Problems solved by technology

[0002] Tee is a simple diversion or confluence part, mainly in T-shape and Y-shape, etc. It is widely used in fluid mechanical systems and other fields. Some tees are also easy to cause fluid-solid coupling problems, resulting in vibration and noise, which restricts system performance, especially the performance improvement of high-pressure pipelines and large pipeline systems

Embodiment Construction

[0013] For specific implementation, see figure 1 , figure 2 . The present invention will be further described in detail through specific embodiments below.

[0014] The specific embodiment is that the three-way structure includes a main channel (1), two sub-channels (2), two elbow sections (3) and a partition tongue (4), and the two sub-channels pass through (2) The partition tongue (4) is connected with the main passage (1), and the cross-sectional area ratio on both sides of the end of the partition tongue (4) is equal to the cross-sectional area ratio of the two sub-passages.

[0015] Furthermore, each curved section smoothly transitions from a D-shaped section to a circular section, leading to a sub-channel.

[0016] The design method of the low flow resistance tee structure is to use CAD software to simulate the shape of the elbow with a set of more than two closed section curves (5). The two port sections of the elbow are circular and D-shaped respectively. The cros...

Abstract

The invention belongs to the field of fluid machinery systems and relates to a low-flow-resistance tee joint structure. According to a method, a three-way flow channel is designed based on parametrization, so that the flow field in the tee joint uniformly and smoothly changes, the speed and pressure change of a fluid passing through a three-way section is reduced, the eddy is reduced, the flow confluence or distribution energy loss is reduced, the purpose of reducing the flow resistance is achieved, and the flow resistance can be reduced by 30-80% in general.

Description

technical field [0001] A low flow resistance tee structure belongs to the technical field of fluid mechanical systems, and relates to the improvement of the tee structure. Background technique [0002] Tee is a simple diversion or confluence part, mainly in T-shape and Y-shape, etc. It is widely used in fluid mechanical systems and other fields. These tees are also easy to cause fluid-solid coupling problems, generate vibration and noise, and restrict system performance, especially the improvement of high-pressure pipeline and large pipeline system performance. Contents of the invention [0003] The purpose of the present invention is to provide a three-way structure with low flow resistance. [0004] The technical solution of the present invention: the parametric design of the three-way flow channel in the present invention makes the flow field in the three-way change evenly and smoothly, reduces the velocity and pressure changes of the fluid passing through the three-wa...
