Abstract
The utility model discloses an anti-blockage ash discharge valve. It is provided with a conical feeding hole. The inner end of the feeding hole is provided with an elastic valve core which is connected with the rocker of the feeding hole and is hinged with the position of a valve base convex lug through a rotating shaft. The anti-blockage ash discharge valve is provided with anti-blockage of materials and big opening angle of the valve core. The anti-blockage ash discharge valve diminishes the blockage of materials and can compress and regulate sealing performance automatically through the elastic valve core.
Description
Technical field
The utility model relates to the stifled unloading valve of the anti-sticking of putting ash or discharging of flue ash bucket that a kind of smelting, chemical industry be used for the high negative pressure requirement, dust pelletizing system, material drain system.
Background technique
At present, at the unloading valve of smelting, chemical industry is used, comprise individual layer or Double-deck cinder discharge valve.Its unloading valve mainly adopts isometrical valve seat, has the material entrance of a straight-tube shape, and the inner chamber that is positioned at this material entrance has a conical surface spool by the hinged fork of rotating shaft on its fork, cooperates with straight tube end face to constitute unloading valve.Above-mentioned unloading valve, owing to be that the interior spool volume of limited height valve seat scope is big, opening angle is less relatively, promptly actual volume is little, easily causes the bulk materials card stifled, causes work intermittently.In addition, spool is that rigidity cooperates with contact seal between the material entrance, as it is little to meet the bulk materials amplitude of accommodation, and it is relatively poor sealing to occur.In addition, material entrance is a straight-tube shape, because the nonuniformity of material, when meeting bulk materials and enter, easily stops up material entrance, influences the normal discharging of unloading valve or unloads ash.
For this reason, this field need provide that a kind of adaptivity is strong, anti-sticking is stifled, and can regulate the unloading valve of sealing voluntarily.
The model utility content
The purpose of this utility model provides a kind of stifled unloading valve of anti-sticking that anti-sticking is stifled, sealability is one that collects.
For realizing this purpose, technical solution of the present utility model is finished like this.A kind of anti-sticking blocks up unloading valve, comprise valve seat, it is interior by the hinged fork of rotating shaft, the inner contact matching of one spool and material entrance is arranged on its fork, wherein, it has a taper material entrance, and there is an Elastic valve core this taper material entrance the inner, be connected with its fork, be articulated in valve seat lug position by rotating shaft.When the spool fork rotates at the lug position, strengthened the opening angle of spool and eliminated the stifled phenomenon of card.Simultaneously,, can locate automatically, improve the sealing of valve body owing to adopted elastomer body spool.
In this was novel, described Elastic valve core comprised two entity and the empty mangetic core assemblies compositions that are bowl-type, is provided with the spherical support bar at the middle part of its two assembly, is fixed on the entity component by the sphere pressing plate.
In this was novel, the entity mangetic core assembly in the described Elastic valve core was a rubber body; Described hollow spool elastic component is a spring plate body.
In this was novel, described valve seat lug one side was provided with the inclined-plane that is used to increase the fork the sphere of activities.
Anti-sticking of the present utility model blocks up unloading valve, because of the taper material entrance that adopts, prevents the stifled long-pending of material, guarantees discharging or the continuity of unloading ash; In addition, Elastic valve core has been used in design, has not only increased area of contact, can also stretch voluntarily with the pressure size of material, can strengthen the sealability of material entrance; In addition, valve seat also adopts local special-shaped lug, make its spool fork overhanging to a side, changed the gyration center of fork, like this, can effectively increase the opening angle of spool, improve the scope that material passes through, eliminated the stifled phenomenon of card, thus the working stability and the continuity that have guaranteed the material discharging or unloaded ash.
Description of drawings
Fig. 1 is this novel topology view.
Embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being further described.
By the stifled unloading valve of anti-sticking shown in Figure 1, comprise a tubular valve seat 7, an end of this valve 7 has taper material entrance 5, at the lug of the oriented outer lug of one side.One inclined-plane is arranged on this lug, by rotating shaft 9 hinged forks 8, make the fixedly connected Elastic valve core of an end of this fork 8 in it.Described Elastic valve core has two and is corresponding entity mangetic core assembly 1 and the hollow spool assemblies 4 that connect of bowl shape and combines, and hollow spool assembly 4 is fixedlyed connected with fork 8.For guarantee mangetic core assembly 1 and 4 with material entrance 5 between support cooperate intensity, and the middle part between entity mangetic core assembly 1 and hollow spool assembly 4 is provided with spherical support bar 2, is fixed on by sphere pressing plate 3 on the end face of entity mangetic core assembly 1.When fork 8 was swung the incline position of lugs by rotating shaft 9, its upper valve core also rotated thereupon like this, and this this spool is opened to maximum angle, had eliminated the stifled phenomenon of card; When spool is closed simultaneously,, realize good seal performance because the effect of fork 8 impels the spool top effectively to contact to compress voluntarily with material entrance end seal packing ring 6 and regulates.
As mentioned above, Elastic valve core entity component 1 is to adopt rubber material to make solid curved surface with bowl shape, can reduce the impact of material like this, the damage on surface and the bad connection of seal washer 6 of causing.
As mentioned above, with entity mangetic core assembly 1 another hollow spool assembly 4 that cooperates being installed is the curved surface that is bowl shape equally, and this assembly 4 is latch plates of being made by metallic material, and the compression buffer function is played in its effect equally.
In above-mentioned, it is the form that adopts non-rigidity contact that related spool contacts with material entrance.Novelly also can make following change and promptly satisfy design of the present invention it by this this structural type, as the also entity mangetic core assembly 1 of configurable taper on hollow spool assembly 4, wherein material therefor can select for use rubber or metallic material body all can.
The above-mentioned technology contents that provides; it only is the specific embodiment that provides by this novel design; after this read this novel technology contents, those skilled in the art novelly made corresponding modification or change to this, and these change and all belong to this novel scope of asking for protection.
