Description

Technical Field

[0001] This utility model relates to the field of pipeline regulation technology, specifically a pipeline fluid self-regulation mechanism. Background Technology

[0002] Water pipes are pipes that supply water. There are three types of water pipes: metal pipes, plastic-coated metal pipes, and plastic pipes. When water pipes transport liquids, they mostly transport them from the source through a main pipe, and then through several branch pipes. Since the main pipe connects to several branch pipes, if multiple branch pipes are used at the same time, the water inflow to the branch pipes will decrease, the liquid pressure in the branch pipes will decrease, and the pressure at the outlet of the branch pipes will decrease. When some branch pipes need to work at a certain pressure, the water pressure will fluctuate significantly, thus affecting the flow of water in the pipeline.

[0003] Based on this, a self-regulating mechanism for pipeline fluid is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-5As shown, a pipeline fluid self-regulating mechanism includes an adapter 12. An inlet pipe 11 and a first drain pipe 13 are respectively connected to both ends of the adapter 12. Both the inlet pipe 11 and the first drain pipe 13 are fixedly connected to the adapter 12 via connecting flanges 15. A second drain pipe 14 is coaxially arranged inside the first drain pipe 13. A drain plate 17 is fixedly arranged at one end of the adapter 12 and at one end of the first drain pipe 13 and the second drain pipe 14. One side of the drain plate 17 is in close contact with one end of the first drain pipe 13 and the second drain pipe 14. A plurality of first drain holes are arranged in a circular array on the drain plate 17. A circular through hole with the same inner diameter as the second drain pipe 14 is provided in the middle of the drain plate 17. A pressurized conveying channel is formed between the inner side of the first drain pipe 13 and the outer side of the second drain pipe 14. An adjusting component is provided inside the adapter 12 for adjusting the water inlet volume of the pressurized conveying channel. The adjusting component facilitates the adjustment of the water pressure at the output ends of the first drain pipe 13 and the second drain pipe 14 according to the water flow velocity inside the inlet pipe 11.

[0024] The second drain pipe 14 has a circular array of several first fixing rods at one end, and one end of each first fixing rod is fixedly connected to the inner side of the limiting ring 16. The first drain pipe 13 has a limiting groove on the inner side of the connecting flange 15 at one end, and the limiting ring 16 is fitted in the limiting groove. In use, it is convenient to fix one end of the second drain pipe 14, and at the same time, it is convenient for the first drain pipe 13 and the second drain pipe 14 to be tightly attached to one side of the drain plate 17.

[0025] The adjusting component includes an adjusting plate 18, which is closely attached to the drain plate 17. A stop ring is closely attached to one side of the adjusting plate 18 and is fixedly mounted on one end of the adapter 12. The adjusting plate 18 and the first drain hole are both provided with second drain holes. One side of the adjusting plate 18 is fixedly connected to several working ends of the connecting frame 19. The connecting frame 19 is fixedly mounted on one end of the drive shaft 20. The other end of the drive shaft 20 is provided with a drive assembly for driving the adjusting plate 18 to rotate.

[0026] The drive assembly includes a first bevel gear 21, which is fixedly mounted on one end of a drive shaft 20. The first bevel gear 21 is disposed inside a second fixed tube 24, which is fixedly mounted inside an adapter 12. One end of the drive shaft 20 is rotatably connected to one side of the interior of the second fixed tube 24. The second fixed tube 24 has a circular array of mounting holes, each containing a mounting shaft. The other end of each mounting shaft is fixedly fitted with a second bevel gear, which meshes with the first bevel gear 21. A deflection plate 25 is fixedly mounted on each mounting shaft, with its side fixedly connected to the mounting shaft. A fixing ring 26 is located inside the adapter 12 at a position corresponding to the mounting shaft. Limiting holes are located on the inner side of the fixing ring 26 at the other end of the mounting shaft. A mounting disc is fixedly mounted on the drive shaft 20, rotatably mounted inside a first fixed tube 23, which is fixedly mounted inside the adapter 12. In the unit, a torsion spring 22 is provided between one side of the mounting plate and one end of the first fixed pipe 23. In use, when the water flow velocity inside the inlet pipe 11 is high, after the water flows into the adapter 12 from the output end of the inlet pipe 11, the fluid causes the deflection plate 25 to deflect. The deflection plate 25 drives the mounting shaft to rotate. The mounting shaft drives the transmission shaft 20 to rotate through the meshing of the second bevel gear and the first bevel gear. The transmission shaft 20 drives the adjusting plate 18 to rotate through the connecting frame 19. According to the deflection angle of the deflection plate 25, the adjusting plate 18 rotates to a fixed angle. Through the overlap of the first drain hole and the second drain hole, the fluid flows out through the second drain pipe 14 and the pressurized conveying channel. When the water pressure at the output end of the inlet pipe 11 decreases, the deflection plate 25 deflects back to the initial position under the action of the torsion spring 22. At the same time, the overlap area of ​​the first drain hole and the second drain hole decreases. When the adjusting plate 18 completely closes the first drain hole, the fluid is discharged only through the interior of the second drain pipe 14.

[0027] The deflection plate 25 is provided with several inclined strips 27 at equal intervals on one side. The inclined strips 27 are all inclined. In use, they can increase the resistance when the flow passes through one side of the deflection plate 25, thereby making it easier to push the deflection plate 25 to deflect. It is worth noting that the inclined strips 27 can be selected according to the actual use. If the deflection plate needs to be deflected accurately, the inclined strips 27 can be omitted.

[0028] The second fixed tube 24 and the deflection plate 25 are both provided with a first limiting plate 29. One end of the connecting frame 19 is fixed with an extension plate. The first fixed tube 23 and the extension plate are provided with a second limiting plate 30. In use, it is convenient to limit the rotation angle of the deflection plate 25 and the adjusting plate 18.

[0029] A conical block 28 is fixedly provided at one end of the second fixed pipe 24. The conical block 28 is arranged in a conical shape, which helps to reduce the impact of fluid on one end of the second fixed pipe 24 during use.

[0030] The above embodiment discloses a pipeline fluid self-regulating mechanism. When the water flow velocity inside the inlet pipe 11 is high, after the water flows into the adapter 12 from the output end of the inlet pipe 11, the fluid causes the deflection plate 25 to deflect. The deflection plate 25 drives the mounting shaft to rotate. The mounting shaft drives the transmission shaft 20 to rotate through the meshing of the second bevel gear and the first bevel gear. The transmission shaft 20 drives the adjusting plate 18 to rotate through the connecting frame 19. According to the deflection angle of the deflection plate 25, the adjusting plate 18 rotates to a fixed angle. Through the overlap of the first drain hole and the second drain hole, the fluid flows out through the second drain pipe 14 and the pressurized conveying channel. When the water flow pressure at the output end of the inlet pipe 11 decreases, under the action of the torsion spring 22, the deflection plate 25 deflects to the initial position. At the same time, the overlap area of ​​the first drain hole and the second drain hole decreases. When the adjusting plate 18 completely closes the first drain hole, the fluid is discharged only through the interior of the second drain pipe 14.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
