Paimen is a one-way valve installed at the outlet of the drainage pipe along the river. When the tide level of the river is higher than the outlet pipe and the pressure is greater than the pressure inside the pipe, the Paimen panel automatically closes to prevent the river tide from flowing back into the drainage pipe. According to customer requirements, flange pipe connections, wall connections, and pump station pipelines can be selected.
Steel side doors are important equipment for ensuring the safe operation of pumping stations. Their function in pumping stations is to cut off flow and prevent water backflow during shutdown. They are mainly used for flood control and drainage, agricultural irrigation, urban water supply and drainage, cross basin water transfer, as well as water supply and distribution for various large-scale enterprises.
