The utility model relates to a hood type ventilation pipe, which is used for discharging harmful and poisonous gases in a drainage pipeline to meet the sanitary requirements. Ventilation tube to the reservoir, water tank and a drainage pipe full of fresh air, can reduce the corrosion of metal pipes, and prolong the service life.
Reservoir, water tank should be set up two or more ventilation tube to improve the capacity of the drainage system, (for a small example: when an intravenous drip bottle liquid will flow down, must be inserted a snorkel, one end through the atmosphere, through the gap between the end surface, and the bottom of the bottle to prevent the formation of negative pressure, ensure smooth drainage pipe to prevent the formation of stagnant water, odor), reduce the pressure fluctuation, the protection of water, to prevent water damage. Cover type ventilation tube can be water vapor and harmful gas reservoir and water tank discharge, built-in gauze gauze can effectively prevent mildew disease, insects and dust into the water damage.
