しかし、従来の技術記載の方法では、ガス噴出状態での作業であるため、ガス 供給圧力の大幅な変動をきたすという問題点があった。 However, the method described in the related art has a problem in that the gas supply pressure fluctuates significantly because the operation is performed in a gas ejection state.
【０００５】 そこで、本考案は上記の問題を鑑み、バルブサービスチーズ１９のガス導管２ ０への取り付け作業時のガスの無噴出を目的としたものである。Therefore, in view of the above problems, the present invention aims to prevent the gas from being ejected when the valve service cheese 19 is attached to the gas conduit 20.
【０００６】[0006]
上記目的を達成するために、本考案は図１、２、３に示すような構成を成して いる。 In order to achieve the above object, the present invention has a configuration as shown in FIGS.
【０００７】 バッグ１２天側のビニール袋９に手挿入口１１を要した生ゴム板１０を接着し た。A raw rubber plate 10 requiring a manual insertion port 11 was adhered to a vinyl bag 9 on the top side of the bag 12.
【０００８】 バッグ１２の底部は、開口部２を大きくした環状中空ゴム１、ビニール板３の 形に沿った枠体４をそれぞれビニール板３に接着したAt the bottom of the bag 12, an annular hollow rubber 1 having an enlarged opening 2 and a frame body 4 conforming to the shape of a vinyl plate 3 are adhered to the vinyl plate 3, respectively.
【０００９】 又、ビニール板３の左右両側に、一定間隔毎にバンド掛け金具５を備えた鉄製 の押え板７を設け、押え板７はビニール板３を介し丸ビス６で鉄製の支え板８に 固定されるようにした。Further, iron holding plates 7 having band fittings 5 are provided on both left and right sides of the vinyl plate 3 at regular intervals, and the holding plate 7 is a support plate 8 made of iron with round screws 6 through the vinyl plate 3. It was fixed to.
【００１０】[0010]
上記、ガス導管工事用バッグを、ガス導管２０に装着すれば、ガスの無噴出化 を図ることができ、ガス供給圧力の大幅な変動を起こすことなくバルブサービス チーズ１９の仮締め作業を行うことができる。 If the above-mentioned bag for constructing the gas conduit is attached to the gas conduit 20, it is possible to prevent the gas from being ejected, and to temporarily tighten the valve service cheese 19 without causing a large fluctuation in the gas supply pressure. You can

本考案における実施例を図４に基づいて詳細に説明する。 An embodiment of the present invention will be described in detail with reference to FIG.
【００１２】 ガス導管２０の穿孔、切粉除去、穿孔部の盲止め作業後、本考案のバッグ１２ を盲止め部を通しガス導管２０に固定用ゴムバンド１７を用い装着する。After perforating the gas conduit 20, removing chips, and blinding the perforated part, the bag 12 of the present invention is attached to the gas conduit 20 using the fixing rubber band 17 through the blind part.
【００１３】 固定用バンド１７は図５、６に示すように、３つの尾錠１３と２つのゴムバン ド１４により構成されており、尾錠１３とゴムバンド１４はそれぞれボルト１５ 、ナット１６により固定、結合されている。As shown in FIGS. 5 and 6, the fixing band 17 is composed of three buckles 13 and two rubber bands 14, and the buckle 13 and the rubber band 14 are fixed and coupled by bolts 15 and nuts 16, respectively. Has been done.
【００１４】 上記、固定用ゴムバンド１７は、ガス導管管種により、本考案であるバッグ１ ２のバンド掛け金具５に尾錠１３の箇所を選択し装着するものである。The fixing rubber band 17 is to be attached to the band hooking fitting 5 of the bag 12 of the present invention by selecting the location of the buckle 13 depending on the type of gas conduit tube.
【００１５】 例えば、８０Ａ、１００Ａ、１５０Ａの管径のガス導管２０へのバッグ１２の 固定は、中央の尾錠１３と残りいづれか一方の尾錠１３を使用する２００Ａ、３ ００Ａの管径のガス導管２０へのバッグ１２の固定は、両端の尾錠１３により行 う。For example, the bag 12 is fixed to the gas conduit 20 having a tube diameter of 80A, 100A, 150A by using the central buckle 13 and either one of the remaining buckles 13 for the gas conduit 20 having a pipe diameter of 200A, 300A. The bag 12 is fixed to the bag by the buckles 13 at both ends.
【００１６】 バッグ１２をガス導管２０に装着後、手を手挿入口１１より腕部まで差し込み 気密を保持した状態で盲止めを取りはずし、装着したバッグ１２の中にあらかじ め挿入していたバルブサービスチーズ１９の分岐取り出し用孔１８への仮締め作 業を行う。After the bag 12 was attached to the gas conduit 20, the hand was inserted from the manual insertion port 11 to the arm and the blind stopper was removed while maintaining airtightness, and the valve was inserted into the attached bag 12 preliminarily. Temporary tightening work is performed on the branch take-out hole 18 of the service cheese 19.
【００１７】 その後、固定用ゴムバンド１７、バッグ１２をガス導管２０より除去し、バル ブサービスチーズ１９の本締め作業を行う。After that, the fixing rubber band 17 and the bag 12 are removed from the gas conduit 20, and the valve service cheese 19 is finally tightened.
【００１８】 尚、バッグ１２底部に接着している環状中空ゴム１、枠体４は、同じ肉厚であ り、材質は単気泡発泡スポンジゴムを使用しているが、弾力性および気密性を備 えていればこの限りではない。The annular hollow rubber 1 and the frame body 4 adhered to the bottom of the bag 12 have the same wall thickness and are made of single-cell foam sponge rubber, but they are elastic and airtight. This is not the case if it is equipped.
