Abstract

The invention discloses a compact material flow adjusting valve, which comprises a valve body, a manhole door, a tapered sleeve and a liner barrel, wherein the manhole door is correspondingly arranged at the side part of the valve body; the tapered sleeve is supported inside the valve body; the liner barrel is supported inside the tapered sleeve; the compact material flow adjusting valve further comprises a first valve plate, a second valve plate and an executing mechanism, wherein the first valve plate and the second valve plate are correspondingly arranged below the liner barrel; the first valve plate and the second valve plate move relatively and are used for controlling the velocity or the time of material flow; and the executing mechanism are used for driving the first valve plate and the second valve plate so as to transmit power to the first valve plate and the second valve plate in a linkage way. With the adoption of the compact material flow adjusting valve, the stable and smooth operation of a blast furnace is ensured, the furnace burden segregation is prevented, the structure is compact, the height is relatively low, and the production cost is reduced effectively.

Description

technical field [0001] The invention relates to a charging device for a bellless top of an ironmaking blast furnace, in particular to a compact material flow regulating valve. Background technique [0002] In the field of metallurgical industry, the material flow regulating valve in the blast furnace bellless top charging equipment can be used to adjust the material flow speed or material flow time, so as to control and maintain the blast furnace bellless top charging equipment. The charging material in the tank tends to be uniform and reasonable in the distribution of the furnace. Adjust the opening of the valve plate of the material flow regulating valve, control the size of the material flow, and cooperate reasonably with the material distribution chute in the material distribution device to meet the requirements of various material distribution methods in the blast furnace production, thus ensuring the distribution of the furnace material in the furnace The symmetry of ...
