Product Description
I. Basic Information
- Definition: The fluorine - lined butterfly valve is a valve that uses fluorine - lining technology for wetted parts (valve body, disc, stem, etc.) based on the butterfly valve. It is a special - purpose valve for highly corrosive media. It realizes the opening, closing, and flow regulation of the valve by driving the disc to rotate around the central axis through the driving device.
- Model Example: D341F46, etc.
- Connection Types
- Wafer - type: Clamped between two pipeline flanges with stud bolts, small - sized and space - saving.
- Flanged - type: Connected to the pipeline through flanges, with stable connection and good sealing performance.
- Nominal Diameter: Commonly ranging from DN40 - DN2000, meeting the requirements of pipes with different diameters.
- Nominal Pressure: Usually 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, etc.
II. Structural Composition and Materials
- Valve Body: Usually made of cast iron, cast steel, or stainless steel, with certain strength and rigidity to withstand pipeline pressure and external mechanical stress.
- Disc: Generally made of carbon steel or stainless steel and other metal materials, with a fluoroplastic lining on the surface, such as polytetrafluoroethylene (PTFE, namely F4), perfluoroethylene - propylene (FEP, namely F46), etc., to prevent media erosion.
- Seat: Lined with fluoroplastic, cooperating with the fluoroplastic lining of the disc to form a sealing surface. Different thicknesses and hardnesses of fluoroplastic linings can be selected according to usage requirements to improve sealing performance and service life.
- Stem: Made of corrosion - resistant stainless steel or alloy materials to ensure that it is not eroded by the media during long - term use and maintain the normal operation of the valve.
III. Performance Characteristics
- Strong Corrosion Resistance: Fluoroplastics can resist the erosion of strong acids, strong alkalis, strong oxidants, and other chemical media, making it suitable for the transportation and control of various corrosive media and extending the service life of the valve. For example, in chemical production, it is used to transport media such as sulfuric acid and hydrochloric acid.
- Reliable Sealing: The fluoroplastic linings of the disc and seat cooperate closely, with good sealing performance, effectively preventing media leakage and meeting the requirements of high - sealing - demand working conditions.
- Low Friction Coefficient: The characteristics of fluoroplastics make the disc rotate flexibly with a small operating torque, reducing the load on the driving device, reducing valve wear, and improving the overall performance and reliability.
- Partially High - Temperature Resistant: Some fluoroplastics such as PTFE have good high - temperature resistance, enabling the valve to work normally in a certain high - temperature environment (for example, PTFE is suitable for temperatures from - 200ºC to 180ºC).
- Hygienic and Environment - friendly: Fluoroplastics have good chemical stability and hygienic performance, and will not contaminate the transported media, making it suitable for industries with high hygienic requirements such as food and pharmaceuticals.
IV. Driving Methods
- Manual: Operated by a handwheel or handle, with a simple structure, suitable for small - sized pipelines or occasions where remote control is not required.
- Worm - Gear Drive: Can achieve a large transmission ratio, labor - saving, and is often used for large - diameter valves.
- Pneumatic: Driven by compressed air, with rapid action, and can achieve remote control and automated operation.
- Electric: Driven by an electric motor, with high control precision, and can achieve remote control and automatic control, suitable for systems with a high degree of automation.
V. Application Scope
- Chemical Industry: Used in pipeline systems of corrosive media such as sulfuric acid, hydrochloric acid, nitric acid, and caustic soda to control the flow and on - off of the media.
- Electroplating Industry: Transport and control the flow of corrosive liquids such as electroplating solutions and pickling solutions.
- Pharmaceutical Industry: Meeting the strict requirements of pharmaceutical factories for pipeline systems, transporting and controlling corrosive pharmaceutical raw materials, solvents, and other media.
- Environmental Protection Industry: Treat sewage and wastewater containing corrosive substances such as acids and alkalis in sewage treatment plants and waste treatment plants, as well as the transportation of corrosive gases in exhaust gas treatment systems.
- Electronic Industry: Transport and control corrosive cleaning solutions, etching solutions, and other chemical reagents.
