| description | To provide a high-pressure trunnion type ball valve which is adapted to, in particular, a high-pressure fluid, can make the high-pressure fluid flow by being opened and closed in a state that a thrust load at an operation of a valve body is suppressed, is secured in operability by maintaining low-torque performance even if the number of times of rotational motions of the valve is increased, and to provide a hydrogen station.SOLUTION: A high-pressure trunnion type ball valve has a ball 22 rotatably arranged in a body 21 in a state that a seat retainer 30 is sealed and connected to both sides, and a stem 23 connected to the ball 22, and transmitting a rotation force. A thrust bearing 24 for reducing rotation torque by receiving a thrust load from the ball 22 side is attached to the stem 23, and the thrust bearing 24 is arranged in a non-contact region R with respect to a high-pressure fluid flowing in the body 21, and containing hydrogen.SELECTED DRAWING: Figure 2
【課題】特に高圧流体に適しており、弁体操作時のスラスト荷重を抑えた状態でバルブを開閉して高圧流体を流すことができ、バルブの回転動作回数が増加した場合にも、低トルク性を維持して操作性を確保した高圧用トラニオン型ボール弁並びに水素ステーションを提供する。【解決手段】両側にシートリテーナ３０がシール接続された状態でボデー２１内に回転自在に設けられたボール２２と、このボール２２に接続されて回転力を伝達するステム２３とを有する。ステム２３にボール２２側からのスラスト荷重を受けて回転トルクを低減するスラストベアリング２４が装着され、このスラストベアリング２４がボデー２１内を流れる水素を含有する高圧流体に対して非接触領域Ｒに配置されている。【選択図】 図２ |
