Double eccentric butterfly valve is a valve widely used in industrial pipelines. It is characterized by fast opening and closing, good control and adjustment capabilities, and can be applied to different media and temperatures. In addition, the double eccentric butterfly valve also has the advantages of corrosion resistance, wear resistance and good sealing performance, and is widely used in petroleum, chemical industry, electric power, light industry, urban water supply, drainage and other fields.
The working principle of the double eccentric butterfly valve is to realize the control and adjustment of the fluid medium by rotating the butterfly plate. With the rotation of the butterfly plate, the flow and velocity of the medium are adjusted to the required level, thus realizing the flow control. In addition, the double eccentric butterfly valve adopts a double eccentric structure design, so that the butterfly plate can maintain perfect contact with the sealing ring when it is opened and closed, ensuring the tightness of the valve.
The advantages of double eccentric butterfly valve mainly include the following aspects:
1. Good control performance: The structural design of the double eccentric butterfly valve makes it have good control and regulation performance, which can meet the needs of different media, flow and temperature.
2. Corrosion resistance and wear resistance: The double eccentric butterfly valve is made of high strength, high corrosion resistance and high wear resistance materials, which can maintain long-term and stable performance in harsh working environments.
3. Quick opening and closing: The double eccentric butterfly valve has a simple structure and is easy to operate. It can quickly open and close the valve and improve work efficiency.
4. Good sealing: the double eccentric butterfly valve adopts a double eccentric structure design in the contact process between the sealing ring and the butterfly plate, which ensures the sealing performance of the valve.
In general, the double eccentric butterfly valve is an indispensable valve in industrial pipelines. Its excellent performance and wide application make it an important part of modern chemical production. In the future production process, we should give full play to the advantages of double eccentric butterfly valves, actively apply them in practical work, and contribute to improving production efficiency and reducing energy consumption.
