Deyue Valve focuses on the production, manufacturing, sales and service of hard sealing wear-resistant ball valves, electric high-performance ball valves and hydraulic eccentric hemisphere valves.
The application of double eccentric hemisphere valve is as follows: Double eccentric hemisphere valveIt is a universal valve suitable for various general industry requirements, such as water, sewage, waste water, steam, gas, paper pulp and other media.If the sealing pair is made of Cr Mn Si hard alloy and has the functions of fire resistance, explosion prevention and static electricity resistance, it is suitable for medium and high temperature media requirements, such as gas, coke oven gas, water gas, etc.If the sealing pair (hemispherical body, valve seat) and valve body passage are treated by tungsten carbide special process, it has the advantages of energy saving, good abrasion resistance, reliable sealing performance, easy operation, rapid opening and closing, long service life, etc., and is an ideal choice for valves used in industrial silicon industry pipelines. The double eccentric hemispherical valve is suitable for the harsh working conditions with particles in the medium due to its instantaneous separation and compaction characteristics between the hemispherical body and the valve seat. It can be widely used in the blast furnace pulverized coal injection, pulverizing system and various pipeline control in the dust removal system in metallurgy, mineral processing, power and other production processes.In the process of instant separation and instant compression, the hemispherical body and the valve seat can squeeze and cut to remove the scale and adhesion on the sealing surface, which can ensure tight and reliable sealing.It is the ideal choice of valves for two-phase mixed fluid medium in the process flow of transporting solution slurry, slurry ash and slag that are easy to precipitate and scale, and crystallize. At present, various specifications of double eccentric hemisphere valves have been applied to various projects in different industries, with good results and gradually expanding the scope of use.
