【発明の詳細な説明】 イ 発明の目的 (1)産業上の利用分野 本発明は袋状のガス漏れ検出器を備えた小型ボンベに
関する。
The present invention relates to a small cylinder having a bag-shaped gas leak detector.

容積100cc以下の小型ボンベは絶対ガス収容量が少な
い。例えば、容積100ccのボンベの酵素収容量は18リッ
トルしかない。従って、ガス漏れは深刻な問題となる。
特に、緊急避難用として使用される酵素ボンベには3〜
5年の保証が必要であるので、簡易且つ安価なガス洩れ
検知手段が渇望されている。
Small cylinders with a capacity of 100 cc or less have a small absolute gas capacity. For example, a 100 cc cylinder has an enzyme capacity of only 18 liters. Therefore, gas leakage becomes a serious problem.
In particular, three to three cylinders are used for emergency evacuation.
Since a five-year warranty is required, there is a need for a simple and inexpensive gas leak detection means.

(2)従来技術とその問題点 従来は、ボンベを摂氏40度の温水に水没させ、泡の発

(2) Conventional technology and its problems Conventionally, gas leaks were detected by immersing a cylinder in warm water at 40 degrees Celsius and visually checking for bubbles. However, this method often overlooks a small amount of gas leakage.

また、ボンベの重量を図ることによりガス洩れを検知

ボンベから1分間に直径1mmの泡が1個漏出するとする
と、1カ月間の漏出体積Vm、並びに、1年間の漏出体積
Vy及び漏出重量Hyは、次のようになる。
There is also a method of detecting gas leakage by measuring the weight of the cylinder, but it is still difficult to find a small amount of gas leakage. Therefore, particularly important cylinders may be left for a few months and then re-weighed, but this may also lead to gas leaks that fail to be found. That is, for example, if one bubble having a diameter of 1 mm leaks from the enzyme cylinder in one minute, the leak volume Vm for one month and the leak volume for one year
Vy and leakage weight Hy are as follows.

Vm=4/3×π×0.053×60×24×30=22.6(cm3) Vy=22.6×12=271(cm3) Hy=32×0.271/22.4=0.38(g) しかも、実際にはこれより少量のガス洩れも存するか
らである。
Vm = 4/3 × π × 0.05 3 × 60 × 24 × 30 = 22.6 (cm 3) Vy = 22.6 × 12 = 271 (cm 3) Hy = 32 × 0.271 / 22.4 = 0.38 (g) Moreover, in practice, This is because there is a smaller amount of gas leakage.

そこで、容れ物全体を袋で覆ってしまう考え方が公開

The idea of covering the entire container with a bag is disclosed in Japanese Utility Model Publication No. 55-69069. in this case,
The metal can containing oil-impregnated paper is covered with a plastic bag, and if necessary, the inside of the bag is evacuated to cope with oil leakage from the can and damage to the can due to external pressure.

これで漏れの対象となっているのは非圧縮性の油であ

The target of the leak is now an incompressible oil, the leak is merely leaching, not being pushed out by the high pressure in the can. Thus, the leaked oil does not actively act to change the shape of the bag.

Also, since the bag is not required to be transparent and it is clear that the bag is made of a material that blocks oil penetration, if it is opaque, it is impossible to see the oil leak from outside, so this bag is It is merely a cover, and does not have a function as a detector that positively informs of leakage due to its own form change.

The present invention provides a small cylinder provided with a bag-shaped gas leak detector so that gas leakage from a cylinder containing high-pressure gas can be easily visually recognized from the outside by a form change such as expansion of the bag-shaped detector itself. The purpose is to:

(B) Configuration of the Invention (1) Means for Solving the Problems A small cylinder gas provided with a bag-shaped gas leakage detector according to the present invention comprises a bag-shaped detector made of a non-permeable resin film and a small cylinder. Have. The small cylinder is housed in the detector, and the inner wall of the detector is in close contact with the outer wall of the small cylinder by vacuum packing so as to be detachable and expandable from the outer wall due to a change in shape due to a leak gas pressure. The volume of the detector when expanded is larger than the volume of the small cylinder.

(2) Operation When gas leaks from the small cylinder, the gas does not leak out of the detector because the bag-shaped detector is sealed. Since the leaked gas has a pressure, a vacuum contact portion between the bag-shaped detector and the small cylinder is separated, and the bag-shaped detector itself changes its form and expands. Based on the degree of expansion, the presence and amount of gas leakage can be visually detected from the outside.

(3) Embodiment The vacuum-packed small cylinder 1 is composed of a bag-shaped detector 2 and a small cylinder 3 sealed in the detector 2. The bag-shaped detector 2 is preferably made of a transparent gas-impermeable resin film, and is adhesively sealed at a peripheral portion 2b. Of course, the term "gas-impermeable resin film" includes a small amount of gas permeation that can be ignored in relation to the purpose of gas use.

FIG. 5 shows that five small cylinders 3 are successively wrapped and
Here is an example of the unit.

The outer wall 3a of the small cylinder 3 is in close contact with the inner wall 2a of the bag-shaped detector 2 by vacuum packing (FIGS. 1 and 2).

Now, when gas leaks from the sealing plate part 3b, the cylinder outer wall
The close contact between 3a and the inner wall 2a of the bag-shaped detector 2 is released (FIG. 3). When the amount of leakage further increases, the close contact is completely released, and the bag-like detector itself changes its shape and expands as shown in FIG. The presence or absence and detection of gas leakage can be detected based on the capacity of the contact release portion and the degree of expansion.
