The butterfly plate of the butt welding butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle between 0° and 90°. When it rotates to 90°, the valve is fully open.
Valves with metal seals generally have a longer service life than valves with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature.
If a butterfly valve is required to be used as a flow control, the main thing is to select the correct size and type of valve. The structural principle of butterfly valve is especially suitable for making large diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical industry, and water treatment, but are also used in the cooling water system of thermal power stations.
Commonly used butterfly valves include wafer butterfly valves and flange butterfly valves. The wafer butterfly valve uses studs to connect the valve between two pipe flanges. The flange butterfly valve has a flange on the valve, and the flanges on both ends of the valve are connected to the pipe flange with bolts.
Wafer butterfly valves offer several features that make them an ideal choice for a variety of applications. First, they are designed for maximum efficiency and reliability by providing tight shut-off without the need for additional seals or packing materials.
Additionally, they feature low torque requirements while still achieving high flow rates. Furthermore, wafer butterfly valves typically come with a built-in positive sealing system, which helps ensure proper operation regardless of temperature changes or pressure fluctuations Another benefit is their easy installation due to their compact size and two-piece design which eliminates the need for welding or any other specialized equipment. Their design also makes them suitable for most media such as liquids, gases, and steam, making them an ideal solution for many industrial applications.
Wafer butterfly valves are used in a variety of piping systems to regulate the flow of liquid or gas between two points. Hey provide efficient and reliable operation by allowing for quick on/off control, as well as precise regulation when necessary. Wafer butterfly valves are relatively simple to install and operate, making them a popular choice for many applications. In this article, we'll explore the basic workings of wafer butterfly valves, different types available, installation tips and more.
These valves are typically installed in pipelines that receive frequent use and must be trusted for reliable performance. Wafer butterfly valves consist of a disc mounted on the end of a stem connected to an actuator such as a hand wheel or motor.
When the valve is opened, the disc swings away from the line, creating an unrestricted path for the flow through the middle of the valve. When closed, the disc's edges come into contact with either side of the line, blocking it off completely. This design helps to ensure tight shut-off without having to install any additional seals or packing materials. The ease of installation and simple design make wafer butterfly valves a popular choice for many applications, providing cost savings over other control valves due to their shorter installation time and low maintenance requirements.
