Description

Technical Field

[0001] This invention relates to heat exchanger pipeline technology for heat exchange stations, and in particular to a rapid flow diversion device for heat exchange stations. Background Technology

[0002] As the core hub of a centralized heating system, the stability and intelligence level of the control system of a heat exchange station directly determine the heating efficiency and user comfort. In actual operation, heating control typically employs a combination of constant temperature regulation (setting the secondary network supply / return water temperature) and time-segmented regulation (dynamically adjusting the temperature curve according to heat demand).

[0003] Current heat exchange stations mostly employ a multi-loop parallel piping design, using a PID control strategy to adjust the opening of the primary network's electric valves. Due to differences in flow velocity and resistance characteristics between the two sets of pipes (affected by factors such as pipe diameter, number of elbows, and valve opening), uneven pressure distribution often occurs: the high-pressure side pipes endure higher pressure for extended periods, easily leading to pipe fatigue, seal aging, and localized corrosion, thus shortening their service life. While the low-pressure side pipes have higher durability, insufficient flow may result in decreased heat exchange efficiency and even the formation of localized high-temperature zones. Pressure differences further exacerbate the hydraulic imbalance in the pipe network. This imbalance not only reduces the overall system energy efficiency but also increases the energy burden on the circulating pumps. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is: the problem of uneven distribution of flow velocity and resistance pressure in multi-loop parallel pipelines of heat exchange stations.

[0005] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a rapid flow guiding device for a heat exchange station, which includes a heat exchange unit including a first flow channel, a second flow channel disposed on one side of the first flow channel, a first branch pipe located above connecting the first flow channel and the second flow channel, and a second branch pipe located below connecting the first flow channel and the second flow channel;

[0006] The flow guiding unit is located between the first flow channel and the second flow channel, and includes multiple pressure relief plates, a movable plate slidably connected inside the pressure relief plates, a limiting block disposed at the end of the movable plate, and a pressure relief component disposed in the middle part of the movable plate.

[0007] In a preferred embodiment of the rapid flow guiding device for heat exchange stations described in this invention: the first flow channel and the second flow channel have the same structure and are arranged in reverse mirror image;

[0008] The first flow channel includes multiple main pipes, a connecting pipe disposed in the middle of the main pipes, sealing rings disposed on both axial sides of the connecting pipes, and fixing discs disposed on the upper and lower sides of the connecting pipes.

[0009] In a preferred embodiment of the rapid flow diversion device for heat exchange stations described in this invention: the connecting pipe includes a groove on one side;

[0010] The fixed plate includes a fixing groove that extends through its upper and lower end faces;

[0011] Furthermore, the fixing plate is fixedly installed on the upper and lower end faces of the connecting pipe by positioning bolts on its periphery.

[0012] In a preferred embodiment of the rapid diversion device for heat exchange stations described in this invention: the pressure relief plate is slidably engaged in the sliding groove;

[0013] The pressure relief plate includes a pressure-receiving end that is slidably disposed within the connecting pipe, and a driving end that is slidably limited within the fixed groove.

[0014] In a preferred embodiment of the rapid flow diversion device for heat exchange stations described in this invention: the moving plate includes a transmission end that slides and engages with the driving end, a meshing portion protruding from one side of the transmission end, and a reset end protruding from the other side of the meshing portion.

[0015] In a preferred embodiment of the rapid flow diversion device for heat exchange stations described in this invention: the driving end includes an inclined block disposed on its inner side, and limiting grooves formed at both ends of the driving end.

[0016] In a preferred embodiment of the rapid flow guiding device for heat exchange stations described in this invention: the transmission end includes an inclined surface disposed on one side of its end;

[0017] The inclined surface mates with the inclined block.

[0018] In a preferred embodiment of the rapid diversion device for heat exchange stations described in this invention: the pressure relief assembly includes a docking valve connected between the first branch pipe and the second branch pipe respectively, a butterfly valve disposed in the inner cavity of the docking valve, a gear disposed on the valve stem of the butterfly valve, and a coupling axially connected to the gear;

[0019] The gear meshes with the meshing part.

[0020] In a preferred embodiment of the rapid flow diversion device for heat exchange stations described in this invention: the limiting block includes a fixed end that is fixedly positioned at the center of the fixed plate, and a snap-fit ​​end that protrudes from the bottom of the fixed end.

[0021] In a preferred embodiment of the rapid flow diversion device for heat exchange stations described in this invention: the reset end is slidably limited within the snap-fit ​​end, and a spring is fixedly connected to the end of the reset end.

[0022] The beneficial effects of this invention are as follows: By directly sensing the fluid pressure at the pressure-bearing end of the pressure relief plate, the driving end moves the plate in conjunction with the wedge-shaped engagement of the inclined block and the inclined plane, converting linear motion into lateral displacement, and driving the butterfly valve of the pressure relief assembly to open and close rapidly, thus achieving dynamic pressure balance regulation. Compared with traditional manual adjustment or external control systems, the mechanical linkage design of this solution can achieve dynamic balance without additional energy, significantly improving regulation efficiency. Furthermore, the bidirectional circulation of fluid between the two channels is achieved through valve switching control of the first and second branch pipes. For example, when the pressure in the first channel is too high, the fluid flows to the second channel through the first branch pipe; conversely, the pressure decreases, avoiding overload on one side of the pipeline.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of the invention.

[0032] Reference Figures 1-6 This embodiment provides a rapid flow diversion device for a heat exchange station, including a heat exchange unit 1 including a first flow channel 11, a second flow channel 12 disposed on one side of the first flow channel 11, a first branch pipe 13 located above and connecting the first flow channel 11 and the second flow channel 12, and a second branch pipe 14 located below and connecting the first flow channel 11 and the second flow channel 12.

[0033] The flow guiding unit 2 is located between the first flow channel 11 and the second flow channel 12, and includes multiple pressure relief plates 21, a movable plate 22 slidably connected inside the pressure relief plate 21, a limiting block 23 disposed at the end of the movable plate 22, and a pressure relief component 24 disposed in the middle part of the movable plate 22.

[0034] In one embodiment provided in this application, the first flow channel 11 and the second flow channel 12 have the same structure and are arranged in reverse mirror image;

[0035] The first flow channel 11 includes multiple main pipes 111, a connecting pipe 112 disposed in the middle of the main pipes 111, sealing rings 113 disposed on both axial sides of the connecting pipe 112, and fixing discs 114 disposed on the upper and lower sides of the connecting pipe 112.

[0036] In this embodiment, the first flow channel 11 and the second flow channel 12 are arranged in a reverse mirror symmetrical manner, each including multiple sets of parallel main pipes 111, with each set of main pipes connected in series via connecting pipes 112. Sealing rings 113 are fixedly sleeved on both axial sides of the connecting pipes 112 to prevent fluid leakage; fixing discs 114 are fixed on the upper and lower sides of the connecting pipes 112 to support the pressure relief plate 21 and limit its displacement. The first branch pipe 13 and the second branch pipe 14 are located at the upper and lower ends of the first flow channel 11 and the second flow channel 12, respectively, and the circulation of fluid between the two flow channels is achieved by opening the valves of the first branch pipe 13 and the second branch pipe 14.

[0037] Preferably, each set of connecting pipes 112 is connected to a set of pressure relief plates 21, which are distributed along the centerline of the connecting pipes 112. A movable plate 22 is slidably embedded inside each set of pressure relief plates 21. The pressure relief plates 21 are slidably embedded in the vertical plane of the horizontal axis of the connecting pipes 112, and are vertically positioned within the cavity of the connecting pipes 112. When the pressure in the connecting pipes 112 is too high, causing the flow rate to be too fast, the pressure relief plates 21 will be pushed up by the flow rate, which will then drive the movable plate 22 to move. One end of the movable plate 22 is slidably embedded inside the pressure relief plate 21, while the other end is located at the end of the connecting pipe 112 in the second flow channel 12. A limiting block 23 is slidably connected to this end, which is used to limit the sliding stroke of the movable plate 22; a pressure relief assembly 24 is embedded in the middle, which consists of elastic sealing plates such as valves and valve discs.

[0038] Preferably, the pressure relief assembly 24 consists of an elastic sealing plate, such as a valve and a valve plate. By adjusting the opening degree of the metal valve plate, the opening degree of the valve in the first branch pipe 13 or the second branch pipe 14 can be changed, thereby achieving dynamic adjustment of the pressure balance in the first flow channel 11 and the second flow channel 12.

[0039] Specifically, the first flow channel 11 and the second flow channel 12 form a connected loop through the first branch pipe 13 and the second branch pipe 14, ensuring that the fluid circulates between the two flow channels. The flow guiding unit 2 is embedded between the first flow channel 11 and the second flow channel 12, and both ends of the pressure relief plate 21 are fixedly connected to the fixed disks 114 of the first flow channel 11 and the second flow channel 12, respectively. The moving plate 22 slides through the inner wall of the pressure relief plate 21, ensuring that it moves only axially when the pressure changes, avoiding deflection or jamming.

[0040] When the heat exchange station is operating, fluid flows through the first flow channel 11 and the second flow channel 12. Due to differences in pipeline design, such as the number of bends and pipe diameters, the flow velocity and pressure in the two flow channels may be unbalanced. When the pressure in the first flow channel 11 is higher than that in the second flow channel 12, or even exceeds a threshold, the fluid on the high-pressure side will push the pressure relief plate 21 upward, expanding the flow capacity inside the connecting pipe 112. This, in turn, pushes the moving plate 22 towards the low-pressure side, increasing the valve opening of the pressure relief assembly 24. This, in turn, opens the valve of the first branch pipe 13, allowing the fluid in the first flow channel 11 to flow into the second flow channel 12 through the first branch pipe 13, ultimately resetting the pressure balance between the first and second flow channels 11 and 12. Conversely, if the pressure in the second flow channel 12 is higher, the moving plate 22 slides towards the high-pressure side, opening the valve of the second branch pipe 14. This allows the fluid in the second flow channel 12 to flow into the first flow channel 11 through the second branch pipe 14, ultimately resetting the pressure balance between the first and second flow channels 11 and 12.

[0041] Through the dynamic adjustment of the pressure relief component 24, the pressure difference between the two channels is limited to a safe range. When the fluid flows in the first channel 11 and the second channel 12, part of the fluid is dynamically adjusted by the pressure relief plate 21 of the flow guiding unit 2 to control the opening and closing of the first branch pipe 13 or the second branch pipe 14, thereby regulating the fluid to enter the other channel and realizing bidirectional flow.

[0042] Reference Figures 2-4 As an optional embodiment, the connecting pipe 112 includes a groove 1121 on one side;

[0043] The fixed plate 114 includes a fixing groove 1141 that extends through its upper and lower end faces;

[0044] Furthermore, the fixed plate 114 is fixedly installed on the upper and lower end faces of the connecting pipe 112 by positioning bolts 31 on its periphery.

[0045] In one embodiment provided in this application, the pressure relief plate 21 is slidably engaged in the slide groove 1121;

[0046] The pressure relief plate 21 includes a pressure-receiving end 211 that is slidably disposed in the connecting pipe 112, and a driving end 212 that is slidably limited in the fixing groove 1141.

[0047] In this embodiment, a vertical groove 1121 is provided on one side wall of the connecting pipe 112 for vertically sliding and limiting the pressure relief plate 21. The fixing plate 114 is fixedly connected to the connecting pipe 112 at a certain height in the vertical direction by positioning bolts 31. The upper and lower end faces of the fixing plate 114 are provided with fixing grooves 1141 for embedding the pressure relief plate 21. The threaded holes of the positioning bolts 31 are distributed in the circumferential direction of the fixing plate 114 to ensure the coaxiality and stability of the fixing plate 114 and the connecting pipe 112.

[0048] Preferably, the pressure relief plate 21 comprises a pressure-receiving end 211 and a driving end 212, both integrally formed. The pressure-receiving end 211 is slidably embedded within a groove 1121, while the driving end 212 is slidably embedded within a fixing groove 1141. The depth of the groove 1121 matches the thickness of the pressure relief plate 21, ensuring that the pressure relief plate 21 can slide along the direction of the groove 1121 while preventing it from detaching. The width of the fixing groove 1141 matches the size of the driving end 212, ensuring that the driving end 212 can only slide along the direction of the fixing groove 1141, limiting its lateral displacement.

[0049] Preferably, the pressure-receiving end 211 is slidably embedded in the groove 1121 of the connecting pipe 112, and is directly exposed to the fluid. The flow-facing surface of the pressure-receiving end 211 is inclined, so that the fluid impacting it head-on will push the pressure-receiving end 211 vertically upward. When the fluid pressure increases, the pressure-receiving end 211 is subjected to an impact force and moves along the direction of the groove 1121. The sliding stroke of the driving end 212 is limited by the depth of the fixed groove 1141, ensuring that the movement range of the pressure relief plate 21 is controllable.

[0050] When the pressure-bearing end 211 of the pressure relief plate 21 moves due to fluid pressure, the driving end 212 slides synchronously within the fixed groove 1141, driving the moving plate 22 to move axially along the connecting pipe 112. Through the guiding effect of the sliding groove 1121 and the fixed groove 1141, the movement of the pressure relief plate 21 becomes more stable, thereby achieving the adjustment of the flow velocity and pressure within a single pipe of the connecting pipe 112, ensuring the accuracy and response speed of pressure regulation.

[0051] Reference Figures 1-6 As an optional embodiment, the movable plate 22 includes a transmission end 221 that is slidably engaged with the drive end 212, an engagement portion 222 protruding on one side of the transmission end 221, and a reset end 223 protruding on the other side of the engagement portion 222.

[0052] In one embodiment provided in this application, the drive end 212 includes an inclined block 2121 disposed on its inner side and a limiting groove 2122 formed at both ends of the drive end 212.

[0053] In one embodiment provided in this application, the transmission end 221 includes an inclined surface 2211 disposed on one side of its end;

[0054] The inclined plane 2211 is matched with the inclined plane of the inclined block 2121.

[0055] In one embodiment provided in this application, the pressure relief assembly 24 includes a docking valve 241 connected between the first branch pipe 13 and the second branch pipe 14, a butterfly valve 242 disposed in the inner cavity of the docking valve 241, a gear 243 disposed on the valve stem of the butterfly valve 242, and a coupling 244 axially connected to the gear 243.

[0056] Gear 243 meshes with meshing part 222.

[0057] In one embodiment provided in this application, the limiting block 23 includes a fixed end 231 fixedly limited at the center of the fixed disk 114, and a snap-fit ​​end 232 protruding from the bottom of the fixed end 231.

[0058] In one embodiment provided in this application, the reset end 223 is slidably limited within the snap-fit ​​end 232, and a spring M is fixedly connected to the end of the reset end 223.

[0059] In this embodiment, the transmission end 221 is slidably embedded in the limiting groove 2122 of the drive end 212, and its end is provided with an inclined surface 2211, which cooperates with the inclined surface of the inclined block 2121 of the drive end 212. The transmission end 221 converts the linear motion of the drive end 212 into the lateral movement of the moving plate 22 through the inclination angle of the inclined surface 2211. The meshing part 222 protrudes from one side of the transmission end 221, and its tooth structure meshes with the gear 243 of the pressure relief assembly 24. The tooth pitch of the meshing part 222 matches the module of the gear 243 to ensure maximum transmission efficiency. The reset end 223 is slidably limited in the snap-fit ​​end 232 of the limiting block 23, and a spring M is fixedly connected to its end.

[0060] Preferably, the spring M is made of a highly elastic, high-temperature resistant material such as silicone or polyurethane, and is used to automatically reset the moving plate 22 after the pressure is restored.

[0061] Preferably, the wedge block 2121 is embedded inside the drive end 212, and its inclined surface forms a wedge-shaped fit with the inclined surface 2211 of the transmission end 221, ensuring that the linear movement of the drive end 212 can directly drive the transmission end 221 to move. The limiting groove 2122 is formed at both ends of the drive end 212 to embed into the transmission end 221 and limit its lateral displacement, ensuring that the transmission end 221 slides only along the axial direction.

[0062] Furthermore, the docking valve 241 is connected to the first branch pipe 13 and the second branch pipe 14 respectively, serving as the core control component of the fluid channel. A butterfly valve 242 is installed inside the docking valve 241, and its valve stem is linked to the meshing part 222 via a gear 243. The gear 243 is mounted on the valve stem of the butterfly valve 242, and its rotation angle directly controls the opening degree of the butterfly valve 242.

[0063] Preferably, the coupling 244 can be axially connected to an external motor to directly control the opening degree of the butterfly valve 242.

[0064] The fixed end 231 is fixedly positioned at the center of the fixed plate 114 and is tightly connected to the fixed plate 114 by the positioning bolt 31. The snap-fit ​​end 232 protrudes from the bottom of the fixed end 231 and is used to embed the reset end 223 and provide a guiding function.

[0065] The pressure in the first flow channel 11 is too high: Fluid impacts the pressure-bearing end 211 of the connecting pipe 112 on this side of the first flow channel 11. The driving end 212 slides upward along the fixed groove 1141, and the inclined surface of the wedge block 2121 pushes the transmission end 221 to move towards the low-pressure side. The movement of the transmission end 221 drives the meshing part 222 to rotate the gear 243, causing the butterfly valve 242 to gradually open, and the valve in the first branch pipe 13 to open. Fluid flows from the first flow channel 11 through the first branch pipe 13 to the second flow channel 12, reducing the pressure in the first flow channel 11.

[0066] If the pressure in the second flow channel 12 is too high: the drive end 212 slides downward along the fixed groove 1141, and the inclined surface of the wedge block 2121 pushes the transmission end 221 to move towards the high-pressure side. The movement of the transmission end 221 drives the meshing part 222 to rotate the gear 243, causing the butterfly valve 242 to gradually close and the valve in the second branch pipe 14 to open. Fluid flows from the second flow channel 12 to the first flow channel 11 through the second branch pipe 14, reducing the pressure in the second flow channel 12.

[0067] When the pressure returns to a safe range, the spring M pushes the reset end 223 to retract, which drives the transmission end 221 to reset. The inclined surface of the wedge block 2121 separates from the transmission end 221, the gear 243 disengages from the meshing part 222, and the butterfly valve 242 closes.

[0068] In summary, this invention directly senses fluid pressure at the pressure-bearing end 211 of the pressure relief plate 21, and drives the moving plate 22 in conjunction with the drive end 212. Combined with the wedge-shaped engagement of the inclined block 2121 and the inclined surface 2211, linear motion is converted into lateral displacement, driving the butterfly valve 242 of the pressure relief assembly 24 to open and close rapidly, achieving dynamic pressure change balance regulation. Compared to traditional manual adjustment or external control systems, this mechanical linkage design achieves dynamic balance without additional energy, significantly improving regulation efficiency. Furthermore, the valve switching of the first branch pipe 13 and the second branch pipe 14 controls the bidirectional circulation of fluid between the two channels. For example, when the pressure in the first channel 11 is too high, the fluid flows through the first branch pipe 13 to the second channel 12; conversely, the pressure decreases, preventing overload on one side of the pipeline.

[0069] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
