[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] See also Figures 1 to 4The utility model provides a technical solution: a fire-fighting pipe anti-seepage device, comprising two mounting rings 5 installed at the joints of two fire-fighting pipes 1, wherein the mounting rings 5 are provided with a heat preservation structure and a first sealing structure, a connecting flange 2 is fixed to the end of the fire-fighting pipe 1, the first sealing structure corresponds to the connecting flange 2, a waterproof structure is provided in the first sealing structure, the two mounting rings 5 and the two connecting flanges 2 are fixedly connected by a plurality of bolts, and a second sealing structure is provided between the two fire-fighting pipes 1.
[0023] In this embodiment, a groove 3 is provided in the fire-fighting pipe 1 , and the second sealing structure includes a sealing ring 4 , which is located in the groove 3 .
[0024] Specifically, when two fire-fighting pipes 1 are connected by the connecting flange 2, the connecting flange 2 is fixed by bolts. At this time, the fire-fighting pipe 1 squeezes the sealing ring 4, and the sealing ring 4 fills the groove 3, thereby blocking the gap between the two fire-fighting pipes 1. In addition, the sealing ring 4 has a certain elasticity, which can compensate for the thermal expansion and contraction of the fire-fighting pipe 1 and the connecting flange 2.
[0025] A connecting plate 6 is fixed to the end of the mounting ring 5 . A through hole 7 is formed in the connecting plate 6 . The through hole 7 corresponds to the bolt. A sealing gasket 8 is fixed to the connecting plate 6 .
[0026] Specifically, when the mounting ring 5 needs to be installed, the mounting ring 5 is connected through the connecting plate 6. The mounting ring 5 is a semi-annular structure. Two mounting rings 5 are combined to form an annular structure, so that it can be fixed on the circumference of the fire pipe 1. Then, the connecting plate 6 is fixed together by bolts, so that the mounting ring 5 can be clamped and fixed on the circumference of the fire pipe 1.
[0027] A placement groove 9 is opened in the mounting ring 5, and the insulation structure includes an insulation board 10. The insulation board 10 is a semi-annular structure and is fixed in the placement groove 9. A cavity 11 is opened on the opposite inner side of the mounting ring 5. The connecting flange 2 is located in the cavity 11. The first sealing structure is fixed in the cavity 11. The first sealing structure includes an airbag 12, which is fixedly connected to the cavity wall of the cavity 11. The waterproof structure includes a waterproof cloth 13, which is fixedly connected to the airbag 12 and is in contact with the fire pipe 1 and the connecting flange 2.
[0028] Specifically, the insulation board 10 can achieve a good insulation effect, reduce the thermal expansion and contraction of the fire pipe 1 and the connecting flange 2, and can inflate the airbag 12 to make the airbag 12 bulge, thereby ensuring that the waterproof cloth 13 is close to the fire pipe 1 and the connecting flange 2, thereby achieving a better sealing effect.
[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
