Abstract

The invention relates to a sluice gate valve. The sluice gate valve is mounted on a slag sluice, is used for switching off and opening a groove of the slag sluice, and comprises a gear motor, a frame, a rack, a rack base, a gear shaft, a bearing seat, a valve plate, a bottom plate and a cross beam, the gear motor drives the gear shaft to rotate through a coupling, and then the gear on the gear shaft drives the rack meshing with the gear to ascend or descend; the cross beam is fixedly installed in the groove and is opposite to the back surface of the bottom plate, a first wedge block and a second wedge block which are arranged in a matched mode are fixed to the cross beam and the back surface of the bottom plate respectively, and when the valve is closed in place, the first wedge block and the second wedge block are tightly wedged to generate force for pushing the valve plate to the bottom plate, so that the valve plate always keeps the force for pressing the sealing surface of the bottom plate, and the problem that the sealing surface of the existing slag sluice valve is easy to corrode and wear is solved.

Description

technical field [0001] The invention relates to the technical field of ironmaking blast furnace slag treatment, in particular to a slag flushing ditch gate valve. Background technique [0002] The red slag produced in the ironmaking blast furnace production process is generally quenched and cooled by slag flushing water, and then enters the water slag treatment system through the slag flushing ditch, such as sedimentation tanks, bottom filter tanks, etc. Most of the slag flushing ditch is equipped with multiple bifurcations, and each bifurcation is equipped with a valve. The slag outlet of each bifurcation corresponds to a sedimentation tank or bottom filter tank. During production, the valves of the slag flushing ditch are switched to make the Water slag selectively enters the corresponding pool. [0003] The normal operation of the slag flushing ditch valve plays an important role in ensuring the timely treatment of blast furnace slag and the orderly production of the bla...
