Core elements of an intermittent pressure flow drainage system are: pressure pipelines 1, set pressure drain valves 2 and automatic exhaust valves 5. First, the intermittent pressure flow drainage system collects waste water so that water level rises and energy is stored. No water is drained but air is released during the whole stage of collecting water. The set pressure drain valve opens automatically when the water level rises to a set pressure. Then the system enters into a pressure drainage stage when the flow is quickly discharged in a variable head pressure flow way. According to this system, pressure drainage is realized by use of gravitational potential energy of a flow without additional power device. The system has following beneficial effects: saving tubular product; reducing cost; generating electricity in some cases. Because of high flow velocity, water pipelines will not be blocked or clogged. The drainage system is energy-saving.
