A-typed hard seat double shaft boltless butterfly valve manufacturers will show you: the common classification and use of butterfly valves

2021-07-27 11:44

The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that the butterfly valve is one of the commonly used valves for water, air, and dust. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the circular butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully open. The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that the butterfly valve is simple in structure, small in size, light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that 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 better Flow control characteristics.

Classification and use of butterfly valves:
1. The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that from the selection of materials, the butterfly valve can choose stainless steel, carbon steel, ductile iron, and galvanized materials. Different materials are selected mainly according to the working conditions, temperature, parameters, etc. For example, the temperature of carbon steel is about 400 degrees. If the temperature exceeds this temperature, stainless steel materials must be considered.
2. From the driving mode, it is divided into electric, pneumatic, manual and other modes. The A-typed hard seat double shaft boltless butterfly valve manufacturer tells you that the three common driving methods used in the previous engineering use are mainly based on the customer's choice and working conditions.
3. Distinguish from the appearance and shape, there are round, square, louver and other butterfly valves. The main choice depends on the equipment.
4. From the connection method, the main use is the clamp type, flange type, and welding type. Which connection method to use is selected according to the actual situation. The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that the wafer butterfly valve uses stud bolts to connect the valve between the two pipe flanges. The flanged butterfly valve has a flange on the valve and uses bolts to connect the valve. The flanges at both ends are connected to the pipe flanges.
5. From the perspective of the sealing surface, soft-seal butterfly valves and hard-seal butterfly valves. The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that soft-sealing butterfly valves mainly use fluorine-lined and rubber-lined materials to meet the sealing requirements, but there are restrictions on temperature. For high temperature requirements, hard-sealed butterfly valves can be used and sealed with metal materials. .
The manufacturer of A-typed hard seat double shaft boltless butterfly valve tells you that for the selection of butterfly valves in engineering equipment, the main focus is on materials, diameters, driving methods, etc. to determine the selection and price, and the main purpose is to meet the requirements of the working conditions.
