Why not let the fire drain valve property?

Communication with the property also involves their interests.

Drain valve is a kind of valve installed in pipeline system. The main function of the drain valve is to protect the flow safety of electric pipelines such as water heaters. When the water pressure is too high, it will automatically drain water and reduce the pipeline pressure. Therefore, the drain valve plays a considerable role in protecting the safety of electric appliances such as water heaters.

The diameter of drain valve varies from 150mm to 935 mm, which is mainly used for electric water heaters and air energy water heaters. It also has the functions of check valve and pressure relief valve. When the pressure in the inner container of the electric water heater is high, it can prevent the water entering the electric water heater from flowing backwards, discharge excess pressure, ensure the service life of the inner container and avoid the occurrence of bladder bursting accidents.
