Description

Technical Field

[0001] The utility model belongs to the technical field of anti-seepage of network pipe connection, and particularly relates to an anti-seepage device at a network pipe connection. Background Art

[0002] A pipe network is a pipe system formed by multiple pipes according to the pipe transportation and drainage functions. Connecting different branch pipes through a transit bifurcated pipe is a pipe connection method often used in the pipe network system, such as connecting three different branch pipes through a Y-shaped three-way pipe. According to the functional requirements, the shape of the transit pipe includes not only the above-mentioned Y-shaped three-way pipe but also a cross-shaped four-way pipe, so as to connect four side pipes to the pipe network system.

[0003] During the construction of the pipeline network, especially when multiple side branch pipelines are connected to the transfer branch pipeline, flange connection is often used between the side branch pipeline and the transfer branch pipeline. The flange connection method is used to connect the transfer branch pipeline with different side branch pipelines.

[0004] Since the pipeline system is buried underground, and the transit branch pipe is connected to multiple side pipes through flanges, the fluid converges at the transit branch pipe position. Therefore, the transit branch pipe position is particularly prone to water seepage or even leakage. For example, if the flange at the pipeline connection position is loose, the flange will be rusted and not pressure-resistant. The converged fluid will collapse the flange under the action of water pressure, causing water seepage. As the water seepage continues to increase, the degree of flange corrosion increases, and the degree of flange looseness increases, the flange is easily completely collapsed, and high-pressure water is sprayed out in large quantities from the connection of the pipeline network.

[0005] However, it is difficult to deal with the buried pipe network quickly in the shortest time. Therefore, in actual use, the connection position of the pipe flange is often sealed, such as wrapping the connection position with sealing tape. However, this sealing method can only maintain a certain degree of sealing for a short time. At the connection of the loaded pipe network, if a sealing device with a long-lasting, good sealing effect and resistance to large amounts of water seepage cannot be used, the problem cannot be fundamentally solved.

[0016] The top of the rectangular assembly lower convex plate is fixedly connected with a plurality of screw rods fastened to the rectangular assembly upper convex plate, and the screw rods are threadedly connected with locking nuts.

[0017] Preferably, a plurality of arc-shaped grooves are provided on the inner side walls of the upper flange sealing cover and the lower flange sealing cover. When the upper flange sealing cover and the lower flange sealing cover are snapped onto the connecting flange, the connecting flange is snapped between the arc-shaped grooves.

[0018] Preferably, arc-shaped thread grooves are respectively provided on the side walls of the upper flange sealing cover and the lower flange sealing cover.

[0035] Example 1

[0036] like Figure 1-5 As shown, a device for preventing seepage at a mesh pipe connection includes a sealing mechanism 1 locked at the mesh pipe connection, wherein the sealing mechanism 1 includes an upper fork-shaped pipe cover 11 and a lower fork-shaped pipe cover 12 matched with the upper fork-shaped pipe cover 11.

[0037] Specifically, after the upper fork-shaped pipe cover 11 and the lower fork-shaped pipe cover 12 are closed and locked (specifically, the projection shape of the upper fork-shaped pipe cover 11 and the upper fork-shaped pipe cover 11 on the horizontal plane is a cross; the upper fork-shaped pipe cover 11 and the upper fork-shaped pipe cover 11 are provided with a cover cavity B adapted to the fork-shaped connecting pipe), the fork-shaped connecting pipe connecting different branch side pipes is locked and sealed.

[0038] Specifically, the outer ends of the upper fork-shaped pipe cover 11 and the lower fork-shaped pipe cover 12 are respectively integrally formed with an upper flange sealing cover 21 and a lower flange sealing cover 22 for sealing the flange at the network pipe connection; the longitudinal cross-section of the upper flange sealing cover 21 and the lower flange sealing cover 22 is semicircular, and the combined shape is adapted to the shape of the flange. The upper flange sealing cover 21 and the lower flange sealing cover 22 are fastened by a locking structure.

[0039] Specifically, the locking structure includes rectangular upper assembly convex plates integrally formed on both sides of the upper flange sealing cover 21, and rectangular lower assembly convex plates 23 on both sides of the lower flange sealing cover 22; the top of the rectangular lower assembly convex plate 23 is fixedly connected with a plurality of screws 24 fastened to the rectangular upper assembly convex plate, and the screws 24 are threadedly connected with locking nuts.

[0040] During the construction process, the upper fork-shaped pipe cover 11 and the lower fork-shaped pipe cover 12 are covered on the fork-shaped connecting pipe (the fork-shaped connecting pipe is a transit pipe used to connect different branch side pipes in the pipeline network into one). At this time, the lower flange sealing cover 22 is combined with the upper flange sealing cover 21 and covered on the connecting flange, that is, the flange is limited in the cover cavity of the lower flange sealing cover 22 and the upper flange sealing cover 21.

[0041] In order to improve the sealing effect, a plurality of arc-shaped grooves A are provided on the inner side wall of the upper flange sealing cover 21 and the inner side wall of the lower flange sealing cover 22. When the upper flange sealing cover 21 and the lower flange sealing cover 22 are clamped to the connecting flange, the connecting flange is clamped between the arc-shaped grooves A. In this way, the connecting flange is limited in the arc-shaped grooves A. When the flange has a tendency to collapse, the flange is not easy to collapse under the limitation of the arc-shaped grooves A. Therefore, in this way, the flange is prevented from collapsing in a large range and causing high-pressure water spray.

[0042] At the same time, in order to achieve complete sealing of the flange, a cylindrical sealing cover 3 is threadedly connected between the upper flange sealing cover 21 and the lower flange sealing cover 22. During the construction process, between the assembled connecting flanges, the cylindrical sealing cover 3 is put on the branch pipe. After the flanges are assembled, the flange cover is covered in the upper flange sealing cover 21 and the lower flange sealing cover 22 in the above manner, and the cylindrical sealing cover 3 is slid along the side of the branch pipe until it is threadedly fastened to the upper flange sealing cover 21 and the lower flange sealing cover 22. Specifically, arc-shaped thread grooves C are respectively opened on the side walls of the upper flange sealing cover 21 and the lower flange sealing cover 22. When the upper flange sealing cover 21 and the lower flange sealing cover 22 are combined and locked, the sealing sleeve is threadedly connected between the arc-shaped thread grooves C.

[0043] In the above manner, the flange is completely confined in the upper flange sealing cover 21 and the lower flange sealing cover 22, and is sealed by the extended cylindrical sealing cover 3.

[0044] In order to further reduce the penetration of water from the cylindrical sealing cover 3, the outer wall of the cylindrical sealing cover 3 is integrally formed with a sealing sleeve 31 that is connected and arranged therewith.

[0045] Specifically, a through hole is formed on the outer wall of the sealing sleeve 31, and the sealing sleeve 31 is integrally formed at the edge of the through hole. The sealing sleeve 31 is made of rubber. The sealing sleeve 31 is locked on the pipe at the network management through a clamp 32.

[0046] During operation, after the clamp 32 is locked to the sealing sleeve 31, the flange is completely sealed in the sealing structure.

[0047] Under the above measures, even if water seeps from the connection flange, it is only weak, and when the sealing sleeve 31 is locked, the water seeping from the flange is sealed in the sealing sleeve 31. When the connected flange is seriously corroded, since the flange is limited in the upper flange sealing cover 21 and the lower flange sealing cover 22, and the upper flange sealing cover 21 and the lower flange sealing cover 22 are locked on the bifurcated connection pipe through the cross-shaped upper fork-shaped pipe cover 11 and the lower fork-shaped pipe cover 12, an integrated pulling force is formed, which greatly avoids the technical defect of high-pressure water jetting when the flange is loose and the high-pressure water breaks the flange.

[0048] The upper fork-shaped pipe cover 11 , the lower fork-shaped pipe cover 12 , the upper flange sealing cover 21 and the lower flange sealing cover 22 are made of plastic.

[0049] Example 2

[0050] like Figure 1-5 As shown, this embodiment is a variation of Embodiment 1, and the upper fork-shaped pipe cover 11 and the lower fork-shaped pipe cover 12 are designed to be Y-shaped, straight-shaped, etc. with two or more branched pipe parts, and each corresponding branched pipe part has the upper flange sealing cover 21 and the lower flange sealing cover 22 structure. In this way, during the pipeline network construction process, different numbers of branch side pipes are assembled and connected as a whole, and the flanges at the connecting positions are sealed.

[0051] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
