Description

Gas blocking device for pipeline

The invention relates to a drainage pipe, in particular to a pipe gas blocking device.

Drainage of ordinary household condensate, such as condensate, washing water, or bath water from an air conditioner, is drained directly or temporarily into a temporary storage tank using a drainage pipe, and then it is continuously discharged to the sewer outside the house. Such a discharge method easily causes the biogas in the sewer to infiltrate into the house along the drainage pipe, causing the smell of biogas to permeate the house and affecting the living quality. If the biogas seeps home along the drainage pipe to use an air conditioner, the biogas contains sulfides that will chemically react with the cold air condensing copper pipes. In the long term, the condensing copper pipes will become black and rusty. More serious, it will also cause the condensing copper tube to rupture and leak the refrigerant, which will affect the efficiency of the cold air.
