Product Structure and Function
1. Main Structure
The main body is made using an integrated stainless steel casting process, with no welding points. This ensures overall strength and sealing performance. The internal flow channels of the valve body have been optimized, reducing pressure loss and improving the efficiency of fire extinguishing agent flow.
2. Safety Valve System
An internal spring type safety valve is installed. When the system pressure exceeds the set value (2.8 MPa), it automatically releases pressure to protect the safety of the fire extinguisher cylinder. The safety valve uses corrosion-resistant springs and stainless steel valve seats to ensure long-term reliability.
3. Pressure Monitoring Interface
Standard 1/8-27NPT threaded pressure gauge interface, which can be connected to various standard pressure gauges, facilitating users to monitor the internal pressure status of the fire extinguisher in real time.
4. Inlet Tube Connection
The M16x1.5 metric thread design is suitable for most standard inlet tubes, ensuring the efficient extraction of fire extinguishing agent.
