Introduction and characteristics of gas emergency cut-off solenoid valve
The gas emergency cut-off solenoid valve is a new type of safety matching device for gas pipeline engineering, which is connected with the combustible gas leakage monitoring instrument. When the instrument detects the leakage of flammable gas, it automatically closes the main gas supply valve, cuts off the supply of gas, and stops the occurrence of a vicious accident in time.
Mainly used in the following occasions:
1. Connect to the flammable gas leak monitoring instrument. When the instrument detects the leakage of flammable gas, it automatically closes the main gas supply valve, cuts off the supply of gas, and stops the occurrence of a vicious accident in time.
2. Connect to the limit temperature (or pressure) safety controller of the thermal equipment. When the temperature or pressure of the detection point in the equipment exceeds the set limit value, the air supply valve is automatically closed quickly to stop the supply of fuel.
3. Connect to the central fire alarm system of the high-rise building. When a fire occurs in the building, the gas supply in the building is automatically cut off to prevent the gas explosion.
4. Set the BZCK gas emergency shut-off valve in the gas supply pipe network of the city or factory, which can be centrally controlled in the central control room, remotely remotely, and emergencyly shut down the pipeline at the accident site.
5. Reliable technical performance; extremely low load loss; extremely high safety performance; excellent energy saving performance; fast cutting performance is the five characteristics of this series of products.
Gas emergency cut-off solenoid valve features
â—†Shenzhen Euro valve is in the normally open state in daily work, the solenoid valve coil is in the power-off state, and does not consume electric energy.
â—† When an accident occurs, the valve coil is energized instantaneously, triggering the valve to close quickly and enter the self-locking state. At this time, even if it is removed
â—† When the staff handles the accident and manually reopens the valve, the air supply will be restored.
â—† The valve adopts the pilot-operated valve flap, which is easy to open. Even if the pressure reaches 6bar, it is very easy to open. The diameter is larger than DN125. The lever handle is used to make the valve reach the labor saving and fast.
Note: Normally closed emergency shut-off valve with power-off shutdown is also available upon request.

Warnings:
1.lndoor use only.
2.To avoid being damaged,do not use water or drip irrigation while using.
3.Sunshine lighting time should be 12-18 hours.
4.While irradiating the plants,the height of led grow lamp is not less than 10 inches,low height will cause the destruction of plants.
5.Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hung too high.
6.While taking care of the plants, please spray the leaves and branches 2-3 times everyday,to ensure the the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp.
