It is well known that the floor drain is a drainage device connected to the ground and the drainage pipe system. Then, what is the explosion-proof wave floor drain ? Let's take a look at the following.
Explosion-proof wave floor drain is a kind of floor drain in plumbing equipment, and it is a safety protection product. The explosion-proof wave floor drain is installed in the protection zone end on the drain pipe leading to the outside of the civil air protection zone. It is normally closed. The leakage core is placed in the valve cavity and rotated clockwise by about 60 degrees to completely close the lock. (Conversely, it can be rotated by rotating 60 degrees counterclockwise). When it is sealed, it can prevent explosion shock waves and other toxic gases from entering the shield through the pipeline, which plays a role in safety protection. When the area is exposed to fire during the war, the floor drain is opened and drained.
Explosion-proof wave floor drain is an anti-virus explosion-proof device made of cast iron and stainless steel. The connection method is threaded connection. Common calibers are DN50, DN65, DN80, DN100, DN150, DN200.
Main technical performance and requirements of explosion-proof wave floor drain:
Static pressure test: ≥1MPa
Anti-explosion pressure of floor drain and surrounding test: 3.5MPa
Bottom test anti-explosion pressure: 1.5MPa
Medium requirements: water without corrosion and debris, water temperature 1 ~ 100 ° C
Explosion-proof wave floor installation and use:
1. The product is installed in the drainage pipe of the civil air defense project. The floor drain is normally open to ensure normal drainage. In the wartime, the leakage cover is lowered, and the drain is closed after counterclockwise to prevent the shock wave, the poison gas enters the human defense zone, and the groundwater can be stopped.
2. When the floor drain is installed, the floor drain body and the lower pipe thread are tightened and then constructed. The top surface of the upper cover should be 5~10mm below the concrete level.
3. The floor drain should be cleaned regularly after installation.
4. The floor drain sealing strip is inspected every other year. It is found that the sealing surface of the floor drain body is rusted for long-term use, and should be derusted and maintained.
The above is the explosion-proof wave floor drain that Xiaobian accepts for everyone. I believe that everyone has a certain understanding of this, and more relevant information, please look forward to the tracking report of Xiaojiaju.com.
