PTFE FLANGE BUTTERFLY VALVE
The manual fluorine-lined butterfly valve is a valve used for on-off and flow control of pipeline systems. It has the characteristics of corrosion resistance, easy operation, and good sealing performance.
The butterfly plate of the manual fluorine-lined butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis. The rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open. This valve is widely used in the transportation of liquids and gases in various types of industrial pipelines, especially in the use of highly corrosive media, such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, etc.
The manual fluorine-lined butterfly valve uses a fluorine-lined plastic-lined butterfly plate with a spherical sealing surface, and is equipped with a silicone rubber gasket at the base of the valve seat to adjust the sealing performance of the valve. It is easy to operate, has strict sealing performance and a long service life, and can be used for quick cutting or adjusting flow. In addition, the valve body adopts a split type to ensure that the valve shaft does not contact the fluid medium in the cavity. It is very convenient to replace the valve shaft, and the valve does not need to be disassembled from the pipeline.
In general, manual fluorine-lined butterfly valves have been widely used in chemical, petroleum, metallurgy and other fields due to their excellent corrosion resistance and sealing performance.
Valve Body And Bonnet
They are usually made of cast iron or steel and lined with fluoroplastics, this design is mainly to provide good corrosion resistance, thereby extending the service life of the valve.
Valve stem and valve disc
The valve stem and valve disc are made of stainless steel. This choice is to ensure that the valve has sufficient strength and wear resistance to maintain stable operation in harsh working environments.
Sealing ring
The sealing ring is generally made of fluororubber, which not only has good high temperature resistance, but also has excellent sealing performance, which can effectively prevent medium leakage and ensure the sealing reliability of the valve.
The turbine is an important part of the turbine fluorine-lined butterfly valve, which is used to drive the opening, closing and adjustment of the valve.
The turbine can easily realize the rapid opening and closing of the valve and flow regulation through its transmission device. In the turbine fluorine-lined butterfly valve, the design of the turbine makes the valve operation easier, while ensuring that the valve has good sealing performance and a long service life. The transmission ratio and protection level of the turbine and other parameters also enable it to adapt to the needs of different media and working conditions.
In addition, the turbine also has a certain corrosion resistance, and can maintain stable operation in some corrosive media, further broadening the application range of the turbine fluorine-lined butterfly valve.
The basic working principle of the fluorine-lined butterfly valve is similar to that of the ordinary butterfly valve, which is to adjust the medium flow by rotating the valve plate. The difference is that the valve body and valve disc of the fluorine-lined butterfly valve are lined with a layer of fluoroplastic (such as PTFE, FEP (F46) and PCTFE (F3)). This layer of fluoroplastic has extremely high chemical stability and can effectively prevent the corrosion of corrosive media such as acid, alkali, and salt to the valve, thereby greatly extending the service life of the valve.
