【発明の詳細な説明】
鋼板を溶接して継ぎ合わせることにより建造し上火型タ
ンクや鋼管を溶接して継ぎ合わせたラインパイプなどに

査する検査方法の１つとしＣ，アンモニアリークテスト
が知られている。[Detailed Description of the Invention] Inspection for inspecting for the presence of cracks and leak holes in welded parts of top-fired tanks constructed by welding and joining steel plates, line pipes made by welding and joining steel pipes, etc. One of the known methods is the ammonia leak test.
この検査方法は、溶接部の表面にブロム−フェノール・
ブルー試薬（Ｂ ＰＢ）を塗布し、裏面に′ンモこアガ
スを充満させ、リーク穴が存在したときにそのリーク穴
を通過したアンモニアガスがＢＰＢと反応して変色する
からこの変色した斑点を１ｉ１１認することによりリー
ク穴の有無を判定するものである。This inspection method uses bromine-phenol on the surface of the weld.
Apply blue reagent (B PB) and fill the back side with ammonia gas, and when there is a leak hole, the ammonia gas that has passed through the leak hole will react with BPB and change color. The presence or absence of a leak hole is determined by checking the leakage hole.
しかし、このようなリーク穴を検査する新しい手法を開
発してもその手法を試行するためのリーク穴が容易に得
られないという問題があった。However, even if a new method for inspecting such leak holes was developed, there was a problem in that leak holes for testing the method could not be easily obtained.
そこで、この発明の模擬リーク穴素子は、このような問
題点を解決し、いつでも試行用リーク穴が得られるよう
に考えられたものであって１次に図面に基づいて詳細に
説明する。Therefore, the simulated leak hole element of the present invention was designed to solve these problems and enable trial leak holes to be obtained at any time, and will first be described in detail with reference to the drawings.
第１図に示すように、ガラス管を加熱して内径が１−１
０ミクロン程度になるまで引伸ばすことにより細管を形
成し、この細管を一定長さに切断したのち、直ちに両端
を加熱溶融して封じ、ガラス＃Ｉ／ｌｔ−片（１）を作
る。As shown in Figure 1, a glass tube is heated to reduce the inner diameter to 1-1.
A thin tube is formed by stretching it to about 0 micron, and after cutting this thin tube to a certain length, both ends are immediately sealed by heating and melting to make a glass #I/lt- piece (1).
次に、鉄板（２）のような板材にテーパー状の穴（３）
をあけたものを用意し、この穴（３）にガラス細管片（
１）を挿通して、穴（３）とガラス証管片（１）との隙
１１■をエポキシ樹脂などの接着剤（４）で固定する。Next, make a tapered hole (3) in a plate material like an iron plate (2).
Prepare a hole with a hole (3) and insert a piece of glass tube (
1) and fix the gap 11■ between the hole (3) and the glass tube piece (1) with an adhesive (4) such as epoxy resin.
また、第２図に示すように、鉄板（２）に一様な穴径の
穴（５）をあけ、一方ガラス細管片（１）に、内径がガ

）の穴（５）に挿通して放置すると合成物のゴム類のチ
ューブ（６）の長さが収縮するとともに、外径が太くな
るので穴（５）とガラス細管片（１）との隙間が合成物
のゴム類で充満されることによって固定してもよい。In addition, as shown in Figure 2, holes (5) with a uniform diameter are drilled in the iron plate (2), and holes (5) with a uniform diameter are drilled in the glass tube piece (1), while the inner diameter is larger than the outer diameter of the glass tube piece (1). After fitting a thin synthetic rubber tube (6) and pulling this synthetic rubber tube (6) to narrow the outer diameter, the iron plate (2
) If you insert it into the hole (5) and leave it for a while, the length of the synthetic rubber tube (6) will shrink and the outer diameter will increase, so the gap between the hole (5) and the glass thin tube piece (1) will shrink. may be fixed by being filled with a synthetic rubber.
このように、鉄板（２）にガラス細管片（１）を挿通し
て構成した模擬リーク穴素子を使用する際には、ガラス
細管片（１）の根もとにやすりで疵をつけ折欠くことに
より、鉄板の表裏間を貫通したリーク穴を得ることがで
きる。In this way, when using a simulated leak hole element constructed by inserting a glass thin tube piece (1) into an iron plate (2), scratch the base of the glass thin tube piece (1) with a file and break it. By doing so, it is possible to obtain a leak hole that penetrates between the front and back of the iron plate.
以にで説明したように、この発明の模擬リーク穴素子が
構成されているから、リーク穴の内径が極めて小さなも
のまで作ることができ、また、使用するまで封じられて
いるから油膜やｐ！Ｉ埃で穴づまりを生ずることがない
など実用ヒ優れた効果を発揮することができる。As explained above, because of the structure of the simulated leak hole element of the present invention, it is possible to make a leak hole with an extremely small inner diameter, and since it is sealed until it is used, there will be no oil film or p! It can exhibit excellent practical effects such as no clogging of holes due to dust.
