Technical Field

[0001] This utility model relates to the field of heat meter technology, and more specifically, to a heat meter with a layered flow control structure. Background Technology

[0002] The purpose of a heat meter with a layered flow control structure is to precisely adjust and control the flow rate within the heat meter. Through the layered structure, external interference can be effectively reduced, ensuring the accuracy of flow rate adjustment and allowing for flexible adjustment of different flow rates according to requirements. At the same time, this structure can also enhance the heat meter's sealing performance, preventing flow leakage or errors, ensuring stable operation of the equipment under complex working conditions, and improving its measurement accuracy and reliability.

[0003] Existing heat meters with layered flow control structures lack precision and stability in flow regulation. In particular, when faced with different flow requirements, the existing flow regulation structure cannot effectively control external interference, resulting in insufficient flow control and unsatisfactory flow regulation performance, failing to meet the needs of high-precision flow control. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat meter with a layered flow control structure. By setting a sliding sealing limiting plate between the first limiting frame and the second limiting frame to adjust the flow rate and direction, the flow rate can be precisely controlled, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat meter with a layered flow control structure, comprising a main body, wherein the main body includes a first flow guide chamber, a second flow guide chamber is connected to the bottom of the first flow guide chamber, and an inlet pipe and an outlet pipe are respectively connected to both sides of the first and second flow guide chambers;

[0006] A diversion mechanism is fixedly installed inside the main body, and a drive mechanism is provided at the bottom of the diversion mechanism;

[0007] The diversion mechanism includes a first limiting frame fixedly installed at the horizontal centerline position of the first and second diversion chambers. The interior of the first limiting frame is cylindrical, and a first through groove is formed on the outer wall of the first limiting frame. A second limiting frame is fixedly installed inside the first limiting frame, and a second through groove is formed at the vertical centerline position of the second limiting frame. There is a gap between the first and second limiting frames. A sealing limiting plate is installed between the first and second limiting frames in a sliding state. A first threaded rod is rotatably installed at the horizontal centerline position of the first limiting frame. One end of the first threaded rod is fixedly connected to a second threaded rod rotatably connected to the first limiting frame. The outer walls of both the first and second threaded rods are engaged with internal threaded sleeves, and the outer walls of the internal threaded sleeves are hinged to support brackets that are hinged to the sealing limiting plate.

[0008] In a preferred embodiment, the number of sealing limiting plates is set to two, and both sealing limiting plates are arranged symmetrically about the horizontal center line of the first limiting frame.

[0009] In a preferred embodiment, the horizontal width of the first through groove is greater than the horizontal width of the second through groove, and the first limiting frame, the second limiting frame, and the sealing limiting plate are all arranged in a concentric circle.

[0010] In a preferred embodiment, the horizontal width of the sealing limiting plate is greater than the horizontal width of the second through groove and is consistent with the horizontal width of the first through groove, and the thickness of the sealing limiting plate is less than the length of the gap between the first limiting frame and the second limiting frame.

[0011] In a preferred embodiment, the thread directions of the outer walls of the first threaded rod and the second threaded rod are opposite, and the two supports provided on the outer walls of the first threaded rod and the second threaded rod are both inclined in normal conditions, and the two supports provided on the outer walls of the first threaded rod and the second threaded rod are symmetrical about the vertical center line of the sealing limit plate.

[0012] In a preferred embodiment, the driving mechanism includes a first bevel gear fixedly installed at the junction of the first threaded rod and the second threaded rod, the outer wall of the first bevel gear meshing with a second bevel gear, and a vertically positioned limiting support rod fixedly connected to the bottom of the second bevel gear.

[0013] In a preferred embodiment, the sealing limiting plate is arranged in a sliding state on the outer wall of the limiting support rod, and a transmission gear is fixedly installed at the bottom of the limiting support rod. The outer wall of the transmission gear is meshed with an electric gear that is rotatably connected to the second guide chamber.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model adjusts the flow rate by setting a sliding sealing limiting plate between the first limiting frame and the second limiting frame. When the sealing limiting plate blocks the first through groove, precise control of the flow rate can be achieved. When the sealing limiting plate moves closer to the outer wall of the second limiting frame, the size of the gap between the first limiting frame and the second limiting frame can be adjusted, thereby adjusting the flow rate of the flow from the inner cavity of the first guide chamber to the inner cavity of the second guide chamber. This effectively reduces external interference with the flow control and ensures more precise flow control of the heat meter.

[0016] 2. This utility model uses a first threaded rod and a second threaded rod to drive the sealing limit plate to move up and down, allowing it to slide and adjust the flow rate and direction. Users can easily adjust the flow control of the heat meter, making flow regulation smoother and more flexible. This design not only improves operational convenience but also enhances the practicality of the equipment. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figure 1-4 A heat meter with a stratified flow control structure, referencing Figure 1 As shown, it includes a main body 1, which includes a first flow guide chamber 101. The bottom of the first flow guide chamber 101 is connected to a second flow guide chamber 102. The two sides of the first flow guide chamber 101 and the second flow guide chamber 102 are respectively connected to an inlet pipe 103 and an outlet pipe 104.

[0024] The main body 1 has a diversion mechanism 2 fixedly installed inside, and the bottom of the diversion mechanism 2 is provided with a drive mechanism 3;

[0025] Combination Figure 2 As shown, the diversion mechanism 2 includes a first limiting frame 21 fixedly installed at the horizontal centerline position of the first diversion chamber 101 and the second diversion chamber 102. The interior of the first limiting frame 21 is cylindrical, and a first through groove 22 is formed on the outer wall of the first limiting frame 21. A second limiting frame 23 is fixedly installed inside the first limiting frame 21, and a second through groove 24 is formed at the vertical centerline position of the second limiting frame 23. There is a gap between the first limiting frame 21 and the second limiting frame 23. A sealing limiting plate 25 is installed between the first limiting frame 21 and the second limiting frame 23 in a sliding state. Figure 3-4 As shown, a first threaded rod 26 is rotatably mounted on the horizontal centerline of the first limiting frame 21. One end of the first threaded rod 26 is fixedly connected to a second threaded rod 27 rotatably connected to the first limiting frame 21. Both the outer walls of the first threaded rod 26 and the second threaded rod 27 are engaged with internal threaded sleeves 28, and the outer walls of the internal threaded sleeves 28 are hinged to support brackets 29 that are hinged to the sealing limiting plate 25. In actual use, by driving the sealing limiting plate 25 up and down, the sealing limiting plate 25 can be blocked at the first through groove 22 or moved to fit against the outer wall of the second limiting frame 23, causing the sealing limiting plate 25 to approach and fit against the first through groove 22. When the second limiting frame 23 is on the outer wall, the size of the gap between the first limiting frame 21 and the second limiting frame 23 can be adjusted, thereby reducing the flow rate from the inner cavity of the first guiding chamber 101 into the inner cavity of the second guiding chamber 102. When the sealing limiting plate 25 moves and engages with the first through groove 22, the first through groove 22 can be completely blocked, thereby forming a sealing barrier with the first limiting frame 21 and blocking the flow between the first guiding chamber 101 and the second guiding chamber 102. This ensures that the flow rate can only circulate within the inner cavity of the first guiding chamber 101, making adjustment very convenient and easier for practical use.

[0026] Furthermore, the number of sealing limit plates 25 is set to two, and the two sealing limit plates 25 are symmetrically arranged about the horizontal center line of the first limit frame 21. The purpose of this arrangement is to ensure that when the first limit frame 21 is blocked, the upper and lower sides of the first through groove 22 opened inside it can be blocked simultaneously, thereby enhancing the sealing between the first flow chamber 101 and the second flow chamber 102.

[0027] The horizontal width of the first through groove 22 is greater than the horizontal width of the second through groove 24. The first limiting frame 21, the second limiting frame 23, and the sealing limiting plate 25 are all arranged in a concentric circle. At the same time, the horizontal width of the sealing limiting plate 25 is greater than the horizontal width of the second through groove 24 and is consistent with the horizontal width of the first through groove 22. The thickness of the sealing limiting plate 25 is less than the length of the gap between the first limiting frame 21 and the second limiting frame 23. The purpose of this arrangement is to make the sealing limiting plate 25 move up and down more smoothly inside the gap between the second limiting frame 23 and the first limiting frame 21.

[0028] Furthermore, the threads on the outer walls of the first threaded rod 26 and the second threaded rod 27 are arranged in opposite directions, and the two support brackets 29 on the outer walls of the first threaded rod 26 and the second threaded rod 27 are both inclined in normal conditions. The two support brackets 29 on the outer walls of the first threaded rod 26 and the second threaded rod 27 are symmetrical about the vertical center line of the sealing limit plate 25. The purpose of this arrangement is to allow the support brackets 29 on their outer walls to gradually adjust from an inclined state to a vertical state when the first threaded rod 26 and the second threaded rod 27 are driven to rotate, thereby lifting and moving the sealing limit plate 25 up and down, which is very convenient to operate.

[0029] As a further expansion of this plan, refer to Figure 4 and Figure 3As shown, the drive mechanism 3 includes a first bevel gear 31 fixedly installed at the junction of the first threaded rod 26 and the second threaded rod 27. A second bevel gear 32 meshes with the outer wall of the first bevel gear 31. A vertically positioned limiting support rod 33 is fixedly connected to the bottom of the second bevel gear 32. In actual use, driving the limiting support rod 33 to rotate causes the second bevel gear 32 to drive the first bevel gear 31 to rotate, thereby synchronously driving the first threaded rod 26 and the second threaded rod 27 to rotate. The sealing limiting plate 25 limits the support... The outer wall of the rod 33 is set in a sliding state. A transmission gear 34 is fixedly installed at the bottom of the limiting support rod 33. The outer wall of the transmission gear 34 is meshed with an electric gear 35 that is rotatably connected to the second guide chamber 102. In actual use, by starting the electric gear 35, the transmission gear 34 can be driven to rotate, which in turn causes the limiting support rod 33 to drive the second bevel gear 32 to rotate, so as to realize the synchronous rotation of the first threaded rod 26 and the second threaded rod 27, thereby driving the sealing limiting plate 25 to move up and down to adjust the flow rate and direction.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
