Explosion-Proof Floor Drains: Essential Specifications and Popular Models

The floor drain may seem like an unremarkable piece of hardware, but it is essential to install one in every household. Next, let's take a look at the specifications and models of explosion-proof floor drains.

Specifications and Models of Explosion-Proof Floor Drains

Common specifications include DN150, DN50, and DN100. The most common materials for floor drains are cast iron and stainless steel. The models for explosion-proof floor drains include FDI-X and FBFDDcr stainless steel explosion-proof floor drains. These devices are typically installed on drainage pipes outside the protective area and remain in a closed state most of the time. When sealed, they can prevent explosive shocks or toxic gases from entering the protective area through the pipes, thus providing a safety effect.

Installation Methods for Explosion-Proof Floor Drains

1. When installing an explosion-proof floor drain, it must be placed at the drainage pipe of the civil defense system. The explosion-proof floor drain should normally be in an open position to ensure smooth drainage. The cover for the civil defense floor drain can be lowered and sealed by rotating it counterclockwise, thereby directly preventing shock waves and toxic gases from entering the protective area and stopping backflow from underground water.

2. During installation, the floor drain body and the drainage pipe threads must be tightly screwed together before construction can proceed. The upper cover's top surface must be lower than the concrete surface by 5 to 10 millimeters.

3. After using the floor drain, it is necessary to regularly clean any debris and perform maintenance. This will not only help prevent blockage but also extend the lifespan of the floor drain.

4. A sealant strip must be used for the floor drain, and it should be inspected annually. Over time, rust may appear on the sealing surface, so it is essential to clean off any rust and dirt to ensure proper maintenance.
