の内圧を測定する方法に関するものである。The present invention relates to a method for measuring the internal pressure of a compressed gas container, and particularly to a method for measuring the internal pressure of a compressed gas container from the outside without opening the valve of the compressed gas container.
高圧のガスを使用する場合に、その供給方法としては二
通りの方法がある。即ち配管による供給と圧縮ガス容器
による供給である。When using high-pressure gas, there are two methods for supplying it. That is, supply by piping and supply by compressed gas container.
この圧縮ガス容器による供給方法を採用した場合には、
使用に当たってはガスの残量を把握しておくことが必要

定は非常に面倒な作業のため、簡単且つ安全に行える圧
縮ガス容器の内圧測定方法が要望されている。When this supply method using compressed gas containers is adopted,
When using a compressed gas container, it is necessary to know the remaining amount of gas, and this is generally determined by measuring the internal pressure of the compressed gas container. However, since measuring the internal pressure of a compressed gas container is a very troublesome task, there is a need for a method for measuring the internal pressure of a compressed gas container that can be performed simply and safely.
従来の圧縮ガス容器の内圧測定方法は、第3図に示すよ
うにその都度、圧縮ガス容器4に配管7と圧力計8を接
続し、バルブ9を開いて圧縮ガスを送気して測定する方
法である。The conventional method for measuring the internal pressure of a compressed gas container is to connect a pipe 7 and a pressure gauge 8 to the compressed gas container 4 each time, open the valve 9, and supply compressed gas to measure the pressure, as shown in Fig. 3. It's a method.
以上説明の従来の圧縮ガス容器の内圧測定方法で問題と

は、圧力針に送気した後の配管内の残留ガスの処理が厄
介なことである。The problem with the conventional method of measuring the internal pressure of a compressed gas container as described above is not only that it is troublesome to connect the pressure gauge, but also that the pressure needle is difficult to connect when the compressed gas is flammable or toxic. It is difficult to deal with residual gas in the piping after air is supplied to the pipe.
本発明は以上のような状況から圧縮ガス容器のバルブを
開かないで外部から圧縮ガス容器の内圧を簡単且つ安全
に測定する方法の提供を目的としたものである。In view of the above-mentioned circumstances, the present invention aims to provide a method for easily and safely measuring the internal pressure of a compressed gas container from the outside without opening the valve of the compressed gas container.

解決される。The above problem can be solved by the present invention, which measures the internal pressure of the compressed gas container by providing an annular elastic band with a built-in strain gauge around the compressed gas container, and detecting the deformation of the compressed gas container using the strain gauge and pressure measuring device. This problem is solved by a method for measuring the internal pressure of a compressed gas container.

ス容器の内圧を測定することが可能となる。That is, in the present invention, if the correlation between the internal pressure of the compressed gas container and the change in the circumference of the compressed gas container is determined in advance,
If the change in the circumference of the compressed gas container due to the internal pressure of the container is measured using a strain gauge and pressure measuring device built into the annular elastic band fitted to the compressed gas container, the internal pressure of the compressed gas container can be determined from the above correlation. It becomes possible to do so.
以下第1図〜第2図について本発明の一実施例を説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
第1図に本発明による一実施例の要部を示す。FIG. 1 shows the main parts of an embodiment according to the present invention.

される。1, the compressed gas container 4 is fitted with the annular elastic band 1 shown in FIG. . A connector 3 provided on the annular elastic band 1 and a pressure measuring device 5 are connected by a cable, and a compressed gas container 4
The change in the circumferential length of the compressed gas container 4 with respect to the internal pressure is detected and converted, and the pressure measuring device 5 shows the internal pressure of the compressed gas container 4.
標準的な圧縮ガス容器4の形状は、外径232n、肉厚

、
2+++B t
となり、1TlIBIP+r+jの値を代入すると、P

△r ”’0.08mm となる。The shape of the standard compressed gas container 4 is a thin-walled cylinder with an outer diameter of 232n and a wall thickness of 6.3mm, so the increase in radius due to internal pressure is 2+++B t , and when the value of 1TlIBIP+r+j is substituted, P
If it is 100kg/cJ, then △r is 0.08mm.
従って圧縮ガス容器の外周は、
内圧Okg / dで728.85m、100kg/a
aで729.35mであり、その差は0.5Onとなる

検出可能である。Therefore, the outer circumference of the compressed gas container is 728.85 m and 100 kg/a at an internal pressure of Okg/d.
a is 729.35 m, and the difference is 0.5 On, so for 1 kg / ctA, it is 0.005 m,
Detectable.
圧力測定器5の電源としては太陽電池6が内蔵されてい
るので、電源の設けられていない圧縮ガス容器4の保管
場所においても、内圧測定には何等支障は無い。Since the solar cell 6 is built-in as a power source for the pressure measuring device 5, there is no problem in measuring the internal pressure even in a storage location where the compressed gas container 4 is not provided with a power source.
このように歪ゲージ2を内蔵した輪状弾性帯1を圧縮ガ
ス容器4に嵌めておけば、圧力測定器5と歪ゲージ2を
コタネクタ3にて接続するだけで、配管7や圧力計8を
接続してバルブ9を開く作業をせずに、圧縮ガス容器の
内圧の測定が可能である。If the annular elastic band 1 with the built-in strain gauge 2 is fitted into the compressed gas container 4 in this way, the pressure measuring device 5 and the strain gauge 2 can be connected by simply connecting them with the connector 3, and then the piping 7 and the pressure gauge 8 can be connected. The internal pressure of the compressed gas container can be measured without having to open the valve 9.
また、圧縮ガス容器4の運搬等の取り扱いに際して、こ
の輪状弾性帯1により容器と容器が直接に接触すること
が無いので、衝撃に対する容器の保護に有効である。Further, when the compressed gas container 4 is transported or handled, the annular elastic band 1 prevents the containers from coming into direct contact with each other, which is effective in protecting the container against impact.
