Abstract
A sleeve compensator relates to the technical field of a compensation device of thermal fluid pipeline. A main pipe and outer wall of rear half section of an extension pipe are on the same shaft in a sleeve connection mode. A press cover is sleeved between the front end of the main pipe and the outer wall of the extension pipe. A plurality of sealing pieces are arranged closely on the rear side of the press cover. A first retainer ring is arranged on the rear side of the sealing pieces. A first compaction flange is sleeved on the outer wall of the front end of the press cover. A second compaction flange is sleeved closely on the outer wall of the frond end of the main pipe. The first compaction flange and the second compaction flange are fixedly connected through a plurality of groups of bolts, nuts and flat gaskets. A second retainer ring is welded on the outer wall of the rear end of the extension pipe. A bushing ring is welded on the inner wall of the rear end of the main pipe. The sleeve compensator has the advantages of a large amount of compensation, convenient maintenance, high safety performance, long service life, wide range of application, low construction cost, a vast market foreground and a high study design value.
Description
Technical field:
The utility model relates to the compensation device technical field of hot fluid pipeline, is specifically related to a kind of novel slip-type expansion joint.
Background technique:
Slip-type expansion joint claims again the tubular type slip joint, it is the compensation device of hot fluid pipeline, being mainly used in rectilinear duct and additionally arranging the axial thermal expansion displacement absorption compensation of rear appearance, is the compensator among a kind of pipeline that is directly installed on the free from corrosion unidirectional or multidirectional fluid of any conveying.Slip-type expansion joint is widely used in the conveyance conduit of the industries such as cities and towns heating, metallurgy, mine, generating, petrochemical industry, building, is applicable to hot water, steam, grease class medium, medium engineering pressure≤2.5Mpa, medium temperature-40 ℃～600 ℃.
The slidingsurface of sleeve expansion joint 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.But also there is certain deficiency in present slip-type expansion joint: as less in compensation rate, maintenance is inconvenient, Safety performance is not high, the more high defective of cost, and can not satisfy people's user demand, and be unfavorable for applying.
The model utility content:
The purpose of this utility model is to provide a kind of slip-type expansion joint, and it has, and compensation rate is large, easy to maintenance, Safety performance is high, long service life, and using scope is extensive, and engineering cost is lower, has the high value of wide market prospects and research and design.
in order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises telescopic pipe 1, the first supported flange 2, the second supported flange 3, gland 4, Sealing 8, the first back-up ring 9, the second back-up ring 10, main body tube 11 and grommet 12, the outer wall coaxial sleeve of the second half section of telescopic pipe 1 is connected to main body tube 11, and closely be socketed with gland 4 between the outer wall of the front end of main body tube 11 and telescopic pipe 1, the rear side of gland 4 closely is provided with several Sealing 8, the rear side of Sealing 8 closely is provided with the first back-up ring 9, the front end outer wall of gland 4 closely is socketed with the first supported flange 2, the front end outer wall of main body tube 11 closely is socketed with the second supported flange 3, and the first supported flange 2, the second supported flange 3 is by array bolt 5, nut 6 is fixedly connected with plain cushion 7, the rear end outer wall of telescopic pipe 1 is welded with the second back-up ring 10, the rear end inwall of main body tube 11 is welded with grommet 12.
The seal ring of described Sealing 8 for adopting flexible graphite material to make, it is large that it has intensity, friction factor little (0.04～0.10), high temperature resistant, corrosion protection, anti-aging can guarantee to endwisely slip, and can guarantee again to manage interior medium and not leak.
Principle of the present utility model is: the second back-up ring 10 is welded on the rear end outer wall of telescopic pipe 1, has the anti-slip function, has improved the ability that product meets accidental contingencies, and can guarantee the network security operation.Simultaneously, the nonelastic power of compensator during work, thrust is little.When Sealing 8 wearing and tearing caused sealing effect to weaken, fastening the first supported flange 2, the second supported flange 3, strengthened sealability again, also bolt 5 can be unclamped, and takes off gland 4, refills into one deck or two-layer Sealing 8, compresses the rear continuation of gland 4 and use.
The utlity model has that compensation rate is large, easy to maintenance, Safety performance is high, long service life, using scope is extensive, and engineering cost is lower, has the high value of wide market prospects and research and design.
