Abstract
The utility model provides a T-shaped three-way joint with a unique inner wall structure, which can effectively ensure the conformity of pressure and flow of outlets at two ends in an air supply pipeline of a non-symmetrical structure. The T-shaped three-way joint comprises an inlet and two outlets, wherein the outlets comprise a direct outlet and a side outlet, and a three-way cavity channel is formed among the inlet and the outlets. The T-shaped three-way joint is characterized in that the tail end of the joint part of an inlet channel adopts a reduced opening structure; the reduced opening structure is communicated with the channel of the direct outlet after reducing the diameter of the channel; the side outlet is positioned right above; and the channel of the side outlet is communicated with the joint part of the inlet channel. The T-shaped three-way joint can effectively improve the pressure of side flowing in the air supply pipeline of a non-symmetrical structure, enable the flow of the outlets at two ends to maintain conform or achieve the flow ratio required by design, control the pressure and the flow ratio of the outlets at two ends to achieve the ratio required by the design, and effectively simplify the air supply pipeline of the non-symmetrical structure; and the property is reliable.
Description
Technical field
The utility model relates to a kind of T type tee union, relates to specifically to be applicable under the non-symmetry structure pipeline, can keep the extraordinary T type tee union of outlet pressure at two ends, flow-rate ratio.
Background technique
In the pipeline of fluids such as conveying gas, liquid, when needs are shunted, what generally adopt at present is a kind of T-shape tee union of ordinary construction, and this common tee union only could be able to keep the conformity of two ends outlet pressure and flow in the symplex structure pipeline.
Being in the product of representative,, often need to adopt the supply air line of non-symmetry structure owing to the restriction of installation conditioned disjunction applied environment with the emergent floating system of helicopter.At this moment, common tee union can cause side outlet pressure low, and the lateral flow quantity not sufficient can not guarantee the conformity of two ends outlet pressure and flow, more uncontrollable outlet both sides reach the pressure and the flow-rate ratio of designing requirement, can not satisfy the application demand of non-symmetry structure supply air line.Therefore, need design extraordinary T type tee union, with pressure, the flow-rate ratio that keeps exporting pressure at two ends, flow unanimity under the non-symmetry structure supply air line or reach designing requirement.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency at above-mentioned existence, and a kind of T type tee union of special interior wall construction is provided, and this special type threeway can effectively keep the conformity of outlet pressure at two ends and flow in the non-symmetry structure supply air line.
The technological scheme that its technical problem that solves the utility model adopts is: T type tee union, include an import and two outlets, outlet is divided into direct export and side outlet, form the cavity passage of threeway between import and the outlet, it is characterized in that: the terminal throat structure that adopts in the joint of described inlet passage, throat structure dwindles the back with the passage bore and is connected with the passage of direct export, directly over described side outlet was positioned at, the passage of side outlet was connected with the joint of inlet passage.
In such scheme, adopt thin neck aperture to be connected between the passage of described side outlet and the passage of import.
In such scheme, adopt thin neck aperture to be connected between the passage of described direct export and the passage of import.
Principle of the present utility model is that the intersection in import and two outlets carries out the reducing design, forms the reflection mixed zone, can effectively improve lateral flow pressure in pressure-actuated pipeline flows, and the both sides rate of discharge is consistent.If according to using needs, the both sides rate of discharge needs ratio in accordance with regulations to carry out the branch timing, can reach designing requirement by the ratio of adjusting outlet latus rectum or sectional area.
The beneficial effects of the utility model are: can be in the supply air line of non-symmetry structure, effectively improve the pressure of lateral flow, the two ends rate of discharge is consistent or reaches the flow-rate ratio of designing requirement, and can be by adjusting local latus rectum size, the pressure at control outlet two ends and the ratio that flow-rate ratio reaches designing requirement, and can effectively simplify asymmetrical supply air line structure, reliable performance.

1. imports among the figure, 2. throat structure, 3. side outlet, 4. direct export.
Embodiment
Below in conjunction with embodiment, the utility model is further described:
T type tee union as depicted in figs. 1 and 2, include an import 1 and two outlets, outlet is divided into direct export 4 and side outlet 3, form the cavity passage of threeway between import 1 and the outlet, the terminal throat structure 2 that adopts in the joint of described import 1 passage, throat structure 2 dwindles the back with the passage bore and is connected with the passage of direct export 4, and directly over described side outlet 3 was positioned at, the passage of side outlet 3 was connected with the joint of import 1 passage.At two outlet sections of the inner chamber intersection of tee union, outlet must not directly communicate with import 1, and adopts the thin neck aperture of φ 3.2 to run through with it.When two thin neck latus rectums are identical, can guarantee that side outlet 3 is consistent with directly exported 4 flow; If change the latus rectum or the sectional area ratio of two narrow neck parts, then can control the two ends rate of discharge and distribute in proportion.As shown in Figure 2, the straight-through direction of threeway can require the certain corner of design according to Environmental Conditions, and is under the less situation of rotation angle, less to the influence of flow distribution.
Boundary dimension among the figure comprises that M18 * 1.5 screw threads, 60 ° of sealing cones, R8 sealing bulb, φ 10 latus rectums, 160 ° of turning angle equidimensions decide according to practical engineering application situation and requirement, to satisfy different flows, installation or connection request.
Claims (3)
1.T type tee union, include an import (1) and two outlets, outlet is divided into direct export (4) and side outlet (3), form the cavity passage of threeway between import (1) and the outlet, it is characterized in that: the terminal throat structure (2) that adopts in the joint of described import (1) passage, throat structure (2) dwindles the back with the passage bore and is connected with the passage of directly exported (4), directly over described side outlet (3) was positioned at, the passage of side outlet (3) was connected with the joint of import (1) passage.
