The negative pressure drainage system is a novel drainage system and has the advantages of large application potential, wide application occasions and superior engineering and technical economy. The negative pressure drainage system collects sewage distributed in a water collecting tank at the tail end of the tree-shaped negative pressure collecting pipe network to a negative pressure power center at the tail end of the system in a unified mode through negative pressure. Existing header tanks include a collection terminal, a suction pipe, an interface valve (also known as an interface valve), a pilot valve (solenoid valve, mechanical valve), and a level switch.
However, when the interface valve is in an open state, most of the water in the water suction pipe of the interface valve is full of pipe flow, the full pipe flow liquid is lack of air to drive and lose a large amount of kinetic energy, and as sewage enters the pipe, the kinetic energy is reduced, so that the suction speed is reduced, and the drainage efficiency is reduced. The products in the present stage mainly include two types: firstly, when the sewage reaches the starting liquid level, the interface valve is opened, the sewage is discharged into a pipe network, and when the liquid level in the collector drops to the closing liquid level, the valve is delayed to be closed, and partial air is sucked; secondly, some air release devices are arranged on the main pipe to release air section by section. The two modes can not completely ensure that the collector realizes continuous drainage, and the air inflow is uncontrollable, so that energy waste is easily caused, and the energy consumption is increased.
