Product Description
Product Description
I. Basic Structure
- Valve Body
- Material: Common materials include cast iron, carbon steel (such as Q235, 20# steel), stainless steel (such as 304, 316L), etc. Different materials are suitable for different working pressures and environmental requirements. Cast iron has a lower cost and is suitable for occasions with relatively weak corrosion. Stainless steel has stronger corrosion resistance and is often used in industries with high corrosion - resistance requirements, such as chemical and food industries.
- Connection Type: Mainly wafer - type, flanged - type, and lug - type. The wafer - type is easy to install and saves space, fixed by clamping between flanges on both sides of the pipeline. The flanged - type has high connection strength and good sealing performance, suitable for high - pressure and large - diameter pipelines. The lug - type combines some advantages of the wafer - type and flanged - type, facilitating installation and fixation.
- Butterfly Disc
- Main Body Material: Usually made of metal materials that match the valve body or have better corrosion resistance, such as stainless steel, to ensure sufficient strength and corrosion resistance under the scouring of the medium.
- Lining Material: Commonly used fluoroplastics include polytetrafluoroethylene (PTFE), perfluoroethylene - propylene copolymer (FEP), melt - processible polytetrafluoroethylene (PFA), etc. These fluoroplastics endow the butterfly disc with excellent corrosion resistance and high and low - temperature resistance. For example, PTFE can be used for a long time in the temperature range of - 180ºC to + 260ºC and can resist the corrosion of almost all chemical media (except molten alkali metals and elemental fluorine).
- Valve Stem
- Material: Generally, stainless steel (such as 304, 316) or alloy materials with special treatment are selected to prevent the valve stem from being corroded by the medium during operation, ensuring the normal operation and service life of the valve.
- Sealing Structure: Packing seal or mechanical seal is adopted. For packing seal, sealing packing (such as PTFE packing, flexible graphite packing, etc.) is filled in the gap between the valve stem and the valve body, and the seal is realized by tightening the gland. Mechanical seal has better sealing performance and a longer service life, suitable for harsh working conditions such as high pressure and high corrosion.
II. Working Principle
The driving device (such as manual, electric, pneumatic, etc.) drives the valve stem to rotate, and the valve stem drives the butterfly disc to make a 90° rotational movement in the valve body. When the butterfly disc rotates parallel to the pipeline axis, the valve is in the fully open state, and the medium can pass freely. When the butterfly disc rotates perpendicular to the pipeline axis, the valve is in the fully closed state, blocking the flow of the medium, so as to realize the flow control and on - off control of the medium in the pipeline.
III. Performance Parameters
- Nominal Diameter: Generally ranging from DN40 (1.5 inches) to DN1200 (48 inches), which can meet the needs of pipelines with different diameters.
- Nominal Pressure: Commonly, there are 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, etc., suitable for pipeline systems with different pressure levels.
- Applicable Temperature: Varies according to the inner - lined fluoroplastic. For example, for PTFE, the applicable temperature range is - 180ºC - + 260ºC; for FEP, the applicable temperature range is generally - 85ºC - + 150ºC.
- Leakage Class: According to national standards and industry requirements, it can generally reach a high - level sealing class, such as Class VI (zero leakage) in ANSI B16.104 standard, ensuring almost no leakage of the medium in the closed state.
IV. Product Features
- Excellent Corrosion Resistance: It can resist the corrosion of almost all chemical media, including various strong acids (such as sulfuric acid, hydrochloric acid, nitric acid), strong alkalis (such as sodium hydroxide, potassium hydroxide), strong oxidants, etc., and is widely used in industries such as chemical, pharmaceutical, printing and dyeing, electroplating that transport corrosive media.
- Good Sealing Performance: The elasticity and flexibility of the fluoroplastic lining can effectively fill the tiny gaps in the sealing surface, ensuring the sealing effect of the valve in the closed state, reducing medium leakage, and improving the safety and stability of the system.
- Low Flow Resistance: The structure of the butterfly valve makes the flow channel relatively smooth when the fluid passes through the valve, with small resistance, reducing the energy consumption during the medium transportation process and saving energy.
- Simple Operation: Whether it is manual, electric or pneumatic driving mode, it has the characteristics of simple and fast operation. In manual operation, the opening and closing of the valve can be realized by rotating the handwheel. Electric and pneumatic driving can realize remote control and automatic control, meeting the needs of modern industrial production.
- Long Service Life: Due to the use of corrosion - resistant fluoroplastic lining and high - quality metal materials, as well as a reasonable structural design, under normal use and maintenance conditions, the fluorine - lined butterfly valve has a long service life, reducing the frequency of valve replacement and maintenance, and lowering the use cost.
V. Application Fields
- Chemical Industry: Used for transporting various corrosive chemical raw materials, intermediate products and finished products, such as various acid - base solutions, organic solvents, chemical reagents, etc.
- Pharmaceutical Industry: Meeting the strict requirements of no pollution and corrosion resistance in the pharmaceutical production process, used for transporting liquid medicines, solvents, acid - base solutions and other media.
- Food and Beverage Industry: In the production, processing and transportation of food and beverages, it can be used for transporting fruit juices, beverages, wines, dairy products and other media, ensuring product hygiene and safety, and avoiding pollution caused by the contact between the medium and metal parts.
- Sewage Treatment: Suitable for treating industrial wastewater and domestic sewage containing corrosive substances, controlling the discharge and transportation of sewage, and withstanding the corrosion of various chemical substances in the sewage.
- Other Industries: In industries such as petrochemical, metallurgy, electric power, papermaking, etc., as long as it involves the transportation and control of corrosive media, the fluorine - lined butterfly valve can play an important role.
