Downstream pipeline damming alarm non-return drainage system and non-return drainage method
The invention relates to a downstream pipeline damming alarm non-return drainage system and non-return drainage method, and belongs to the technical field of building water supply and drainage. The system and the method solve the problem that backward flowing cannot be prevented when an existing gravity drainage system is applied to basement drainage. The downstream pipeline damming alarm non-return drainage system comprises a non-return valve outer pipe, a non-return valve, a monitoring assembly and a control system; the non-return valve is arranged in the non-return valve outer pipe, can beopened under the impact of upstream water flow or the control of external force, and can be closed under the control of self gravity or external force; the monitoring assembly is used for monitoring upstream and downstream water levels of the non-return valve; the control system comprises a controller and an alarm device, and the controller is connected with the monitoring assembly and used for receiving upstream and downstream water level signals monitored by the monitoring assembly and sending action instructions to the non-return valve and the alarm device according to the water level state. The system and the method can be applied to basement drainage, can give an alarm in time when a downstream pipeline is damped, and effectively prevents drainage backflow caused by the damped downstream pipeline.
本发明涉及一种下游管道壅水报警止回排水系统及止回排水方法，属于建筑给水排水技术领域，解决了现有重力排水系统应用在地下室排水，无法防止发生倒灌的问题。下游管道壅水报警止回排水系统包括止回阀外管、止回阀、监测组件和控制系统；止回阀设于止回阀外管内，止回阀能够在上游水流的冲击或外力控制下打开，且止回阀能够在自身重力或外力控制下闭合；监测组件用于监测止回阀的上下游水位；控制系统包括控制器和警报装置，控制器与监测组件连接，用于接收监测组件监测到的上下游水位信号，并根据水位状态对止回阀和警报装置发出动作指令。本发明能够应用于地下室排水，当下游管道发生壅水时能够及时报警，有效防止下游管道壅水发生排水倒灌。
