Butterfly valve is suitable for flow regulation.Because the pressure loss of butterfly valve in the pipeline is relatively large, it should also consider the solidity of butterfly plate under the pressure of pipeline medium when it is closed.In addition, consideration must be given to the operating temperature limitations of the resilient seat material at high temperatures.Butterfly valve structure length and overall height is small, open and close fast, and has good fluid control characteristics, the structure principle of butterfly valve is most suitable for the production of large diameter valve.When the butterfly valve is required to control the flow of use, the most important thing is to choose the correct size and type of butterfly valve, so that it can work properly and effectively.
Generally, short structure length and fast opening and closing speed (1/4 revolution) are required in throttling, adjusting control and mud medium.Low pressure cut-off (small pressure difference), butterfly valve is recommended.
In the two-position regulation, shrinkage mouth of the passage, low noise, cavitation and gasification phenomenon, a small amount of leakage into the atmosphere, with abrasive medium, you can choose butterfly valve.
Throttling adjustment under special working conditions, or the requirements of strict sealing, or wear serious, low temperature (cryogenic) working conditions when using butterfly valve, need to use special design of metal sealing belt adjustment device to triple eccentric or double eccentric special butterfly valve.
Butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil, acid, alkali and other pipelines with complete sealing, zero gas test leakage, high service life requirements and operating temperature of -10 ℃ ~ 150 ℃.
Eccentric butterfly valve of soft seal is suitable for bi-directional opening and closing and regulating of ventilation and dust removal pipelines. It is widely used in gas pipelines and water channels of metallurgy, light industry, electric power and petrochemical systems.
Double eccentric butterfly valve with metal to metal sealing is suitable for city heating, gas supply, water supply and other gas, oil, acid and alkali pipelines, as an adjustment and throttling device.
In addition to being used as the program control valve of large PSA gas separation device, the three-eccentric butterfly valve is widely used in petroleum, petrochemical, chemical industry, metallurgy, electric power and other fields, and is a good substitute for gate valve and globe valve.
