ルブ本体と、弁室内に配されバルブの開閉を行う
ボールと、流通孔の弁室側開口に配されボールと
のシールを行うバルブシートとを有するボールバ
ルブにおいて、このバルブシートをＯリングとし
、流通孔の弁室側開口にＯリング受容溝を周設し
、Ｏリング受容溝近辺に塑性変形部を設け、Ｏリ
ング受容溝にＯリングを装着して塑性変形部を変
形させることにより、Ｏリングを押圧固定すると
共にボール方向への反発弾性が高まる形状にＯリ
ングを変形させてなることを特徴とするボールバ
ルブ。 A valve body equipped with a plurality of communication holes communicating through a valve chamber, a ball placed inside the valve chamber to open and close the valve, and a valve seat placed at the opening of the circulation hole on the valve chamber side to seal with the ball. In a ball valve having an O-ring, the valve seat is an O-ring, an O-ring receiving groove is provided around the opening of the flow hole on the valve chamber side, a plastically deformed portion is provided near the O-ring receiving groove, and an O-ring is provided in the O-ring receiving groove. A ball valve characterized in that the O-ring is deformed into a shape that presses and fixes the O-ring and increases rebound resilience toward the ball by attaching the O-ring and deforming the plastic deformation part.
