Connecting mechanism of water supply pipe for water conservancy project

Abstract

The utility model provides a connecting mechanism of water supply pipes for hydraulic engineering, which comprises flanges positioned at one ends of water pipes, a butt joint block is arranged between the two water pipes, two ends of the butt joint block are respectively provided with a side cylinder used for being inserted into the water pipes in the corresponding direction, and the butt joint block is fixedly connected with the flanges on the two sides through connecting rods. The length of the side cylinder is larger than 20 cm, after the side cylinder is inserted into the water pipes on the two sides, due to the fact that the continuous arc-shaped grooves are formed in the inner side of the side cylinder, the side cylinder can expand towards the outer side under the pressure of water flow in the water supply pipe, and therefore the outer side face of the side cylinder makes contact with the inner side face of the water pipe more tightly, the water flow pressure is larger, and the water flow pressure is larger. The connection effect between the butt joint block and the water pipe is better, the butt joint block is not prone to loosening due to friction generated between the side cylinder and the water pipe, and therefore stable operation of the water supply pipeline is guaranteed.

Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a connecting mechanism for a water supply pipe used in water conservancy projects. 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. Water is a precious resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals.

[0003] Water supply pipes are needed in water conservancy projects. The two existing water supply pipes are directly connected by flanges. After long-term use, the bolts fixing the flanges are prone to loosening, resulting in gaps at the water supply pipe connections, causing water leakage. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a connection mechanism for water supply pipes for water conservancy projects, and the technical solutions adopted are as follows:

[0005] A connection mechanism for a water supply pipe for a water conservancy project comprises a flange at one end of the water pipe, a docking block is arranged between two water pipes, and both ends of the docking block are respectively provided with a side tube for inserting into the water pipe in the corresponding direction, and the docking block is fixedly connected to the flanges on both sides by connecting rods.

[0006] Furthermore, an annular sealing protrusion is provided on the side where the flange contacts the docking block, and slots for inserting the sealing protrusion are provided on both sides of the docking block. Sealing rings in contact with the sealing protrusion are provided in the slots on both sides of the docking block to keep the whole sealed and prevent leakage of the water supply pipeline.

[0007] Furthermore, the length of the side tube extending into the water pipe is greater than 20 cm, and a continuous arc-shaped groove is provided on the inner side of the side tube.

[0008] Furthermore, the outer diameter of the side tube is equal to the inner diameter of the water pipe. After the side tube is inserted into the water pipe, under the action of water pressure, the contact between the side tube and the water pipe will be closer and greater friction will be generated, so that it will not loosen.

[0009] A sealing gasket is provided between the butt joint block and the flange to further increase the tightness of the connection.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The length of the side tube in the utility model is greater than 20 cm. After the side tube is inserted into the water pipes on both sides, since the inner side of the side tube is provided with a continuous arc-shaped groove, the side tube will expand outward under the pressure of the water flow in the water supply pipe, so that the contact between the outer side surface of the side tube and the inner side surface of the water pipe becomes tighter. The greater the water flow pressure, the better the connection effect between the docking block and the water pipe. In addition, due to the friction generated between the side tube and the water pipe, the docking block is not easy to loosen, thereby ensuring the stable operation of the water supply pipeline.

[0018] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0019] As attached Figure 1-4 shown.

[0020] A connection mechanism for water supply pipes for water conservancy projects includes two water pipes 1 that need to be connected, flanges 2 are provided on opposite sides of the two water pipes 1, a docking block 3 is provided between the two water pipes 1, and both ends of the docking block 3 are respectively provided with a side tube 31 for inserting into the water pipes 1 in the corresponding direction, and the docking block 3 is fixedly connected to the flanges 2 on both sides by connecting rods 4.

[0021] An annular sealing protrusion 21 is provided on one side of the flange 2 that contacts the docking block 3 , and slots 32 for inserting the sealing protrusion 21 are provided on both sides of the docking block 3 .

[0022] Sealing rings 5 ​​in contact with the sealing protrusions 21 are disposed in the slots 32 located on both sides of the docking block 3 .

[0023] The assembly process is as follows: place the docking block 3 between the two water pipes 1 to be connected, and insert the side tubes 31 on both sides of the docking block 3 into the corresponding inner sides of the water pipes 1 respectively, push the water pipes 1 and the docking block 3 so that the side tubes 31 are completely inserted into the water pipes 1, and during the side tube insertion process, ensure that the sealing protrusion 21 on the outside of the flange 2 corresponds to the slot 32, and after the flange 2 at the outer end of the water pipe 1 is tightly fitted with the docking block 3, the sealing protrusion 21 will squeeze the sealing ring 5 in the slot 32 to keep it sealed as a whole to prevent leakage of the water supply pipeline.

[0024] Finally, the connecting rod 4 is passed through the flange 2 of the water pipe 1 on one side, the docking block 3, and the flange 2 of the other water pipe 1 in sequence to achieve fixation between the three.
