Description

Technical Field

[0001] This utility model relates to the technical field of water supply and drainage pre-embedded devices, specifically to a pre-embedded component for municipal water supply and drainage pipes. Background Technology

[0002] In municipal water supply and drainage engineering, embedded parts are key pipe fittings pre-embedded inside walls to allow pipes to pass through them. Their performance directly affects the stability and sealing of the water supply and drainage system. However, traditional embedded parts for municipal water supply and drainage pipes have many shortcomings: in terms of connection stability, they are not tightly bonded to the wall, and are prone to loosening and displacement after long-term use; in terms of anti-slip and anti-detachment, they lack effective anti-slip structures, and the pipes are prone to sliding under stress; the sealing performance is also poor, and water seepage is easy to occur at the connection, leading to wall damage, pipe corrosion, and affecting the normal operation and service life of the water supply and drainage system. Utility Model Content

[0003] (I) Technical Issues

[0004] This utility model addresses the problems of unstable connection, poor anti-slip and anti-detachment effect, and poor sealing of traditional municipal water supply and drainage embedded parts by providing a embedded part with a firm connection and excellent anti-slip and sealing performance.

[0005] (II) Technical Content

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a pre-embedded component for municipal water supply and drainage pipes, including a main sleeve, which is pre-embedded and fixed in the wall and extends out of the wall at both ends. An annular positioning flange is fixedly provided on both the inner and outer sides of the main sleeve near the wall. A sealing component is provided on the side of the annular positioning flange that contacts the wall. The sealing component consists of an annular sealing groove provided on the side of the annular positioning flange and an elastic rubber ring embedded in the groove. An anti-corrosion layer is coated on the inner and outer surfaces of the main sleeve and the surface of the annular positioning flange. An anti-slip component is fixedly provided on the surface of the main sleeve at the part embedded in the wall, and the anti-slip component consists of multiple toothed rings with triangular cross-sections.

[0007] Furthermore, the annular positioning flange is coaxially welded to the outer wall of the main sleeve, and its outer diameter is 1-2 times larger than the diameter of the main sleeve.

[0008] Furthermore, the annular sealing groove has a dovetail-shaped structure, and the elastic rubber ring is made of EPDM rubber.

[0009] Furthermore, the anti-corrosion layer is an epoxy asphalt composite coating, with an inner layer of epoxy primer and an outer layer of asphalt topcoat.

[0010] Furthermore, both ends of the main sleeve are fixedly provided with connecting flanges for connecting water supply and drainage pipes.

[0011] Furthermore, the plurality of toothed rings are divided into left and right groups, and the left and right groups of toothed rings are distributed in a mirror image.

[0012] (III) Technical Effects

[0013] Compared with existing technologies, the advantages of this invention are as follows: the annular positioning flange is coaxially welded to the main sleeve and has a larger outer diameter, increasing the contact area with the wall. Combined with the sealing components on the side of the annular positioning flange, it can effectively prevent the embedded parts from loosening in the wall. The part of the main sleeve embedded in the wall is equipped with an anti-slip component composed of multiple triangular toothed rings. The two sets of toothed rings are mirror-distributed on the left and right sides, which can effectively increase the friction with the wall and prevent the pipe from sliding or falling off under stress. The dovetail-shaped annular sealing groove on the side of the annular positioning flange that contacts the wall, together with the EPDM rubber elastic ring embedded therein, forms a tight sealing structure, which can effectively prevent water leakage and avoid wall dampness and pipe corrosion.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 To be continued Figure 5 An embedded component for municipal water supply and drainage pipes includes a main sleeve 1, which is embedded and fixed in a wall with both ends extending out of the wall. Connecting flanges 6 for connecting water supply and drainage pipes are fixed at both ends of the main sleeve 1. Annular positioning flanges 2 are fixed on the inner and outer sides of the main sleeve 1, near the wall. A sealing component 3 is provided on the side of the annular positioning flange 2 that contacts the wall. The sealing component 3 consists of an annular sealing groove 31 on the side of the annular positioning flange 2 and an elastic rubber ring 32 embedded in the groove. An anti-corrosion layer is coated on the inner and outer surfaces of the main sleeve 1 and the surface of the annular positioning flange 2. An anti-slip component 5 is fixed on the surface of the main sleeve 1 at the portion embedded in the wall. The anti-slip component 5 consists of multiple toothed rings 51 with triangular cross-sections, divided into left and right groups, with the left and right groups of toothed rings 51 distributed in a mirror image.

[0024] The annular positioning flange 2 is coaxially welded to the outer wall of the main sleeve 1, and its outer diameter is 1-2 times larger than the diameter of the main sleeve. The annular sealing groove 31 has a dovetail structure, and the elastic rubber ring 32 is made of EPDM rubber. The anti-corrosion layer 4 is an epoxy asphalt composite coating, with an inner layer of epoxy primer and an outer layer of asphalt topcoat.

[0025] The working principle of this utility model is as follows: This device provides a channel for water supply and drainage pipes to pass through the wall through the main sleeve 1. It uses an annular positioning flange 2 to fix the pipes to the wall (using expansion bolts) and combines this with a sealing component 3 to achieve a seal and prevent water leakage. An anti-slip component 5 increases friction with the wall, preventing the embedded parts from sliding within the wall. A connecting flange 6 connects the water supply and drainage pipes, ensuring a stable pipe connection. The anti-corrosion layer 4 protects the embedded parts from external environmental corrosion, extending their service life. All components work together to achieve the functions of stable, sealed, and durable embedded parts.

[0026] The working process of this utility model is as follows:

[0027] 1. Installation of Embedded Parts: During wall construction, the main sleeve 1 is embedded in the predetermined position in the wall, so that both ends of the main sleeve 1 extend out of the wall. The annular positioning flange 2 on the main sleeve 1, near the inner and outer sides of the wall, fits against the wall surface. An elastic rubber ring 32 is pre-embedded in the dovetail-shaped annular sealing groove 31 on the side of the annular positioning flange 2. When the wall is poured or built, the elastic rubber ring 32 is squeezed and deformed, filling the gap between the annular positioning flange 2 and the wall to form a sealing structure. After the wall solidifies, the annular positioning flange 2 is fixed to the wall with bolts.

[0028] 2. Anti-slip fixing: The anti-slip component 5 embedded in the wall body of the main sleeve 1 consists of multiple toothed rings 51 with triangular cross-sections, and the left and right sets of toothed rings 51 are distributed in a mirror image. During the wall construction process, the toothed rings 51 are embedded in the wall material, increasing the friction between the main sleeve 1 and the wall, preventing the main sleeve 1 from sliding in the wall, and achieving stable fixing.

[0029] 3. Pipe connection: After the wall construction is completed, water supply and drainage pipes are installed on the connecting flanges 6 at both ends of the main sleeve 1. The water supply and drainage pipes are fastened to the connecting flanges 6 by bolts and other connectors, so that the water supply and drainage pipes and the main sleeve 1 form a complete water supply and drainage channel.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
