Abstract
The utility model relates to a kind of clog-free ore pulp valve, comprises valve body, valve seat, flashboard, valve rod, handwheel; Mainly flashboard lower semi-circle circumferential edges both sides are hypotenuse, both sides hypotenuse becomes 60 ° of angles, valve seat adopts abrasive rubber cover, this abrasive rubber cover is made up of left rubber sleeve and right rubber sleeve, the left side convex shoulder of left rubber sleeve is inlaid in the radial step of valve body left end face, the right side convex shoulder of right rubber sleeve is inlaid in the radial step of valve body its right end face, the right side of left rubber sleeve and the mutual elastic compression in left side of right rubber sleeve contact, left rubber sleeve right-hand member periphery and right rubber sleeve left end periphery are shaped with inclined-plane respectively, and inclined-plane, both sides is mutually closed forms obtuse angle structure; Valve body below left rubber sleeve and right rubber sleeve surface of contact is shaped with letdown tank.There is the features such as sealability is reliable, long service life.Be applicable to the control valve of the low pressure such as ore pulp, cement, powder, high wear medium operating mode.
Description
Technical field
The utility model belongs to valve field, particularly about a kind of plate valve.The utility model is applicable to the control valve of the low pressure such as ore pulp, cement, powder, high wear medium operating mode.
Background technique
Plate valve is the control valve of commonplace use in the ore pulp delivery ducts such as mine, coal preparation plant, cement plant, because although pulp conveying operating mode pressure is low, but there is extremely strong abrasiveness, valve seat and the ram seal face of general plate valve all adopt wear resistant alloy material, improve opposing media particle directly washing away and wear resistance sealing surface.But in flashboard opening-closing process, the particle sticking to ram seal face and sealing surface of seat surface is easy to scratch flashboard and sealing surface of seat, make metallic sealing section lose sealability very soon and occur leaking, product is low for working life.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, provides that a kind of sealability is reliable, the clog-free ore pulp valve of long service life.
The technical solution of the utility model comprises valve body, valve seat, flashboard, valve rod, handwheel, and valve rod upper end is fixedly connected with handwheel through Stem Mut, and valve rod lower end is fixedly connected with flashboard, and flashboard adopts corrosion resistant plate; Mainly flashboard lower semi-circle circumferential edges both sides are hypotenuse, both sides hypotenuse becomes 60 ° of angles, valve seat adopts abrasive rubber cover, this abrasive rubber cover is made up of left rubber sleeve and right rubber sleeve, the left side convex shoulder of left rubber sleeve is inlaid in the radial step of valve body left end face, the right side convex shoulder of right rubber sleeve is inlaid in the radial step of valve body its right end face, the right side of left rubber sleeve and the mutual elastic compression in left side of right rubber sleeve contact, left rubber sleeve right-hand member periphery and right rubber sleeve left end periphery are shaped with inclined-plane respectively, and inclined-plane, both sides is mutually closed forms obtuse angle structure; Valve body below left rubber sleeve and right rubber sleeve surface of contact is shaped with letdown tank.
In above technological scheme, in the middle part of left rubber sleeve and right rubber sleeve periphery, be shaped with toroidal cavity respectively and between valve channel inwall.
The utility model has the advantages that valve seat adopts the left rubber sleeve and right rubber sleeve closed composition mutually with elastic wear-resisting, after flashboard is opened, left rubber sleeve and right rubber sleeve close mutually, prevent medium from leaking from valve body lumen; When flashboard cuts out downwards, the surface of contact of left rubber sleeve and right rubber sleeve squeezes by the wedge angle that inclined-plane, both sides, flashboard bottom is formed, keep being sealed and matched between flashboard and both sides rubber sleeve, the medium that flashboard lower end is taken out of is discharged from valve body letdown tank, avoids media accumulation to cause flashboard jam simultaneously.There is the features such as sealability is reliable, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 valve body, 2 valve seats, 3 flashboards, 4 valve rods, 5 Stem Muts, 6 handwheels, 7 letdown tanks.
Embodiment
Clog-free ore pulp valve as shown in Figure 1, comprise valve body 1, valve seat 2, flashboard 3, valve rod 4, handwheel 6, valve rod 4 upper end is fixedly connected with handwheel 6 through Stem Mut 5, valve rod 4 and support Bracket setting anti-rotation device, by the straight line motion that the convert rotational motion of handwheel 6 is valve rod 4, valve rod 4 lower end is fixedly connected with flashboard 3, and flashboard 3 adopts corrosion resistant plate, flashboard 3 lower semi-circle circumferential edges both sides are hypotenuse, both sides hypotenuse forms 60 ° of angles, valve seat 2 adopts abrasive rubber cover, this abrasive rubber cover is made up of left rubber sleeve and right rubber sleeve, the left side convex shoulder of left rubber sleeve is inlaid in the radial step of valve body 1 left end face, the right side convex shoulder of right rubber sleeve is inlaid in the radial step of valve body 1 its right end face, the right side of left rubber sleeve and the mutual elastic compression in left side of right rubber sleeve contact, both surface of contact are on valve rod 4 axial direction, left rubber sleeve right-hand member periphery and right rubber sleeve left end periphery are shaped with inclined-plane respectively, inclined-plane, both sides is mutually closed forms obtuse angle structure, valve body 1 below left rubber sleeve and right rubber sleeve surface of contact is shaped with letdown tank 7, medium is discharged to valve body 1 from letdown tank 7, prevents medium from piling up at body cavity, affect flashboard 3 and open and close.Under flashboard 3 opening state, the right side of left rubber sleeve and the mutual elastic compression in left side of right rubber sleeve are sealed and matched, prevent medium from leaking from valve body 1 lumen, when flashboard 3 cuts out downwards, the surface of contact of left rubber sleeve and right rubber sleeve squeezes by the wedge angle that inclined-plane, both sides, flashboard 3 bottom is formed, simultaneously the left side of the right side of left rubber sleeve and right rubber sleeve respectively elasticity be close to flashboard 3 both sides sealing face, medium-tight is cut off.
Be shaped with toroidal cavity respectively and between valve body 1 vias inner walls in the middle part of left rubber sleeve and right rubber sleeve periphery, increase the resiliently deformable of left rubber sleeve and right rubber sleeve.
