Abstract
The utility model discloses a direct-buried sealing sleeve compensator comprising an inner tube, an outer tube, a press cover, filter, bolts, a cover shell and sealing material. The inner tube, the outer tube and the press cover are coaxially sheathed, and the filter is filled in the space formed by the inner tube, the outer tube and the press cover. The bolts are axially connected with the flange edges of the outer tube and the press cover to form a sealing adjust structure. The cover shell is externally arranged at the sealing adjust structure. A right side plate of the cylinder cover shell is fixedly connected with the outer wall of the outer tube, and a left side plate and the outer wall of the inner tube are in gap matching. The outer side of the left side plate is fixedly connected with a ring sleeve which is coaxial with the inner tube, and the sealing material is arranged at the gap of the ring sleeve and the inner tube to form a sliding sealing structure. When in use, dirt on the outer wall of the inner tube is eliminated by the sliding sealing structure, and the normal movement of the inner tube opposite to the outer tube is not affected. Sealing pairs of the direct-buried sealing sleeve compensator run under clean environment, the filter loss is small, the sealing effect is good, and the use life is long.
Description
Technical field
The utility model relates to a kind of sleeve expansion joint of pipe safety device, particularly a kind of external jacket structure.
Background technique
The structure characteristic of sleeve expansion joint is that voltage endurance capability is strong, and it utilizes the interior pipe and the outer tube of coaxial fit to move to axial, rotatablely move or the end thrust and the bit shift compensation that take place in institute's pipe arrangement network operation made in above-mentioned two kinds of aggregate motions.Under some particular environment, the sleeve expansion joint of installing in the pipe network is positioned at underground more help safety and insulation.But the sealing regulation structure of the sleeve expansion joint of prior art is exposed structure, is subject to the dirt influence when being buried and causes akinesia, dirt to enter to accelerate the sealing material wearing and tearing behind the motion sealing pair and cause structure to leak.Owing to have above deficiency, make the Environmental Conditions of sleeve expansion joint be subjected to certain limitation.
The model utility content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of regulation structure that seals and is placed in direct-burried sealed type sleeve expansion joint in the case, and this casing structure is simple, good antifouling effect, the motion of the relative outer tube of pipe in not influencing.
The utility model is achieved through the following technical solutions technical goal.
Direct-burried sealed type sleeve expansion joint, it comprises interior pipe, outer tube, gland, filler, bolt, case and sealing material.Pipe, outer tube and the coaxial fit of gland in described, inner formed confined space is equipped with filler, and bolt axis constitutes the sealing regulation structure to the flange edge that connects outer tube and gland.Its improvements are: described sealing regulation structure peripheral hardware case, columniform case right sideboard is fixedlyed connected with outer tube outer wall, left sideboard and outer wall of inner tube Spielpassung, the fixedly connected ring set in the left sideboard outside, ring set is coaxial with interior pipe, at both gap locations sealing material is installed and is constituted the slipper seal structure.
In the said structure, the sealing material that is installed in the case left side slipper seal structure is the O RunddichtringO.
The utility model compared with prior art has following good effect:
1, in the motion of sleeve expansion joint sealing vice division chief case is set, simple in structure, make easily;
2, be provided with the slipper seal structure between case and the outer wall of inner tube, the dirt of removing on the outer wall of inner tube is effective, and manages the proper motion of relative outer tube in not influencing;
3, sleeve expansion joint moves under clean environment, and the filler loss in the sealing regulation structure is few, good sealing effect, long service life.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Direct-burried sealed type sleeve expansion joint shown in the drawings, pipe 1, outer tube 2, gland 3, filler 4, bolt 5, case 6 and sealing material 7 in it comprises.Pipe 1, outer tube 2 and gland 3 coaxial fits in described, filler 4 is equipped with in formed space, and the flange edge that bolt 5 axially connects outer tube 2 and gland 3 constitutes the sealing regulation structure.At sealing regulation structure place peripheral hardware case 6, columniform case 6 right sideboards 6.1 are fixedlyed connected with outer tube 2 outer walls, left sideboard 6.2 and interior pipe 1 outer wall Spielpassung, the fixedly connected ring set 6.3 in left sideboard 6.2 outsides, ring set 6.3 is coaxial with interior pipe 1, at both gap locations sealing materials 7 is installed and is constituted the slipper seal structures.
During actual the use, drop on the dirt on pipe 1 outer wall in the sleeve expansion joint, along with the motion of interior pipe 1 relative outer tube 2 is blocked by the slipper seal structure, dirt does not advance in the sealing regulation structure of sleeve expansion joint, guaranteeing to seal regulation structure is moving under the clean environment relatively, thereby realize that the filler loss is few, good sealing effect, the purpose of long service life.
