PIT GATE, PIT FACILITY, NUCLEAR POWER FACILITY, AND METHOD FOR INSTALLING PIT GATE
To provide a pit gate capable of being inserted smoothly and having sufficient seal performance, a pit facility, a nuclear facility, and a method for installing the pit gate.SOLUTION: A pit gate comprises: a gate body inserted between a pool part storing service water and a canal part connected to the pool part, and configured to change a circulation state of the service water; and a seal part 6 accommodated in a groove-like accommodation recess part formed in the gate body, and configured to seal the gap between the pool part and the gate body. The seal part 6 has: a low-rigidity part 10 relatively easy to deform due to a load based on water pressure from the pool part side; and a high-rigidity part 11 provided on the pool part side of the low-rigidity part, and relatively hard to deform due to the load.SELECTED DRAWING: Figure 5
【課題】より円滑に挿入することが可能で、かつ十分なシール性能を有するピットゲート、ピット設備、原子力施設、及びピットゲートの設置方法を提供する。【解決手段】ピットゲートは、用水を貯留するプール部及びプール部に接続されたキャナル部の間に挿入されることで、用水の流通状態を変化させるゲート本体と、ゲート本体に形成された溝状の収容凹部に収容され、プール部とゲート本体との間をシールするシール部６と、を備える。シール部６は、プール部側からの水圧に基づく荷重によって相対的に変形しやすい低剛性部１０と、低剛性部のプール部側に設けられ、荷重によって相対的に変形しにくい高剛性部１１と、を有する。【選択図】図５
