[0004] The above patents or existing anti-leakage devices have the following problems:

[0005] Most of the existing anti-leakage devices place a sealing plate between the two pipe connections, then connect the two pipes with bolts and apply pressure to the sealing plate to seal it at the connection. The sealing effect is relatively general if the sealing plate is used alone, and misalignment may occur during the installation process. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a pipeline butt joint anti-leakage device.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pipeline docking anti-leakage device, including a sealing plate, a docking sealing structure is arranged on the sealing plate, the docking sealing structure includes a docking tube, a docking tube is arranged in the sealing plate, an inner cavity is arranged inside the docking tube and the sealing plate, and the inner cavity in the docking tube and the sealing plate is communicated, a sealing ring is arranged on the docking tube, and the inner cavity is filled with fluid.

[0008] Preferably, the sealing ring is lower than the outer surface of the butt joint tube in a natural state without being subjected to force.

[0009] Preferably, a pressure flow plate is provided in the inner cavity of the sealing plate, and the surface of the pressure flow plate is an inclined surface.

[0010] Preferably, the outer diameter of the butt joint is matched to the inner diameter of the pipeline.

[0011] Beneficial effects of the utility model:

[0012] The utility model is provided with a butt sealing structure. When installing the sealing plate, the butt pipe at one end is butt-jointed with one of the pipes. After the butt joint is complete, the sealing plate will fit on the surface of the pipe opening. After the other pipe is butt-jointed with the butt pipe, the sealing plate will be cushioned at the butt joint of the two pipes to realize convenient installation of the sealing plate. When the two pipes are fixed by bolts, the sealing plate will be squeezed to be compressed and filled between the two pipes. At the same time, the fluid in the inner cavity will be pushed into the butt pipe and push the sealing ring so that the sealing ring is tightly against the inner wall of the pipe. The tighter the two pipes are connected and fixed, the tighter the sealing ring will fit on the inner wall of the pipe, thereby improving the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0018] See also Figure 1 and Figure 2 The utility model provides a pipeline butt joint anti-leakage device, including a sealing plate 1, which is padded between the connection of two pipelines, and then the two pipelines are fixed by bolts, so that the two pipelines squeeze the sealing plate 1. At this time, the sealing plate 1 will fill the connection of the two pipelines, thereby sealing and preventing leakage. The sealing plate 1 is made of rubber material, and a butt joint sealing structure 2 is arranged on the sealing plate 1.

[0019] See also Figure 2 and Figure 3 The utility model provides a pipeline docking anti-leakage device, the docking sealing structure 2 includes a docking pipe 21, the inner circle of the sealing plate 1 is integrally formed with the docking pipe 21, the outer diameter of the docking pipe 21 is adapted to the pipeline, so as to facilitate docking installation, ensure the placement and installation of the sealing plate 1, effectively avoid the position deviation of the sealing plate 1, and the phenomenon of skewed installation. The sealing plate 1 and the docking pipe 21 are both provided with an inner cavity 22, and the inner cavity 22 in the docking pipe 21 and the sealing plate 1 are communicated, and a pressure flow plate 25 is integrally formed in the inner cavity 22 of the sealing plate 1, and the surface of the pressure flow plate 25 is inclined. The surface can push the pressure plate 25 when the sealing plate 1 is under pressure, and push the fluid 24 filled in the inner cavity 22 downward to avoid the phenomenon that the fluid 24 is blocked. A sealing ring 23 is arranged on the butt joint pipe 21. The fluid 24 filled in the inner cavity 22 will contact the inner surface of the sealing ring 23, and when the sealing ring 23 is in a natural state of force, the outer surface of the sealing ring 23 is lower than the outer surface of the butt joint pipe 21, so that when the butt joint pipe 21 is butt jointed in the pipeline, the friction between the sealing ring 23 and the inner wall of the pipeline can be avoided to cause the butt joint resistance. The fluid 24 is a liquid sealant.

[0020] When installing the sealing plate 1, connect the butt joint 21 at one end to one of the pipes. After complete connection, the sealing plate 1 will fit on the surface of the pipe mouth. After the other pipe is connected to the butt joint 21, the sealing plate 1 will be placed at the butt joint of the two pipes to achieve convenient installation of the sealing plate 1. When the two pipes are fixed by bolts, the sealing plate 1 will be squeezed to compress it and fill it between the two pipes. At the same time, the fluid 24 in the inner cavity 22 will be pushed into the butt joint 21 and push the sealing ring 23, so that the sealing ring 23 is tightly against the inner wall of the pipe. The tighter the two pipes are connected and fixed, the tighter the sealing ring 23 fits against the inner wall of the pipe, thereby improving the sealing effect.
