DOOR STRUCTURE AND AIR-TIGHTNESS TESTING METHOD
To provide a door structure and an air-tightness testing method capable of improving measurement accuracy of air-tightness performance by reducing leakage of air from a part other than a gasket.SOLUTION: In the door structure 1, an annular gasket 2p is provided around an opening 2a, and an annular contacting part 28 contacting on the entire circumference of the gasket 2p is provided on the peripheral edge of the door body 20. An annular airtight chamber Ch is formed between the gasket 2p and the contacting part 28 along the gasket 2p. The airtight chamber Ch is provided with a pressure measuring port Hp and a flow measuring port Ha. In a state where the door body 20 is set at a sealed position, the airtightness performance of the door body 20 in the opening 2a can be measured by allowing a compressor C to flow gas into the airtight chamber Ch so that the pressure in the airtight chamber Ch measured by a pressure gauge P is constant for a predetermined time, and estimating the amount of gas leakage from a sealed portion of the opening 2a by the door body 20 based on the inflow amount measured by the flow meter F within the predetermined time.SELECTED DRAWING: Figure 3
【課題】パッキン以外からの空気の漏れを低減させることにより、気密性能の計測精度を向上させることのできる、扉構造及び気密試験方法を提供する。【解決手段】扉構造１は、開口部２ａの周囲に環状のパッキン２ｐが設けられ、扉本体２０の周縁部にパッキン２ｐの全周と当接する環状の当接部２８が設けられ、パッキン２ｐと当接部２８との間に、パッキン２ｐに沿って環状の気密室Ｃｈが形成され、気密室Ｃｈには圧力測定口Ｈｐ及び流量測定口Ｈａが設けられ、扉本体２０が密閉位置に配置された状態で、圧力計Ｐで測定する気密室Ｃｈ内の気圧が所定時間一定となるように、コンプレッサＣが気密室Ｃｈ内に気体を流入させ、所定時間内に流量計Ｆで測定した流入量に基づいて、扉本体２０による開口部２ａの密閉部分からの気体の漏れ量を推定することにより、開口部２ａにおける扉本体２０の気密性能が計測可能とされる。【選択図】図３
