Description
【0001】[0001]
本考案は、主として水道用管路の管内流体を一時的に遮断する止水装置に使用 する止水装置用バッグに関するものである。 The present invention mainly relates to a bag for a water stop device used for a water stop device that temporarily shuts off a fluid in a water pipe.
【0002】[0002]
従来、止水装置及びそのバッグは、先に本願考案者らが提案した特開平3−1 77697号や実開平4−22691号が存在する。 しかしながら、上記のバッグは以下に述べるような問題を有していた。 すなわち、図3は上記のバッグの使用状態を示すもので、管路の管21に取付 けた止水装置22内から管21に穿設したバッグ挿通用孔23を通して管21内 に収縮状態にあるバッグ24を配設し、バッグ24に連結したゴム製ホ−ス25 から空気又は水をバッグ24内に送入してバッグ24を膨張させて行くと、管2 1内を流れている水の圧力によるバッグ24の水流抵抗が増大して管21の下流 側にバッグ24が強く押され、このためホ−ス25が強い曲げ力と引張力を受け て図示のように、ホ−ス25の先端部に設けた口金26との境界部分27で急激 な曲がりを生じて損傷し、切断に至るという問題を有していた。 Conventionally, as a water stop device and its bag, there are JP-A-3-177697 and JP-A-4-22691 proposed by the inventors of the present application. However, the above bag has the following problems. That is, FIG. 3 shows a usage state of the above-mentioned bag, and is in a contracted state inside the pipe 21 through the bag insertion hole 23 formed in the pipe 21 from the water stop device 22 attached to the pipe 21 of the pipe line. When the bag 24 is arranged, and air or water is fed into the bag 24 from the rubber hose 25 connected to the bag 24 to inflate the bag 24, the water flowing in the pipe 21 is filled. The water flow resistance of the bag 24 due to the pressure is increased, and the bag 24 is strongly pushed to the downstream side of the pipe 21. Therefore, the hose 25 receives a strong bending force and a tensile force, and as shown in the figure, the hose 25 There is a problem that a sharp bend is generated at the boundary portion 27 with the mouthpiece 26 provided at the tip end portion, which is damaged and leads to cutting.
【0003】[0003]
そこで本考案は、バッグ主体が管内で膨張されて行く際管の水圧により強く押 されても、バッグ主体に接続したホ−スが口金との境界部分で急激な曲がりによ り損傷、切断することを防止する止水装置用バッグを提供し、もって上記従来技 術の問題を解決しようとするものである。 Therefore, according to the present invention, even if the bag main body is strongly pressed by the water pressure of the pipe when the bag main body is inflated in the pipe, the hose connected to the bag main body is damaged and cut by the sharp bend at the boundary with the mouthpiece. The present invention aims to provide a bag for a water shut-off device that prevents such a problem, and thus solve the above-mentioned problems of the conventional technology.

すなわち、本考案は、止水用バッグ主体の取付口部に可撓性を有するホ−スを 接続し、該ホ−スの先端部に口金を被設したものにおいて、ホ−ス折曲防止管の 一端部を前記口金の内端部に嵌着し、該ホ−ス折曲防止管の他端部に形成した喇 叭管状部を前記ホ−スの外周側に配置したことを特徴とする止水装置用バッグを 要旨とするものである。 That is, according to the present invention, a hose having flexibility is connected to a mounting opening mainly for a waterproof bag, and a mouthpiece is provided at the tip of the hose to prevent hose bending. One end of the pipe is fitted to the inner end of the mouthpiece, and a conical tubular portion formed at the other end of the hose bending prevention pipe is arranged on the outer peripheral side of the hose. The main idea is a water-stop device bag.

このようにした止水装置用バッグにあっては、使用時に管路の管に取付けた止 水装置内から管に穿設したバッグ挿通用孔を通して管内に収縮状態にあるバッグ 主体を配設すると共にホ−ス折曲防止管の喇叭管状部を管内に臨ませ、ホ−スか ら空気又は水をバッグ主体内に送入してバッグ主体を膨張させて行くと、管内圧 力によるバッグ主体の水流抵抗が増大してバッグ主体が管の下流側に強く押され 、このためホ−スが強い曲げ力と引張力を受けるが、ホ−ス折曲防止管の喇叭管 状部に沿って緩やかに曲がり、急激な曲がりが防止される。 In such a water blocking device bag, when in use, the bag main body in a contracted state is arranged in the pipe from the water blocking device attached to the pipe of the pipeline through the bag insertion hole formed in the pipe. At the same time, when the hose bending prevention tube has a tubular portion facing the inside of the tube and air or water is sent from the hose into the bag main body to expand the bag main body, the bag main body is compressed by the pressure inside the bag. The water flow resistance of the bag increases and the bag main body is strongly pushed to the downstream side of the pipe, and therefore the hose receives strong bending force and tensile force. Bend gently to prevent sharp bends.

次に本考案の一実施例を図1、図2に基いて説明すると、1はバッグ主体であ って、ゴム等の気密性及び柔軟性を有し、一端に取付口部2を備えている。3は ゴム等の可撓性を有するホ−スであり、該ホ−ス3の一端部がバッグ主体の取付 口部2に挿嵌されている。ホ−ス3の他方先端部外周には口金4が嵌着され、口 金4の外端部には接続用ナット5が回転可能に付設されている。 6は一端方に喇叭管状部7を有する金属製のホ−ス折曲防止管であって、該ホ −ス折曲防止管6の他端部が口金4の内端部外周側に嵌着され、喇叭管状部7が ホ−ス3の外周側に配置されている。 An embodiment of the present invention will now be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a bag as a main body, which has airtightness and flexibility of rubber or the like and has a mounting opening 2 at one end. There is. 3 is a flexible hose made of rubber or the like, and one end of the hose 3 is inserted and fitted into the mounting opening 2 mainly of the bag. A mouthpiece 4 is fitted around the other end of the hose 3, and a connecting nut 5 is rotatably attached to the outer end of the mouthpiece 4. Reference numeral 6 is a metal hose bending prevention tube having a concavity tubular portion 7 at one end, and the other end of the hose bending prevention tube 6 is fitted to the outer peripheral side of the inner end of the mouthpiece 4. The concentric tubular portion 7 is arranged on the outer peripheral side of the hose 3.
【0007】 このようにした本例の止水装置用バッグにあっては、止水個所への使用時に、 図2に示すように、管路の管8に取付けた止水装置9内から管8に穿設したバッ グ挿通用孔10を通して管8内に収縮状態にあるバッグ主体1を配設すると共に ホ−ス折曲防止管の喇叭管状部7を管8内に臨ませ、ホ−ス3から空気又は水を バッグ主体1内に送入してバッグ主体1を膨張させて行くと、管8内圧力による バッグ主体1の水流抵抗が増大してバッグ主体1が管8の下流側に強く押され、 このためホ−ス3が口金4との境界部分11で強い曲げ力と引張力を受けるがホ −ス折曲防止管の喇叭管状部7に沿って緩やかに曲がり、急激な曲がりが防止さ れる。In the water shut-off device bag of the present embodiment as described above, when the water shut-off bag is used at a water shut-off point, as shown in FIG. The bag main body 1 in a contracted state is disposed in the tube 8 through the bag insertion hole 10 formed in the tube 8, and the concentric tubular portion 7 of the hose bending prevention tube is exposed to the tube 8. When air or water is fed into the bag main body 1 from the gas 3 to expand the bag main body 1, the water flow resistance of the bag main body 1 due to the pressure inside the pipe 8 increases, and the bag main body 1 is located downstream of the pipe 8. Therefore, the hose 3 receives a strong bending force and a tensile force at the boundary portion 11 with the mouthpiece 4, but the hose 3 bends gently along the concentric tubular portion 7 of the hose anti-folding pipe and suddenly bends. Bending is prevented.

以上説明したように本考案においては、止水使用時、バッグ主体が管内で膨張 される際に管の水圧により押され、バッグ主体に接続したホ−スが強い曲げ力と 引張力を受けてもホ−ス折曲防止管の喇叭管状部に沿って緩やかに曲がり、ホ− スの急激な曲がりによる損傷や切断が防止できる。 As described above, in the present invention, when the bag main body is inflated in the pipe, the hose connected to the bag main body receives a strong bending force and a tensile force when the bag main body is expanded by the water pressure of the pipe. Also, the hose bends gently along the concavity tubular portion of the hose anti-bending tube, and damage and cutting due to the abrupt bend of the hose can be prevented.
