[0002] Pipelines are one of the important ways to transport liquids. When it is necessary to change or divert the flow direction of liquids during the use of pipelines, pipe fittings are required. For example, a tee fitting is needed when diverting the flow.

[0003] Existing tee fittings often only serve a diversion function, and their inner diameter is usually fixed. When it is necessary to adjust the flow rate, it needs to be adjusted at the main valve, which is not precise enough. Therefore, an adjustable flow tee fitting is needed to solve this problem. Utility Model Content

[0020] Please see Figure 1-3 A flow-adjustable tee connector includes a tee body 1, with connecting cylinders 2 connected to both the left and right ends of the tee body 1. Movable cylinders 3 located inside the connecting cylinders 2 are slidably connected to both the left and right sides inside the tee body 1. Through holes 4 are opened on the upper and lower sides of the outer walls of the two movable cylinders 3. A first rotating shaft 5 is rotatably connected through the interior of the tee body 1. A gear 6 is fixedly connected to the outer wall of the first rotating shaft 5. Two straight racks 7 are meshed with the outer wall of the gear 6. The other ends of the two straight racks 7 are fixedly connected to the two movable cylinders 3 respectively.

[0021] A turntable 8 is fixedly connected to the lower end face of the first rotating shaft 5. A worm gear 9 is fixedly connected to the outer wall of the turntable 8. A second rotating shaft 10 is rotatably connected between the two connecting cylinders 2. A worm 11 that meshes with the worm gear 9 is fixedly connected to the middle of the second rotating shaft 10.

[0022] In this embodiment: the liquid flows into the two movable cylinders 3 through the three-way body 1 and into the two connecting cylinders 2 through the through holes 4 on the outer wall of the movable cylinders 3. The second rotating shaft 10 is rotated, which drives the worm gear 11 to rotate, which in turn drives the worm wheel 9 to rotate. The worm wheel 9 further drives the turntable 8 to rotate, which in turn drives the first rotating shaft 5 to rotate. The first rotating shaft 5 further drives the gear 6 to rotate, which in turn drives the two movable cylinders 3 to move synchronously relative to each other or in opposite directions along the three-way body 1 through the rack 7. This adjusts the degree of closure of the multiple through holes 4, thereby precisely adjusting the flow rate of the liquid flowing out of the through holes 4. It has the characteristics of simple adjustment and precise control.

[0023] As a technical optimization of this utility model, two symmetrically distributed limiting blocks 12 are fixedly connected to the outer walls of the two movable cylinders 3, and four limiting grooves 13 matching the limiting blocks 12 are opened on the inner wall of the three-way body 1.

[0024] In this embodiment, the movable cylinder 3 can be limited by the cooperation of the limiting block 12 and the limiting groove 13 to prevent the movable cylinder 3 from coming out of the tee body 1.

[0025] As a technical optimization of this utility model, the inside of the tee body 1 is provided with a sleeve 15 that is rotatably connected to the first rotating shaft 5. The outer wall of the sleeve 15 is fixedly connected with a plurality of circumferentially distributed connecting rods 14, and the other end of the plurality of connecting rods 14 is fixedly connected to the inner wall of the tee body 1.

[0026] In this embodiment, the upper end of the first rotating shaft 5 can be limited by the connecting rod 14 and the sleeve 15 to make the rotation of the first rotating shaft 5 stable.

[0027] As a technical optimization of this utility model, the inner diameter of the connecting cylinder 2 is larger than the inner diameter of the tee body 1.

[0028] In this embodiment: by setting the inner diameter of the connecting cylinder 2 to be larger than the inner diameter of the three-way body 1, it is convenient for liquid to flow out from the movable cylinder 3 through the through hole 4.

[0029] As a technical optimization of this utility model, the movable cylinder 3 is an open shape with one end closed.

[0030] In this embodiment: by setting the movable cylinder 3 as an open shape with one end closed, it is convenient for liquid to enter the movable cylinder 3 and flow out from the through hole 4.

[0031] As a technical optimization of this utility model, the outer wall of the second rotating shaft 10 is provided with an anti-slip pad.

[0032] In this embodiment, an anti-slip pad is provided on the outer wall of the second rotating shaft 10 to facilitate the rotation of the second rotating shaft 10.

[0033] The working principle and usage process of this utility model are as follows: When adjusting the flow rate of the three-way body 1, the second rotating shaft 10 is rotated. The second rotating shaft 10 drives the worm gear 11 to rotate, which in turn drives the worm wheel 9 to rotate. The worm wheel 9 further drives the turntable 8 to rotate, which in turn drives the first rotating shaft 5 to rotate. The first rotating shaft 5 further drives the gear 6 to rotate, which in turn drives the two movable cylinders 3 to move synchronously relative to each other or in opposite directions along the three-way body 1 through the rack 7. This adjusts the degree of closure of multiple through holes 4, thereby precisely adjusting the flow rate of liquid flowing out of the through holes 4. When both movable cylinders 3 are fully inside the three-way body 1, the four through holes 4 can be completely closed, thereby completely blocking the flow of liquid from the three-way body 1. This model features simple adjustment and precise control.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
