Description
Technical field
The utility model relates to metallurgical ash disposal system, refers to a kind of wear-resisting slurry valve particularly.
Background technique
Slurry valve is a transporting system valve liquid-solid in the ash disposal system of a kind of magnetic separation in the mine, little choosing, mine tailing and steel mill, power plant, the gas-solid two-phase medium.The flashboard of existing slurry valve is a monoblock solid slab, by moving up and down in valve pocket, plays the effect of opening and closing.It exists main deficiency to have: the bottom of (1) valve body is an enclosed construction, and the medium that passes through comprises a large amount of solids, so bottom accumulated slag very easily causes closing of valve not in place, effect is closed in influence.Simultaneously, contact with medium thereby the sealing surface of flashboard bottom is exposed, very easily be subjected to erosion, the working life of sealing surface is very short; (2) owing between flashboard and the main valve body sealing configuration is not set,, influence the operation of valve so the easy accumulated slag of lumen stops up; (3) between valve seat and the flashboard for close contact cooperates, be hard sealing structure between the two promptly, sealability is relatively poor.
The model utility content
The purpose of this utility model is the deficiency at above-mentioned existing slurry valve, and the wear-resisting slurry valve of a kind of good seal performance, long service life is provided.
For achieving the above object, a kind of wear-resisting slurry valve that provides of the utility model is made of valve assembly and drive unit.Wherein, valve assembly comprises valve gap, valve seat, valve rod and main valve body and two auxiliary valve bodies of constituting valve pocket and medium access way.Two auxiliary valve bodies are separately fixed at the both sides of main valve body.Be provided with flashboard in the described valve pocket, the upper end of described flashboard links to each other with an end of valve rod, and the output shaft of described drive unit links to each other with the other end of valve rod.Its specialization is: the top of described flashboard is provided with pod apertures, and the lower end of flashboard is passed the end opening of described main valve body and is tightly connected with main valve body end opening place.
Described valve seat is provided with packing ring, the belleville spring that the useful trim ring of described packing ring peripheral hardware is fixing.
Also be provided with seal ring between described valve seat and the main valve body.
The end opening place of described main valve body also is provided with the filler seat of band filler, and described filler seat is provided with the Gland that is used for fixing described filler.
Described valve gap is provided with support, and described drive unit is arranged on the support.
The surface of described valve seat is coated with wear-resisting polymer material layer.
Compare with existing slurry valve, wear-resisting slurry valve of the present utility model medium channel under opening state is straight, so accumulated slag nowhere in the valve pocket makes that the keying of valve is smooth and easy; The setting of pod apertures on the flashboard, make no matter valve is under the state of standard-sized sheet or complete shut-down, flashboard is identical with the sealing surface of main valve body all the time, not only can accumulated slag in the lumen, and valve seat, seal ring etc. are located to be protected, be difficult for because of the passing through by erosion, wearing and tearing of solid dielectric, its sealing effect and working life are improved, and then also significantly improve the working life of valve; The surface of valve seat is coated with wear-resisting polymer material layer, makes this place be soft, hard sealing structure, and its sealing and wear-resisting property all obviously strengthen; In this wear-resisting slurry valve, valve is the extended valve pocket of flashboard when opening, so valve pocket need not to hold fully flashboard, the structure of valve can be compacter, volume can be done forr a short time.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, wear-resisting slurry valve of the present utility model is made of valve assembly and drive unit 16.Wherein, valve assembly comprises main valve body 12 and two auxiliary valve bodies 9 that are fixed on main valve body 12 both sides.Main valve body 12 and auxiliary valve body 9 have constituted valve pocket and medium access way.Main valve body 12 is provided with valve gap 13, and the lumen 17 of valve is enclosed on valve gap 13 and main valve body 12 tops.Valve gap 13 is provided with support 14, and above-mentioned drive unit 16 promptly is fixed on this support 14.Be provided with flashboard 8 in the valve pocket, the upper end of flashboard 8 links to each other with the lower end of valve rod 15, and the upper end of valve rod 15 links to each other with the output shaft of drive unit 16.The top of flashboard 8 is provided with pod apertures 18, the end opening of described main valve body 12 is passed in the lower end of flashboard 8, main valve body 12 end opening places are provided with filler 2 by filler seat 3 and Gland 1, make also to be provided with pad 4 between filler seat 3 and the main valve body 12 by excellent sealing between main valve body 12 and the flashboard 8.Be provided with valve seat 7 in the main valve body 12, be arranged with packing ring 10 respectively at the upper and lower end of valve seat 7, packing ring 10 is outside equipped with belleville spring 5 and fixing by trim ring 6.Between valve seat 7 and main valve body 12, also be provided with seal ring 11.The surface of valve seat 7 is coated with the wear-resisting polymer material layer of being made by the macromolecule flexible material, only needs a less seal pressure can realize sealing fully, and anti-ly wash away, wear-resisting.
Working principle of the present utility model is as follows:
Figure 1 shows that the state of valve closing, when needing to open, start drive unit 16, moment of torsion is exported by gearbox, drives valve rod 15 and moves down, and then flashboard 8 is moved down, stretch out from main valve body 12 end openings the lower end of flashboard 8, and pod apertures 18 enters valve pocket from lumen 17 simultaneously, and the utility model is promptly opened; In the time of need closing, oppositely start drive unit 16, moment of torsion is exported by gearbox, drives on the valve rod 15 to move, and then makes on the flashboard 8 and move, and the lower end of flashboard 8 enters valve pocket, and when pod apertures 18 entered lumen 17 fully, the utility model was closed.
Behind the valve closing of the present utility model, medium can not enter lumen 17, and valve all can discharge lumen 17 when standard-sized sheet or complete shut-down; Because flashboard 8 is fitted with sealing surface everywhere all the time, thus flashboard 8 in the process of moving up and down, can the swipe both sides of flashboard 8 of each sealing surface prevent fouling on the flashboard 8; When causing lumen 17 internal pressures excessive (greater than medium channel pressure) owing to thermal expansion or other reason, because the elasticity of belleville spring 5, the pressure of this lumen 17 can have been avoided the generation of security incident by being discharged in the medium channel between valve seat 7 and the flashboard 8.
