Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection anti-leakage, and specifically to an anti-leakage structure for a water delivery pipeline. Background Art

[0002] Due to reasons such as careless pipeline construction and poor material quality, water supply pipelines often leak during use, which has a serious impact on the building structure and project progress. Leakage problems will not only cause moisture and damage to the walls, floors and other parts of the house inside and outside, but may also cause damage to indoor equipment, decoration, and even safety hazards to electrical facilities. Therefore, anti-leakage construction technology for water supply pipelines is particularly important in the project.

[0003] The patent specification with application number 202020078305.5 discloses an anti-leakage structure for a water supply pipeline, which relates to a pipeline connection structure, aiming to solve the problem in the prior art that the pipeline connection is prone to gaps due to the different foundation heights in different areas, causing the water in the pipeline to leak out of the pipeline; its main technical solution includes a connector arranged on the outer wall of the pipeline and used to connect adjacent pipelines, a seal arranged between adjacent pipelines and used to close the gap between the end walls of adjacent pipelines, and an extrusion arranged on the inner wall of the pipeline and used to increase the extrusion force between the seal and the end face of the pipeline; the connector connects the adjacent pipelines, and when water flows in the pipeline, the water pushes the extrusion, and the extrusion pushes the seal, and the seal and the end face of the pipeline are pressed against each other, reducing the possibility of a gap between the adjacent end faces of the two pipes, thereby improving the sealing of the pipeline connection, which is beneficial to reducing the possibility of water leakage through the pipeline connection.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned anti-leakage structure for water pipelines has the following problems: when the water pressure is relatively large, the extrusion parts on the inner wall of the pipeline may affect the water flow, thereby affecting the progress of water delivery, and may also generate other forces on the connection, reducing the service life and increasing the possibility of pipeline leakage. The anti-leakage effect is not good. For this reason, we propose an anti-leakage structure for water pipelines. Utility Model Content

[0005] The utility model provides an anti-leakage structure for a water delivery pipeline, which solves the problem in the related art that the anti-leakage effect is poor due to the high water pressure and structure of the water delivery pipeline.

[0006] The technical solution of the utility model is as follows:

[0007] A leakage-proof structure for a water pipeline comprises an inlet pipe, characterized in that a water joint is sleeved on the outer surface of the inlet pipe, a first annular groove is provided on the surface of the water joint, an arc-shaped groove is provided on the inner wall of the water joint, a water outlet pipe is provided on the top of the inlet pipe, a water outlet pipe is sleeved on the outer surface of the outlet pipe, a second annular groove is provided on the outer surface of the water outlet joint, a fixed block is fixedly connected to the outer surface of the water outlet joint, and a J-shaped rod is inserted and connected inside the fixed block.

[0008] Preferably, a first gasket is embedded in the interior of the first annular groove, and the first gasket is made of rubber.

[0009] Preferably, an extrusion plate is embedded inside the arc-shaped groove, a threaded rod is fixedly connected to the top of the extrusion plate, and a butterfly nut is threadedly connected to the outer surface of the threaded rod.

[0010] Preferably, a second gasket is embedded in the interior of the second annular groove, and the second gasket is made of polypropylene.

[0011] Preferably, a second positioning block is fixedly connected to the interior of the first annular groove, and the number of the second positioning blocks is two, and the positions are the same as those of the first positioning blocks.

[0012] Preferably, the outer surface of the water inlet pipe is movably connected to a support seat, and the top end of the support seat is rotatably connected to a clamping block.

[0013] Preferably, the support seat and the clamping block are movably connected by a hinge on one side and are inserted and connected by bolts on the other side, and a hexagonal nut is threadedly connected to the outer side of the bolt.

[0014] Preferably, a groove is provided inside the support seat, a waterproof cloth is provided inside the groove, and a sandbag layer is laid on the waterproof cloth.

[0015] The working principle and beneficial effects of the utility model are:

[0016] In the utility model, after the water supply joint and the water outlet joint are embedded and matched with each other, the butterfly nut is tightened to make the outer side of the water supply joint and the inner wall of the first annular groove of the water outlet joint fit tightly, and the J-shaped rod is rotated to make its bottom fit with the bottom surface of the upper part of the water supply joint, and the hexagonal nut is tightened to complete the installation.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0025] like Figure 1~Figure 5 As shown, the present embodiment proposes that the outer surface of the water inlet pipe 1 is sleeved with a water delivery joint 2, the surface of the water delivery joint 2 is provided with a first annular groove 3, the inner wall of the water delivery joint 2 is provided with an arc groove 5, the outer surface of the water delivery joint 2 is provided with a square groove, and the inside of the square groove is fixedly connected with a first positioning block 9, and one end of the first positioning block 9 is a semicircular groove, and the radius is the same as the radius of the threaded rod 7, the top of the water inlet pipe 1 is provided with a water outlet pipe 10, and the top of the water inlet pipe 1 and the top of the water outlet pipe 10 are fitted, the outer surface of the water outlet pipe 10 is sleeved with a water outlet joint 11, the outer surface of the water outlet joint 11 is provided with a second annular groove 12, and the upper outer surface of the water outlet joint 11 is fixedly connected with a fixing block 15, the inside of the fixing block 15 is provided with a through hole, and the inside of the fixing block 15 is connected with a J-shaped rod 16 through the through hole.

[0026] In this embodiment, a first gasket 4 is embedded in the first annular groove 3, and the first gasket 4 is made of rubber material, which increases the airtightness of the connection and helps prevent water leakage.

[0027] In this embodiment, an extrusion plate 6 is embedded inside the arc groove 5 to save space and reduce the impact on the water flow. A threaded rod 7 is fixedly connected to the top of the extrusion plate 6, and a butterfly nut 8 is threadedly connected to the outer surface of the threaded rod 7, which saves the user more effort.

[0028] In this embodiment, a second gasket 13 is embedded in the interior of the second annular groove 12 , and the second gasket 13 is made of polypropylene, which has good environmental performance, low price, and saves cost.

[0029] In this embodiment, a second positioning block 14 is fixedly connected to the inside of the first annular groove 3, and there are two second positioning blocks 14, which are located at the same position as the first positioning block 9. After the first positioning block 9 and the second positioning block 14 are fitted together, insertion space is left for the threaded rod 7 to save space. Example 2

[0030] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the outer surface of the water inlet pipe 1 is movably connected with a support seat 18, the top end of the support seat 18 is rotatably connected with a block 19, and the top surface of the support column 18 and the bottom surface of the block 19 are fitted together.

[0031] In this embodiment, the support seat 18 and the clamping block 19 are movably connected on one side by a hinge 23, and are connected on the other side by a bolt 20. The outer side of the bolt 20 is threadedly connected with a hexagonal nut 17 to make the connection more stable and prevent the pipeline from displacement.

[0032] In this embodiment, a groove is opened inside the support seat 18, and a waterproof cloth 21 is provided inside the groove to prevent the leaked water from damaging the support seat 18. A sandbag layer 22 is laid on the waterproof cloth 21 to help absorb water from the leak.

[0033] Working principle: Before installing the pipeline, the staff first sets the water supply joint 2 on the outer surface of one end of the water inlet pipe 1, and sets the water outlet joint 11 on the outer surface of one end of the water outlet pipe 10, and fixes them with epoxy resin glue. The first positioning block 9 fixedly connected to the water supply joint 2 and the second positioning block 14 fixedly connected to the water outlet joint 11 are mutually positioned and matched, and the water supply joint 2 is inserted into the water outlet joint 11, so that one end of the water supply joint 2 and the second gasket 13 are tightly fitted. At this time, the second gasket 13 is embedded in the bottom surface of the second annular groove 12, and the J-shaped rod 16 inserted into the fixing block 15 is rotated to make the bottom of the J-shaped rod 16 fit with the upper bottom surface of the water supply joint 2, and the hexagonal nut 17 is tightened, and the butterfly nut 8 is rotated to make the butterfly nut 8 The threaded rod 7 is spirally rotated downward to drive the extrusion plate 6 in the arc groove 5, so that the extrusion plate 6 squeezes the first gasket 4 embedded in the first annular groove 3, so that the outer surfaces of the first gasket 4 and the water delivery joint 2 are tightly fitted against the inner wall of the second annular groove 12, and the clamping is completed. In this way, the problem of leakage when the water pressure is relatively large can be solved. Then, the support seat 18 and the block 19 are respectively connected to the outer surfaces of the water inlet pipe 1 and the water outlet pipe 10, and the bolts 20 are tightened to support the pipeline to reduce the force, so that the probability of leakage of the structure is reduced, and the waterproof cloth 21 and the sandbag layer 22 are installed in the groove on the upper surface of the support seat 18 at one time. If leakage unfortunately occurs, the sandbag layer 22 can absorb water, and the waterproof cloth 21 can block water, thereby reducing the loss caused by leakage.

[0034] The above are only preferred embodiments of the present invention and are 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 in the protection scope of the present invention.
