Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a municipal road water supply and drainage pipeline connector. Background Technology

[0002] Municipal road water supply and drainage pipeline systems are an important component of urban infrastructure construction, primarily responsible for collecting, transporting, and discharging rainwater, sewage, and other liquid waste from roads. With the acceleration of urbanization, the scale and complexity of municipal road construction are constantly increasing, and the design and construction of water supply and drainage pipeline systems are facing more and more challenges. During the installation of water supply and drainage pipelines, connectors, as important components, are directly related to the sealing, stability, and long-term reliability of the pipeline system. Currently, municipal road water supply and drainage pipeline connectors mostly adopt traditional welding, threaded connections, and flange connections, but these connection methods have some problems in practical applications.

[0003] Existing water supply and drainage pipe connectors mostly fix pipes together by placing a gasket at the closest end of the two pipes and then applying pressure through the prestress of the flanges during connection to ensure a seal. However, over time, the distance between the two connecting flanges gradually increases, leading to seal failure. In addition, most existing water supply and drainage pipe connectors are installed using welding, threaded connections, or flange connections, which often require a long installation and commissioning time during construction, resulting in a long construction period and high costs.

[0004] Therefore, those skilled in the art have provided a municipal road water supply and drainage pipe connector to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a municipal road water supply and drainage pipeline connector. Through a sealing component, two sealing gaskets press against a spring ring when the two connecting flanges are fitted together, thus applying prestress to the sealing gaskets. Further prestress is applied to the sealing gaskets by the spring rings when the two connecting flanges are fitted together, effectively preventing the sealing effect from failing due to loosening at the connection point later.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A municipal road water supply and drainage pipeline connector includes two connecting pipes. Each of the two connecting pipes has a connecting assembly on one side close to each other. Each connecting assembly includes a connecting flange fixedly connected to the outer wall of the connecting pipe. The outer wall of each connecting flange has a fastening groove. The inner wall of the fastening groove on the side away from the middle of the connecting pipe has a first arc-shaped sectional surface. The lower end of each of the two connecting flanges is provided with a lower clamp. The rear end of the upper surface of the lower clamp is rotatably connected to an upper clamp. The inner walls of both the upper and lower clamps have connecting grooves. The inner walls on both sides of the connecting groove have second arc-shaped sectional surfaces. A sealing assembly is provided on the side of each of the two connecting pipes that are close to each other. The sealing assembly includes a receiving groove opened on the outer wall of the side of the two connecting pipes that are close to each other. Multiple spring rings are fixedly connected to the inner wall of the receiving groove on the side of the connecting pipe that is close to the middle of the connecting pipe. A sealing gasket is fixedly connected to the side of the spring ring that is away from the middle of the connecting pipe. The above technical solution, through the cooperation of the connection components and sealing components, can quickly connect water supply and drainage pipes while effectively improving sealing performance.

[0007] Furthermore, the front end of the outer wall of the upper clamp is rotatably connected with a bolt, and the front end of the outer wall of the lower clamp is provided with a threaded hole, and the bolts are all threadedly connected to the inner wall of the threaded hole. The above technical solution effectively fixes the upper and lower clamps by setting bolts and threaded holes.

[0008] Furthermore, the outer walls of the two sealing gaskets are tightly fitted together on their adjacent sides, and the outer walls of both sealing gaskets are tightly fitted together with the inner wall of the receiving groove. The above technical solution can effectively improve the sealing performance of the connector during connection.

[0009] Furthermore, the first arc-shaped cut surface is in close contact with the second arc-shaped cut surface; Through the above technical solution, while the two connecting flanges are fastened by the upper and lower clamps, the two connecting pipes can be effectively pulled closer by the first and second arc-shaped cut surfaces.

[0010] Furthermore, the inner walls on both sides of the connecting groove are tightly fitted to the inner wall of the fastening groove on the side away from the middle of the connecting pipe; The above technical solution allows for the rapid fastening of two connecting flanges together.

[0011] Furthermore, threaded grooves are provided on the inner wall of both connecting pipes on the side away from the connecting flange; The above technical solution allows for easier threaded connection between the water supply and drainage pipes, the outer wall threads, and the gaskets, through the provided threaded grooves.

[0012] This utility model has the following beneficial effects: 1. The present invention proposes a municipal road water supply and drainage pipeline connector. Through the setting of the sealing component, the two sealing gaskets squeeze the spring ring against each other when the two connecting flanges are attached, so that the spring ring applies a certain prestress to the sealing gasket. Then, when the two connecting flanges are attached, the spring ring applies pressure to the sealing gasket again to apply prestress, thereby effectively preventing the problem of sealing failure due to loosening of the connection in the later stage.

[0013] 2. The municipal road water supply and drainage pipeline connector proposed in this utility model, through the setting of the connecting components, involves fitting two connecting flanges together, then sleeve the upper and lower clamps on the outside of the two connecting flanges, and then fitting the first arc-shaped sectional surface and the second arc-shaped sectional surface together. Thus, when the upper and lower clamps are closed, the two connecting flanges are fitted together through the first and second arc-shaped sectional surfaces, thereby effectively bringing the positions of the two connecting flanges closer together.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] One specific embodiment of this utility model is provided: Reference Figures 1-5 : A municipal road water supply and drainage pipeline connector includes two connecting pipes 1. Each connecting pipe 1 has a connecting component 3 on one side close to the other. Each connecting component 3 includes a connecting flange 301 fixedly connected to the outer wall of the connecting pipe 1. Each connecting flange 301 has a fastening groove 302 on its outer wall. Each fastening groove 302 has a first arc-shaped sectional surface 303 on its inner wall away from the middle of the connecting pipe 1. Each connecting flange 301 has a lower clamp 305 at its lower end. Each lower clamp 305 has an upper clamp 304 rotatably connected to the rear end of its upper surface. Each upper clamp 304 and lower clamp 305 has a connecting groove 306 on its inner wall. Each connecting groove 306 has a second arc-shaped sectional surface 307 on both sides of its inner wall. A sealing component 4 is provided on the side of the two connecting pipes 1 that are close to each other. The sealing component 4 includes a receiving groove 402 opened on the outer wall of the side of the two connecting pipes 1 that are close to each other. Multiple spring rings 403 are fixedly connected to the inner wall of the receiving groove 402 on the side close to the middle of the connecting pipe 1. A sealing gasket 401 is fixedly connected to the side of the spring ring 403 away from the middle of the connecting pipe 1. By using the connection component 3 and the sealing component 4 in conjunction with each other, the water supply and drainage pipes can be quickly connected while effectively improving the sealing performance.

[0018] The front end of the outer wall of the upper clamp 304 is rotatably connected with a bolt 309, and the front end of the outer wall of the lower clamp 305 is provided with a threaded hole 308. The bolts 309 are threaded into the inner wall of the threaded holes 308. By setting the bolts 309 and the threaded holes 308, the upper clamp 304 and the lower clamp 305 can be effectively fixed. The outer walls of the two sealing gaskets 401 are tightly fitted on their adjacent sides, and the outer walls of both sealing gaskets 401 are tightly fitted into the inner wall of the receiving groove 402, thereby effectively improving the sealing performance of the connector. The first arc-shaped cut surface 303 is tightly fitted into the second arc-shaped cut surface 307, thereby... While the two connecting flanges 301 are fastened by the upper clamp 304 and the lower clamp 305, the two connecting pipes 1 can be effectively pulled closer by the first arc-shaped cut surface 303 and the second arc-shaped cut surface 307. The inner walls on both sides of the connecting groove 306 are tightly fitted with the inner wall of the fastening groove 302 away from the middle of the connecting pipe 1, so that the two connecting flanges 301 can be fastened to each other quickly. The inner wall of the two connecting pipes 1 away from the connecting flanges 301 is provided with threaded grooves 2. The threaded grooves 2 make it easier for the water supply and drainage pipes to be threadedly connected to the connecting pipe 1 by matching the threads on the outer wall and the gasket.

[0019] Working principle: In use, the pipes are connected to the connecting pipe 1 through the threaded groove 2, and then the two connecting flanges 301 are aligned. The upper clamp 304 and the lower clamp 305 are then fitted onto the outside of the connecting flanges 301. One end of the upper clamp 304 and the lower clamp 305 is gradually closed, so that the first arc-shaped cut surface 303 and the second arc-shaped cut surface 307 fit together. The gradual closing of one end of the upper clamp 304 and the lower clamp 305 causes the two connecting flanges 301 to move closer together. When they move closer, the two sealing gaskets 401 are squeezed together, which in turn squeezes the spring ring 403. This provides a double prestress effect on the sealing gaskets 401 through the connecting flanges 301 and the spring ring 403, thereby improving the sealing performance. After the upper clamp 304 and the lower clamp 305 are fully closed, the two connecting flanges 301 are tightly fitted together. Finally, the bolts 309 are screwed into the threaded holes 308 to fix them.
