本考案は１本の主配管に複数の分岐管を接続し
た多分岐管接手の改良に係り、特に口径の異なる
分岐管を設けやすくした多分岐管接手に関する。[Detailed description of the invention] [Field of industrial application] The present invention relates to the improvement of a multi-branch pipe joint that connects multiple branch pipes to one main pipe, and in particular, a multi-branch joint that makes it easier to install branch pipes with different diameters. Regarding branch pipe joints.
一般の建築物、プラントの配管設備、消火設備
等において、共通の流体源からくる１本の主配管
に幾つかの分岐管を接続して所要の個所へ分配す
る場合に多分岐管接手を必要とし、従来から種々
のものが用いられている。こゝに従来の多分岐管
接手の問題点を挙げると次の通りである。
In general buildings, plant piping equipment, fire extinguishing equipment, etc., multi-branch pipe joints are required when several branch pipes are connected to one main pipe coming from a common fluid source and distributed to the required locations. Various types have been used in the past. The problems with conventional multi-branch pipe joints are as follows.
(1) 主配管に分岐管を直接溶接したもの。(1) A branch pipe welded directly to the main pipe.
これは主配管の管壁に丸孔をあけて分岐管を
直角に溶接するもので、両管を突き合せ溶接す
るための開先加工が面倒であり、溶接作業に高
い技量を要し、これらが相待つてコスト高を招
く。 This method involves drilling a round hole in the wall of the main pipe and welding the branch pipe at right angles.The bevel processing required to butt weld the two pipes together is troublesome and requires a high level of skill in the welding process. This will lead to higher costs.
(2) フレア接手を用いるもの。(2) Those using flare joints.
これは主配管にフレア接手を溶接し、これに
分岐管を溶接するもので、フレア接手は高圧の
流体には使用できず、又主配管の管断面の約1/
２以下のものしか溶接できないため、太い分岐
管を設けようとすれば主配管も大径のものとな
るので、極めて不経済である。 In this method, a flare joint is welded to the main pipe, and a branch pipe is welded to this. Flare joints cannot be used for high-pressure fluids, and approximately 1/2 of the cross section of the main pipe is
Since it is possible to weld only 2 or less pipes, if a thick branch pipe is to be installed, the main pipe will also have to have a large diameter, which is extremely uneconomical.
(3) テイ接手とレデユーサを用いるもの。(3) Those using a tie joint and reducer.
これはテイ接手の側管にレデユーサを溶接
し、これに分岐管を溶接するので、溶接個所が
多数となり、分岐管のフランジの接触を避ける
ためテイ接手の主管にも中継管を溶接しなけれ
ばならない。このように溶接個所が多いからコ
スト高となるだけでなく、溶接に伴う歪みのた
め組立て精度が悪い。 Since the reducer is welded to the side pipe of the tie joint and the branch pipe is welded to this, there are many welding points, and in order to avoid contact between the flanges of the branch pipe, the relay pipe must also be welded to the main pipe of the tie joint. No. This large number of welding points not only increases cost, but also reduces assembly accuracy due to distortion caused by welding.
このほか従来の多分岐管接手は分岐管の口径変
更に対応できないため、設置作業中に設計変更が
あると始めから作り直さなければならないし、多
分岐管接手の主管をＵボルトで固定するものは回
転力に対して弱く、この主配管に支持具を溶接し
て固定するものは高圧流体の場合に安全性に欠け
る。本考案の目的はこのような従来技術の問題点
を解決した多分岐管接手を提供することにある。 In addition, conventional multi-branch pipe joints cannot accommodate changes in the diameter of the branch pipes, so if there is a design change during installation, they must be remade from scratch, and multi-branch pipe joints that fix the main pipe with U bolts It is weak against rotational force, and welding and fixing the support to the main pipe lacks safety when using high-pressure fluid. An object of the present invention is to provide a multi-branch pipe joint that solves the problems of the prior art.

In this invention, the main pipes of multiple T-tubes are lined up in a straight line and welded, and the branch pipes are screwed to the side pipes of each T-tube, so it is possible to assemble a multi-branch pipe joint using fewer parts and less welding. Therefore, it is possible to manufacture multi-branch joints with high precision at a low cost.For branch pipes with a smaller diameter than the main pipe, the threaded part is made thicker to the outside, making it easy to manufacture multi-branch pipe joints with different diameters. This has the effect of easily adapting to changes in the diameter of the branch pipe.
