Description

Technical Field

[0001] This utility model relates to the field of flow regulation technology for secondary heating networks, and more specifically, to a flow regulation mechanism for secondary heating networks. Background Technology

[0002] The secondary heating network is a low-temperature hot water transmission network in a centralized heating system that connects heat exchange stations with end users (such as residential areas and commercial buildings). Its core function is to adapt the heat of the high-temperature water in the primary network to low-temperature hot water (usually in the range of 60-80℃) suitable for users after it has been heated by heat exchangers, and to directly supply users with the water to meet their heating or domestic hot water needs.

[0003] Existing flow regulation mechanisms for balancing secondary heating networks typically involve directly installing manual valves. Adjusting the flow usually requires manual intervention, which introduces significant errors and often fails to achieve the desired temperature. Therefore, we propose a flow regulation mechanism for secondary heating networks to address these issues. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a flow regulation mechanism for a secondary heating network. As the adjustment disc rotates more, the cross-section between the valve discs opens larger, thereby regulating the flow rate with small adjustment error and effectively adjusting to the required temperature.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A flow regulation mechanism for a secondary heating network includes a heating pipe and a mounting boss fixedly connected to the inner wall of the heating pipe. A valve plate with an annular structure is fixedly connected to the mounting boss, and a regular hexagonal guide groove is formed on the surface of the valve plate away from the mounting boss.

[0009] An adjusting disc is rotatably connected to the valve plate. A driven bevel gear is fixedly connected to the outer edge of the adjusting disc. A guide hole is provided in the radial position of the surface of the adjusting disc, and multiple guide holes are provided.

[0010] A valve disc is fitted between the valve plate and the regulating disc. A guide block is integrally formed on the edge of the valve disc and is slidably connected to the regular hexagonal guide groove. A guide column head is fixedly connected to the surface of the valve disc and is slidably connected to the guide hole.

[0011] A stepper motor is mounted on the outside of the heating pipe via a bracket, and the power output end of the stepper motor is connected to a driving bevel gear that meshes with the driven bevel gear.

[0012] Furthermore, the output end of the heating pipeline is connected to an electromagnetic flow meter via a flange.

[0013] Furthermore, the edge of the valve plate is integrally formed with a mounting flange, and the mounting flange is connected to the mounting boss by bolts;

[0014] A sealing gasket is pressed between the mounting flange and the mounting boss.

[0015] Furthermore, the outer wall of the valve plate is provided with a limiting flange.

[0016] Furthermore, the inner wall of the adjusting disc is provided with a limiting groove that engages with the limiting flange, and a sealing ring that fits against the limiting flange is embedded on the inner side of the limiting groove.

[0017] Furthermore, the valve disc is specifically provided in six parts.

[0018] Furthermore, a connecting shaft that passes through the heating pipe is fixedly connected to the active bevel gear, and a dynamic seal is installed at the part where the connecting shaft is combined with the heating pipe.

[0019] The connecting shaft is connected to the power output end of the stepper motor via a coupling.

[0020] 3. Beneficial Effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) In this scheme, by precisely controlling the angular displacement of the stepper motor, the active bevel gear and the driven bevel gear mesh to drive the adjustment plate to rotate relative to the valve plate. This allows the guide pin to slide in conjunction with the guide hole, and the guide block to slide in conjunction with the regular hexagonal guide groove on the valve plate. This allows multiple valve discs to fit together and slide in conjunction with their side walls, thereby opening the space in the center of the valve plate. The larger the amplitude of the adjustment plate rotation, the larger the cross section opened between the valve discs, thus achieving flow regulation. The regulation error is small, and it can effectively regulate to the required temperature.

[0023] (2) In this scheme, the flow rate of hot water after adjustment is monitored in real time by electromagnetic flow meter, and the flow rate is fed back to the controller. Thus, the controller can more accurately control the operation of stepper motor by analyzing and processing the data. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] Please see Figure 1-7 A flow regulation mechanism for a secondary heating network includes a heating pipe 1 and an mounting boss 2 fixedly connected to the inner wall of the heating pipe 1. A valve plate 3 with an annular structure is fixedly connected to the mounting boss 2. A regular hexagonal guide groove 4 is opened on the surface of the valve plate 3 away from the mounting boss 2.

[0036] An adjusting plate 6 is rotatably connected to the valve plate 3. A driven bevel gear 7 is fixedly connected to the outer edge of the adjusting plate 6. A guide hole 8 is provided in the radial position of the surface of the adjusting plate 6, and multiple guide holes 8 are provided.

[0037] A valve disc 11 is fitted between the valve plate 3 and the regulating plate 6. A guide block 12 is integrally formed on the edge of the valve disc 11 and is slidably connected to the regular hexagonal guide groove 4. A guide column head 13 is fixedly connected to the surface of the valve disc 11 and is slidably connected to the guide hole 8.

[0038] A stepper motor 14 is mounted on the outside of the heating pipe 1 via a bracket. The power output end of the stepper motor 14 is connected to a drive bevel gear 15 that meshes with the driven bevel gear 7.

[0039] It should be noted that when using this flow regulation mechanism for the secondary heating network, the stepper motor 14 is first connected to an external controller. By precisely controlling the angular displacement of the stepper motor 14, the active bevel gear 15 and the driven bevel gear 7 mesh to drive the regulating disc 6 to rotate relative to the valve plate 3. This causes the guide column head 13 to slide in conjunction with the guide hole 8, and simultaneously slides through the guide block 12 in conjunction with the regular hexagonal guide groove 4 opened on the valve plate 3. This allows the multiple valve discs 11 to slide against each other and their side walls, thereby opening the space in the center of the valve plate 3. The greater the rotation amplitude of the regulating disc 6, the larger the cross-section opened between the valve discs 11, thus achieving flow regulation with small adjustment error and effectively regulating to the required temperature.

[0040] like Figure 1 As shown, the output end of the heating pipeline 1 is connected to an electromagnetic flow meter 16 via a flange;

[0041] It should be noted that the electromagnetic flowmeter 16 monitors the flow rate of hot water after adjustment in real time and feeds the flow rate back to the controller. The controller can then analyze and process the data to more accurately control the operation of the stepper motor 14.

[0042] like Figure 2 As shown, the edge of the valve plate 3 is integrally formed with a mounting flange, and the mounting flange is connected to the mounting boss 2 by bolts;

[0043] A sealing gasket is pressed between the mounting flange and the mounting boss 2;

[0044] It should be noted that this facilitates the connection between the valve plate 3 and the mounting boss 2, while also ensuring the sealing of the connection.

[0045] like Figure 4 , Figure 5 As shown, the outer wall of the valve plate 3 is provided with a limiting flange 5, and the inner wall of the adjusting plate 6 is provided with a limiting groove 9 that engages with the limiting flange 5. A sealing ring 10 that fits with the limiting flange 5 is embedded on the inner side of the limiting groove 9.

[0046] It should be noted that while limiting the position of the regulating disc 6, the sealing of the joint between the regulating disc 6 and the valve plate 3 is ensured.

[0047] like Figure 2 As shown; a connecting shaft that passes through the heating pipe 1 is fixedly connected to the active bevel gear 15, and a dynamic seal is installed at the part where the connecting shaft and the heating pipe 1 are combined.

[0048] The connecting shaft is connected to the power output end of the stepper motor 14 via a coupling;

[0049] It should be noted that, while preventing leakage, the power transmitted by the stepper motor 14 is ensured to be transmitted normally to the drive bevel gear 15.

[0050] The valve disc 11 is specifically configured with six discs.

[0051] In use: First, connect the stepper motor 14 to an external controller. By precisely controlling the angular displacement of the stepper motor 14, the active bevel gear 15 meshes with the driven bevel gear 7 to drive the regulating disc 6 to rotate relative to the valve plate 3. This causes the guide pin 13 to slide in conjunction with the guide hole 8, and simultaneously slides through the guide block 12 in conjunction with the regular hexagonal guide groove 4 opened on the valve plate 3. This allows the multiple valve discs 11 to fit together and slide against their side walls, thereby opening the space in the center of the valve plate 3. The greater the rotation amplitude of the regulating disc 6, the larger the cross-section opened between the valve discs 11, thus achieving flow regulation.

[0052] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
