Case Details
Working Principle
The fire detection device is a pressure vessel filled with extinguishing agent. The fire detection tube is arranged along potential fire hazard points, and relies on its numerous detection points (linear) to detect when exposed to open flames or temperature shocks. The fire detection tube will burst at hot spots, causing the valve to actuate after the tube loses pressure, releasing the extinguishing agent and transmitting a fire signal.
System Advantages
The fire detection tube is made of a high molecular polymer, integrating flame retardancy, flexibility, and temperature sensitivity, capable of long-term leak resistance, with a maximum leakage rate of 10-5 mbar*l/s/m. It is a linear hose that is unaffected by dust, oil stains, and electromagnetic interference; the system operates independently without any external power supply and is not affected by power outages; the unique integrated valve design includes a ball valve to prevent damage and reduce the possibility of leakage; quick-connect fittings with dual sealing ring design ensure good sealing; high integration electromagnetic valve combination design provides customized solutions for customers, meeting the needs of different industries and application scenarios, with simple design and installation, and low maintenance costs.
