Common scenarios of triple eccentric butterfly valves
The triple eccentric butterfly valve is widely used in industrial scenarios with strict requirements for sealing performance and adaptability to working conditions due to its core advantages such as zero leakage sealing, high pressure and high temperature resistance, low flow resistance, wear resistance and corrosion resistance. The following are the most commonly used scenarios:
1.Electric power industry
It is mainly used in the boiler systems (feed water, steam pipelines), flue gas desulfurization and denitrification systems, and circulating water systems of thermal power plants and nuclear power stations. For instance, the main steam pipes of boilers and reheated steam pipes need to withstand high temperatures (up to over 500℃) and high pressures (above 10MPa). The metal hard seal structure of the triple eccentric butterfly valve can achieve zero leakage, avoiding energy waste and safety hazards caused by steam leakage. In the desulfurization system, it can withstand the erosion of corrosive media such as limestone slurry.
2.Petrochemical industry
It is applicable to the conveying pipelines of crude oil, refined oil products, and chemical raw materials (such as acid and alkali solutions, organic solvents), as well as the inlet and outlet control of reaction vessels and towers. For instance, in the medium circuits of long-distance crude oil pipelines and refining and chemical plants, the three-offset electric flanged butterfly valve can adapt to highly corrosive and high-viscosity media. Meanwhile, it opens and closes quickly, enabling rapid cutting off or regulating of the medium flow to ensure continuous and stable production.
3.Water treatment industry
Including waterworks, sewage treatment plants and industrial wastewater treatment systems. It is used in clean water transportation, sewage lifting, reclaimed water reuse and other links, especially in sewage pipes containing suspended solids and impurities. Its streamlined valve plate has low flow resistance, is not easy to clog, and its wear resistance can withstand the erosion of particles in sewage. Its sealing performance can prevent sewage leakage and cause secondary pollution.
4.Metallurgical industry
It is applied to blast furnace gas pipelines, converter steam pipelines, cooling water circulation systems, dust removal pipelines, etc. Blast furnace gas contains dust and corrosive components, and its temperature fluctuates greatly. The hard seal and wear-resistant structure of the china triple eccentric butterfly valve can work stably for a long time. Meanwhile, its rapid shut-off function can cope with emergency conditions in metallurgical production.
5.Municipal engineering
It is mainly used in urban centralized heating pipelines (high-temperature hot water, steam) and natural gas transmission and distribution pipelines. Heating pipelines need to withstand high temperatures and pressures, and natural gas pipelines have extremely high sealing requirements (to prevent leakage and explosion risks). The industrial butterfly valves can balance sealing reliability and operational convenience, and is suitable for the long-term operation requirements of municipal pipeline networks.
