Working principle and structural characteristics of DN100 electric butterfly valve

DN100  electric  butterfly valve is a widely used control valve in medium diameter pipeline systems, especially suitable for situations that require fast and reliable fluid control. Its main features are easy operation, rapid response, and good sealing performance. This article will provide a detailed introduction to the working principle and structural characteristics of the DN100 Electric Butterfly Valve.
working principle
The DN100 Electric Butterfly Valve controls the fluid inside the pipeline by driving the valve plate to rotate 90 degrees through an electric actuator. The specific work process is as follows:
1. Closed state:
-When the Electric Actuator receives a closing signal, the actuator drives the valve plate to rotate 90 degrees, making the valve plate perpendicular to the pipeline and completely blocking the flow of fluid.
-In the closed state, the valve plate is in close contact with the sealing ring, ensuring that fluid cannot pass through and achieving a good sealing effect.
2. Open status:
-When the electric actuator receives the opening signal, the actuator drives the valve plate to rotate 90 degrees in reverse, making the valve plate parallel to the pipeline and allowing fluid to pass freely.
-In the open state, the valve plate remains parallel to the pipeline, with low fluid resistance, ensuring smooth fluid flow.
3. Adjustment status:
-The DN100 electric butterfly valve can also control fluid flow by adjusting the angle of the valve plate. The actuator can adjust the position of the valve plate as needed to achieve different degrees of opening, thereby accurately controlling the fluid flow rate.
structural characteristics
1. Valve body structure:
-Valve bodies are usually made of materials such as cast iron, stainless steel, or alloy steel, which have good mechanical strength and corrosion resistance.
-The valve body design is compact and suitable for medium diameter DN100 pipelines. It is usually flange connected for easy installation and maintenance.
2. Valve plate and sealing ring:
-The valve plate is usually a circular flat plate with a shaft hole in the center, which is connected to the electric actuator through a shaft.
-The sealing ring is located at the edge of the valve plate and is commonly made of rubber, polytetrafluoroethylene (PTFE) or other high-performance sealing materials to ensure good sealing performance in the closed state.
-In order to adapt to different working conditions, the selection of sealing ring materials is particularly important to ensure reliability and durability in long-term use.
3. Electric actuator:
-The  electric actuator  is the core component of the DN100 electric butterfly valve, responsible for driving the valve plate to rotate.
-The actuator includes a motor, reducer, transmission mechanism, and control circuit, which can be operated manually, automatically, or remotely.
-Electric actuators have the characteristics of high precision, fast response, and high reliability, which can meet the control requirements under various working conditions.
4. Control system:
-DN100 electric butterfly valves are usually equipped with a control system that can receive signals from PLC, DCS, or other control systems to achieve automated control.
-The control system can monitor the status of valves and provide feedback information for easy maintenance and management.
5. Applicability:
-The DN100 electric butterfly valve is particularly suitable for industries such as water treatment, chemical, petroleum, and natural gas, and can adapt to various media and working conditions.
-Its structure is sturdy and capable of long-term stable operation in harsh environments.
Application field
The DN100 electric butterfly valve is widely used in industries such as water treatment, chemical, petroleum, natural gas, electricity, and pharmaceuticals, and is particularly suitable for situations that require medium diameter pipelines and rapid fluid control. Its compact structure and fast control performance make it an indispensable and important component of modern industrial pipeline systems.
Conclusion
The DN100 electric butterfly valve drives the valve plate to rotate through an electric actuator, achieving control and regulation of the fluid inside the pipeline. Its structure is compact and easy to operate, using high-performance sealing materials, with high precision and reliable sealing performance.
