Frequently Asked Questions (FAQ)
What is the default state of the valve during normal operation?
The valve is normally open and operates in a holding control mode, remaining open without power during normal operations.
How does the valve close automatically during a gas leak?
Upon detecting a leak, the alarm system triggers and provides a DC pulse voltage to the solenoid valve. The coil is energized, driving the valve to close rapidly and cut off the gas supply.
Does the valve reopen automatically after the signal stops?
No, once the valve closes, it enters a self-locking state. It must be manually opened to reset and resume operation.
What type of electrical signal triggers the valve closure?
The valve is closed by a continuous 3-second DC pulse voltage released from the alarm's capacitor to energize the coil.
What forces are used to operate the valve?
The system achieves automatic closing, pulse drive, and manual opening self-holding functions through the interaction of instantaneous electromagnetic force, permanent magnetic force, and spring force.
What are the primary internal components of this valve?
Key components include the valve body, diaphragm, valve cover, spring, actuator, reset device, dust cover, moving iron core, and sealing ring.
