Description

Technical Field

[0001] This utility model relates to the field of water-saving technology, and in particular to a water-saving heating pipeline water flow regulating device. Background Technology

[0002] In heating systems, water flow regulation devices are key equipment for ensuring heating efficiency and the rational use of water resources. They precisely regulate parameters such as flow rate and pressure within the pipes to ensure effective heat transfer and reduce unnecessary water consumption.

[0003] Existing heating pipeline flow regulation devices typically consist of a pipe connection structure, flow regulating valves, and a control system. Pipe connections often use flange connections, where flanges on two pipe sections are fastened together with bolts and sealed with rubber gaskets. Traditional flange connections require tightening or loosening multiple bolts individually during installation and disassembly, which is cumbersome and time-consuming, increasing construction and maintenance costs. Furthermore, during long-term operation, bolts are susceptible to loosening due to vibration, leading to gasket failure and leakage. Therefore, a water-saving heating pipeline flow regulation device is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a water-saving heating pipeline water flow regulating device, which aims to improve the problems of cumbersome pipeline connection operations and easy failure of sealing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The locking pin is slidably connected to the middle of the slide groove, and the housing is fixedly connected to the outside of the outer shell;

[0012] As a further description of the above technical solution:

[0013] A spring rod is fixedly connected to the middle of the chute, and an inclined block is fixedly connected to the outside of the spring rod;

[0023] 1. In this utility model, the locking pin is inserted into the sliding groove, and the shell is rotated to make the locking pin engage with the groove, thereby connecting pipe one and pipe two. The sealing gasket on the outside of the connecting block fits tightly with the inside of the shell, effectively preventing water leakage at the connection. Rotating the shell in the opposite direction makes the locking pin disengage from the groove, allowing the pipe to be easily disassembled, improving the convenience and flexibility of maintenance.

[0024] 2. In this utility model, rotating the handle can drive the disc to rotate, thereby adjusting the size of the water flow channel in the pipeline.

[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. 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.

[0034] Reference Figures 1-6 An embodiment of this utility model is provided: a water-saving heating pipeline water flow regulating device, including a first pipeline 1 and a second pipeline 2. A connecting component is installed on the outside of the first pipeline 1, an regulating component is installed in the middle of the second pipeline 2, a valve seat 11 is fixedly connected to the outside of the second pipeline 2, and a shell 5 is fixedly connected to the outside of the valve seat 11.

[0035] The connecting assembly includes a connecting block 17, which is fixedly connected to the outside of pipe 1. A groove 15 is formed in the middle of the connecting block 17, and a slot 19 is provided in the middle of the groove 15. A housing 3 is rotatably connected to the outside of the connecting block 17, and a locking post 18 is fixedly connected inside the housing 3, engaging with the slot 19. The locking post 18 is slidably connected to the middle of the groove 15, and the housing 3 is fixedly connected to the outside of the outer shell 5. A spring rod 20 is fixedly connected to the middle of the groove 15, and a wedge block 21 is fixedly connected to the outside of the spring rod 20. During installation, the locking post 18 is inserted into the groove 15, and the housing 3 is rotated. Guided by the wedge block 21, the locking post 18 embeds into the slot 19. The spring rod 20 pushes the wedge block 21 to press the locking post 18 for fixation. During disassembly, the housing 3 is rotated in the opposite direction to disengage the locking post 18 from the slot 19, facilitating quick disassembly and effectively reducing the installation and maintenance costs of the heating system, as well as installation time and labor costs. One end of the outer casing 5 is fixedly connected to the outside of the casing 3. A limiting frame 8 is fixedly connected inside the outer casing 5. A valve stem 7 is slidably connected inside the limiting frame 8. A spring 10 is sleeved on the outside of the valve stem 7. A valve disc 9 is fixedly connected to the end of the valve stem 7. A washer 6 is fixedly connected inside the outer casing 5, contacting the valve disc 9. The washer 6 effectively prevents leakage at the connection point and when the valve is closed, reducing the system's water replenishment requirements and thus reducing water consumption, achieving water conservation. A support column 22 is fixedly connected to the outside of the limiting frame 8, and the support column 22 is fixedly connected to the inside of the outer casing 5. A sealing gasket 16 is fixedly connected to the outside of the connecting block 17, contacting the inside of the casing 3. Through the valve structure formed by the valve stem 7, spring 10, and valve disc 9, under the action of the spring 10, the valve disc 9 and the washer 6 are tightly fitted, ensuring sealing in the closed state. When water pressure or adjustment by the handle 4 acts on the valve stem 7, the valve disc 9 can precisely control the flow and volume of water. The inclined block 21 is in contact with the locking post 18.

[0036] Reference Figure 1 and Figure 3 The regulating component includes a fixed ring 12, which is fixedly connected to the middle of pipe 1. A handle 4 is rotatably connected to the middle of the fixed ring 12. A disc 13 is fixedly connected to the bottom of the handle 4, and a fixed block 14 is fixedly connected to the middle of the disc 13. The fixed block 14 is rotatably connected to the middle of the fixed ring 12. Rotating the handle 4 causes the bottom disc 13 and the fixed block 14 to rotate within the fixed ring 12. By changing the cross-sectional area of ​​the water flow channel in the pipe, the flow rate can be manually adjusted. The regulating component works in conjunction with the valve to adjust the water flow as needed, avoiding water waste caused by excessive flow.

[0037] Working principle: During installation, align the locking pin 18 inside the housing 3 with the slide groove 15 and insert it. Slide it along the slide groove 15 to the locking slot 19. Then rotate the housing 3, and the locking pin 18, guided by the inclined block 21, embeds into the locking slot 19, achieving a snap-fit ​​fixation. During this process, the spring rod 20 pushes the inclined block 21 to maintain pressure on the locking pin 18, ensuring a stable connection. At the same time, the sealing gasket 16 on the outside of the connecting block 17 fits tightly against the inner wall of the housing 3, forming a sealing layer to prevent water leakage. During disassembly, rotate the housing 3 in the opposite direction, and the locking pin 18 disengages from the locking slot 19, facilitating inspection and maintenance.

[0038] During adjustment, rotating the handle 4 causes the disc 13 and the fixed block 14 to rotate within the fixed ring 12, changing the cross-sectional area of ​​the water flow channel in the pipe and achieving manual flow regulation. When the water pressure pushes the valve stem 7 to compress the spring 10, the valve disc 9 moves away from the washer 6, allowing water to flow through; when the pressure decreases, the spring 10 returns to its original position, pushing the valve disc 9 to engage with the washer 6, shutting off the water flow. Furthermore, the limit frame 8 and the support column 22 ensure stable sliding of the valve stem 7, preventing displacement that could affect the sealing effect. Through the dual mechanism of handle 4 adjustment and automatic valve response, the flow rate can be flexibly controlled according to heating demand, avoiding water waste.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
