Abstract

The invention relates to a pipe-connected discharge valve capable of removing scab. The pipe-connected discharge valve comprises a discharge valve part. The discharge valve part comprises a valve body, a valve seat, a valve rod, a valve clack, a bracket, a lifting handwheel and a locking nut, wherein a screw is arranged at the upper part of the valve rod, and a polished rod is arranged at the lower part of the valve rod; the discharge valve part further comprises a cutting mechanism; the cutting mechanism comprises a cutting seat arranged at the upper end of the valve clack, a cutting knife arranged above the cutting seat, a connecting sleeve and an anti-rotation block which are arranged at the upper end part of the polished rod of the valve rod, and a cutting handle arranged at the upper end part of the screw of the valve rod; the anti-rotation block is movably arranged on the connecting sleeve; the connecting sleeve is fixedly connected on the polished rod; a cutting mark is arranged on the bracket; the anti-rotation block aligns at the cutting mark when the valve clack is connected with the valve seat; and the maximum cutting diameter of the cutting knife is slightly smaller than the inner diameter of the valve seat. With the adoption of the pipe-connected discharge valve, the technical problem that scabs are easily accumulated at a discharge outlet of equipment for producing aluminum oxide slurry existed for the existing pipe-connected discharge valve is solved; the sealing surface of the pipe-connected discharge valve disclosed by the invention is always positioned in a non-scabbing area, and the pipe-connected discharge valve can be freely opened and closed.

Description

technical field [0001] The invention relates to a pipe connection discharge valve, in particular to a pipe connection discharge valve for alumina slurry. Background technique [0002] In alumina production, the slurry at the bottom outlet of the tank wall and the outlet of the cyclone overflow tank wall has a high viscosity, which cannot flow through the sealing surface quickly, and is easy to pile up and scar. Ordinary discharge valves are difficult to meet the requirements of discharging and sealing. Contents of the invention [0003] The object of the present invention is to provide a pipe connection discharge valve capable of removing scars, which solves the technical problem that existing pipe connection discharge valves cannot solve the problem that scars are easy to pile up at the discharge outlet of alumina slurry production equipment. [0004] Technical solution of the present invention is: [0005] A pipe connection discharge valve capable of removing scars, in...
