device, ensuring that the cooling effect will not be affected during high load operation. At the same time, the compact structure of the cooler 24 does not occupy too much space, facilitating integration with other components of the supercharging device.

[0108] In addition, the arrangement of the cooler 24 also improves the energy efficiency of the entire gas supercharging system, avoiding efficiency reduction due to overheating. By closely integrating the cooling function with other core components of the compression system, the cooler 24 not only improves the working efficiency of the device, but also prolongs the service life of each component of the device, reduces maintenance costs, and further improves the reliability and applicability of the system.

[0109] In some embodiments, the cooling pipe 244 is arranged outside the compressed gas delivery pipe 212, aiming to effectively cool the gas passing through the compressed gas delivery pipe 212. The compressed gas delivery pipe 212 is used to deliver the compressed gas processed by the primary compressor 212 to the secondary compressor 22. In this process, the temperature of the compressed gas may increase significantly, which may affect the efficiency of the entire system or even cause equipment failure if not cooled.

[0110] In order to effectively control this temperature rise, the cooling pipe 244 is arranged around the outside of the compressed gas delivery pipe 212, forming a temperature control loop. When the cooling fluid (such as cooling water or gas) flows in the cooling pipe 244, it can absorb and carry away the heat outside the compressed gas delivery pipe 212. Through this heat exchange method, the cooling fluid carries away the heat inside the compressed gas pipe 212, so that the gas in the pipe remains within a reasonable temperature range, effectively avoiding efficiency reduction or equipment damage caused by overheating.

[0111] The structure and working principle of the cooling pipe 244 enable the system to operate stably in high-pressure and high-temperature environments. The heat exchange effect between the temperature of the cooling fluid and the compressed gas depends on factors such as the material of the cooling pipe 244, the flow rate of the fluid, and the contact area between the cooling pipe and the compressed gas delivery pipe 212. To enhance the cooling effect, the cooling pipe 244 can be made of a high-thermal-conductivity material, and the heat dissipation process can be optimized by precisely controlling the flow rate of the cooling fluid.

[0112] The advantages of this embodiment not only lie in its effective cooling of compressed gas, but also in its compact structure. By sleeving the cooling pipe 244 outside the compressed gas delivery pipe 212, it avoids occupying too much space and reduces interference with other components, facilitating the overall integration and installation of the system.

[0113] In some embodiments, the first-stage compressor 21 is provided with an exhaust muffler 213 that communicates with the first cooling cavity 241 for discharging cooled gas.

[0114] Figure 6 is a connection diagram of a two-stage gas pressurization control system provided by another embodiment of the present application.

[0115] In some embodiments, referring to Figure 6 , the two-stage gas pressurization control system is further integrated with an adjustment mechanism 3 connected to the second-stage compression outlet 2212 of the two-stage gas pressurization device 2. The adjustment mechanism 3 includes a buffer 32, a third pressure regulating valve 33, and a third pressure gauge 34.

[0116] The buffer 32 is arranged between and connected to the two-stage gas pressurization device 2 and the third pressure regulating valve 33 to ensure that the system can operate more stably and efficiently.

[0117] The buffer 32 can store a certain amount of pressurized target gas in a short time, thereby reducing pressure fluctuations in the system and providing more stable gas output. For example, when the downstream demand suddenly increases, the buffer 32 can immediately release the stored gas to quickly supplement the flow, avoiding pressure drops caused by the two-stage gas pressurization device 2 failing to respond in time. In addition, the presence of the buffer 32 can also reduce the frequent starting of the two-stage gas pressurization device 2, prolonging its service life and improving the response speed and control accuracy of the entire system. In this way, the buffer 32 enhances the stability of the system. This design is particularly suitable for industrial application scenarios that require high precision and high stability, such as the addition of nitrogen during the polyurethane board foaming process, significantly improving the consistency of the production process and the reliability of product quality.

[0118] The third pressure regulating valve 33 is arranged between the buffer 32 and the third pressure gauge 34 and connected with both, aiming to accurately adjust the gas pressure according to the specific process requirements of the customer.

[0119] When the target gas flows out after being pressurized by the buffer 32, the third pressure regulating valve 33 plays a key role in fine-tuning the gas pressure according to the customer's process requirements. For example, in the polyurethane board foaming process, different users may require different nitrogen gas pressures to optimize the foaming effect; the third pressure regulating valve 33 can flexibly respond to these individualized needs, ensuring that the output gas pressure always remains within the user-specified range. This design enhances the overall adaptability and flexibility of the system, allowing the same set of equipment to meet pressure requirements under various process conditions.

[0120] The third pressure gauge 34 is used to measure the gas pressure before output.

[0121] Figure 7 is a connection diagram of a two-stage gas pressurization control system provided by another embodiment of the present application.

[0122] In some embodiments, referring to Figure 7 , the two-stage gas pressurization control system is also integrated with an output mechanism 5 connected with the adjusting mechanism 3, for accurately controlling the start and stop of the target gas output.

[0123] In some embodiments, the output mechanism 5 adopts a pneumatic actuator, and the driving gas source 12 provides power for the pneumatic actuator. A second electromagnetic valve 121 is arranged between the driving gas source 12 and the pneumatic actuator, and the second electromagnetic valve 121 is electrically connected with the control mechanism and can receive control instructions from the control mechanism to remotely control the action of the pneumatic actuator, ensuring that it can be quickly started and stopped as needed.

[0124] When the system needs to start gas output, the control mechanism sends a signal to the second electromagnetic valve 121 to open, allowing the driving gas (which can be compressed air) provided by the driving gas source 12 to drive the pneumatic actuator to act, opening the gas output path. Conversely, when gas output needs to be stopped, the control mechanism sends a closing signal, and the second electromagnetic valve 121 cuts off the compressed air supply, and the pneumatic actuator is closed, stopping the gas flow. This design not only improves the response speed and control accuracy of the system, but also reduces the dependence on electrical components, enhancing the safety and reliability of the system. Especially for applications involving flammable and explosive gases, using a pneumatic actuator can avoid the risk of electric sparks, providing higher safety assurance.

[0125] Figure 8 is a connection diagram of a two-stage gas pressurization control system provided by another embodiment of the present application.

[0126] In some embodiments, referring toFigure 8 The two-stage gas pressurization control system is also integrated with a safety mechanism 6, which is composed of a safety branch 61, a fourth pressure gauge 62, an exhaust valve 63, and a safety valve 64, forming a complete safety protection mechanism.

[0127] The safety branch 61 is connected at one end to the pipeline between the two-stage gas pressurization device 2 and the adjustment mechanism 3, and at the other end to the fourth pressure gauge 62, which monitors the gas pressure in this critical pipeline in real time. For example, the fourth pressure gauge 62 can be a high-precision digital pressure gauge, providing accurate pressure readings to help operators understand the system status in a timely manner. The exhaust valve 63 is provided on the safety branch 61 and can quickly release excessive pressure in emergency situations to prevent system overpressure. The safety valve 64 is located between the exhaust valve 63 and the fourth pressure gauge 62 as the last line of defense, which automatically opens when the pressure exceeds the set limit to quickly release pressure and protect the safety of the system and personnel. This design not only improves the safety of the system, but also enhances the ability to respond to emergencies, ensuring effective pressure control even in abnormal working conditions and avoiding potential safety incidents.

[0130] In some embodiments, the control mechanism can also be arranged on the mounting rack 7.

[0131] In this embodiment, the two-stage gas pressurization control system integrates all key components into a single mounting rack 7, achieving an integrated and compact design, simplifying the installation process, and adapting to different process layout requirements.

The processing unit is electrically connected to the two-stage pressurization device 2, the first electromagnetic valve 19, and the second electromagnetic valve 121, respectively, to control the pressurization and output of the target gas.

[0134] The human-computer interaction unit, as the interface between the user and the system, allows the operator to input setting parameters (such as desired flow, pressure, etc.) through a touch screen, buttons, or computer software, and monitor the system status in real time. It can also display alarm information, historical data records, etc., providing an intuitive operation experience.

[0135] The processing unit is responsible for receiving instructions from the human-computer interaction unit and controlling the dual-stage gas pressurization device 2 and the first electromagnetic valve 19, thereby controlling the pressurization value of the dual-stage gas pressurization device 2 and the start or stop of the pressurization device, and also controlling the output or stop of the output mechanism 5 by controlling the second electromagnetic valve 121, ensuring that the pressurization and output process of the target gas meet the preset requirements.

[0136] In some embodiments, the control mechanism can also be connected to the target gas source 11 and the driving gas source 12 to control the release and stop of the target gas and the driving gas, further enhancing the automation performance of the system.
