Description

Technical Field

[0001] The utility model relates to the field of three-way joints, in particular to a three-way with uniform flow distribution. Background Technique

[0002] A three-way joint, also known as a pipe fitting three-way or three-way pipe fitting, is a kind of pipe connector, mainly used to change the fluid direction, especially at the branch pipe of the main pipeline. It has three openings, namely one inlet and two outlets, or two inlets and one outlet, and can be divided into T-shaped and Y-shaped in shape, and there are also equal-diameter pipe openings and different-diameter pipe openings.

[0003] The current three-way pipe fittings will cause different flow velocities of water in the pipes when connecting pipes of different lengths, thus affecting the water output. The longer pipe may reduce the flow velocity due to the increase of frictional resistance, which in turn affects the flow distribution. If the flow distribution is uneven, it will cause excessive flow in some branch pipes and insufficient flow in other branch pipes, which will affect the operation efficiency of the whole system. Moreover, uneven flow distribution will also increase the erosion and wear of the fluid on the inner wall of the pipe. In the long run, it will lead to problems such as thinning and leakage of the pipe. For this reason, a three-way with uniform flow distribution is proposed to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1-3, an embodiment provided by the present utility model: a tee with uniform flow distribution, comprising a tee pipe 1. The tee pipe 1 is in a T shape. One vertical part of the T shape is the main pipe, and the other two outlets are branch pipes. Inside the two groups of branch pipes of the tee pipe 1, a group of flow-limiting seats 2 are respectively fixedly connected. Inside the flow-limiting seat 2, a sliding groove 3 is provided. On the inner wall of the side of the sliding groove 3, a rounded corner sliding groove 4 is provided. There are two groups of the rounded corner sliding grooves 4, which are symmetrically arranged front and back on the inner wall of the side of the sliding groove 3. Inside the rounded corner sliding groove 4, a sliding column 5 is slidably connected. The rounded corner sliding groove 4 restricts the sliding column 5 to slide only up and down along the inner wall of the rounded corner sliding groove 4. On the outside of the sliding column 5, a slider 6 is fixedly connected. There are two groups of the sliders 6, which are symmetrically arranged front and back inside the sliding groove 3. Inside the sliding groove 3, a flow-limiting plate 7 for restricting the flow rate of the branch pipe of the tee pipe 1 is slidably connected. On the inner side of the flow-limiting plate 7, a vertical sliding groove 8 is provided. The outer circumference of the slider 6 is slidably connected inside the vertical sliding groove 8. The vertical sliding groove 8 restricts the slider 6 to slide only up and down along the inner wall of the vertical sliding groove 8. On the inner side of the sliding column 5, a sliding assembly is provided. The sliding assembly includes a sliding rod 9. The outside of the sliding rod 9 is fixedly connected to the inner side of the sliding column 5. One end of the inner side of the sliding rod 9 is slidably connected to the outer circumference of a sliding seat 10. The sliding seat 10 restricts the sliding rod 9 to slide only back and forth along the inner wall of the sliding seat 10. Inside the sliding assembly, a threaded block 11 is fixedly connected. The inner side of the sliding seat 10 is fixedly connected to the outer circumference of the threaded block 11. The outer circumference of the threaded block 11 is slidably connected inside the sliding groove 3. The sliding groove 3 restricts the sliding seat 10 to slide only up and down and cannot rotate. Inside the threaded block 11, a threaded rod 12 is threadedly connected. By rotating the threaded rod 12, the threaded rod 12 can drive the threaded block 11 to slide only up and down along the axis direction of the threaded rod 12. The outer circumference of the threaded rod 12 is rotatably connected to a rotating seat 13. The bottom end of the rotating seat 13 is fixedly connected to the top of the branch pipe of the tee pipe 1.

[0032] Refer to Figure 1 , Figure 4 and Figure 5, a fixing ring 14 is fixedly connected to the outside of the tee pipe 1. There are three groups of fixing rings 14, which are respectively arranged on the outer peripheries of the three openings of the tee pipe 1. The outside of the fixing ring 14 is detachably connected to a connecting ring 16 through bolts 15. There are two groups of bolts 15, which are symmetrically arranged in the front and back of the fixing ring 14. By rotating the bolts 15, the front and rear groups of fixing rings 14 can be made to approach each other. Ring grooves 17 are provided on the inner sides of the connecting ring 16 and the fixing ring 14. A ramp block 18 is fixedly connected to the inner wall of the side surface of the ring groove 17. An extrusion ring 19 is in contact with the inner side of the ramp block 18. The slope of the ramp block 18 is adapted to the outer inclined surface of the extrusion ring 19. The inner side of the extrusion ring 19 is slidably connected and the outer periphery is arranged inside the ring groove 17. A deformation notch 20 for facilitating the deformation of the extrusion ring 19 is provided on the front surface of the extrusion ring 19. When the ramp block 18 moves inward, the extrusion ring 19 will be tightened along the inclined surface, and the deformation notch 20 will become smaller. A sealing rubber sleeve 21 with good sealing effect is clamped inside the extrusion ring 19. The inner sides of the fixing ring 14 and the connecting ring 16 are in contact with the inner side of the sealing rubber sleeve 21. The inner side of the sealing rubber sleeve 21 is in contact with the outer periphery of the pipe orifice of the tee pipe 1. When the extrusion ring 19 is tightened inward, it will squeeze the sealing rubber sleeve 21, increasing the sealing performance of the sealing rubber sleeve 21.

[0033] Working principle: When it is desired to adjust the flow rate passing through the two branches of the tee pipe 1, rotate the threaded rod 12. The threaded rod 12 drives the threaded block 11 to slide upward along the sliding groove 3. The threaded block 11 drives the sliding column 5 to move upward through the sliding assembly. While the sliding column 5 moves upward, it moves inward. The flow limiting plate 7 is driven by the slider 6 to move from both sides to the center, increasing the gap between the flow limiting seat 2 and the branch pipe of the tee pipe 1. Thus, the flow rate passing through the two branches of the tee pipe 1 can be conveniently adjusted, making the flow rates passing through the two branches equal, ensuring the operating efficiency of the system, and reducing pipeline wear. When it is desired to connect a pipeline to the tee pipe 1, insert the pipeline into the inside of the connecting ring 16 and make contact with the inner side of the sealing rubber sleeve 21. When the pipeline abuts against the pipe orifice of the tee pipe 1, tighten the bolts 15. The bolts 15 drive the connecting ring 16 to approach the fixing ring 14, making the inner ring grooves 17 of the connecting ring 16 and the fixing ring 14 approach each other. The ramp blocks 18 on both sides approach each other. The extrusion ring 19 is squeezed through the inclined surface, causing the extrusion ring 19 to tighten inward. Thus, the sealing rubber sleeve 21 is squeezed inward, improving the sealing performance when the pipeline is connected to the tee pipe 1.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
