The imported double-flanged centerline butterfly valve is a common type of butterfly valve, which is characterized by the double-flange connection of the valve body, the valve plate is round, and is located in the centerline position of the pipeline.
The valve has the following features:
The structure is simple and the operation is convenient。The structure of the double flange butterfly valve is simple, and the bolt connection between the valve seat and the valve body is adopted, which is convenient for disassembly and maintenance. The butterfly valve can be operated in a variety of ways, including manual, electric, pneumatic, etc.
Low fluid resistance and good regulation performance。The fluid resistance of the butterfly valve is small, and the rotation angle of the valve plate is only 90 degrees when the flow is adjusted, with a large adjustment range and high adjustment accuracy.
Good sealing performance。The disc of the centerline butterfly valve is located in the center line of the pipeline, which can effectively reduce the pressure difference between the seat and the disc, thereby improving the sealing performance.
The application fields of imported double-flanged centerline butterfly valve are very wide, including:
Pipeline transportation in petroleum, chemical, metallurgical and other industries。The imported double-flanged centerline butterfly valve can be used for pipeline transportation in petroleum, chemical, metallurgical and other industries, and can be used as a device to cut off and regulate the flow.
Transmission and distribution systems in the power industry。The imported double-flanged centerline butterfly valve can be used in the power transmission and distribution system of the power industry, and can be used as the cutting and regulating equipment of power pipelines.
Water supply and drainage system。The imported double flange centerline butterfly valve can be used in the water supply and drainage system, and can be used as a cut-off and regulating device.
The imported double-flange centerline butterfly valve has good performance and a wide range of application fields, and is one of the most widely used butterfly valves on the market.
The following is the specific structure of the imported double-flange centerline butterfly valve:
Valve body: The valve body is the main part of the butterfly valve, and its shape and material are determined according to different use environments. Common valve body materials are carbon steel, stainless steel, cast iron, etc.
Valve plate: The valve plate is the core component of the butterfly valve, and its shape and material are determined according to different use environments. Common disc materials are carbon steel, stainless steel, rubber, plastic, etc.
Seat: The seat is the sealing part of the butterfly valve, and its shape and material are determined according to different use environments. Common seat materials are carbon steel, stainless steel, rubber, plastic, etc.
SealsThe sealing ring is the sealing part of the butterfly valve, and its shape and material are determined according to different use environments. Common sealing ring materials are rubber, plastic, etc.
Flanges: The flange is the part that connects the butterfly valve to the pipeline, and its shape and material are determined according to different use environments. Common flange materials are carbon steel, stainless steel, etc.
The selection of imported double flange centerline butterfly valve should be carried out according to the following factors:
Fluid mediaButterfly valves are suitable for various fluid media, but for corrosive media, butterfly valves with corrosion-resistant materials should be selected.
Work pressureThe working pressure of the butterfly valve is determined according to different use environments.
Operating temperature: The working temperature of the butterfly valve is determined according to different use environments.
Flow regulation requirements: For the occasion that the flow rate needs to be accurately adjusted, the butterfly valve with good adjustment performance should be selected.
Installation:: Select the appropriate flange according to the installation method of the butterfly valve.
