1.Static pressure test: ≥1MPa 2.Floor drain and perimeter test for anti-explosion pressure: 3.5MPa 3.Bottom test for anti-explosion pressure: 1.5MPa 4.Medium requirements: Water without corrosion and debris, water temperature 1~100°C
The explosion-proof floor drain is installed in the protection zone leading to the drain pipe outside the civil air protection zone, and is normally closed. Put the leaking core into the valve cavity and rotate it clockwise by about 60 degrees to completely close the lock (or vice versa, rotate 60 degrees counterclockwise). Explosion-proof floor drains can prevent explosion shock waves and other toxic gases from entering the shield body through the pipeline, which plays a safety protection role. In the wartime, when the area is infected, it is necessary to clean the explosion-proof floor drain, drain it, and rinse it.
