How does an electric ball valve work?
The core of the electric ball valve's operation lies in the coordinated operation of an electric actuator and an internal ball. When receiving an electrical signal, the actuator rotates the ball. The ball has a central through-hole. When rotated 90 degrees, the hole aligns with the pipe, allowing fluid to flow smoothly. A 90-degree reverse rotation blocks the pipe, shutting off the flow.
This design provides fast response and eliminates the need for manual operation. The sealing structure ensures leak-free closure and stable operation even in high-pressure environments. From control signal to switching operation, the entire process is efficient and precise, making it a key component in automated fluid control systems.
Application of Electric Ball Valve
Electric ball valves are primarily used for terminal waterway control in central air conditioning and heating systems. A thermostat controls the actuator to open or close the valve, allowing for the flow or disconnection of media within the pipeline. These valves, combined with fan coil units, automatically control indoor temperature. Additionally, some series of electric ball valves are widely used for fluid control in systems such as water treatment and industrial processing.
Factors to Consider in Electric Ball Valve Design
Media Characteristics: Consider the media type (liquid, gas, slurry, etc.), temperature, pressure, and corrosiveness to select the appropriate valve body and sealing materials to prevent damage from the media.
Flow Requirements: Design the ball hole size and valve body opening diameter based on the required flow range of the pipeline to ensure flow control requirements are met.
Operating Environment: Consider factors such as temperature, humidity, dust, and vibration in the installation environment to ensure stable operation of the electric actuator and valve body.
Control Accuracy: Design the electric actuator's control method and feedback mechanism based on the requirements of the automation system to ensure precise valve opening and closing angles and meet flow control accuracy requirements.
Safety: For applications involving the transport of flammable, explosive, or toxic media, explosion-proof and leak-proof structures are required to ensure operational and environmental safety.
Installation and Maintenance: Consider ease of installation and subsequent maintenance and repair during design, such as the use of removable structures.
Service Life: Improve the valve's wear and corrosion resistance and extend its service life by optimizing material selection, structural design, and processing technology.
