Product Description
Electric proportional integral control valve is a commonly used industrial automation control equipment. It drives the control valve through an electric actuator to achieve precise control of the flow, pressure, temperature and other parameters of the fluid medium in the pipeline.
1. The structure of the electric proportional integral control valve
The electric proportional integral control valve is mainly composed of a valve body, a valve core, an electric actuator and a control system.Among them, the valve body is the main body of the entire equipment, with a flow channel and seals inside, and various interfaces and accessories outside, such as the mounting seat of the electric actuator, the power supply interface, and the control signal interface.The valve core is the core component of the regulating valve. It can be moved up and down under the drive of an electric actuator, thereby changing the opening of the valve port and realizing the control of the fluid medium.The electric actuator is the power source of the regulating valve, and it can drive the spool to move according to the size and polarity of the control signal.The control system is the nerve center of the entire equipment. It can control the electric actuator according to the input control signal and monitor the operating status of the equipment in real time.
2. The working principle of the electric proportional integral control valve
The working principle of the electric proportional integral regulating valve is based on the basic principles of fluid mechanics, and the flow, pressure, temperature and other parameters of the fluid medium in the pipeline are controlled by adjusting the opening of the valve port.When the fluid medium in the pipeline passes through the regulating valve, it will be subjected to a certain resistance. The size of this resistance is related to the opening of the valve port.When the electric actuator receives the control signal, it will drive the valve core to move according to the size and polarity of the signal, thereby changing the opening of the valve port and realizing the control of the fluid medium.During the adjustment process, the control system will adjust the action of the electric actuator in real time according to the input control signal and the operating state of the equipment to ensure that the equipment can achieve the best control effect.
3. Characteristics of electric proportional integral control valve
1)High accuracy: The electric proportional integral control valve can accurately control the opening of the valve port according to the input control signal, so as to achieve precise control of the fluid medium.
2)Good stability: The control system of the electric proportional integral control valve can adjust the action of the electric actuator in real time according to the operating state of the equipment to ensure the stable operation of the equipment.
3)Fast response speed: The electric actuator of the electric proportional integral control valve has a high response speed, which can realize the control of the fluid medium in a short time.
4)Remote control: The electric proportional integral control valve can receive remote control signals through the control system to achieve remote control.
5)Easy maintenance: The structure of the electric proportional integral control valve is simple, easy to operate, and the maintenance cost is low.
4. The application range of electric proportional integral control valve
Electric proportional integral control valves are widely used in the field of industrial automation, such as petrochemical, electric power, water treatment, metallurgy, pharmaceutical and other industries.It can realize precise control of the flow rate, pressure, temperature and other parameters of the fluid medium, and improve the stability and efficiency of the production process.At the same time, with the continuous development of industrial automation technology, the application range of electric proportional integral control valves will also continue to expand.
In short, the electric proportional integral control valve is a commonly used industrial automation control equipment. It has the characteristics of high accuracy, good stability, fast response speed, remote control and easy maintenance, and is widely used in various industries.In the future development, with the continuous progress of industrial automation technology and the continuous expansion of application fields, electric proportional integral control valves will continue to innovate and develop.
