First, explosion-proof floor drain is good?
What is explosion-proof floor drain? The explosion-proof floor drain is installed at the end of the protection area on the drain pipe leading to the civil air defense protection area, which is usually closed. The leakage core is placed in the valve chamber and can be completely sealed and locked by rotating it clockwise for about 60 degrees (conversely, it can be withdrawn by rotating it counterclockwise for 60 degrees). When the explosion-proof floor drain is closed, it can prevent explosion impact and other toxic gases from entering the protective body through the pipeline. To play a role in safety protection, when the area is poisoned and needs to be cleaned during the war, the explosion-proof floor drain is opened, and the drainage can be washed.
What are its characteristics? Explosion-proof floor drain is divided into different materials, mainly cast iron and PVC, zinc alloy and ceramics, cast aluminum and stainless steel, brass and copper alloy and other materials, each material has obvious characteristics and advantages. In general, the explosion-proof floor drain belongs to the thickened casting body, which uses the water seal seal without mechanical principle. The sealing body is made of high-quality ABS, which is resistant to impact and high temperature 80°, so the sealing of the floor drain is very guaranteed.
Install an explosion-proof floor drain in the drainage pipe of a civil air defense project. Usually the floor drain is open to ensure normal drainage; During wartime, the floor drain cover will be lowered, and the drainage outlet will be closed after being tightened counterclockwise, to prevent shock wave and poison gas from entering the civil air defense project, and to prevent sewage backpouring. The water depth of the floor drain is 30mm, which can effectively control the odor leakage. From this, we found that it is still very good.
Second, what are the explosion-proof floor drain installation methods
The first step of installing explosion-proof floor drain: explosion-proof floor drain installation method: First find a good water slope to ensure that the water in each position can flow into, leave the tile on the side of the floor drain, measure the size of the gap and cut it to achieve a good effect. Cut the tile and lay it on the floor, such as the floor drain size 10cm X 10cm cut to 10.5cm suitable, leaving a little gap in the appropriate.
The second step of installing an explosion-proof floor drain: brush cement mud around the back of the floor drain to make it firmly bonded with the ground. Don’t brush too much. The center of the floor drain is opposite to the center of the drain pipe, put into the pipe, and press the floor drain level to be slightly lower than the tile surface. Remove excess cement and clean up the floor. Close the panel cover and install. After the cement dries, the floor drain core is installed, and the floor drain core can be removed and cleaned at any time.
The third step of installing explosion-proof floor drain: The installation of floor drain is more complex, and must be completed by professionals; Repair the drainage reservation hole, so that it is completely consistent with the floor drain bought back, because the real estate company in the handover of the drainage reservation hole is relatively large. Among them, the opening aperture of the floor drain grating should be controlled between 6-8mm, which can prevent the entry of dirt such as hair, sludge and sand. It should be grasped that the intake of multi-channel floor drains should not be too much.
Explosion-proof floor drain is one of many styles of floor drain. In people’s choice of floor drain, explosion-proof floor drain has gradually come closer to people’s vision, and has become the main choice for more and more people to buy floor drain. Through the introduction of the small series above, I believe that everyone has a comprehensive understanding and understanding of the installation of explosion-proof floor drains.
