Automatic butterfly valve, as an important part in the field of fluid control, plays a decisive role. Its high efficiency and stable performance make it widely used in various industrial pipeline systems. As the core of the automatic butterfly valve, its design and function directly determine the performance of the entire valve.
First of all, we must mention the butterfly plate, which is one of the most important parts of the automatic butterfly valve. The butterfly plate carries the critical task of opening, closing and regulating flow. Generally, the butterfly plate is made of lightweight, high-strength materials, such as stainless steel or cast steel, to ensure that it has sufficient structural strength and can still maintain stability during high-speed rotation. Its design shape is round or oval, which can minimize fluid resistance and improve the working efficiency of the valve.
In addition to the butterfly plate, the valve seat is also an indispensable key component of the automatic butterfly valve. The valve seat is located at the inlet and outlet of the valve body and closely matches the butterfly plate to form a sealing structure. It is crucial to select the appropriate valve seat material, which must have good wear resistance, corrosion resistance and sealing performance. Common valve seat materials include rubber, polytetrafluoroethylene, etc. These materials not only have excellent sealing performance, but also can adapt to various complex working environments.
In addition, the driving device is also an indispensable core component of the automatic butterfly valve. It is the power source that controls the rotation of the butterfly plate and can be electric, pneumatic or hydraulic. The electric drive device drives the reduction device through the motor to achieve precise rotation of the butterfly plate; the pneumatic and hydraulic drive devices use the pressure of gas or liquid to push the actuator to move. These drive devices feature fast response speed and high control accuracy, and can meet the precise requirements for fluid control in industrial production.
In the control system of automatic butterfly valve, the controller also plays a core role. The controller receives real-time fluid parameter signals from the sensor, and issues instructions to the drive device to adjust the rotation angle and speed of the butterfly plate according to the preset control algorithm and logic. The performance of the controller directly affects the control accuracy and response speed of the automatic butterfly valve. Therefore, it is crucial to choose a high-performance and high-reliability controller.
