Description

Technical Field

[0001] This invention belongs to the field of water supply and drainage pipeline construction technology, and in particular relates to a municipal water supply and drainage pipeline joint. Background Technology

[0002] Water supply and drainage, also known as water supply and drainage engineering, refers to engineering projects involving water supply, wastewater discharge, and water quality improvement. It utilizes a wide variety of pipes, including corrugated pipes. During construction, pipe joints are used to connect and install two pipes together. However, most existing pipe joints are of fixed length, making it impossible to adjust the overall length to suit specific needs. This results in frequent adjustments to the relative positions of the two pipes during connection, leading to cumbersome, time-consuming, and labor-intensive operations, and also resulting in poor sealing at the pipe joints. Therefore, it is necessary to improve existing pipe joints. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the deficiencies in the prior art and proposes a municipal water supply and drainage pipe joint.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A municipal water supply and drainage pipe joint includes a left connecting part, a right connecting part, and a connecting part between the two. The connecting part includes a corrugated pipe section with intermediate flanges at both ends and an array of spacing adjustment components between the two intermediate flanges. The left connecting part includes a left connecting section with a left connecting flange at the end of the left connecting section away from the connecting part and a left flange gasket on the outer end face of the left connecting flange. The right connecting part includes a right connecting section with a right connecting flange at the end of the right connecting section away from the connecting part and a right flange gasket on the outer end face of the right connecting flange.

[0006] Furthermore, the diameter of the left connecting segment is the same as the diameter of the right connecting segment.

[0007] Furthermore, the diameter of the left connecting segment is the same as the diameter of the right connecting segment.

[0008] Furthermore, the outer diameter of the left connecting flange is larger than that of the right connecting flange.

[0009] Furthermore, the outer diameters of the two intermediate flanges are the same.

[0010] Furthermore, the adjustment assembly includes connecting bolts that pass through the two intermediate flanges in sequence, and a locking nut is screwed onto the end of each bolt.

[0011] Furthermore, the spacing adjustment components are provided in 3-4 groups, and each spacing adjustment component is evenly distributed along the outer circumference of the corrugated pipe section.

[0012] Furthermore, the left flange gasket is made of rubber or silicone, and the right flange gasket is made of rubber or silicone.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a rationally designed structure that allows for adaptive adjustment of the pipe joint length to match the connection requirements of two pipes. This simplifies the construction process, avoids frequent adjustments to the connected pipes, and improves work efficiency. By tightening the locking nut, the distance between the two intermediate flanges is reduced, thereby shortening the corrugated pipe section. In other words, the total length of the pipe joint is reduced by decreasing the length of the connection portion. Conversely, the total length of the pipe joint is increased by increasing the length of the connection portion. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A type of municipal water supply and drainage pipe joint, such as Figures 1 to 5 As shown, the joint includes a left connecting portion 1, a right connecting portion 2, and a connecting portion 3 between them. The connecting portion includes a corrugated pipe section 4, with intermediate flanges 5 at both ends of the corrugated pipe section. An array of spacing adjustment components is provided between the two intermediate flanges. The two intermediate flanges have the same outer diameter. For example, 3-4 sets of spacing adjustment components are provided, evenly distributed along the outer circumference of the corrugated pipe section. To improve the structural stability of this pipe joint, in an optional embodiment, such as... Figure 2 and Figure 3 As shown, several guide posts 8 can be set on one of the intermediate flanges, and guide holes are provided on the other intermediate flange to correspond to the guide posts. That is, the guide posts on one of the intermediate flanges slide with the through holes on the other intermediate flange, which can further improve the structural strength and structural stability of the connection part.

[0026] This pipe fitting can be used for connecting pipes of equal diameter. In this case, the diameter of the left connecting section is the same as the diameter of the right connecting section. This pipe fitting can also be used for connecting pipes of unequal diameter. In this case, the diameter of the left connecting section is greater than the diameter of the right connecting section by the same value. In this configuration, the outer diameter of the left connecting flange is larger than that of the right connecting flange. The left connecting portion includes a left connecting section 9, with a left connecting flange 10 at the end furthest from the connecting part, and a left flange gasket 11 on the outer end face of the left connecting flange. The right connecting portion includes a right connecting section 12, with a right connecting flange 13 at the end furthest from the connecting part, and a right flange gasket 14 on the outer end face of the right connecting flange.

[0027] Typically, the adjustment assembly includes connecting bolts 6 sequentially inserted into the two intermediate flanges, with locking nuts 7 screwed onto the ends of the bolts. A 5-10mm gap is maintained between the bellows section and the connecting bolts to prevent interference between the bellows section and the connecting bolts during contraction or elongation. The left flange gasket is made of rubber or silicone, and the right flange gasket is also made of rubber or silicone.

[0028] In application, the length of this pipe joint can be adaptively adjusted as needed to match the connection requirements of two pipes, simplifying the construction process, avoiding frequent adjustments to the connected pipes, and improving work efficiency. Specifically, by tightening the locking nut, the distance between the two intermediate flanges is reduced, thereby shortening the corrugated pipe section, that is, reducing the total length of the pipe joint by reducing the length of the connection portion. Conversely, by loosening the locking nut, the distance between the two intermediate flanges is increased, which allows the corrugated pipe section to grow longer, thereby increasing the total length of the pipe joint by increasing the length of the connection portion.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
