Gas emergency shut-off valve
It is a new safety supporting device for gas pipeline engineering. It is mainly used in the following situations: 1. 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. ② Connect with the limit temperature (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 is automatically and quickly closed to stop the fuel supply. ③Connect with the central fire alarm system of high-rise buildings. When a fire occurs in Daxia, the gas supply in the building will be automatically cut off to prevent gas explosions. ④Equipment in the gas supply pipeline network of cities or factories
Gas emergency shut-off valve can be controlled centrally in the central control room, and remotely control the emergency shutdown of the pipeline gas supply at the accident site
Product details
German Leike
brand,
imported gas solenoid valveProduct Features
Solenoid valve coil power consumption
, the temperature does not exceed
℃, and the coil can be energized for a long time, the valve remains open for a long time. The valve closes quickly in case of power outage or power off. After the valve coil is powered off or powered off, the valve will not open automatically and must be opened manually. Energy-saving zero-pressure start and zero leakage.

Working principle
When the solenoid valve needs to be opened, the solenoid valve coil is energized first, then unscrew the protective sleeve on the top of the valve, and force the Pull up the handle, open the solenoid valve, and then put the protective sleeve in place to protect the handle. When the solenoid valve needs to be closed, the coil is instantly powered off and the solenoid valve is quickly closed.
