Description
Technical Field
The invention relates to the field of gate valves, in particular to a dust collection gate valve for a desulfurization pipeline.
Background
The gate valve is a valve which is commonly used, a valve rod drives a valve plate to move so as to realize opening and closing, and the valve plate is connected with a valve cavity in a sealing mode through a sealing device. In the moving process of the valve plate, friction exists between the valve plate and the sealing device, and after the valve plate is used for a long time, the sealing device is easy to damage, so that the sealing reliability is poor, and dust in a valve cavity is easy to leak out of the valve body to influence the field environment.
In addition, when the gate valve is closed, the valve plate is positioned in the valve cavity, and dust can be deposited on the valve plate; when the flashboard valve is opened, dust on the valve plate is easy to move out of the valve cavity along with the valve plate, and the field environment is affected.
In view of the above problems, there is a need for a valve body that prevents dust in a valve chamber from leaking out, improves sealing reliability, and has the problems of free movement and no jamming in desulfurized fly ash.
The sealing method used in the factory at present is to add a baffle at the outlet of the valve plate, fill a sealing strip between the baffle and the outlet, and screw down the bolt on the baffle to deform the sealing strip after being extruded, so as to achieve the purpose of tight contact between the sealing strip and the inserting plate, thereby realizing the sealing of the inserting plate valve.
However, the sealing method causes the sealing strip and the inserting plate to have large friction force, the sealing strip is easy to block in the opening and closing process, the sealing strip is also very seriously worn, and the inserting plate valve can leak dust after the sealing strip is seriously worn, so that the sealing strip needs to be frequently replaced.

when the inserting plate moves to the closing position, the material carrying plate is contacted with the guide rail on the upper side, the spring device is in a release state, and the triple dust removing structure is not deformed; when the plugboard moves in a translational mode from a closed position, the triple dedusting structure drives the material carrying plate to translate in the same direction, the spring device is compressed, the generated elastic reset force drives the material carrying plate to contact with the guide rail on the lower side, and the triple dedusting structure deforms after being stressed and is in close contact with the plugboard.
In a preferred embodiment: the spring device comprises two springs and four spring seats, and the spring seats are hinged with the springs.
In a preferred embodiment: the upper and lower gaps of the guide rail are larger than the thickness of the material carrying plate by 0.5 mm.
In a preferred embodiment: the triple dust removal structure is respectively as follows from top to bottom: dust removal scraper blade, dust removal rubber, dust removal felt.
The invention has the following beneficial effects:
the three-layer dust removal device is added to the valve port of the gate valve, when the gate withdraws from the valve body, dust is removed layer by layer, most of dust removed is collected into the dust box, the automatic adjusting device is installed on the dust removal plate, the tightness of the dust removal device can be adjusted, the best dust removal effect is achieved, the abrasion of dust removal materials is effectively prevented, the problem that the old gate valve is easy to abrade and is easy to block after being used is greatly solved. Place sealing rubber packing ring etc. in dust collector's position near the export, the leakproofness of reinforcing valve also can leave over the dust separation with a small part simultaneously inside the valve body.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of an adaptive triple dedusting gate valve in accordance with the present invention;
Detailed Description
In order to better understand the technical scheme of the invention, the following detailed description is made on the embodiments provided by the invention in combination with the accompanying drawings.
Referring to fig. 1, an adaptive dust removal gate valve includes: the plate inserting device comprises an inserting plate 1, a material carrying plate 3 and a top cover plate 5; triple dust removing structures 2 which are sequentially arranged are arranged between the inserting plate 1 and the material carrying plate 3;
when the inserting plate 1 moves to the closing position, the material loading plate 3 is contacted with the guide rail 6 on the upper side, the spring device 4 is in a release state, and the triple dust removing structure 2 is not deformed; when picture peg 1 was removed by the closed position translation, triple dust removal structure 2 drove and carries flitch 3 syntropy translation, and spring assembly 4 is compressed, and the elasticity restoring force that produces drives and carries flitch 3 and the contact of the guide rail 6 of downside, and triple dust removal structure 2 receives deformation after the pressure, with picture peg 1 in close contact with.
Therefore, when the inserting plate 1 withdraws from the valve body, the triple dust removing structures 2 remove dust layer by layer, most of the removed dust is collected into the dust box, the triple dust removing structures 2 are extruded by the material carrying plate 3, the tightness of the triple dust removing structures 2 can be adjusted, the best dust removing effect is achieved, the abrasion of the triple dust removing structures 2 is effectively prevented, and the problems that an old-style inserting plate valve is easy to abrade and is easy to block after being used are greatly improved. The sealing rubber gasket and the like are arranged at the position, close to the outlet, of the dust removal device, the sealing performance of the valve is enhanced, and meanwhile, a small part of left dust can be separated inside the valve body. And after the inserting plate 1 returns to the closed position, the material loading plate 3 automatically releases the extrusion on the triple dust removing structure 2, so that the friction force between the triple dust removing structure 2 and the inserting plate 1 is reduced, and the requirement of smooth movement of the inserting plate 1 is met.
In this embodiment, the spring device 4 includes two springs and four spring seats, and the spring seats are hinged to the springs.
Triple dust removal structure 2 is from top to bottom respectively: dust removal scraper blade, dust removal rubber, dust removal felt.
Foretell self-adaptation dust removal push-pull valve utilizes the component force that spring deformation produced to reach picture peg 1 and takes out triple dust removal structure 2 and compress tightly the dust removal, and picture peg 1 inserts the effect of the 2 come-ups of triple dust removal structure, and the dust removal includes following step:
step one, rotating a hand wheel, and drawing out the plug board 1;
step two, after the inserting plate 1 is pulled out outwards, the triple dust removing structure 2 is subjected to outward friction, and the material carrying plate 3 connected with the triple dust removing structure 2 slides outwards simultaneously;
thirdly, the material carrying plate 3 slides outwards to drive the spring to compress, and as the component force in the vertical direction is increased, the material carrying plate 3 presses the triple dust removing structure 2 in the gap of the guide rail 6, so as to achieve the effect of automatically adjusting the pressing force; .
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents and modifications within the scope of the description.
