Abstract
The utility model relates to a direct-buried self-press type seal sleeve compensator, which is used for compensating the displacement of medium delivering pipe and widely applied to pipeline used in heat supply field, metallurgy field, petrochemical field and architectural field. The compensator comprises an external sleeve, an internal sleeve, an internal-external baffle ring, an internal-external flexible stuff, an internal-external pressure ring, a spout, a sealed body consisted of sealing stuff, a buried jacket, a buried sealed ring and a buried sealed member consisted of buried flexible stuff. The flexible stuff, pressure ring and sealing stuff are squeezed reciprocally under the pressure of the medium in the pipe to form a self-press type sealed body without leaking of the medium in the pipe. The sealed body is made of wear-resisting and lubricating material, which is benefited to the sliding movement of the internal sleeve. The buried sealed ring, welded together with the internal sleeve, is moved along the internal sleeve in the buried jacket to protect the surface of the internal sleeve from scratch in displacement compensate.
Description
Technical field
The utility model relates to a kind of direct-burried self-pressure type seal sleeve compensator that is used for medium transport pipeline bit shift compensation, and it is widely used in the pipe-line system of industries such as heat supply, metallurgy, petrochemical industry, building.
Background technique
The sleeve expansion joint of existing medium transport pipeline application because compensator inner stuffing sealing effect is bad, causes pipe leakage, influences the normal operation of pipeline, brings serious economy loss for production and life; If the compensator direct-burried is in underground, the cover surface influenced sealing in the sandstone in the soil can scratch, and caused pipe leakage.Inspection-pit must be set for this reason, improve engineering cost.
Summary of the invention
For solving the bad problem of sleeve expansion joint inner sealing effect, it is directly buried type that the utility model provides a kind of change external structure, can not establish inspection-pit during application, reduces the direct-burried self-pressure type seal sleeve compensator of pipeline engineering cost.
The purpose of this utility model is to realize like this, this compensator comprises by overcoat, interior cover, interior outer baffle ring, inside and outside flexible packing, the external and internal pressure ring, material feeding is chewed, the sealed body that stuffing box packing constitutes and by the direct-burried sheath, the direct-burried seal ring, the flexible packing of direct-burried constitutes two parts of direct-burried sealed body, be provided with interior outer baffle ring between overcoat and the interior cover, the inboard of interior outer baffle ring is respectively arranged with inside and outside flexible packing, the inboard of inside and outside flexible packing is respectively arranged with the external and internal pressure ring, is provided with stuffing box packing in the middle of the external and internal pressure ring, puts corresponding stuffing box packing place outward and be provided with material feeding and chew; The direct-burried sheath is sleeved on outside of inner cover, is connected with overcoat, is provided with the direct-burried seal ring between outside of inner cover and direct-burried sheath, and the direct-burried seal ring is connected with the inner sleeve, and direct-burried seal ring internal recess is provided with the flexible packing of direct-burried.
Described inside and outside flexible packing and the flexible packing of direct-burried contain wire, and the external and internal pressure ring is made by graphite, has the inclined-plane on it.
The distance of described direct-burried seal ring and sealed body is the compensation rate of compensator.
Structural feature of the present utility model:
1. include flexible packing wiry and under the effect of pressure ring, form rigid backbone, compress overcoat Seal cage inwall and interior cover;
2. the ramp structure of pressure ring makes under its squeezing action of pressing in filler and pipeline medium, compresses flexible packing, compresses interior cover simultaneously, makes pressure ring and interior cover not have the gap.
3. direct-burried seal ring and interior cover are welded into one, and coexist with interior cover one and move in the direct-burried sheath, and its internal recess is provided with flexible packing, have avoided being used for the interior cover surface of compensate for displacement to slide with outside soil.
Advantage of the present utility model and good effect:
1, flexible packing, pressure ring, the stuffing box packing mutual extrusion under the pressure effect of pipeline internal medium in the sealed body forms a self-pressure type seal, and pipeline internal medium is not leaked; Material in the sealed body is wear-resisting lubriation material, and cover slides in helping.
2, direct-burried seal ring and interior cover are welded into one, and coexist with interior cover one and move in the direct-burried sheath, and guaranteeing to be used for the interior cover surface of compensate for displacement does not have scuffing.
3, this structure direct-burried need not overhaul in underground, and inspection-pit need not be set, and has reduced engineering cost.
