Abstract
The utility model discloses a blast furnace dry process dust remover diffuses valve, including valve gap, sealing washer, retainer plate, disk seat. The valve gap is circular lid, and its bottom surface is the plane, and with the last surfaces to mate switch of disk seat. Sealing washer and retainer plate set up in the upper surface of disk seat, and the disk seat is hugged closely to the inboard of sealing washer, and the outside of sealing washer is hugged closely to the inboard of retainer plate, and the outside of retainer plate is fixed with the marginal facies of disk seat. The utility model discloses optimize this seal structure who diffuses the valve, make its in -process opening not have sealing ring failure's trouble.
Description
Technical field
The utility model relates to mechanical skill/ironmaking/blast-furnace technique/dry-dedusting system, more particularly, relates to blast furnace dry method dust device diffusion valve.
Background technology
The diffusion valve Main Function of the fly-ash separator diffusion system of blast furnace dry method dust system is: diffuse safely this two large function when bearing sealing coal gas and abnormal pressure rising.
As shown in Figure 4, its seal form is conical surface seal to former diffusion valve sealed structure, is to realize by being with the gland 11 of tapering to be pressed in the sealing-ring 31 be in sealed base 41 groove, and the effect of pressing plate 21 is fixed in sealed base 41 by sealing-ring 31.
This diffusion valve sealed structure has a very large defect in actual use: in the process of diffusion valve opening and closing, sealing-ring 31 can deviate from sealed base 41.The reason producing this phenomenon is that, after sealing-ring 31 top hold-down 21 is completely fastening by bolt and nut, the circumferential direction of sealing-ring 31 can produce certain distortion, sealing-ring 31 is coordinated with the sealing of gland 11 and is difficult to be adjacent to.High pressure gas crush seal circle 31 produces distortion, occurs gap bottom sealing-ring 31 and between sealing groove.Make high pressure gas enter bottom sealing-ring 31, produce very large to lifting force.When thrust is greater than the pressure of sealing-ring 31 pressing plate, sealing-ring 31 is blown pressing plate.
In normal use, when the gas pressure sometimes produced in State of Blast Furnace rises, diffusion valve can carry out on-off action automatically with it, pressure release is fallen.And in process gland 11 backed down at high pressure gas, high pressure gas 51 crush seal circle 31 produces distortion, make to occur gap with sealed base 41 groove bottom sealing-ring 3.Make high pressure gas 51 enter bottom sealing-ring 31, produce very large to lifting force.When thrust is greater than the pressure of pressing plate 21, sealing-ring 31 is blown pressing plate 21.
Utility model content
Take off groove for the diffusion valve existed in prior art sealing-ring when diffusing, because seal failure causes gas leak, thus cause ironmaking energy consumption to rise, affect blast furnace ironmaking cost, the purpose of this utility model is to provide blast furnace dry method dust device diffusion valve.
For achieving the above object, the utility model adopts following technical scheme:
According to the utility model, a kind of blast furnace dry method dust device diffusion valve is provided, comprises valve gap, sealing-ring, fixed ring, valve seat.Valve gap is circular lid, and its bottom surface is plane, and coordinates switch with the upper surface of valve seat.Sealing-ring and fixed ring are arranged at the upper surface of valve seat, and valve seat is close in the inner side of sealing-ring, and the outside of sealing-ring is close in the inner side of fixed ring, and the outside of fixed ring and the edge of valve seat fix.
According to an embodiment of the present utility model, also comprise valve body, valve seat is fixedly attached to valve body.
According to an embodiment of the present utility model, also comprise bolt, nut, pad, fixed ring is connected with valve seat by bolt, and nut and pad standing bolt.
According to an embodiment of the present utility model, the contact surface of valve gap and sealing-ring adopts pile-up welding hard alloy material.
According to an embodiment of the present utility model, the top of lid is provided with lever.
According to an embodiment of the present utility model, the end of lever is provided with weight.
In technique scheme, the sealed structure of optimization nonaqueous dust cleaner diffusion valve of the present utility model, makes it in the process opened, reduce the number of stoppages of sealing-ring inefficacy.
Accompanying drawing explanation

Fig. 2 is the utility model structure vertical view;
Fig. 3 is the utility model structural section figure;
Fig. 4 is original blast furnace dry method dust device diffusion valve structure iron.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
The utility model discloses blast furnace dry method dust device diffusion valve, improve the structure of original diffusion valve inclined-plane sealing, take the structure of flat seal, it mainly comprises valve gap 1, sealing-ring 2, fixed ring 3, valve seat 4.Describe structure and the annexation of above-mentioned all parts below in detail.
General thought of the present utility model is: on valve seat 4, offer planar slot install sealing-ring 2 and valve gap 1, plane on valve seat 4 is slightly protruded in sealing-ring 2 top, valve gap 1 is made into plane, Wimet is being adopted to prevent from diffusing the erosive wear of air-flow with the face that sealing-ring 2 is combined, play again etch-proof effect, a kind of structural shape so both can seal unaffected in State of Blast Furnace during gas pressure generation fluctuation, sealing-ring 2 can be avoided again when diffusing to deviate from outside groove.
As shown in Figure 1, Figure 2 and Figure 3, valve gap 1 is circular lid, and its bottom surface is plane, and coordinates switch with the upper surface of valve seat 4.The top of valve gap 1 is provided with lever 9, and the end of lever is provided with weight 10.Valve seat 4 is irregular figure, and sealing-ring 2 and fixed ring 3 are arranged at the upper surface of valve seat 4.Sealing-ring 2 is annular, and valve seat 4 is close in its inner side, and valve gap 1 adopts pile-up welding hard alloy material with the contact surface of sealing-ring 2.Fixed ring 3 is also annular, is close to the outside of sealing-ring 2 inside it, and the outside of fixed ring 3 and the edge of valve seat fix.Fixed ring 3 is connected with valve seat 4 by bolt 5, and nut 6 and pad 7 standing bolt 5.Valve seat 4 bottom is fixedly attached to valve body 8.
The utility model makes fixing very firm of sealing-ring 2, thus avoids primary structure sealing-ring and blown the defect flown by high pressure gas.The utility model has the advantage of, valve seat 4 is offered planar slot and sealing-ring 2 is installed and compresses with fixed ring 3, sealing-ring 2 is designed to top and slightly protrudes plane on valve seat 4.Valve gap 1 is made into plane, adopts pile-up welding hard alloy to prevent the erosive wear of dispersing gas stream at the contact surface with sealing-ring 2.A kind of sealed structure pattern like this when diffusing, can be avoided high pressure gas to impact sealing-ring and making it lose efficacy.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
