Electric adjustable ventilation butterfly valve

The working principle of the electrically adjustable ventilation butterfly valve is to drive the valve stem to rotate through an electric actuator, which in turn drives the butterfly plate to rotate inside the valve body. By changing the opening of the butterfly plate, the flow rate and direction of the airflow can be adjusted. Specifically, when the electric actuator receives a control signal, it will drive the valve stem to rotate a certain angle, causing the butterfly plate to move from fully open to fully closed or vice versa. During this process, the gap between the butterfly plate and the valve seat will change, thereby achieving precise control of the airflow rate.

Electric adjustable ventilation butterfly valveIt is an industrial valve that uses an electric actuator to control the rotation of the butterfly plate, thereby adjusting the air volume and direction. This butterfly valve is widely used in various applications that require precise control of air flow and pressure, such as chemical, metallurgical, environmental protection and other industries. Its main characteristics are simple structure, easy operation, good sealing, long service life, etc.

1、 Structural characteristics

Simple structure: adopting a simple structural design, mainly composed of valve body, butterfly plate, valve stem, and electric actuator. This design makes butterfly valves more convenient to install and maintain.

Easy to operate: Remote or local operation can be achieved through electric actuators, which can quickly open or close butterfly valves to meet the needs of different working conditions. In addition, various driving methods such as manual devices, worm gear transmission devices, and pneumatic devices can be selected according to actual needs.

Good sealing performance: Using high-quality sealing materials and advanced sealing technology, the butterfly valve can maintain good sealing performance even in harsh environments such as high temperature and high pressure.

Long lifespan: By using high-quality materials and advanced manufacturing processes, it has a longer service life and reduces the frequency of replacement and maintenance.

2、 Application Fields

Electric adjustable ventilation butterfly valves are suitable for various applications that require precise control of air flow and pressure, including but not limited to the following fields:

Metallurgical industry: used for blast furnace, converter and other equipment blower systems, as well as flue gas dust removal systems.

Environmental protection industry: used in waste gas treatment system to regulate the flow and pressure of waste gas.

Petrochemical industry: used for gas transportation and control systems in various process flows.

Electric power industry: used for regulating boiler air supply and induced draft systems.

Cement industry: used for air supply and induced draft systems at the kiln head and tail.

Glass industry: used for air supply and induced draft systems in glass melting furnaces.

The working principle of the electrically adjustable ventilation butterfly valve is to drive the valve stem to rotate through an electric actuator, which in turn drives the butterfly plate to rotate inside the valve body. By changing the opening of the butterfly plate, the flow rate and direction of the airflow can be adjusted. Specifically, when the electric actuator receives a control signal, it will drive the valve stem to rotate a certain angle, causing the butterfly plate to move from fully open to fully closed or vice versa. During this process, the gap between the butterfly plate and the valve seat will change, thereby achieving precise control of the airflow rate.

4、 Installation and maintenance

The installation and maintenance of electrically adjustable ventilation butterfly valves are relatively simple, but the following points need to be noted:

Preparation before installation: Check if the product matches the actual requirements, including model, specifications, materials, etc; Prepare installation tools and auxiliary equipment; Ensure the safety and cleanliness of the installation site.

Installation process: Install according to the instructions or professional guidance; Note that the flow direction arrow marked on the valve body is consistent with the actual flow direction of the medium; Adjust the position and angle of the electric actuator to ensure its normal operation.

Maintenance: Regularly check the operating status and lubrication of the electric actuator; Check the sealing performance of the valve body and butterfly plate, and replace them promptly if damaged; Clean the valve body and surrounding environment to prevent debris from entering and affecting the normal operation of the valve.
