The generation and application of flange butterfly valve
The development of flanged butterfly valve
has a forward-looking step as China's development. China's advancement is our constant pursuit and hard work. As for the development of China, the development of butterfly valve flange can replace everything. When the modern industry is accelerating its pace of development, the flange butterfly valve comes into being. Although the flange butterfly valve is simple in structure, small in size and light in weight, it plays a vital role in the development, production and manufacture of Chinese flange butterfly valves, and has a certain impetus to the development of the Chinese valve industry. After decades of development, the current valve industry has been able to provide the departments of users with products in about twelve major categories, more than 3,000 models and more than 4,000 specifications, and its parameters of performance range from vacuum valves to 600Mpa ultra-high pressure valves. The temperature ranges from -196 degrees Celsius to 570 degrees Celsius. The medium used is water, steam, urea, ethylene, explosive and other media. It is known that at present, there are more than 2,000 valve enterprises with a certain scale on the market, most of which are distributed in Jiangsu, Zhejiang and Central Plains in China, while most valve manufacturers pay special attention to the manufacture of flange butterfly valves.
The flange butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by only rotating 90°, and the operation is simple, the valve has good fluid control characteristics at the same time. The flange butterfly plate is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°. When rotated to 90°, the valve is fully open. When in the fully open position, the thickness of the disc is the resistance that can be generated when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better characteristics in flow controlling. It is mainly used for water supply and drainage in water plants, power plants, steel mill smelting, paper making, chemical industry, food and other systems, especially for use as a regulating flow device on the water pipe.
