Description

Technical Field

[0001] This utility model relates to the field of gas distribution technology, and in particular to a dynamic flow distribution device for multiple gas branches. Background Technology

[0002] In the modern energy supply system, natural gas, as a clean and efficient energy source, is widely used in many fields such as industrial production, commercial operation and daily life. With the continuous expansion of natural gas usage scenarios and the increasing amount of natural gas consumption, higher requirements are placed on the stability, reliability and uniformity of flow distribution of the natural gas supply system.

[0003] A gas multi-branch dynamic flow distribution device is a professional device used in gas transmission systems to adjust and distribute gas flow in multiple branches in real time and intelligently. A three-way electric regulating valve is one type. Specifically, gas enters the inlet pipe of the three-way electric regulating valve through a pipeline, and is then distributed from two outlet pipes to other branches by the three-way electric regulating valve.

[0004] The different branch pipe lengths, diameters, and inner wall roughness of the downstream gas outlet pipes create varying fluid resistances. Even if the initial flow rate setting of the electric regulating valve is the same, the actual gas flow rate reaching each load will deviate due to these resistance differences. This deviation will further increase as the pipeline is used over time. Furthermore, long-term use of the electric regulating valve can lead to issues such as valve core wear and seal aging, causing a mismatch between the actual valve opening and the theoretical opening corresponding to the control signal. This prevents the valve from accurately distributing the flow according to the preset ratio. The combination of these two factors results in uneven gas flow distribution across the branches, which is difficult for staff or users to detect in a timely manner, thus affecting the stable operation of the entire gas system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dynamic flow distribution device for multiple gas branches. It solves the problem that differences in the length, diameter, and inner wall roughness of downstream branch pipes from different gas outlets create varying fluid resistances. Even with the same initial flow rate setting for the electric regulating valve, the actual gas flow reaching each load will deviate due to these resistance differences, and this deviation will further increase with the length of time the pipeline is in use. Furthermore, long-term use of the electric regulating valve can lead to issues such as valve core wear and seal aging, causing a mismatch between the actual valve opening and the theoretical opening corresponding to the control signal. This prevents precise flow distribution according to the preset ratio. The combination of these two factors results in uneven gas flow distribution across the branches, which is difficult for staff or users to detect in a timely manner, thus affecting the stable operation of the entire gas system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dynamic flow distribution device for multiple gas branches includes a valve body and two gas outlet pipes. Each gas outlet pipe is equipped with a pressure sensor for monitoring gas flow. The valve body is equipped with a processing mechanism for processing the pressure sensor signals. The processing mechanism includes a processing module and a display module. The processing module is located outside the valve body and is used to receive and process the pressure signals transmitted by the pressure sensor. The display module is located outside the valve body and is used to issue an alarm. The pressure sensor is electrically connected to the processing module, and the processing module is electrically connected to the display module.

[0008] Preferably, each air outlet pipe is fixedly installed with a nut on the outside, the inside of the nut is connected to the inside of the air outlet pipe, the end of the pressure sensor is threadedly connected to the inside of the nut, and the end of each pressure sensor is movably fitted with a gasket.

[0009] Preferably, the valve body is provided with an integrated plate and a display module, both of which are fixedly installed on the upper surface of the integrated plate. Two positioning blocks are fixedly installed on the outside of the valve body. The two ends of the integrated plate are respectively snapped onto the outside of the two positioning blocks. Each positioning block is provided with a limit spring on its outside. Each positioning block is provided with a deformation groove on its outside. One end of the limit spring is fixedly connected to the inside of the deformation groove, and the other end extends outward.

[0010] Preferably, the integrated board is provided with a protective cover, the protective cover has a cable port on the outside, a positioning frame is fixedly installed on the outside of the integrated board, a positioning plate is snapped into the inside of the positioning frame, and the positioning plate is fixedly installed on the outside of the protective cover.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When gas enters from the valve body and flows into the two outlet pipes, pressure sensors installed in the nuts on the outside of each outlet pipe monitor the gas pressure in each outlet pipe. Since there is a correlation between gas flow rate and pressure, the pressure sensors transmit the collected pressure signals to the processing module in real time. The processing module analyzes and processes the pressure signals. When the difference in flow rate between the two outlet pipes exceeds the preset uniformity threshold, the display module will immediately issue a bright light alarm, promptly reminding the operator to check and adjust the device. This effectively ensures the uniform distribution of gas flow under multi-load conditions and maintains the stable operation of the gas system. Attached Figure Description

[0021] This application provides a dynamic flow distribution device for multiple gas branches, effectively solving the problem that differences in the length, diameter, and inner wall roughness of downstream branch pipes of different gas outlets create varying fluid resistances. Even if the initial flow rate of the electric regulating valve is the same, the actual gas flow reaching each load will deviate due to these resistance differences, and this deviation will further increase with the length of time the pipeline is in use. Furthermore, long-term use of the electric regulating valve can lead to problems such as valve core wear and seal aging, resulting in a mismatch between the actual valve opening and the theoretical opening corresponding to the control signal. This makes it impossible to accurately distribute the flow according to the preset ratio. The combination of these two factors leads to uneven gas flow distribution in each branch, which is difficult for staff or users to detect in a timely manner, thus affecting the stable operation of the entire gas system.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application effectively solves the problem that differences in the length, diameter, and inner wall roughness of branch pipes downstream of different gas outlets create varying fluid resistances. Even if the initial flow rate of the electric regulating valve is the same, the actual gas flow rate reaching each load will deviate due to these resistance differences, and this deviation will further increase with the length of time the pipeline is in use. Furthermore, long-term use of the electric regulating valve can lead to issues such as valve core wear and seal aging, causing a mismatch between the actual valve opening and the theoretical opening corresponding to the control signal. This prevents the valve from accurately distributing the flow according to the preset ratio. The combination of these two factors results in uneven gas flow distribution across the branch pipes, which is difficult for staff or users to detect in a timely manner, thus affecting the stable operation of the entire gas system. The overall approach is as follows:

[0023] To address the problems existing in the prior art, this utility model provides a dynamic flow distribution device for multiple gas branches, including a valve body 1 and two gas outlet pipes 2. Each gas outlet pipe 2 is externally equipped with a pressure sensor 3 for monitoring gas flow. The valve body 1 is externally equipped with a processing mechanism for processing the signals from the pressure sensor 3. The processing mechanism includes a processing module 4 and a display module 5. The processing module 4 is externally located on the valve body 1 and is used to receive and process the pressure signals transmitted by the pressure sensor 3. The processing module 4 can be a microcontroller. The display module 5 is externally located on the valve body 1 and is used to issue an alarm. The display module 5 is a display screen that can emit colored light. When the difference in flow values ​​between the two gas outlet pipes 2 exceeds a preset uniformity threshold, the display module 5 will issue a bright alarm to remind the operator to check and adjust. The pressure sensor 3 is electrically connected to the processing module 4, and the processing module 4 is electrically connected to the display module 5.

[0024] Each vent pipe 2 is fixedly installed with a nut 6 on the outside. The inside of the nut 6 is connected to the inside of the vent pipe 2. The end of the pressure sensor 3 is threadedly connected to the inside of the nut 6.

[0025] Each pressure sensor 3 has a gasket 7 movably fitted to its end, which enhances the sealing of the connection between the pressure sensor 3 and the nut 6, and reduces the probability of the pressure sensor 3 becoming loose.

[0026] An integrated plate 8 is provided on the outside of the valve body 1, and the processing module 4 and the display module 5 are both fixedly installed on the upper surface of the integrated plate 8.

[0027] Two positioning blocks 9 are fixedly installed on the outside of the valve body 1. The two ends of the integrated plate 8 are respectively snapped onto the outside of the two positioning blocks 9. Each positioning block 9 is provided with a limiting spring 10 on its outside. Each positioning block 9 is provided with a deformation groove 11 on its outside. One end of the limiting spring 10 is fixedly connected to the inside of the deformation groove 11, and the other end extends outward.

[0028] The integrated board 8 is provided with a protective cover 12. The protective cover 12 has a cable port 13 on its outside for connecting external cables to the processing module 4 and the display module 5. A positioning frame 14 is fixedly installed on the outside of the integrated board 8. A positioning plate 15 is snapped into the inside of the positioning frame 14. The positioning plate 15 is L-shaped and is fixedly installed on the outside of the protective cover 12.

[0029] Example 1

[0030] When gas enters from valve body 1 and flows into the two outlet pipes 2, pressure sensor 3 installed in the nut 6 outside each outlet pipe 2 monitors the gas pressure in each outlet pipe 2. Since there is a corresponding relationship between gas flow and pressure, pressure sensor 3 transmits the collected pressure signal to processing module 4 in real time for analysis and processing. When the difference in flow rate between the two outlet pipes 2 exceeds the preset uniformity threshold, display module 5 will immediately issue a bright light alarm to promptly remind the operator to check and adjust the device, thereby effectively ensuring the uniform distribution of gas flow under multi-load conditions and maintaining the stable operation of the gas system.

[0031] Example 2

[0032] The processing module 4 and display module 5 are securely mounted on the upper surface of the integrated plate 8 using bolts and other fasteners. When installing the integrated plate 8, align both ends of the integrated plate 8 with the two positioning blocks 9 respectively, and forcefully insert it into the outside of the positioning blocks 9. During this process, the outward-extending part of the limiting spring 10 is squeezed by the integrated plate 8 and moves into the inside of the deformation groove 11. After the integrated plate 8 is fully engaged, the limiting spring 10 returns to its original position due to its own elasticity and presses tightly against the outside of the integrated plate 8, reliably limiting the integrated plate 8. Then, align the protective cover 12 with the integrated plate 8 and slowly cover the outside of the integrated plate 8. At this time, the positioning plate 15 is inserted into the inside of the positioning frame 14. The protective cover 12 can shield the processing module 4 and display module 5, preventing external dust, moisture, and accidental collisions from damaging these electronic components, providing a good protective environment for the processing module 4 and display module 5, ensuring their long-term stable signal processing and display work, and timely reminding operators to check and adjust the device, ensuring the uniform distribution of gas flow under multi-load conditions.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
