Description

Technical Field

[0001] This utility model relates to the field of tee fittings technology, specifically a high-strength tee fitting. Background Technology

[0002] In high-pressure fluid transportation or complex operating conditions, the structural strength and fluid performance optimization of tee fittings are crucial. Tee fittings are susceptible to stress concentration, vibration fatigue cracking, and localized erosion in the connection area. Existing tee fittings sometimes employ external reinforcing ribs to improve strength, but these ribs only alleviate external stress and cannot solve the problem of internal wall erosion. Others use thickened designs, but uniform thickness designs fail to adjust wall thickness according to stress, resulting in low material utilization. Therefore, to address these issues and further optimize the fitting and improve its strength, we provide a high-strength tee fitting. Utility Model Content

[0003] The purpose of this utility model is to provide a high-strength tee fitting, optimize the fitting structure, and improve the fitting strength.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-strength tee fitting, comprising a main pipe body and a branch pipe body arranged perpendicular to the axis of the main pipe body, wherein the connection area between the branch pipe body and the main pipe body is provided with composite reinforcing ribs, the middle wall thickness of the branch pipe body is greater than the wall thickness at both ends, and the wall thickness of the connection area of ​​the main pipe body is greater than the wall thickness at the ends.

[0005] The composite reinforcing ribs include radial reinforcing ribs, axial reinforcing ribs and transition reinforcing ribs. The radial reinforcing ribs are distributed radially along the outer wall of the branch pipe body. The axial reinforcing ribs are arranged at axial intervals along the outer wall of the branch pipe body. The transition reinforcing ribs are fixed on the outer peripheral surface of the main pipe body and extend to connect with the branch pipe body at the branch pipe body location.

[0006] A flow guide block is provided in the middle of the inner wall of the branch pipe corresponding to the position of the main pipe. The flow guide block includes a connecting surface that fits against the inner wall of the branch pipe, an inclined flow guide surface that connects with the connecting surface and faces both ends of the branch pipe, and an arc-shaped surface that connects the inclined flow guide surface and the connecting surface.

[0007] Preferably, the inclined guide surfaces on both sides of the guide block converge in the middle through an arc-shaped surface, and the arc-shaped surface is oriented towards the main body.

[0008] Preferably, the radial reinforcing rib is a strip-shaped rib extending axially along the branch pipe body, and the radial reinforcing rib is connected with the axial reinforcing rib to form a mesh-like rib, and the radial reinforcing rib is provided with a cylinder connected to the axial reinforcing rib.

[0009] Preferably, the axial reinforcing rib is an arc-shaped rib arranged around the outer wall of the branch pipe body, and the arc-shaped rib in the connection area between the branch pipe body and the main pipe body connects to the main pipe body. The distribution density of the axial reinforcing rib in the connection area between the branch pipe body and the main pipe body is higher than the distribution density in the branch pipe body area.

[0010] Preferably, the two ends of the branch pipe are external insertion ports, and the end of the main pipe is an internal insertion port.

[0011] Preferably, the main body has a raised ring at the tail of the inner insertion port for connecting transition reinforcing ribs;

[0012] The transition stiffeners are ribs evenly distributed along the radial direction of the main body.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes a composite reinforcement structure in the stress concentration connection area. Through the synergistic effect of radial stiffeners, axial stiffeners, transition stiffeners, and flow guide blocks, the composite stiffeners are densely packed and intersecting at the connection point, increasing the wall thickness of the pipe in the connection area. The flow guide blocks divide the fluid in the main pipe, making the flow distribution in the branch pipe smoother. The flow guide blocks also prevent the fluid from directly impacting the inner wall of the branch pipe. The flow guide blocks also act as an internal support structure, working together with the external composite stiffeners to form a composite reinforcement system with internal support and external clamping, significantly improving the pipe's resistance to deformation and fatigue life under high pressure conditions.
