Description

Plate butterfly valve is a common type of butterfly valve, which is mainly composed of valve body, butterfly plate, valve stem, sealing ring and so on. The closing part of the valve is a disc-shaped butterfly plate, which can rotate 90° around its axis, which is perpendicular to the flow direction of the fluid. When the drive handle rotates, drive the valve stem and butterfly plate to rotate together to make the valve open or close. The butterfly plate of the plate butterfly valve is disc-shaped, and the sealing seat is a P-shaped rubber ring, which ensures the sealing performance of the valve and has good corrosion resistance, but it is not suitable for pipelines with high temperature media. Some types of plate butterfly valves are made directly on the valve body, or the seat is processed after surfacing with wear-resistant and corrosion-resistant materials on the valve body. Plate butterfly valve can be used as globe valve in pipeline. According to the structure, plate butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type and lever type. According to the sealing form, the plate butterfly valve can be divided into two types: soft sealing type and hard sealing type.
