The Ultimate Guide to Explosion-Proof Floor Drain Installation

What is an explosion-proof floor drain? What is the installation method for this type of drain? How does it differ from a regular floor drain?

Installation method of explosion-proof floor drain

First, pre-embed the drain using hot-dip galvanized steel. It should be embedded once and be cast in concrete synchronously with the construction. Next, it should be installed at the inner end of the drainage pipe outside the civil air defense area, and normally kept in a closed state. Finally, place the drain core in the valve chamber and rotate it clockwise about 60 degrees to maintain a sealed state.

What is an explosion-proof floor drain

This type of drain differs from regular drains and is designed for special occasions, primarily used in civil air defense areas. Compared to ordinary floor drains, its material has been upgraded; it usually features thickened castings and utilizes a water seal for sealing.

Additionally, the materials are generally eco-friendly, such as stainless steel or brass. Its impact resistance and corrosion resistance are quite high, with a high-temperature resistance of up to 80 degrees, while also accommodating large drainage volumes.

Differences between explosion-proof floor drains and regular floor drains

First and foremost, their purposes differ. The former is intended for civil air defense areas, such as basements, and serves to protect against shock waves generated by explosions. It is generally larger and heavier, with a round surface.

On the other hand, regular floor drains simply serve to drain water and provide sealing, typically used in bathrooms with a certain level of odor prevention.

The installation requires placement at the inner end of the drainage pipe outside the civil air defense area, which should normally be in a closed state. The drain core should be placed in the valve chamber, and turning it clockwise about 60 degrees will keep it sealed. Conversely, turning it counterclockwise by 60 degrees will open it, allowing it to function in shock wave defense and facilitating drainage and cleaning.

In summary：the information above outlines the installation method for explosion-proof floor drains, which need to be installed properly during concrete pouring. Due to the different locations of installation compared to regular drains, their materials and designs have also been upgraded and differ accordingly.
