Description

Technical Field

[0001] This utility model relates to the field of flow regulation technology, and in particular to a flow regulation device for heating pipe networks. Background Technology

[0002] Flow regulation devices in heating networks are crucial equipment in centralized heating systems. These include static balancing valves, dynamic differential pressure balancing valves, dynamic flow balancing valves, and electric regulating valves. They are primarily used to precisely control and regulate the flow of hot water through various branches of the network or to individual users, achieving hydraulic and thermal balance. Their main function is to resolve hydraulic imbalances caused by factors such as network distance, resistance differences, and variations in user load (i.e., overheating at the heat source end and insufficient heating at the distant end), ensuring that heat is delivered to all users on demand and evenly.

[0003] Existing flow control valves are generally installed by mating the end flanges with the pipe end flanges. Since the flange specifications of different pipe ends are different, the flow control valve cannot be installed flexibly when the pipe specifications at the required installation location are different from the device specifications. This not only reduces the installation flexibility of the device, but also affects the subsequent overall use.

[0004] Therefore, it is necessary to provide a new flow regulation device for heating networks to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a heating network flow regulation device.

[0006] The heating network flow regulating device provided by this utility model includes: a flow valve, wherein each end of the flow valve is provided with a movable connecting conduit;

[0007] Both ends of the flow valve are provided with fixedly connected docking plates. The docking plates have an internal mounting groove. The inner wall of the mounting groove is threaded to one end of the docking guide tube. The outside of the docking plates is provided with multiple movable docking blocks.

[0008] The docking block has a fixedly connected protrusion on its exterior, a movablely connected insert block is inserted inside the docking block, and a docking rod is inserted between the insert block and the docking plate.

[0009] Preferably, the outer wall of the docking plate is provided with a fixedly connected support ring, one end of the support ring is provided with a fixedly connected protective cover, and the end of the protective cover away from the support ring is provided with a fixedly connected rubber ring.

[0010] Preferably, the mating disc also has symmetrically distributed mating half-rings, which can be fixed with bolts to form a complete mating ring, and the inner wall of the mating ring abuts against the outer wall of the rubber ring.

[0011] Preferably, the docking block has a slot inside, the inner wall of the slot abuts against and slides with the outer wall of the plug block, and both the slot and the plug block have a cross-shaped end cross section.

[0012] Preferably, the side wall of the docking plate is provided with a plurality of annularly distributed docking holes, and the inside of the insert block is provided with a through hole, and the inner wall specifications of the through hole are the same as the inner wall specifications of the docking holes.

[0013] Preferably, the outer wall of the docking conduit is provided with a sealing sheet for fixed connection.

[0014] Compared with related technologies, the heating network flow regulation device provided by this utility model has the following advantages:

[0015] 1. When installing this flow valve, the present invention allows it to be smoothly connected to pipes of various specifications, which not only reduces the phenomenon that the flow valve cannot be installed due to different external pipe specifications, but also improves the flexibility and applicability of the device during installation.

[0016] 2. After the flow valve is connected to the external pipeline, the present invention can take the matching half ring and put it on the outside of the pipeline. Then, the protective cover can be put on the outside of the joint and the rubber ring at its end can be inserted into the joint half ring. This can achieve the protection of the connection part, thereby reducing the impact of the nut of the connection part being exposed to the outside for a long time and rusting and locking, which will make it difficult to disassemble later.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 The present invention provides a heating network flow regulation device, which includes a flow valve 1.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 The flow valve 1 has a movable connecting conduit 2 inserted at both ends; both ends of the flow valve 1 have a fixed connecting plate 11, the inside of the connecting plate 11 has an installation groove 111, the inner wall of the installation groove 111 is threaded to one end of the connecting conduit 2, and the outside of the connecting plate 11 has a plurality of movable connecting blocks 3; the outside of the connecting block 3 has a fixed connecting protrusion 31, the inside of the connecting block 3 has a movable connecting insert 33, and a connecting rod 34 is inserted between the insert 33 and the connecting plate 11; the outer wall of the connecting conduit 2 has a fixed connecting sealing plate 21.

[0026] It should be noted that: by flexibly inserting the connecting conduit 2, when installing this flow valve 1, a connecting conduit 2 that is compatible with the external pipeline can be selected for installation. Then, it is inserted into the external pipeline. Next, the connecting block 3 can be removed and inserted into the flange of the external pipeline. Then, the insert block 33 is moved so that the through hole 331 inside is aligned with the connecting hole 112 on the flow valve 1. Then, the connecting rod 34 is inserted and fixed with a nut. The installation of the flow valve 1 can be completed smoothly. By adopting this design, the flow valve 1 can be smoothly connected with pipelines of various specifications during installation. This not only reduces the phenomenon that the flow valve 1 cannot be installed due to different external pipeline specifications, but also improves the flexibility and applicability of this device during installation.

[0027] In this embodiment, by setting the sealing plate 21, the flange at the end of the external pipe can achieve a seal between the flange and the connecting plate 11 by abutting against the sealing plate 21 on the outside of the connecting conduit 2, thereby improving the sealing performance of the connection between the two.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 4 The outer wall of the mating plate 11 is provided with a fixed support ring 41. One end of the support ring 41 is provided with a fixed protective cover 4, and the end of the protective cover 4 away from the support ring 41 is provided with a fixed rubber ring 42. The mating plate 11 is also provided with symmetrically distributed mating half rings 5. The mating half rings 5 ​​can form a complete mating ring by fixing with bolts, and the inner wall of the mating ring abuts against the outer wall of the rubber ring 42.

[0029] It should be noted that: by setting the docking half ring 5, when the two form a complete docking ring, the inner wall groove abuts against the outer wall of the rubber ring 42, which can fix the end of the protective cover 4 away from the docking plate 11, so that the protective cover 4 can stably cover and protect the connection between this device and the external pipeline.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4 The docking block 3 has a slot 32 inside. The inner wall of the slot 32 abuts against and slides with the outer wall of the plug 33. The end sections of both the slot 32 and the plug 33 are cross-shaped.

[0031] It should be noted that: by setting the cross-shaped insert 33, after the insert 33 is inserted into the slot 32, the cross-shaped structure can limit the insert 33 in the horizontal direction, thereby providing stable support for the subsequent connection of the docking rod 34.

[0032] By setting the slot 32, during installation, the insert 33 can be moved vertically along the slot 32, thereby allowing the through hole 331 in the insert 33 to move smoothly to the position opposite to the docking hole 112, so that the docking rod 34 can dock and fix the two together later.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 4 Multiple annularly distributed docking holes 112 are fixedly opened on the side wall of the docking plate 11, and a through hole 331 is opened inside the insert block 33, and the inner wall specifications of the through hole 331 are the same as the inner wall specifications of the docking hole 112.

[0034] It should be noted that by setting the through hole 331 and the mating hole 112 to the same specification, the mating rod 34 can smoothly abut against the inner walls of the two holes when connecting them, which can improve the stability of the connection.

[0035] The working principle of the heating network flow regulation device provided by this utility model is as follows:

[0036] When using this device, the operator can first take out the docking conduit 2 that is compatible with the external connection pipe, and then screw one end of the docking conduit 2 into the mounting groove 111 inside the docking plate 11 through the threaded structure. After the installation of the docking conduit 2 is completed, the other end of the docking pipe can be inserted into the inside of the pipe.

[0037] Then, the required mating block 3 can be removed, and the protrusion 31 on the outer wall of the mating block 3 can be inserted into the hole of the flange at the end of the pipe. Then, the insert block 33 can be slid inside the slot 32. After the mating rod 34 inside the insert block 33 moves to the position opposite to the mating hole 112 in the mating plate 11, the mating rod 34 can be pushed to insert it into the mating hole 112. Then, the nut can be removed and fitted onto the end of the mating pipe near the mating plate 11 until the outer wall of the nut abuts against the outer wall of the mating plate 11. The mating rod 34 can then be tightened. By repeating the above operation, the mating rod 34 can be fixed.

[0038] After the fixing of the connecting rod 34 is completed, the flange at the end of the external pipe can achieve the sealing of the connection between the flange and the connecting plate 11 by abutting against the sealing plate 21 on the outside of the connecting conduit 2, thereby improving the sealing performance of the connection between the two.

[0039] Then, the matching half-ring 5 can be taken out and the two matching half-rings 5 ​​can be put on the outside of the pipe and fixed with bolts, so that the two matching half-rings 5 ​​can form a complete matching ring. Then, one end of the protective cover 4 can be pulled to pass through the outside of the matching part. When the rubber ring 42 at the end of the protective cover 4 moves to the part that abuts against the outer wall of the matching half-ring 5, the rubber ring 42 can be pressed and embedded in the inside of the complete matching ring formed by the two matching half-rings 5, thereby realizing the protection of the outside of the joint node of the two, thus reducing the phenomenon of bolts and nuts at the connection part being exposed to the outside for a long time and rusting and locking.

[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
