As an important component of automatic control systems, electric regulating valves are widely used in petroleum, chemical, electric power, pharmaceutical, food and other fields. Its main function is to adjust medium flow, pressure, temperature and other parameters through electric actuators to ensure the stability and accuracy of system operation. Electric regulating valves can be divided into many types according to different structures and application scenarios. This article will introduce several common electric regulating valves and their applications in industrial automation.
1. Ball valve type electric regulating valve
1). Overview
The ball valve type electric regulating valve (Electric Ball Valve) is a valve that controls the flow of the medium by rotating the ball. The ball of this type of valve has a through hole, and the rotation angle of the ball determines the opening of the through hole, thereby achieving precise control of the flow.
2). Features
Good sealing: The ball valve has good sealing performance and is particularly suitable for occasions requiring high sealing.
Easy operation: The opening and closing operation of the ball valve only requires 90 degrees, with rapid response and high control accuracy.
Wide range of applications: ball valves are suitable for a variety of media such as liquids, gases and steam, and are widely used for switch regulation of pipeline systems.
3). Application scenarios
Ball valve type electric control valves are often used in water treatment, oil and gas pipelines, chemical production lines and other fields, especially suitable for control systems that require fast response.
2. Butterfly valve type electric control valve
1). Overview
The butterfly valve type electric control valve (Electric Butterfly Valve) controls the flow of fluid by rotating the valve plate. The butterfly valve has a compact structure and is suitable for flow control of large-diameter pipelines. It is often used in occasions that require large flow regulation.
2). Features
Simple structure: The butterfly valve has a simple design, small size, light weight, and easy installation and maintenance.
Large flow capacity: The butterfly valve has a relatively thin valve plate, which can provide a large flow capacity and is suitable for handling large flow media.
Small pressure loss: The butterfly valve has a small resistance to the fluid when it is opened, which can effectively reduce pressure loss.
3). Application scenarios
Butterfly valve electric regulating valves are widely used in air conditioning systems, ventilation ducts, water treatment systems and the power industry, and are particularly suitable for low-pressure and large-diameter pipeline regulation.
3. Regulating electric gate valves
1). Overview
Regulating electric gate valves control flow by lifting or lowering the gate. This type of valve is characterized by being able to be fully opened or closed, and is often used in situations where it needs to be fully closed or opened.
2). Features
Good sealing: The gate valve has excellent sealing performance and is suitable for long-term uninterrupted working environments.
High temperature and high pressure resistance: Regulating electric gate valves are suitable for high temperature and high pressure working conditions, especially in steam and high-pressure water systems.
Strong adaptability: Can be used for most industrial media, including water, oil, steam, etc.
3). Application scenarios
Regulating electric gate valves are mainly used in power plants, petrochemical industries and other fields with high control requirements for fluids, especially for the regulation and control of high-pressure and high-temperature media.
4. Regulating Electric Globe Valve
1). Overview
Regulating Electric Globe Valve regulates the flow of fluid by lifting or pressing the valve disc, and is widely used in occasions of fine flow control. The valve body of this valve is linear, which is suitable for precise flow regulation.
2). Features
High regulation accuracy: The regulating performance of the globe valve is excellent, and it can achieve precise control of small flow.
Rapid opening and closing: The regulating electric globe valve has a fast response time and is suitable for occasions of frequent opening and closing.
Suitable for high temperature and high pressure: This type of valve is suitable for high temperature and high pressure media and can work stably under harsh working conditions.
3). Application scenarios
Regulating electric globe valves are suitable for industries such as chemical, pharmaceutical, and food processing that have high requirements for flow accuracy, especially in systems with large temperature and pressure changes.
5. Regulating Electric Control Valve
1). Overview
Regulating Electric Control Valve is a valve designed for precise control of flow, pressure or temperature. This type of valve is usually equipped with an automatic control system that can accurately adjust the flow state of the medium according to process requirements.
2). Features
High degree of automation: The regulating electric control valve can be automatically adjusted through the electric actuator and control system, saving manpower.
High precision: It can achieve precise control of process parameters such as flow, pressure, temperature, etc. to ensure the stability of the system.
Wide range of applications: It is suitable for almost all industrial media, including gas, liquid and steam.
3). Application scenarios
Regulating electric control valves are widely used in automatic control systems, such as petrochemical plants, pharmaceutical plants, boiler systems, etc., especially in processes that require high-precision control.
It can be seen that there are many types of electric control valves, and each type is designed and optimized according to different industrial needs. Ball valve type, butterfly valve type, gate valve type, stop valve type and regulating electric control valves have their own characteristics and play an important role in different application scenarios. With the development of industrial automation, the technology of electric control valves will continue to improve, helping various companies to achieve more efficient and precise process control.
