Product Descriptions
The discharge point of rural domestic sewage is relatively scattered. If the drainage depends on gravity, the drainage pipe needs to be deeply buried and affected by the terrain and the structure. The construction is difficult and the cost is high, and the pipeline may have problems such as backflow and cracking. The vacuum negative pressure drainage system utilizes the principle of vacuum to generate high-speed airflow from the sewage by the difference in air pressure, and removes the sewage from the appliance.
Advantage
1	The drainage slope can be easily solved so that the sewage can be arbitrarily raised
2	The pipe diameter is small, the buried depth is shallow, and the construction is more convenient and quick
3	There is no spillover, it will not pollute the groundwater, and the environmental protection level is high
4	The overall airtightness is strong, there is no smell, and the cleanliness is high
5	The system is safe and self-checking. The principle of outdoor drainage is that the user's domestic sewage is discharged into the collector, and the water level in the collector reaches the set value to open the vacuum valve, and the water is pumped away by the vacuum station.
