Description

Adjustment doors axostylus axostyle seal arrangement
Technical field
The utility model relates to a kind of seal arrangement, is mainly applicable to the adjustment doors axostylus axostyle seal arrangement that pressurized container or pipeline adjustment doors prevent to external leakage.
Background technique
Thermal power plant is when pulverized coal conveying, dust, certain pressure can be applied in seal container or pipeline, in order to control the flow of coal dust or dust, adjustment doors can be installed at pressurized container or pipe-line system, but because traditional adjustment doors axostylus axostyle sealing is poor, therefore have coal dust at adjustment doors axostylus axostyle place or dust outwards sprays leakage phenomenon, cause the pollution of waste to material and environment.
Summary of the invention
The purpose of this utility model is a kind of adjustment doors axostylus axostyle seal arrangement of design, it is made up of flange slot, sealing gland ring, suction tude, clean air, sealer, the external diameter of sealing gland ring is equal to or less than the internal diameter of flange slot, and flange slot arranges suction tude, groove seat, axis hole, and groove seat arranges fixed hole, sealing gland ring arranges coaxial aperture, groove, vent, air cavity, groove is communicated with air cavity by vent, flange slot, sealing gland ring is arranged on axostylus axostyle, sealing gland ring is arranged on the bottom in flange slot, in the air outlet alignment indentation of suction tude, sealer is added in sealing gland ring exterior lateral sides, axostylus axostyle can at axis hole, rotate in coaxial aperture and sealer, groove seat is fastened on the sealed wall of container or delivery pipe by fixed hole, when having pressure in container or delivery pipe, clean air pressure being greater than sealed wall internal pressure enters in flange slot by suction tude, now spindle rotation or do not rotate, under the effect of clean air, dust in pressurized container or delivery pipe all can not to external leakage.
The technological scheme that the utility model solves its technical problem used is: it is made up of flange slot, sealing gland ring, suction tude, clean air, sealer, fixed hole, groove seat, sealed wall, axostylus axostyle, axis hole, coaxial aperture, groove, vent, air cavity, flange slot arranges suction tude, groove seat, axis hole, and groove seat arranges fixed hole.Sealing gland ring arranges coaxial aperture, groove, vent, air cavity, groove is communicated with air cavity through vent, the external diameter of sealing gland ring is equal to or less than the internal diameter of flange slot, axis hole, the diameter of coaxial aperture and the equal diameters of axostylus axostyle, flange slot, sealing gland ring is arranged on axostylus axostyle, sealing gland ring is arranged on the bottom in flange slot, in the air outlet alignment indentation of suction tude, sealer is added in sealing gland ring exterior lateral sides, axostylus axostyle can at axis hole, rotate in coaxial aperture and sealer, groove seat is fastened on the sealed wall of container or delivery pipe by fixed hole, when having pressure in container or delivery pipe, in flange slot, the clean air that pressure is greater than sealed wall internal pressure is added by suction tude, now spindle rotation or do not rotate, under the effect of clean air, dust in pressurized container or delivery pipe all can not to external leakage.
The beneficial effects of the utility model are: can prevent the adjustment doors axostylus axostyle position of pressurized container or pipeline to external leakage.
