In industrial production environments, flanged butterfly valves are often applied and can be used to control various fluid dynamics applications, such as gases, water, steam, slurries, and oils.
How are flanged butterfly valves commonly used? First, we need to have a basic understanding of flanged butterfly valves. In terms of construction, the design of flanged butterfly valves is innovative, and due to its unique application, it has small overall specifications and is lightweight. Flanged butterfly valves use a double eccentric design, making them quick to open and close, and the actual operation is efficient.
Another important point is that there is no rolling friction between the flanged butterfly valve and the sealing ring, which helps the sealing surface resist wear. Additionally, it has a long lifespan, strong sealing, and easy adjustment. Understanding the working principles of flanged butterfly valves is also essential. The metal-sealed gate valve of the flanged butterfly valve utilizes a camshaft effect and is designed based on the triple eccentric construction principle.
On the other hand, the design of the sulfurized rubber soft-sealed disc valve adopts a single eccentric construction. The application of this principle allows for rapid detachment between the high-pressure gate valve and the sealing ring, thereby reducing friction. Next, let's discuss the characteristics of soft-sealed and hard-sealed flanged butterfly valves. Regarding soft-sealed flanged butterfly valves, they have small overall specifications, are lightweight, and have an innovative design.
They use a double eccentric design, resulting in quick opening and closing, and the actual operation is efficient. There is also no rolling friction between the butterfly plate and the sealing ring, promoting wear resistance of the sealing surface. These valves have a long lifespan, a strong seal, and are easy to adjust. As for hard-sealed flanged butterfly valves, unlike their soft-sealed counterparts, they adopt a three-dimensional eccentric construction. The high-pressure gate valve and the butterfly plate have no friction, providing a progressively tighter sealing function.
