ントロールできる。Conventional technology Conventionally, such a no-spout branch pipe connection device first attaches a short pipe for connecting the branch pipe to the existing pipe to which the branch pipe is to be connected using a clamp or the like, and then attaches a valve to the end of this short pipe. Then, attach a perforator to the end of this valve in an airtight state, open the valve, apply the cutter of the perforator to the existing piping through the flow path of this valve, and use the cutter to create a branch flow opening in the existing pipe. Then, the cutter of the perforator is retracted to close the valve, the perforator is removed, and the branch pipe is then connected. In this way, the branch pipe can be connected to the existing pipe in use without spouting the fluid flowing through the existing pipe to the outside. Of course, after the connection is completed, the flow of fluid to the branch pipe can be controlled by opening and closing the valve.

分岐管の接続が一層困難である。Problems to be solved by the invention In the conventional no-spout type branch pipe connection device as described above, first a short pipe is attached, a valve is attached to this, and a branch pipe is attached to this. Therefore, it is difficult or impossible to install a branch pipe in a place where there is a narrow space for arranging a branch pipe connection device, such as in domestic city gas piping. In addition, the use of screws, mechanical joints, clamps, etc. in piping for high-pressure gas conveyance is prohibited, and only connections by welding or flanges are permitted.
Connecting branch pipes is more difficult.

出分岐管接続装置を提供する。Means for Solving the Problems The present invention meets the requirements for the above-mentioned no-spout type branch pipe connection device, and the present invention connects a branch pipe to an existing pipe without spouting out the internal fluid when the pipe is in use. In order to do so, attach one end of the valve to the existing piping, attach a perforator to the other end of the valve in an airtight manner, and with the valve open, pass through the flow path of the valve and apply the cutter of the perforator to the existing piping to insert it into the existing piping. In the no-spout branch pipe connection device, which opens a branch flow port, then closes the valve by retracting the cutter of the perforator, removes the perforator, and connects the branch pipe to it, the above-mentioned valve is used. A pair of wings with a radius of curvature equal to the outside diameter of the existing pipe is formed at the end of the pipe to be connected to the existing pipe, and the wing part is connected to the existing pipe by welding, and a short tube for connecting the branch pipe is formed. To provide a no-spout branch pipe connection device, which connects a branch pipe to an existing pipe without using a pipe.
実施例
以下、図示の実施例について本考案を詳細に説
明する。Embodiments Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.
第１図において、１は既設配管、２は球形弁、
３はその弁子、４，５は流体流出入口、６は弁子
内の流路を示す。 In Figure 1, 1 is an existing pipe, 2 is a spherical valve,
Reference numeral 3 indicates the valve, 4 and 5 indicate a fluid inlet and outlet, and 6 indicates a flow path within the valve.
配管使用状態で流体供給無停止且つ無噴出で分
岐管を既設配管１に接続するために、弁２の一端
を既設配管にとりつけ、弁２の他端に穿孔機７を
気密にとりつけ、弁を開いた状態で弁の流体流出
入口４，５及び弁子３の流路６を通つて穿孔機の
カツタ８を既設配管１にあてて、これに分岐用流
通口９をあける。次に穿孔機のカツタ８を引込め
て、弁を閉じる。ここで既設配管１からの流体の
噴出はとめられる。 In order to connect the branch pipe to the existing piping 1 without stopping the fluid supply and without blowing out fluid while the piping is in use, one end of the valve 2 is attached to the existing piping, a perforator 7 is airtightly attached to the other end of the valve 2, and the valve is connected to the existing piping 1. In the open state, a cutter 8 of a punching machine is applied to the existing piping 1 through the fluid inlet and outlet ports 4 and 5 of the valve and the flow path 6 of the valve element 3, and a branching flow port 9 is opened therein. Next, the cutter 8 of the drilling machine is retracted and the valve is closed. At this point, the ejection of fluid from the existing pipe 1 is stopped.
次に、第２図に示すように、分岐管１０をとり
つければ、流体無噴出で分岐管を既設配管にとり
つけることができる。 Next, as shown in FIG. 2, by attaching the branch pipe 10, the branch pipe can be attached to the existing piping without jetting out fluid.
従来、この種の無噴出型分岐管接続装置におい
ては、先ず、既設配管にクランプによつて短管を
とりつけ、これに弁を接続し、更に分岐管を接続
していたので、分岐管の入口と既設配管との間に
相当大きいスペースが必要であつた。 Conventionally, in this type of no-spout type branch pipe connection device, first a short pipe was attached to the existing pipe with a clamp, a valve was connected to this, and then a branch pipe was connected. A considerably large space was required between the pipe and the existing piping.
しかし、本考案においては、弁２の既設配管に
接続すべき端部に、既設配管の外径に等しい曲率
半径をもつ一対の翼部１１，１１を形成し、この
翼部１１，１１を既設配管１に溶接１２によつて
接続する。 However, in the present invention, a pair of wing parts 11, 11 having a radius of curvature equal to the outer diameter of the existing pipe is formed at the end of the valve 2 to be connected to the existing pipe, and the wing parts 11, 11 are connected to the existing pipe. It is connected to the pipe 1 by welding 12.
従つて、既設配管１と分岐管１０の入口との間
隔Ｌは従来のものに比して極めて小さくすること
ができ、又、この翼部と既設配管１は溶接接続さ
れるので、高圧ガス搬送用パイプラインにおける
要求にも適合し、安全に高圧ガスを搬送できる。 Therefore, the distance L between the existing pipe 1 and the inlet of the branch pipe 10 can be made extremely small compared to the conventional one, and since the wing section and the existing pipe 1 are connected by welding, high-pressure gas transportation is possible. It also meets the requirements of industrial pipelines and can transport high-pressure gas safely.
