The use of semi-double eccentric ball valve eccentric, eccentric ball and seat, stem for rotational movement in the joint trajectory self-centering, the more closed off during tightening, completely objective to achieve a good seal. BALL VALVES The characteristics of semi-double eccentric valve: First, the sealing (valve, valve seat) - bi-metal, metal to achieve spherical ring seal, fire and explosion; Second, seal tightly, valve and valve seat seal is spherical line contact, by three-dimensional eccentric zero leakage; Third, the sealing of the valve leave compensation, use a longer time to find the valve sealing wear, just loose bolts hands-wheel side of the limit, and then turn off a little, can still achieve a reliable seal to extend service life. Fourth, the clamping sleeve can be screwed off, adjust or replace the valve seat, the valve can still be used, to avoid a large number of valve seal failure scrapped after the entire state. For welding different alloys (or combination of ball) Sealing double metals can be used for the matching wear and corrosion resistance,Globe Valves high temperature seals and demanding conditions. The usage of Semi-double eccentric valve: General valve, pipe valve, special valve slurry, gas-specific valves, petrochemical special valves, special valves six series of pulverized coal injection. In petroleum, chemical, metallurgy, electricity, gas and other industries is the gate valve, globe valve, Y-valve, ball valve replacements. Has sold the pulverized coal injection in the steel industry, aluminum industry, pulp, liquor and alumina powder transport, hydraulic power industry (or dry) ash, petrochemical industry, gas industry and other occasions.

The range of application of semi-double eccentric ball valve: 1, General valve: rational design, compact structure, with a circulation of small resistance, good sealing, easy operation and flexible,Check Valves especially suitable for water, sewage, steam, pulp and other media of low pressure pipeline network, to the preparation of electric, pneumatic devices, enabling remote automation. (Water, steam, sewage, paper pulp, slurry and other non-corrosive medium). 2, pulverized coal injection only: used to control dust and gas, fluid particles such as pulverized coal injection equipment ideal for conveying solid, widely used in metallurgy, mineral processing, power and other production processes in blast furnace pulverized coal injection, the milling system and dust control system in a variety of pipeline. It uses straight-through structure, smooth flow, will not plug fouling phenomenon, seal using Co-Cr-W alloy, specially heat-treated, anti-erosion wear resistance valve, while the eccentric spherical valve performance with automatic compensation by worm on the adjustment bolt, so that a certain degree of sealing the case of wear and tear, can achieve the effect of re-sealing. Dust and gas, particle-fluid) 3, petrochemical special: for the petrochemical industry to use high-pressure, high temperature, full of flammable, explosive, generally weak acid weak base corrosive media, with good sealing, corrosion resistance, Kai off light, which can automatically remove the valve surface fouling and material, suitable for crude oil, heavy oil and other media, transportation and oil cracking, food production and other processes.Oil, gas, gas, water, etc.).4, blast furnace gas, gas-specific: Sealing the use of Cr-Mn-Si alloy, fire proof anti-static, anti-sealing temperature 560 ℃, the ability of anti-corrosion and anti-bite are stainless steel Sealing six times, particularly suitable for gas, coke oven gas, water gas, liquefied petroleum gas, natural gas pipeline and compression station on the door to use.(Blast furnace gas, natural gas, dust and gas, etc.). Slurry mixed with special fluid: sediment transport and easy scaling, the solution crystallization slurry, ash slurry and other process fluids in the two mixed ideal process valves can break off a smooth closed barrier Filthes . Its structure and unique design, with high efficiency, good wear resistance, reliable seal, easy operation, open and close rapidly, and long lifetime.(Process slurry, ash slurry containing particulate matter such as transport) dedicated pipeline: half are straight-through valve, no necking, body channels and pipelines to connect straight pipe connected into the pipe cross-sectional area equal to the resistance is less than necking, fully open, fully closed can be achieved simply by turning 90 degrees to facilitate long-distance pipeline transport control.
