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
The present invention relates to a kind of pipe and connect discharging valve, relate in particular to a kind of pipe that is used for alumina slurry and connect discharging valve.
Background technique
Divide the slip viscosity in cell wall bottom outlet and cyclone separator flow-off tank skin outlet port bigger in the alumina producing, can not flow through sealing surface very soon, heap scabs easily.Common discharging valve is difficult to reach the requirement of blowing and sealing again.
Summary of the invention
The object of the invention provides a kind of pipe that removes scar and connects discharging valve, and it has solved existing pipe and has connect discharging valve and can't solve the technical problem that scabs of heap easily of blowing outlet port in the alumina slurry manufacturing mechanism.
Technical solution of the present invention is:
A kind of pipe that removes scar connects discharging valve, comprises discharging valve, and said discharging valve comprises valve body 6, valve seat 4, valve rod 5, flap 1, support 7, up-down handwheel 10 and locking nut 9, and the top of said valve rod 5 is screw rod 52, and its underpart is a polished rod 51; Its special way is: said discharging valve also comprises cutting mechanism; The cutting handle 8 of the upper end portion of the screw rod 52 that said cutting mechanism comprises cutting seat 2, the cutting knife 3 that is arranged on cutting seat top, the connecting sleeve 12 and the anti-switch block 13 that are arranged on polished rod 51 upper end portions of valve rod 5 that are arranged on flap upper end, be arranged on valve rod 5; Said anti-switch block 13 is movably arranged on the connecting sleeve 12, and said connecting sleeve 12 is connected on the polished rod 51; Said support is provided with cutting mark 15, and anti-switch block aligns with cutting mark 15 when flap 1 contacts with valve seat 4; The maximum cutting diameter of said cutting knife 3 is slightly less than the internal diameter of valve seat 4.
Above-mentioned cutting knife 3 comprises two groups of blades, and said two groups of blades are symmetrical set.
Above-mentioned cutting mechanism also comprises the thin chain 16 of Drop-proof, and an end of the thin chain of said Drop-proof is connected with anti-switch block, and its other end is welded on the support.
Advantage of the present invention: the present invention has designed rotary-cut mechanism in the flap upper end, through the golden blade of two combinations, can valve base inner wall and scabbing of sealing surface place be cut away, and valve sealing face is in does not all the time have the district that scabs, and valve opening and closing freely.
Description of drawings
Fig. 1 connects the structural representation of discharging valve for pipe of the present invention;
Wherein: 1-flap, 2-cut seat, 3-cutting knife, 4-valve seat, 5-valve rod, 51-polished rod; The 52-screw rod, the 6-valve body, the 7-support, 8-cuts handle, 9-locking nut, 10-up-down handwheel; The 11-key, the 12-connecting sleeve, 13-prevents switch block, the 14-seal arrangement, 15-cuts mark, the thin chain of 16-Drop-proof.
Embodiment
The pipe that the present invention can remove scar connects discharging valve, comprises discharging valve and cutting mechanism, and discharging valve comprises valve body 6, valve seat 4, valve rod 5, flap 1, support 7, up-down handwheel 10 and locking nut 9, and the top of valve rod 5 is screw rod 52, and its underpart is a polished rod 51; The cutting handle 8 of the upper end portion of the screw rod 52 that cutting mechanism comprises cutting seat 2, the cutting knife 3 that is arranged on cutting seat top, the thin chain 16 of connecting sleeve 12, Drop-proof and the anti-switch block 13 that are arranged on polished rod 51 upper end portions of valve rod 5 that are arranged on flap upper end, be arranged on valve rod 5; Anti-switch block 13 is movably arranged on the connecting sleeve 12, and connecting sleeve 12 is connected on the polished rod 51; Support is provided with cutting mark 15, and anti-switch block aligns with cutting mark 15 when flap 1 contacts with valve seat 4; The maximum cutting diameter of cutting knife 3 is slightly less than the internal diameter of valve seat 4.Cutting knife 3 comprises two groups of blades, and two groups of blades are symmetrical set.One end of the thin chain of Drop-proof is connected with anti-switch block, and its other end is welded on the support.
Working procedure: the present invention is directed to traditional pipe and connect the phenomenon that discharging valve sealing surface place is prone to scab, designed rotary-cut mechanism, two groups of blades of this mechanism design in the flap upper end.In use, rotation and lifting handwheel 10, when anti-switch block 13 arrived cutting mark 15 places of support 7, up-down handwheel 10 stopped operating; Take down anti-switch block with hand, valve rod only moves in a circle like this, tightens locking nut 9; The cutting handle 8 of up-down handwheel top is rotated back and forth 180 degree, utilize the rotation of valve rod, drive the cutting seat action that is connected on the valve rod; Through the golden blade of two combinations, can valve base inner wall and scabbing of sealing surface place be cut away, valve sealing face is in does not all the time have the district that scabs; Refill anti-switch block, periodic duty is closed up to valve fully.
Technical parameter of the present invention:
