The invention provides a household sewage pipeline check valve. The household sewage pipeline check valve is installed at the joint of a sewage discharging main pipe and a sewage discharging unit andhas the functions of observing a sewage discharging pipeline, serving as an access hole, preventing sewage from reversely returning and being smooth without blocking. The household sewage pipeline check valve is characterized in that a check dredging valve is arranged at the joint of the sewage discharging main pipe and the sewage discharging unit, wherein a dredging pipe in the check dredging valve is arranged behind a branch opening of the sewage discharging main pipe, a dredging pipe cover is exposed on the ground of the sewage discharging unit, and after the dredging pipe cover is taken away, a dredging rod can enter the sewage discharging main pipe from the dredging pipe to dredge.
本发明提供一种家用污水管道逆止阀，它安装在排污总管与排污单元的交接处，具有排污管道观察、充当检修口、阻止污水逆向返回、流畅无阻挡的功能。家用污水管道逆止阀的特征是：逆止疏浚阀设在排污总管与排污单元的交接处，逆止疏浚阀中疏浚管设在排污总管分支口的后面，疏浚管盖露在排污单元的地面上，拿掉疏浚管盖以后，疏通杆能从疏浚管进入到排污总管之中疏浚。
