A1
Abstract:
An automatic draining apparatus for condensed water or leakage water in an aeration pipeline, comprising a water tank (1), a drainage and exhaust stand pipe (3), and a float valve (2). According to the apparatus, condensed water or leakage water is sprayed using pressurized air, and in the case that the condensed water or leakage water in an aeration pipeline is substantially drained, an outlet is substantially closed, only a very small amount of gas is allowed to flow out, and moreover, when accumulated water exists in the pipeline, the water outlet can be automatically opened wider to drain the accumulated water quickly. The water and sewage draining structure implements automatic water and sewage drainage, has a simple structure, features low costs, and can greatly improve the service life and the operation efficiency of an aeration system.
