During the installation of pipelines, the joints between pipelines are mostly sealed with rubber rings. The rubber rings are clamped between the ends of the two pipelines, so that there will be a certain gap between the two pipelines. The sealing rings are prone to aging during use, resulting in a decrease in sealing performance. At the same time, the rubber rings are subject to the long-term action of the fluid pressure inside the pipeline, which is prone to leakage, resulting in a waste of water resources.

[0017] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.
[0018] like Figure 1 and 2As shown, the pipeline sealing device for water conservancy and hydropower engineering construction includes two corresponding pipelines 1, flanges 12 are arranged at the ends of the pipelines 1, and a sealing member 2 is arranged between the ends of the two pipelines 1. The sealing member 2 has a support ring 21 corresponding to the end of the pipeline 1, and both ends of the support ring 21 are fixedly provided with an insertion tube 22 matching the inner side of the end of the pipeline 1, and the outer side of the insertion tube 22 is evenly provided with a sealing ring 23 along its axial direction. Both ends of the support ring 21 are provided with a sealing gasket 24 corresponding to the end of the pipeline 1, and the flanges 12 at the ends of the two pipelines 1 are detachably fixedly connected by a bolt and nut mechanism 3; in this embodiment, the insertion tube 22 is inserted into the inner side of the end of the pipeline 1, and the sealing ring 23 on the outer side of the insertion tube 22 contacts the inner side of the pipeline 1 to form a first sealing structure, and the two flanges 12 are pulled by the bolt and nut mechanism 3, so that the end of the pipeline 1 abuts against the sealing gasket 24 on the side of the support ring 21 to form a second sealing structure, and the sealing is tight through at least two levels of sealing, and the pressure on the external sealing gasket is dispersed, and it is not easy to leak.
[0019] In order to detect leakage in time and reduce the waste of water resources, Figure 3 As shown, a water leakage color-indicating ring assembly 4 is detachably fixedly mounted on the outer side of the seal 2. The water leakage color-indicating ring assembly 4 has a water absorption color-indicating ring 43 mounted on the outer side of the seal 2. When leakage occurs, water inside the pipe 1 leaks outward and soaks the water absorption color-indicating ring 43. The water absorption color-indicating ring 43 absorbs water and changes color. After the inspection personnel find that the water absorption color-indicating ring 43 changes color, they can determine that there is a water leakage, which is convenient for the inspection personnel to promptly discover the water leakage, promptly deal with it and reduce the waste of water resources.
[0020] A water absorption ring 42 is arranged on the inner side of the water absorption color developing ring 43, an outer clamping ring 41 is arranged on the outer side of the water absorption color developing ring 43, connecting plates 45 are arranged at both ends of the outer clamping ring 41, and the connecting plates 45 are detachably fixedly connected by a bolt and nut mechanism, and observation windows 44 are evenly opened on the outer clamping ring 41. The water absorption ring 42 can absorb leaked water when leakage occurs. After the water absorption ring 42 absorbs water, it soaks the water absorption color developing ring 43, and the water absorption color developing ring 43 changes color. The color change of the water absorption color developing ring 43 can be seen through the observation window 44 of the outer clamping ring 41, so as to facilitate timely detection of leakage.
[0021] The water absorption ring 42 is a sponge sheet, which is bonded to the inner side of the outer clamp ring 41. The water absorption ring 42 and the water absorption color development ring 43 are detachably fixed to the outer side of the sealing member 2 through the outer clamp ring 41, so as to facilitate replacement.
[0022] The water-absorbing color-developing ring 43 is a piece of paper that changes color when in contact with water, and the piece of paper that changes color when in contact with water is bonded to the inner side of the outer clamping ring 41 .
[0023] A sealing groove 11 matching with the insertion tube 22 is provided at the inner side of the end of the pipeline 1 . When the insertion tube 22 is inserted into the end of the pipeline 1 , the insertion tube 22 is just embedded into the inside of the sealing groove 11 .
[0024] Three sealing rings 23 are evenly arranged on the outer side of the insertion tube 22 along its axial direction. The sealing rings 23 are O-type sealing rings. The three sealing rings 23 further improve the sealing performance between the insertion tube 22 and the pipeline 1.
[0025] The sealing gasket 24 is a rubber sealing ring fixedly embedded in both sides of the supporting ring 21 .
[0026] The above is a preferred implementation mode of the utility model. Technical personnel in this industry should understand that the implementation mode of the utility model is not limited by the above content, and any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the utility model should be equivalent replacement methods and are included in the protection scope of the utility model.
