The invention discloses an overflow valve. The overflow valve comprises a shell and a swing lever assembly, a water guide cavity is formed in the shell, a water inlet pipe and a water outlet pipe arearranged at the top and the bottom of the shell respectively, the bottom of the water inlet pipe extends into the water guide cavity, and a supporting piece is fixedly arranged on the side of the water inlet pipe. The swing lever assembly comprises a lever guide column hinged to the lower portion of the supporting piece, a water seal structure fixedly arranged at one end of the lever guide columnand a load fixedly arranged at the other end of the lever guide column. The water seal structure comprises a partition plate and an annular water baffle, a water storage area is defined by the annularwater baffle and the partition plate, and the bottom of the water inlet pipe extends into the water storage area. Under the normal condition, the swing lever assembly is in a closed state under the balance effect of the load, water in the water storage area plays a role in isolating air, when a drain valve drains water, outside air cannot enter a water outlet from the water inlet pipe, and the drainage speed is greatly increased through the siphonic effect; and when the pressure borne by the water seal structure is larger than the acting force of the load, the lever guide column rotates and opens the water inlet pipe to achieve overflowing.
本发明公开了一种溢流阀，包括壳体和摇摆杠杆组件，壳体内部开设有导水腔，壳体顶部和底部分别设有进水管和排水管，进水管底部伸入导水腔内。进水管侧边固设有支撑件。摇摆杠杆组件包括与支撑件下部相铰接的杠杆导柱、固设在杠杆导柱一端的水封结构以及固设在杠杆导柱另一端的负载。水封结构包括隔板和环状挡水板，环状挡水板与隔板之间合围形成一蓄水区，进水管底部伸入蓄水区内。正常情况下，摇摆杠杆组件在负载的平衡作用下处于关闭状态，蓄水区内的水起到隔离空气的作用，排水阀排水时，外界空气无法从进水管进入到排水口内，虹吸效应使得排水速度大幅提高；当水封结构受到的压力大于负载的作用力时，杠杆导柱旋转并打开进水管实现溢流。
