Butterfly valves are suitable for flow regulation. Because the pressure loss of the butterfly valve in the pipeline is relatively large, it is also necessary to consider the stability of the butterfly plate to accept the pipeline medium pressure when it is closed. In addition, it is necessary to consider the constraints of the operating temperature accepted by the elastic seat material at high temperatures. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has outstanding fluid control characteristics. The construction principle of the butterfly valve is most suitable for manufacturing large-diameter valves. When the butterfly valve is required to control the flow, the most important thing is to accurately select the size and type of the butterfly valve so that it can operate locally and effectively.
The center line butterfly valve usually requires short structure length and fast opening and closing speed (1/4 revolution) in saving, conditioning and controlling and mud medium. Low pressure cut-off (small pressure difference), butterfly valve is recommended.
Butterfly valve can be used when two-position conditioning, narrow passage, low noise, cavitation and vaporization appearance, a small amount of leakage to the atmosphere, and abrasive media.
Save conditioning under special working conditions, or require strict sealing, or severe wear, low temperature (cryogenic) and other working conditions when using butterfly valves, you need to use a specially designed metal seal band to adjust the equipment to triple or double Dedicated butterfly valve.
The butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil and other products that require complete sealing, zero leakage in gas experiments, high life expectancy, and operating temperature of -10 degrees to 150 degrees. Kind of acid-base and other pipelines.
The soft seal butterfly valve is suitable for the two-way opening and closing and adjustment of ventilation and dust removal pipelines, and is widely used in gas pipelines and water channels in metallurgy, light industry, electric power, and petrochemical systems.
The metal-to-metal wire sealing double migraine butterfly valve is suitable for urban heating, gas, water supply and other gas, oil, acid and alkali pipelines, as conditioning and saving equipment.
In addition to being used as a large-scale pressure swing adsorption (PSA) gas separation equipment program control valve, the metal-to-metal seal triple-partition butterfly valve can also be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields. Outstanding alternative product.
