To provide a drainage trap capable of continuously preventing a backflow of contaminated air and a growth of bacteria.SOLUTION: A drainage trap X comprises: a housing 5; and a division body 1 that divides an internal space of the housing 5 into a storage space 7 and a discharge space 8, wherein the division body 1 has a conductive valve body 15, a conductive valve seat 16 that supports the valve body 15, and a positive electrode 9A and a negative electrode 9B that are electrically connected to the valve seat 16, the positive electrode 9A and the negative electrode 9B are spaced apart from each other inside the storage space 7, electrical connection between the positive electrode 9A and the negative electrode 9B is cut off when pressure of liquid stored in the storage space 7 causes the valve body 15 to move away from the valve seat 16, and the positive electrode 9A and the negative electrode 9B are electrically connected via the valve body 15 and the valve seat 16 when the pressure drops and the valve body 15 comes into contact with the valve seat 16.SELECTED DRAWING: Figure 1
【課題】汚染空気の逆流と細菌の増殖とを持続的に防止できる排水トラップを提供する。【解決手段】排水トラップＸは、ハウジング５と、ハウジング５の内部空間を、貯留空間７と排出空間８とに仕切る区画体１と、を備え、区画体１は、導電性を有する弁体１５と、弁体１５を支持する導電性の弁座１６と、弁座１６に電気的に接続された正電極９Ａ及び負電極９Ｂと、を有しており、正電極９Ａ及び負電極９Ｂは、貯留空間７の内部で互いに離間して配置されており、貯留空間７に貯留された液体の圧力を受けて弁体１５が弁座１６から離間したときには、正電極９Ａと負電極９Ｂとの電気的な接続が遮断され、圧力が低下して弁体１５が弁座１６に当接したときには、弁体１５及び弁座１６を介して正電極９Ａと負電極９Ｂとが電気的に接続される。【選択図】図１
