試験槽（１）は、底部にガス導入口（２１）を有し、天井部に排気口（１０）を有し、撹拌機（２２）を有する。導入ガス濃度測定口（３２）はガス導入口（２１）付近に、槽内ガス濃度測定口（１１）は排気口（１０）付近に設けられている。図９は、従来の腐食試験装置のガス導入部の説明図である。従来の腐食試験装置においては、腐食ガスは、試験槽（１）の底面に設けた一箇所のガス導入口（２１）から試験槽内へ導入する。 The test tank (1) has a gas inlet (21) at the bottom, an exhaust (10) at the ceiling, and a stirrer (22). The introduction gas concentration measurement port (32) is provided near the gas introduction port (21), and the in-tank gas concentration measurement port (11) is provided near the exhaust port (10). FIG. 9 is an explanatory view of a gas introduction part of a conventional corrosion test apparatus. In the conventional corrosion test apparatus, the corrosive gas is introduced into the test tank from one gas inlet (21) provided on the bottom surface of the test tank (1).
ガス定量希釈装置（２）は、試験槽（１）に附設されており、ボンベ（１２）からガスを取り入れ、空気供給機（１５）の空気で希釈して一定濃度にした腐食ガスとして試験槽（１）に供給する。 The gas quantitative dilution device (2) is attached to the test tank (1), and takes the gas from the cylinder (12) and dilutes it with the air of the air supply machine (15) as a corrosive gas having a constant concentration. Supply to (1).
試験槽（１）には、ガス濃度測定器（１６）が附設されており、槽内のガス濃度を測定することができる。ガス濃度測定器（１６）は、三方電磁弁（２０）を介して、導入ガス濃度測定口（３２）、及び槽内ガス濃度測定口（１１）に接続されている。ガス濃度測定器（１６）は、試験槽に導入されるガスの濃度と試験槽内のガスの濃度を測定できる。 A gas concentration measuring device (16) is attached to the test tank (1), and the gas concentration in the tank can be measured. The gas concentration measuring device (16) is connected to the introduction gas concentration measuring port (32) and the in-tank gas concentration measuring port (11) via a three-way solenoid valve (20). The gas concentration measuring device (16) can measure the concentration of the gas introduced into the test tank and the concentration of the gas in the test tank.
排気処理装置（３）は、試験槽（１）に附設されている。排気口（１０）から排気されたガスを排ガス用除湿器（１７）で除湿し、排気処理装置（３）で処理して無害化し、排気送風機（１８）で外部に排出する。腐食試験中は、常に排気送風機（１８）で試験槽（１）を吸引し、試験槽（１）の圧力を大気圧より−２００Ｐａ低い値に設定している。 The exhaust treatment device (3) is attached to the test tank (1).

During the corrosion test, the test tank (1) is always sucked by the exhaust blower (18), and the pressure of the test tank (1) is set to a value lower than the atmospheric pressure by −200 Pa.
シール部（１３）のシールは、耐食性パッキンであり、上蓋のシール部への締め付けは、締め付けハンドル（３３）によって行っていた。その締め付けは通常人力で行っており、毎回の締め付け力が一定であることの保障はなく、締め付け箇所が複数ある場合には、それぞれの箇所の締め付け力を一致させることは困難であった。また、槽内圧力は管理されていなかった。

腐食ガスは、ガス導入口（２１）から分配管（９）のガス吐出孔（２８）を通って槽内全体に供給される。ガス導入口（２１）、ガス分配管（９）のガス吐出孔（２８）がガス導入手段である。ガスは、ガス分配管（９）のガス吐出孔（２８）によって、試験槽内に均一に配分される。ガス導入部には、ガス吐出孔（２８）が２以上あいたガス分配管（９）が設けられている。 The corrosive gas is supplied from the gas inlet (21) to the entire tank through the gas discharge hole (28) of the distribution pipe (9). The gas introduction port (21) and the gas discharge hole (28) of the gas distribution pipe (9) are gas introduction means. The gas is uniformly distributed in the test chamber by the gas discharge holes (28) of the gas distribution pipe (9). The gas introduction part is provided with a gas distribution pipe (9) having two or more gas discharge holes (28).
図６は、本発明の腐食試験装置の実施例２の試験槽内のガス分配管の説明図である。図７は、本発明の腐食試験装置の実施例２のガス導入部の説明図である。本発明の腐食試験装置の実施例２では、試験槽中央から四方に伸びたガス分配管（９）の先がそれぞれ二方向に分かれて細管となり、その細管に３箇所のガス吐出孔（２８）が開いている。ガスは、ガス分配管（９）によって、試験槽内に均一に配分される。 FIG. 6 is an explanatory view of a gas distribution pipe in the test tank of Example 2 of the corrosion test apparatus of the present invention. FIG. 7 is an explanatory view of a gas introduction part of Example 2 of the corrosion test apparatus of the present invention. In Example 2 of the corrosion test apparatus of the present invention, the tip of the gas distribution pipe (9) extending in all directions from the center of the test tank is divided into two directions to form a narrow tube, and three gas discharge holes (28) are formed in the narrow tube. Is open. The gas is evenly distributed in the test chamber by the gas distribution pipe (9).
よって、本発明の実施例２の腐食試験装置によれば、試験槽のガス漏洩を防止し、試験槽内の腐食ガス成分比を一定に保ち、かつ試験槽内のガス濃度分布を一定に保つことができ、ひいては安全かつ再現性に優れた試験を行うことができる。 Therefore, according to the corrosion test apparatus of Example 2 of the present invention, gas leakage of the test tank is prevented, the ratio of the corrosive gas components in the test tank is kept constant, and the gas concentration distribution in the test tank is kept constant. As a result, a test that is safe and excellent in reproducibility can be performed.
