Electromagnetic ventilation butterfly valves are actuated by an electric actuator and are mainly used for ventilation control. Comprising an electric actuator and a butterfly valve, they are mechanically connected and suitable for regulating various gas, gas, and duct processes. These valves are widely used in industries such as metallurgy, chemical, building materials, power stations, and glass, primarily in dusty cold or hot air gas pipelines, serving as flow regulating or cutting devices for gas mediums.
Operating Principle
The working principle of the electric ventilation butterfly valve is based on its unique structural design. It controls the rotation of the butterfly plate through an electric actuator (such as an angular position electric actuator), achieving the opening, closing, and adjustment of the fluid passage. The butterfly plate is installed in the diameter direction of the pipeline, with a circular disc-shaped butterfly plate rotating around the axis, with a rotation angle between 0° and 90°. When the butterfly plate rotates to 90°, the valve is fully open; and when it rotates to 0°, it is fully closed.
Application Scenario
Electromagnetic ventilation butterfly valves are suitable for various industrial fields, including:
Power Industry: Utilized in power plants and transmission and distribution systems to control the flow of water, steam, and fuel, ensuring system safety and efficiency.
Chemical Industry: Electric butterfly valves made of corrosion-resistant materials (such as stainless steel or plastic) are widely used for flow control of various liquids and gases, particularly when dealing with corrosive liquids.
Water Treatment Industry: Used for controlling flow and pressure, ensuring water quality safety and circulation efficiency.
HVAC System: Adjusts the flow of air and cooling water to optimize indoor environment and energy-saving effects.
Structural Features
The structural features of the electric ventilation butterfly valve include:
Simple structure: Fewer parts for easy assembly and disassembly.
Small in size, light in weight: easy to carry and install.
Easy Operation: Equipped with an electric actuator for valve control, operation is simple and convenient, saving on labor costs._
Excellent sealing performance: Made from high-performance materials, the sealing surface ensures reliable sealing.
