Technical Advantages

I. Product introduction:

The intelligent emergency shutoff valve for natural gas is installed on the pressure fluid outgoing pipeline to prevent pipeline overpressure, pipeline leakage and other accidents, and realize the safety control of the pressure fluid pipeline. The emergency shutoff valve produced by our company, based on meeting the mechanical and electrical automatic protection functions, can be customized to add remote control, ultra-high pressure protection, and ultra-low pressure protection functions according to customer needs. 




II. Main functions: 

1.Mechanical automatic protection function: Under the condition of no external power, when the pipeline medium pressure transiently fluctuates beyond the set value, the automatic shutoff function can be realized instantly;

2.Electrical automatic protection function: In case of automatic operation, when the pipeline pressure exceeds the upper and lower limits set by the program, the device can give an alarm and conduct shutoff to realize the electrical automatic protection function;

3.Function of self-memory and self-reset after power-off: The system will memorize the execution status of the device at the moment of power failure. After being powered on again, the device will execute the uncompleted instructions at the moment of power failure or restore the status of the device at the moment of power failure;

4.Intelligent deviation correction function: When the equipment system is normal and the valve is opened (the green light is always on), press the green valve opening button for 5s to activate the intelligent deviation correction function.

5.Function of keeping valve open: The system will memorize the execution status of the device at the moment of power failure.

Additional function 1: Remote control function

The device can transmit operating parameters, faults and alarms to the remote monitoring platform in real time, and the remote monitoring platform can use the communication network to transmit instructions, so as to enable the device to achieve the remote control function;

Additional function 2: Ultra-high pressure protection function (upper limit of pressure: 4~10MPa)

Additional function 3: Ultra-low pressure protection function (lower limit of pressure: 0-2MPa)




III. Technical advantages:

1.Match the existing communication interface of the well site;

2.The smart terminal APP synchronizes the early warning and alarm information, and promptly sends a notice by SMS and phone;

3.Real-time pressure monitoring and alarm, remote operation by using a mobile APP;

4.The product has self-diagnosis, self-compensation, and self-inspection functions;  

5.Functions of self-memory and self-reset after power-off, and function of keeping valve open;

6.Historical query of daily inspection records;

7.Comprehensive cloud service support (daily equipment operation, operating data traceability, historical query, fault code and solution prompts, utilization rate, maintenance reminders, etc.)
