WKT's hard-sealed high-temperature butterfly valve is a butterfly valve with a metal hard seal structure, which can provide reliable sealing performance under high-temperature conditions. This butterfly valve usually adopts a double eccentric or triple eccentric structure, and its sealing form can be metal-to-metal sealing, replaceable metal sealing ring-to-metal sealing, and stainless steel plate and graphite composite plate sealing ring-to-metal sealing. The butterfly valves have gradually replaced traditional cut-off and regulating valves with their high wear resistance, high temperature resistance, and corrosion resistance.
1. Small opening torque for flexible and convenient operation, saving energy.
2. Tri-eccentric structure ensures a tighter seal as the valve closes, achieving leak-free performance.
3. Resistant to high pressure, corrosion, and wear, ensuring a long service life.
4. Utilizes an elastic stainless steel sealing ring installed on the valve body to achieve true zero leakage.
5. Adjustable sealing, maintaining leak-free performance after 100,000 life cycles.
6. Special sealing structure ensures excellent sealing performance under both high-temperature and room-temperature conditions, without stress deformation.
7. Axial positioning device solves the problem of leakage caused by wear of the axial sealing surface, allowing the transmission actuator to be installed in any direction.
8. Suitable for applications in clean pipelines in the food, pharmaceutical, chemical industries, as well as industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipelines, for opening, closing, or regulating media flow.
The hard-sealed high-temperature butterfly valve adopts a multi-layer metal hard-sealed structure (soft-hard laminated metal sheet), which combines the dual advantages of metal hard sealing and soft sealing. It exhibits excellent sealing performance under both room temperature and high-temperature conditions. Additionally, its unique tri-eccentric design ensures a tighter seal as the valve closes, providing automatic compensation for sealing. The oblique plate design allows for quick opening and closing, low flow loss, and flexible, convenient, and reliable operation.
This type of butterfly valve is widely used in industries such as metallurgy, building materials, chemicals, power stations, and papermaking, especially in applications requiring bi-directional sealing. Its design is based on the three-dimensional eccentric principle, which optimizes the spatial movement trajectory of the sealing surface, eliminating friction and interference between sealing pairs. Moreover, through carefully selected sealing materials, the butterfly valve ensures reliable sealing, corrosion resistance, high-temperature resistance, and wear resistance.
1. High wear resistance and corrosion resistance: The butterfly plate seal ring and valve seat of the hard-sealed butterfly valve are usually precision-ground with high-hardness and high-toughness ceramic materials (such as zirconium oxide ZrO2), providing bubble-level sealing, wear resistance, and erosion resistance.
2. High-temperature resistance: Suitable for high-temperature environments, can work at temperatures up to 300°C or even 800°C, the specific temperature range depends on the design and material of the butterfly valve.
3. Structural optimization: The three-eccentric design reduces the torque of the butterfly valve in operation, achieving energy saving and reduced labor intensity.
4. Long life and low maintenance: Due to the high hardness and excellent corrosion resistance of high-performance ceramics, the service life of the butterfly valve is much longer than other ordinary butterfly valves, thus saving maintenance costs for customers.
5. Bidirectional sealing performance: The butterfly valve has a bidirectional sealing function, and the installation is not restricted by the flow direction of the medium, and can be installed in any direction.
6. Easy operation: The butterfly valve has a simple structure, is small in size, is lightweight, and can be quickly opened and closed by 90° rotation, which is easy to operate.
7. Fluid control characteristics: When the butterfly valve is fully opened, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop through the butterfly valve is very small, and it has good fluid control characteristics.
8. Wide application: It is suitable for many industries such as petroleum, chemical, metallurgy, mining, electricity, energy, transportation, agriculture, water treatment, and construction, especially in occasions with stricter requirements on sealing conditions, such as gas pipelines.
9. Multiple drive modes: In addition to electric, butterfly valves also include manual, worm gear drive, pneumatic, and other drive modes.
10. Optimization of structural strength and sealing performance: By optimizing the structure and size parameters of the butterfly valve body, stress concentration is avoided, equivalent stress is reduced, and the sealing pressure is adjusted to achieve a long-term and effective sealing effect.
