| description | PROBLEM TO BE SOLVED: To provide a high-pressure trunnion-type ball valve which is suitable for, in particular, a high-pressure fluid, makes a self-restraining force function by using the pressure of fluid flowing in the valve even if the valve is opened and closed at a high speed and at a high frequency, and can prevent leakage by sufficiently securing seal performance between a seat retainer and a ball by the self-restraining force, and a hydrogen station using the same.SOLUTION: A high-pressure trunnion-type ball valve has: a ball 10 which is arranged in a body 3 so as to be turnable; a seat retainer 12 which is seal-connected to the ball 10; and a spring member 13 for imparting a resilient force to the seal side of the seat retainer 12. A clearance CL is formed between the seat retainer 12 and the body 3 in a state that fluid pressure in a cavity C can be applied to a back face side of the seat retainer 12, and a communication hole 55 is formed at the ball 10 in a state that the fluid can circulate between an in-ball flow passage 10a and the cavity C.SELECTED DRAWING: Figure 1
【課題】特に高圧流体に適しており、高速且つ高頻度でバルブを開閉する場合でも、内部を流れる流体圧を利用して自緊力を機能させ、この自緊力によりシートリテーナとボールとのシール性を十分に確保して漏れを防止できる高圧用トラニオン型ボール弁およびこれを用いた水素ステーションを提供する。【解決手段】ボデー３内に回転自在に設けたボール１０と、このボール１０とシール接続するシートリテーナ１２と、このシートリテーナ１２をシール側に弾発力を付与するバネ部材１３とを有する。シートリテーナ１２とボデー３との間に、キャビティＣ内の流体圧がシートリテーナ１２の背面側に加わることが可能な状態でクリアランスＣＬが設けられ、且つ、ボール１０に、このボール内流路１０ａとキャビティＣとの間を流体が流通可能な状態で連通孔５５が設けられている。【選択図】図１ |
