Abstract
The utility model relates to a valve-plugging feeding(discharging) device and belongs to a feeding and controlling device. The aims of the utility model are good airproof capability, long use life, convenient maintenance and the utility model has the ability of automatically compensating and natural abrasion. The utility model comprises a valve body, a valve base, an airproofed pressing cover, a cover board, an upper flange and a lower flange. The whole of the valve body shows a coattail shape, the top of the valve body is provided with a discharging hole, the valve body is arranged in the coattail groove which is arranged on the valve base; the cover board is arranged in a groove which is arranged on the valve base; the tops of the cover board and the valve base are all provided with feed going through holes; the tops of the upper flange and the lower flange are respectively provided with feed going through holes, and the cover board, the feed going through holes on the valve base are all corresponding to the positions of the feed going through holes on the upper flange and the lower flange. The utility model is applicable to the feeding(discharging) controls under the high airproofing conditions of solids, gases and compound materials and in particular applicable to the coaling systems or the ash discharging systems of the coal gas producers.
Description
Technical field: the utility model relates to a kind of feed control device.
Background technology: adopt the cylinder valve to come to be main frame coal feed in the existing producer gas generator, its weak point is that this cylinder valve does not have sealing function, causes gas leak serious, the influence safety in production.
Summary of the invention: the purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, provides a kind of good airproof performance, long service life, Valve-plugging easy to maintenance to supply (going out) materials device.
The utility model includes valve body, valve seat, sealing gland and sealing member, cover plate and upper and lower flange.Valve body integral body is swallow-tail form, and valve body is provided with relief hole, has on the valve seat and the corresponding dovetail-indent of valve body shape, and dovetail-indent one end sealing the other end opening is for the valve body motion; Be provided with the groove that is used to install cover plate above the dovetail-indent; Valve body is contained on the valve seat in the dovetail-indent; Cover plate is contained in the valve seat upper groove; Be equipped with material hole on cover plate, the valve seat; Also be respectively equipped with material hole on the upper and lower flange.Material hole on cover plate, the valve seat is all corresponding with upper and lower flange upper material hole position.Dovetail-indent opening one end place is provided with sealing member and sealing gland on valve seat, and sealing member adopts asbestos packing; Upper and lower flange is housed respectively on the valve seat above and below.Sealing gland is connected with upper and lower flange and valve seat respectively by screw.
When needing feed, mobile valve makes on the valve body relief hole corresponding with the material hole of upper and lower flange, cover plate and valve seat, and material passes through from material hole; When not needing feed, mobile valve makes the material hole dislocation of relief hole and upper and lower flange, cover plate and valve seat on the valve body, and material is stopped control by valve body, and material can not pass through.Valve body can be operated by cylinder or hydro-cylinder, but also manual operation.
The utility model is applicable to confession (going out) the material control under the high sealing condition of solid, liquid, gas and mixture.Be specially adapted to the coal system of producer gas generator or go out ash system.
The utility model good airproof performance, long service life, easy to maintenance, and have the ability of automatic compensation wear and tear, when the valve body motion produced wearing and tearing, valve body can move down automatically, and the wearing and tearing that valve body and valve seat junction are produced are compensated.
Description of drawings: Fig. 1 is the utility model structural representation.
Fig. 2 is the revolved sectional view along A-A line among Fig. 1.
Embodiment: valve body 1 is provided with relief hole 8, has on the valve seat 6 and the corresponding dovetail-indent of valve body 1 shape, is provided with the groove that is used to install cover plate 4 above the dovetail-indent; Valve body 1 is contained on the valve seat 6 in the dovetail-indent; Cover plate 4 is contained in valve seat 6 upper grooves; Be respectively equipped with material hole 9,11 on cover plate 4, the valve seat 6; Also be respectively equipped with material hole 10,12 on upper flange 5, the lower flange 7.Dovetail-indent opening one end place is provided with sealing member 3 and sealing gland 2 on the valve seat 6.Sealing gland 2 is connected with upper flange 5, lower flange 7, valve seat 6 respectively by screw; To seal an end be that the inclined-plane contacts with valve body 1 contact position to dovetail-indent on the valve seat 6.
