Abstract
A filling type sleeve expansion relates to the technical field of sleeve expansion. The filling type sleeve expansion comprises an inner sliding extension tube, a gland, a guiding sleeve filling openings, a graphite ring packing and an outer sleeve. The inner sliding extension tube is slidably arranged at the inner wall of the guiding sleeve. The outer sleeve is closely arranged at the outer wall of the guiding sleeve. A flange is arranged at the front end of the outer sleeve. The gland is sleeved at the front end of the guiding sleeve and the gland is connected with the flange through a bolt. A plurality of filling openings is uniformly arranged at the outer edge of the outer sleeve at the rear end of the flange. The graphite ring packing is arranged between the inner sliding extension tube at the rear end of the guiding sleeve and the outer sleeve. The filling type sleeve expansion is simple and reasonable in structure and less in welding process, thereby reducing manufacturing steps and increasing efficiency.
Description
Technical field:
The utility model relates to the sleeve expansion joint technical field, is specifically related to a kind of filling type sleeve compensator.
Background technique:
Filling type sleeve compensator claims the tubular type slip joint, is the compensation device of hot fluid pipeline, is mainly used in additionally arranging of rectilinear duct.Be applicable to hot water, steam, grease class medium, by the sliding motion of interior slip pipe to outer sleeve, reach the compensation of thermal expansion.Slip-type expansion joint is applicable to medium engineering pressure≤2.5Mpa, medium temperature-40 ℃-600 ℃.The working life of filling type sleeve compensator is large, and fatigue life and pipeline are suitable.Slidingsurface is through special processing, and corrosion resistance and good under the environment such as salt solution, salt solution is higher more than 50 times than Austenitic Stainless Steel.Simultaneously, when causing sealing effect to weaken because of wearing and tearing after for many years, clamp flange strengthens sealability again, also bolt can be unclamped, and takes off trim ring, refills into one deck or two-layer seal ring, compresses trim ring, continues to use.
But also there is certain deficiency in present filling type sleeve compensator,, complex production process more such as: complex structure, welding procedure etc.
The model utility content:
The purpose of this utility model provides a kind of filling type sleeve compensator, and it is simple and reasonable, and welding procedure is less, has reduced production stage, raises the efficiency.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises interior slip pipe, gland, guide sleeve, notes are filled out mouth, graphite annulus filler and outer sleeve, interior slip pipe slidably is arranged on the guide sleeve inwall, the guide sleeve outer wall closely is provided with outer sleeve, the outer sleeve front end is provided with flange, the guide sleeve front end sleeve is connected to gland, and be bolted between gland and the flange, evenly be provided with several notes on the outer sleeve outer rim of flange rear side and fill out mouth, be provided with the graphite annulus filler between the interior slip pipe of guide sleeve rear end and the outer sleeve.
Described interior slip pipe end is provided with several stop screws.
Principle of the present utility model is: during work, the relative sliding in relying between slip pipe and the outer sleeve comes the extending amount that expands with heat and contract with cold and produce of extraction duct.Realize sealing by the Seal cage that is formed by graphite annulus filler and sealing compound between interior slip pipe and outer sleeve.Sealing compound is filled out mouthful depended on pressure from notes and is injected, and can after-teeming under the pipe network operation state, and maintenance does not stop production.Since interior slip pipe end use instead stop screw carry out spacing, simpler than welded limiting block technique in the prior art, convenient production.
The utility model is simple and reasonable, and welding procedure is less, has reduced production stage, raises the efficiency.
Description of drawings:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the left view of Fig. 1.
Embodiment:
With reference to Fig. 1-Fig. 2, this embodiment is by the following technical solutions: it comprises interior slip pipe 1, gland 2, guide sleeve 3, notes are filled out mouth 4, graphite annulus filler 5 and outer sleeve 6, interior slip pipe 1 slidably is arranged on guide sleeve 3 inwalls, guide sleeve 3 outer walls closely are provided with outer sleeve 6, outer sleeve 6 front ends are provided with flange, guide sleeve 3 front end sleeves are connected to gland 2, and be bolted between gland 2 and the flange, evenly be provided with several notes on outer sleeve 6 outer rims of flange rear side and fill out mouth 4, be provided with graphite annulus filler 5 between the interior slip pipe 1 of guide sleeve 3 rear ends and the outer sleeve 6.
Described interior slip pipe 1 end is provided with several stop screws 7.
The principle of this embodiment is: during work, the relative sliding in relying between slip pipe 1 and the outer sleeve 6 comes the extending amount that expands with heat and contract with cold and produce of extraction duct.6 Seal cage realization sealings by being formed by graphite annulus filler 5 and sealing compound of interior slip pipe 1 and outer sleeve.Sealing compound is filled out mouthful 4 depended on pressure from notes and is injected, and can after-teeming under the pipe network operation state, and maintenance does not stop production.Since interior slip pipe 1 end use instead stop screw 7 carry out spacing, simpler than welded limiting block technique in the prior art, convenient production.
This embodiment is simple and reasonable, and welding procedure is less, has reduced production stage, raises the efficiency.
