Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and more specifically, to a leak-proof water conservancy pipeline connection device. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. The construction of water conservancy projects requires the use of water pipes to facilitate the control of water flow.

[0003] After searching, the existing patent (publication number: CN216976124U) discloses a leak-proof water conservancy pipeline for water conservancy projects, including a first water conservancy pipeline, one side of the first water conservancy pipeline is connected to the second water conservancy pipeline, and the outer side of the first water conservancy pipeline is movably sleeved with a first reinforcement sleeve; the device is provided with an auxiliary sealing mechanism, and the support of the connection part between the first water conservancy pipeline and the second water conservancy pipeline is strengthened by the first reinforcement sleeve and the second reinforcement sleeve, thereby strengthening the sealing performance between the first water conservancy pipeline and the second water conservancy pipeline, and achieving the purpose of preventing water leakage: the device is provided with a reinforcement mechanism, which can easily complete the installation and fixation of the installation sleeve, and when the first water conservancy pipeline and the second water conservancy pipeline are placed on the corresponding installation frame, the protection of the outer side of the first water conservancy pipeline and the second water conservancy pipeline is strengthened by the installation sleeve, thereby reducing the easy deformation of the outer side of the first water conservancy pipeline and the second water conservancy pipeline, and extending the service life of the device. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] In existing water conservancy pipelines, since the pipe connection device may be located far away from the valve in the pipeline system, the water flow cannot be directly cut off by the valve. When dismantling or replacing the pipe connection device, if the water flow is not cut off and the operation is carried out directly, it may cause water leakage, resulting in flooding at the work site and even damage to equipment. In addition, due to long-term contact with water flow, water conservancy pipeline facilities will produce dirt both inside and outside, requiring frequent replacement and maintenance to keep the device functioning well. When fixing the device, it will make it difficult to disassemble and assemble. Therefore, it is necessary to cut off the water flow to create a safe working environment for maintenance work and facilitate the disassembly and assembly of the pipe connection device.

[0005] Therefore, in response to the above problems, a leak-proof water conservancy pipeline connecting device is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4 The leak-proof water conservancy pipe connection device shown includes an adapter mechanism 1, a connecting pipe 5, and a water pipe 10. The adapter mechanism 1 has grooves 2 at both ends, and the inner surface of the groove 2 has a first internal thread 3. The connecting pipe 5 is respectively provided at both ends of the adapter mechanism 1, and the water pipe 10 is respectively provided at both ends of the connecting pipe 5.

[0025] A first external thread 4 is provided on one side of the opposite surfaces of the two sets of connecting pipes 5, and a sealing ring 41 is provided on one side of the opposite surfaces of the two sets of first internal threads 3. The first internal threads 3 and the first external threads 4 are engaged with each other, and one end of the opposite surfaces of the two sets of connecting pipes 5 respectively abuts against the surface of the two sets of sealing rings 41, and a valve 6 is provided at the center of the two sets of connecting pipes 5.

[0026] Among them: two groups of connecting pipes 5 connected to the water pipe 10 are connected through the adapter mechanism 1. When inspection, maintenance and cleaning are required, it is only necessary to close the valves 10 of the two groups of connecting pipes 5 to cut off the water flow in the water pipe 10, thereby effectively cutting off the water flow, reducing the risk of maintenance personnel and equipment being disturbed or damaged by water flow impact during inspection and maintenance. When disassembly is required, it is only necessary to rotate the adapter structure 1 to unscrew the first external threads 9 at both ends from the first internal threads 7 in the connecting groove 2 for disassembly, so that cleaning and maintenance can be conveniently carried out, and the sealing between the pipes can be increased by the sealing ring 41 to avoid water leakage due to excessive water pressure.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0029] As a preferred embodiment, the two sets of connecting pipes 5 are provided with a second internal thread 7 on the outward side, and the two sets of water pipes 10 are provided with a second external thread 9 on the opposite end, and the second internal thread 7 and the second external thread 9 are engaged with each other; further, the two sets of connecting pipes 5 are respectively engaged with the second external thread 9 of the water pipe 10 through the second internal thread 7 at the outward end, thereby being connected and fixed to the water pipe 10.

[0030] As a preferred embodiment, the inner cavities of the adapter mechanism 1, the connecting pipe 5 and the water pipe 10 are all provided with a tube cavity 11, each group of tube cavities 11 are interconnected, and the inner diameter of each group of tube cavities 11 is the same; further, through the design of the tube cavity 11, the water flow can flow smoothly between the adapter mechanism 1, the connecting pipe 5 and the water pipe 10, reducing the obstruction of the water flow at the pipe connection, improving the patency of the water flow, and helping to maintain the stability of the water flow and prevent water pressure loss or water flow blockage.

[0031] As a preferred embodiment, a rubber ring 8 is provided on one side of the opposite surfaces of the two groups of second internal threads 7, and the two groups of second external threads 9 are respectively in contact with the surfaces of the two groups of rubber rings 8; further, the second internal threads 7 of the two groups of connecting pipes 5 and the second external threads 9 of the two groups of water pipes 10 are respectively in contact with each other through the two groups of rubber rings 8 to increase the sealing of the pipeline and avoid the risk of leakage.

[0032] As a preferred embodiment, the adapter mechanism 1 and the two groups of connecting pipes 5 form a pipeline connection structure, and the outer diameters of the adapter mechanism 1 and the two groups of connecting pipes 5 are equal; further, since the outer diameters of the adapter mechanism 1 and the connecting pipes 5 are equal, they can fit very tightly when connected, ensuring the tightness of the pipeline connection and effectively preventing water leakage or water leakage.

[0033] The working process of the present invention is as follows: water flows through the adapter mechanism 1, the connecting pipe 5 and the tube cavity 11 of the water pipe 10, and the two groups of water pipes 10 are connected and fixed by meshing the second external thread 9 with the second internal thread 7 of the connecting pipe 5, and the sealing of the connection is enhanced by two groups of rubber rings 8. When inspection and maintenance are required, the valves 6 of the two groups of connecting pipes 5 are closed to cut off the water flow. After cutoff, the adapter mechanism 1 is rotated to drive the first internal threads 3 at both ends to be disassembled from the outer surfaces of the first external threads 4 of the two groups of connecting pipes 5, thereby discharging the remaining water and blockages of the pipeline connection mechanism, and carrying out inspection and maintenance in time. When installation is required, the two groups of first internal threads 3 in the groove 2 are meshed with the first external thread 4, and will abut against the surface of the two groups of sealing rings 41, thereby increasing the sealing of the pipeline connection mechanism. The above is the working principle of the leak-proof water conservancy pipeline connection device.

[0034] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
