Q1:What is butterfly valve?

A:Butterfly valve is a valve used to adjust fluid flow and pressure, its main characteristics are small size, light weight, simple structure, good sealing performance. Electric Butterfly Valves are widely used in water treatment, petrochemical, metallurgy, electric power and other fields.

Q2. What is the working principle of steel butterfly valve?

A:The working principle of butterfly valve is to control the flow of fluid by rotating the butterfly plate. When the disc is closed, fluid cannot pass through; When the disc is open, fluid can flow through the center hole of the plate. The rotation Angle of the disc is usually between 0° and 90°.

Q3. How to choose the right butterfly valve?

A:Choosing the right butterfly valve needs to consider a number of factors, such as medium type, temperature, pressure, flow, etc. For corrosive media, butterfly valves made of corrosion-resistant materials should be selected; For high temperature and high pressure occasions, high performance metal rubber seal butterfly valves should be selected. In addition, the appropriate connection and drive mode should be selected according to the actual needs.

Q4. What are the advantages and disadvantages of butterfly valves?

A:

Advantages: High performance butterfly valve has the advantages of small size, light weight, simple structure, good sealing performance and so on. At the same time, the fluid resistance of the butterfly valve is small, which can reduce energy loss.

Disadvantages: The sealing performance of the butterfly valve is affected by factors such as material aging and wear, and there may be leakage.

Q5. How to maintain the butterfly valve?

A:In order to ensure the normal operation and extend the service life of the electric actuator butterfly valve, regular maintenance should be carried out. It mainly includes cleaning the impurities on the disc and sealing ring, checking and fastening the connection parts, and regularly replacing the damaged seals. At the same time, care should be taken to prevent the butterfly valve from being subjected to excessive external impact or vibration.
