Description

Technical Field

[0001] This utility model relates to the field of building seepage prevention technology, and more specifically to a seepage prevention structure for water supply and drainage engineering buildings. Background Technology

[0002] In water supply and drainage engineering, the design and construction quality of building waterproofing structures directly affect the service life and safety of buildings. Waterproofing at pipe connections, in particular, has always been a key focus and challenge in building engineering due to the complex environmental factors and usage conditions involved. Traditional waterproofing measures often fail to meet long-term, high-efficiency waterproofing requirements, leading to frequent leakage problems and consequently affecting the overall performance of the building.

[0003] For example, in existing technologies, anti-seepage structures that use clamps to connect pipes first require aligning the pipes and then putting a sealing ring on the outer side of the pipe connection. However, when putting on the sealing ring, workers often need to use a lot of force to put the sealing ring on the outer side of the connection between the two pipes, and lubricant also needs to be added, making the installation quite laborious.

[0004] Therefore, it is necessary to propose a seepage-proof structure for water supply and drainage engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of laborious installation of pipeline anti-seepage structures in the prior art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A seepage-proof structure for water supply and drainage engineering includes an annular plate. A first arc-shaped groove is formed on the inner side of the annular plate. A partition is fixedly connected to the middle of the inner side of the annular plate. An annular ring is fixedly connected to the inner side of the partition. A second arc-shaped groove is formed on the side of the annular ring facing the inner side of the annular plate. A space for installing a first annular sealing ring is formed between the second arc-shaped groove and the first arc-shaped groove.

[0008] The water supply and drainage pipe has a flange fixedly connected to its end. The flange has a through hole for annular ring insertion at the end away from the water supply and drainage pipe. A locking mechanism is provided on the annular plate to lock the flanges on the two water supply and drainage pipes tightly against the annular plate.

[0009] Furthermore, the thickness of the annular ring is less than the thickness of the annular plate, and a second annular sealing ring is fixedly connected to the inner side of the first annular sealing ring. The second annular sealing ring is inserted into the space between the two sides of the annular plate and the flange.

[0010] Furthermore, the locking mechanism includes a plurality of first threaded rods fixedly connected to both sides of the annular plate, and the flange has through holes for inserting the first threaded rods, with a first nut threadedly connected to the end of each first threaded rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by compressing the first annular sealing ring, makes it easier to connect water supply and drainage pipes.

[0013] 2. In this utility model, the first arc-shaped groove and the second arc-shaped groove are provided to pre-install the first annular sealing ring and prevent it from falling off.

[0014] 3. This utility model, through the setting of the first annular sealing ring and the second annular sealing ring, can ensure the sealing effect at the connection between the two water supply and drainage pipes and prevent water leakage at the connection between the two water supply and drainage pipes.

[0022] 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.

[0023] Please see Figures 1 to 6 A seepage-proof structure for water supply and drainage engineering includes an annular plate 5. The inner surface of the annular plate 5 needs to be flush with the inner surface of the water supply and drainage pipe 1 to ensure that no resistance is generated when water flows through. A concave first arc-shaped groove 6 is provided on the inner surface of the annular plate 5. A partition 7 is fixedly connected to the middle of the inner surface of the annular plate 5. An annular ring 8 is fixedly connected to the inner surface of the partition 7. A concave second arc-shaped groove 9 is provided on the side of the annular ring 8 facing the inner surface of the annular plate 5. A space for installing a first annular sealing ring 10 is formed between the second arc-shaped groove 9 and the first arc-shaped groove 6, which can prevent the first annular sealing ring 10 from falling off. When installing the first annular sealing ring 10, the matching tools in the prior art can also be used for installation. The specific installation method can refer to the tire installation method in the prior art.

[0024] A water supply and drainage pipe 1 is fixedly connected to a flange 2 at one end. The flange 2, away from the water supply and drainage pipe 1, has a through hole 4 for inserting an annular ring 8. A locking mechanism is provided on the annular plate 5 to lock the flanges 2 on the two water supply and drainage pipes 1 tightly against the annular plate 5.

[0025] Specifically, the thickness of the annular ring 8 is less than the thickness of the annular plate 5, meaning that there is a certain distance between both sides of the annular ring 8 and the flange 2. The inner side of the first annular sealing ring 10 is fixedly connected to the second annular sealing ring 11. The cross-section of the first annular sealing ring 10 is semi-circular. The second annular sealing ring 11 is inserted into the space between the two sides of the annular plate 5 and the flange 2, so that the second annular sealing ring 11 is squeezed between the annular ring 8 and the flange 2, further ensuring the sealing effect and preventing water from seeping from the connection of the water supply and drainage pipe 1.

[0026] Specifically, the locking mechanism includes multiple first threaded rods 12 fixedly connected to both sides of the annular plate 5. The flange 2 has through holes 4 for inserting the first threaded rods 12. The ends of the first threaded rods 12 are threaded with first nuts 16. The two water supply and drainage pipes 1 are locked by tightening the first nuts 16 onto the first threaded rods 12.

[0027] Installation method: First, install the first annular sealing ring 10 between the first arc groove 6 and the second arc groove 9. Then, align the first threaded rod 12 with the through hole 4 of the water supply and drainage pipe 1 on one side and insert it. At the same time, the first annular sealing ring 10 will enter the inner groove 3. Then, screw the first nut 16 on the end of the first threaded rod 12. As the first nut 16 is tightened, it will drive the annular plate 5 to compress the first annular sealing ring 10 and the second annular sealing ring 11 until the annular plate 5 and the flange 2 are in contact. Then, align the through hole 4 of the other water supply and drainage pipe 1 with the first threaded rod 12 on the other side of the annular plate 5 and insert it. After insertion, continue to screw the first nut 16 onto the first threaded rod 12 until the annular plate 5 and the flange 2 are in contact, and the locking is completed.

[0028] In addition, the following method can be used to lock the two water supply and drainage pipes 1, which can effectively avoid the inconvenience of disassembly during later maintenance caused by the long-term tightening of the first nut 16, and at the same time, it can also avoid the problem of the flange 2 being deformed by the rebound force of the first annular sealing ring 10 due to the tightening of the first nut 16.

[0029] Specifically, the locking mechanism includes a second threaded rod 13 fixedly connected to the outer side of the annular plate 5, an n-shaped plate 14 inserted into the second threaded rod 13, and a second nut 15 threadedly connected to the second threaded rod 13. The distance between the two ends of the n-shaped plate 14 is equal to the thickness of the two flanges 2 plus the thickness of the annular plate 5, thereby ensuring that the n-shaped plate 14 can lock the two water supply and drainage pipes 1. If the flanges 2 and the annular plate 5 do not fit together after locking, the corresponding n-shaped plate 14 can be replaced or designed for locking.

[0030] Specifically, multiple first threaded rods 12 are fixedly connected to both sides of the annular plate 5. The n-shaped plate 14 has slots symmetrically opened on one side facing the center of the annular plate 5. That is, the shape of the plates on both sides of the n-shaped plate 14 is also n-shaped, which is used to insert into the outside of the first threaded rods 12. The ends of the first threaded rods 12 are threadedly connected to the first nuts 16.

[0031] Installation Method: The initial steps are the same as described above. The difference is that you first need to screw the first nut 16 onto the second threaded rod 13 in the up / down or left / right direction and tighten it so that the flanges 2 of both water supply and drainage pipes 1 are in contact with the annular plate 5. Assuming you screw the first nut 16 onto the second threaded rod 13 in the up / down direction and tighten it, you need to insert the n-shaped plate 14 onto the second threaded rod 13 in the left / right direction, and simultaneously insert it onto the outer side of the first threaded rod 12. Then, screw the second nut 15 onto the second threaded rod 13 and the first threaded rod 12 respectively. At this point, the second nut 15 and the first nut 16 do not need to be tightened too much. Then, screw the first nut 16 onto the second threaded rod 13 in the up-down direction and loosen it. Then, insert the n-shaped plate 14 onto the second threaded rod 13 in the up-down direction, and simultaneously insert it onto the outside of the first threaded rod 12. Then, screw the second nut 15 and the first nut 16 onto the second threaded rod 13 and the first threaded rod 12 respectively. In this installation method, the second nut 15 and the first nut 16 do not need to be tightened too much, just enough to fit against the n-shaped plate 14, because the n-shaped plate 14 mainly constrains the flange 2 and the annular plate 5. The second nut 15 mainly constrains the up-down movement of the n-shaped plate 14, and the first nut 16 mainly constrains the deformation of the two side plates of the n-shaped plate 14.

[0032] To ensure proper fit between flange 2 and annular plate 5, it is necessary to select the first annular sealing ring 10 and the second annular sealing ring 11. The sealing rings used in this application are commonly used in the prior art and do not involve any improvement in their materials or density, but only their shapes. The manufacturer can select the first annular sealing ring 10 and the second annular sealing ring 11 based on actual experiments.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. The scope of patent protection of this utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model shall also be included within the scope of protection of this utility model.
