Technical Field

[0001] The utility model relates to the field of building fire protection pipelines, in particular to a novel anti-seepage device for building fire protection pipelines. Background Art

[0002] The building fire protection pipeline is a pipeline system used to transport water for fire fighting. Its main purpose is to quickly provide water in the event of a fire to ensure life safety and property protection. Through the main water supply pipeline, it connects the water source with various fire hydrants, sprinkler systems, etc., and then the branch line led out from the main pipeline is used to connect specific fire fighting facilities.

[0003] When connecting two sets of pipes in existing building fire protection pipelines, flanges are usually used to fix them together. In order to prevent water seepage at the connection, gaskets are placed at the connection to seal the pipe connection. Since only gaskets are placed, the sealing connection device is relatively simple, so water seepage may occur during use, which will affect use and waste water resources. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a new type of anti-seepage device for building fire protection pipelines includes a first pipe 1 and a second pipe 2. The first pipe 1 and the second pipe 2 are symmetrically distributed. A first sealing groove 7 is opened on one side of the first pipe 1, and a fixing plate 6 is fixedly connected to the inside of the first pipe 1. A second sealing groove 8 is opened on one side of the fixing plate 6; a mounting plate 3 is fixedly connected to one side of the second pipe 2, and the first sealing gasket 4, the second sealing gasket 5 and the second pipe 2 can be connected together through the provided mounting plate 3. A first sealing gasket 4 is fixedly connected to the middle part of one side of the mounting plate 3, and one end of the first sealing gasket 4 extends to the inside of the first sealing groove 7. A second sealing gasket 5 is fixedly connected to the bottom of one side of the mounting plate 3, and one end of the second sealing gasket 5 extends to the inside of the second sealing groove 8. The first sealing gasket 4 and the second sealing gasket 5 are tightly fitted with the first sealing groove 7 and the second sealing groove 8, respectively.

[0024] In this embodiment, a connecting groove 9 is left at the joint between the first pipe 1 and the second pipe 2. A gasket 10 is movably provided in the connecting groove 9. The outer ring of the gasket 10 is fixedly connected to a sealing ring 11. The inner side of the sealing ring 11 is tightly fitted with the outer walls of the first pipe 1 and the second pipe 2.

[0025] When the first pipe 1 and the second pipe 2 are spliced, the second sealing gasket 5 is driven by the mounting plate 3 to be inserted into the second sealing groove 8 opened in the fixing plate 6 to form a first sealing treatment. At the same time, the first sealing gasket 4 is inserted into the first sealing groove 7 to form a second sealing treatment. After the first pipe 1 and the second pipe 2 are docked together, the sealing ring 11 is sleeved on the docking position, and the gasket 10 is driven to be embedded in the connecting groove 9 to seal the docking position again, thereby forming three sealing treatments at the docking position of the first pipe 1 and the second pipe 2, greatly increasing the sealing performance of the docking position, preventing water seepage at the docking position, and avoiding the impact of the use of the fire protection pipeline, thereby protecting water resources and avoiding waste.

[0026] In this embodiment, the end of the first pipe 1 is fixedly connected to a first flange 12, and two groups of positioning grooves 14 are opened on the first flange 12. The two groups of positioning grooves 14 are symmetrically distributed about the central axis of the first flange 12. The end of the second pipe 2 is fixedly connected to a second flange 13, and two groups of positioning blocks 15 are fixedly connected to one side of the second flange 13, and the positioning blocks 15 are adapted to the positioning grooves 14.

[0027] When the first pipe 1 and the second pipe 2 are docked, the positioning block 15 on the first flange 12 is inserted into the positioning groove 14 to quickly dock the first pipe 1 and the second pipe 2 together. At the same time, the connecting holes on the first flange 12 and the second flange 13 can be quickly aligned, making it convenient to screw the bolt knob into the connecting hole, and then the nut is used to firmly connect the first flange 12 and the second flange 13 together, thereby fixing the first pipe 1 and the second pipe 2 together.

[0028] In this embodiment, a mounting plate 16 is fixedly connected to the outer wall of the first pipe 1, and two groups of mounting plates 16 are symmetrically distributed. A slot is provided on one side of the mounting plate 16, and one end of the positioning block 15 extends into the slot. A positioning rod 17 is movably provided on the mounting plate 16, and one end of the positioning rod 17 is fixedly connected to a pull plate 20. A positioning hole 19 is provided on the positioning block 15, and one end of the positioning rod 17 extends into the positioning hole 19.

[0029] After the positioning block 15 passes through the positioning groove 14 and is inserted into the slot, the positioning rod 17 is pressed by the pull plate 20 and inserted into the positioning hole 19 to fix the position of the positioning block 15 to prevent the positioning block 15 from falling off from the positioning groove 14, thereby completing the preliminary fixation of the first flange 12 and the second flange 13, thereby facilitating the subsequent tightening of the bolts and facilitating the operation of the construction personnel, thereby increasing the convenience of equipment installation.

[0030] In this embodiment, a spring 18 is sleeved on the positioning rod 17 , one end of the spring 18 is fixedly connected to one side of the pull plate 20 , and the other end of the spring 18 is fixedly connected to one side of the mounting plate 16 .

[0031] After the positioning rod 17 is inserted into the positioning hole 19, the spring 18 cooperates with the pull plate 20 to apply pressure to the positioning rod 17, fixing the positioning rod 17 in the positioning hole 19 to prevent the positioning rod 17 from falling off. At the same time, the pull plate 20 can easily pull the positioning rod 17 out of the positioning hole 19.

[0032] It should be noted that the utility model is a new type of anti-seepage device for building fire protection pipelines. When the first pipe 1 and the second pipe 2 are spliced, the second sealing gasket 5 is driven by the installation plate 3 to be inserted into the second sealing groove 8 opened by the fixing plate 6 to form a first sealing treatment. At the same time, the first sealing gasket 4 is inserted into the first sealing groove 7 to form a second sealing treatment. After the first pipe 1 and the second pipe 2 are docked together, the sealing ring 11 is put on the docking point, and at the same time, the gasket 10 is driven to be embedded in the connecting groove 9 to seal the docking point again, thereby forming three sealing treatments at the docking point between the first pipe 1 and the second pipe 2, greatly increasing the sealing performance of the docking point.
