Project supply of a Beijing fire Decoration Engineering Co., Ltd

On may18,2017, TJL valve was supplied by a fire Decoration Engineering Company in Beijing, including fire butterfly valve, fire gate valve, signal butterfly valve, check valve, etc

Butterfly valve mainly includes fire signal butterfly valve is an important component of automatic sprinkler system. It is a special valve used in the fire water supply system to monitor the closure and closure status by electric signal. It is mainly used for intercepting and monitoring the status of the main and branch pipes of the automatic sprinkler system. It can also be used for intercepting and monitoring the status of intercepting in common water supply and drainage systems and various fluid media (water, gas) transmission systems. The signal butterfly valve is a signal butterfly valve with wafer type central shaft plate seal. The sealing element adopts waterproof rubber, which has the advantages of simple structure and simple operation; Light weight, good sealing performance, flexible opening and closing; The opening and closing display position is accurate, reliable and moisture-proof.

2. service temperature: water medium 1~123 ℃; Other media -20~120 ℃.

3. switch capacity: DC24V 1A; AC220V 2A。

4. rated working pressure: 1.2MPa, 1.6Mpa.

5. nominal diameter: dn50-250


Fire valve is a kind of fire-fighting device and facility used to prevent fire. It is a necessary fire-fighting facility for the design of housing construction projects, so that in case of fire, it is easy to open and connect the fire truck, and then transmit and supply fire water to extinguish the fire in time.
