Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, specifically relating to a leak-proof rainwater and sewage pipe. Background Technology

[0002] During the installation of existing pipelines, splicing is usually used. To avoid gaps at the joints, a sealing ring is usually installed between the two pipelines before splicing. The sealing ring improves the sealing effect between the two pipelines, preventing rainwater and sewage from leaking out through the gaps at the joints and improving the sealing effect. However, as impurities in the sewage flow through the pipeline, the sewage comes into contact with the sealing ring, causing the sealing ring to age due to erosion from the impurities in the rainwater and sewage, thus weakening the sealing performance.

[0003] Patent application number "CN202422268720.8" discloses a leak-proof pipe, aiming to solve the problem that after prolonged contact between the sealing ring and impurities in rainwater and sewage, the sealing ring will be corroded and aged by the impurities, thus weakening its sealing performance and affecting the overall sealing effect of the pipe. The key technical points are: it includes two pipe bodies and two connecting rings. The two pipe bodies have grooves for the sliding of the connecting rings. Each connecting ring has two placement grooves on one side, with a sealing ring placed between each groove. The two connecting rings are connected by a positioning component. When one sealing ring is corroded by rainwater and sewage, the other sealing ring can prevent leakage, improving the sealing effect at the pipe body joint. Simultaneously, it can isolate most of the impurities in the rainwater and sewage, reducing contact between the other sealing ring and these impurities, and extending the service life of the other sealing ring.

[0004] The aforementioned patent extends the service life of the sealing rings by sealing the pipe with two sealing rings. However, when the sealing component is damaged, workers need to remove the original sealing component and install a new one at the pipe joint. This method of setting the sealing component makes it inconvenient for workers to replace the sealing component while disassembling the pipe and rotating the frame, resulting in reduced efficiency in replacing the sealing component.

The two component rings constituting the installation ring are respectively disposed on two adjacent pipe bodies. An installation groove is provided at the position corresponding to the joint between the installation ring and the two pipe bodies. The two sealing half-rings are installed on the installation groove by screws. The inner wall of the sealing half-ring is provided with a groove that mates with the protrusion on the end face of the pipe body. A sealing gasket is provided on the inner groove and side wall of the sealing half-ring.

[0007] Preferably, the sidewall of the mounting groove is provided with a plurality of limiting blocks, and the sidewall of the sealing semi-ring is provided with a limiting groove that cooperates with the limiting blocks.

[0022] Please see Figure 1-6 The present invention provides the following technical solution: a leak-proof rainwater and sewage pipe, including a pipe body 1, an installation ring 2, and a sealing half-ring 3. The installation ring 2 is composed of two component rings 21 fixed together by screws. Two opposing component rings 21 are slidably installed on the pipe body 1. The two component rings 21 that make up the installation ring 2 are respectively set on two adjacent pipe bodies 1. An installation groove 22 is provided at the corresponding position of the joint between the installation ring 2 and the two pipe bodies 1. The two sealing half-rings 3 are installed on the installation grooves 22 by screws. The inner wall of the sealing half-ring 3 is provided with a groove that matches the protrusion on the end face of the pipe body 1. A sealing gasket 31 is provided on the inner wall groove and the side wall of the sealing half-ring 3.

[0023] The mounting ring 2 is slidably installed on the pipe body 1. After the two pipes are joined together, the component ring 21 is pushed to both ends of the pipe body 1. The protrusions of the two component rings 21 fit together. The shape of the component rings 21 on the pipe body 1 ensures that the component rings 21 on both sides of the end where the two pipe bodies 1 are joined together can form a mounting ring 2. The two component rings 21 are installed together by screws. The two component rings 21 fixed together form a complete mounting ring 2. The mounting ring 2 has a mounting groove 22 for the user to install the sealing half ring 3. The sealing half ring 3 is semi-circular in shape. After the two sealing half rings 3 are installed in the mounting groove 22, the ring formed by the two sealing half rings 3 covers the joint of the pipe body 1, ensuring the sealing effect of the sealing half ring 3 on the joint of the pipe body 1. The sealing half ring 3 is fixed to the side wall of the protrusion of the two mounting rings 2 by screws. The two screws on the sealing half ring 3 are respectively The sealing half-ring 3, located on the two mounting rings 2, serves as a limit, ensuring the stability of the mounting ring 2 during device use. The groove on the inner wall of the sealing half-ring 3 accommodates the end face protrusion of the pipe body 1. The fit between the groove on the inner wall of the sealing half-ring 3 and the end face protrusion of the pipe body 1 also serves as a limit, preventing the sealing half-ring 3 and the mounting ring 2 from moving due to lateral forces, thus ensuring the stability of the sealing half-ring 3 after it is installed on the pipe body 1. The sealing gasket 31 on the side wall of the sealing half-ring 3 seals the gaps between the pipe body 1 and the sealing half-ring 3, as well as between the mounting ring 2 and the sealing half-ring 3, ensuring the sealing effect of the sealing half-ring 3 on the gap between the pipe body 1 and the joint. If the sealing performance of the pipe joint is affected due to damage to the seal, the user can simply remove the sealing half-ring 3 from the mounting ring 2, improving the efficiency of the user in replacing the seal at the pipe joint.

[0024] Specifically, the side wall of the installation groove 22 is provided with multiple limiting blocks 33, and the side wall of the sealing half ring 3 is provided with a limiting groove 32 that cooperates with the limiting blocks 33. The side wall of the limiting block 33 is perpendicular to the vertical symmetry plane of the pipe body 1.

[0025] The cooperation between the limiting block 33 and the limiting groove 32 plays a guiding role, ensuring the stability of the user in the process of installing the sealing half ring 3 onto the mounting groove 22. Multiple limiting blocks 33 are provided on the side wall of the mounting groove 22 to ensure the working effect of the limiting blocks 33. The side wall shape of the limiting block 33 ensures that the user can smoothly install the sealing half ring 3 onto the mounting groove 22.

[0026] Specifically, the limiting groove 32 only penetrates the inner wall of the sealing half-ring 3, and the side wall of the sealing half-ring 3 near the outer wall has a protrusion, and the side wall of the mounting ring 2 has a groove that matches the protrusion on the side wall of the sealing half-ring 3.

[0027] The positioning of the limiting groove 32 can prevent external debris and sewage from entering the mounting groove 22. The cooperation between the side wall protrusion of the sealing half ring 3 and the outer wall groove of the mounting ring 2 will cover the joint between the side walls of the sealing half ring 3 and the limiting groove 32, preventing external debris and sewage from entering the contact gap between the mounting groove 22 and the sealing half ring 3. The above structure reduces the contact between the sealing gasket 31 and the external environment during use, and reduces the impact on the service life of the sealing gasket 31.

[0028] Specifically, the thickness of the sealing gasket 31 is greater than the distance between the sealing half-ring 3 and the sidewall that contacts the sealing gasket 31.

[0029] The thickness of the sealing gasket 31 ensures that after the sealing half-ring 3 is installed on the mounting groove 22, the sealing gasket 31 is compressed. The compressed sealing gasket 31 improves the sealing effect of the sealing gasket 31 on the gap between the mounting groove 22 and the sealing half-ring 3, as well as between the sealing half-ring 3 and the pipe body 1. The compressed sealing gasket 31 also increases the friction between the sealing half-ring 3 and the pipe body 1 and the mounting groove 22, ensuring the stability of the sealing half-ring 3 during the use of the device.

[0030] Specifically, the inner wall of the sealing gasket 31 is shaped as an outwardly inclined slope.

[0031] The inner wall shape of the sealing gasket 31 serves as a guide. During the installation of the sealing half-ring 3 onto the mounting groove 22, the inclined inner wall of the sealing gasket 31 contacts the edges of the pipe body 1 and the mounting groove 22. The inclined inner wall of the sealing gasket 31 serves as a guide, ensuring that the pipe body 1 and the mounting groove 22 can smoothly compress the sealing gasket 31, ensuring that the user will not be obstructed during the installation of the sealing half-ring 3.

[0032] Specifically, the side wall of the pipe body 1 is provided with a protrusion, and the inner wall of the mounting ring 2 is provided with a groove that matches the protrusion on the side wall of the pipe body 1. The mounting groove 22 provided on the mounting ring 2 faces the left and right sides of the pipe body 1.

[0033] The protrusions on the side walls of the main pipe body 1 are located at both ends of the main pipe body 1. This ensures that after the two component rings 21 are installed together, the mounting ring 2 can be fixed by the protrusions on the side walls of the main pipe body 1 and the corresponding grooves, thus ensuring the stability of the mounting ring 2 during the use of the device. After the mounting ring 2 is fixed, the mounting groove 22 faces the left and right sides of the device. At this time, the user can remove the sealing half ring 3 from the device by moving it to the left and right sides. The user does not need to dig a deep pit to remove the sealing half ring 3 from the mounting ring 2, making it convenient for the user to replace the sealing half ring 3.

[0034] Specifically, the end face edge of the pipe body 1 is shaped as a bevel, and the inner wall of the sealing semi-ring 3 is provided with a protrusion that matches the bevel of the end face of the pipe body 1.

[0035] The fit between the beveled edge of the pipe body 1 and the inner wall protrusion of the mounting ring 2 increases the contact area between the sealing gasket 31 and the pipe body 1, further improving the sealing effect of the sealing half-ring 3 at the joint of the pipe body 1.

[0036] The working principle and usage process of this utility model are as follows: Two pipe bodies 1 are installed together, and two opposing component rings 21 are installed together by screws. The sealing half ring 3 is installed on the mounting groove 22 by the cooperation of the limiting groove 32 and the limiting block 33. The sealing half ring 3 is fixed on the mounting ring 2 by screws, thereby achieving the sealing of the connection of the pipe body 1. When the sealing effect of the sealing half ring 3 at the joint of the pipe body 1 is reduced, only the sealing half ring 3 needs to be replaced, which reduces the maintenance difficulty of the sealing components.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
