Description

Technical Field

[0001] This utility model relates to the field of pipe joint technology, specifically to a Y-type flow guide tee pipe joint. Background Technology

[0002] In the pipeline transportation fields of petroleum and chemical industries, Y-type tees are key components for fluid diversion. In existing technologies, conventional Y-type tees employ an equal-diameter, equal-angle branch structure, with right-angle or obtuse-angle transitions at the junction of the main pipe and branch pipes. This results in severe turbulence and localized negative pressure during fluid diversion, causing head loss. Existing flow guiding devices mostly use flat baffles or simple arc-shaped plates, which, while mitigating impact, suffer from uneven flow diversion and stress concentration on the guiding surface. Long-term use can easily lead to pipe wall erosion and cracking. Therefore, we propose a Y-type flow guiding tee connector. Utility Model Content

[0003] The purpose of this invention is to address the problem that conventional Y-type tee pipes, with their equal-diameter, equal-angle branching structure, use right-angle or obtuse-angle transitions at the junction of the main pipe and branch pipes, leading to severe turbulence and localized negative pressure during fluid splitting, resulting in pressure head loss. Existing flow guiding devices often employ flat baffles or simple arc-shaped plates, which, while mitigating impact, suffer from uneven flow splitting and stress concentration on the guiding surface, and are prone to pipe wall erosion and cracking with long-term use. This invention provides a Y-type flow guiding tee pipe connector.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A Y-type flow guide tee pipe joint includes a symmetrically distributed main branch pipe and two branch pipes. A flow guide plate is fixedly installed at the center of the main branch pipe. Two rows of flow guide holes are opened on the surface of the flow guide plate, and a flow guide slope is provided at the inner end of the flow guide plate corresponding to the two branch pipes. Multiple flow guide grooves are evenly opened on the flow guide slope.

[0006] Furthermore, the guide plate is an arc-shaped aluminum plate with a radius of curvature R=1.5D, where D is the diameter of the main pipe.

[0007] Furthermore, the inclined surface of the guide ramp is tilted at an angle of 30 degrees to the axis of the guide plate, and the guide groove is a V-shaped guide groove with a depth of 2 millimeters.

[0008] Furthermore, T-shaped connecting strips are welded and fixed to the inner wall of the main branch pipe, and T-shaped slots are correspondingly opened at both ends of the guide plate. The two sides of the guide plate are welded and fixed to the inner wall of the main branch pipe by fillet welds.

[0009] Furthermore, the two sides of the branch pipe are fixedly connected to the inner end of the guide plate with a docking plug, and the inner end of the guide plate is provided with a docking socket, which is matched with the docking plug.

[0010] Furthermore, a rubber buffer sleeve is fixedly connected to the inner wall of the branch pipe, and a wedge-shaped cavity is fixedly connected to the center of the rubber buffer sleeve, with the large opening of the wedge-shaped cavity facing inward.

[0011] Furthermore, the inner wall of the wedge-shaped cavity is uniformly distributed with grid grooves.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, high-speed fluid impacts the guide plate through the main branch pipe, and some fluid enters the rear cavity through the guide hole to absorb the initial impact energy and reduce the stress on the pipe wall. The guide slope ensures that the water outlet maintains a sharp edge to maintain the jet velocity, reducing the impact force of the water flow on the pipe wall, reducing turbulent energy, and lowering the vibration amplitude of the pipeline. The guide plate can also effectively guide the fluid to be evenly distributed to the two branch pipes along the guide hole and guide slope, ensuring the stability and uniformity of the fluid during the distribution process, avoiding the generation of local negative pressure and turbulence, thereby significantly reducing head loss and improving pipeline transportation efficiency.

[0014] 2. This utility model, through its designed flow-guiding ramps and V-shaped flow-guiding channels, can guide the fluid to flow smoothly in a specific direction, reducing turbulence and local negative pressure, and further reducing head loss. Furthermore, this design ensures uniform distribution of the fluid in the branch pipes, improving pipeline transport efficiency.

[0015] 3. This utility model, through its rubber buffer sleeve and wedge-shaped cavity, can absorb the vibration and noise generated by fluid impact, reduce vibration transmission in the pipeline system, and improve system stability and quietness. Furthermore, the wedge-shaped cavity design enhances the elasticity of the rubber buffer sleeve, further improving its buffering effect and extending its service life. The larger opening of the wedge-shaped cavity faces inward, better adapting to the direction of fluid impact and improving buffering efficiency. Attached Figure Description

Two rows of flow guide holes 4 are opened on the surface of the flow guide plate 3, and a flow guide slope 5 is provided at the inner end of the flow guide plate 3 corresponding to the two branch pipes 2. Multiple flow guide grooves 6 are evenly opened on the flow guide slope 5.

[0023] In this embodiment, preferably, the guide plate 3 is an arc-shaped aluminum plate with a radius of curvature R=1.5D, where D is the diameter of the main pipe; by setting the arc-shaped aluminum plate, the impact force of the fluid on the guide plate 3 can be effectively dispersed, the stress concentration on the guide surface can be reduced, and the durability of the pipe joint can be improved.

[0024] In this embodiment, preferably, the inclined surface of the guide ramp 5 is tilted at a 30-degree angle to the axis of the guide plate 3, and the guide groove 6 is a V-shaped guide groove with a depth of two millimeters. Through the designed guide ramp 5 and V-shaped guide groove 6, the fluid can be guided to flow smoothly in a specific direction, reducing turbulence and the generation of local negative pressure, further reducing head loss. Furthermore, this design also ensures uniform distribution of fluid in the branch pipe 2, improving pipeline transport efficiency.

[0025] In this embodiment, preferably, T-shaped connecting strips 13 are welded and fixed to the inner wall of the main branch pipe 1, and T-shaped slots are correspondingly provided at both ends of the guide plate 3. The two sides of the guide plate 3 are welded and fixed to the inner wall of the main branch pipe 1 by fillet welds 9. Through the T-shaped connecting strips 13 and T-shaped slots, as well as the welding and fixing method of fillet welds 9, the stable installation of the guide plate 3 in the main branch pipe 1 can be ensured, avoiding displacement or loosening of the guide plate 3 during use, and ensuring the stability and reliability of the pipe joint. In addition, this fixing method can also improve the connection strength between the guide plate 3 and the main branch pipe 1, enhance the overall structural strength of the pipe joint, and extend its service life.

[0027] In this embodiment, preferably, a rubber buffer sleeve 10 is fixedly connected to the inner wall of the branch pipe 2, and a wedge-shaped cavity 11 is fixedly connected to the center of the rubber buffer sleeve 10, with the larger opening of the wedge-shaped cavity 11 facing inward. Through the rubber buffer sleeve 10 and the wedge-shaped cavity 11, vibrations and noise generated by fluid impact can be absorbed, reducing vibration transmission in the pipeline system and improving system stability and quietness. Furthermore, the design of the wedge-shaped cavity 11 enhances the elasticity of the rubber buffer sleeve 10, further improving its buffering effect and extending its service life. The larger opening of the wedge-shaped cavity 11 facing inward allows it to better adapt to the direction of fluid impact, improving buffering efficiency.

[0028] In this embodiment, preferably, the inner wall of the wedge-shaped cavity 11 is uniformly distributed with grid grooves 12; through the grid grooves 12, the grid grooves 12 generate multi-directional deformation when under pressure, which improves the energy absorption efficiency, further improves the buffering performance of the rubber buffer sleeve 10, and increases the contact area between the rubber buffer sleeve 10 and the fluid, thereby improving the buffering effect.

[0029] The working principle and usage process of this utility model are as follows: During use, high-speed fluid impacts the guide plate 3 through the main branch pipe 1. Some fluid enters the rear cavity through the guide hole 4, absorbing the initial impact energy and reducing the stress on the pipe wall. The guide slope 5 ensures that the water outlet maintains a sharp edge to maintain the jet velocity, reducing the impact force of the water flow on the pipe wall, reducing turbulent energy, and lowering the vibration amplitude of the pipeline. The guide plate 3 can also effectively guide the fluid to be evenly distributed to the two branch pipes 2 along the guide hole 4 and the guide slope 5, ensuring the stability and uniformity of the fluid during the distribution process, avoiding the generation of local negative pressure and turbulence, thereby significantly reducing head loss and improving pipeline transportation efficiency.
