Abstract
The utility model discloses a dual-layer dual-door counter weight type air lock flap valve and relates to the field of flap devices. The valve comprises an upper single-layer dual-door counter weight flap valve and a lower single-layer dual-door counter weight flap valve, wherein the upper single-layer dual-door counter weight flap valve and the single-layer dual-door counter weight flap valve are fixed through a hexagon bolt. The valve has the characteristics of compact structure, stable and reliable work, capability of thoroughly removing dust, high sealing property, light weight, simple structure, flexible and sensitive action, and the like. The valve is widely applied to the fields of building materials, metallurgy, chemical industry, electric power and the like. As a dust hopper unloading device of various de-dusting equipment and a feeding and unloading device of equipment, such as various mills, driers and rotten material cabins, the valve can prevent wild wind from blowing.
Description
Technical field
The utility model relates to the panel turnover device field, is specifically related to a kind of double layer double door type heavy-hammer type air-locking Flap valve.
Background technique
At present, Flap valve in industries such as electric power, metallurgy, coal, chemical industry, cement as a kind of feeding device extensive use, but because the weight linear meter of the type heavy-hammer type air-locking Flap valve in the conventional construction does not have automatic reset mechanism, can not in time finish the conveying of material, thereby cause work unreliable.
Summary of the invention
The purpose of this utility model provides a kind of double layer double door type heavy-hammer type air-locking Flap valve, and its compact structure, working stability are reliable, have unload ash thoroughly, good airproof performance, lightweight, simple in structure, the characteristics such as be active in one's movements.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises up and down two two-door weight Flap valves of individual layer, and the two-door weight Flap valve of described upper individual layer is fixed by hex head bolt and the two-door weight Flap valve of lower individual layer.
Adopt the asbestos rope sealing between two two-door weight Flap valves of individual layer about described.
The utility model compact structure, working stability are reliable, have unload ash thoroughly, good airproof performance, lightweight, simple in structure, the characteristics such as be active in one's movements; Be widely used in the industries such as building materials, metallurgy, chemical industry, electric power, the discharge mechanism of giving as equipment such as the ash bucket discharge mechanism of all kinds of dusting apparatuss and various grinding machine, dryer, mashed feed bins prevents that wild wind is blown into.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
With reference to Fig. 1-Fig. 2, this embodiment by the following technical solutions: it comprises up and down two two-door weight Flap valves 1 of individual layer, and the two-door weight Flap valve 1 of described upper individual layer is fixing by the two-door weight Flap valve of hex head bolt 2 and lower individual layer 1.
Adopt the asbestos rope sealing between two two-door weight Flap valves 1 of individual layer about described.
This embodiment adopts Plate Welding to form, the weight linear meter automatic reset mechanism, and compact structure, working stability is reliable.
The working principle of this embodiment: the valve plate of type heavy-hammer type air-locking Flap valve is opened under the material gravity effect automatically, falls behind under the material, and the weighted lever system automatically resets valve plate, prevents that wild wind is blown into, thereby finishes the conveying of material.
This embodiment compact structure, working stability are reliable, have unload ash thoroughly, good airproof performance, lightweight, simple in structure, the characteristics such as be active in one's movements; Be widely used in the industries such as building materials, metallurgy, chemical industry, electric power, the discharge mechanism of giving as equipment such as the ash bucket discharge mechanism of all kinds of dusting apparatuss and various grinding machine, dryer, mashed feed bins prevents that wild wind is blown into.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
