The valve is designed as a normally open shut-off valve with a holding control mode. It remains open without power during normal operation and allows continuous gas flow.
When a leakage accident is detected, the alarm triggers and delivers an instantaneous DC pulse voltage to energize the coil. This rapidly drives the valve closed to cut off the gas source and enters a self-locking state.
The alarm's capacitor continuously releases a 3-second DC pulse voltage during a gas leak to energize the coil, ensuring secure valve closure and self-locking.
Yes. After closing, it can be manually opened via the reset device. If another shut-off signal is received later, it will automatically close again.
The system utilizes the combined interaction of instantaneous coil electromagnetic force, permanent magnetic force, and spring force to perform pulse drive, automatic closure, and manual self-holding functions.
The assembly includes nine key parts: Valve body, Diaphragm, Valve cover, Spring, Actuator, Reset Device, Dust cover, Moving iron core, and Sealing ring.
