Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection devices, in particular to a pipeline connection device for pressurizing a tap water pipeline. Background Art

[0002] With the acceleration of urbanization and the continuous growth of the population, high-rise buildings are becoming increasingly numerous. In these buildings, the natural pressure of the municipal water supply alone cannot transport water to the upper floors due to the water's own weight. For example, the typical municipal water supply pressure can only meet the water needs of buildings below six stories. However, for floors seven and above, secondary water pressure boosting is required. This has prompted the development of water pipe pressure boosting systems, and the importance of pipe connection devices, as a key component of these systems, has become increasingly prominent.

[0003] A pipe connection device for pressurizing a tap water pipe in the prior art may leak when it is connected to other pipes through a flange due to the setting of the flange gap, and its practicality is poor. In addition, a pipe connection device for pressurizing a tap water pipe in the prior art does not have a mechanism to stabilize the other pipes when connected to the other pipes, and its stability is poor. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art that when a flange is connected to other pipes, water leakage may occur at the joint due to the setting of the flange gap, and there is no mechanism to stabilize the other pipes when connecting them, resulting in poor stability. A pipe connecting device for pressurizing a tap water pipe is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a pipe connecting device for boosting tap water pipes, comprising a connecting pipe, arc-shaped pipes are fixed at both ends of the connecting pipe, flanges are fixed on the outer walls of the two arc-shaped pipes at the opposite ends, sealing gaskets are fixed on the opposite ends of the two flanges, a fixing block is fixed on the outer wall of the connecting pipe, a first bracket is provided at both ends of the fixing block, a second bracket is provided above the two first brackets, and a stabilizing frame is fixed inside the first bracket and the second bracket.

[0006] Preferably, the number of the first brackets and the number of the second brackets are both two, and both ends of the stabilizing frame are respectively fixed to the two corresponding first brackets or second brackets.

[0007] Preferably, mounting plates are fixed to both ends of the two first brackets and the two second brackets, and mounting holes are provided in the mounting plates.

[0008] Preferably, both ends of the fixing block are provided with inner cavities, connecting columns are fixed on the inner walls of the inner cavities, and one end of the second bracket and the first bracket are both slidably connected to the connecting columns.

[0009] Preferably, a soft pad is fixed to the opposite ends of the two stabilizing frames, and a hole matching the flange is opened in the sealing pad.

[0010] Preferably, the two arc-shaped tubes are shaped as gradually expanding or contracting pipes, and an arc angle is provided at one end of the stabilizing frame.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] In the present invention, through the provision of the sealing gasket, when the pipe flanges to be docked are docked and installed with the flanges of the present invention, the sealing gasket will be squeezed, and due to the flexibility of the sealing gasket, the small gap between the two flanges will be filled, preventing water from leaking from the flange interface, ensuring that all the pressurized water flows in the pipeline, and there will be no pressure loss due to leakage, which is more practical. When the connecting pipe is docked with other pipes through the two flanges, the user can slide the first bracket and the second bracket toward each other, which can drive the two stable frames to move toward each other, and then by driving bolts into the mounting plate, the two stable frames can firmly support the docked pipes, which is more practical. The shape of the arc pipe is a gradually expanding or contracting pipe, so that the water flow can transition smoothly, reducing vortices and turbulence caused by sudden changes in pipe diameter, bends and other factors, which is more practical.

A second bracket 9 is provided above the two first brackets 8, and a stabilizing frame 10 is fixed inside the first bracket 8 and the second bracket 9.

[0021] The effect achieved by the entire embodiment 1 is that, through the setting of the sealing gasket 4, when the pipe flange 3 to be docked is docked and installed with the flange 3 of the present invention, the sealing gasket 4 will be squeezed, and due to the flexibility of the sealing gasket 4, the small gap between the two flanges 3 will be filled, preventing water from leaking from the interface of the flange 3, ensuring that all the pressurized water flows in the pipeline, and there will be no pressure loss due to leakage, which is more practical. When the connecting pipe 1 is docked with other pipelines through the two flanges 3, the user can slide the first bracket 8 and the second bracket 9 toward each other, which can drive the two stabilizing frames 10 to move toward each other, and then by driving bolts into the mounting plate 12, the two stabilizing frames 10 can firmly support the docked pipelines, which is more practical.

[0022] Example 2, as Figure 1-4 As shown, the number of the first bracket 8 and the second bracket 9 are both two, and the two ends of the stabilizing frame 10 are respectively fixed to the two first brackets 8 or the second bracket 9 corresponding thereto, and the two first brackets 8 and the two second brackets 9 are fixed with mounting plates 12 at both ends, and mounting holes 13 are provided in the mounting plates 12. An inner cavity 6 is provided at both ends of the fixing block 5, and a connecting column 7 is fixed on the inner wall of the inner cavity 6.

When the connecting pipe 1 is docked with other pipes through the two flanges 3, the user can slide the first bracket 8 and the second bracket 9 towards each other, which can drive the two stable brackets 10 to move towards each other.
