Description
Technical field
The utility model relates to a kind of unloading valve, especially a kind of pneumatic bell unloading valve.
Background technique
Unloading valve is the capital equipment of dusting apparatus ash discharge, air-supply and miscellaneous equipment feed, is applicable to granular material and granulated material.For industrial department extensive uses such as environmental protection, metallurgy, chemical industry, grain, food, electric power.
At present, the flashboard of bell unloading valve is opened more difficult under external influence, working efficiency is affected and structure is chaotic, complicated operation during work, therefore, just be badly in need of developing a kind of compact structure, pneumatic bell unloading valve simple to operate, through retrieval, for finding and the same or analogous device of the utility model device.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of compact structure, pneumatic bell unloading valve simple to operate.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pneumatic bell unloading valve, its innovative point is: comprise
One valve body, described valve body is bell, and the upper/lower terminal of valve body is respectively provided with an annulus convex body A along the circumferencial direction on edge on valve body, and valve body middle inside is along the circumferential direction provided with a cinder-discharging port, the bore of this cinder-discharging port reduces gradually under upper, is along the circumferential direction provided with an annulus convex body B bottom cinder-discharging port;
One cylinder, this cylinder is fixed on valve body outside by mounting plate;
One bar linkage structure, this bar linkage structure is made up of one-level connecting rod, secondary connecting rod and three grades of connecting rods, described one-level connecting rod and cylinder parallel docking, secondary connecting rod and one-level connecting rod vertical butt joint, secondary connecting rod is along the direction being parallel to valve diameter through valve body, and three grades of connecting rods are cam-shaped and vertically with secondary connecting rod fix;
One valve rod, this valve rod is connected with three grades of connecting rods of bar linkage structure, and valve rod is vertically downward;
One flashboard, this flashboard is tapered, and described flashboard is arranged on valve stem end, is along the circumferential direction provided with an annulus convex body C bottom flashboard, and this flashboard can coordinate with cinder-discharging port to be formed and seals.
Further, the upper surface of described annulus convex body C is provided with rubber seal.
The utility model has the advantage of: the utility model device passes through power by cylinder, by the effect of bar linkage structure, valve rod is driven, the conical design of cinder-discharging port can make to unload ash more smoothly, and flashboard more easily forms sealing with coordinating of cinder-discharging port simultaneously;
Rubber seal can make the sealability between cinder-discharging port and flashboard better.
