Applications And Advantages of Butterfly Valves in Industrial Fluid Control

1.Basic structure and working principle of butterfly valve

Butterfly valve, also known as flap valve, is a simple regulating valve, mainly composed of valve body, valve stem, butterfly plate and sealing ring. The valve body is cylindrical, short in axial length, with a built-in butterfly plate, which rotates around the axis in the valve body. The rotation angle of the butterfly plate is usually 0°~90°. By changing the rotation angle of the butterfly plate, the flow rate and pressure of the fluid can be adjusted.

The working principle of the butterfly valve is to drive the butterfly plate to rotate around the axis in the valve body through the valve stem, thereby realizing the control of the fluid. When the butterfly plate rotates to be parallel to the pipeline axis, the valve is in the open state and the fluid can pass freely; when the butterfly plate rotates to be perpendicular to the pipeline axis, the valve is in the closed state and the fluid is cut off. By adjusting the rotation angle of the butterfly plate, the continuous adjustment of the fluid flow and pressure can be achieved.

2. Application of butterfly valves in industrial fluid control

1. Oil and gas industry

In the oil and gas industry, large butterfly valves are widely used in oil and gas transportation, distribution and measurement. Because butterfly valves have the advantages of simple structure, small size and light weight, they are particularly suitable for high-pressure and large-caliber fluid control occasions. In addition, butterfly valves also have good corrosion resistance and can operate stably for a long time under harsh working conditions.

2. Chemical industry

In the chemical industry, High-Performance butterfly valves are mainly used for the control of corrosive media such as various acid, alkali and salt solutions and organic solvents. The butterfly valve has a compact structure and good sealing performance, which can effectively prevent medium leakage and ensure production safety. At the same time, the butterfly valve has small flow resistance and low energy consumption, which is conducive to reducing production costs.

3. Power industry

In the power industry, Flow Control butterfly valves are mainly used in boiler feed water, steam transportation and condensate recovery systems. The butterfly valve has excellent high temperature resistance and can operate stably under high temperature and high pressure working conditions. In addition, the fast opening and closing function of the butterfly valve helps to improve the response speed of the system and ensure the safety and stability of power production.

4. Metallurgical industry

In the metallurgical industry, API/ANSI Compliant butterfly valves are mainly used for fluid control in production processes such as steelmaking, continuous casting, and steel rolling. The butterfly valve has good wear resistance and can withstand the impact and corrosion of high-temperature molten metal. At the same time, the rapid opening and closing function of the butterfly valve helps to improve production efficiency and reduce energy consumption.

5. Water treatment industry

In the water treatment industry, Corrosion-Resistant butterfly valves are mainly used in sewage treatment, water supply and drainage, circulating water systems and other fields. The flow channel of the butterfly valve is spacious and not easy to clog, which is conducive to the treatment of sewage containing solid particles. In addition, the butterfly valve has good sealing performance, which can effectively prevent sewage leakage and protect the environment.

3. Advantages of Full Bore butterfly valves in industrial fluid control

1. Simple structure, small size and light weight

The butterfly valve has a compact structure, small size, light weight, and is easy to install and maintain. Especially in places where space is limited, the advantages of butterfly valves are more obvious. In addition, the manufacturing cost of butterfly valves is relatively low, which is conducive to reducing the investment in engineering projects.

2. Small flow resistance and low energy consumption

The butterfly valve has a spacious flow channel and small flow resistance, which is conducive to reducing the pressure loss during fluid transportation. At the same time, the butterfly valve has a fast opening and closing speed and low energy consumption, which is conducive to reducing production costs.

3. Good sealing performance

The butterfly valve uses high-quality sealing materials such as polytetrafluoroethylene, nitrile rubber, etc., and has good sealing performance. Under normal working conditions, the butterfly valve can effectively prevent medium leakage and ensure production safety.

4. Wide range of applications

The butterfly valve is suitable for the control of various industrial fluid media, such as petroleum, chemical, electric power, metallurgy, water treatment and other industries. Especially for special working conditions such as high temperature, high pressure, strong corrosion, and containing solid particles, the butterfly valve has obvious advantages.

5. Easy maintenance

The butterfly valve has a simple structure, few parts and easy maintenance. In daily use, you only need to regularly check the wear of the seals and bearings and replace the damaged parts in time to ensure the normal operation of the valve.

Conclusion

In summary, the Resilient Seated butterfly valve has a wide range of application prospects in the field of industrial fluid control. Its simple structure, small size, light weight, small flow resistance, low energy consumption, good sealing performance, wide range of applications and easy maintenance make the butterfly valve an indispensable key equipment in the industrial fluid control system. With the continuous advancement of science and technology and the development of industry, the performance of the butterfly valve will be further improved, and its application in the field of industrial fluid control will be more extensive.
