Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage joints, and in particular to a municipal water supply and drainage reducer joint that adapts to different pipe diameters. Background Technology

[0002] Water supply and drainage joints are key components that connect different pipe sections, fittings or equipment in a pipeline system. Their main function is to ensure the smooth flow of water between pipes. In municipal water supply and drainage projects, these joints are widely used in systems such as tap water transportation, sewage treatment and rainwater discharge. Their performance directly affects the stability and service life of the pipeline system.

[0003] Currently, most water supply and drainage joints are designed with fixed pipe diameters. When there are differences in the pipe diameters being connected, multiple sizes of joints are required, making it difficult to adjust and replace them. Consequently, the flexibility in connecting different pipe diameters is poor, reducing the laying speed of water supply and drainage pipelines. To address this issue, we propose a municipal water supply and drainage reducer joint that can adapt to different pipe diameters. Utility Model Content

[0004] The purpose of this utility model is to provide a municipal water supply and drainage reducer that can adapt to different pipe diameters, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A municipal water supply and drainage reducer that can adapt to different pipe diameters includes a reducer main connector, one end of which is provided with a first reducer connector, and one end of which is provided with a second reducer connector. The left end of the reducer main connector is provided with a threaded connection end, and an annular sealing seat is fixedly connected to the outer surface of the threaded connection end.

[0007] In a further embodiment, an annular sealing gasket is fixedly connected to the inner wall of the annular sealing seat, and one end of the first reducing joint is in close contact with one side of the annular sealing gasket.

[0008] In a further embodiment, the outer surface of the right end of the first reducing connector and the outer surface of the right end of the second reducing connector are both threaded, and the outer surface of the first reducing connector is provided with a hexagonal rotating protrusion.

[0009] In a further embodiment, the inner rings of the main reducing connector, the first reducing connector, and the second reducing connector are all provided with annular grooves, and each annular groove is provided with an annular sealing ring.

[0010] In a further embodiment, the outer surface of the second reducing connector has two rotating recesses, and the inner walls of both rotating recesses are provided with anti-slip stripes.

[0011] In a further embodiment, both the reducing main connector and the threaded connection end are made of ductile iron, and the outer surfaces of the reducing main connector and the threaded connection end are coated with an anti-corrosion coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model allows direct insertion into pipes of corresponding diameters via the right end of the reducing main connector. Furthermore, the right end of the first or second reducing connector allows for flexible replacement of the reducing connection components through rotation of the threaded connection end surface, achieving flexible adaptation to different pipe diameters without the need for multiple specification connectors. This makes it more flexible and convenient to connect with different pipe diameters. The annular sealing rings within the reducing main connector, the first reducing connector, and the second reducing connector can tightly fit the pipe wall, improving the sealing performance after water supply and drainage connection.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] 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.

[0022] Please see Figures 1-4 In this utility model, a municipal water supply and drainage reducer that adapts to different pipe diameters includes a reducer main connector 1, a first reducer connector 2 at one end of the reducer main connector 1, a second reducer connector 3 at one end of the first reducer connector 2, a threaded connection end 9 at the left end of the reducer main connector 1, and an annular sealing seat 4 fixedly connected to the outer surface of the threaded connection end 9. Through the right end of the reducer main connector 1, a pipe of the corresponding diameter can be directly inserted. In addition, the right end of the first reducer connector 2 or the second reducer connector 3 can flexibly replace the reducer connection component by rotating the thread on the surface of the threaded connection end 9, so as to achieve flexible adaptation to different pipe diameters.

[0023] In a further embodiment, an annular sealing gasket 5 is fixedly connected to the inner wall of the annular sealing seat 4. One end of the first reducing connector 2 is in close contact with one side of the annular sealing gasket 5. The outer surface of the right end of the first reducing connector 2 and the outer surface of the right end of the second reducing connector 3 are both threaded. The outer surface of the first reducing connector 2 is provided with a hexagonal rotating protrusion 10. Through the annular sealing gasket 5 inside the annular sealing seat 4, a seal can be formed when the first reducing connector 2 or the second reducing connector 3 is connected to the reducing main connector 1 to prevent water leakage. Through the hexagonal rotating protrusion 10, it is easy to rotate the first reducing connector 2 with a tool, which facilitates installation and disassembly.

[0024] In a further embodiment, the inner rings of the reducing main connector 1, the first reducing connector 2, and the second reducing connector 3 are all provided with annular grooves 8. Each annular groove 8 contains an annular sealing ring 7. The outer surface of the second reducing connector 3 has two rotating recesses 6, and the inner walls of the two rotating recesses 6 are provided with anti-slip stripes. The reducing main connector 1 and the threaded connection end 9 are both made of ductile iron. The outer surfaces of the reducing main connector 1 and the threaded connection end 9 are coated with an anti-corrosion coating. The annular grooves 8 in the inner rings of the reducing main connector 1, the first reducing connector 2, and the second reducing connector 3 are used to accommodate the annular sealing ring 7. After the pipe is inserted, the annular sealing ring 7 will fit tightly against the pipe wall, enhancing the sealing between the pipe and the connector. The two rotating recesses 6 and the anti-slip stripes on the inner walls facilitate the application of external force to rotate the second reducing connector 3. The reducing main connector 1 and the threaded connection end 9 are made of ductile iron, which ensures that the connector as a whole has high structural strength and pressure resistance. In addition, the first reducing connector 2 and the second reducing connector 3 are made of the same material.

[0025] The working principle of this utility model is as follows: First, the right end of the reducing main connector 1 can be inserted into a pipe of the corresponding diameter. When there is a difference in the pipe diameter, the threaded structure of the first reducing connector 2 and the second reducing connector 3 is used to rotate on the surface of the threaded connection end 9 respectively. The screwing force is adjusted by the hexagonal rotating protrusion 10 or the rotating concave hole 6 until it contacts the annular sealing gasket 5, thereby adapting to pipes of different diameters. Then, through the annular sealing ring 7 of the inner ring of the reducing main connector 1, the first reducing connector 2 and the second reducing connector 3, they will fit tightly against the pipe wall after the pipe is connected, enhancing the sealing performance.
