Description

Technical Field

[0001] This utility model relates to the field of valve structure, and more particularly to a valve structure for sewage pipelines. Background Technology

[0002] As a mechanical device that controls the flow of fluid in pipelines or equipment, a valve can control fluid parameters by changing the state of the flow channel. There are many reasons for using a specific valve structure in sewage pipelines. It can control water flow, cut off water flow during maintenance and other operations, and adjust the flow rate as needed to ensure the coordinated operation of sewage treatment processes. It can protect equipment and pipelines, prevent sewage backflow and impact, control pipeline pressure, and avoid system damage. It can also realize system functions, manage large sewage systems by zone, limit the scope of failure impact, and flexibly switch sewage treatment processes to optimize the treatment process.

[0003] Existing valves for sewage pipelines have diverse structures. Gate valves rely on rotating the valve stem to move the gate up and down along the axis, cutting off or guiding sewage by the contact or separation of the gate and the valve seat. Ball valves control opening and closing by rotating the ball so that the through hole on the ball coincides with or is perpendicular to the pipeline axis. Butterfly valves rotate the valve stem to drive the butterfly plate to rotate around the axis, and the butterfly plate is parallel or perpendicular to the pipeline axis to achieve full opening or full closing. Check valves automatically open and close the valve disc based on the flow of the medium. The valve disc is open when the flow is forward and closed when the flow is reverse. Regulating valves adjust the operating parameters such as flow rate and pressure by changing the flow area between the valve stem and valve core and the valve seat, based on the sewage flow rate, pressure and other parameters detected by the sensor.

[0004] In the actual use of valve structures for sewage pipelines, there is a significant and urgent problem that needs to be solved. Currently, whenever it is necessary to connect water pipes to equipment, it often relies on the collaborative work of multiple operators. These operators need to spend a lot of energy carefully aligning the water pipes precisely with the equipment interfaces. The process is tedious and time-consuming, and even a slight deviation requires readjustment. This not only wastes manpower but also seriously affects the overall work efficiency. Over time, this greatly reduces the operational efficiency of valve structures in sewage pipeline systems, making it difficult to meet the demands of modern sewage treatment for efficient and convenient operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a valve structure for sewage pipelines, aiming to improve the problem that multiple operators are required to align the water pipe with the equipment before connecting it during equipment use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a valve structure for sewage pipelines, comprising a pipeline, a protective box fixedly connected to the top of the pipeline, a valve slidably connected inside the protective box, a threaded rod fixedly connected to the top of the valve, a rotating assembly provided on the top of the protective box, a water pipe slidably connected to one end of the pipeline, flange rings fixedly connected to both ends of the pipeline, multiple fixing posts fixedly connected to one side of each flange ring, a fixing groove provided on the outer wall of each fixing post, multiple connecting grooves provided on one side of each flange ring, and multiple fixing assemblies provided inside each flange ring;

[0007] Each of the fixing components includes a fixing ring and a spring. The outer wall of each fixing ring is slidably connected to the inside of the flange ring. Each spring is disposed inside the flange ring. One end of each spring is fixedly connected to the inside of the flange ring, and the other end of each spring is fixedly connected to one side of the fixing ring.

[0008] As a further description of the above technical solution:

[0009] The rotating assembly includes a connecting column and a turntable. The bottom end of the connecting column is fixedly connected to the top of the protective box, and the bottom of the turntable is rotatably connected to the top end of the connecting column. The inner wall of the connecting column is threadedly connected to the outer wall of the threaded rod, and the inner wall of the turntable is threadedly connected to the outer wall of the threaded rod.

[0010] As a further description of the above technical solution:

[0011] Each flange ring is slidably connected to one side with a sealing ring one, and each flange ring is slidably connected to one side with a sealing ring two.

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

[0013] Each of the sealing rings has a sliding groove on one side, and each of the flange rings has multiple connecting strips fixedly connected to one side.

[0014] As a further description of the above technical solution:

[0015] Each of the connecting strips is fixedly connected to one side of a limiting strip, each limiting strip is slidably connected to a fixing pin inside, and each fixing pin is fixedly connected to a limiting plate on its outer wall.

[0016] As a further description of the above technical solution:

[0017] Each of the connecting strips is provided with a second spring inside, one end of each second spring is fixedly connected to the inside of the connecting strip, and the other end of each second spring is fixedly connected to one end of the fixing pin.

[0018] As a further description of the above technical solution:

[0019] The connecting strips are arranged in a ring array and fixedly connected to one side of the flange ring, and the outer wall of each fixing pin is slidably connected to the inside of the sealing ring.

[0020] As a further description of the above technical solution:

[0021] The outer wall of each of the limiting strips is slidably connected to the inside of the sliding groove, and the outer wall of each of the limiting plates is slidably connected to the inside of the limiting strip.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the fixing post on one side of the flange ring is first aligned with the connecting groove at one end of the water pipe. Then, the flange ring and the water pipe are brought closer together, so that the fixing post enters the connecting groove. During this period, the fixing ring is squeezed into the flange ring by the outer wall of the fixing post. When the fixing post enters the deepest part of the connecting groove, the fixing ring pops out under the action of the spring and slides into the fixing groove. This achieves the effect of calibrating the threaded hole between the flange ring by using the fixing post and the connecting groove when connecting the water pipe to the equipment during equipment use. This avoids the problem of needing multiple operators to align the water pipe and the equipment before connecting them during equipment use, thereby improving the efficiency of the valve structure used for sewage pipelines.

[0024] 2. In this utility model, first hold sealing ring one or sealing ring two and rotate it clockwise, so that its inner wall squeezes the fixing pin and retracts it into the limiting strip, unlocking sealing ring one or sealing ring two. When the limiting strip slides completely out of the sliding groove, pull sealing ring one or sealing ring two outward, thereby achieving the effect of easily removing and replacing the sealing ring during equipment use. This avoids the problem of water leakage in the pipeline caused by the sealing effect of the sealing ring decreasing with the extension of the usage time during equipment use, thus improving the practicality of the valve structure used in sewage pipelines.

Detailed Implementation

[0032] 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a valve structure for sewage pipelines, including a pipeline 1, a protective box 2 fixedly connected to the top of the pipeline 1 for accommodating a valve 3, a valve 3 slidably connected inside the protective box 2 for controlling the opening and closing of the pipeline 1, a threaded rod 4 fixedly connected to the top of the valve 3 for raising and lowering the valve 3, a rotating assembly provided on the top of the protective box 2, a water pipe 7 slidably connected to one end of the pipeline 1 for connecting to a water source, flange rings 8 fixedly connected to both ends of the pipeline 1 for connecting the water pipe 7, multiple fixing posts 9 fixedly connected to one side of each flange ring 8 for connecting to the water pipe 7, a fixing groove 10 opened on the outer wall of each fixing post 9 for accommodating a fixing ring 11, multiple connecting grooves 13 opened on one side of each flange ring 8 for connecting the fixing post 9, and multiple fixing assemblies provided inside each flange ring 8;

[0034] Each fixing component includes a fixing ring 11 and a spring 12. The outer wall of each fixing ring 11 is slidably connected to the inside of the flange ring 8 to fix the fixing column 9. Each spring 12 is disposed inside the flange ring 8 to provide elastic force to the fixing ring 11. One end of each spring 12 is fixedly connected to the inside of the flange ring 8, and the other end of each spring 12 is fixedly connected to one side of the fixing ring 11. The rotating component includes a connecting column 5 and a turntable 6. The bottom end of the connecting column 5 is fixedly connected to the top of the protective box 2 to connect the turntable 6. The bottom of the turntable 6 is rotatably connected to the top end of the connecting column 5 to drive the valve 3 to lift. The inner wall of the connecting column 5 is threadedly connected to the outer wall of the threaded rod 4, and the inner wall of the turntable 6 is threadedly connected to the outer wall of the threaded rod 4.

[0035] Specifically, when it is necessary to connect the equipment to the water pipe 7, the operator first aligns the fixing post 9 on one side of the flange ring 8 with the connecting groove 13 at one end of the water pipe 7. Then, the operator pushes the flange ring 8 slowly towards the water pipe 7. During this process, the fixing post 9 gradually penetrates into the connecting groove 13. Due to the compression of the outer wall of the fixing post 9, the fixing ring 11 is slowly pressed into the flange ring 8. When the fixing post 9 finally reaches the deepest part of the connecting groove 13, the fixing ring 11 slides into the fixing groove 10 under the strong elastic force of the spring 12. At this point, the connection between the equipment and the water pipe 7 is completed.

[0036] Reference Figure 4 and Figure 5 Each flange ring 8 has a slidingly connected sealing ring 14 on one side for sealing pipe 1, and a slidingly connected sealing ring 2 15 on one side for sealing pipe 1. Each sealing ring 2 15 has a sliding groove 16 on one side to accommodate a limiting strip 18. Multiple connecting strips 17 are fixedly connected to one side of each flange ring 8 for connecting the limiting strip 18. Each connecting strip 17 has a fixedly connected limiting strip 18 on one side to restrict the movement of sealing ring 14 and sealing ring 2 15. Each limiting strip 18 has a slidingly connected fixing pin 19 inside for fixing sealing ring 14 and sealing ring 2 15. Each pin 19 has a limiting plate 20 fixedly connected to its outer wall to limit the movement range of the pin 19. Each connecting strip 17 has a spring 21 inside to provide elastic force for the pin 19. One end of each spring 21 is fixedly connected to the inside of the connecting strip 17, and the other end of each spring 21 is fixedly connected to one end of the pin 19. The connecting strips 17 are arranged in a ring array and fixedly connected to one side of the flange ring 8. The outer wall of each pin 19 is slidably connected to the inside of the sealing ring 15. The outer wall of each limiting strip 18 is slidably connected to the inside of the sliding groove 16. The outer wall of each limiting plate 20 is slidably connected to the inside of the limiting strip 18.

[0037] Specifically, when it is necessary to replace sealing ring 14 or sealing ring 2 15, the operator first extends both hands to hold the sealing ring 14 or sealing ring 2 15 to be replaced. Then, the operator rotates the sealing ring in a clockwise direction. During the rotation, its inner wall gradually comes into close contact with the fixing pin 19. As the rotation angle increases, the squeezing force of the inner wall of the sealing ring on the fixing pin 19 also increases, forcing the fixing pin 19 to slowly retract into the limiting strip 18. With continued rotation, when the limiting strip 18 slides completely out of the sliding groove 16, the operator pulls the sealing ring 14 or sealing ring 2 15 outward. Thus, the sealing ring 14 or sealing ring 2 15 is successfully removed from the equipment, preparing for the subsequent installation of a new sealing ring.

[0038] Working principle: When using the valve structure for sewage pipelines, to connect the equipment to the water pipe 7, first align the fixing post 9 on one side of the flange ring 8 with the connecting groove 13 at one end of the water pipe 7. Then, bring the flange ring 8 and the water pipe 7 closer together, so that the fixing post 9 enters the connecting groove 13. During this process, the fixing ring 11 is squeezed into the flange ring 8 by the outer wall of the fixing post 9. When the fixing post 9 enters the deepest part of the connecting groove 13, the fixing ring 11 is ejected by the spring 12 and slides into the fixing groove 10, thus completing the connection between the equipment and the water pipe 7. Then, rotate the turntable 6 to control the valve 3. The opening and closing degree controls the liquid flow rate inside pipe 1. When it is necessary to replace sealing ring 14 or sealing ring 2 15, first hold sealing ring 14 or sealing ring 2 15 and rotate it clockwise so that its inner wall squeezes the fixing pin 19 to retract the fixing pin 19 into the limiting strip 18, thus unlocking sealing ring 14 or sealing ring 2 15. When the limiting strip 18 slides completely out of the sliding groove 16, pull sealing ring 14 or sealing ring 2 15 outward to remove sealing ring 14 or sealing ring 2 15. Then reinstall the new sealing ring 14 or sealing ring 2 15 to complete the replacement.

[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.
