在现代建筑与工业消防系统中，沟槽信号闸阀扮演着介质分流、合流及流向切换的关键角色。它专为消防管路系统设计，不仅具备传统闸阀的截断功能，更融入了智能信号反馈机制，是保障消防系统安全运行的“智慧中枢”。

In modern building and industrial fire protection systems, groove signal gate valves play a key role in medium diversion, merging, and flow direction switching. It is designed specifically for fire pipeline systems, not only with the traditional shut-off function of gate valves, but also integrated with intelligent signal feedback mechanisms, making it the "smart center" to ensure the safe operation of fire systems.

该阀门采用上装式结构设计，在高压、大口径工况下有效减少了阀体连接螺栓数量，增强了整体结构的可靠性。其阀板采用整体包胶工艺和弹性闸板结构，利用三元乙丙橡胶的弹性实现密封补偿，确保了极佳的截水效果。沟槽连接方式更是大幅简化了安装流程，提升了施工效率。

The valve adopts an upper mounted structural design, which effectively reduces the number of connecting bolts in the valve body under high pressure and large diameter working conditions, and enhances the reliability of the overall structure. The valve plate adopts integral rubber coating technology and elastic gate structure, utilizing the elasticity of EPDM rubber to achieve sealing compensation, ensuring excellent water interception effect. The groove connection method greatly simplifies the installation process and improves construction efficiency.

沟槽信号闸阀最核心的亮点在于其“信号”功能。阀门配备了限位控制开关，当阀板脱离全关闭位置时，能够通过触点向消防控制室输出电信号，实时反馈阀门的启闭状态。这一设计完美契合了《自动喷水灭火系统》的国家标准要求。它广泛应用于消防报警阀组两端或系统各支管入口，确保在火灾发生时，消防管网始终处于畅通无阻的备战状态，为生命与财产安全提供坚实保障。

The core highlight of the groove signal gate valve lies in its "signal" function. The valve is equipped with a limit control switch, which can output electrical signals to the fire control room through contacts when the valve plate is released from the fully closed position, providing real-time feedback on the valve's opening and closing status. This design perfectly meets the national standard requirements for automatic sprinkler fire extinguishing systems. It is widely used at both ends of the fire alarm valve group or at the entrance of each branch pipe of the system, ensuring that the fire pipe network is always in a smooth and unobstructed state of readiness in the event of a fire, providing a solid guarantee for the safety of life and property.
