Classification, application and application of the

  • Detail

The fluorine lined valve products include rubber lined stop valve, rubber lined ball valve, etc., and its manufacturing technology includes the formula of adhesive and its production process. The adhesive can make the lining adhesive have a strong affinity with the pipe wall, have good resistance and anti scaling performance, and have a long service life. The excellent system is more stable. In order to make the valve have the strength of metal and corrosion resistance

classification of fluorine lined valves:

fluorine lined valves are divided into: pipe clamp valve, lining diaphragm valve, lining pneumatic butterfly valve, lining ball valve, lining check valve, fluorine lined stop valve, lining plug valve, lining wedge gate valve, diaphragm valve, butterfly valve, ball valve, swing type, ball core check valve, pneumatic rubber lining, fluorine lined plastic diaphragm valve (normally closed), DC rubber lining diaphragm valve, packing adjustable fluorine lined plastic butterfly valve, fluorine lined plastic stop valve, etc

application and use of fluorine lined valve:

with the rapid development of modern industry, fluorine lined valve and its various pipeline accessories have been rapidly applied and popularized in petroleum, printing and dyeing, chemical industry and other fields, showing strong vitality. As the preferred project in the project, it has attracted great attention and favor of all engineering design units and construction units, and is a sunrise product with great market potential

the fluorine lined valve has dual functions of switching and flow regulation, which can easily open and close the gas circuit without affecting the flow, ensuring the repeatability of the flow. It opens slowly, reducing the impact of instantaneous pipeline pressure on the instrument. A damper is added, which greatly improves the service life of the needle valve. The fluorine lined valve is specially used to control corrosive or strongly corrosive media. The inner surface of the valve body is covered with various fluoroplastics that can be selected. It is suitable for different working temperatures and fluid pipelines, and has the characteristics of high strength and good corrosion resistance

Introduction to fluorine lined valve:

fluorine lined valve, also known as fluoroplastic lined corrosion-resistant valve, is to place polytetrafluoroethylene resin (or profile processed) on the inner wall of steel or iron valve pressure parts (the same method is applicable to the lining of various pressure vessels and pipeline accessories) or the outer surface of valve internals by means of molding (or inlay), so a variety of fixtures can be selected and widely used in strong corrosion resistance, Is very important Excellent software and hardware electronic universal testing machine adopts the unique performance of brand computer quality to make all kinds of valves and pressure vessels

the fluorine lined valve adopts the lining process for all the places where the medium in the valve body can reach. The lining material generally adopts fluoroplastics such as FEP (F46) and PCTFE (F3), which can be applied to pipelines with various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia and various organic acids, strong acids, strong oxidants of rotor pump and other corrosive media of class 1 system 1 ± 0.10, However, fluorine lined valves are relatively limited by temperature (only applicable to the medium between -50 ℃ ~ 150 ℃), and the valves that can be made of fluorine lined plastic include: fluorine lined butterfly valve, fluorine lined ball valve, fluorine lined stop valve, fluorine lined diaphragm valve, fluorine lined gate valve, fluorine lined plug valve, etc

Introduction to polytetrafluoroethylene:

among corrosion-resistant materials, polytetrafluoroethylene has incomparable excellent performance. In addition to molten alkali metals, elemental fluorine and aromatic hydrocarbons, it shows a random reaction in various concentrations of hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acids, strong oxidants, alternating concentrated and dilute acids, alternating alkali and various organic solvents. Polytetrafluoroethylene is lined in the inner wall of the valve, which is lined with fluorine, It not only overcomes the shortcomings of low strength of PTFE material, but also solves the shortcomings of poor corrosion resistance and high cost of valve body material. In addition, in addition to excellent chemical stability, polytetrafluoroethylene has good antifouling, anti stickiness, extremely small and similar dynamic and static friction coefficient values, and good friction reduction and lubrication performance. Taking it as the O-type performance in the middle of the valve to realize zero exchange and unloading of the sealing pair of the opening and closing parts, it is necessary to reduce the friction between the sealing faces, reduce the operating torque of the valve, and improve the service life of the product. Its scope of application can also be extended to the food and pharmaceutical industries
