Fluorine-Lined valve is a kind of valve with special lining material, mainly used to control the flow and pressure of various corrosive media.The lining inside the valve,made of a special polymer like PTFE/PFA(perfluoroalkoxy),increases the valve’s resistance to factors that can cause damage. The following are the uses and usage methods of lined fluorine valves:
I.Usages
Chemical industry
In chemical production, various corrosive media such as strong acids, strong alkalis, and organic solvents are often encountered. Lined fluorine valves can effectively resist the erosion of these corrosive substances and ensure the stable operation of chemical process flow.
For example, in the production processes of pesticides, fertilizers, and pharmaceuticals, lined fluorine valves are widely used in the transportation and control of corrosive liquids and gases.
Petrochemical industry
In the field of petrochemical industry, crude oil, natural gas, and various chemical products often contain corrosive components. Lined fluorine valves can work reliably under these harsh working conditions and ensure the safety of pipeline systems.
Used for the control of corrosive media in refinery, ethylene, synthetic ammonia and other devices.
Power industry
In power production, some chemical treatment systems and wastewater treatment systems will involve corrosive media. Lined fluorine valves can be used for flow control and regulation in these systems.
For example, in the desulfurization and denitrification systems of power plants, lined fluorine valves can withstand the erosion of corrosive flue gas and chemical solutions.
Environmental protection engineering
In the field of environmental protection, projects such as sewage treatment and waste gas treatment need to use corrosion-resistant valves. Lined fluorine valves just meet this demand and can effectively control the flow of corrosive media and protect the environment.
In sewage treatment plants, waste incineration plants and other places, lined fluorine valves are widely used in various pipeline systems.
Other fields
In industries such as food, medicine, and papermaking, lined fluorine valves are also used to control the flow of corrosive media. For example, in the food processing process, some acidic or alkaline cleaning agents need to be controlled through lined fluorine valves.
II. Usage methods
Preparations before installation
Before installing a lined fluorine valve, carefully check whether the model, specification, and performance of the valve meet the requirements.
Check whether the sealing surface of the valve is intact and free from damage or corrosion.
Clean the pipeline system to ensure that there are no impurities such as debris and welding slag in the pipeline.
Installation process
When installing a lined fluorine valve, pay attention to the flow direction mark of the valve to ensure correct installation.
Adopt appropriate connection methods, such as flange connection and thread connection, to ensure firm and reliable connection.
During the installation process, avoid the valve from being impacted or twisted by external forces to prevent damage to the internal structure of the valve.
Use and maintenance
When using a lined fluorine valve, open and close the valve slowly to avoid damage to the valve caused by too fast operation.
Regularly check the sealing performance of the valve and deal with it in time if there is leakage.
Perform regular maintenance on the valve, such as cleaning and lubrication, to extend the service life of the valve.
When the lined fluorine valve is not used for a long time, the valve should be kept in the closed state and properly stored.
In conclusion, lined fluorine valves have a wide range of uses and can work reliably under various corrosive media working conditions. When using lined fluorine valves, operations should be carried out in strict accordance with the installation and usage methods to ensure the performance and service life of the valve.
