Description

Technical Field

[0001] The invention relates to the technical field of gas safety equipment, and in particular to a gas riser cut-off valve control device. Background Art

[0002] With the acceleration of urbanization, gas has been widely used as a clean energy. However, gas leakage accidents occur from time to time, posing a huge threat to people's lives and property. Existing gas riser shut-off valves are mostly manually operated or have simple mechanical automatic closing mechanisms. They react slowly in the face of emergencies (such as earthquakes, fires, etc.), and cannot effectively cut off the gas source in a timely manner, posing a safety hazard. Therefore, there is an urgent need for an intelligent, fast-response gas riser shut-off valve control device. Summary of the invention

[0003] The present invention aims to provide a gas riser cut-off valve control device to solve the problem that the existing gas riser cut-off valve has a slow response speed when facing an emergency and cannot cut off the gas source in time and effectively.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: A gas riser cut-off valve control device comprises a controller, a sensor module, a communication module, a power module, a solenoid valve and an alarm unit;

[0005] The controller is used to receive data from the sensor module, analyze and determine whether to trigger a cut-off instruction, and send a corresponding control signal to the solenoid valve;

[0006] The communication module is used to exchange data with an external monitoring system or other intelligent devices;

[0007] The power module ensures stable power supply to the system and also has a battery backup function to cope with sudden power outages;

[0008] The solenoid valve acts directly on the cut-off valve to achieve fast and reliable valve switching action;

[0009] The alarm unit is used to alert on-site personnel through sound and light alarms when an abnormality is detected, and can also remotely notify relevant personnel through the network.

[0010] Furthermore, the controller is a PLC controller.

The pressure sensor is electrically connected to the controller by signal. The flow sensor is also installed in the gas pipeline. The flow sensor is used to detect the gas flow and monitor whether it exceeds the set safety threshold. The flow sensor is electrically connected to the controller by signal. The temperature sensor is installed on the gas pipeline. The temperature sensor is used to monitor the ambient temperature and the gas temperature. The temperature sensor is electrically connected to the controller by signal. The leakage detection sensor is used to detect gas leakage and issue an alarm in time. The leakage detection sensor is electrically connected to the controller by signal.

[0014] Beneficial effects of the present invention:

[0015] 1. This solution integrates pressure, flow, temperature and leakage detection sensors. The system can comprehensively monitor the status of the gas pipeline, detect potential safety hazards in time and quickly close the solenoid valve.

[0020] The following is further described in detail through specific implementation methods:

[0021] The embodiment is basically as shown in the attached Figure 1 As shown:

[0022] A gas riser shut-off valve control device, including a PLC controller, a sensor module, a communication module, a power module, a solenoid valve and an alarm unit;

[0023] The controller is used to receive data from the sensor module, analyze and determine whether to trigger the cut-off instruction, and send a corresponding control signal to the solenoid valve;

[0024] The communication module is used to exchange data with external monitoring systems or other intelligent devices;

[0025] The power module ensures stable power supply to the system and also has a battery backup function to cope with sudden power outages;

[0026] The solenoid valve acts directly on the cut-off valve to achieve fast and reliable valve switching action;

[0027] The alarm unit is used to alert on-site personnel through sound and light alarms when an abnormality is detected, and can also remotely notify relevant personnel through the network.

[0028] The sensor module includes a pressure sensor, a flow sensor, a temperature sensor, multiple seismic sensors and a leakage detection sensor. The pressure sensor is installed in the gas pipeline to detect whether there is abnormally high or low pressure in the gas pipeline. The pressure sensor is connected to the controller by electrical signals;

[0029] The flow sensor is also installed in the gas pipeline. The flow sensor is used to detect the gas flow and monitor whether it exceeds the set safety threshold. The flow sensor is connected to the controller by electrical signals;

[0030] The temperature sensor is installed on the gas pipeline. The temperature sensor is used to monitor the ambient temperature and the gas temperature. The temperature sensor is connected to the controller by electrical signals.

[0031] Multiple seismic sensors are connected to the controller by electrical signals, and the multiple seismic sensors are distributed at multiple locations in the building.

[0032] The leak detection sensor is used to detect gas leaks and issue an alarm in time. The leak detection sensor is connected to the controller by electrical signals.

[0033] The power module is connected to the controller by electrical signals. The power module includes a DC power supply, a backup battery and a solar panel. The DC power supply and the backup battery are connected to the controller in parallel, and the solar panel is connected to the backup battery by electrical signals.

[0034] The specific implementation process is as follows:

[0035] When the device is in normal operation, the pressure sensors, flow sensors, temperature sensors and leak detection sensors installed in the gas pipeline continuously collect data from the environment and the inside of the pipeline, and transmit this information to the PLC controller located in the core position in real time through electrical signals. As the "brain" of the entire system, the PLC controller not only receives data from various sensors, but also performs complex analysis and processing on these data to determine whether the current situation exceeds the preset safety threshold. For example, if the pressure sensor detects abnormally high or low pressure in the pipeline, or the flow sensor finds that the gas flow exceeds the safety range, the PLC controller will immediately evaluate the significance of these signals and decide whether to trigger the cut-off command based on the built-in logic algorithm. At the same time, the temperature sensor is responsible for monitoring changes in ambient temperature and gas temperature, while the leak detection sensor is always alert to any possible gas leakage risks. Once an abnormal situation is found, all this information will be quickly transmitted to the PLC controller for comprehensive analysis.

[0036] In order to ensure that the system can continue to operate even in emergencies such as power outages, the power module uses a DC power supply in parallel with a backup battery to provide stable power support for the PLC controller and other electrical equipment. In addition, the solar panel, as an auxiliary power source, can charge the backup battery under sunshine conditions, further enhancing the system's self-sufficiency and long-term reliability. This allows the system to rely on the backup battery to maintain basic functions even if the main power fails, ensuring that key operations such as the shut-off valve will not be affected. When the PLC controller determines that the shut-off action needs to be performed, it will send a corresponding control signal to the solenoid valve. After receiving the command, the solenoid valve responds quickly and acts directly on the shut-off valve to achieve a fast and reliable valve closing action, greatly reducing the time window for gas leakage, thereby effectively reducing the possibility of accidents. At the same time, in order to remind on-site personnel to pay attention and take necessary protective measures, the alarm unit will be activated at the same time as the abnormal situation is detected, and an obvious warning signal will be issued through the sound and light alarm. The communication module will also immediately notify the relevant information to the relevant management personnel or monitoring center remotely through the network to ensure that they can obtain accurate intelligence and make appropriate responses in the first time. The multiple seismic sensors integrated in the system are distributed in different locations of the building, forming a widely covered monitoring network. When an earthquake occurs, distributed seismic sensors can capture vibration signals in a timely manner and transmit this data to the PLC controller. Since earthquakes are often accompanied by strong ground movements, which may cause physical damage to gas pipelines, rapid response to earthquake events is essential to prevent secondary disasters. In this way, the gas riser shut-off valve control device can not only respond to conventional safety threats, but also demonstrate excellent protection capabilities in the face of extreme natural disasters.
