To provide a drainage trap which can smoothly perform drainage of water by keeping loss of blowing air to the minimum during drainage, and which enables reduction in size by making the length short in the direction in which a fluid flows in a valve chamber.SOLUTION: A drainage trap 10 is interposed horizontally in a drain passage. The drainage trap 10 includes a pipe-shaped body 11 having a valve chamber 13, and a valve body 12 installed in the valve chamber 13. The valve chamber 13 includes: a partition wall part 17 provided substantially perpendicular with respect to the pipe-shaped body 11; and a center through-hole 18 formed at the partition wall part 17. The valve body 12 includes: a pivot 21 which passes a substantial center point O2 of the center through-hole 18, in which both end parts are installed at corresponding places on an inner peripheral surface of the center through-hole 18 respectively, and which is mounted substantially horizontally with respect to the pipe-shaped body 11; and an opening/closing valve 20 which is mounted in the center through-hole 18 so as to rotate in the direction in which a fluid flows with the pivot 21 as a fulcrum, and which closes the center through-hole 18 when a drain pressure equal to or greater than a predetermined value is not applied.SELECTED DRAWING: Figure 2
【課題】排水時に、送風空気の損失を最小限に保ち、水の排出を円滑に行うことができるとともに、弁室における流体が流れる方向の長さを短くして小型化を可能にする排水用トラップを提供する。【解決手段】排水用トラップ１０は、排水通路中に横置きで介装される。排水用トラップ１０は、弁室１３を有する管状本体１１と、弁室１３内に設置された弁体１２を備えている。弁室１３は、管状本体１１に対し略垂直に設けられ隔壁部１７と、隔壁部１７に形成されている中央貫通孔１８と、を備えている。弁体１２は、中央貫通孔１８の略中心Ｏ２を通り、両端部を中央貫通孔１８の内周面の対向する箇所に各々設置させて、管状本体１１に対し略水平に取り付けられている枢軸２１と、中央貫通孔１８内に枢軸２１を支点として流体が流れる方向に回転自在に取り付けられ、所定以上の排水圧がかかっていないときに中央貫通孔１８を閉じる開閉弁２０と、を備えている。【選択図】図２
