Anti-backflow automatic intercepting pipeline
The invention discloses an anti-backflow automatic intercepting pipeline. The pipeline comprises a pipeline body, a pipeline annular cavity is formed in the pipeline body, a baffle device and a pressure sensing device which are opposite in the diameter direction of the pipeline annular cavity are arranged in the pipeline annular cavity, and the baffle device is in signal connection with the pressure sensing device; and the pipeline annular cavity is internally provided with a bulge with a gradient, the surface, right opposite to the forward flowing direction of fluid, of the bulge is a front surface, the surface, right opposite to the reverse flowing direction of the fluid, of the bulge is a back surface, and the pressure sensing device is arranged on the back surface of the bulge. The automatic intercepting pipeline has the advantages of being simple and understandable in structure, targeted, good in anti-backflow effect and high in automation degree, and when the pipeline is appliedto a sewage pipe network, the backflow of sewage and river water can be effectively avoided, and the phenomenon of treating the mixture between water with different water qualities is avoided.
本发明公开了一种防倒灌自动拦截管道，包括管道本体，所述管道本体内部设置有管道环腔，在所述管道环腔内安装有沿管道环腔直径方向相对的挡板装置和压力感应装置，挡板装置与压力感应装置信号连接；其中，所述管道环腔内设置具有坡度的凸起，凸起中同流体顺向流动方向正对的一面为正面，同流体逆向流动方向正对的一面为背面，所述压力感应装置安装在所述凸起的背面。该自动拦截管道具有结构简单易懂、有针对性、防倒灌效果好、自动化程度高的优点，将此应用于污水管网可以有效的避免污水及河水的倒灌，避免出现水质不同的水的混合的处理现象。
