A gas pressure stabilization and regulation platform

Abstract

This utility model discloses a gas pressure stabilization and regulation platform, which includes a gas main pipe. Detection heads are provided at both ends of the inner circumference of the gas main pipe. One end of each detection head is electrically connected to a fuzzy PID controller. The fuzzy PID controller is protected by a protective shell, and an installation component is located on the top of the protective shell. An adjustment component is located in the middle of the outer circumference of the gas main pipe. By pressing the button, the connecting rod moves, causing the rotating plate to move downwards. A guide block moves the connecting rod along the spiral groove, causing it to rotate simultaneously, thus rotating the rotating plate to the lower part of the retaining ring. Releasing the button causes the button to move upwards through the rebound force of the first spring, causing the rotating plate to move upwards and abut against the retaining ring to lock it in place. This facilitates the disassembly, assembly, and maintenance of the fuzzy PID controller, preventing gas waste caused by a decrease in the control accuracy of the fuzzy PID controller. The fuzzy PID controller makes gas pressure regulation more precise. Furthermore, the adjustment component ensures constant pressure after the valve, effectively improving the stability and response speed of gas pressure regulation.

Description

Technical Field

[0001] This utility model relates to the field of gas pressure regulation technology, specifically a gas pressure stabilization and regulation platform. Background Technology

[0002] Whether it is conventional heat exchange combustion or regenerative combustion, stable gas pressure is the key to combustion efficiency and safety. Pressure fluctuations can lead to incomplete combustion, increase energy consumption and pollutant emissions, and unstable gas pressure may also cause combustion equipment failure, shorten equipment lifespan, increase maintenance costs and downtime. Therefore, a gas pressure stabilization and regulation platform is needed.

[0003] Traditional fuzzy PID controllers in existing technologies have fixed parameters, making it difficult to adapt to the nonlinear and time-varying characteristics of gas pressure regulation. Under complex operating conditions, they are prone to problems such as large overshoot and slow regulation. For example, when the pressure in front of the valve changes suddenly, a traditional fuzzy PID controller may take a long time to regulate the pressure to the set value, failing to meet the real-time requirements of industrial production.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the PID controller is not easy to disassemble and repair, which can easily lead to inaccurate gas pressure regulation, resulting in gas waste and affecting the real-time requirements of industrial production; secondly, the stability of gas pressure regulation during the use of the device is not high enough and the response speed is not fast enough, which needs to be improved. In view of this, we propose a gas pressure stabilization and regulation platform. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments.

[0006] 1. Technical problems to be solved:

[0007] To address the problems mentioned above, such as the inconvenience of disassembling and repairing the PID controller, which easily leads to inaccurate gas pressure regulation, gas waste, and impact on the real-time requirements of industrial production, as well as the insufficient stability and slow response speed of gas pressure regulation, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a gas pressure stabilization and regulation platform that facilitates the disassembly and assembly of the fuzzy PID controller for maintenance, makes gas pressure regulation more precise, avoids gas waste, meets the real-time requirements of industrial production, and provides higher stability and faster response speed for gas pressure regulation.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A gas pressure stabilization and regulation platform includes a gas main pipe. Detection heads are located at both ends of the inner circumference of the gas main pipe. One end of each detection head is electrically connected to a fuzzy PID controller. A protective shell surrounds the fuzzy PID controller. A mounting assembly is located on the top of the protective shell. The mounting assembly includes a cover plate. A pressing plate is slidably connected to the top of the inner circumference of the cover plate. A connecting rod is rotatably connected to the bottom of the pressing plate. A first spring is located at the bottom of the pressing plate and fitted onto the outer circumference of the connecting rod. A spiral groove is formed on the outer circumference of the connecting rod. A guide block located at the bottom of the inner circumference of the cover plate is slidably connected to the inner wall of the spiral groove. A rotating plate is located at the other end of the connecting rod. A retaining ring is located on the top of the inner circumference of the protective shell. An adjustment assembly is located in the middle of the outer circumference of the gas main pipe. The spiral groove surrounds the outer circumference of the connecting rod, facilitating the movement of the guide block to rotate the rotating plate 360° to its original position.

[0012] In a preferred embodiment of the gas pressure stabilization and regulation platform of this utility model, the regulating component includes two first reducing pipes, each with a first regulating valve at one end. Branch pipes are located at both ends of the outer circumference of the main gas pipe, and bends are located at the other ends of the branch pipes and the other ends of the bends. Second reducing pipes are located at one end of each of the two second reducing pipes, and second regulating valves are located at the other ends of the two second reducing pipes. The first and second regulating valves are electrically connected to a fuzzy PID controller. The reducing pipes facilitate the reduction of the gas flow path and the control of the regulating valves.

[0013] In a preferred embodiment of the gas pressure stabilization and regulation platform of this utility model, the diameter of the top of the cover plate is larger than the diameter of the bottom of the cover plate, and the size of the cover plate matches the size of the protective shell.

[0014] In a preferred embodiment of the gas pressure stabilization and regulation platform of this utility model, the cross-section of the rotating plate is fan-shaped, and the size and position of the rotating plate match the size and position of the retaining ring.

[0015] In a preferred embodiment of the gas pressure stabilization and regulation platform of this utility model, both branch pipes are inclined towards the second regulating valve, and the inner diameter of the second reducing pipe is smaller than the inner diameter of the first reducing pipe. The inclined branch pipes facilitate smoother gas flow and prevent backflow.

[0016] As a preferred embodiment of the gas pressure stabilization and regulation platform of this utility model, pipe supports are provided at both ends of the outer circumference of the main gas pipe and the outer circumference of the two bends, and multiple heat dissipation holes are opened at the bottom of the outer circumference of the protective shell.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of gas pressure stabilization and regulation platform moves the connecting rod by pressing the button, causing the rotating plate to move downwards. The guide block moves the connecting rod along the spiral groove and rotates it, causing the rotating plate to rotate to the lower part of the retaining ring. Releasing the button causes the button to move upwards by the rebound force of the first spring, causing the rotating plate to move upwards and abut against the retaining ring to lock it in place. This facilitates the disassembly, assembly, and maintenance of the fuzzy PID controller, avoiding gas waste caused by the decrease in the control accuracy of the fuzzy PID controller. Compared with the traditional PID controller, the fuzzy PID controller makes the gas pressure regulation more precise, which can better meet the real-time requirements of industrial production.

[0021] This gas pressure stabilization and regulation platform uses a fuzzy PID controller to calculate the optimal diameter ratio of the large and small regulating valves based on the flow range and pressure fluctuation characteristics. When handling large flow rates of gas, the first regulating valve is controlled to quickly stabilize the main pressure, while the second regulating valve is responsible for precisely regulating minute flow fluctuations to avoid overshoot and ensure constant downstream pressure, effectively improving the stability and response speed of gas pressure regulation.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a gas pressure stabilization and regulation platform, including:

[0035] Please see Figures 1-5This embodiment of a gas pressure stabilization and regulation platform includes a gas main pipe 1. Detection heads 2 are fixed at both ends of the inner circumference of the gas main pipe 1. One end of each detection head 2 is electrically connected to a fuzzy PID controller 3. A protective shell 4 is snapped onto the outside of the fuzzy PID controller 3. An installation assembly 5 is snapped onto the top of the protective shell 4. The installation assembly 5 includes a cover plate 501. A pressing plate 502 is slidably connected to the top of the inner circumference of the cover plate 501. A connecting rod 503 is rotatably connected to the bottom of the pressing plate 502. A first spring 504 is fixed to the bottom of the pressing plate 502 and sleeved on the outer circumference of the connecting rod 503. A spiral groove 505 is formed on the outer circumference of the connecting rod 503. A guide block 506 located at the bottom of the inner circumference of the cover plate 501 is slidably connected to the inner wall of the spiral groove 505. A rotating plate 507 is fixed to the other end of the connecting rod 503. The protective shell... A retaining ring 508 is fixedly installed on the top of the inner wall of the 4-circumference gas main pipe 1, and an adjusting component 6 is fixedly installed in the middle of the outer wall of the circumference gas main pipe 1. By pressing the pressing plate 502, the connecting rod 503 is moved, thereby causing the rotating plate 507 to move downward. The guide block 506 moves and rotates the connecting rod 503 along the spiral groove 505, thereby causing the rotating plate 507 to rotate to the lower part of the retaining ring 508. When the pressing plate 502 is released, the rebound force of the first spring 504 causes the pressing plate 502 to move upward, thereby causing the rotating plate 507 to move upward and abut against the retaining ring 508 to complete the locking. This facilitates the disassembly, assembly and maintenance of the fuzzy PID controller 3, and avoids the gas waste caused by the decrease in the control accuracy of the fuzzy PID controller 3. Compared with the traditional PID controller, the fuzzy PID controller 3 makes the gas pressure regulation more accurate and can meet the real-time requirements of industrial production.

[0036] It is worth noting that, in order to make the gas pressure regulation more stable, the regulating component 6 specifically includes two first reducing pipes 601. A first regulating valve 602 is fixed at one end of each of the two first reducing pipes 601. Branch pipes 603 are welded to both ends of the outer circumference of the main gas pipe 1. A bend 604 is welded to the other end of each of the two branch pipes 603. A second reducing pipe 605 is welded to the other end of each of the two bends 604. A second regulating valve 606 is fixed at one end of each of the two second reducing pipes 605. The first regulating valve 602 and the second regulating valve 606 are electrically connected to the fuzzy PID controller 3. The fuzzy PID controller 3 calculates the optimal diameter ratio of the large and small regulating valves based on the flow range and pressure fluctuation characteristics. When dealing with large flow rates of gas, the first regulating valve 602 is controlled to quickly stabilize the main pressure, while the second regulating valve 606 is responsible for precisely regulating small flow fluctuations to avoid overshoot and ensure constant downstream pressure, effectively improving the stability and response speed of gas pressure regulation.

[0037] Next, in order to prevent the cover plate 501 from shaking and falling off, specifically, the diameter of the top of the cover plate 501 is larger than the diameter of the bottom of the cover plate 501, and the size of the cover plate 501 matches the size of the protective shell 4. By making the top diameter of the cover plate 501 larger than the bottom diameter, it is easy to fit into the inner cavity of the protective shell 4, making the seal tighter and more stable.

[0038] Meanwhile, to facilitate the snap-fit ​​of the cover plate 501, specifically, the cross-section of the rotating plate 507 is fan-shaped, and the size and position of the rotating plate 507 match the size and position of the retaining ring 508. The fan-shaped rotating plate 507 facilitates rotation and snap-fit ​​with the retaining ring 508.

[0039] Furthermore, to facilitate control of the regulating valve in response to various operating conditions, specifically, both branch pipes 603 are inclined toward the second regulating valve 606. The inner diameter of the second reducing pipe 605 is smaller than the inner diameter of the first reducing pipe 601. The inclined branch pipes 603 facilitate the flow direction of the gas and avoid excessive turning angles that may affect the flow. The second reducing pipe 605, with its smaller inner diameter than the first reducing pipe 601, allows the gas flow rates through the first regulating valve 602 and the second regulating valve 606 to be different, facilitating coordinated operation and flexibly responding to various operating conditions.

[0040] It is worth noting that, in order to facilitate the support of the main gas pipe 1, specifically, pipe supports 7 are fixed at both ends of the outer circumference of the main gas pipe 1 and the outer circumference of the two bends 604. Multiple heat dissipation holes are opened at the bottom of the outer circumference of the protective shell 4. The main gas pipe 1 and the bends 604 are supported by the pipe supports 7 to transfer the load, and the heat dissipation holes facilitate airflow to dissipate heat from the fuzzy PID controller 3.

[0041] Finally, to improve stability, specifically, multiple second springs 8 are fixed on both sides of the inner circumference of the protective shell 4, and a clamping plate 9 is fixed on the other end of the second spring 8. The clamping plate 9 is moved by the rebound force of the second spring 8 to clamp the fuzzy PID controller 3, which makes the installation of the fuzzy PID controller 3 more stable.

[0042] Combination Figures 1-5 The specific usage process of the gas pressure stabilization and regulation platform of this embodiment is as follows:

[0043] 1. When this device is needed as a gas pressure stabilization and regulation platform, press the button plate 502 to make the connecting rod 503 drive the rotating plate 507 to move downward. The guide block 506 moves and rotates along the spiral groove 505, causing the rotating plate 507 to rotate to the lower part of the retaining ring 508. Release the button plate 502. The rebound force of the first spring 504 drives the button plate 502 to move upward, causing the rotating plate 507 to move upward and abut against the retaining ring 508 to complete the locking. Remove the cover plate 501 and take out the fuzzy PID controller 3 for maintenance. The fuzzy PID controller 3 monitors the pressure fluctuations before and after the valve in real time and automatically optimizes the adjustment strategy.

[0044] 2: The fuzzy PID controller 3 calculates the optimal diameter ratio of the large and small regulating valves based on the flow range and pressure fluctuation characteristics. When handling large flow of coal gas, it controls the first regulating valve 602 to quickly stabilize the main pressure. When handling large flow of coal gas, it controls the second regulating valve 606 to precisely regulate small flow fluctuations.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
