Abstract
The utility model relates to a kind of mass transport valve, and specifically a kind of high consistency stock Drazin inverse valve, belongs to modulating valve technical field.The structure of this modulating valve is, the pipeline section of discharging is equipped with flange, fixed tray is fixed wtih by pull bar in the outside of flange, mounted motor on fixed tray, the output shaft of motor is the screw rod facing to flange exterior edge face, on the pull bar of borehole jack on cone chassis between flange and fixed tray, cone side, chassis, with the cone just footpath, the end of pipeline section being greater than to pipeline section internal diameter, is bored in chassis and cone with the screw engaged with screw rod.The utility model structure is simple, can prevent the blocking of slurry, reduces the friction of modulating valve and suffered pressure, greatly improves the working life of modulating valve.
Description
Technical field
The utility model relates to a kind of mass transport valve, and specifically a kind of high consistency stock Drazin inverse valve, belongs to modulating valve technical field.
Background technique
Existing flow control valve is all the unlatching size adopting valve and valve body to change valve in rotation, thus controls the size of flow.But for the slurry that concentration is high; because its mobility is poor; and containing a large amount of particles in slurry; so existing Drazin inverse valve is difficult to control flow more exactly; usually can occur to carry blocking phenomenon; modulating valve is also easy to be subject to larger friction and pressure and damages, and the working life of therefore improving high consistency stock flow control valve is one of problem anxious to be resolved in industry always.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of high consistency stock Drazin inverse valve, and it can prevent the blocking of slurry, reduces the friction of modulating valve and suffered pressure, greatly improves the working life of modulating valve.
The technological scheme that the utility model adopts is: the pipeline section of discharging is equipped with flange, fixed tray is fixed wtih by pull bar in the outside of flange, mounted motor on fixed tray, the output shaft of motor is the screw rod facing to flange exterior edge face, suit cone chassis on pull bar between flange and fixed tray, cone side, chassis with just to pipeline section and footpath, the end is greater than the cone of pipeline section internal diameter, with the screw engaged with screw rod in cone chassis and cone.
Described cone surface is provided with the air drain extended back from the vertex of a cone.
The flange that pipeline section fills is front and back two pieces, and fixed tray is also front and back two pieces and motor is fixed between the fixed tray of front and back, and the corresponding mounting hole on flange, fixed tray and cone chassis of pull bar is evenly distributed with more than 2.
The beneficial effects of the utility model are: owing to adopting the mode of cone straight line motion to change the size of slurry outlet at the pipeline section port of discharging, therefore greatly can alleviate common particle and be clipped in the phenomenon causing modulating valve to wear and tear between valve and valve body; Adopt motor in the mode of pipeline section port driver cone, the maintenance of being more convenient at ordinary times, and the blocking preventing slurry preferably of this structure, also more easily adjust the output quantity of lazy flow slurry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, each label is followed successively by: flange 1, cone 2, cone chassis 3, fixed tray 4, pull bar 5, motor 6, screw rod 7, air drain 8, pipeline section 9.
Embodiment
See Fig. 1, a flange 1 is respectively filled before and after on the pipeline section 9 of discharging, three mounting holes are uniformly distributed at the excircle of flange 1, by mounting hole, three pull bars 5 are fixed in the above, the outer external part correspondence fixing front and back two pieces fixed tray 4 of pull bar 5, drive motor 6 is fixed wtih between two fixed trays 4, the output terminal of motor 6 is screw rod 7, screw rod 7 faces the outlet of pipeline section 9, pull bar 5 between flange 1 and fixed tray 4 also overlaps and is filled with a cone chassis 3, cone chassis 3 is fixed wtih the cone 2 that footpath, the end is greater than pipeline section 9 internal diameter, the vertex of a cone of cone 2 is just to pipeline section 9 outlet end, cone chassis 3 and cone 2 are processed with screw, engaged with screw rod 7 transmission by this screw.
Make the forward and reverse rotation of motor 6 by electric controller during work, thus cone chassis 3 is moved forward and backward along pull bar 5, reach the object of the size of adjustment discharging pipeline section 9 Outlet Section.Cone 2 surface is provided with the air drain 8 extended back from the vertex of a cone, and when can prevent unexpected contract fully, pipeline pressure increases the fracture phenomena caused.
