Make A Detailed Analysis Of The Structure Of The Wafer-type Fluorine-lined Butterfly Valve, And Fully Understand It Before You Can Use It Better
Lined Butterfly Valve is a fluorine-lined butterfly valve in which the butterfly plate is installed in the diameter direction of the pipeline. In the cylindrical channel of the valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When it rotates to 90°, the valve is in a fully open state. It has a simple structure, small size, light weight, and is composed of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, which is simple to operate. At the same time, the valve has good fluid control characteristics.
When in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body. Therefore, the pressure drop generated by the clamp-type fluorine-lined butterfly valve is very small, so it has good flow control characteristics. There are two types of sealing for fluorine-lined butterfly valves: elastic sealing and metal sealing. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate.
The butterfly plate with fluorine plastic lining with a spherical sealing surface is used, and the sealing performance of the valve is adjusted with a silicone rubber gasket at the base of the valve seat. The valve is easy to operate, has a tight sealing performance, and a super long service life. It can be used to quickly cut off or adjust the flow. It is suitable for occasions that require reliable sealing and good adjustment characteristics. The valve body adopts a split type, and the seal of the current end of the valve shaft is controlled by the rotating base surface between the butterfly plate and the valve seat plus fluorine rubber, so that the product has a compact structure, beautiful appearance, reasonable process, and reliable performance. It ensures that the valve shaft does not contact the fluid medium in the cavity. It is very convenient to replace the valve shaft, and the valve does not need to be disassembled from the pipeline. The product is widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in occasions with severely corrosive media such as sulfuric acid, phosphorus, acid, strong alkali, aqua regia and other highly corrosive media.
