クガスを、検知器に導入するプローブであつて、 先端部が容器・配管部の検査個所に近接した状
態で、吸込口１Ａからリークガスを吸い込み、ホ
ースを介して検知器３に該リークガスを導入する
スリーブ形の細管１と、 大径筒部２３の端面にリング形スリツト２４が
形成され、該リング形スリツト２４が検査個所に
対向するよう、小径端部２１を該細管１の先端部
に嵌着した二重壁スカート体２０とよりなり、 トレーサーガス１０とは異なるカーテン用ガス
２５ａを、該リング形スリツト２４から筒形に噴
流させて、該細管１の吸込口１Ａの周囲に、筒状
のガスカーテン２５を設けるよう構成したことを
特徴とするリーク検知用プローブ。[Scope of Claim for Utility Model Registration] A probe that introduces leak gas from a tracer gas sealed in a container or piping into a detector, with its tip close to the inspection point of the container or piping, at the suction port 1A. A ring-shaped slit 24 is formed on the end face of a sleeve-shaped thin tube 1 that sucks leak gas from the tube and introduces the leak gas into the detector 3 via a hose, and a large-diameter cylindrical portion 23. It consists of a double-walled skirt body 20 with a small diameter end 21 fitted to the tip of the thin tube 1 so as to face each other, and a curtain gas 25a different from the tracer gas 10 is passed through the ring-shaped slit 24 into a cylindrical shape. A leak detection probe characterized in that a cylindrical gas curtain 25 is provided around the suction port 1A of the thin tube 1 by a jet stream.
