What is a ventilation butterfly valve?
The ventilation butterfly valve is used in the dusty cold air or hot air pipelines of ventilation and environmental protection projects in chemical industry, building materials, power stations, glass and other industries.
The structure principle of a ventilation butterfly valve:
The structure of the ventilation butterfly valve is welded by the midline butterfly plate and the short structural steel plate, so there are no components such as connecting rods and bolts inside it, and there will be no component problems during use, so the failure rate is very low, yes A reliable valve device. And because its sealing system uses metal sealing, although the sealing effect is not as good as the elastic seal, the service life is longer than that of the elastic seal, and it has the characteristics of high temperature resistance. In the medium conveying pipeline whose temperature is not higher than 300 degrees, it can realize the function of connecting and closing regulation. This butterfly valve can also be specially customized according to the needs of customers.
Advantages of ventilation butterfly valves:
Because the gap between the butterfly plate and the valve body of the ventilation butterfly valve is large, there is enough space for expansion, so it can effectively prevent thermal expansion and contraction caused by temperature changes during use, and there will be no butterfly The board is stuck. Common butterfly valves have a variety of drive methods, including manual drive, electric drive and pneumatic drive, etc. Because of the material, this butterfly valve also has the characteristics of high temperature resistance, there will be no friction when switching, and the service life is extremely long.
Ventilation butterfly valves are designed for use in HVAC (heating, ventilation, and air conditioning) systems and other applications requiring air flow control. The applicable working conditions of ventilation butterfly valves include:
1. Temperature: The working temperature of ventilation butterfly valves typically ranges from -30°C to 120°C. The valve should be selected based on the specific temperature requirements of the application.
2. Pressure: Ventilation butterfly valves can handle low-pressure and medium-pressure applications, with a maximum working pressure of 1.6 MPa.
3. Media: Ventilation butterfly valves are designed for use with air and other gases in HVAC systems and other industrial applications.
4. Corrosion: The valve body and disc of ventilation butterfly valves are typically made from materials that are resistant to corrosion, such as ductile iron, stainless steel, or aluminum.
5. Vibration and noise: Ventilation butterfly valves are designed to minimize vibration and noise in HVAC systems.
6. Actuation: Ventilation butterfly valves can be operated manually, pneumatically, or electrically, depending on the requirements of the application.
