Design code
Slag lock valve has the characteristics of small fluid resistance, smooth flow, quick opening and closing, easy automatic control, so it has been more and more widely used.
Floating, Trunnion, V-type full series of high performance slag lock valve, widely used in coal chemical industry, poly-silicon, petroleum, chemistry, electric power, metallurgy, cement, sugar, mining and other industries.
In addition to the structural characteristics of preventing wrong operation, preventing the valve stem from flying out, and setting the drive device installation platform, the slag lock valve also has the following technical characteristics. Lock valve sphere and valve seat completely using metal and metal sealing form, in order to ensure that the valve under various temperature and pressure reliable sealing, for different service conditions and requirements, can use a variety of advanced sphere and seat hardening technology, including supersonic spraying, nickel base alloy spray welding, special surface hardening, carbide spray welding and using high strength and high ceramic hardness, surface hardness of sphere and seat generally can reach HRC 75 above, up to HRC 90 above. The inlet and outlet adopt tungsten carbide wear-resistant alloy. Sealing surface material is not only temperature resistance, friction resistance, impact resistance and other properties. Slag lock valve can be applied to most harsh working conditions. Especially in the coal chemical industry, poly-silicon, petroleum, building materials, metallurgy, electric power, mining and other industries used more.
