Fluorine-lined ball valve and butterfly valve project current development status and technical requirements

What is the current development and technical requirements of the fluorine-lined ball valve and butterfly valve project? Here are two points for everyone:

1. Briefly describe the technical route of the declared new product. Fluoroplastics are thermoplastic materials with superior performance. Typical polytetrafluoroethylene (PTFE) materials have excellent heat resistance and cold resistance, and can be in the range of -195~200℃ for a long time. use. Its low friction and self-lubricating properties are very good, and it also has excellent electrical insulation and excellent chemical stability, and can withstand the corrosion of various strong acids, strong alkalis and strong oxidants. Because fluoroplastics have these excellent characteristics, they are especially suitable for valve materials with strong corrosion resistance, and have partially replaced expensive Hastelloy and titanium alloy materials.

2. Technical route for product development of this project; Basis of design principle 1. Analyze and study the performance of fluoroplastics to determine the basis for design pressure. The design pressure of fluorine-lined valves and lined valves is based on PN≦2.0MPa (150Lb), and the operating temperature should be determined comprehensively according to the applicable temperature of the shell material and fluoroplastics. Generally, the working temperature of carbon steel fluorine-lined valves and lining valves is -29～180℃. The nominal diameters of various fluorine-lined valves and lining valves are determined according to the production conditions of the enterprise. Second, the technical conditions of fluorine-lined valves and lined valves shall be implemented with reference to the corresponding metal valve design specifications. At the same time, relevant technical requirements must be met according to its own characteristics and requirements.
