Description

Technical Field

[0001] This application relates to the field of valve technology, and more specifically, to a conical flow-guiding anti-clogging electric regulating valve for thermal pipeline networks. Background Technology

[0002] In fields such as centralized heating and industrial heat transmission, heat pipe networks are responsible for transporting heat energy media such as hot water or steam. As the core control component of the pipe network system, the performance of electric regulating valves directly affects the efficiency, stability and safety of heat energy transmission.

[0003] In the complex operating conditions of heating networks, existing electric regulating valves are prone to blockages due to the presence of impurities such as rust, scale, and silt in the heating network medium. These impurities tend to accumulate on the valve seat sealing surface and at the corners of the flow channel. Once blockage occurs, it can lead to flow regulation failure and temperature imbalance in the heating area, or even valve jamming and the need for network shutdown for maintenance. This not only affects users' normal heating but also incurs high maintenance costs. Utility Model Content

[0004] To address the aforementioned issues, this application provides a conical flow-guiding anti-clogging electric regulating valve for heating pipe networks.

[0005] The technical solution provided in this application for a cone-shaped flow-guiding anti-clogging electric regulating valve for heating pipe networks is as follows:

[0006] A conical flow-guiding anti-clogging electric regulating valve for heating pipe networks includes a valve body, a connecting seat connected to one side of the valve body, filter components on both sides of the valve body, and a flow regulating component on one side of the connecting seat.

[0007] The filter assembly includes two filter screens, which are used to filter impurities.

[0008] Furthermore, the cross-sectional shape of the valve body is set to be conical.

[0009] Furthermore, the valve body has openings at both ends, and a flange is connected to one side of each opening, with each filter screen located on one side of the corresponding flange.

[0010] Furthermore, each filter screen has a fixed ring on its outer wall, and each fixed ring has multiple mounting blocks on its outer wall.

[0011] Furthermore, each flange has multiple slots on one side, each slot is inserted into a corresponding mounting block, each slot has a rotating shaft fixedly connected to one side, each rotating shaft has a fixed protrusion rotatably connected to its outer wall, and each rotating shaft has a friction block on its outer wall.

[0012] Through the above technical solution, the two filter screens with different mesh sizes in the filter assembly achieve graded filtration.

[0013] Furthermore, the flow regulating component includes a regulating plug, and the valve body has an internal flow port with baffles on both sides. One side of each baffle is fixedly connected to the inner wall of the valve body, and the structure of the flow port is adapted to the structure of the regulating plug.

[0014] Furthermore, a fixed seat is fixedly connected to one side of the connecting seat, and a square limiting groove is opened inside the fixed seat. A square block is slidably connected inside the square limiting groove, and a limiting plate is fixedly connected to the top of the square block.

[0015] Furthermore, a fixed frame is fixedly connected to the top of the fixed base, a motor is fixedly connected to the top of the fixed frame, the output end of the motor passes through the fixed frame and is fixedly connected to a threaded rod, the threaded rod passes through the limiting plate and is threadedly connected to the square block, and a connecting rod is fixedly connected to the bottom of the square block, the connecting rod passes through one side of the fixed base and is fixedly connected to one side of the adjusting plug.

[0016] The above technical solutions enable automated control of the opening and closing of the flow outlet, and can match the flow regulation needs of the heating network as ambient temperature and heating demand change.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) This utility model achieves graded filtration by using two filter screens with different mesh sizes in the filter assembly. The large mesh filter screen first intercepts large impurities to prevent them from impacting and scratching subsequent components, while the small mesh filter screen filters out fine impurities, thus achieving comprehensive removal of impurities in the medium. Combined with the characteristic of tapered flow channel to reduce impurity retention, it greatly reduces the risk of valve blockage. At the same time, the filter screen is quickly fixed by the structure of the mounting block and the slot, and the fixing protrusion. It can be installed and disassembled without tools. In the daily maintenance of the thermal pipeline, cleaning or replacing the filter screen blockage, it can significantly shorten the operation time and reduce the maintenance cost. Moreover, it is fixed firmly and reliably, which can ensure that the filter screen works stably under the impact of the medium, continuously ensuring the efficient and safe operation of valves and thermal pipelines, and extending the service life of equipment.

[0019] (2) This utility model uses a motor in the flow regulating component to drive the threaded rod to rotate, and with the sliding limit of the square block in the square limiting groove, the rotational motion is precisely converted into the up and down linear motion of the regulating plug, so as to realize the automatic control of the opening and closing degree of the flow port. It can match the flow regulation requirements of the heating network as the ambient temperature and heat demand change. At the same time, by adapting the regulating plug to the flow port structure and combining the baffle to limit the flow range of the medium, the medium flow can be stably controlled to avoid flow fluctuations. The overall structure is stable and reliable in operation, and the flow regulation can be completed without manual intervention, which reduces labor costs and improves the intelligence and efficiency of the operation of the heating network.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figures 1-4 A conical flow guide anti-clogging electric regulating valve for heating pipe networks includes a valve body 1, a connecting seat 2 connected to one side of the valve body 1, filter components on both sides of the valve body 1, and a flow regulating component on one side of the connecting seat 2.

[0028] The filter assembly includes two filter screens 13, which are used to filter impurities.

[0029] Reference Figures 1-5 The cross-sectional shape of the valve body 1 is set to be conical.

[0030] The conical structure guides the flow of media (such as hot water and steam) in the heating network more smoothly, creating an orderly flow effect within the valve body. This reduces turbulence and energy consumption caused by abrupt changes in the flow path, improving the efficiency of media delivery. At the same time, the conical flow path utilizes the inherent flow inertia of the media, allowing impurities to flow more easily towards the outlet. Combined with the filter screen 13, this reduces the risk of localized accumulation and blockage of impurities within the valve body, maintaining the long-term stable operation of the valve.

[0031] Reference Figures 1-5 The valve body 1 has openings 12 at both ends. Each opening 12 is connected to a flange 19 on one side. Each filter screen 13 is located on one side of the corresponding flange 19. Each filter screen 13 has a fixed ring 14 fixedly connected to its outer wall. Each fixed ring 14 has multiple mounting blocks 15 fixedly connected to its outer wall. Each flange 19 has multiple slots 16 on one side. Each slot 16 is inserted into the corresponding mounting block 15. Each slot 16 has a rotating shaft 17 fixedly connected to one side. Each rotating shaft 17 has a fixed protrusion 18 rotatably connected to its outer wall. Each rotating shaft 17 has a friction block on its outer wall.

[0032] Among them, the mesh size of the filter screen 13 located inside the smaller inner diameter opening 12 of the valve body 1 is smaller than that of the filter screen 13 located inside the larger inner diameter opening 12.

[0033] The filter assembly can filter impurities in the heating network. Specifically, when the medium (such as hot water, steam, etc.) in the heating network flows through the valve body 1, it first passes through the filter screen 13 at the larger inner diameter opening 12. The filter screen 13 has larger mesh size, which can first intercept larger impurities in the medium (such as large pieces of rust, mud, etc.), avoiding these large particles from impacting or scratching subsequent flow channels and components. Subsequently, the medium flows smoothly to the smaller inner diameter opening 12 under the guidance of the conical valve body 1. The filter screen 13 at this opening 12 has smaller mesh size, which can further filter smaller particles of impurities in the medium (such as fine iron filings, scale particles, etc.), achieving graded filtration from large to small.

[0034] Meanwhile, each filter screen 13 can be quickly installed and removed. The specific operation method is as follows: when the filter screen 13 needs to be installed, first align the filter screen 13 with the flange 19 through the fixing ring 14, so that the multiple mounting blocks 15 on the outer wall of the fixing ring 14 are accurately inserted into the corresponding slots 16 on one side of the flange 19, ensuring that the filter screen 13 fits the flange 19 and is in a stable position. Then, rotate the fixing protrusion 18 around the rotating shaft 17 on one side of the slot 16 until the fixing protrusion 18 is tightly pressed against the surface of the mounting block 15. The friction block on the outer wall of the rotating shaft 17 will increase the rotation resistance, keep the fixing protrusion 18 in a fixed state, and prevent the filter screen 13 from loosening under the impact of the medium, thus completing the installation.

[0035] When it is necessary to disassemble the filter screen 13, rotate the fixing protrusion 18 to disengage it from the mounting block 15, and then pull the mounting block 15 out of the slot 16 to quickly remove the filter screen 13. This operation method does not require the use of wrenches or other tools, which is convenient for regular maintenance of the heating network and for cleaning or replacing the filter screen 13 when it is clogged. For example, during the pipeline maintenance before the heating season, maintenance personnel can quickly disassemble the filter screen 13 to remove the attached rust, scale and other impurities. After the maintenance is completed, it can be quickly reinstalled, which greatly shortens the maintenance time and ensures the continuous and stable operation of the heating network.

[0036] The filter assembly achieves graded filtration through two filter screens 13 with different mesh sizes. The larger mesh screen 13 first intercepts large impurities, preventing them from impacting and scratching subsequent components, while the smaller mesh screen 13 filters out finer impurities, achieving comprehensive removal of impurities from the medium. Combined with the tapered flow channel's characteristic of reducing impurity retention, this significantly reduces the risk of valve blockage. Furthermore, the filter screen 13's quick-fixing structure, achieved through the insertion of the mounting block 15 into the slot 16 and the fixing protrusion 18, allows for tool-free installation and disassembly. This significantly shortens operation time and reduces maintenance costs during routine maintenance of the heating network and during cleaning or replacement of clogged filter screens 13. The filter screen 13's secure and reliable fixation ensures stable operation even under media impact, continuously guaranteeing the efficient and safe operation of valves and the heating network, and extending equipment lifespan.

[0037] Reference Figures 1-4The flow regulating component includes a regulating plug 11. A flow port 3 is provided inside the valve body 1. A partition 20 is provided on both sides of the flow port 3. One side of each partition 20 is fixedly connected to the inner wall of the valve body 1. The structure of the flow port 3 is adapted to the structure of the regulating plug 11. A fixed seat 4 is fixedly connected to one side of the connecting seat 2. A square limiting groove 9 is provided inside the fixed seat 4. A square block 21 is slidably connected inside the square limiting groove 9. A limiting plate 8 is fixedly connected to the top of the square block 21. A fixed frame 5 is fixedly connected to the top of the fixed seat 4. A motor 6 is fixedly connected to the top of the fixed frame 5. A threaded rod 7 is fixedly connected after the output end of the motor 6 passes through the fixed frame 5. The threaded rod 7 passes through the limiting plate 8 and is threadedly connected to the square block 21. A connecting rod 10 is fixedly connected to the bottom of the square block 21. The connecting rod 10 passes through one side of the fixed seat 4 and is fixedly connected to one side of the regulating plug 11.

[0038] The flow regulation component enables automatic flow regulation of the valve body 1. Specifically, when the flow rate of the medium within the valve body 1 needs adjustment, the motor 6 starts and drives the threaded rod 7 at the output end to rotate. Since the threaded rod 7 is threadedly connected to the square block 21, and the square block 21 slides within the square limiting groove 9 inside the fixed seat 4 (the square structure prevents the square block 21 from rotating with the threaded rod 7), the rotation of the threaded rod 7 is converted into the vertical linear motion of the square block 21. As the square block 21 moves up and down, the connecting rod 10 at the bottom drives the regulating plug 11 to move synchronously up and down. The structure of the regulating plug 11 is adapted to the internal flow port 3 of the valve body 1. The partitions 20 on both sides of the flow port 3 help limit the flow range of the medium. When the regulating plug 11 moves upward, the gap between it and the flow port 3 increases, increasing the flow rate of the medium; when the regulating plug 11 moves downward, the gap decreases, reducing the flow rate of the medium. Thus, the forward and reverse rotation of the motor 6 precisely controls the position of the regulating plug 11, achieving automatic adjustment of the flow rate of the medium within the valve body 1 and meeting the flow requirements of the heating network under different operating conditions.

[0039] The motor 6 in the flow regulation component drives the threaded rod 7 to rotate, which, in conjunction with the sliding limit of the square block 21 in the square limiting groove 9, precisely converts the rotational motion into the up-and-down linear motion of the regulating plug 11. This achieves automated control of the opening and closing degree of the flow port 3, matching the flow regulation needs of the heating network as ambient temperature and heating demand change. At the same time, through the structural adaptation between the regulating plug 11 and the flow port 3, combined with the limitation of the medium flow range by the baffle 20, the medium flow rate can be stably controlled, avoiding flow fluctuations. The overall structure operates stably and reliably, and flow regulation can be completed without manual intervention, reducing labor costs and improving the intelligence and efficiency of the heating network operation.

[0040] Working principle: When the medium (such as hot water, steam, etc.) in the heating network flows through the valve body 1, it first passes through the filter screen 13 at the larger inner diameter opening 12. The filter screen 13 has larger mesh size, which can first intercept larger impurities in the medium (such as large pieces of rust, mud and sand), avoiding these large particles of impurities from impacting or scratching the subsequent flow channels and components. Subsequently, the medium flows smoothly to the smaller inner diameter opening 12 under the guidance of the conical valve body 1. The filter screen 13 at this opening 12 has smaller mesh size, which can further filter smaller particles of impurities in the medium (such as fine iron filings, scale particles, etc.), realizing graded filtration from large to small.

[0041] Meanwhile, when the filter screen 13 needs to be installed, first align the filter screen 13 with the flange 19 through the fixing ring 14, so that the multiple mounting blocks 15 on the outer wall of the fixing ring 14 are accurately inserted into the corresponding slots 16 on one side of the flange 19, ensuring that the filter screen 13 fits the flange 19 and is in a stable position. Then, rotate the fixing protrusion 18 around the rotating shaft 17 on one side of the slot 16 until the fixing protrusion 18 is tightly pressed against the surface of the mounting block 15. The friction block on the outer wall of the rotating shaft 17 will increase the rotation resistance, keeping the fixing protrusion 18 in a fixed state, preventing the filter screen 13 from loosening under the impact of the medium, and completing the installation.

[0042] When it is necessary to disassemble the filter screen 13, rotate the fixing protrusion 18 to disengage it from the mounting block 15, and then pull the mounting block 15 out of the slot 16 to quickly remove the filter screen 13. This operation method does not require the use of wrenches or other tools, which is convenient for regular maintenance of the heating network and for cleaning or replacing the filter screen 13 when it is clogged. For example, during the pipeline maintenance before the heating season, maintenance personnel can quickly disassemble the filter screen 13 to remove the attached rust, scale and other impurities. After the maintenance is completed, it can be quickly reinstalled, which greatly shortens the maintenance time and ensures the continuous and stable operation of the heating network.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
