Problems solved by technology
[0003] At present, the operating pressure of the material flow regulating valve in the blast furnace bellless top charging equipment in the prior art is relatively low (0.15-0.2Mpa)
In particular, the old bell-less top charging equipment, if used on the top charging equipment of the shaft furnace, cannot be used due to the limitation of the original top pressure and equipment structure, which limits the high-pressure operation of the shaft furnace and cannot meet the requirements. Requirements for smelting and charging process of high-pressure operation of bellless top of shaft furnace

The invention discloses a high-pressure-resistance vertical furnace charge flow control valve. The high-pressure-resistance vertical furnace charge flow control valve comprises a valve body, an access hole, a wear-resisting hopper, a first valve plate, a second valve plate, an executing mechanism and anti-falling safety devices, wherein the access hole is correspondingly formed in the side part of the valve body; the wear-resisting hopper is arranged at the inner part of the valve body; the first valve plate and the second valve plate are arranged below the wear-resisting hopper; the executing mechanism is used for controlling the valve plates to be opened, and is connected with the first valve plate and the second valve plate; and the anti-falling safety devices are respectively arranged at the lower ends of the first valve plate and the second valve plate. The high-pressure-resistance vertical furnace charge flow control valve disclosed by the invention has the characteristics of prevention of the falling off of the valve plates, compact structure, safety, reliability and the like.
Description
technical field [0001] The invention relates to a high-pressure-resistant furnace top charging device for a bellless top of a shaft furnace for direct reduction smelting, in particular to a high-pressure-resistant shaft furnace material flow control valve. Background technique [0002] In recent years, although the blast furnace top pressure and utilization coefficient have been continuously improved, and the smelting intensity has been continuously increased, the domestic newly built or renovated old blast furnaces have been unable to meet the current market demand, and foreign developed countries have begun to adopt the shaft furnace of the direct reduction method. Smelting, and requires the development in the direction of high production capacity, low energy consumption, low shutdown rate, low cost, high pressure operation, and no pollution. The high-pressure-resistant charge flow control valve for high-pressure charging equipment used in shaft furnaces smelted by direct ...
