Description
Technical Field
The utility model relates to a device of drainage pipe system especially relates to a drain pipe fitting.
Background
The development of cities can not be realized by water resources, and drainage pipelines are distributed in pipe networks of various cities and comprise resident drainage pipelines and industrial drainage pump drainage pipelines. When the drainage pump performs siphon drainage, harsh siphon noise can be generated; when the drainage pump is used for siphoning drainage, no water exists in the drainage pump, and once the drainage pump is electrified and operates again, the drainage pump generates harsh operation noise. These noises are different from industrial noises and traffic noises which are in contact with daily life, and belong to low-frequency noises. The low-frequency noise is characterized by slow attenuation, long sound wave and difficult processing because the diffracted wave energy easily bypasses the obstacle. These noises can seriously affect the work and rest of people and shorten the service life of the drainage pump. The flow of water in a common sewer is completely dependent on gravity difference, namely the principle of 'water flowing to low position' is completely dependent on self-flowing drainage. If excessive water flows through the outlet within a certain period of time and the outlet is blocked, the water pressure at the outlet is excessive, the pressure is released to the front end, and the sewage flows backwards. At present, a drainage pipe fitting matched with a drainage pump in the market does not have the anti-siphon function and does not have the function of preventing sewage from flowing backwards.
