1. Introduction
The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°, and when it rotates to 90°, the valve is fully open. This valve is generally installed horizontally. Butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. And only need to rotate 90 ° can quickly open and close, simple operation, at the same time the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valve has two types of sealing: elastic seal and metal seal. Elastic seal valve, the seal can be set in the valve body or attached to the butterfly plate periphery.

2. Application
Used for gas pipeline in sulfuric acid industry: entrance and exit of pre-furnace blower, entrance and exit of relay blower, tandem and interconnecting valve of electric mist elimination, entrance and exit of S02 main blower, converter regulation, entrance and exit of preheater and so on, to regulate and cut off the volume of gas to be used.
Used in sulfur acid system in the incineration, conversion, dry suction section, is the first choice of sulfur acid device with the valve brand, by the majority of users that: good sealing performance, light operation, vice corrosion, high temperature resistance, easy to operate, flexible, safe and reliable butterfly valves, has been a large number of popularization and use.
Also widely used in: chemical, petrochemical, smelting, pharmaceutical, food and other industries in SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid, and other media on the pipeline as a regulating and intercepting device to use.
