The new safety accessories for gas pipeline projects are mainly applied as follows:
Connected to the combustible gas leakage monitoring instrument. When the instrument detects a gas leak, it will automatically and quickly close the main gas supply valve, cutting off the gas supply and promptly preventing the occurrence of a serious accident.
2. Connected to the safety controller for the maximum temperature (or pressure) of the thermal equipment. When the detected temperature or pressure within the equipment exceeds the set limit value, the gas supply valve will automatically and rapidly close, stopping the supply of fuel.
3. Connected to the central fire alarm system of the high-rise building. In case of an emergency in the building, the gas supply within the building will be automatically cut off to prevent the occurrence of a gas explosion.
4. Install ZCR gas emergency shut-off valves within the gas supply networks of cities or factories. Central control is implemented in the control room, with remote remote control capabilities. In case of an emergency, these valves can be used to shut off the gas supply to the accident site from a distance.
