1. Purpose:
Explosion-proof floor drains FBD (cast iron copper cover), FBFDCr (stainless steel) are suitable for the construction or reconstruction of various types of air defense basements such as diffusion rooms, decontamination rooms, anti-virus channels and other drainage floor drain devices that need to be washed. The simulated nuclear explosion test has reached five The anti-explosion requirements of the level civil air defense.
2. Main technical performance and requirements:
Working pressure difference 1.6mpa
Connection type Thread type (channel position) Straight-through flow direction unidirectional drive mode Hydraulic control purposes Sewage applicable medium Water pressure environment Atmospheric pressure medium requirements: medium temperature 80 (℃)
3. Installation and use:
1. The product is installed in the drainage pipeline of civil air defense engineering, and the floor drain is normally open to ensure normal drainage. In wartime, the floor drain leakage cover is lowered, and the drain port is closed after being tightened counterclockwise to prevent shock waves and poison gas from entering the air defense zone, and can prevent the groundwater from being poured back.
2. When installing the floor drain, the floor drain body and the sewer pipe screw are tightened before construction, and the top surface of the upper cover should be 5 ~ 10mm below the concrete horizontal plane.
3. After installing and using the floor drain, the sundries should be cleaned regularly.
4. Check the sealing tape of the floor drain every other year. If the sealing surface of the floor drain is rusted after long-term use, it should be derusted and maintained.
