Claims (1)
ル部材を介して気密に摩擦保持するゲージポート
において、該ゲージポートは、前記挿入取付部と
シール部材との摩擦抵抗に打ち勝つて前記真空計
を外に押し出すのに必要な圧力よりも小さい真空
容器内圧力で弁孔を開動作するリリーフ弁を有し
ていることを特徴とするゲージポート。 In a gauge port that is fixed to a vacuum container and frictionally holds an insertion attachment portion of a vacuum gauge in an airtight manner via a sealing member, the gauge port overcomes the frictional resistance between the insertion attachment portion and the sealing member to remove the vacuum gauge. A gauge port characterized in that it has a relief valve that opens a valve hole at a pressure inside a vacuum container that is lower than the pressure necessary to push out the water.
