The invention discloses an anti-backflow device for a municipal drainage closure pipe orifice. The anti-backflow device for the municipal drainage closure pipe orifice comprises a closure pipe, wherein the upper end of a pipe orifice of the closure pipe is fixedly connected with a mounting seat; the bottom of the mounting seat is provided with a vertical groove; the inside of the vertical groove is vertically and slidingly connected with a baffle plate; the bottom end side wall of the baffle plate is attached to the pipe orifice of the closure pipe; a first spring is fixedly connected betweenthe top of the baffle plate and the inner top wall of the vertical groove; the upper end of the baffle plate is vertically welded with a connecting rod; the connecting rod is positioned in the centerof the first spring; the upper end of the connecting rod penetrates and extends out of the mounting seat; and the middle of the baffle plate is provided with a limiting groove close to the edge. The anti-backflow device for the municipal drainage closure pipe orifice can automatically close the closure pipe when the water level in a drainage river is about to reach the height of the pipe orifice of the closure pipe, is high in transmission precision and convenient to reset, can prevent water in the drainage river from flowing backwards to affect the drainage efficiency of closure pipes in other directions, and is more beneficial to municipal drainage.
本发明公开了一种市政排水用截流管口防倒灌装置，包括截流管，所述截流管的管口上端固接有安装座，所述安装座的底部开设有一个竖槽，所述竖槽的内部竖直滑动连接有一块遮挡板，其中所述遮挡板的底端侧壁与截流管的管口贴合，所述遮挡板的顶部与竖槽的内顶壁间固定连接有第一弹簧，所述遮挡板的上端还竖直焊接有一根连接杆，所述连接杆位于第一弹簧的正中心且其上端贯穿延伸出安装座外部，所述遮挡板中间靠边缘处开设有一个限位槽。本发明可在排水河道内的水位即将到达截流管管口高度时自动封闭截流管，且传动精度较高，复位操作便捷，能够防止排水河道内的水倒灌影响其他方向截流管的排水效率，更加有利于市政排水。
