AIR TIGHTNESS MAINTENANCE MECHANISM FOR SHIELDING DOOR
To provide an air tightness maintenance mechanism for a shielding door for closing an opening when a blowout panel which is provided in a building of an atomic power plant, etc., is opened.SOLUTION: An air tightness maintenance mechanism comprises: a shielding door which is provided at an opening position that does not overlap with a blowout panel closing an opening of a building, slidable and movable to a closing position so as to close the opening after the blowout panel is opened; an upper frame part in which an upper part of the shielding door is suspended by a longitudinally movable arm and supported by an upper rail, and which includes an upper presser for pressing the shielding door coming to the closing position; a lower frame part in which a lower part of the shielding door is supported by a lower rail, and which includes a lower presser for pressing the shielding door coming to the closing position; a side frame part in which a side part of the shielding door is pressed, and which includes a side presser for pressing the shielding door coming to the closing position; and a sealant for sealing a clearance between the shielding door coming to the closing position and the opening.SELECTED DRAWING: Figure 1
【課題】原子力発電所の建屋などに設けたブローアウトパネルが開放されたときに開口部を塞ぐための遮蔽扉の気密維持機構を提供する。【解決手段】建屋の開口部を塞いでいるブローアウトパネルと重ならない開位置に設けられ、前記ブローアウトパネルが開放された後に前記開口部を塞ぐように閉位置までスライド移動可能な遮蔽扉と、前記遮蔽扉の上部を前後可動なアームで吊り下げると共に上レールで支持し、閉位置に来た前記遮蔽扉を押さえるための上押さえを有する上枠部と、前記遮蔽扉の下部を下レールで支持し、閉位置に来た前記遮蔽扉を押さえるための下押さえを有する下枠部と、前記遮蔽扉の側部を押さえ、閉位置に来た前記遮蔽扉を押さえるための側押さえを有する側枠部と、前記開口部を囲むように取り付けられ、閉位置に来た前記遮蔽扉と前記開口部の隙間を密閉するためのシール材と、を備える。【選択図】図１
