Self-draining and blow-off pipeline for underground sump
The invention provides an underground sump self-drainage blow-off pipeline which comprises a blow-off pump arranged in a sump, the blow-off pump is connected with a sewage pipeline, the sewage pipeline extends upwards from the sump to the ground, sewage at the tail end of the sewage pipeline is discharged to a sewage concentration pool, a check valve is installed on a lift section of the sewage pipeline, and a pressure gauge is arranged on the lift section on the lower side of the check valve. A water drain pipe is arranged on the lift section on the upper side of the check valve; the lower end of the water drain pipe extends to the sump; a quick opening and closing valve is arranged on the water drain pipe, the quick opening and closing valve and the sewage pump are both connected with the controller, and the quick opening and closing valve is in a closed state when the sewage pump works and is in an open state when the sewage pump stops. The pipeline is prevented from being soaked and corroded by sewage in the non-freezing season, installation is convenient, one-time investment is achieved, long-term resource consumption is not needed, maintenance is easy, and use is safe.
本发明提供一种地下集水坑自泄水排污管道，包括设置于集水坑中的排污泵，排污泵与污水管道相连，污水管道从集水坑向上延伸到地面，污水管道末端污水排放至污水集中池，污水管道扬程段安装有止回阀，止回阀下侧扬程段设有压力表，止回阀上侧扬程段设有泄水管，泄水管下端延伸至集水坑；泄水管上设有快速启闭阀，快速启闭阀、排污泵均与控制器相连，快速启闭阀在排污泵工作时为关闭状态，在排污泵停机时为打开状态。本发明避免在无冻结季节管道受到浸泡被污水腐蚀，安装方便，一次投入,不需要长期耗费资源，维护简单，使用安全。
