Abstract

PURPOSE:To save labors for remaking a pipe, and also to execute an inspection of a narrow part, too, by pressurizing and expanding a pressure bag in a pipe by a liquid or a gas, adhering tightly it to the inside wall of the pipe, obstructing a flow of a gas, and detecting a defective part. CONSTITUTION:A pressure bag is moved by a moving spring wire 12 in a pipe 11. A pressure hose 13 is connected to a connecting port 5 and fixed by a hose band 4. Pressure is applied by a liquid or a gas from a moving type pressure bag adjusting valve 2, a pressure bag 16 is expanded through a discharge port 15, adhered tightly to the inside wall of the pipe, and a flow of a gas, etc. is obstructed. subsequently, an inspecting jig is set to an inspecting jig fitting valve 7, and an inspection is executed. As a result to the inspection, in case when abnormality is recognized, the inspection is repeated by moving the pressure bag, and if there is no abnormality at the time of the next inspection, it is known that a defective part exists in the moving range. In this way, a labors for remaking the pipe are saved, and also the inspection of a narrow part can be executed.

Description

【発明の詳細な説明】 配管（１１）内を移動用スプリングワイヤ（１２）にて

5) and secure with hose band (4).

移動式圧力袋調整バルブ（２）より、液体又は気体にて
加圧吐出口（１５）をへて圧力袋（１６）を膨張させ、
配管内壁に密着させ、ガス等の流動を阻止する。Inflate the pressure bag (16) with liquid or gas through the pressurized discharge port (15) from the mobile pressure bag adjustment valve (2),
Place it in close contact with the inner wall of the piping to prevent the flow of gas, etc.

配管の端末部に端末密閉治具をセットする。圧力袋調整
用バルブ（１）より、液体又は気体にて加圧する。Set the end sealing jig at the end of the piping. Pressurize with liquid or gas from the pressure bag adjustment valve (1).

吐出口（９）をへて圧力袋（８）を膨張させ、配管内壁
に密着させ、ガス等の流通を阻止する。The pressure bag (8) is inflated through the discharge port (9) and brought into close contact with the inner wall of the pipe, thereby blocking the flow of gas and the like.

検査をくり返す。検査の結果異常が認められなければ、
移動した範囲内に不良部分のある事が判明する。An inspection jig is set on the inspection jig mounting valve (7), and an inspection is performed by pressurization, depressurization, etc. If an abnormality is found as a result of the inspection, move the pressure bag (16) partially and
Repeat the test. If no abnormality is found as a result of the test,
It turns out that there is a defective part within the moved area.

従来の配管検査は、配管の両端を改造し、メクラブタ等
を施して検査を実施していたので、配管改造の手間がか
かり狭い場所での検査は、不可能であった。Conventional piping inspections have been carried out by modifying both ends of the piping and applying mechanical plugs, etc., which requires time and effort to modify the piping, making it impossible to conduct inspections in narrow spaces.

また、埋設配管の場合１ライン全体検査のため、不良配
管補修の場合ライン全体を引替える必要があった当発明
より、狭い場所の検査も可能になり、又不良場所が一定
の範囲内で、判明するので部分保守が可能になる。In addition, in the case of underground piping, one entire line is inspected, so when repairing defective piping, it was necessary to replace the entire line.This invention enables inspection of narrow areas, and allows inspection of defective areas within a certain range. Since it is clear, partial maintenance becomes possible.
