Abstract
The utility model relates to a seal component, composed of a seal cover, a rubber sleeve, and an outer sleeve. The seal component is characterized in that an external diameter of the rubber sleeve is equal to an internal diameter of the outer sleeve; a top opening of the rubber sleeve is a taper-shaped opening; a seal cover is a hollow cover which has a horizontal cover crown at an upper part and a short pipe at a lower part; and an end face of the short pipe at the lower part of the seal cover matches a top end face of the rubber sleeve. The advantages are that the automatic compensation function is possessed; damping effect is also possessed; service lifetime is substantially increased; maintenance cost is reduced; manpower is saved; sealing effect is good; and safe operation of a machine is guaranteed.
Description
Technical field
The utility model relates to a kind of black box, and particularly a kind of black box that is used for coal pulverizer belongs to the Sealing field.
Background technique
In the coal pulverizer casing wearing plate is installed, wearing plate and coal pulverizer casing adopt bolt, need to install black box on the bolt, are used for preventing that coal, ash, water etc. from entering cabinet by the bolt slit.Because coal pulverizer vibrates when work, the black box that former machine is joined will occur the slit through wearing and tearing after a while after the wearing and tearing, causes often leaking and dust, has brought many troubles to production.
Summary of the invention
The purpose of this utility model provides a kind of black box that automatic compensation function and cushioning effect, good sealing effect, long service life, maintenance economize that has.
The purpose of this utility model realizes in the following manner:
The utility model is made up of sealing cover, rubber sleeve, overcoat, it is characterized in that: the external diameter of rubber sleeve equates with the internal diameter of overcoat, the top port of rubber sleeve is a taper mouth, sealing cover is that top has the horizontal cover hat, the bottom is the hollow cover of short tube shape, and the end face of sealing cover bottom short tube and the top end face of rubber sleeve match.
The utility model has the advantages that: have the function of automatic compensation, and also have the effect of damping, increased working life greatly, reduced the expense of maintenance, also saved manpower, good sealing effect has guaranteed the safe operation of machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is user mode figure of the present utility model.In Fig. 2, the camber line of bottom has represented to intercept the part of coal pulverizer casing.
Embodiment
With reference to accompanying drawing, the utility model is made up of sealing cover 1, rubber sleeve 2, overcoat 3, sealing cover 1 and overcoat 3 are made of metal, the external diameter of rubber sleeve equates with the internal diameter of overcoat, the top port of rubber sleeve is a taper mouth, sealing cover is that top has the horizontal cover hat, the bottom is the hollow cover of short tube shape, and the end face of sealing cover bottom short tube and the top end face of rubber sleeve match.
During use, wearing plate 5 usefulness bolts 6 are fixing with coal pulverizer casing 4, and the rubber sleeve 2 in the black box is enclosed within on the bolt shank, and overcoat 3 is enclosed within outside the rubber sleeve 2, and sealing cover 1 is enclosed within on the bolt shank, and is pressed on the rubber sleeve 2, is compressed by nut at last.When nut pressed down sealing cover 1, the taper mouth at sealing cover 1 extruding rubber sleeve 2 tops made rubber deformation, thereby seals up coal, ash, water.
