Description

Technical Field

[0001] This utility model relates to the field of gas solenoid valves, specifically a gas solenoid valve control device. Background Technology

[0002] A gas solenoid valve is an automated valve used in gas pipeline systems. It plays a crucial safety control role in the supply and use of gas. The solenoid coil is the core component of the gas solenoid valve. When energized, it generates a magnetic field, providing power for the valve to open or close.

[0003] Gas solenoid valves are key components for ensuring the safe supply and cut-off of gas. However, current gas solenoid valves do not have an automatic sensing and control structure. In the event of gas leaks, the gas solenoid valves cannot cut off the gas supply in time, which poses a safety hazard. Therefore, those skilled in the art have provided a gas solenoid valve control device to solve the problems mentioned in the background art. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This gas solenoid valve control device uses a pressure sensor installed on the detection cover to detect the pressure inside the connecting pipe. A gas-sensitive sensor monitors the gas concentration in the environment in real time. A microprocessor processes the electrical signals detected by the pressure sensor and the gas-sensitive sensor. When the gas concentration or pressure exceeds a preset threshold, the gas solenoid valve is automatically closed. This automatic sensing and control structure allows for timely cutting off of the gas supply in case of gas leaks, reducing safety hazards during gas use. Attached Figure Description

A pressure sensor 12 is installed inside the gas pipeline to detect the pressure inside the connecting pipe 1. When the pressure is too high or too low, a pressure abnormality signal is generated and transmitted to the microprocessor 5 for processing. The gas sensor 4 will monitor the gas concentration in the environment in real time. When the gas concentration exceeds the preset threshold, a gas leak signal is issued. The microprocessor 5 can process the gas leak signal and quickly control the gas solenoid valve 2 to close. Then, the gas solenoid valve 2 can be automatically controlled. At the same time, the buzzer 8 and the alarm flashing light 9 will be activated. The buzzer 8 and the alarm flashing light 9 can provide audible and visual alarms to the user.
