Fire Detection Tube Double sealing valve core check valve M14×1

The double-sealed valve core check valve for fire detection pipes is a critical control component specifically designed for fire detection pipe extinguishing systems. It integrates bidirectional sealing with unidirectional check functions, ensuring absolute tightness in the system's standby state and precise operational reliability when a fire occurs. The valve core uses special engineering materials and precise structural design, enabling it to work in coordination with fire detection pipes for rapid response to fire sources and efficient extinguishing. Core principle and function: The core of this valve lies in its unique 'double-seal' structure. The first seal maintains the internal pressure of the fire detection pipe under normal conditions, ensuring its sensitivity as a fire detection element; the second seal serves as a redundant safety measure, preventing accidental system malfunctions or medium leakage. In the event of a fire, when the fire detection pipe ruptures at its highest point of heat exposure and the internal pressure is released, the 'check' function of the valve core activates immediately. It quickly responds to pressure changes, accurately opens the main extinguishing agent container valve, ensures the extinguishing agent flows in the designated direction, effectively prevents backflow, and guarantees that the agent is delivered fully and quickly to the fire source. Outstanding reliability and applicability: Based on this integrated double-seal and check function design, the valve core acts as a simple yet reliable system 'switch.' It not only enhances the overall safety threshold of the extinguishing system, avoiding risks caused by single-seal failure, but also serves as an indispensable reliable control unit in various direct or indirect extinguishing systems.
