Imported gas emergency shut-off solenoid valve
Imported gas solenoid valve is used in aerospace, shipbuilding, heavy industry, petrochemical industry, power equipment, industrial furnaces, boilers, gas pipe networks, gas treatment plants, gas stations, gas leakage alarm systems, safety protection systems, fire alarm systems , is widely used in the safety protection of flammable and explosive medium pipe networks in cities or factories. It can be quickly cut off when hidden dangers are discovered to prevent vicious accidents in time. Mainly used in the following occasions
Connected to combustible gas leakage monitoring instruments. When the instrument detects a leak of combustible gas, it will automatically and quickly close the main gas supply valve, cut off the supply of gas, and promptly prevent the occurrence of a vicious accident.
Connect to the extreme temperature or pressure safety controller of the thermal equipment. When the temperature or pressure at the detection point in the equipment exceeds the set limit value, the air supply valve will be automatically and quickly closed to stop the fuel supply.
Connected to the central fire alarm system of high-rise buildings. When a fire breaks out in the building, the gas supply in the building will be automatically cut off to prevent gas explosions.
Set up a B gas emergency shut-off valve in the gas supply pipeline network of a city or factory, which can be centrally controlled in the central control room and remotely controlled to emergency shut down the pipeline gas supply at the accident site.
Reliable technical performance, extremely low load loss, extremely high safety performance, excellent energy-saving performance and quick cut-off performance are the five major features of this series of products.

Principle of imported gas emergency cut-off solenoid valve
When the solenoid valve needs to be opened, pull up the handle with your hand, the solenoid valve opens and the coil is energized instantly When the delay time is no more than one second, the solenoid valve handle is reset and the solenoid valve is closed. When there is a power outage and the solenoid valve needs to be closed, press the manual button to close the solenoid valve. This valve must have a manual function. The special working principle can be energized for a long time when the power is turned on. Press the start button to open the valve. When an alarm occurs or there is a power outage, the valve closes. When the alarm is cleared or a call comes in, press the start button and the valve will open.
