[0024] Reference Figure 1-4 The utility model embodiment is a water-leakage-proof connection structure for a building water supply pipeline, which includes a pipeline 1 and a leak-proof component 2. The pipeline 1 is fixedly connected with a pipeline flange 101, and the leak-proof component 2 includes a connecting flange 201. The connecting flange 201 cooperates with the pipeline flange 101. The interior of the connecting flange 201 is fixedly connected with a pipeline 206 extending therein, and the outer side surface of the pipeline 206 extending therein is fixedly connected with a limiting outer ring 203 and a limiting inner ring 202. The limiting outer ring 203 is located on the outer side of the limiting inner ring 202, and an internal sealing ring 205 is arranged between the limiting outer ring 203 and the limiting inner ring 202. There are two internal sealing rings 205, which are axially symmetrically arranged. The connecting flange 201 is provided with a receiving groove 207, and the receiving groove 207 is annular. An end face sealing ring 205 is arranged in the receiving groove 207. 04, the end face sealing ring 204 is in contact with the pipe flange 101, the radius of the end face sealing ring 204 is larger than the radius of the built-in sealing ring 205, there are two end face sealing rings 204, and they are axially symmetrically arranged, the inserted pipe 206 is located inside the pipe 1, and the built-in sealing ring 205 is in full contact with the inner wall of the pipe 1. When in use, the inserted pipe 206 is installed into the inside of the pipe 1, and the built-in sealing ring 205 forms a seal with the inner wall of the pipe 1, and then the pipe flange 101 and the connecting flange 201 are connected together using fasteners, and the pressure between the two is used to provide a second layer of sealing at the end face sealing ring 204. Due to the protection of the built-in sealing ring 205, the end face sealing ring 204 lacks the impact of water flow, thereby slowing down the aging degree of the end face sealing ring 204, thereby increasing the overall service life and being more durable to use. By setting up the leak-proof component 2, a sealing effect can be provided on the inner wall of the pipeline and the connection, thereby increasing the overall sealing performance and reducing the pressure on the end face sealing ring 204, thereby increasing the overall service life, improving the service life of the pipeline, and making it more durable to use; the set limiting outer ring 203 and limiting inner ring 202 can improve the stability of the built-in sealing ring 205.
