The invention discloses a negative pressure siphon drainage system and a working method.The negative pressure siphon drainage system comprises a water storage container, a drainage pipe, a plugging piece, a valve rod, a lower floating body, a hard connecting rod and an upper floating body, a siphon drainage opening is formed in the inner side of the water storage container, and the drainage pipe is arranged on the outer side of the water storage container and communicated with the siphon drainage opening; one end of the valve rod is connected with the plugging piece, the lower floating body is arranged on the valve rod, the upper floating body is arranged above the lower floating body, the top end of the hard connecting rod is connected with the upper floating body, and the bottom end of the hard connecting rod is connected with the valve rod or the lower floating body; the water storage container is provided with a first critical liquid level completely submerging the lower floating body and a second critical liquid level starting to submerge the upper floating body. Internal and external power sources and air source driving are not needed, opening and closing of the valve are controlled by combining downward pressure, upward buoyancy and the torque of negative pressure suction in a negative pressure pipe network, and the opening and closing mode is endogenous mechanical driving.
本发明公开了一种负压虹吸排水系统及其工作方法，该负压虹吸排水系统包括储水容器、排水管、封堵件、阀杆、下浮体、硬质连接杆和上浮体，储水容器的内侧设有虹吸排水口，排水管设置在储水容器外侧并与虹吸排水口连通，封堵件转动设置在虹吸排水口上，阀杆的一端与封堵件连接，下浮体设置在阀杆上，上浮体设置在下浮体的上方，硬质连接杆的顶端与上浮体相连，硬质连接杆的底端与阀杆或下浮体相连；储水容器设有完全淹没下浮体的第一临界液位和开始淹没上浮体的第二临界液位。本发明无需内外部电源、气源驱动，其结合了下压力、上浮力以及负压管网内负压吸力的力矩控制阀门的开关，其开关方式为内源性机械驱动。
