【考案の詳細な説明】
真空容器等の欠陥を検査するため第１図に示すように容
器の被検査壁２に向けてヘリウムガン１からヘリウムガ
スを吐出し真空状態下とされた鉄壁の裏面で欠陥３から
漏出したヘリウムガスを検知することにより欠陥個所を
見いだすプルーブ法と呼ばれる検査方法がある。[Detailed description of the invention] In order to inspect defects in a vacuum container, etc., helium gas is discharged from a helium gun 1 toward the wall 2 to be inspected of the container, as shown in FIG. There is an inspection method called the probe method in which the defect location is found by detecting helium gas leaking from the defect 3.
しかし、第１図に示すように、ヘリウムガン１より吐出
されたヘリウムガスが抗散して検査部分より離れた位置
特にその上方の欠陥３Ａからもヘリウムガスが漏出し、
欠陥位置の発見が困難であった。However, as shown in FIG. 1, the helium gas discharged from the helium gun 1 scatters and leaks from the defect 3A located away from the inspection area, especially above it.
It was difficult to find the defect location.
本考案は上記不具合の解消のために提案されたものであ
り、以下、本考案を第２図の一実施例にもとづき説明す
る。The present invention was proposed to solve the above-mentioned problems, and the present invention will be explained below based on an embodiment of FIG. 2.
第２図において１０（ｄヘリウムガン、５はノズル管で
その基端はヘリウムガス源６に連接され、その先端５Ａ
よりヘリウムガスを被検査壁２に向けて吐出する。In Fig. 2, 10 (d) is a helium gun, 5 is a nozzle tube, the base end of which is connected to a helium gas source 6, and the tip 5A.
Helium gas is discharged toward the wall 2 to be inspected.
７Ｉｒｉ回収管でノズル管５の外周に口芯に配設され、
そのラッパ状に拡開した先端７Ａはノズル管５の先端５
Ａより突出し他端は吸引装置８に連接されている。A 7Iri recovery pipe is arranged around the outer periphery of the nozzle pipe 5 at the mouth core,
The trumpet-shaped expanded tip 7A is the tip 5 of the nozzle pipe 5.
The other end protrudes from A and is connected to the suction device 8.
９（ｒｉ握持部を示す。しかして、ノズル管５の先端５
Ａより吐出されたヘリウムガスは被検査壁２に当たった
後、回収管７へ吸引されるので周囲に拡散しない。9 (ri shows the gripping part. Therefore, the tip 5 of the nozzle pipe 5
After the helium gas discharged from A hits the wall 2 to be inspected, it is sucked into the recovery tube 7, so that it does not diffuse into the surroundings.
したがって、従来、困難であった欠陥位置を容易に発見
できる。Therefore, the defect position, which has been difficult to find in the past, can be easily found.
なお、回収管７の先端７Ａを被検査壁２に近接せしめて
吸引装置８を作動させずにヘリウムガスを吐出すれば局
部的に高圧のヘリウムガス雰囲気を作ることができ、よ
り高精度な検査が可能となる。Note that if the tip 7A of the recovery tube 7 is brought close to the wall 2 to be inspected and helium gas is discharged without operating the suction device 8, a locally high-pressure helium gas atmosphere can be created, allowing for more accurate inspection. becomes possible.
