肉細管による分岐管継手に関する。[Detailed description of the invention] The present invention is applicable to hydraulic piping systems in automobiles, for example.
This invention relates to branch pipe joints made of thin-walled thin tubes used in fuel piping systems, oil supply piping systems, etc.

As shown in FIGS. 1 and 2, the means for joining and connecting the branch hole (branch A branch pipe d constituting a branch pipe is inserted into the branch hole c surrounded by the ring dyke b, and a brazing material is inserted at the joint surface between the branch pipe d and the ring dyke b. (Jointing welding material) e is brazed to join.

ら、実用上困難である。 However, the above-mentioned joining and connecting means for connecting the main pipe and the branch pipe cannot be used when there is no difference in diameter between the main pipe a and the branch pipe d as a branch pipe, or when the difference is small.
It is practically difficult to drill the branch hole c that together forms the ring embankment b from the viewpoint of preventing leakage due to hydraulic pressure and material strength.

る。 On the other hand, as shown in FIGS. 3 and 4,
As a means for joining and connecting the main pipe a and the branch pipe d, a branch hole c is bored in a part of the circumferential surface of the main pipe a, and the main pipe a, where the branch hole c is located, has a diameter that is approximately the same as that of the main pipe a. Joint saddle formed at the base of the branch pipe d
There is a method in which temporary welding is performed by spot welding so that d1 is clamped, and then the joint surfaces of the main pipe a and the joint saddle part d1 are joined by brazing with brazing material e.

の欠点がある。 However, during welding, ( 1 )
Not only is there a risk that the brazing material e may flow into the branch hole c and the opening of the branch hole may be closed or clogged;
Since the joint saddle d1 must be temporarily welded to the main pipe a for positioning by spot welding, the electrode and the main pipe or the thin branch pipe d will be shot and the side surface of the pipe will be burnt and a hole will be created. There is also a risk that the spot welds will be adversely affected by cracks, distortions, etc. due to local heating. Furthermore, (3) supervisor a
Since it is difficult to bring the joint saddle part d1 of the branch pipe d into close contact all around the circumference, poor brazing occurs.
Not only can it cause leakage at the joint, but also (4)
Since the bonding area is small, there is a risk of breakage from the bonding surface. If the position is shifted and temporary welding is performed, the joint saddle d1 of the branch pipe d will block the branch hole c, making it impossible to obtain the desired branch diameter. Therefore, there are disadvantages such as having to use a large amount of brazing material e.

岐管継手を提供するものである。 In order to solve the above-mentioned drawbacks, the present invention has been developed by fitting and caulking a short cylindrical body approximately perpendicularly to the main pipe in which a branch hole has been bored, and by attaching the short cylindrical body to the opening of the short cylindrical body that communicates with the branch hole. The branch pipe is fitted and fixed by joining these joint surfaces with brazing material, thereby eliminating clogging of the branch hole and improving the material strength of the joint surface. This provides a reliable branch pipe joint.

A short cylindrical body 3 is fitted into the main pipe 1, where the cylindrical body 3 is located, so as to be substantially perpendicular to the main pipe 1, and the lower end 3a of the short cylindrical body 3 is crimped with a tool such as pliers. It's becoming fixed. That is, a through hole 4 that fits into the main pipe 1 is bored in both side walls of the short cylindrical body 3,
The through hole 4 is fitted into the main pipe 1 in which the branch hole 2 is located substantially orthogonally.

is fitted so as to communicate with the branch hole 2, and the joint surface between the branch pipe 5 and the opening 3b and the lower end 3a of the short cylindrical body 3 are caulked.
There is a brazing material 6 between the joint surface and the main pipe 1.
a and 6b are fixed by heat welding. In other words, the above-mentioned both joint surfaces are the brazing materials 6a and 6b.
It is designed to be joined and fixed.

できる。 Therefore, unlike conventional joining and connecting means of this type, the present invention forms a ring bank b by burring a part of the main pipe, and also forms a joining saddle part d 1 at the base of the branch pipe d.
Moreover, it is no longer necessary to spot weld the joint saddle d1 for positioning, and a branch pipe joint that is reliable and reliable can be obtained.

ある。 As described above, according to the present invention, the branch hole 2 is bored in the main pipe 1, and the short cylinder 3 is fitted and caulked into the main pipe 1 in which the branch hole 2 is located, substantially perpendicularly. The branch pipe 5 is fitted into the opening 3b of the short cylindrical body 3, and these joint surfaces are joined and fixed with the brazing materials 6a and 6b, so (1), the short cylindrical body 3
Since the diameter of the branch hole 2 is larger than that of the main pipe 1, the distance between the branch hole 2 and the brazing material 6b to be brazed is increased, and excess brazing material tends to accumulate in the gap of the joint, making the brazing stronger. At the same time, the risk of reducing or blocking the branch hole 2 is eliminated (2), and by caulking the lower end 3a of the short cylindrical body 3, the adverse effects caused by spot welding are eliminated; (3) Furthermore, caulking increases the contact area between the main pipe 1 and the short cylindrical body 3, which not only makes the brazing work easier and prevents joint failures that may cause leaks, but also (4) allows the main pipe 1 to Since the structure is such that it is enclosed by the short cylindrical body 3, the strength of the joint portion is significantly strengthened.
