Electric Actuator Ball Valve
I. Definition and Composition
1. Definition:
• An electric actuator ball valve is a control device that uses an electric actuator to drive the rotation of the ball valve's valve core, thereby controlling the flow or cutoff of media in the pipeline.
2. Composition:
• Electric actuator: Responsible for receiving control signals and converting them into mechanical motion to drive the rotation of the ball valve's valve core.
• Ball valve: Primarily composed of a valve body, valve core (ball), valve seat, seals, etc., controlling the flow or cutoff of media through the rotation of the valve core.
II. Working Principle
1. Control Signal Reception:
• The electric actuator receives control signals from the control system (such as PLC, DCS, etc.).
2. Signal Conversion and Driving:
• The electric actuator converts the control signals into mechanical motion, driving gears, worm gears, and other transmission mechanisms through a motor to rotate the valve core.
3. Valve Core Rotation and Media Control:
• The rotation angle of the valve core determines the flow state of the media. When the valve core rotates 90 degrees, it can usually achieve complete flow or cutoff of the media.
III. Functional Characteristics
1. Automated Control:
• Electric actuator ball valves enable remote automated control, improving production efficiency.
2. High Precision:
• By precisely controlling the rotation angle of the valve core, precise adjustment of the media can be achieved.
3. High Reliability:
• Electric actuators typically have fault self-diagnosis and protection functions, ensuring stable operation of the equipment.
4. Strong Adaptability:
• Suitable for various media and operating conditions, such as high temperature, high pressure, corrosive media, etc.
IV. Application Scenarios
1. Petrochemical Industry:
• Used to control the flow of media in pipelines, ensuring smooth production processes.
2. Power Industry:
• Used for regulation and control of boiler feedwater and steam pipelines in power stations.
3. Metallurgical Industry:
• Used for regulation and control at blast furnace tuyeres, hot blast stove stacks, etc.
4. Municipal Engineering:
• Used for regulation and control of pipeline systems for tap water, sewage, natural gas, etc.
5. Other Fields:
• Such as pipeline media control in the pharmaceutical, papermaking, food processing, and other industries.
V. Precautions
1. Selection and Installation:
• Select the appropriate electric actuator ball valve based on the properties of the media, working pressure, temperature, and other conditions.
• Follow the manufacturer's installation guidelines during installation to ensure correct installation and stable operation of the equipment.
2. Maintenance and Servicing:
• Regularly maintain and service the electric actuator ball valve, including checking the wear of transmission mechanisms, seals, and other components, and replacing damaged parts.
• Clean impurities and dirt inside the valve body to ensure smooth flow of the media.
3. Safe Operation:
• Adhere to relevant safety operating procedures during operation to ensure the safety of personnel and equipment.
In summary, the "electric actuator ball valve" is an important industrial automation control component with advantages such as automated control, high precision, and high reliability. It is widely used in various industrial applications.
