The remote operation methods of electric gate valves mainly include the following:
Controlled by PLC: PLC can directly control the opening, closing, or adjustment of electric valves. The specific operation methods include:
Switch control: PLC directly controls the opening and closing of electric valves by outputting switch signals, thereby achieving fast start stop. This method has a simple structure and quick response, but it is also controllable
The accuracy is relatively low.
Analog control: PLC uses the output analog signal to adjust the opening of electric valves, thereby achieving precise control. This method has high control accuracy, but its structure
More complex and costly.
Through sensor control: PLC receives sensor signals (such as pressure, temperature, and flow sensors) to adjust the opening degree of the valve in real time, achieving precise control.
Control through human-machine interface: Operators use devices such as touch screens, keyboards, and mice to set valve parameters, while PLCs control valve actions based on input signals.
Operated through a central control system: The central control system is typically located in the control room and utilizes a human-machine interface (HMI) or monitoring and data acquisition system (SCADA) to control the electrical system
Remote monitoring and operation of dynamic gate valves.
The specific steps are as follows:
On site wiring: Install power lines, signal lines, and communication lines according to the design drawings.
Equipment installation: Install the electric gate valve, controller, communication module, and sensor in the designated location and secure them.
Communication settings: Properly configure communication protocols and parameters to ensure normal communication between devices.
System debugging: Send test instructions through the central control system to check the response of the electric gate valve and adjust parameters until they meet the requirements.
Fault detection: Implement fault detection and diagnosis to ensure the stability and reliability of the system.
Control through wired or wireless communication methods:
Wired communication methods, such as Ethernet and RS485, are suitable for use in stable environments and large-scale systems.
Wireless communication technologies, such as 4G, are highly suitable for mobile environments or places with difficult wiring.
