The two center lines vertical setting each other of described arm and described straight tube, the described arm that the center of described straight tube is communicated with is one to the arc pipe that radially bends extension.
Two center lines of described arm and described straight tube arrange altogether on same vertical plane, and the described arm that the center of described straight tube is communicated with is an arc pipe extending to axial bending.
Two center lines of described arm and described straight tube are the setting that intersects vertically, and the described arm that the center of described straight tube is communicated with is a nanubrium extending vertically upward.
Described in each, three-way pipe is that cast inblock is one-body molded to be processed, and described in each, the end face of flange is connected exterior edge face with limiting block described in each and is smooth plane.
Each described flange is provided with the annular groove of a placement seal ring.
The utility model is owing to taking above technological scheme, it has the following advantages: 1, three-way pipe of the present utility model connects supervisor because employing flexibly connects head, the stress that therefore can discharge this place of three-way pipe is concentrated, and reduces and sews and follow-up maintenance work, improves vehicle operating safety.2, three-way pipe of the present utility model connects because employing flexibly connects head and connects braking system, therefore makes the pipeline of the braking system connecting not only have larger error compensation ability, can also alleviate the difficulty of this place's assembling simultaneously.3, three-way pipe of the present utility model, because the head that flexibly connects that adopts lighter weight connects, therefore can reduce this place's Brake pipe in vehicle operating process and lift fastening pressure.The utility model can be widely used in different kinds of railways lorry and manufacture in braking system.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Embodiment one:
As shown in Figure 1, the present embodiment is the two center lines vertically disposed three-way pipe 10 each other of arm 11 and straight tube 12, the arm 11 that straight tube 12 center is communicated with is one to the arc pipe that radially bends extension, the external part of arm 11 is connected with a flange 13 with attachment hole, the two ends of straight tube 12 are symmetrically arranged with a joint socket 14, the end edge of each joint socket 14 is circular-arc changeover joint 15, so that the installation of seal ring, be respectively arranged with the limiting block 16 of an annular flange flange at the middle part of each side straight tube 12, flexibly connect for assembling and location.
Embodiment two:
As shown in Figure 2, the present embodiment is the three-way pipe 20 that two center lines of arm 21 and straight tube 22 arrange altogether on same vertical plane, the arm 21 that straight tube 22 center is communicated with is an arc pipe extending to axial bending, and arranging all of the joint socket 24 on flange 23 and straight tube 22 that the external part of arm 21 connects and changeover joint 25, limiting block 26 is all identical with joint socket 14 on embodiment one flange 13 and straight tube 12 and changeover joint 15, limiting block 16.Also can set up one at the end face center of flange 23 for placing the annular groove 27 of seal ring, to increase the sealing of its connection.
Embodiment three:
As shown in Figure 3, the present embodiment is that arm 31 is the three-way pipe 30 that intersects vertically and arrange with two center lines of straight tube 32, the arm 31 that straight tube 32 center is communicated with is a nanubrium extending vertically upward, the joint socket 34 on flange 33 and straight tube 32 that the external part of arm 31 connects and changeover joint 35, limiting block 36 arrange all with embodiment one flange 13 and and straight tube 12 on joint socket 14 and changeover joint 15, limiting block 16 all identical.
